Trouble exporting PS video WITHOUT sound

[flowerchild31]

I clicked the little sound button on the bottom left to turn off audio but when I export it the audio is still there... am I supposed to do something else to make sure there is no audio on export?  Thank you in advance!!

I see controls in the Video Time Line Palette for controlling sound in Photoshop playback.  I do not see any audio control in render video  to not encode the audio into the video file.  I'm sure there are video converters that can strip or separate video and audio.
