Converting Alpha .mov to H264 mp4?
on Oct 13, 2016 at 3:30:20 pm

Hi all,

I'm having to send a few Intro to a client of mine but my problem is the size. Each of the 9 Intros are 1.7 GiB Big. (First Picture)


But I would Like to export it to a Mp4/H264 or any other small file but I need to keep the files alphal?

I don't know of any heavily compressed format than maintains the alpha at a "small" file size.
List of Video Formats with Alpha

VP6 (FLV) supports Alpha but you're not going to want to do post production work with it. Since web browsers have moved to direct HTML player support it's not used much on the web theses days.
I'm not sure how big video PNG with alpha would be.

I'm not sure why you'd want to try anything not widely supported. Even a free DropBox or iCloud account can support up to 5GB. You can send the files one or two at a time.

Personally I'd use ProRes 4444

Hey Craig Seeman,

Unfortunately I live in South Africa :/ Where our internet speeds aren't the best (1Mb up, 2mb down) so uploading 5Gib of data would take ridiculously long. I'll Give ProRes 4444 a try ?

Depending on the need you could mail the files on Hard Drive, SSD drive (more expensive but more durable for mail) or SD cards (small enough to fit in a standard envelope).
