How to merge list of videos with frame specifiec order using ffmpeg ?
9 décembre 2015, par Il'ya ZheninI have a list of files :
even_0.avi
odd_0.avi
even_1.avi
odd_1.avi
...
even_n.avi
odd_n.aviAnd I want to merge them in a single video file in such a way, that zero frame would be taken from
even_0.avi
, first frame fromodd_0.avi
, second - fromeven_0.avi
and so on.And if all frames in
even_0.avi
are taken, then next frame we will take fromeven_1.avi
, next fromodd_0.avi
, next again from even_1.avi. Basically, when one video ends, we just start taking frames from the next video with prefix "even_
" or "odd_
".I just started using ffmpeg, know, how to simply merge videos, change resolution, fps and so on, but this is beyond my power, so, please, help.

Generate and concatenate videos from images with ffmpeg in single command
17 août 2022, par YulkyTulkyMy goal is to generate a video from images. Let's say I have 2 images
1.png
and2.png
.

I can do


ffmpeg -loop 1 1.png -t 3 1.mp4



ffmpeg -loop 1 2.png -t 5 2.mp4



to create a 3 second video from the first image and 5 second video from the second image.


Then, I merge the two videos using


ffmpeg -i 1.mp4 -I 2.mp4 -filter_complex "concat" final.mp4 



to create my final 8 second video.


This process seems extremely inefficient, and I feel I do not have to use all this processing power+disk reading/writing to create 2 intermediary video files when I only want the one final video.


Is there a way to execute this entire process in one ffmpeg command (efficiently) ?

Start of video is not labeled as "0" in QuickTime Video from GoPro
26 mars 2020, par John TerragnoliI’m trying to combine four GoPro videos into a single video, and then rotate it 90 degrees. However, the time scales on the bottom of the videos are all wrong. The videos are 17 minutes and 42 second. But the beginning time is labeled as 5:15:20:32 and the ending time is 5:33:01:32. It just looks really weird and I’d like to fix it. After I use ffmpeg to rotate and concatenate the videos, the problem persists. Could it possibly be fixed with Exiftool ?
ffmpeg -safe 0 -f concat -i list.txt -vcodec copy -acodec copy merged_videos.MP4
ffmpeg -i input.mov -vf "transpose=1" output.mov
Here is the exiftool information on one of the videos :

There is a pretty obvious "stutter" at the 17:42 mark where the two clips are combined. I’ve tried using ffmpeg and iMovie, but both give the same results. The GoPro broke up the event into multiple clips on it’s own so it seems weird that there would be any information missing. Is there any way to get rid of this stutter ?Thanks !
