quicktime’s jpeg2000 at 100% is also 8 bit lossless, alpha support, like animation but 1/2 the size.
Its standard is used in digital projection equipment.

There are also other kinds like jpeg2000 sequencing that can go 10 bit or higher, but many techies and I agree that Tiff is best for image sequencing. It’s thread, multi-proc safe, and with lzw compression off, is the smallest size for lossless.
