COMPRESS & SPLIT: OPTIMIZE YOUR VIDEOS WITH AVIDEMUX
We’re going to use Avidemux for two tasks:
Making your videos smaller so they load fast.
Cutting the video into shorter chunks.
PICKING THE FILE FORMAT
Let's break this down into 3 parts:
THE PROPER AVIDEMUX SETTINGS
THE RIGHT VIDEO RESOLUTION
We want to compress and convert the video to make sure it is compatible with all devices!
To do that use the following settings:
Video output: Mpeg4 AVC (x264)
Audio output: AAC (lav)
Container format: MP4 Muxer
Uncheck: “Use advanced configuration”
Preset: “Very slow”
Encoding mode: “Constant rate factor”
The higher you go on the slider, the better your video quality and the larger the file.
A Constant Rate Factor of about 23 is a good compromise between quality and file size!
If the resolution is large (e.g. 4k) you should make it smaller. 720 by 1280 pixels is a good resolution for a full screen vertical video.
PART II: SPLITTING THE VIDEO
We recommend splitting your videos into pieces that are less than 10 seconds long.
First: Open your compressed video.
Keep in mind: No need to compress the video again. We just want to slice it into pieces.
Second: Select copy under video and audio output.
Last: Use the slider to choose where you want the video to start at and where to end it.
Set "start marker" and "end marker" and save the video.
