thanks John, unfortunately I am kind of obliged to use this particualar AV Player (Adtec Signedje) which can only output stereo or 5.1 sound. So DVD Players are nor really an option for me…

Thanks a lot Rob for your generous response. My usage for the AC3 is not too far away from what you did for this museum. I wrote to DOLBY now and see if they get back to me about this.

Cheers

Hi Rob,

a late thank you for your reply. Based on your tip I tried to create a 5.1 AC3 in Apple Compressor and unfortunately it actually cuts the frequencies of the .1 channel so that I end up with a low freq LFE channel. I have the possibility to uncheck “enable low freq effects” which sounded promising, but then it just gets rid of my file I threw into the .1 Channel. So it really seems to be an unavoidable thing that if creating ac3 files the sixth channel’s high frequencies get cut…?
If I understand it right though, the AC3 only “does” this in order to save space. As you said the job could also be done easily by the receiver (cutting the frequencies). So I still wonder if this is just the way my software (apple compressor) deals with the sixth file or if AC3s generally can’t take 6 full freq audio files?

Best
Alex

Thanks for your tip Ty but I am kind of dependent on the Player I am using. And before I change the hardware system I would prefer to find out if there is any way to stuff 6 full-freq audio tracks in one 5.1 AC3. So far nobody told me that it’s absolutely impossible…

[Alec Pale]

Thanks for your feedback Jean-Christophe. I am working on a video art installation and have 6 full-freq tracks, and an AV-Player device which can only output stereo or 5.1 AC3. So the trick with the 6.1 output unfortunately won’t work.
I have a video track and 6 synchronized Audio tracks. Life would be so easy if there was an easy way to create an 5.1 AC3 with simply 6 full-freq audio tracks, but it seems really hard…

I found a solution: with the basic 3D filter (which flops my image automatically without setting anything up, which I don’t understand?) it does the job. Now I can export the footage and it stays how it should be:flipped.

[Alec Pale]

Thanks Tony, but unfortunately it won’t render the flipped image either this way. So it generally doesn’t wont to flip it. Neither with the flop filter nor the motion tab rotation.

The length of the whole edit is 28 minutes. The pitch of the audio didn’t change. A framerate mismatch is unlikely I would say, as I exported the audio as aiff directly from the edit. It is a direct export and reimport from and into the same sequence.
