Ciao Giuseppe, I did a test and I got a strange result. Same benchmark: 10 photos, 3 seconds each, no audio, crossfade transition, output at h264 1920x1080 16:9. Took a total of 2 minutes: the first two photos took 45 seconds each, at a speed similar to the old version, with low CPU usage with imagination at 100% and ffmpeg at 20%; then there was a "boost" in speed and the remaining 8 photos in less than a minute, with ffmpeg at 300% cpu and imagination at 50%..... Does it mean anything to you? Il...

Ciao Giuseppe, but how long does it take for you to encode 10 big pictures with h264 at 1920x1080 resolution? My system is a i5 2550k 3.4ghz, 8 gb ram, on Ubuntu 18.04 (but it was the same with previous 16.04). I still see the same from my original bug report: On my system using top I see that imagination is running at around 98% while ffmpeg at 20-30% (with 6 or 7 threads working at 5-6%), at around 5-6 fps. So I can conclude that imagination is feeding the pipe to ffmpeg too slowly... Il giorno...

Hi Giuseppe, just downloaded and built a snapshot from trunk. Tried to generate a x264 at 1080p with 10 photos with crossfade, no audio: more than 10 minutes... too slow...

Well.. I have no idea! But being a QT project I suppose it uses some Qxxx library,...

Yes same project on both, 10 photos with crossfade. See my first post.
