Samsung Gear smartwatch, not so impressed.

Samsung has recently announced its new smartwatch, the Gear.

As someone who likes his gadgets and that sort of technology-type stuff, a practical smartwatch linked through to my phone could be something I’d have in interest in. This watch has a workable colour screen 4 cm across and resolution of 320 by 320, and with all the things you might expect from such a device in the way of a camera and talking to your (Samsung) phone. (Compare this resolution to when desk top PCs first hit the mass market with monitors of 14 inches / 35.5 cm and a resolution of 640 by 480.)

However the one thing that totally kills it for me is the battery life. Samsung’s talking about a day’s use (and that’s when new!) which is just not what would interest me.

For something like this I need to know I can go away for a long week-end, use is extensively (but still sensibly) without any worry of it going flat or need to have to take a charger with me. So we’re talking about charging it Thursday night, going away Friday, then Sat and Sun out adventuring, heading back Monday for a Monday night charge, and doing this confidently knowing that it’s going to remain a working useful device for the whole period.

It would have been nice if they had managed to build into it a self-winding system similar to an automatic mechanical watch. This would have worked a small generator to help keep the battery charged as you move. There’s nothing special in this, kinetic-based quarts watches have been doing this for some years.

I guess it’s the usual story of never buy the early versions of anything, wait for the second generation to arrive.

My YouTube thoughts on it.

Resolution size and quality

Video resolution, file size and image quality.

A while ago I thought I’d take my camera out for an afternoon’s videoing and so headed off to Linlithgow Palace. Once I’d got some editing done I found I had a video of just under 10 minutes in length. Usually I render out at 720p for a YouTube or Vimeo upload, but this time I thought I’d render at 1080p just to see how things went. At the end of the processing I found myself with a file of just over 2 gigabyte. This I thought a little bit large for uploading from home so went up to Uni did my upload (to Vimeo) from there. That went nice and fast, in fact it uploaded faster than the length of time it took me to type out title, description and all that sort of stuff. Once back home thought I would re-render it but this time in my more usual 720p (other settings the same) just to do a compare and contrast. My just under 10 minute came down at just over 400 megabyte.

So we’re talking about one fifth the size of the 1080p video. Playing the two videos side by side it was hard to notice any difference in quality, it was there but you really had to pick around the edges to see it. Now and again I’d pause at a suitable moment where perhaps a a sign was in view or maybe a car number plate or something similar and try and read it, and it was more readable in the 1080p version. However as a flowing video it was quite difficult to tell the difference between the two, yet the 720 giving me so much more free hard drive space compared to 1080.

I also rendered it out in standard definition quality at 360p size (looking towards uploads for mobile devices or older smart phones). Here we had a file size of just under 60 megabyte, or a little under 3% of the 1080p file size. Comparing the video here to the others there was a very definite reduction in quality. It still wasn’t too bad to watch, however when you had this 360 next to either the 720 or 1080 the difference really jumped out at you. On the other hand it was still more than good enough for a portable device if you were on the train.

Something to think about. Take the 1080 HD video size, which is a 1920 by 1080 rectangle. Multiply that out and it comes to just over 2 million pixels. Or to put it another way, if you’re in a shop talking about video and cameras and the sales staff are busy trying to sell you this camera rather than that camera because this camera has more mega pixels on the sensor… well, if you’re going to actually film at the native HD resolution then all you really need is this just over 2 mega-pixel size sensor. Bigger does not always mean better.

 

Premiere Pro or Final Cut?

Premiere Pro or Final Cut, which do I prefer.

I got my first proper video camera about 5 years ago, a small Panasonic non-HD camera (HD was around, but rather expensive for something I only wanted to experiment with), and like many people my first editing experience was with Windows Movie Maker. I soon realised that doing this was quite fun, and as this luckily coincided with a sharp fall in HD camera prices, I got myself a nice Canon HD camera.

At the time Windows Movie Maker would not do HD video so I bought a copy of Corel’s VideoStudio X2. However as time went on I wanted to do more with VideoStudio than what I was.

As I was also needing an upgrade for my PC I thought I’d basically start again, but rather than buy a new computer and then find software for it and then find how to use it I thought I’d firstly find some good video editing tutorials, see what software they was using, then see what hardware was needed for running that software. After a bit of browsing around (and some really horrific tutorials on YouTube) I came across a site called IzzyVideo, run by Izzy Hyman. He has done some really good tutorials (some free, some subscription only), both on editing techniques and on general video creation. What software was he tutoring on – Final Cut Pro 7 and Final Cut Express. What hardware does that need – Apple Mac.

Final Cut 7 was a bit expensive for me, plus it was overkill for what I wanted, but Final Cut Express, especially at education price made sense. Likewise I couldn’t afford a new Mac but a friend sourced a second hand MacBook for me. So that sorted that out, I’ll move across to Mac and go Final Cut Express.

Time goes by and there’s then the release of Final Cut Pro X (and all the controversy that caused!). It was released without quite a few features considered essential by the serious film making community, however for my use it was great, especially as Izzy Hyman very quickly released some great tutorials for it.

Time goes by again and I find myself playing with Photoshop CS6 and it’s through its limited video editing abilities I became aware of Premiere Pro. I also realise I could do with a system with more powerful graphics than what I was currently using. My two generations’ old MacBook Air seems to run all this software well enough for me, but it’s not really an ideal machine for this sort of thing. Then by chance I found myself having access to a more powerful Windows system and at the same time found some good Premiere Pro tutorials up on the Creative Cow web site so I thought I would give it a try (and taking advantage of Premiere Pro being for both Windows and Mac).

Both Premiere Pro and Final Cut are non-linear editors where you can chop and change video clips and drag them around. Both have numerous different effects built in and you can adjust white balance and sort out colour correction. Titles and captions can be added and both have audio editing facilities. The only real restriction on them is your imagination as to what you want to do!

On both, where my original video has been a couple of simple clips, perhaps me just talking about a film I’ve seen recently and have not required a significant amount of processing I’ve had the whole process of import, clip editing, sound adjustment, and then rendered out ready for YouTube upload all done well within an hour. So if things go well and you’ve got it right in camera at the video recording stage then for short videos things can be done really quickly.

One thing I like about Premiere Pro compared to Final Cut is that it is more flexible when it comes to reading video files. I copy the recordings across from my camera onto my computer hard drive and Final Cut wants to see the whole file structure of the AVCHD directory, and if anything is played with or altered or deleted anywhere within that directory tree then Final Cut can throw a bit of a hissy fit and doesn’t want to work with the files, where with Premiere Pro you can happily use your system’s file manager to tunnel down into the directory and into the individual recording clips, get rid of the ones you don’t want, copy across into this area others you might want to use and Premiere Pro is still quite happy with everything.

Final Cut also wants to transcode new clips before it will use them which can delay getting started where Premiere Pro will run clips natively, but then I’ve found for editing Final Cut does seem to run that bit more smoothly. It also just needs say two or three actions to complete a task where Premiere Pro may need three or four actions. There’s one area I’ve found Final Cut to be far better at, and that’s with green screen / chroma key editing. I can get a good key sorted out far quicker and with better results  compared to Premiere.

Both can be a bit fiddly when it comes to settings for exporting and both take their time for the final rendering processing. This is where the more powerful hardware really comes into play for cutting down that time.

I’ve found both Premiere Pro and Final Cut great products. Skills learnt through using one are quite transferable across to the other. Both have been fun to use, on the other hand both have given me headaches at times.

Overall, I think if I was just going to be doing standard video editing and only video editing, then I’d choose Final Cut. Since it came out they have updated it with most of those missing features that weren’t there at time of release. However as I’m going to be playing around with Photoshop as well and the way Adobe is enabling their different programs to smoothly interact with each other means that for the time being I’m going to stick with Premiere Pro.

What I would suggest to anyone whose currently undecided is to find a suitable tutorial web site (I found Creative Cow quite good), compare the tutorials for one against the tutorials for the other and then decide on which you would feel most comfortable using.

I’ll will also add that I did briefly play with Avid, however although it’s education price is quite competitive I did find it rather klunky to use and it didn’t settle down to it. I just found it a bit too irritating. I could see it had huge potential, however it wasn’t for me.

Bebo

Things happening at Bebo.

I’ve just noticed a comment in the press saying that Michael Birch, one of the founders of Bebo, has actually bought it back in some bankruptcy sale for around $1 million – if we go back in time a bit to Bebo’s peak, I think Birch sold it off to AOL for something around $850 million. That was at a time where in many countries Bebo was the dominant social networking site, this being at a time before Facebook had really started its rise to domination.

I do remember at the start of an academic year walking through one of the computer areas in my campus library and noticing one or two of the students had this Bebo site up on their screens. At that time I had not heard of it before and was curious as to what it was. Fast forward 12 weeks and we’re almost at the Christmas break, walking through the same computer area again and found an almost exact opposite situation – where there were only one or two people who did not have a Bebo window up somewhere on their monitor. It really had gone from nowhere to everywhere that quickly. However Birch then sold it off to AOL, and once they got their hands on it they did their usual thing and made a total pig’s ear of it.

The faster something rises up then the faster it can fall down, and so under AOL’s guidance it rapidly descanted into almost total oblivion and irrelevance. AOL in turn sold it on to Criterion Capital Partners. However it did maintain (and still does as far as I can tell) a sort of core number of active users on the site.

Now that Michael Birch has paid $1 million to get it back I wonder what he’s got planned for it. He can’t just re-invent it as it was, Twitter and Facebook have taken that ground away from him. So what will he do?

I think it is going to be a case of ‘I’ve no idea’, because if it was that obvious such that I could think of it someone else would have already done it, so he’s going to have to come up with something quite novel and new.

After all, it is one thing to develop a brand new site that no one has ever heard of so it doesn’t have either a good or bad reputation; it’s another thing to pick up an old site which is seen by many as a bit of a joke and to try and turn it around. On the other hand he has got a well-known brand name behind him again. We’ll just have to see what he does with it, I’m almost tempted to sign up again purely to keep an eye as to what may develop.

MacBook Air or MacBook Pro?

One or two people recently have been talking to me about buying either a MacBook Air or a MacBook Pro.

Both I think are pretty awesome devices, I have an 11″ MacBook Air and think it’s great. It’s done everything I’ve asked of it including using Final Cut and Premiere Pro for video editing. Okay, it’s certainly not my first choice of editing devices, the rendering times are not that fast, but for a quick on-the-move video creation it can do the business (and if it can do that then it can do most things).

The Air is nearly half the weight of the Pro and its power charger is also lighter which makes it a very portable package. The Pro with its extra weight and thickness can pack a far more powerful processor, memory and allows for a larger range of hard drives. Pro options also allow for a proper dedicated graphics processing card which would make it a far more games (or video editing) friendly machine. The Pro is quite a bit more expensive.

So for me it boils down to this. Is this laptop going to be solely used as a laptop in that you do have an alternative desktop machine to use at home (or work), or is this laptop also going to be used as a desktop substitute?

If just as a laptop then I’d go Air and take advantage of its lightness and portability. If it was also going to be used as my main desktop machine too, then I’d go Pro.

What I do find interesting is that when the Air first came out it was seen as a premium product, something a bit different and priced well above the basic MacBook range of laptops. Now its their ‘budget model’. Amazing how things change.

YouTube video about it.

VEDA thoughts

Been a bit distracted over the last month uploading a video every day in April (VEDA) to YouTube.

This VEDA thing is not as easy as it sounds and many an experienced vlogger has tried but failed to achieve it.

It can start off easily enough. Everybody has those few things they like to talk about, however once you’ve got them sorted plus a few other things you want to have a good rant over, then finding something to say *every day* (remembering you have to record, edit and then upload) for the rest of the month can be really demanding. No break, no taking a day off, every day a new video has to be processed.

This is definitely something where that phrase ‘proper planning prevents piss poor performance’ (or whatever your own variation of it happens to be) really comes into its own. In a way it should not be that difficult.

The first day an introductory video, the last one wrapping things up. That leaves 28 days, or 4 weeks to be covered. Four weeks, then how about 4 stories, each story told in 7 instalments and each instalment being about a minute long. (Can’t be that difficult can it?)

Or rather than 4 stories, give each day a theme. Mondays cover your favourite foods, Tuesdays about music, Wednesdays about work (school / college), Thursday films… You get the idea, give yourself some proper structure to work around.

Just noticing that it’s about to start and saying to yourself ‘sod this I’ll give it a go and see what happens’ is not really the best way to go about things. However I did manage to do an upload every day (split across two different channels) so in that respect VEDA was achieved, but a little bit of thought and pre-planning would have made things so much easier, more enjoyable, and produced far better quality output.

Technology Firsts

Two of my Technology Firsts.

My first computer technology experience involved buying a Sinclair ZX81 computer, and in a way it was my first technology disappointment. It was a small, light ‘home computer’ that came with 1k of memory (though I did get its 16k expansion pack) and fed its monochrome output to a television. It was, in its own way a fun device to use and could even play a far better game of chess than I ever could. (You try today to get someone to write a fully working chess game using less than 16k of ram!) However what let it down was an awful membrane keyboard, but what really killed it for me was an unreliable program loading and data saving system. The device had no internal storage system so you had to use a domestic cassette deck connecting its headphone and microphone sockets into the side of the ZX81. This was so temperamental and unreliable – getting the cassette player playback and record levels correct, sorting out cassette start and stop routines – it made using the ZX81 a real pain.

I could see that computers were the way to go, so later replaced this with a Commodore VIC-20. What I liked about the Commodore (compared to the then available Sinclair Spectrum) was that the Commodore had a really nice typewriter style keyboard and its own dedicated cassette tape drive for data storage.

Another technology first was my first mobile phone – a Sony CM-R111. This was a wonderful device. It could only do one thing – make phone calls – but I really loved it to bits. A small device which almost fitted in the palm of your hand (at the time when so many were large chunky ‘bricks’) and with a rather novel flip-down microphone. This was at the time when the mobile system was an analogue one, so no text messaging or fancy data systems, just simple phone calls!

Google Reader

So Google is shutting down Reader.

In one way I’m not too concerned, I never seriously used Google Reader so I won’t miss it. However it makes me wonder how much I can rely on Google’s current services. They do seem to be developing a habit of just as people are getting used to something or getting to rely on it they’ll either close it down or ‘integrate’ it into something else. For some things it really doesn’t matter, but where you’ve spent time and money developing your own system around it or you use it in some financial way then things may be different.

I hadn’t realised how many services they had killed off till I did a Wiki search on the subject, and that threw up a list of over 70 of them. Okay, sometimes something can quite simply be a failure and is just a drain on resources so needs to go. Other times technology (or life) has moved on so the service needs to be re-developed, but when something like Reader is killed off at virtually no notice I’ve got to be thinking what’s next on the chopping block – perhaps something I do regularly use and rely on.

This has got me thinking that perhaps I should be duplicating more of my Google based services across onto Yahoo or see what Microsoft are doing regarding ‘the cloud’. I can’t say that I’m that keen on Yahoo and don’t particularly like Microsoft, it will mean that even more of ‘big brother’ will be watching me, but then they’re watching me anyway!

One thing it will be and that is a bit of a pain keeping things synchronised when copied across to different service providers,  however this has been a wake-up call / reminder of the importance of having alternative back-ups!

 

Internet Privacy

 So what about internet privacy and being anonymous.

My main browser is Google Chrome, and on machines I regularly use I have it set up so things like my bookmarks automatically come up. I also use YouTube, Google calendar and various other Google services, so I know (and accept) that Google is ‘watching me’. I’m happy enough (realistic enough) to accept that my level of internet privacy is rather limited.

I also use Firefox, occasionally Opera, and very occasionally Internet Explorer – usually just for those sites that insist on only working with IE (almost always work related ones that I can’t avoid).
When it comes to searching, then it’s usually Google. Occasionally I’ll try Bing or Yahoo, not for any special reason other than as something different for a change. They do actually throw up quite different results – try searching for your own name and see the different number of hits they show.

Early Saturday afternoon and it’s time to head into the city. A couple of places I wanted to go to so a quick internet search to remind me of their locations. However rather than search through Google I thought I’d try using ixquick (which claims to be the world’s most private search engine). I’d heard of it and was curious to see how it performed, which was exactly as expected. It threw up a page of sensible responses, and even from the couple of lines displayed against each of the results I could see enough of an address to remind me where these places were.

What surprised me was that ten minutes later when I picked up my (Android) phone was to see a message from Google giving me directions to one of the places I’d searched for through this ‘private’ search engine.

What I suspect had happened was that browsers often automatically start to download any links that are on the page being looking at, so if you then click on the link that new page will appear so much more quickly. On my search page one of those links will have been a Google Maps page, Google will have recognised the machine this request came from and promptly, being extra-clever (!!!), sent to my Android / Google powered phone instructions on how to get there.

There’s more to keeping yourself private on the internet than people realise!

Student Confidence

Something I see quite often with the higher education students I’m around is a loss of confidence in themselves.

On the surface they appear to be growing, both physically and mentally, but underneath not all is well. Most I see come straight from school, teenagers, where they have worked themselves up to ‘top-dog’ position within their own school hierarchy. They come in to start their degree courses and it’s all new and novel. For many it’s the first time they’ve truly been away from parental control! This is all something different to be explored, they’re often a bit nervous but it’s still really exciting. This is at the start, what about at the end.

The courses I see them do typically last five years, so having come in full of the joys of proverbial youth they are leaving as adults. Maybe relatively young adults, but still very much adults.

They’ve grown up!

Sometimes this transition into adulthood can happen quite quickly. I’ve seen students I’d class as teenagers at the start of a semester, but by the end, 12 weeks later, I realise I’m talking to an adult. That’s a fast change! More usually it’s a gentle development spread over three or four years. However for some it can cause problems.

As they start to grow up there is the realisation and appreciation that their actions do have consequences, and in turn other people’s actions have consequences upon them. Things you did as a teenager would just be passed off as a bit of fun, as a bit of youthful exuberance. It really didn’t matter as tomorrow would be another day and yesterday would soon be forgotten. Now however those same actions are viewed differently, you are being held responsible for your behaviour in the same way that you now hold others responsible for their behaviour. So there develops a need to gain the approval and acceptance from others of what you’re doing, you can’t just brush things off as if they don’t matter.

For some this is just part of growing up. For others it can make them stop and question what they did before, and this in turn lead to uncertainty as to what they are doing now. When 17 or 18 I thought I was reasonably grown up and mature, but looking back I can see I really wasn’t. How could I have had that attitude then, but I currently now think I’m ‘gown up and mature’, so in reality are my current activities of similar worthlessness?

What about the future? As a teenager I saw the future as just something out there, for tomorrow, not now; but ‘now’ has arrived and there’s uncertainty as to what will happen tomorrow. (All through education you had a fair idea where you would be this time next year – back in the class room; but once you get into final year, where will you be in 12 months’ time – you will not be here!)

For some this can lead to a crisis of confidence in themselves. Where are they going and what do they want to do with themselves. Uncertainty which in turn can lead to depression; a mix of not knowing and what’s the point anyway. Usually by the time it comes to them leaving with their degrees most have developed enough to get a workable amount of control back into their lives. For others though, uncertainty can remain. However in current society showing ‘weakness’ is itself seen as being weak, so up go the false walls and barriers.

But like it or not, it is eventually time for them to move on, life does not stand still. Whatever happens, you just have to do the best you can to suit whatever situation you find yourself in. That’s life!
