Hello Everyone, I've often noticed Cinelerra incorrectly overlays layers with alpha transparency. The main issue I see is transparent areas of the bottom track getting incorrectly rendered when overlaid with partially transparent sections from tracks above.
...
After some deep debugging, I've tracked this issue down to the method used by Cinelerra to optimise the rendering of the bottom layer. Cinelerra seems to render the bottom layer using TRANSFER_REPLACE mode, which does make sense as there are no layers beneath it.
Good work!
Please let me know if you need any more info, patch files etc..
Yes please; more patches to the compositing pipeline in general. :-) For example correctly working alpha blending in RGB FLOAT mode, if you can figure it out. -- Herman Robak _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
