+1 for PPC support. We have a few machines we would like to use for batch capture only.

That would be 5 individual files, 1 video and 4 audio.

Thanks for the suggestions. Now, if I understand you correctly, in order to do a quicktime export as you describe I need to drag every captured clip to the timeline, which is what I am trying to avoid. I was hoping there would be a way to get FCP (or any other software?) to capture directly to 4 discrete mono files plus one video file in one pass.

Thanks Walter, that is an excellent answer. Unfortunately I utterly failed to communicate the problem properly. I am preparing media for a dvd project where I have 80 episodes of a TV show that each has 4 different language audio dubs (4 mono channels). What I want to do is capture the audio and video separately so that I can drop everything into my encoder. My issue is that fcp captures the audio files to one single file and to export each file from the timeline is quite time consuming given the rather large amount of media. A 3rd party application with batch capability would sure be nice so I don’t have to do it all manually using the timeline. Or is there a better way I haven’t thought of?

Obviously there is something wrong in your production flow because had you done everything right you would have had an image that filled your widescreen tv without looking stretched. If I were you I’d shoot some reference footage and run it through your normal production routines. Shoot something you know to be perfectly circular, and shoot it from the side in a straight angle. Center the object in your footage so that you can use it to judge if any sqeezing or stretching occurs later on in your process. If everything is correct you will see the same perfect circle in your footage on a widesreen screen without any bars.

I was a bit startled when reading the following from the “widescreen on video” link. I use a Canon XL2 and shoot 16:9 50i PAL footage and burn anamorphic DVDs. Does this mean I’m not getting widescreen? What does he/she mean by “standard formats use anamorphic techniques”?
It simply means that the only difference between 4:3 and 16:9 in the world of standard definition is how the frame is presented on screen. The formats are both stored in the 720×576(PAL) frame but will be stretched out differently when presented on your screen. There is no true widescreen frame format in that sense. A true widescreen format would be one where the information coming from the lens/ccd panels of your cam is stored in a 1:1 pixel aspect ratio frame. Ideally that would be 1024×576 in SD.
But to answer your first question: Yes you are getting as much widescreen as SD permits, though the correct technical term for “full” widescreen in SD is Anamorphic Widescreen. The term anamorphic has a long history in filmmaking and refers to the specific type of lens used to squeeze a wide picture onto a narrow chemical film. To get the wide picture stretched out again you just had to reverse the process in the playback projector.

I would adjust each clip in FCP prior to exporting to Compressor.

I haven’t found an article that explains it in detail but these I found somewhat informative.

The pixels don’t scale with the image. The number of pixels per area (or more accurate: vertical lines per frame) is constant in the wonderful world of video. Therefore when you downsize an image within a video frame you are effectively reducing the number of pixels (lines) that make up the image. Thus achieving less resolution.
The key is to understand the relationship between the frame and the footage.

The direct answer to your question is no, a timecode starting at 00 is not, to my knowledge, violating any part of the dvd specification per se. But to elaborate on that answer I’d like to add that the use of 00:00:00:00 causes major problems in other areas of production and is pretty much banned within the video industry. There are a number of good reasons to avoid using 00 as first frame. Mainly it boils down to the fact that tapedecks and other equipment (encoders, decoders, image restoration hardware etc.) need pre-roll time to operate properly. If a program starts at 00:00:00:00 there can be no pre-roll. So that is why professionally mastered tapes never ever start at 00.
That said, what is to stop you from altering the TC to suit your specific needs? Well technically nothing as long as you stay clear of professional video equipment, apparently including CCE. However, note that it is rather good practice to keep the original TC from the mastertape throughout the dvd production, and most professionally mastered tapes would start at 01, 02 or 10 hours.
