I guess I can conclude my research. Be warned the info may be incomplete, taken from what I could find on the Internet with Google, and from GIMP:



1) try saving the frames in OpenEXR (abbreviation unknown). It might be spelled as EXR. If you're given the option to choose bit width, take the highest. If you're given the option to compress, use lossless in this order of preference (don't use lossy compression even if you're given such option):

1.1) Zip (16 scanline blocks)

1.2) Zip (per scanline)

1.3) Run Length Encoding (RLE)

1.4) no compression

2) if [Open]EXR ain't available, go for TIFF (Tagged Image File Format). Might be spelled as TIF. Like [Open]EXR, TIFF is a lossless format that supports compression, but has a smaller feature arsenal, so [Open]EXR is recommended when nothing better is available. If you're given the option to compress, use lossless in this order of preference (don't use lossy compression even if you're given such option):

2.1) Deflate

2.2) LZW

2.3) Pack Bits

2.4) no compression

3) Then, in P$, make your animation and save/export to MP4. If you're given the option of choosing the video codec, there're only 2 of them, in order of preference: H.264 and AVC MPEG-4 .
