warp stabilizer causing export to Fail

[Archer32838230e3ix]

When trying to export a 10 min sequence, 4k video, about 10-20 small clips with warp stabilizer effect applied. The export fails to encode / export fails. Im exporting at a bitrate of about 15, stabilizing the videos only about 1-3% smoothness. It seems I can export successfully if I remove the warp stabilization, or break the sequence down into 1-2 minute segments but thats not convenient. My Project has also been freezing and crashing as well. I tried re-exporting the individual source files at a lower bit rate. Issue persisted. Files are not corrupted. 

Please help

The issue happens both on my m1 pro macbook pro and also my Nvidia RTX3080 with i9 processor

Warp is by far the heaviest processing load effect you can possibly use. So you are loading your CPU with a ton there.

Next, the way it works is two separate steps ... first, it analyzes a clip, then it applies the effect to the clip. Both are heavy hitters.

So with many Warp instances to apply, plus doing the encode to new media simultaneously! ... it can fritz the processing. Processing order issues and whatnot.

So it might be wise to first go through and apply Warp, and analyze everything, then do a full render & replace, then export ... as doing the r&r step 'bakes' the effect in as new media clips.

The exports work a ton faster and always reliably then.

Just a practical solution.

Hi Archer32838230e3ix,

Sorry to hear about this. As R Neil Haugen suggested, warp stabilizer can be quite intensive to process, especially if multiple instances are applied simultaneously. Is it freezing at any specific timecode/clip, or is it random? Also, are you able to render the sequence (Sequence > Render In to Out)?

Thanks,

Sumeet
