Welcome to TVPaint Community forums !

Once I was checking a complete computer setup (hardware) for 20 min because I didnt see the "sound" button.

There's another small button in the playback controls right between loop and framerate, which does "play with camera view".

I have that often in v10. Didn't know it persisted in v11.

And the longer I use it, the more I invent special workflows around it to use it to my advantage. If only this would be scriptable ... (with the ability to store away the action in case)

OK. Step by step. Is it black areas on white? Use Scan Cleaner on all frames. Is it black areas on transparent? Good. Switch on "preserve transparency". Drag a rectangle over the first frame. All black should be coloured now. Is it? Good. Undo. Select all frames. Hit "Enter", that's "re-apply". All ...

Take care to upload that file to wetransfer.com so you could send it to TVP staff, they often can save it. Does TVP crash if you just create a new file and sa...

Out of space: you mean hard disk space? (Last time I had this problem was in the 90's ...)
Do you have more than one volume? An external drive?
If only 1 volume: see that you can have 20% free space.

Of course. Just set the "smooth" range before drawing the selection (or use the magic wand). The nice thing is that you can add or subtract from a selection, and change this parameter each time.

Does Adobe own rights to any image created in PS? No. Same is true to any other imaging or painting software.

Yes.

Working on Mac, I've noticed that PNG is definitely slower in writing than other formats, in TVP as well as in PS.

Play around with colour adjustment and see what you get.

La manière habituelle: la taille d'impression en pouces x la résolution souhaitée vous donne les dimensions du projet en pixels.

The usual way: printing size in inches x desired resolution gives you the project dimenions in pixels.
