Solved VMS 17 Build 204 - Lost Audio Track
I used Derek's missing audio check list to try all the options where I may have inadvertently changed something, nothing found. I then created two new test projects. One using VMS 16 build 175 and the other using VMS 17 build 204, see screen shots. I have added two more screen shots to show that other .mts audio on the same track in my main project has a waveform and another to show the clip properties as seen in each of the test projects.
Why has VMS 17 build 204 given a different interpretation of the same clip as used in VMS 16 build 175 or VMS 17 build 179 where it was working fine before the build update? Any suggestions or help would be much appreciated.
Thank you @vkmast for providing links to an explanation for this problem.
Summary for any future readers
Vegas Movie Studio Platinum 17 and Vegas Pro 18, no longer support the import of MPEG-2 video that uses AC-3 audio.
When you import this older video format, only the video component will show on the Vegas timeline.
This change only effects the following build versions:
Vegas Movie Studio Platinum 17 build #204 and newer.
All older build versions of Vegas Movie Studio Platinum 17 can still import MPEG-2 with AC-3 audio.
Vegas Pro 18 build #373 and newer.
All older build versions of Vegas Pro 18 can still import MPEG-2 with AC-3 audio.
1. Use older program versions of Vegas Pro or Vegas Movie Studio Platinum, when working with older MPEG-2 video with AC-3 audio.
I would guess that many users of Vegas will have older versions they can re-install, when working with MPEG-2 video.
This would be the solution I would personally use.
2. Transcode all MPEG-2 videos using a Video Conversion program, before importing into your project.
I would recommend Handbrake as the best choice for this task
3. If you are using Vegas Pro 18, you can install Happy Otter scripts to re-wrap video into an MP4 container.
Happy Otter scripts is a paid product, but they do offer a 30 day free trial.
