There is no reason I can think of at all to give a FCP editor an AC3 file. Just pass your editor the WAVs and be done.

[Adam Rickets] “I cannot find any setting in Compressor that will let me alter the resulting file’s timecode.”
My question would be: why? Why would you need to do this? I am curious, but I assume that AC3 files created this way don’t have a timecode track, and it’s just written by whatever application it goes to next.

Sometimes in order for this to work, you have to make a new bin, drag all of the AMA clips and all of the ‘ducked’ clips in. When they’re all in the bin, then you can select them all and relink based on current selection. Or relink based on AMA file name, or something like that. It takes a lot of playing around like this to get AMA clips to link to ‘ducked’ clips, but it does work.

[Anthony Vamvakitis] “The on-site playback person wants 59.94 sequences interlaced”
What they really mean is 29.97 frames per second, interlaced.
What you need to do is take your 23.98 cut and convert in Compressor, but this time *not* to 59.94 but to 29.97 with Top Field first. Bring the file into Compressor, drag your previous setting on, and change the frame rate to 29.97, making sure that in the video settings window you choose “Interlaced” and “Top Field First”. Then in Frame Controls, turn it ON and set everything to Fast, and set output fields to Top First.
This will give you a file with the correct 2:3 pulldown sequence to get you from 23.98p to 29.97i.

Since your source file doesn’t have any pulldown, doing a pulldown removal wouldn’t be a good idea. I would use Compressor and engage Frame Controls to set retiming to better. Best retiming will take forever and likely not give you any real gains in quality. Make sure Compressor knows your source file is progressive, and set it to encode to ProRes at 23.976 fps, better retiming, 100% of source. Be prepared for it to take a while, but I’ve had success with this method.

Open QTChange
Click “Select source folder” (folder where your QTs live)
Choose tracks to delete (A1, A2, etc.)
Click “Do it”
done.Please be aware there is NO undo to this process, so make duplicates of your source footage prior to this process if you think you might want to go back at some point.
-
Yes you can. A Cinema Tools “Conform” process only changes the speed at which the files will play back. Simply open in Cinema Tools again and click “Conform” and choose 29.97. Voila, you’re back.

You’d need an SR/2 deck with Ethernet adapter and software that understands the protocol – I believe Sony has a proprietary app that can ingest/output the HDCAM-SR codec MXF. I saw this on display last year before the /2 deck launch. Other apps that can understand and access this are Avid Media Composer and Sony Vegas.
Is it worth it? IMHO, No. The tapes are better storage units. If you really want to archive as files, go with Apple ProRes HQ or Avid DNxHD. You will make everyone down the line much happier.

Don’t know about automating it, but the combination of Perian and MPEG Streamclip always works for me. And you can batch convert in Streamclip, so this may be an option for you.

QT Change is what you’re looking for – demo version is free for 8 clips at a time…
