We are use ffmpeg for convert video to a specific form. The server is reaching 100% CPU usage, so my site is going down. That means the ffmpeg process has a strong effect on my main server.

Are you running ffmpeg on the server itself, or does the server only holds the files?

If you show your actual ffmpeg command and the complete log from the command we may be able to make more suggestions.

That seems to be a small server with 4 GB RAM and a virtual dual-core CPU that is most likely using shared resources. Obviously, this machine is not going to be able to handle video encoding tasks and serve a website at the same time, unless you make compromises in terms of the time it takes for the video encoding to complete.
Under Linux, you can run nice to reduce the priority of a process.
For example, run:
nice ffmpeg -i <input> <output>
The "niceness" values range from -20 to 19, and the higher, the lower priority a process gets. Without further options, nice adds 10 to the value of the process, which is 0 by default.
That said, I'd encourage you to not run web servers and intensive processing tasks on the same machine unless you can compartmentalize them in such a way that high resource consumption doesn't kill your website.

Another option is to offload the encoding to hardware, such as nvenc, if it is supported by your server.
