Re: [Avid-L2] Re: Avid & jpeg2000 - More questions (& anomalies)

Mpeg II licences will be free within a year or so, close to all patents have lapsed, and the remaining ones last not so long.

A licence for Mpeg II costs close to nothing on patent fees (but the price of course depends on the one you buy it from...)

And for QT on win, that's about QT in a webbrowser, NOT qt player!

But besides that, you don't need QT player to play QT movies, a lot of other players can do this just fine.

H264 can be better than MpegII, but the opposite is also true. It highly depends on the encoder and the encoding settings.

Over here, MpegII is standard for broadcast.

Sounds like you're not looking for an open standard but a Mac standard.

If its Mac compatibility then just go with Prores.

And Macs only come some codec support not all. Even MPEG2 has to be purchased and installed on a Mac for MPEG2 playback.

Likewise you have to install the Avid codecs (which are free) to get support. But you can install them on any Mac or PC from free.

We can no longer install QuickTime on PCs and get ProRes support as Apple no longer support QT on PCs and the last PC QT version has security issues.

And yes a JPEG compressed file would expect to be smaller than a ProRes one. It's a more advanced sophisticated codec. Its not the file size that determines quality.

An H264 file is smaller than an MPEG2 but better quality.
