Parts of video "corrupted" after exporting project

Help/How To
1

Hi,

I’m trying to export a project and I have a part in the sequence where two clips are side by side then using the “size, rotate and position” filter I am “animating” transitioning one clip from taking up 50% of the screen to 100%.

I have two versions of Shotcut available as suggested previously, my original version which is part of the Arch Linux distro packages, and the portable binary version downloaded from the website.

If I use my original version the project will ‘export’ but I am seeing this:

mpv-shot0003
mpv-shot00031920×1080 349 KB

The portable binary just segfaulted on me with 1 hour to go of the 5 hours it is taking to render and attempting to restart the log shows this:

mlt_repository_init: failed to dlopen /vr/home/kaya/Downloads/Shotcut/Shotcut.app/lib/mlt-7/libmltsox.so

The actual footage is fine when viewing in the player:

What is going on here and why is the video clip that has been resized to 30% using keyframes to bring it to 100% not actually exporting properly?

Is there something I could try to enable to export the session properly?

I am using the “hardware encoder” if that is the issue and do have some GPU based filters???

Did a quick experiment and can confirm that it’s the “Size, Position, and Rotate” filter causing issues…

I will try the hardware “Size and Position” filter instead and see if that helps…

The “Size, Position, and Rotate” filter also had distorted the image and made it go funny by ghosting and doing other weird things to it

If GPU Effects is on you should use the GPU version of a filter as much as possible.
