Hi,
I would like to know a native way in pd to alterate the data of a videofile.
Reading an mp4 with [text] or [soundfiler] objects cannot export to a valid video file... I guess this is a header issue but not really sure how to import/export to a video format.

Thanks

you may check the new [file] object that can read and write binary files.

Oh yes! thanks for the hint @jyg I forgot that new object!
