The full (paid) version of GoPro-Cineform Neo (as I have) does support alpha channels.
(A colleague initially thought otherwise – but that impression turned out to be based on info from old forum threads)

- David Newman, “9 months ago” (hence presumably November 20122)
- 4:4:4 and 4:4:4:4 (with alpha channel) requires at least CineForm Neo or as it is soon to be released under a new name “GoPro CineForm Studio Premium.”

- The DNxHD is good stuff, but Cineform seems to do a better job on a few levels (such as handling alpha channels and providing 422 from a 420 original video source… to name a few).
- Avid to AE? Dont’ use Cineform as an export. Use QT ref with DNxHD. Cineform, for me, is just a step to convert AVCHD to near lossless quality, then DNxHD ro Avid. Onve you are in Avid just export Qt Ref with DnxHD – no need to export to Cineform

- The free GoPro Cineform Studio program installs a light version of the Cineform codec (no 4:4:4 colorspace or alpha channel), but it is usable in any compatible program for both decoding and encoding. It’s maximum resolution, I believe, is 1920×1080 (the purchased Cineform codec can go higher).

- The GoPro CineForm Codec supports RAW camera formats such as Bayer patterns as well as RGB and YCrCb with an optional alpha channel and color difference sub-sampling.
