How to use other file formats in VirtualDub

"Virtualdub unsupported file type"

VirtualDub2 now supports most formats.¹

VirtualDub on its own sadly doesn't support many popular codecs and formats, but there is a way to open your favorite mp4 or mkv (and many many others). The only thing you need is a plugin called Virtualdub FFMpeg Input Plugin².

Simply download the plugin³, copy the contents of the zipfile in your main folder of VirtualDub and (re)launch VirtualDub and you'll be good to go!

Supported formats by FFMpeg (a lot!)
