Dammit, sorry I just react : do you mean that TVPaint completes the export, but then the exported file cannot be played ?D.T.

(FFMpeg .MP4 export to MPEG-4 or H.264 is working correctly; it is only the Lossless option that is not working).

When I try to export to FFMpeg .MP4 Lossless when I attempt to open the file I get an error message:
"The Movie Could Not Be Opened. The movie contains some invalid data".

Yes, it used to work before. And other MP4 files play in Quicktime player. (including MP4 exported from TVPaint as FFMpeg Compressed H.264 RGB-RGBA and Compressed MPEG4 RGB ; only Lossless PNG RGB-RGBA does not open in Quicktime player).Xavier wrote: ↑22 Mar 2021, 14:18 Yes, indeed there was a confusion with another issue we had : on Windows, the FFmpeg plugin wasn't able to export to MP4 using the lossless PNG codec.
Anyway since the file opens in VLC and in other alternative players, then the issue may be related to the Quicktime Player
Or are you saying that it used to work before ?
I meant MP4 files always worked before with Quicktime player, so I don't think it's an issue with Quicktime. (but I don't know for sure if I've every played FFMpeg Lossless MP4 with Quicktime player before ... I don't usually check the codec unless there is some problem)
Export to MOV (FFMpeg) Lossless works fine . It opens in Quicktime , VLC , Elmedia , MPEG Streamclip players.
I think that information should be added to the section of the User Manual covering Export options so Mac users are aware they can't use the PNG Lossless MP4 option to open in Quicktime , which is still the default video player for Mac. (Mac users can use VLC player instead, although VLC still lacks the ability to step through video frame by frame , forwards and backwards. You can step through frame by frame using the E key , but only going forward , not backward. This is rather annoying about VLC.
Sure, I agree with youD.T. Nethery wrote: ↑22 Mar 2021, 18:06 I think that information should be added to the section of the User Manual covering Export options so Mac users are aware they can't use the PNG Lossless MP4 option to open in Quicktime , which is still the default video player for Mac.
You can try using djv view for playback which is 100% free(https://darbyjohnston.github.io/DJV/)D.T.

Elmedia Video Player allows for stepping through frames forward and backward. The free version of Elmedia works fine , although there is a "Pro" version for $19.95 U.S. that has more features .)
