I've > tried it with totem, mvp and vlc. Any clue about it? I have not seen this effect on the playback speed. I am using the first video for testing. I do: $ make clean VIDEO=01-installation-from-script then, $ ./build-video.sh 01-installation-from-script This plays at the right speed for me in Videos/Totem (version 3.26). However, the concatenation question (for Firefox) may also be related to the speed question. Is super-speed very different from the expected speed? In the case of the first cli session for the first video there is a difference between the duration of the audio and video streams: duration1 (video stream): 1 minute 29 seconds duration2 (audio stream): 1 minute 18 seconds This difference may be treated in a different manner by different players. It may be necessary to add silence to the audio stream to equalize the durations and allow reliable concatenation without re- encoding. Best regards, Paul.
