Use avif as openexr alternative for hdr movie maker

[octanejohn]

webp, avi, png, jpeg doesnt support hdr

use avif because openexr is bigger size, longer encode, limited support(browsers, editors, viewers, hardware acceleration, ect)

Unfortunately, AVIF's lossless compression is poor (it's slow and inefficient even compared to PNG), so I'd prefer having support for writing PNGs with high color depth instead. Remember that lossless output is preferable for advanced use cases, so I wouldn't opt for a format that is only good at lossy compression.
