Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

Using ffmpeg to increase framerate without changing duration [closed]
11 février 2024, par sarunwI want to increase the video frame rate with FFmpeg.


I found from this website, https://trac.ffmpeg.org/wiki/ChangingFrameRate, that I can use
-r
orfps filter
.

The doc said the output duration of the video would stay the same, but that is not the case in my test.


What I tried so far.


I got a video with a duration of 19 seconds at 1.45 fps (I took this number from the QuickTime app)


After using these commands, fps become 30, but the duration becomes 1 second.


ffmpeg -i <input /> -filter:v fps=fps=30 <output>
ffmpeg -i <input /> -filter:v fps=30 <output>
ffmpeg -y -r 30 -i <input /> <output>
</output></output></output>
