Video encoding

Since Visionaire Studio 3.7 we support matroska (mkv) videos with subtitles, this is while i want to give you some tips and inspirations to use that.

We recommed google's free VP8 video codec with ogg/vorbis audio for the mkv container. These codec has an very good quality which is similar to H.264, but there are no license fees.

Tools you need

• an video encoder / we recommed ffmpeg for it, because it has can read very much format's and convert it with an excellent quality.
• an subtitle editor for the format: Advanced Substation Alpha (ASS) / encoded File Encoding = UTF8
• an mkv editor like MKVToolNix
