In OBS's settings, I set hotkeys to switch scenes: I use F1 and F2 to select the Browser and Editor scenes, and F6 for starting and stopping recordings.

On a 4K screen, each quadrant is exactly full HD. The screenshot shows the Editor scene, which has a filter applied to its source to record only the bottom right quadrant. The top right and bottom right are my two recording scenes, usually a terminal or browser in the top right, and a text editor in the bottom right. The bottom left is a text editor with my speaker notes. The top left is OBS, for monitoring my recording and mic levels. To this end, I divide my screen into four quadrants. OBS can do much more than record screencasts, but I only use it for two things: Recording a portion of my screen, and switching between different portions.

Working on Linux, I used the Open Broadcaster Software, or OBS for short, as my recording program. Through some strange coincidences, wrote an article about my use of OBS. You can see the results of my efforts in my Qt for Python video tutorials and my file parsing with Python video tutorials. This is a writeup of what I did, in case I have to do more of it. Instead of holding my "Applied Programming" lecture as I normally would, live-coding in front of the students and narrating my foibles, this time it all had to be done online, thanks to the ongoing pandemic. However, this is beyond the scope of this quick tip.This semester is weird. The above may be an oversimplified explanation of remux vs encode. This simply changes the container which delivers the video without making any actual changes to the video content itself.Įncoding - This is the converting of the actual video and audio from one format specification to another. Remux - Copy the file from one container to another (MKV to MP4) without re-encoding. Unless or until the MKV format is more widely used, this is a blessing. Since you are no encoding anything it is often instantaneous. for i in *.mkv doįFmpeg makes it easy to remux video files from MKV to MP4.

The code below will loop through all the files in the current directory and convert MKV to MP4 files. If you use something like OBS Studio to create a bunch of videos and want to convert them all, simply use a loop. Videos]$ ffmpeg -i intro.mkv -codec copy intro.mp4 Convert All Files in a Directory from MKV to MP4 Here is an example using a intro we made for our YouTube videos. Then used the -codec copy option to instruct ffmpeg to use the same codec, followed the the name of the output file. Invoke ffmpeg then use the -i option to specify the input file. However, there are very few options needed to change containers. Using ffmpeg to Remux MKV to MP4įFmpeg is a very powerful suite of video tools.

In this Linux quick tip we will show you how to convert MKV to MP4 container.īefore you can convert (or remux) an MKV file to an MP4 file, you must first install ffmpeg. However, a lot of other tools (Adobe Premiere Pro) do not support MKV files. I have found that a lot of Linux utilities use the MKV (Matroska multimedia container) as a default container for video.
