Exporting HD from Avid MC
I am editing a job on a 1080p/60i timeline, and I would like to know my export options.
On test I am running now, using a 2 minute sequence, I picked a QT Movie, with 16:9 1920 x 1080.
The first thing I am enduring now, is that it’s taking forever to output. After processing about 4 hours, I haven’t yet got to 40% of the total, that is accomplished less than a minute. Is that time about right?
Any other way to process things further? Where can I get some explanation on HD export routines?

You have not stated what you want to use the exported file for.
The answer would be very different if its for an approval video to be uploaded to an FTP site than it would be for broadcast mastering.

OK. First of all I’d like a very high resolution video file that I can play from a computer, so I can show it to my client. As such it should play with VLC or MPC.
Later I would need an output that I can put on some HD media, like HDcam or others. I am not too familiar with HD media options, so I welcome any suggestions you might have.
I messed up on my last night Avid export, as it exported the whole time line instead of what I had marked in/ou, probably taking about 12 hours to do so. The timeline was 1h 41 minutes long.
The resulting mov file does not play as it should, so I wonder what I can use to run it.

In my experience, the AVid renderers can be very slow, as you’ve experienced. My workflow alternative is to always export at a Quicktime Reference file, then import that QTref to a third party renderer. Depending on what the delivery format is, I use different 3rd party renderers including:
MPEG_Streamclip
Tmpgenc v4
After Effects
Sorenson Squeeze5
Procoder 3

First obstacle would be that Avid MC does not export as QT Ref if the shots are Long Gop, as mine are.
Second would be that, if I am not wrong, those renderers you mentioned are SD, and I need something that can convert to HD, as I mentioned above.

Carlos, I export quicktime h264 for client approval and viewing. I shoot in 720, so I export 1280×720. 2 minutes at H264 (depending on your computer) should take 10-15 minutes, it does on my mac pro. h264 makes a nice picture at fairly low data rates.
What codec is you footage in, HDV?

I am mixing footage (on some sequences) in a 1080p/60i timeline: HDV and DV upscaled to 1920×1080.
Even if the DV blow-up turned quite good, and it mixes remarkably well with HDV’s on some cases, it does not in others. So I’m seriously thinking of exporting it all to 1280×720.
I have to export it as a QT Movie (because of HDV’s long-gop), but I can fill 1280×720 when doing so. What I do not know is how to export it as H264.

When exporting out of MC, select Custom and you will have access to all the QT codecs as managed by Quicktime. If you have QuickTime Pro, you will have even more control. H.264 is part of that submenu section (options).

Indeed, long form GOP will need to be transcoded to DNxHD before you can use QTRef,but that’s just another render step. If you do anything but curring, i.e. FX or transitions, you’ll have to transcode anyway. And no, all the renderers I list will work in HD. I work exclusively in HD, myself.
