How I speed up making videos (on YouTube and Instagram)
Yesterday I came across the exact solution to a problem I was facing.
Because I am doing Instagram stories right now about lessons that I have learned and want to share to other people. But the problem here is, that I am too lazy to edit out all the moments that I am pausing in the moments between speaking.
This right here is the most amazing project that I have been fortunate enough to learn about in the recent past:
What I can do with it is cut out pauses out of a talk video, like I’m doing on my Instagram.
So how can you use this program that is being displayed in the video?
There is a couple of requirements:
- First just go to the github page: https://github.com/carykh/jumpcutter
- Download or clone the files that are on there.
- (Optional on Windows, download Git bash: https://git-scm.com/downloads) With this you can right click on a folder and open a commandline window.
- Make sure you have python installed. (for windows, I used this guide to make sure I could install Python 3 smoothly: https://www.howtogeek.com/197947/how-to-install-python-on-windows/)
- Make sure that you have ffmpeg installed. For example on Windows: https://www.wikihow.com/Install-FFmpeg-on-Windows
- Then you are going to open a command window like this:
- Then in the above image you can see that we have to run the command
pip install -r requirements.txtin order to install all the necessary dependencies. - after that we can just run a command like:
python jumpcutter.py --input_file 1.mp4 --sounded_speed 1 --silent_speed 999999 --frame_margin 2
This command will cut away all the video that doesn’t have any audio. So when you are making a talk video you can cut away all the pauses and have an entertaining video! :)
Note: this method didn’t really work well for my YouTube tutorials where I am showing things while talking. The synchronisation went really bad. It would be really good if it worked, since the video duration was cut from 21 minutes to just 15 minutes.
