MPEG-4 Part 2 SP/ASP (using libavcodec)Īvidemux supports following file formats:.Earlier versions of Xvid are not compatible with this feature.MPEG-4 Part 2 SP/ASP (using libavcodec or Xvid).Multithreading has been implemented in the following areas of Avidemux (some partially through libavcodec): The primary (though not the only) Avidemux programmer uses the nickname 'Mean' on the Avidemux forum. The built-in libavcodec library from the FFmpeg project is used for decoding and encoding of various audio and video formats such as MPEG-4 ASP. Nonetheless, it is a completely standalone program that does not require any other programs to read, decode, or encode other than itself. Avidemux supports various subtitle formats, including MicroDVD (.SUB), SubStation Alpha (.SSA), Advanced SubStation Alpha (.ASS) and SubRip (.SRT).Īvidemux was written from scratch, but additional code from FFmpeg, MPlayer, Transcode and Avisynth has been used on occasion as well. A project queue system is also available.Īvidemux has built-in subtitle processing, both for optical character recognition of DVD subtitles and for rendering hard subtitles. It also supports a non-project system just like VirtualDub, where users can simply create all of their configurations and save the video directly without making a project file. Like VirtualDub's VCF scripting capabilities, Avidemux has advanced scripting available for it both in its GUI and command line modes. Whole projects with all options, configurations, selections, and preferences can be saved into a project file. Avidemux can also insert audio streams into a video file (an action known as multiplexing or "muxing") or extract audio streams from video files (an action known as "demuxing").Īn integral and important part of the design of the program is its project system, which uses the SpiderMonkey JavaScript engine. Some of the filters were ported from MPlayer and Avisynth. Features Īvidemux is capable of non-linear video editing, applying visual effects (called "Filters" by Avidemux) to video, and transcoding video into various formats. Unofficial builds are also available for FreeBSD, NetBSD, and OpenBSD. Starting with version 2.4, Avidemux also offers a command-line interface, and since version 2.6, the original GTK port has not been maintained and is now discontinued.Īvidemux is developed for Linux, macOS, and Windows. It is written in C++ and uses Qt for its graphical user interface, and FFmpeg for its multimedia functions. The developers intend it as "a simple tool for simple video processing tasks" and to allow users "to do elementary things in a very straightforward way".

I found a good tutorial on the internet with Adobe After Effects, but the Adobe software is too slow and certainly noone here would like to shift to a competitor!īelow the AfterEffects settings which most seem to give me the best output color correction. Used several video editors before, but relatively new to PowerDirector12. I also downloaded some filters on the internet, but the colors become so patchy that it's worthless. I would like to add a filter in post-production and I was surprised to find no agile settings in PD12. I shot hours of underwater videos whilst scuba diving this summer with my GoPro, unfortunately without a red filter.
