may be it just encodes _very_ slowly? like 20 min for ~1 min video with 320x200 sized frame... single-threaded...
True: 7:43 min for 9 seconds of video; single thread; freeze (temporarily) to 10% and then to 95%.
hm, strange.. can you try to debug this a bit (for example was it working in previous appimages/tagged releases?)
The video transitions that don't work are: BandWipe; Wipe; Dissolve; Shape Wipe and IrisSquare. They don't work in git, in the latest appimage or even in appimage 20201030. No error on the terminal.
well, in x265-10 bit encode we still see message about encoding 7499 (not 7500) frames (from x265 library itself) . I hope this is bug in reporting, but can you add some specific image/effect at this very end frame and try to play resulted encode with, say, ffplay? (i think it will freeze last frame on display)
Yes; trying a render with x265-10-bit and playing back the file obtained with ffply I get a freeze in the last frame with the last line of the terminal (indicating the momentary value: 19.46 A-V ...) that keeps increasing the number to infinity and I have to stop with ctrl+c. The same thing happens with DNxHR and x264. See image.
