Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

Error creating folder based on file name in ffmpeg
18 janvier 2023, par user21008368I've been trying to convert multiple videos into image stacks using ffmpeg. I would like to convert multiple videos at once, and export all the images from one video into a new folder, named after the video.


I've found the following code from a previous question, but I can't get it to work on my computer (I'm using a mac).


@echo off for %%i in (*.mp4) do (if not exist "%%~ni\" MD "%%~ni" ffmpeg -i "%%i" -vf fps=1/1800 "%%~ni\%%~ni_%%d.jpeg")

I keep getting the error


parse error near%%i`

I think this is probably a syntax error, but I'm relatively new to using ffmpeg and working in the terminal.

I want to place a heart transition I made between 2 videos with 2 blank png images with alpha , with a 4 sec transition in mkv format with overlap
14 juillet 2022, par ChristopherI want to place a heart transition I made that has 2 blank png images with alpha channel, that has a 4 sec heart transition that is in mkv format. I want to overlap the last image of the 1st video, with the transition video for 2 seconds, and overlap the first image of the 2nd video for 2 seconds. This would allow a heart transition, between 2 baby animals, between the clips that make up the videos. I have conceived a way to automate the assembly of over 1800 clips into videos, and this is a part of it. Sorry about the absence of clarity in my question, I hope this makes it clear, what I am trying to accomplish.
