The second pass will extract the segment, now aided by key frames. In this example, generate 30 fps video from 30 fps images. The first pass will generate key frames all across the segment and store the result in a work-in-progress file.-pix_fmt : pixcel format to give encoder, in ordinary yuv420p.-r(option) : specify frame rate(this example, 30 fps)įrame to Video with ffmpeg ffmpeg -r 30 -i img_%04d.png -vcodec libx264 -pix_fmt yuv420p -r 30 output_video.mp4.Video to Frame with ffmpeg fmpeg -i video.mp4 -vcodec png -r 30 img_%04d.png zfill(n) : making 0 fill and 4 digits serial number.import os import cv2 def video_to_frames(video_file, image_dir, image_file="img_%s.png"): i = 0 cap = cv2.VideoCapture(video_file) while (cap.isOpend()): flag, frame = cap.read() if flag = False: break cv2.imwrite(image_dir + image_file % str(i).zfill(4), frame) cap.release() # execute video_2_frames("./video.mp4", "images") Reading a video frame by frame with OpenCV and save them as images. install ffmpeg for linux/ubuntu sudo apt install ffmpeg Video to Frame with OpenCV In addition this, I introduce the way to generate video from frames by ffmpeg. What is important is that you properly reinterpret them when you encode or playback those jpegs, telling ME or ffmpeg their proper fps, in your case, 27780/1000, and if they should. In this story, I write the way to split video frame by frame with two ways, using OpenCV or ffmpeg. A frame is a frame, if a video has 200 frames, you will generate 200 jpegs from it regardless of the fps, fps is just the rate that you are playing those frames. awesome-ffmpeg - A curated list of awesome ffmpeg resources with a focus on JavaScript.Spliting Frame and Generating Video with OpenCV or ffmpeg. ![]() fluent-ffmpeg - A fluent API to FFmpeg. ![]()
