[QUOTE="doveman, post: 1021969, member: 67412"] Fair enough, I thought the context made it clear enough. To be honest, so many programs just say MP4 Normal or MP4 High, I have trouble remembering that it means MPEG-4 part 10 / h.264 anyway ;) I realise it sounds like I want the best of all worlds but I suppose what I'm trying to get is just better than I've managed so far and what's good enough quality for my SDTV recordings might be unacceptable for some other material, so hopefully I'll be able to find that sweet spot where the files are as small as possible and take the least amount of time to make whilst still being acceptable quality. I'm trying the MKV Normal Quality profile now, which is using ffmpeg and these settings [CODE]ffmpeg-general=-threads 0 ffmpeg-video=-ss 3 -vf yadif=0:-1,hqdn3d -vcodec libx264 -b 1800k -x264opts me=hex:trellis=1:subq=8:partitions=all:8x8dct=1:ref=8:rc-lookahead=50:keyint=25:min-keyint=20:bframes=1:weightb=1:level=4.1:b-pyramid=normal:direct=auto:mixed-refs=1:deblock=-1,-1:no-fast-pskip=1:no-dct-decimate=1:b-adapt=0:threads=auto -map 0:a -map 0:v ffmpeg-audio=-acodec ac3 -ab 160k ffmpeg-audioac3=-acodec ac3 -ab 256k ffmpeg-ext=.mp4 ffmpeg-remuxto=.mkv ffmpeg-audiodelay=skip [/CODE] which is at least using most of the CPU but still is going to take about an hour. Next I'm going to try what is apparently the Universal profile from Handbrake [/QUOTE]
