Audio Cutting Out - Returns after playback in Premiere Pro

howlyeye wrote on 9/3/2018, 6:01 PM

Hi everyone,

Lately I've been having issues playing back recordings done in NVidia's Shadowplay software while using Vegas Pro 15. The audio peaks build oddly in Vegas Pro, and at times, cut out - even when there are peaks visible. I tried putting the same clip into Premiere Pro and the audio plays back much better. After this, I realized today that the audio at the same point in time that was played back in Premiere Pro, now plays back in Vegas.

Hopefully this link is okay - it's a demonstration of the issue that I'm having. I'm on a fresh install of windows, all of my drivers are up to date, Windows is on the latest version.

My PC specs are:

i7 6800k

32GB Ram

The video was recorded to and accessed from an SSD.

GTX 1080 Ti

I really enjoy the Vegas Pro platform but I might have to switch to Premiere as my primary if these issues persist.

Thank you for reading this.

Just wanted to let everyone who is reading this know that I believe I found a solution. You have to access the internal preferences with Shift + Click on the Preferences, Internal, then look for an option called So4. I had to change "Enable So4 Compound Reader for AVC/M2TS" from TRUE to FALSE and this seemed to remake all of the peaks and play audio back correctly.

There is a way you can edit a dll file to only exclude that particular problematic format (a way to do this within Vegas preferences would be awesome, Magix), @NickHope might be able to help there. That way you are not breaking compatibility with some video formats, like GH5 10 bit camera footage.

To stop Shadowplay getting decoded by so4compoundplug.dll, without disabling it completely (which would break support for some other formats, as fr0sty says), change the contents of so4_blacklist_vp15.xml to this:

<?xml version="1.0" encoding="utf-8"?>
<filter_expr type="OR" comment="exclude IDR/I files where M = 1">
    <video Title="DJI.AVC" />
    <video Title="GoPro AVC" />
    <video Title="XiaoYi AVC " />
    <!-- Formats below added by user -->
    <video Title="VideoHandle" />
</filter_expr>

so4_blacklist_vp15.xml must be in C:\Program Files\VEGAS\VEGAS Pro 15.0\, which it will be if you are using VP15 build 384 or 387. For more info, see this post: https://www.vegascreativesoftware.info/us/forum/blacklist-for-so4-includes-fix-for-gopro-dji-xiaomi-yi-avc-lag--111716/

(I have no idea why Shadowplay files have the title "VideoHandle", or if other formats also use that title).

Thank you frosty and Nick. I added the VideoHandle to the exclusion list and that seemed to solve my problem!

 

Take care!
