Can you try apng or webm too? I suspect there is permission issue to write to the temp folder?

Checked with my pc, I can convert gif/apng/webm/webp without error.

I'm pretty sure the other conversion types are irrelevant to this. Anyway, tried APNG and WEBM and got the same result. Also updated to build 20210128, and still doesn't work

I'm pretty sure the other conversion types are irrelevant to this.

It is relevant, because it calling the same function, just different parameter for the encoder in FFMpeg.

Like I said before, most likely this is due to permission issue when it try to access the temp folder or some issue with your username/path. Is your username have special characters?

No.

then I have no idea as I cannot replicate your issue on my side.

Also check if the downloaded file is unblocked before extracting.

I've ran into the same issue. Turns out it's due to a bad/old version of ffmpeg and updating my ffmpeg version fixes it. The "cannot find file" error is just because ffmpeg didn't run successfully so the file wasn't produced and couldn't be moved.

i.e. was getting:

[AVFilterGraph @ 03417d80] No such filter: 'palettegen'
Error configuring filters.

May be worth adding a check on the return code of ffmpeg and printing the output if it fails to make it easier to look for issues. The current error logging also made me suspect it was due to permissions initially.
