Prores 4444

[Angelo Mike]

Not that I’m aware of. Vegas can indeed render to 422, though, both with an Avid plugin (that’s free to download) or in one of the profiles for mpeg2 rendering.

Vegas can usually only render with alpha channel (the fourth “4”) to uncompressed or uncompressed-ish formats. That’s because you rarely want an alpha channel with any lossless compression, as you can imagine. I use this all the time for animation projects.

Some add-ons allow 4:4:4:4 rendering. Cineform does, and I think Avid DNxHD as well. For most project, though, the alpha layer is simply meaningless.

In theory Apple gear can render ProRes, that’s a proprietary Apple format. The license it out to some hardware companies. But I recently came across this program: 5DtoRGB (https://rarevision.com/rarevision.com/5dtorgb/index.php). It’s a freebie, and claims to produce proper Apple ProRes from an AVC input file (at least… maybe other formats, haven’t tried it). I have used it occasionally to put AVC into DNxHD directly. The author wrote this primarily to convert HDSLR video (Canon 5D, thus the name) into “something else”. I think this using the ffmpeg engine and ProRes CODECs developed in the open source community for libavcodec (the thing VLC uses to decode everything without the need to install Windows CODECs, and much of the basis for video on Linux).

I have not actually had the need for ProRes, so I don’t know how well this works. But something to try, it you must have ProRes.
