Similar project that attempts to use frei0r and MLT instead of extending ffmpeg directly.gl-transitions and original github issue.Excellent example ffmpeg filter for applying a GLSL shader to each frame of a video stream.This module and CLI are easier to use than the lower-level custom filter provided by this library. ffmpeg-concat - Concats a list of videos together using ffmpeg with sexy OpenGL transitions.transpile webgl glsl to opengl glsl via angle.add gl-transition logic for aspect ratios and resize mode.remove restriction that both inputs be the same size.this is the reason a lot of gl-transitions currently appear to not function properly.support default values for gl-transition uniforms.

simplify filter graph required to achieve multi-file concat in concat.sh.

See here for a more complex example including audio stream concatenation. See here for a more understandable example of concatenating two, 5-second videos together with a 1s fade inbetween. There is no limit to the number of video streams you can concat together in one filter graph, but beyond a couple of streams, you'll likely want to write a wrapper script as the required stream preprocessing gets unwieldly very fast. If you want to concat audio streams in the same pass, you'll need to additionally make use of the asplit, atrim + asetpts, and concat (with the a for audio option) filters. See concat.sh for a more complex example of concatenating three mp4s together with unique transitions between them.įor any non-trivial concatenation, you'll likely want to make a filter chain comprised of split, trim + setpts, and concat (with the v for video option) filters in addition to the gltransition filter itself. Note that both duration and offset are relative to the start of this filter invocation, not global time values. See here for a list of glsl source transitions or the gallery for a visual list of examples. This text file must be a valid gl-transition filter, exposing a transition function.

source (optional string defaults to a basic crossfade transition) path to the gl-transition source file.

Any frames outputted before this point will pass through the first video stream untouched.

offset (optional float default=0) length in seconds to wait before beginning the transition.

Any frames outputted after this point will pass through the second video stream untouched.

duration (optional float default=1) length in seconds for the transition to last.

ffmpeg -i media/0.mp4 -i media/1.mp4 -filter_complex "gltransition=duration=4:offset=1.5:source=crosswarp.glsl " -y out.mp4 The main advantage of using EGL is that it is easier to run in headless environments. On Linux and Windows, there are two options, either using EGL or not using EGL. Use spread and blend sliders to control the color correction harshness. Leverage highlight, shadow, and midtone masks to adjust color range. With a variety of controls and filters to choose from, you’ll be given total freedom in your video to achieve the perfect look.

Dependenciesįirst, you need to install a few dependencies. If you’re looking for the best color correction software for video, our ColorFast 2 is the perfect solution. Don't worry, though - it's surprisingly straightforward.

So we did some testing and have found these best video editing software for Mac to suit varied needs. Since this library exports a native ffmpeg filter, you are required to build ffmpeg from source. This can take your videos to the next level and make you stand out from the crowd. This library is an ffmpeg extension that makes it easy to use gl-transitions in ffmpeg filter graphs. 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. IntroįFmpeg is the defacto standard in command-line video editing, but it is really difficult to concatenate videos together using non-trivial transitions. If you want an easier solution, I recommend checking out ffmpeg-concat, an npm module and CLI that allows you to concat a list of videos together using a standard build of ffmpeg along with the same sexy OpenGL transitions.
