Max number of videos to process in parallel. Raw format is difficult to preview and debug, however, in which case you may want to change frameFormat to png. Note: the default is raw for performance reasons, as writing and reading raw binary pixel data is much faster than encoding and decoding png frames. argsĭefault: Īrray of output-only ffmpeg command line arguments for the final video.

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. (example of 9 videos concatenated together with unique transitions) Concats a list of videos together using ffmpeg with sexy OpenGL transitions.
