Is there a way to manually add a video codec to Speededit that uses H264 so when an MP4 is rendered the video will display on a website's HTML5 player?

I have noticed that editing and rendering an MP4 using the default methods in Speededit that it won't display the video portion. I have to then process the MP4 through Wondershare Video converter to render to an H264 that will display correctly on an HTML5 video player on a web page.

Thanks for the help.
