I am recording screencasts with ffmpeg(*), and editing them with kdenlive(**)
I have a problem: My videos often look much less sharp after rendering by kdenlive. I have to choose both a video profile and a rendering profile, and I am not sure I found the adequate ones.
First: Do I really have to choose profiles and such ? Is there a way to produce the cuts just keeping the resolution of the original (maybe with another software ?) ? I work with videos with the same resolution and sound, all the time
If not: What are the best profiles for me, considering quality ?
(*) ffmpeg -f x11grab -r 25 -s 800x450 -i :0.0+26,65 -f alsa -i plughw:1,0 -vcodec libx264 -crf 0 -preset ultrafast -acodec pcm_s16le video.mkv
(**) video profile 1024:576 PAL, rendering profile 1280:720 youtube, dowloaded from kdenlive itself
