concat video woes #36

Open ern2150 opened 5 months ago

ern2150 commented 5 months ago

using mkvtoolnix:

concatenating two videos with the same codecs, but different resolutions and frame rates (same audio rate).

Error: The width of the two tracks is different: 1024 and 480

Used header editor to declare width and height of smaller video to match larger video.

Warning: The codec's private data does not match (lengths: 46 and 39).
