Hi, unfortunately, I had to report no visible effect :( I reencoded all my test videos, I mean I reencoded all *outputs* from Kdenlive not the sources, through ffmpeg with suggested attribute, but problem remains.
All the same: all videos from Avidemux are played OK on any DVD player and PC (high quality, very smooth) but everything I reencode through Kdenlive gives me the same flickering with fuzzy jumping edges playback in DVD player. PC playback is bearable, lets say 'good', but not so smooth anyway. I checked my testing video DVD on another DVD player, high quality Sony brand box this time - and the same result. The clip from Avidemux is fine, those from Kdenlive are virtually unwatchable. So DVD player is out of suspiction. I use QDVDAuthor for creating video DVD and K3B for burning. Both applications are out of suspicion too because of the same reason: The clip direcly from Avidemux is fine, those from Kdenlive are virtually unwatchable. Just a notice: Source video has around 7MB Output video from Kdenlive has around 10 MB so there is like 30% increase in size. Isn't the bitrate quality in DVD export profile set too high? Output video from Kdenlive reencoded again using ffmpeg -target dvd has around 10 MB too. Avidemux uses ffmpeg or mencoder in background? Hmm, there could be some catch too. I'm still not giving up. I try some experiments again. I try to compile Kdenlive & comp. from svn/cvs. I can try to put target=dvd directly to Kdenlive libavformat parameters in export profile. I will keep you informed.
