This module requires ffmpeg to be installed. This module and CLI make it easy to concat videos together using gl-transitions.

Its extremely simple spec makes it really easy to customize existing transitions or write your own as opposed to struggling with complex ffmpeg filter graphs. GL Transitions, on the other hand, is a great open source initiative spearheaded by Gaëtan Renaudeau that is aimed at using GLSL to establish a universal collection of transitions. FFmpeg filter graphs are extremely powerful, but for implementing transitions, they are just too complicated and error-prone. Here are some convoluted examples of a simple cross-fade between two videos. (note that the quality and fps is only poor due to the GIF preview here is the original)įFmpeg is the de facto standard in command-line video editing, but it is really difficult to concatenate videos together using non-trivial transitions.
