Import, edit, and save MP4 video files

[BowenM]

Basically, I'm going to need to import MP4 video files, add a stamp to them throughout the entire video, and dump them back to disk. This process needs to be automated.

Brief google search suggests the only ... simple possibility to do this in LabVIEW might be the IMAQ package. At the moment, I'm not looking for a solution, I'm just exploring possibilities.

Anyone have an arrow in the right directoin to do this in LabVIEW?  Maybe even an ActiveX or .NET package floating around somewhere...

Avisynth will do this for you.  Are you trying to add a changing stamp such as a timestamp or something static like a watermark?

Sorry for the delay. I hadn't run across avisynth before - it looks quite useful. To answer your question, it will be static (company logo).

If anyone stumbles across this at a later date, I did find a solution:  calling VLC from command line and having it add / save new video.

You may want to add vlc://quit before the --sout.  It will close the player when done
