[QUOTE=stuartjjones;2262518]Thanks guys for the replies/questions. Below is a better description of the actual problem. I’ve aswered the questions / comments afterwards…
I burned a clip yesterday shot in my loft. I’ve just moved in so it’s a recording of how the place looks. When the image is just my face, everything is smooth and fine, but as I start to pan across the room, it then judders/jerks from time to time. The best way to describe is, it’s as if the image freezes for a split second / 5 or 6 frames and then skips to where the video has moved on to, thus missing out those 5 or 6 frames.
[B]You didn’t mention what brand and type of camera you have. Is it recording as an mpeg2 file, or is it recording as an .avi file. For example, camcorders that record directly to dvd, record in mpeg2.[/B]
However, when I first capture the video (using ULEAD or the native Panasonic tools - realtime through a USB Cable) the resultant AVI file is perfect. As in it plays perfectly through my PC (Windows Media Player) onto my monitor - no jerkiness atall. It does ocasionally occur but that’s related to some temprorary bottleneck on the PC, if I rewind and play again, it always clears itself. Interestingly, I can ‘hear’ this bottleneck as it coincides almost always with the PC making PC noises, which I assume is the HD doing some reading/writing.
[B]Problem 2 is that you are capturing via USB. That is not the best method. If you are capturing via usb, it is important that the camer is the only usb device that you have plugged in, and that you have all other non-essesential tasks on your pc shut down, including anti virus, antispam, etc… You can get good USB captures, but you have to make efforts to do so. Also make sure that you are capturing to a separate HD than the one that your windows and your capture software is installed on.[/B]
The big issue comes when I burn this AVI to DVD. When I play the burned disk back through the DVD on my PC, or through another to a TV, the jerkiness is there. It’s consistent - the image freezes then jerks at the same points. It’s as if this bottleneck has occured during the burning process and thus is now part of the DVD rcording itself.
[B]This could be due to reencoding an already encoded mpeg file, it could be the bitrate you are encoding at, it could be the media…[/B]
Have been investigating this for months now - driving me totally nuts!
Harley - I’m capturing the video through a USB cable/port. No the image/video (AVI) is fine after capture.
Eric - I’m using ULEAD Visual Studio 10 to both Capture edit & burn the DVD. (I’d use another rogram to burn the DVD but editing through Ulead leaves it in a proprietary Ulead format containing all the edit info, that I assume I can’t burn with say Nero.) PS - if the answer is that I need a new PC, then I will definitely go for it - what would you estimate the cost to be ?
Devilsclaw - Acceleration is Max and 3D rendering is on with settings at max. Yes it is a single core PC and I’m doing realtime capturing (through USB - I dont have Firewire port). I do have the video files on a separate drive to the s/w.[/QUOTE]
