Welcome to TVPaint Community forums !

Going to try and explain this as clearly as possible:

So, I'm in the final stages of rendering my animated short to individual ProRes video files. I've broken the 8min short up into 5 separate projects to make it manageable.
I noticed that some clips require more time in the beginning as I sometimes crossfade shots in Final Cut Pro, so in TVPaint, instead of selecting all of the layers in a clip and dragging them further right in the timeline to 'create more empty time in the beginning', I dragged the handle of one of the layers left to make more time before the starting point of the clip, and moved the new 'MARK IN' point a lot more left in the timeline.

This didn't seem to be a problem when I export the whole project as one video file, BUT when I render individual clips as video files, the new IN and OUT aren't respected at all and I'm getting all that new stuff I made before the new IN point is not being included in the exports of individual clips.

I hope that explains it well enough - I basically tried to extend the intros of some clips, and did this by dragging a layer's handle left to move the new IN point left before the new starting point. When rendering the whole project, the new IN and OUT points of the clips work fine, but not when rendering the individual clips.

Curious if anyone knows about this bug please, and if there's any fix (besides reworking all the clips I've done this to)

[EDIT: It seems to have problems in general when there's exposures before the IN point I think, I can extend the OUT point but when trying to export the individual clip, it doesn't seem to pick up the new change]

So eg here, even though you can see I've set the OUT point to 7 seconds in the timeline, for some reason TVPaint 'Export Footage - Clip: Display' won't go past an old OUT point of 1:18 seconds, and I'm not sure how to tell it that there's a new OUT point.
Even if I type in the numbers 00:07:00 manually, the field still defaults back to 00:01:18

[EDIT: OK, I've had some luck dragging the background layer handle to a full 7 seconds and not using HOLD to make the background last indefinitely, the individual clip export doesn't seem to like empty space but seems to respect frames that have at least one exposure showing I think. Still haven't solved how to get the clip export view to pick up my earlier IN point though, but could copy and paste layers of affected clips to a new clip in the meantime as one solution]

Ok, I think I know why this is happening - if you drag a layer's handle left past 00:00:01, the time turns into something (23:59:59:23 ) that you can't even physically type into the export field lol.



D'oh. Gonna rework these clips to start at 00:00:01

The solution was to drag anything I wanted rendered over to the right, and not before 00:00:01 as it's not possible to render anything before then in CLIP export. Curiously, CLIP EXPORT will disregard any HOLD or LOOP settings, and some kind of layer MUST be present right up until the OUT point. Similarly, CLIP EXPORT will disregard a clip's IN point, this needs to be set manually on render. These issues do not exist when rendering a whole project - when rendering a full PROJECT, Clips IN and OUT points are respected, and clips will render even if they consist of HOLD or LOOP frames. Just some idiosyncrasies of TVPaint. Kewl.
