Hi there,

I've been experimenting with streaming to YouTube Live Events and receive a low-quality warning from YouTube. Here's their message:

"Please use a keyframe frequency of 2 seconds or less. Keyframes are not being sent often enough, this will cause buffering. Current keyframe frequency: 5.0 seconds. GOP sizes can be wrong if you have ingestion errors."

How do I adjust the keyframe frequency with vMix streaming?

Thanks,

Michael

Look for a file profile.xml under C:\Program Files (x86)\vMix2012\streaming

and edit the file

Code:
        <advanced>
            <profile>Main</profile>
            <level>3.1</level>
            <keyframe_frequency>5 Seconds</keyframe_frequency>
        </advanced>
