If we could get that to work then transcoding would not be necessary at all (when using adobe products). CoreAVC is fast enough for realtime playback, trouble is that the NLE won't use it.

That's interesting. But what happens if you open a re-wrapped file in AE or Premiere? Does it use CoreAVC in that case? And if so, is it fast and smooth on the timeline? I switched from Premiere Pro to Vegas many moons ago...

I corrected the error in my post. I just assumed that it worked since I use CS3 & Cineform. What's really interesting is that people that have tried using AviSynth to force Premiere to use the DirectShow codec with the highest file merit still can't get it to work.

I'd be curious to know whether just changing the extension to .MP4 would work in this case if QT was not installed?

It *might* work but if the software is really strict with respect to the MP4 standards, it should fail to open it as it contains an audio stream ('sowt') that's illegal according to the MP4 standard. That's why you have to re-encode the audio as AAC during the re-wrap process I devised.

After some searching I found that to enable MP4 support Premiere needs to be updated to 3.02. I will try tomorrow and see if it works. Right now my version does not support the MP4 container at all.

I can't see spending that much just to fix something (colorspace glitches) that we shouldn't have to worry about in the first place.

Hmm So I have Cineform HDV (the stand alone application, not the one that came with Vegas) If you're able to render it to the cineform codec from within vegas, why can't I use NeoHDV's HDLink and render my 5D2 files?

who said you couldn't do that? have you tried it? I think it should work.

NLE with Canon EOS 5D MkII
 
Hi All,
I've been messing around trying out the limits of the camera and have noticed that as mentioned, direct dragging to the timeline seems to lose some of the dynamic range. I have tried this in Vegas 8 Pro with 32 bit option selected and it seems better. The BEST quick results have been to use the Windows Media encoder direct from the Vegas timeline.
I created a new preset project at 1920x1080 30P 32 bit mode. Then drag the .mov files onto the timeline. Render out as 1920x1080 30P .wmv two pass max sharpness 8MB/s stream and it seems pretty good for wmv.

I've tried to get it to .avi using the Cineform Neo HD which is capable of 1920x1080P .. but it doesn't seem to like the 30P H264 for some reason and crashes out .. or else gives audio but no video.

I reckon Cineform'll probably do something soon .. they're very good people.

BTW if you want tryout files my website has a load of zipped .mov untouched from the camera. These were my own 'evaluation' shots .. so don't expect 'art' ;-)

On the one test clip I've been using, the audio track was shorter by about 1/2 second (0:26:16 vs 0:27:02). That could be problematic on larger projects but not such a big deal if you're using off-camera audio (except maybe in the case you're trying to synch the offcamera audio with the standard track)

I hate to dig up old discussions as much as anyone, but it's only fair to note that, inspired by this very thread, the audio truncation issue has been addressed in AVFS 1.0.0.5: http://www.turtlewar.org/avfs/

I haven't been keeping up with 5D discussions since my participation in this thread, so I imagine most of you have moved on to other editing solutions by now, but if you ever have a project that will benefit from AviSynth frameserving and the AVFS plugin, you can now safely disable interleaving without knocking your audio out of whack.

Is there a way to import 5D footage into Adobe Premier CS3 and then use Media Encoder to get it into a better format? I am thinking about getting the 5D but I don't really want to spend money for software to make it all work if I do not have to. Advice would be appreciated.
