Bash Script to Process Videos w/FFmpeg to Video Contact Sheets and Move them

I currently have a set of scripts that does all that I'm asking for, however, it does it in steps.. I need it to do them one after another with one command, currently, I have to run four commands in a step process. Videos get downloaded -- Upon completion of the downloaded mp4 or flv the script will activate... and it will... ----- ffmpeg (-copy) function the video into another directory. ----- delete the old video file ----- once in the directory the script will create a thumbnail contact sheet of the video. ----- ------ I will review the contact sheets, deleting some of them.... ----- ------ I will run a command in ssh that will then do the following... ----- ------ ------ If the video still has a contact sheet it will then move that video to another directory. ----- ------ ------ If the video does not have a contact sheet it will then delete the video file. ----- ------ ------ Once video is in another directory it will RSYNC to another server. ----- ------ ------ Once RSYNC is completed it will delete all videos and video contact sheets it has created. Here is a copy of the bash scripts I have to that currently does this, but it's not a combined effort, it's me running a command in ssh process 1, once finished me running command 2, process 2 starts/completes and repeat... i want to make this as automated as possible. I will provide the three scripts I have that currently does this, I just need them combined so that once a video has downloaded a "post process" will occure to that completed video... Then I can log in, ssh one command and the rsync and delete process starts....
