jonel:

In my step 1:

1. When my song is ready, in the full Menu Bar at the top, > Save As > Save as video

when you say the "> Save As > Save as video" is not available, are you using BIAB 2020 for Windows?

The "Save as video" is not found under the "File" menu bar.
It's a separate icon (a floppy disc with the word "As" in red) on the full menu bar in the "File" area, and is labeled "Save As", with a dropdown arrow.
Right at the bottom of that dropdown is the "Save as video" selection.

If I follow my steps exactly, I get a video that's in sync.
Can you please try the process again with the above revised step 1, and let us know if it works?

Thanks!
