How to convert youtube videos to mp4 instead of webm?

[Battery]

Hi I was wondering how I can download videos as mp4 rather than webm and also how to download videos as mp3 files, since I purchased the license.

VDH downloads what is being streamed or is available to stream, everything available for VDH to collect and decrypt or simply download where there is no decryption is all you can obtain through the program,  if there's no stream that confirms with your desired type ... then you can't

I suggest you try experimenting with Download and Convert.

You can also just download whatever it is then use the Convert Local Files function after the fact.

How do you use those things?  Figure it out for yourself.  Experiment.  Be adventurous.  These things aren't that complicated.  Try it.  Don't be a fraidy cat.
