Description Mazin07 2021-03-04 02:22:22 UTC

SUMMARY

Any effects added to clips are ignored when using proxy clips.

STEPS TO REPRODUCE
1. Drag a video clip onto the timeline.
2. Add Edge Crop effect to the clip, either in the Project Bin or the clip on the timeline. Crop the image to half its size.
3. Enable proxy clips in the project.
4. Enable Proxy Clip for the video clip.

OBSERVED RESULT

After the proxy clip is generated, see that the project monitor no longer shows the result of the Edge Crop effect.

EXPECTED RESULT

Project Monitor should show the effects applied to the proxy.

SOFTWARE/OS VERSIONS

Using official Kdenlive 20.12.2 appimage build on Ubuntu

[can't figure out how to edit previous comment] 

What actually happens is that the effect get applied but the monitor doesnt refresh. If you move the cursor in the timeline it gets updated.

> If you move the cursor in the timeline it gets updated.

Unfortunately, moving the cursor on the timeline does *not* update my project monitor with the effect. Scrubbing the cursor shows the proxy clip without effects.

Ok, I now see your point, I think it is actually related to the switch in the project resolution.

Effects don't get updated upon resolution change, be it proxy or project resolution switching.
