Choppy render in NTSC DV....Help

Fortunatly this was just a test and not the final render. I rendered a 00:03:05 long music video to DV (NTSC Template) and the result was extremely choppy. I also did a test to .mpg (VCD) and .mpg (DVD) and they both came out fine. When I do go for the real render though I will want it to be NTSC DV. Any ideas?

AMD 1333 MHz
40 Gig 5400rpm OS drive
80 Gig 7200rpm Data drive
512 SDRAM
98SE

Thanks, -Shon

Try render "upper field first."

A DV render looks choppy during computer playback? That's fairly typical.

Choppy after you've printed back to DV? Something is configured incorrectly.

If you are outputting back to DV, you should always render LOWER field first.

This is not printed back to dv tape yet, just played through WMP. So you say that choppy playback is common? I've never expierenced it before with the exception of an uncompressed avi I rendered awhile back. Question, when I captured all the clips from the camera to DV why did they play smooth? This is the first video I am doing for someone other than myself, so i want to get everything right. Thanks, -Shon

Chances are, as you set up your render, that you selected 'uncompressed' rather than DV. Unless your machine is old and slow, or you are having IDE bus problems, you should ALWAYS be able to play DV rendered avi's in your Windows Media player with no stutter or choppiness. Many people make the error of selecting "uncompressed" rather than using the DV NTSC template provided by SOFO in the software. If you want to edit this template at all, the only changes you should ever make are to select "Best" as the render quality setting, and selecting "Resample all frames" in the same dialog box. Mess with anything else, you run a high risk for error.

I used the NTSC DV template unchanged from standard settings. I believe the standard setting is 'Good' and resample off. I will try another render and report back, Thanks for all the help. -Shon

Call it a fluke I guess. I rerendered and the new file played smooth. I must've had some setting off. Thanks for all the help. -Shon

Going back to playing .AVIs on Windows Media Player...should WMP(7.01)perform the same if you are running the file direct from the CD drive vs hard drive? The avi files were rendered using the NTSC DV template in VV. Having a problem with a few avi's not all....

SR_C did you ever figure out what caused your problem? RE-Render with any changes?

The Producer,

This particular problem has not reappeared as of yet, I never found the actual cause but then again, since it never happened again, I haven't looked very hard.

As far as playing video through your CD versus your hard drive, I have noticed a definite difference, especially if the avi is large. I am imagining it is the speed difference between the two but I will let one of our more expierenced friends answer the "why" part. -Shon

A bit more information on 2 AVI files that I am comparing when using the CD drive for playback.
#1 Works - 233,673KB 1,886 Frames, 3,713Kb/sec
#2 Stutters - 234,169KB 1,890 Frames, 3,713Kb/sec

Again both avi's rendered using the standard NTSC DV template.
What is causing one file to run but not the other??
