MP4 Flip

[dbrillha]

Brand new here. Sorry if this is a common question. I just need a tool that can take a folder of MP4 video clips (from my GoPro) that are upside-down, and batch convert them. Turns out they need to be flipped both vertically and horizontally. And retain the original properties and meta data like telemetry, GPS.

I'm hoping this powerful tool can do it. If not do you know of a tool that can. Windows Movie Maker can, but I need to manually perform that one by one for each video clip.

Thanks!!

Both re-encoding in a batch with a video filter inserted to actually rotate the image and batch-remuxing (preserving original compressed frames, a very fast, almost instant procedure, no quality loss) as MP4 with rotation metadata added is easily possible.

However, retaining telemetry, GPS and, in general, any metadata is not possible with Avidemux.
