How can I make smooth zooming video from image sequence in FFMPEG ?
26 octobre 2020, par CALKingI need to make a video from an image sequence, actually a deepdream image sequence I have generated. And I've generated the images so that every image is a 1.05 x zoom on the last image, hoping to be able to make something like this : https://www.youtube.com/watch?v=dbQh1I_uvjo. But because of the demanding CPU deepdreaming requires, I didn't have the time and resources to generate images for a 30 fps video, but more like a 1 fps video. Which I actually managed to do, my code for that looks like this :


ffmpeg -r 1 -i %04d.jpg -c:v libx264 -r 10 output.mp4



Now to make the video smoother I want to smoothly zoom in 1.05 x on every image in the sequence for about a second or two before continuing to the next image, which should then be in position with the one before. I have no experiene at all with FFMPEG and can't find much help on the internet. Could anyone help me with this ?


Thanks !

ffmpeg glue 4 videos on split screen with preview
18 janvier 2023, par rst630I have 4 video files 480x1080 with audio - all different duration.


I need 1920x1080 video

when first video done 2nd column video must start and first video must show just last frame, other left 2 videos still show first frame and wait queue


for example lets say we have these durations :


1.mp4 - 1:00
2.mp4 - 1:35
3.mp4 - 1:20
4.mp4 - 1:05



Also I can prepare screenshots of each video for preview frames (first/last)


Cant even imagine how to do this job with ffmpeg or maybe exists any simplier way for shell ?
