Extract final frame from a video using ffmpeg
14 mai 2020, par SaavestroI know how to extract the first frame by using



ffmpeg -ss 00:00:00 -i input.mp4 -vframes 1 -q:v 31 output.png


Here, the option
-ssrequires to know the exact time of the frame to extract.


I would like to have the final frame of any .mp4 without knowing the exact final time of the video.



Is there a way to achieve this ?

Is it possible to use FFmpeg to cut "random" sections from a folder of videos and concat them into 1 video ?
14 novembre 2018, par EmmyStrandI realize this sounds like an easy question, and one that has been answered before. However, I cannot seem to find a script which can read a folder of videos with varying lengths, copy a random segment from each video, and concat them into a single video.
An example :
I have a folder with 150 videos labeled Fashion-Setlist-01.mp4, Fashion-Setlist-02.mp4, etc.
Each are over 1 hour. I would like to pull a random 10 seconds section from each video and then randomly add them together resulting in a video. This may seem easy with only a few videos, but the plan is to read from potentially 100’s of videos. It should be possible to pull multiple sections from each video as well. I suppose we could run the script twice for more segments if the video needed to be longer. -
