Been trying and trying for hours but I can’t get any audio while using the Sony AVC option when rendering my videos. I have changed the “format” to .mp4 and then ticked the “Include Audio” option and set the options to: ACC (only options), 44,100Hz, 128,000bps, Stereo. I’ve also made sure the audio track is not muted either.
As a comparison, the MainConcept AVC/AAC encoder works flawlessly. Get audio and video just as expected.
Here are the MediaInfo logs comparing the two.

Tagged date : UTC 2011-11-14 07:09:05As you can see, there is just no audio track being included with the Sony AVC file. I have tried all different sample/bit rate options but I get exactly the same results, no audio track.
I have Googled my brains out and have yet to find a similar case to this.
The “easy option” would be just to render to MainConcept but bit rate to bit rate, the Sony AVC delivers a better (more detailed) pictured. This is especially true when it comes to gradients. Sony is much smoother. I really want to get this working.

Have you tried just rendering the audio separately? Eg, “mute” all the video tracks?
IF so what happens?
If success, unmute the video tracks one by one and see if there’s any in particular causing the issue…

If I mute all the video tracks, I do not get an option to render to Sony AVC.
I have tried multiple video clips, all from different sources. I’ve used, videos from: Fraps, Samsung Galaxy S 1 & 2, iPhone 4 & 4S and my old Sony DVI tape video camera.
All have no audio even when choosing .mp4 and selecting “include audio”.
I am using SCP11 x64. Have tried uninstalling and reinstalling. No change. Seriously think it’s a bug in the Sony AVC. Apparently others can render and receive audio. Really annoys me I can’t.

Sorry… I wanted you to render it as an audio file such as mp3 to see if it could be rendered.
You should also try just creating a blank video track. All black. And leave that on with the audio track. See if you can render that black video with audio.

From what you’re asking, it seems to me that you think my source files are the culprit. Let me assure you, they are fine. I can render .mp3 and .ac3 with no problems at all. All the audio is there, just as it should be.
I have also tried the “empty video track” trick and all I get is a black video with no sound. The audio track is just not there.
As you can clearly see from my MediaInfo reports, Sony Vegas Pro is not creating any audio tracks, it’s not even trying to. It doesn’t spit out an error. It’s like I’m not even clicking the “include audio” option.
This has got to be a bug in Vegas. I have tried every single combination of settings, files and who know what else. It’s just not rendering ANY audio, ever.

Hmmm… I doubt it’s a bug in Vegas or everyone would be experiencing the issue of not having any audio while rendering to that format.
Have you tried reinstalling Vegas from scratch?

[Dave Lozinski] “Have you tried reinstalling Vegas from scratch?”
Yes, I’ve tried this twice: uninstall, restart Windows, install.
I have read on this forum a user was having the same issue but changing the audio from 48,000 Hz to 44,100 Hz solved his issue. This doesn’t work for me, nothing does.
I think it’s worth nothing that this Vegas install was done on a brand new Windows 7 install, so there’s no conflicting programs or messed up registry settings. The first render settings I tried were Sony AVC because I wanted to test the GPU rendering. Been having this bug from the very beginning.
Maybe not many people try to render in Sony AVC + audio using .mp4? MainConcept AVC + audio (ACC) works perfectly but does not look as good bit for bit. I guess most/all people are happy with MainConcept. Either that or I am experiencing a 1 in a million bug.

I’m experiencing exactly the same problem with Sony’s AVC encoder. I’ve switched to MP4 and enabled audio but it’s not in the stream. Seems to be a bug in Vegas. Mainconcept’s encoder works fine. It’s pretty frustrating because the Sony encoder is two times faster than the Mainconcept encoder.

/Bernd”Good to hear I’m not alone. I’m not too fussed about render times but the picture quality is much better using Sony AVC, especially at 1080p.
Is there a way to mux/join Sony AVC with a separate audio file such as mp3 or ac3 without having to re-render the whole file?

Could this be the same issue that I’m having with Sony Vegas Pro 11 (Build 425 – Win 7 64bit) and new 1080p files shot on the iPhone 4s? They seem to import OK into a fresh project … images are on the files in Project Media and drag to the timeline to the right length, and images even show up on the video track. But no video plays. Nor does audio … most of the time … although sometimes it will randomly play the audio.
