I have a couple of videos at 1920x800 that use the MKV format (4.7 GB). A friend of mine has an old PC that has some problems playing them; the CPU is working at nearly 100%.
Is it possible to convert these videos to a less CPU intensive video format? The final size is not a problem, it can also double or more.
Into which format should I convert it and which software for Windows should I use (better if free)?
Thank you in advance.
