So, the more advanced, space saving spec. of H264 that ATV3 supports... How much space can you save by encoding for it? (both DVD's and HD films)
Try a few short tests using the exact same source with each preset ... that will give you an idea. DVD's will have a greater savings than 1080p (due to the scaling mentioned above).
Probably not. the advanced opts in the atv 3 preset I pretty much took right from hi profile. atv3 and hi profile will do pretty much the exact same thing on a dvd, besides the decombing which is decomb fast for atv 3 so its a bit faster to encode.For DVDs I use "High Profile". Would the ATV3 preset be better? (I'm not worried about file size).
