Is it the ex1 or vimeo?
Okay, I've entered that third tier of hell: staring at sample videos of the few cameras I'm debating between AGAIN AND AGAIN. Before my girlfriend murders me, I need your help. In more than a few ex1 videos I've watched on vimeo, there seems to be a subtle frame jump every second or so. Is this an issue with the camera (the processor/memory filling up and jumping a little bit or the pulldown equation) or with vimeo's compression?
Answers strongly appreciated. thanks.

Definately Vimeo. None of my HD footage does that on the monitor in edit or on the videocam screen, but most of my larger file size Vimeo vids are jumpy.
Put away the local listing directory for battered mens' shelters, your girlfriend now owes you an apology which she may promptly prove by buying you either Snap-On brand tools or perhaps a wide angle EX1 conversion lens or carbon fiber Manfrotto tripod would suffice. ;)

Vimeo for sure. None of my ex1 footage has that oddity on exposureroom, while editing, viewed on camera, etc.

It's Vimeo, no worries with the camera.

Vimeo encodes to 720p24. This means that if you upload at 30fps (or 25fps in PAL land) Vimeo will do a very bad frame rate conversion.
I've complained to them about this but they insist most people don't have the bandwidth to play back 720p30. Personally I'd rather that they do that then drop frame they way they do which makes HD look bad UNLESS you actually shoot 24fps. In short everything HD not shot at 24fps exhibits the issue on Vimeo you're seeing. Good eye that you noticed it. I do too and have complained. I wish others would too especially since they now charge $60/year for those bad HD frame rate encodes. |

BTW, not sure what other cameras you're considering but the EX series really beats everything else in its price class and is fairly competitive against some more expensive cameras.

They seemed quite defensive about their decision too. They said they attempted 30fps briefly but they got lots of complaints. There are good and bad ways to convert p60 to p24. They're obviously doing a not so "intelligent" conversion (probably for the sake of speed).
They believe that many computers can't decode 720p30 On2VP6 fast enough. They claimed people were complaining about dropped frames . . . so instead they do a bad conversion to 24p for all of those shooting 25p, 30p, 50p, 60p, ensuring EVERYONE gets dropped frames. I don't want to be too derogatory but "nutty" is appropriate IMHO. As you might see elsewhere on DVinfo, YouTube is moving to 720p HD. YouTube Blog and YouTube Experiments with High-Quality Video - PC World and this thread on DVinfo http://www.dvinfo.net/conf/digital-v...ion-video.html They're still in the "experimental" stage. People have found that it's not just a wider screen in the blog but there's 720p playback and the belief is that it may well be 720p30 (and I'd guess 25p for those uploading PAL). Quote:
