How to convert a MKV video to a less CPU intensive video format?

Question

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.

我应该将它转换成哪种格式以及我应该使用哪种 Windows 软件（如果免费更好）？

先感谢您。

MKV 只是容器，所以这不是问题。这是编解码器或图片大小的问题。处理大图像比小图像需要更多的能力。所以我认为这里的问题是图像大小。也许您应该尝试将其重新采样为 720p 甚至 576p。
