simply using shell_exec isn't enough. You need to create a queueing system likely with multiple rendering machines. It's not just a quick fix nor is it something that could be handled within the scope of a post like this.

Hello,

Thanks all for the answers. I understand that there is no problem with mu code, but this process (convert) need much cpu power.

Thanks agan !

The problem is you are trying to do multiple conversions at the same time and that is overworking the CPU. The best thing to do would be to modify your code to allow jobs to be queued instead of running at the same time.
