mchesnayWed Apr 27, 2011 1:55 pmJust wondering, why do you use this preset over Autodesk's?
smalkieWed Apr 27, 2011 3:46 pmThe Autodesk-supplied "H.264 (High)" is a good general-use encoding preset, and we used it quite a bit.
However, since the vast majority of our work is less than minute in a length, often time less than 35 seconds, we wanted to bump up some of the ffmpeg options to a higher quality, more CPU-intensive setting. The idea being that we could take a bit more of hit on encoding times since our encoding source durations are so small.

After a bunch of testing we found that 1) switching to umh instead of hex, 2) adding the 8x8 I-frame partitions + the dct8x8 option, and 3) bumping up the -subq to 9 really added a lot of quality without too much more of a time hit.

We also hard-coded the output width and CRF purely to have one less setting for our Assistant Editors to have to worry about and/or possibly mess up.

Hope this helps!
smalkieWed Apr 27, 2011 3:51 pmI've also experimented with re-compiling FFMPEG to include wmv2 / wmav2 as well as libvpx / libvorbis for making WMVs and WebM content, but so far it hasn't gone well. FFMPEG is just a beast to get working right, which is why we're so happy with WiretapCentral !

mchesnayFri Apr 29, 2011 9:00 amAlexei, have tried posting your preset question to the Area forums?

A question such as yours is best asked in a forum setting :)
