Using Vegas Movie Studio 9.
My son wants to use this program to edit some gaming videos he's created using the Elgato Game Capture HD device. The files are .mp4, and they play just fine in Windows Media Player. But when he tries to bring them into the timeline in VMS, he just gets the audio and no picture. When we right click on the files in VMS and look under Properties, under the Streams heading, we just see the audio.
Any thoughts?
