no audio track on Timeline with 24bit?

jason-duncan wrote on 1/25/2018, 9:04 PM

I have Vegas Pro 12 and when I drop an .avi file that has an
audio quantization of 24b/48k into my Timeline, the audio track doesn’t appear.
Yet when playing the raw .avi file in Windows Media I can
hear the audio.

When I render a 16/48 file using WAVE PCM template 24/48,
and then re-import that into the Timeline, that audio track is there.

It seems only the audio captured with the Blackmagic
Intensity Shuttle usb3.0 will not appear.

Both 24b audio tracks are @2304kbps.

Anyone have suggestions? Thank you in advance~Jason

Can you share a sample file (e.g. on Dropbox, Google Drive, OneDrive, mega.nz, wetransfer.com or mediafire.com) for us to try?

I think without a download link from Dropbox we won't be able to access this file.

The audio doesn't open for me in VP12 build 270 and VP15 build261.

This looks like the same issue as in this thread. The audio is the same format. https://www.vegascreativesoftware.info/us/forum/avi-files-not-including-audio--109922/

Please leave the sample online so I can alert the developers to it.

This is the info from VLC. Looks rather odd.

david-tu: that's weird how VLC shows 32bit? The Shuttle captures audio @ 24b/48k.

Nick Hope: thanks for finding that other thread. Glad to see someone else has or had the same issue. I can just re-render the audio in another program down to 16/48. I was just wondering if there is better solution.

I don't think so at the moment. I suggest you get an FFmpeg Windows batch file set up so that you can either double-click it to convert all files in a folder, or maybe drag a folder onto it. It's really fast. There's some help (on a different type of format conversion) in this post: https://www.vegascreativesoftware.info/us/forum/faq-how-to-convert-mov-video-e-g-iphone-to-mp4-for-vegas-pro--106154/ If you search the forum for "ffmpeg batch" you'll find a few other examples kicking around. Can help you with the exact content tomorrow if you can't work it out.

Ok thanks Nick for that link. I'll try to mess around with that.

Quicktime Pro also did not recognize the audio file. Interesting.
