I understand that. lets say I *pay* for a h.264 codec from vendor.  the new format should be in some respects like QT, its a container for data. if I install a codec, then the data can be turned into picture. I'm not asking for explicit h264/5, but rather the option it can be in the container. having some built in standard codecs is great but what happens when some spiffy new codec shows up a year from now that we all might want to use ? if there is a codec component like QT, its an easy install. if its purely built into the libs for POM then adding it require an update of POM rather than just installing the codec into POM's codec component folder.

Dirac is an interesting codec to be sure and could be a nice solution if quality and speed is there.

for a very long time I never trusted apple not to either kill ProRes, come out with ProRes II, or in some way horribly screw it up. However, with the wide adoption of ProRes into cameras and even some PC based products its become its own monster. its hard to picture that at some point they don't release some spec for it or really license it more freely / cheaply including more options for PC that aren't limited to only specifc apps.

well h.264 is an interesting question. while often thought of as a very compressed long GOP format, it can be iframe, 10/12+ bits, 4:2:2 and 4:4:4 with a high enough  bit rate to be near lossless.

while the format you propose would like to directly avoid any patent encumbered technology, having it be open enough that a suitable h.264/5 codec could be added might well turn out to be a critical item in getting wider usage. another developer could bring in a suitable codec component.

ditto ProRes as odd as that might sound given its widespread use in cameras and recorders.


I'm afraid I'm going to be a stickler on the patent issues.  Theoretically a studio using H.264 in production might have to pay MPEG LA for the privilege of doing so.  Anyone making commercial software that uses H.264 definitely must pay MPEG LA.  I think that's a deal breaker that would prevent POM from gaining traction.

The ProRes situation is less clear.  There may not be any patent issues and Apple only warns against unauthorized implementations because it that are not given their seal of approval.  FFmpeg has a ProRes encoder/decoder, and it may be possible to duplicate it without violating the GPL license attached to it.

What I'm really hoping for is the Dirac codec works well enough that we forget all about H.264 and ProRes.
