MKVToolNix is a collection of tools for the Matroska media container format by Moritz Bunkus including mkvmerge. The free and open source Matroska libraries and tools are available for various platforms including Linux and BSD distributions, macOS and Microsoft Windows.
Video converters are computer programs that can change the storage format of digital video. They may recompress the video to another format in a process called transcoding, or may simply change the container format without changing the video format.
Converting image subtitles to text formats is possible using third-party tools [128] but relies on optical character recognition, which is not perfectly accurate and can at best extract basic formatting. Conversion of text to images is possible while preserving content and style.
Using optical character recognition, SubRip can extract from live video, video files and DVDs, then record the extracted subtitles and timings as a Subrip format text file. [12] It can optionally save the recognized subtitles as bitmaps for later subtraction (erasure) from the source video.
Chapters: numbers of chapters, list of chapters [7] MediaInfo 0.7.51 and newer retrieve codec information optionally from tags or by computation. Thus in the case of misleading tags erroneous codec information may be presented.
Matroska (styled Matroška) is a project to create a container format that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. [4] The Matroska Multimedia Container is similar in concept to other containers like AVI, MP4, or Advanced Systems Format (ASF), but is an open standard.
Several open-source models for automatic segmentation have been described. [12] [13] Video segmentation information is typically processed by means of large language models, or combined with video Optical character recognition information, detecting the largest text in a slide (typically the title), to be used as the chapter title.
Disk menu and chapters creation - an option for DVD and Blu-ray video. [17] Freeze frame - make a still shot from a video clip. Stabilization feature - reduce jittering or blurring caused by shaky motions of a camera. [18] Enhanced deinterlacing method - increase video quality for interlaced input file - spots and blurred areas are compensated.
