Hi @ all
what is the fastest and easiest way to convert some .webm files to MP4
an Online Converter or a program ?
Thank you in advance

 

I like ffmpeg a lot but it's a commandline program.
It would look like:
ffmpeg -i video.webm video.mp4

Here's how to use it. I'd say it only makes sense if you have to do these conversions repeatedly.
