Does anyone know how to convert a 10bit Uncompressed Mov with the Custom frame size of 1344 x 384 to an MPG2. Its to be broadcast on a large LED Screen in China at that resolution. They are insisting on that frame size and that it be an MPG2. I know that the MPG2 algorithm doesn't like custom sizes but How can you get a custom frame size?
Did you try ffmpeg with the scale video filter? ffmpeg -i input -codec:v mpeg2video -vf scale=1344:384 -qscale:v 2 output.mpg
Range for `-qscale:v` with this encoder is a linear range of 1-31. A lower value results in higher quality.
Note that this will force a size of 1344x384 which, depending on your input, may result in a stretched or squished look. You can use the crop or pad filters to compensate:
I tried ffmpeg. I just could not get it to work. Actually the uncompressed file is already cropped and resized so I was looking for a one to one conversation. Every time I tried to export under mpeg2 it would either resize the frame or error and quit the export.
Fortunately someone in another forum suggested using Adobe Media Encoder. I used that and was able to get it on the first export.
Thank you so much for your input and I will give your suggestion a try.
