[HELP] FFMPEG Help - x265 HDR HLG Encoding from MXF
Quote:-c:a aac -b:a 320k: libfaac is outdated.. (?) and I need CBR @ 320k
not necessarily, but libfaac isn't included in ffmpeg unless you compile it youself due to license restrictions.

Quote:-ss 4.08: 4 seconds and 2 frames offset for video (I guess because of 50fps to 25fps conversion)
Nope, frame rate change doesn't change offset, but encoding to aac might.

Quote:One more thing: does -ss affect the encoding speed? I just rendered a small part, but it seems to be much slower (encoded 125 frames in 20.06s (6.23 fps) VS. encoded 227 frames in 22.63s (10.03 fps)).
It should not, but the start will take a lot longer if your source doesn't have an index since then the first few seconds need to be decoded until the selected time is reached.
