Now this is annoying.Â* Is there an add-on or
other way that will allow me to see just the game
and not the graphics trash on the sides?


Many thanks,

I tried a couple players in their so-called "crop" mode,
and I just couldn't figure out the arguments for the
WxH+X+Y format. Sometimes I'd get a slice of video,
sometimes I would just get a noisy part of the screen
and not the picture.

So I gave up on doing it the easy way.

I converted the 2GB downloaded video to 600GB of BMP files.
200,000 of them :-)

C:\ffmpeg\bin\ffmpeg -i L:\bears.mp4 -f image2 -q:v 1 -c:v bmp a%06d.bmp

I used IrfanView to crop the 1280x720 frames to 640x360.
The Convert option, Advanced settings, has Crop in it.
That converts the BMP folder into 150GB worth of stuff.

Next, split off the sound (because I don't know FFMPEG
well enough to do the remaining steps in one shot). This takes
no time at all, since it's a stream extract and copy.

C:\ffmpeg\bin\ffmpeg -i bears.mp4 -map 0:1 -c:a copy sound.mp4

The final render takes the 150GB video images, plus 100MB of
sound, and combines them. The T:\OUT folder has the cropped
640x360 images, one per video frame.

C:\ffmpeg\bin\ffmpeg -i sound.mp4 -framerate 30 -s 640x360 -i
T:\out\a%06d.bmp -c:v h264 -preset slow -crf 22 bears_out.mp4

And that's roughly a 1GB file, ready to play.

It even looks good in VLC, if I magnify the screen
to 2x.

See how easy video is ?
