FFmpeg using png with tranparency and exclusion blending mode
27 août 2016, par moorejI’m trying to use the exclusion blending mode to blend together a video and a png with transparency. I’ve looked around quite a bit but I can’t find a solution that works for me. Here’s the ffmpeg command :
ffmpeg -i movie.mkv -i text_white_bg_trans.png -filter_complex\
"[1:v]setsar=sar=1,format=rgba[txt]; [0:v]format=rgba[mo]; [mo][txt]blend=all_mode='exclusion'" out_exclusion.mkvEdit : and the console output :

[libx264 @ 0x7fb10a01e200] kb/s:3830.94Edit : Here’s a frame from the output.
The output video is B&W rather than the original color (not sure why). The rectangle in the image is located where there is a block of text on a png with a transparent background. The png is the same size as the video.I’m expecting something more like this :
@Mulvya suggestion fixed the issue with color but I’m still seeing some problems with transparency being handled. I’m attaching a few different images below that each create different problems. All created in Photoshop CC (therein may lie the problem).
A transparent background with a separate text layer that is then exported by Save->png, Photoshop appears to merge these two layers but differently than when "merge layers" is chosen before export. The exported image looks like the B&W image I posted above but with color.
The in the second I merge the layers before exporting. It appears the entire image is treated as white.
In the third I draw "hello" on a transparent layer with a "soft" brush using different grays then export. Transparent areas are rendered as white, gray or translucent areas opaque or with a strange dithering "effect."
It seems I’m moving outside the realm of StackOverflow, but I’m not sure where this post would be better suited.
