AVI Putput is very choppy

Hi all... Quick (hopefully) question...

I recently purchased a video camera and am using Videofactory 1.0 (please dont say upgrade to 2.0 because this "should" work regardless of what version i have)

Anyway I can capture just fine.. no frames are dropped... nothing... everything is perfect..
I go ahead and edit the video and some text.. and then i render ( i render as NTSC DV compressed and Ive done it uncompressed) out to avi file..

the avi file becomes SOOOO choppy. However if I use Ulead 5.0 and add text and edit video and output it to AVI its perfect no choppiness (so I know the video card, the firewire, the hard drive is fine) does anyone have any thoughts?

Ive tried saving it in different compression modes using "No compression" to "NTSC DV" compression..

and sometimes... just sometimes.. after i render a video the avi format is perfect.. but as soon as I reboot my computer and execute the avi its choppy...

I have a 60gb hard drive dedicated to just VIDEO, I have 756 RAM and i run a 700mhz Athalon chip.. updated video drivers/motherboard drivers.. everything is running perfectly.. i have defragged the hardrive.. please if anyone can help its for my grandmothers funeral and would like to get this out to my family (FYI, Im outputting it to AVI so I can output it to video tape)

I believe since i have used other software and it works perfect that the camera and the computer is fine, it must be somewhere during the rendering process.. i have rendered as default as well as played with the compression and it all comes down to the same thing..

please help!

Does your project properties match your capture size? I found this out when I captured video at 352x240 and my project was set to 720x240 and the video looked jerky. All I needed to do was change the project properties to match the capture settings. Or you could create a new project and match the properties of what you've captured.

hope this helps.

1. Make sure DMA is enabled for your hard disk(s). (Search for DMA in this forum to see how to do this).

2. If the video is chopyy when playing in VideoFactory, go to "Options," "Preferences," and make sure that "Always Use Sonic Foundry DV Reader" is checked.

i had a strange occurence, more than once.
i edited about 10 mins of video. i noticed that on the timeline, my video viewed on the viewscreen became jerky, strobelike, especially noticeble on camera pans. the action took on a slight surreal appearance. this only affected a few minutes of video, then after a certain point, it cleared up. the rendered dv had the same appearance as what i saw in the viewscreen. as mentioned, this problem only started somewhere in the middle of the project, contined a few minutes, then cleared up.

i did many tests to see what was going on. i looked at the same affected scenes in the raw capture. it was clean. i took the same raw capture to the timeline as a new project..clean! i even re-added the affected scenes at the end of the project, and they were clean, though in the middle of the timeline they were choppy.

weird! well, i found that when i removed a transition right at the point where the choppiness started, the affected scene now was good. i then put the transition back, and the affected area was still clean, BUT the choppiness now moved further down the timeline to previously good scenes. confused??

doing more tests, i disabled snap which i usually leave on. i checked the timline some more. and now the entire timeline, and of course rendered dv is good, nice and smooth. i'm not sure what caused this strange effect, it seemed to be some sort of bug. if it happens on future editing, ill do more tests.

anyway, i dont know if this is whats happening in your case. maybe it will help.

good luck,
joe s
