Premiere CC 2015 clips luma values to 0 and 100 IRE

It is not doing this in earlier versions of Premiere. I hope I don't have to downgrade to an earlier version. Does anyone know why it is doing this?

It behaves the same as before. What format are you using to test ?

Non native camera formats might get converted to RGB with a standard matrix and clipped. Passthough formats are treated as YUV and don't get clipped (mostly native footage, prores, v210, uyvy) . Also, the preview might be clipped but data is really there (recoverable superbrights/superdarks in those cases)

Uncompressed YUV. In previous versions, it would only do this when importing Lagarith, HuffYUV, UT. Now it seems to do this with the uncompressed too. I could just adjust it before it is clipped. Thanks.

There are different types of "uncompressed" YUV or planar arrangements. Functionally they are the same, but they are just arranged differently. But the problem is the receiving application might not handle all of them ideally

8bit 4:2:0 requires "IYUV" for passthrough

8bit 4:2:2 requires "UYVY" for passthrough

10bit 4:2:2 requires "v210" for passthrough

(by "passthough" I mean "don't get converted to RGB")

If you use something like vdub, 8bit 4:2:0 will normally be exported as "YV12" and get clipped by premiere and other NLE's - It's always been like that since at least CS4, probably earlier

Those are the "magical" fourcc's for other Windows based NLE's too (works on most Windows software like Vegas, Edius etc..., not just Adobe)
