Re: running a QT ref through Compressor Mpeg 2 creates a white export

If the QTref file is playing fine, then there is something wrong in the Compressor setting. I'm not familiar with Compressor. You can try downloading MPEGstreamclip. We also use the now discontinued VisualHub.

I used the same frame rate/format as the others that imported fine.

Yes. I had to export it to QT using MPEG Streamclip but I also had to buy the $20 plug-in.

Any ideas about that error? could it be a timecode glitch/skip?

It's an MC 3.1.1

Encoding High Quality Video: For YouTube

This is a guide for getting high quality material from your Avid timeline, into MPEG Streamclip and then finally on to YouTube so that you can make use of their "Watch In High Quality" feature.

Take the time to pause the guide and read each of the slides/stills prior to the video section as they do contain relevant information.

Addendum/Update (27-11-08):

Widescreen YouTube?

YouTube have recently introduced a 16:9 video player on their pages. This has brought a couple of pros and cons.

The main advantage is that native 16:9 material (640x360 / 854x480 etc...) now looks much better without letterboxing. Also, 16:9 material in 720p can now be uploaded and accessed as stated below.

The big disadvantage is that the "Watch in High Quality" link which worked brilliantly in the old 4:3 player, doesn't look all that great in the new 640x360 frame.

Videos uploaded in appropriate 640x360, 854x480, or 1024x576 sizes are compressed by YouTube down to 480x270 (which was fine in their old 480x360 player) and then resized during playback to fit the new 16:9 640x360 frame. This resizing process now blurs all encodes.

The only exception to this rule is if you upload 720p material 1280x720 with a good bitrate of around 5000Kb/s. If you upload this sort of file, you'll be able to access SUPER-CRISP 720p material by appending the video's URL link with &fmt=22.

Addendum/Update (25-11-08):

H264 vs MPEG4 Compressors & 720P HD?

You can safely use EITHER the Apple MPEG4 or H264 compressors to ensure the best possible visual quality you can manage (Adding now that you need to DE-SELECT B-Frames if using H264 compression).

It appears, as of 25-11-08 that YouTube now use a default 16:9 video player. This new player is a 640x360 size, so make sure any 16:9 material meets this resolution. 4:3 material retains its ratio but will pillarbox (and in some cases, letter box slightly below).

For adventurous types, you can upload 720p HD material and YouTube will recompress a 720p version (though not make it visually available by default as yet - you have to paste &fmt=22 into the video's URL).

Should you wish to "future proof" any HD material on YouTube, use these settings:

Compressor: H264 - Select Multipass & De-select B-Frames
Frame Size: 1280x720 (Better downscaling ON if sourcing from 1080i or 1080p footage)
Bitrate: Between 4000 & 6000Kb/s should work. (I've yet to confirm anything other than 5000Kb/s which I have tested.)

Uploading 720p suitable material direct to YouTube will ensure that any and all versions they currently create, will successfully be made, whilst preserving material for any future YouTube 720p default playback.

If the community video embedding feature is not working, you won't see the tutorial here. You will instead have to visit the dedicated Videos section to view it.
