Video Processor

Purpose

Ask any content creator and they will tell you that creating videos is a time consuming process. For me, the most mundane and worse part of the process is waiting on the videos to render and waiting on the uploads to complete.

Some video editors, have a version of their software that can be ran on a server to render the video files created. By offloading the video rendering to another machine, you can edit more videos in less time.

Purpose of this script is to automate the video creation process. Videos that I post on my various content platforms have a predefined structure for each video type. Thus they are easy to automate. When additional content or on screen text needs to be displayed, the automation for that particular channel is modified accordingly.

My YouTube Channels

Additional FFMPEG Commands

Occasionally, there are some additional FFMPEG commands that I need to run to create the videos that I desire to have. Since the commands are rarely used, I chose to not add the functionality that uses these commands into the script, but instead note them here for future reference.

Timelapse Video Without Audio

ffmpeg -i FILE0710.MOV -filter:v "setpts=0.5*PTS" -an FILE0710.timelapse.MOV

Create Video without Audio

ffmpeg -i out165.mov -an -c:v copy uncut165.mp4

Scale Video Resolution

ffmpeg -i out165.mov -an -vf scale=1920:1080 scaled165.mov

Concat Video Timelapse Files

for file in *MP4
do
echo "file $file" >> input.txt
done

ffmpeg -f concat -i input.txt -c:v copy output.mp4

Create Video With Image Files

ffmpeg -framerate 1/3 -pattern_type glob -i '*.jpg' -c:v libx264 -r 30 -pix_fmt yuv420p output.mp4

Add Music To Video

fmpeg -i 20230401_110000.mp4 -i ../../../ytvideostructure/07music/mix03.mp3 -shortest -c:v copy -c:a copy -map 0:v:0 -map 1:a:0 output.mp4

Convert Variable Rate Video To Constant Rate Video

ffmpeg -i input.mp4 -vf "setpts=1.0*PTS" -r 30 -c:v libx264 -crf 18 -c:a aac -b:a 192k output.mp4

Normalize Audio

ffmpeg -y  -i input.mp4 -f lavfi -i anullsrc -vcodec copy -acodec aac -shortest output.mp3

Rotate Video Clip

ffmpeg -i in.mov -vf "transpose=1" out.mov

For the transpose parameter you can pass:

  • 0 = 90° counterclockwise and vertical flip (default)
  • 1 = 90° clockwise
  • 2 = 90° counterclockwise
  • 3 = 90° clockwise and vertical flip
