PLEASE HELP - Compiling Error Warp Stabilizer

[clueless2090]

Please help... I cannot export my video because I keep getting this error (see attachment). Previously I always edited on a 25fps timeline for 25fps clips, but recently I switched to 29.97fps as I started shooting 29.97fps. Also worth noting that in the middle of editing process, I switched the sequence setting from 25fps to 29.97fps, and then I reanalyzed the warp stabilizer for the clips.

Also it seems that when I trim/extend the problematic clip, the export will continue, but I keep getting this error for the other clips. It's simply taxing to just cut/extend the problematic clips and trying to reexport every time. Anyone knows how to solve this? Please don't let countless hours of my work go to waste. Thank you.

I take it the warp is on short bits of clip?

I always export out the warped clip and add that to my timeline. (Right-Click) Render and Replace the clip with something like a ProResLT or even Proxy if disk space is limited. Then you wont have to wait on the exports to do the warp.

Is there any simpler method to fix this? I noticed that the warp created a black frame at the end of various clips. I don't want to redo all my works.

You didn't mention this... "I take it the warp is on short bits of clip?"

What's the longest clip you are warping?

[clueless2090]

Yes, the warp is on short bits of clips (4-15 secs) that now form 8 minutes.

Did you try exporting using "Software only" renderer, instead of Hardware accelerated?

[clueless2090]

No, but with that it takes 8 hours, and I think the problem is related to the fact that warp stabilizer suddenly created black frames at the end of certain clips.

Ok, let's try something. Select all the videos on the timeline, right click and nest.

Double click on the nest to open it.

Go to sequence settings and revert it to 29.97fps.

Re-analyse the stabilizer, and see if this gets rid of the black frames.

If so, go back to your original timeline (25fps) and try exporting.

Let us know if this helps.

It seems that the black frame is removed through this weird workflow:

1) Render and replace the problematic clip

2) Once done, I was told to reanalyze, but the analyze button is disabled, so I undid the rendering

3) Somehow, when I analyzed again, the black frame totally disappeared

The nesting approach did not seem to work

[clueless2090]

OK I found a solution, just as a reference for other people who might encounter a similar situation.

What I did was:

1) I removed all attributes from the clip except Lumetri Color

2) I rendered the clip (sequence, render selection)

3) Then I applied Warp Stabilizer to the rendered clip. The black frame was totally gone.
