Higher bit rate file smaller than lower bit rate file?

Post by Starhawk »

Ok, Im scratching my head on this one. Why would a file with a higher total bit rate (as reported my OSX) be smaller in file size than another file with a lower total bit rate?

Im re-encoding Season 1 of the Simpsons and Im seeing this when comparing to episodes I encoded last July. Does this have anything do to with the difference in the way Leopard and Snow Leopard report file sizes?

Im using completely different settings, lowered the RF from 20.75 to 20, still included the AC3 passthu and 160kpbs AAC file, but regardless, I thought the older file with the larger bit rate would be bigger. :?

Re: Higher bit rate file smaller than lower bit rate file?

Post by JohnAStebbins »

They are indeed different in size according to the log. i'm not sure why. The first had a higher quality factor and higher storage res. I would have thought it would be larger.

Edit: on a third look, the second has significantly higher PSNR. Changes in x264 must have skewed the quality curve for this source a bit.

Ok, so looking at the different bit rates here for the video track, AAC track, and AC3 track. On the July encode, they all add up to match what OSX reports as the "Total Bit Rate" of 1,953, but if you add up the tracks for the encode today, we should get 2,347, but OSX is reporting it as 1,901? So it looks like OSX is ignoring the AC3 bits. Does that sound like what is going on?

Totally guessing here, but I think it might be from me using x264's Animation tune on a source that's not very clean plus using lower RF.

Post by Deleted User 11865 »

Aside from the fact that you're using a different rate factor, different x264 settings, decomb settings, anamorphic settings, one encode is also pre-mbtree, so there's plenty of reasons for bitrate to differ greatly ;-)

But regarding your question as to why OS X reports a lower bitrate for the larger encode, it does seem to be ignoring the bitrate of the AC3 track in the newer, larger file for some reason (no logical explanation comes to mind).
