Avidemux

(has GUI for both GTK and QT). (see Video->Frame Rate in application menu)

You could also try Virtualdub

Sorry for that last comment it was the wrong link. Also take a look at this to see if it helps.

Could you describe how to do that exactly with Avidemux? – Jakob Jun 02 '12 at 20:10

Just use ffmpeg - GUI programs always get outdated almost instantly

ffmpeg -i [input video] -filter:v "setpts=[RATIO]*PTS" [output video]

Here you have to replace [RATIO] with the number you get by dividing the duration (in seconds) of the output video with the duration of the input video. So if your traffic video original file is named traffic.webm and you want to name your output traffic-timelapse.webm the command would be (note that 30/(60*60) = 0.0008333 ):

ffmpeg -i traffic.webm -filter:v "setpts=0.0008333*PTS" traffic-timelapse.webm

What does -filter:v does? I have avconv, and it's pretty similar, but I haven't found this option in the documentation. In the end, I have a video where the video goes faster, but not the sound, and the "total time" displayed by VLC is the same as the input. – Rodrigo Mar 12 '17 at 18:53

You could use slowmoVideo for the purpose. The description of the software from their site:

"slowmoVideo is an OpenSource program that creates slow-motion videos from your footage. But it does not simply make your videos play at 0.01× speed. You can smoothly slow down and speed up your footage, optionally with motion blur."

You can find the latest Ubuntu build of this application at:

@Jakob, Yes that's true. But as the application's description clearly says, it can also be used to speed up the footage. – saji89 Jun 02 '12 at 20:12
oh, sorry! Could you describe how to do that? – Jakob Jun 02 '12 at 20:15

@DracNoc I recommend editing this answer to provide more information, or at least a link, for information about how to install Kdenlive and how to use its video speed effect. – Eliah Kagan Oct 02 '12 at 11:39

Under Effects -> Motion -> Speed you can set a speedup: https://userbase.kde.org/Kdenlive/Manual/Effects/Motion/Speed – Tully Jan 03 '15 at 08:13
