Description darwish5528 2021-12-18 12:14:12 UTC
before this, rotoscoping is working properly untill I make it 100% to 120% speed while the effect (rotoscoping) with all the keyframe there and then adjusting the keyframe (on rotoscoping) back. It's working properly within a few second then the effect is not working and it's stuck on the upper corner of the video. I'll tried copy the effect, delete the effect and paste it back but it's still there. Please fix this as soon as possible, I've been working for this project for 3 days with 70 clips. Windows 11 kdenlive 21.12.0

Is there another clip in the timeline which interfere with rotoscope? Hide V1 to see if this clip interferes with V2.

I already hide it but it's still the same.

I think I am affected by this bug as well. Am I?

I first posted a comments in Bug 437700 Rotoscopy offset before finding this bug and reporter Comment 0 suggesting the issue might be linked to increased speed of the clip causing rotoscoping wrong calculation and offset!

As per my Bug 437700 Comment 5 and its attachment for reference https://bugs.kde.org/attachment.cgi?id=146397 my originally created rotoscoping path on accelerated clip stop working at some point so I had to offset them horizontally off the shape edges (see attachment) to fix the effect issues encounter like shape partially disappearing during preview and render especially when it was moving location.

The clip I apply rotoscoping is effectively accelerated in my case.
