Update: Our distributor is requesting a QT movie file. These are the specs:

Video:
ProRes 422 (HQ)

Audio:
Multi-channel AES3 LPCM (302m) – minimum 16bit, 48kHz:
Ch. 1 – Left , Ch. 2 – Right, Ch. 3 – Center, Ch. 4 – LFE, Ch. 5 – Left Surround, Ch. 6 – Right Surround, Ch. 7 – Left Total, Ch. 8 – Right Total

I think I’m on track now but I still have a couple work flow questions. I have 8 audio tracks on the timeline. Ch 7 and 8 is the stereo mix. I unlinked the stereo mix and hard panned Ch7 left and Ch 8 is hard panned right.

I’m still not sure about the down mix db….Do I need to down mix to -3db (in the Audio Output Tab) or leave it at 0db?

Any help would be greatly appreciated!

Hey, thanks for the feedback!

I’m going to proceed with the DVD option. The movie is 80 minutes and I already used Apple Compressor to encode the DVD with VBR.
5.5 Mbps Average bit rate and 7.2 Mbps Maximum bite rate seems to be the “safe bet” from what I read on these forums.

I’m actually leaving right now to test the DVD at the theater, so I won’t have time to make another DVD, although I wish I had time to make one CBR DVD and test that against the VBR.

I’m using an AIFF for audio, and not AC3. The projectionist said that he could use Dolby Logic to emulate surround sound with a Stereo file and not AC3.

That being said, does playing a DVD with AIFF pose a problem for playback with a DVD-R?

Cheers,
Dan

Jean,
I really appreciate all your feedback and information. And the links are great! A must read for any budding producer!

Thanks for the feedback Ty!

I will be receiving version 1 of the LTRT mix and I need to QC it tomorrow.
(The mixers are in France and sending it over the net!)
Without access to a theater with proper surround sound, I will probably need to QC by opening the LTRT file in Quicktime and listening with my headphones or desktop speakers, nothing fancy.

Would opening the LTRT in Quicktime produce a stereo version that at least includes the 4 channels mixed down into a stereo file?

Thanks again for answering my questions… as you can probably tell I’m new to the audio/post world.
Cheers,
Daniel

Hi Shane,

I’m still dealing with this issue with my Canon XH-A1! And I still have not solved the problem.

This is what DONALD BERUBE (Director of Photography) wrote in response to a similar question I posted: (Please let me know if this worked for you or not. Best, Dan)

Currently as of FCP v5, Real Time Analog Video Pass-Through over FireWire does not work for HDV as it does with Standard Definition DV… it has to do with the GOP (Group Of Pictures) and the significantly greater CPU processing power required to process the HDV stream. The only time you can send an HDV signal back through an HDV camcorder via FireWire is when you go to the “File” Menu and then select “Print To Video”. Final Cut Pro will then need a short amount of time to re-conform the media on the timeline (recreate the GOP) and then the timeline is ready to be “printed back to video” – essentially meaning the timeline is ready to be displayed without dropping frames over FireWire into the HDV camcorder, where you will then be able to record the HDV signal to tape and/or pull the signal off of the Analog video outputs of the camcorder as the “Print To Video” process occurs and display it on an Analog monitor (Composite, S-Video or Component).

NOTE: You must specify in the “Audio/Video Settings” within Final Cut Pro whether you are outputting 60i or 24Frame material when using a Canon HDV camcorder. You can do this by going to the “Final Cut Pro” Menu, then select “Audio/Video Settings”, then click on the “A/V Devices” tab, then make sure that the correct selection is chosen under “Video” under the “Different Outputs For Edit To Tape/ Print To Video”. Example: For 60i HDV, you would select “HDV (1440×1080) 60i”. This will only be available if a FireWire cable is properly connected between your Canon XH or XL camcorder and your Macintosh. If you have an older or slower Mac, uncheck the “Mirror On Desktop” feature (provided that you have a monitor connected to your camcorder).

Please let us know if you need any further clarification on this matter and do keep in touch.

Thanks Donald! That’s excellent information. Sorry for getting back to you so late — I’ve been “off line” for almost a week shooting 3 commercials on the XH-A1. Lovely camera!

Best,

Thank you for the advice Richard.

Been married 1 week today. : )

Do you have any advise regarding my technical questions?

Best,

Issue Resolved!
I just had to re-render all the clips on the timeline.
