I meant for upload in the video section... but if anyhow it's possible I will do it. I think MasterK77 and you both have given me to try uploading in downloads. I will do that. That's a very good option.
Here's what I did:
I made audio and then added background of the video and uploaded as a video file.
DId you create an Audio file of Commentary or background score?
I have created 'silent videos' demonstrating hands on activity and would like to add a background score to keep the audience engaged (silence may kill). Thoughts?
