[FFmpeg-user] 4K Way to large to stream

[rbarnes at njdevils.net]

Hi Nicolas,

I did a 10 sec preview from the middle of the file.  It is very grainy.  Is
the -s 384x160 the output Frame Size?  I think that would be way too small
for a 4K video convert.
I will play with the below commands.

-Ron

Just add "-r 5 -s 384x160" before the output file name. It should produce a
much smaller video, and finish much faster too.

Of course, I urge you to check the result to see if it matches your
expectations. And to peruse the documentation to see what these option would
do before doing it.
