How to render a group of videos into a larger video with FFmpeg
17 octobre 2020, par thewaymanHow do I render a group of videos in a grid where video size and placement is variable.
I know how to merge two videos with FFmpeg, but how to do it for a grid.


ffmpeg.exe -i "2.avi" -vf "[in] scale=640:480 , pad=width=640+640:height=480:x=0:y=0:color=red [left];movie=1.avi, scale=0:480 , pad=width=640:height=480:x=(640-480)/2:y=0:color=red [right]; [left][right] overlay=640:0 [out]" -b:v 768k "Output1.mp4"

ffmpeg split videos from times in csv file
10 juin 2018, par martinsI’m using Python 3.6. I am trying to split videos into subclips of specified time. I have a folder with 250 ".mp4" files and a separate csv with the times at which I want each video to be subclipped. For instance, a first .mp4 file would be "firstvideo.mp4" up to "twohundredfiftyvideo.mp4". Separately, I have a csv file with each video file name in column A and the timing at which each video needs to be split (column B to I). All videos need to be split into 4 subclips. The .csv looks like :
col A col B col C colD colE .. colI
row1 firstvideo.mp4 00:00:10 - 00:00:20 - 00:01:15 - 00:02:04 .. 00:07:15
row2 secondvideo.mp4 00:00:15 - 00:00:34 - 00:01:05 - 00:01:55 .. 00:08:23"firstvideo.mp4" needs a first split from second 10 to 20, a second split from 1m15s - 2m04s and so on (colI is the time at which the fourth subclip should stop). The process should iterate for each of the 250 rows of the csv file corresponding to the 250 mp4 files in a folder.
So far, the only thing I know is to use ffmpeg to split videos into 4 subclips and generate 4 different output files but do not know how to read from the csv line by line... This is the code I have so far.
ffmpeg -i firstvideo.mp4 -vcodec copy -acodec copy -ss 00:00:10 -t 00:00:20
firstvideo_1.mp4 -vcodec copy -acodec copy -ss 00:01:15 -t 00:02:04 firstvideo_2.mp4 -vcodec copy -acodec copy -ss 00:03:48 -t 00:04:23
firstvideo_3.mp4 -vcodec copy -acodec copy -ss 00:05:30 -t 00:07:15 firstvideo_4.mp4I name each output file with a _1,_2,_3 or _4 appended to the original video file name. Ideally, I would generate 4 subclips per video (i.e. 250 videos x 4subclip/video = 1,000 mp4 files) and then concatenate each video 4 subclips into one file (i.e. 250 additional files). In fact, I don’t care about the 4 subclips, I’d delete them after they generated my concatenated file.
Thanks for your time anyways,
