PNG sequence… will not be transparent PNGs, I think?
Have to figure out what blend mode to use in the video editor… + the Hype scene background colour, so that the overlay with the PNG sequence does not affect the background colour of the 3D animation (video)… or any other colour…
I have tried this before, but never associated transparent background in exports with the Hype document setting, although aware of this Hype document setting. Perhaps a 'transparent background' checkbox should be present in the export dialoge for those export formats that supports it.
Worked perfect with a PNG sequence in Premiere Pro, with transparent background, on top of the 3D-rendered video.
The change will be in the next bugfix release we do, though since we just pushed out a 4.0.6 it might be a bit since there's nothing else in the 4.0.x pipeline currently. Feel free to continue to use the build I sent you. (It does expire in 10 weeks but I'm guessing will make its way into an official release before then)
Hype becomes a good candidate for complex compositions compared with e.g. After Effects — if Hype animations with video clips, elements with blend modes… etc can be handled within Hype and exported as video, with good quality. (Been working with a video project the last weeks.)
To add something more to the 4.0.x pipeline, within this specific area; can the export time be shortened somehow, somewhat?
I was thinking the same thing about render times while working on this problem . In fact, part of the fix to this bug will make rendering take longer.
Unfortunately there's not a magic bullet to shorten the time; because Hype uses WebKit to render each frame we do not get detailed information when the frame is fully ready. This means we need to introduce arbitrary delays; in fact we detect there is a video on the scene we have a minimum .2 second delay per frame to insure the video changes as seeks can sometimes take a while.
