Put video format the forum will accept by upload button.

I first tried a MP4 format but I got a "MP4 format not acceptable red" warning. I then converted the MP4 to a MP3/ wav file and the form acted as if it accepted it, but it is not showing on my post so I suppose it did not accept the MP3 either. I cannot show you the problem by video if I cannot find out what format is acceptatble. The acceptable format should be specified by the attachment tab. Thanks for your assistance.

Please tell me how to convert files to the desired format? Which program is best for this?

Yes, please tell us which platform is best for this.
