Welcome to TVPaint Community forums !

The reason of this post, and the reason I came to know about new tvpaint(s) is because a need of mine, which is to record and export a whole drawing session.
I used to do this in aura by recording strokes, and then applying it to the animation frames. It worked for me, but it was still strenous as it didn't register color or brush changes, so I had to do all of them separately. And at any rate, I need to do this particular project in bigger than HD resolution, and aura doesn't work well like that.

The crucial point seems to be "larger than HD". You didn't tell the purpose of it, but I suggest to use the native recording option of Mac OS. It's pretty fast on a big machine and only limited by disk space. I recommend to stop recording and properly save the file every few minutes.

I am not quite sure to understand what you are trying to achieve, but you can use the drawing recorder.
