Hello. How can I change the output settings of sound when using custom, when the input source is MPEG 1 Muxed? The custom dialog says "no sound".

Thanks,
Henry

Henry:

Podner's current implementation of Custom Encoding and MPEG muxed audio are not a combination supported by QuickTime's standard export dialog. When you select Custom Encoding, the muxed audio hasn't been extracted and resynchronized with the video yet, so the dialog has no way of knowing that it should allow access to the audio settings. If Podner were to preprocess the audio before the user selects Custom the user would experience a significant delay in the interface, especially if Podner assumes the worst case and preprocesses the audio for all files as they are dropped on its window. We might compromise by inserting a temporary blank audio track as the Custom Encoding option is selected, then remove that track as the export dialog is dismissed. That might be the best way all around - no overall performance loss, the ability to adjust the audio output settings, and a more accurate gauge of final output size.

I realise how and why you're doing the audio stripping from muxed MPEG1 files, but I guess what I'm asking is when the audio is extracted, and then finally resync'ed with the exported video, what settings are actually used? And how do I change them?

Could there not be a fall back setting? So, when the clip is preprocessed and the audio is extracted, it is recompressed with a setting that I can know about and change. At the moment the setting doesn't seem to be specified anywhere, but it must be something specified internally.

I realise that this could possibly be a little out of the scope of Podner, but it might be worth supporting, given you've gone to the effort of working around Quicktime's limitations with MUXed streams. In addition to moving clips to my iPod with video, I'm using Podner to process clips to stream from Quicktime Streaming Server in a better, and more efficient environment than using Quicktime Pro itself.

Once last thing, what I'd really like to be able to do is have the UI non-modal, so once Podner is processing, I can still add/remove clips from the queue.
