I’m trying to upload some video from an archive. The video playback looks good, but the thumbnails are in the wrong dimensions.
They seem to be 4x3 while the video is 16x9. I added a thumbnail as example. The original is an older file encoded as MPEG-2 SD broadcast quality (.m2p)
These files use the PAL standard with a broadcast-stream picture size of 720x576 pixels. 16x9 was achieved with non-square pixels.
Video: mpeg2video (Main), yuv420p(tv, top first), 720x576 [SAR 64:45 DAR 16:9], 8000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc
I have about 2TB of these files and am not looking to re-encode the whole archive. That would be almost undoable for my MacBook or NAS and lead to a loss of quality in these already SD files. Two examples are
Any idea how to fix this? Thanks!
