Node.js versions 10.13.0 and up are supported. This package runs on Linux, macOS, and Windows. 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) I know it is a complicated topic.Concats a list of videos together using ffmpeg with sexy OpenGL transitions. I don't really expect to be handed a solution but if anyone could point me to resources where I can find out more about the encoding systems and DTS and audio channels and how ffmpeg deals with these that would be a big help. I have found various sources about the error on SO but none of them really helped and most of them aren't even answered. Where the bitrate is the only difference, The bitrate is 2kb/s for some files and 69kb/s for others. Is there a way I can analyse the streams in more detail? I checked them with ffprobe and all the files report The issue only occurs after trim however, and the error message (Non-monotonous DTS in output stream) is the same.
As far as I can tell all the clips are in stereo at 44100. The cause appears to be different though. I am trying to concatenate a series of videos together and I am getting the same behaviour as this previous thread.
