I'm trying to figure out a way to convert horizontal video to vertical without losing any quality. I thought this would be pretty straightforward but it turns out absolutely not.
Anyway, I'm wondering if there is a way to encode vertical video with RAW data? I was thinking that since it is not encoded it might be pretty straightforward to do this but if there's anything I learned today it's that I know absolutely nothing about how video is encoded.
turn the camera sideways (https://www.magiclantern.fm/forum/index.php?topic=19336.msg182890#msg182890) I did this with adtg_gui (https://bitbucket.org/hudson/magic-lantern/src/6387a02cde0ab84a83a7696906e3bf9101aa10ce/modules/adtg_gui/adtg_gui.c?at=iso-research&fileviewer=file-view-default) you need to compile the iso_reseach branch and I ended up with 3000x1250 .Or in post turn the image 90 degree or are you trying to do this in camera ?
you can do it in after effects, or similar program too.
