Jerky playback

Hi
I have just rendered a 9.5 min "movie", on the template pal dv , and the play back is very jerky. The seperate hard drive where the files are stored was de-fragged last night, and there where no running programs in the background. The rendered "movie" was saved to disk, in the same seperate drive.

Here is the specs of my system.

Duel boot - win 98 games, Internet. Win 2000 video editing.
Gygabyte 7DXr mobo.
Athlon 1200.
256 DDr 2100 mem.
2 x 40gig ATA 100 7200rpm Hard drives. On IDE 1 and 2, no slave devices on either, DMA enabled.
Kyro 2 64meg video card.
Network card.
Fire wire card.

I have a feeling I may require more memory, but there may be a less expensive solution from someone on this forum. Thanks in advance.

Andrew

I don't have an answer but will be waiting for an answer. I too tried rendering a 4 minute video that had a combination of stills and video. The stills rendered fine but the video stuttered and had a ghosted image (very dizzying to watch). I used to think I only got the problem with slow-mo but this happened with regular motion video. I've tried rendering to NTSC, Sony DV and uncompressed AVI. All produced the same result.

I'm running a Sony Vaio
Windows 98 SE
600 Mhz Celeron,
256 MB RAM,
40 GB Hard Drive (7200 rpm) and a 60 GB Hard Drive (5400 rpm)
Fire wire card
Video Factory 2 Build 125.
Video was taken with a Sony TRV 320.

I never had this problem with version 1.

I don't think it could be a memory issue, Hendo, as I have vertually the same spec as you and I've never had this problem. I can't think what it could be though.

Hendo, just got a response from Sonic Foundry. Here's what they said:

It sounds like you may be having an interlacing problem. If you right
click on the problematic event, choose properties, then go to the media tab,
is the field ordering set to progressive or lower frame first? If you
change it to the opposite, does it make a difference when you render?

I tried it last night and it worked like a charm. I also saw a solution like this on the Vegas Video forum posted by Chienworks. Hope this helps you.

Hi Di and laz
Thanks for the response, I gave that a try, and I am not to sure if it worked. the jerky problem could be a slow shutter camcorder problem. The footage was indoors, without a light, and outdoors in foul weather. Further investigation will be needed.

When I started using Vegas Video, I also had problems with slow motion and was grateful that someone gave me the answer. Slow motion is one of the more obscure tools as there does not seem to be a clear answer in the 360 page manual. Al lest I haven’t discovered it.

I have spent some time looking this one up in the Forum search, however the reason why it is necessary to resample for slow motion is not explained.

I am grateful that I received a reply and wasn’t told to go search. I feel the Forum should be a friendly place where any question can be asked. After all you don’t have to answer if you are irritated by the question.
