In general, with newer FFmpeg versions there is (almost) no reason to use the slow seeking anymore. ffmpeg -i 36017P. That code simply converts the MLT XML with no access to Shotcut or MLT APIs. I have no idea, as the client has been commissioning a lot of work from a lot of iPhone/Mac writers I know, but has a lengthy review/rewrite process. avconv is a very fast video and audio converter that can also grab from a live audio/video source. Then, an mp4 file for video is created, with a slow preset (how fast it converts), with the encoder tuned to a film source medium (use -tune animation for animation or -tune grain to preserve grain), with -vsync passthrough to prevent ffmpeg messing with the frames, without the timecode track that may be found in files exported from final cut, without audio, with a x264 codec with every 25th frame an I-Frame, with a constant quality rate of 22 but not more than 5000 kbps, using a buffer size. Transport Stream had been originally designed for broadcast. 4 ffmpeg: preserve timecode when converting mp4 to mov 2016-03-18T23:26:01.
