Having a virtual camcorder in your pocket (well, in your smartphone) means being able to grab ad-hoc moments for posterity. But how embarrassed will you be with the quality when these moments are later burned onto DVD and played back through a proper TV? I investigate....
Read on in the full article.
Not able to view the videos in Safari here, Steve...
EDIT: Or maybe they aren't actually videos, just screenshots..? Stupid me...
ROFL!!!
Yes, they're screenshots, but are grabbed from real video versions. Easy to compare relative video picture quality etc.

Don't know how easy this is Steve, but if it's no bother you might want to add 320x240 as an increasing number of lower end S60s seem to record video at this resolution.
Well, that's not that dissimilar from 352 by 288, of course. Just a little worse. In either case, the point of my piece was that it's still way too low for nice clear videos 8-)
OK, for YouTube at a pinch, I guess. But you'd still get better quality by starting with a higher resolution original from which you can 'sample down' in video software...

"OK, for YouTube at a pinch, I guess. But you'd still get better quality by starting with a higher resolution original from which you can 'sample down' in video software..."
Yeah, it's true! I wonder why this is the case though. Why does a video shot at 320x240 look worse than a video shot at a higher res and shrunk down to 320x240?
Well, in theory it shouldn't, of course. But 320 by 240 grabbing devices are usually hanging on by the skin of their teeth and there are lots of compression artefacts. Capturing at VGA, so that artefacts are at that level and then intelligently resampling down in video software seems to give more detail and better results.

This "investigation" is retarded. Scaled up videos are smoothed, not pixelated like this shit.

I think you are the retardate. Actually it is exactly the opposite. That's why pictures/videos look perfect on your device's screen and not so good on PC.
Listen retard, video players used to smooth (anti/aliasing) magnified videos.
Yeah, yeah... you're a video specialist, excuse the way I see videos...
I don't think anyone here is a retard, but a serious lack of social skills is obvious in some people.

Don't be so sure, you don't know me 😃
Children, children. Now I actually am a video specialist with a BSC (Hons) in Film Production Technology and I work at the UK's largest educational institution (not being big-headed, just trying to explain I am qualified).
Granted a lot of televisions employ algorithms to interpolate, anti-alias and de-/interlace and can also apply preset amounts of 'smoothing' to these images - indeed, so do many high end encoders usually for encoding low-res content for web. It still doesn't look great though - all of these techniques will never come close to having that resolution in the first place.
Steve has simply given a straight-forward comparison or illustration of differing resolutions and what they may look like on a television set. Surely all can assume that this may vary from display to display and phone to phone without the need for a disclaimer!?
Good overview Steve, it's nice to hear that there are higher resolution devices on the horizon - hopefully with a VGA screen also and (probably only in my wildest dreams, not that I dream of such stuff 😛) a decent battery!

Well, how about this display?
Very good ratza, though I mean by Nokia. Something of similar size to the N95 - would rather it be a little bulkier and heavier - with a 3 inch or higher screen with 640x480 or higher with a slide-out qwerty keyboard as well as keypad would be great. It will no doubt happen within the next couple of years too.
You're both misunderstanding my piece. I'm talking about the fact that many more future devices will have VGA video capture!
Having said that, it's a given that screen resolutions will probably rise as well, but not as quickly.

Well, the discussion begun with the pixelated videos when increased in size. I hope they don't stop at VGA and go further, maybe to HDTV? Technology makes huge steps nowadays.
Hi Steve, not misunderstanding merely also commenting on screen resolution. I realise it was concerning phone video capture and playback on a larger resolution device. I merely added that I look forward to both higher resolution capture and higher resolution phone displays.
