I have done this in Shake with the apple animation codec. But that's an uncompressed rgba codec, so it taks up a lot of space.


AFAIK there's no real limit to say QT for supporting "odd" or "huge" resolutions.

Correct me if I'm wrong, but if you have an app that supports "weird" resolutions - like shake - you can export with wichever compression and make the file playback in qt.

You can use any CODEC which is not bound to some native dimensions. Video based CODECs like DV, DVCPRO, DVCPRO50, DVCPRO HD, HDV all have their native dimensions. Other CODECS like H.264, MPEG2, JPEG2000 etc. support any resolution. But the higher you go, the more likely your hardware will have problems keeping up.

gunleik: QuickTime is only a container format. It's not a CODEC.

What format does one use for download of video resolutions higher than 1920x1080? And what system do you need to play that back smoothly? This isn't a rhetorical question, I really don't know. Has anyone done that before?

Some codecs support greater than 1920x1080p like DiVX. But that wouldn't be a good representation of RED image quality. I'm hoping to see some more footage in various forms after NAB or even while NAB is happening. Hopefully, if the REDCODE codecs are available, even just for playback only, some of the early adopters and possibly the RED team as well can begin to share native format stuff.

So I guess we see what happens at NAB and with the release of the camera, eh?

The Apple Animation CODEC is NOT uncompressed. It's lossless though. It uses simple RLE (run length encoding).

1 - yes I know, dunno where I said otherwise -;)
2 - Right! Sorry for mixing up.

My main point, though - is that it's not impossible or hard to deliver 4k samples for us to see, if they want.

You just need a software that is resolutionindependent (like Shake)
And export to a resolution independent QT codec.

So basically:
The day they want us to see it, we can.

Sorry for misinterpreting that. :innocent: I just meant to say that it's the CODECs which limit the resolutions, and not QT.

No, it's no problem at all to produce and distribute such clips. But not many users have a 4K screen and enough hardware power to view them.
