View Full Version : cineform 50fps clip - 25fps render frame freezes

When rendering 720p 50fps cineform single file out to 720p 25fps in any delivery format there is lot's of frame freezes in the final video of approx 5 secs each (same in Vegas 8c and 9c). The same cineform file rendered out to 25fps in other NLE's are fine.

On the Vegas time line of the original cineform clip, each 2nd individual frame has frames from other parts of the video which also exhibit the problem. Seems cineform or vegas has mixed up some frames. This is a repeatable result (did it 3 times).

Any clues

Sounds like a question for Vegas support. As you pointed out the same file works in other NLEs. We don't do anything custom for Vegas, it is just using the VFW codec, and it makes no decisions about which frame to display (Vegas does.)

The same 50fps cineform transcoded file on the vegas timeline rendered out as avi lagarith 50fps works fine, it's only when it goes cineform - cineform the problem happens.

To explain it better.

Here's the workflow.

1.HMC152 720p 50fps file transcoded to cineform.
2. File imported into Vegas on 50fps timeline.
3. Few edits done then File rendered out to cineform 720p 50fps
4. File imported back into vegas rendered out as 720p 25fps m2t.

Step 3 is where the frames are scattered in places and causes freezing when processed in step 4.

Is this still Vegas problem David?

Thanks

Have support try it, but I can't see how we could do that.

Fair enough, my workaround is to not use cineform neoscene to render out but use the free Lagarith codec instead within Vegas. Defeats buying cineform in the first place for multiple renders.

I'll keep trying it with other clips.

Contact support, that way you can know it is a local PC, a Vegas or CineForm issue. Please do that.
