Optimize script commands FFMPEG with Limit CPU usage

I am working on a audio/video uploading and streaming project.

Process:

I have 2 audio files and a video file which I am processing with FFMPEG. I need to process these audio and video files in the below mentioned way:

  1. Generating thumbnail from the video file.

  2. Merging audio files with each other.

  3. then, merging the mixed audio file with the video file.

  4. after that, adding watermark over the video file.

  5. at last, splits video file into small chunks for streaming

ISSUE:

Everything is working fine but the issue is that all this process consuming very high CPU and TIME to complete. Is there anyway to optimize the FFMPEG commands to run in fastly. Right now, it is very slow!!

CODE:

I have created a bat file to complete the above mentioned process. Below is the source of the batch file which is executing over nodejs server.
