Now that I have upgraded to a 4K TV I for the life of me can not successfully convert a file to stream from my library in iTunes to my AppleTV 4K.
BEST HANDBRAKE SETTINGS FOR 4K 1080P
I have used handbrake for awhile now doing monthly 1080P conversions. Otherwise, YouTube converts the unsupported colour spaces to BT.709 by mapping pixel values. AppleTV best 4K conversion settings to play from my computer library. Uses the specified value of colour primaries/matrix to set and override the unspecified one.Īfter the upload colour space standardisation, YouTube will check if BT.709 or BT.601 matches and passes through the colour space. The upload colour space mixes BT.601 and BT.709 colour primaries and matrix, and either primaries or matrix is unspecified. Uses the colour matrix to override the colour primaries and make them consistent.
The upload colour space mixes BT.601 and BT.709 colour primaries and matrix with specified values. The upload colour space has unknown or unspecified colour matrix and primaries.Īssumes BT.709 colour matrix and primaries. The upload colour space has unspecified TRC. So, using the first 15 minutes of Close Encounters of the Third Kind (4K) - because it's grainy and that's a good way to judge encoding resolution - here's what I found works best, at least for films shot on, well, film: CQ20 - h265 10-bit - VeryFast. In addition, YouTube may take the following actions to interpret the colour space values: When The output will be on the higher end of what is possible but you can tweak this by lowering the CRF value. These are the settings that I would recommend. Also keep in mind that each reencode, no matter the settings will reduce the quality. Or, BT.601 NTSC and PAL have functionally similar colour matrices and YouTube unifies them to BT.601 NTSC. Just a balance between quality, file size, and encoding time.
For example, BT.601 and BT.709 TRC are identical, and YouTube unifies them to BT.709. YouTube standardises functionally similar colour matrices and primaries before processing the video.
