Hi, I had a play with one of my ffmpeg video conversion scripts. For the most compatible MP4 to deliver to your website visitors, I would use the 'main' profile with ffmpeg. As an extra, I looked at restricting the 'bitrate' and also using the 'veryslow' preset to try for better compression. The bash script attached I think gives wide compatibility and good end file size - around 10.6MB. I hope this is of help to you in its current form of if you wished to make changes to it for your needs.
