VSO Free MKV-WebM Converter

VSO Free MKV-WebM Converter is a clear-cut software application with advanced options that you can use to re-encode video files to MKV or WebM format.

Extensive file type support

It's capable of loading movies from DVDs, Blu-ray discs or ISO images, in addition to common videos. The app offers support for a wide range of file types, including .avi, .3gp, .wmv, .mkv, .bdmv, .mov and .mp4.
It's wrapped in a clean and intuitive interface that you can quickly figure out. Batch processing is supported, which means that you convert multiple clips in bulk. Alternatively, you can merge videos into a single file.

Customize basic and advanced video settings

If a movie contains two or more audio tracks or subtitle streams, then you can select the preferred one to include in the new file. As far as advanced editing options are concerned, you can add a new audio track or subtitle stream, cut the clip into smaller parts, create chapters, or change the video bit rate. During this time, you can preview the movie in a built-in player to accurately make modifications.
Furthermore, it's possible to resize videos using filters for upscaling or downscaling, apply two-pass encoding mode and the best video quality settings available, adjust the audio compressor filter, force a specific subtitle language, burn the single file projects right after conversion or specify another post-task action, disable sound events, and so on.
