Replacing audio in Video

WaveLab
1

Im testing out the new Replace Audio in Video feature. I have added a MP4 H.264 video onto my video track.

But when I want to render out the, under the Output section the ‘Range of Active Video Clip’ is greyed out. And I don’t have the extra options under the Render options to replace the audio in the Video.

Is there a step I’m missing?

Ok, I solved my own problem. I dragged the video file onto the video track. But when I chose to import it in this corrected the issue. And now I can see the options.

In WaveLab 11.0.20 you won’t have this problem with drag n drop.
