Optimizing preprocessing of data
12 mai 2018, par WhatAMeshI have to preprocess 1-2,5 Terabytes of 1920x1080 videos (in .mp4 format) and try to find the fastest way to do so.
For every video I have to :
- Sample at 1 fps
- Crop two images out of every frame
- Save the two frames (output format needs to be uncompressed)
Im currently doing it the following way using ffmpeg :
def cropVideo(vidInPath, vidOutPath):
crop = 'ffmpeg -i ' + vidInPath + ' -filter_complex "[0:v]crop=400:200:0:484[face];[0:v]crop=300:50:1624:300[number]" -map [face] -map 0:a ' + vidOutPath + '/face/face.mp4 -map [number] -map 0:a ' + vidOutPath + '/number/number.mp4'
subprocess.call(crop)
return
def videoToImageSequence(vidInPath, vidOutPath):
conv = 'ffmpeg -i ' + vidInPath + ' -vf fps=1 ' + vidOutPath + 'video-frame%05d.png'
subprocess.call(conv)
return
cropVideo(dirPath + a + '.mp4', dirPath + a + '/')
videoToImageSequence(dirPath + a + '/face/face.mp4', dirPath + a + '/face/')
videoToImageSequence(dirPath + a + '/number/number.mp4', dirPath + a + '/number/')Is there a faster way to do this ?

Resize/cut video to a certain region
18 mars 2023, par user3I have a series of videos (like 7k videos) in which I have to make a cut. Basically they are videos of people talking, and I have to cut said video and keep only the part of the lips.


Does anyone know how to cut them ? I need to be able to automate it


I'm looking for a command line software, where you can enter the coordinates and generates the new cropped video.


Is it possible to do it maybe with ffmpeg ? I couldn't find a way yet


Thank you !!!


I have tried to do it using ffmpeg, but I couldn't find the way to introduce the region (by coordinates) which I want cut
