pleae advice..quicktime ...png compression

Hi guys,

Could someone tell me, which quicktime PNG compression setting is lossless, -- with filter setting set to none or set to best

Is this PNG compression quality as good as Animation codec?

Thanks.

Animation is an Uncompressed codec, and PNG is a comrpessed codec, so Animation should be better. If using PNG, you want to use the None filter.

Animation is a compressed codec as well.
The compression is lossless with quality set to 100%.
Animation is 8-bit.

PNG uses a lossless compression no matter which filtering
is used. The prefiltering is just a analyse of pixels for
optimizing the compression.
PNG ist 16-bit in general but the quicktime-codec seems
to be limited to 8-bit
