Magic Mask Export Hang

hi I know this has come up before but does anyone have an up to date workaround for this issue?

i.e. magic mask tracking all works great in project but hangs indefinitely on export

any tips would be much appreciated
cheers

I have same issue when trying to render video in DR Studio 20.
I can't render video due to hanging with similar issue (and I don't think I even used Magic Mask in editing video).
Hopefully there will be a fix soon?

THE workaround, written dozens of time here and there : as the MM issue is it loses its specific cache (usually when quitting/relaunch), if you think everything is ok at the end of the tracking : right click > Render in Place.
No issue on export + you still can "open in TL" for any potential subsequent work on it.

Follow-up / Update:
Thanks to above post in this forum I was able to render a test duplicate version of my video.
I had previously removed attributes on this test version but hopefully this solution will work on original video also (without removing attributes).
As indicated, solution/workaround was to:
"Render in Place" all clips which had a "remnant" (the red line) of Magic Mask usage. One by one, I "Render in Place" these clips and after doing so to all (about 5 in my case) the entire video rendered successfully with no further errors.
Thanks all.

no unfortunately render in place causes other complications such as ignoring the alpha channel in the MM layer. at least that was my experience though no doubt there's a workaround for that too.

the workaround I found for the hanging thing is imperfect but straightforward at least. basically you render with the tracking disabled..which for whatever reason allows the intended tracking to happen at render time and all works out fine.

No, no further complication, you just come with another case here, so I will sort it out for you...
If your read me above, "if you think everything is ok at the end of the tracking" specifically meant :

1/ the track is ok, you checked it all along the clip, and you have added an alpha output to keep the matte above another clip under : make a compound clip of those 2 clips > Render in Place with any codec you like

2/ the track is ok, you checked it all along the clip, and you have added an alpha output to keep the matte ... alone, because you just want to export it for a subsequent use. Render in Place and use a codec which support alpha. I guess you're not on Mac so I keep the ProRes 4444 aside and suggest a DNxHQ with alpha (of h265 why not actually).

What you experienced just comes from no alpha support in the chosen codec, since I understand you're in case n°2
