Yes. Let me explain. First and foremost, with transcode, to render subtitles and to embed them in the video stream requires a decode/reencode cycle (and I'm not aware of any tool nor technique that allow to avoid that). So, _video_ passthrough don't work and will not work. Second issue: that passthrough in transcode is known broken, so isn't reliable (yes, we acknowledge that is a serious issue and we'll solve this a soon as is possible). Third and last (few!): transcode still lacks MPEG muxer, so it cannot produce a full-featured vob. Anyway, is it possible to produce the elementary streams (separate audio and video track) and multiplex them with mplex (from mjpegtools). This limitation will be wiped away as well in future release (exact timing depend on amount of our free time, help welcome :) ) have tried other encapsulations with no help (-y options) ... the > original vob size is 6GB and resulting vob is 36GB before i stopped > transcode ... try something like -y ffmpeg -F mpeg2video -N 0x50 This will produce audio and video track in vob-compliant format. Also remember to reduce bitrate using -w. HTH Bests, -- Francesco Romani // Ikitt
