You will need to download FFmpeg for this tutorial to extract images from a video. It contains multiple tools for end-users to convert, play and analyze media files and libraries for developers to use in different applications.

It is also highly portable as it compiles and runs in a wide variety of build environments, machine architectures, and configurations like Linux, Mac OS X, Microsoft Windows, etc. It can decode, encode, transcode, mux, demux, stream, filter and play pretty much any media file in any format.

In this tutorial, we will be using the FFmpeg command-line tool to extract images from the video below using several different commands. You can use it to generate thumbnails for your videos or take a screenshot of the video at any given time. Hopefully the names of the resulting MP4s are the same as the original split segments, which makes the next step more convenient.Ĭopy the list.ffcat created in the initial segmenting command to the results folder and run ffmpeg -f concat -safe 0 -i list.ffcat -c copy processed.FFmpeg is a very robust tool for different types of media operations, including extracting images from a video. keyint_min value should be greater than no. Then for each processed series, run ffmpeg -framerate X -i procN-%d.png -c:v libx264 -keyint_min 1000 -x264opts stitchable "result\segsN.mp4"

Not directly, but in a roundabout way.įFmpeg's segment muxer can break up a file at GOP boundaries, so running the command below generates a set of videos which each start with a keyframe but contain no other keyframes. I know this is a complex problem so all help is truly appreciated!Ĭan't comment on the soundness of your theory, but here's a way to do it. Second question is that how can I re-encode the video so that it keeps the I-frame positions? ffmpeg -framerate 24 -i frame-%03d.png output.mp4Ībove would make the video out of frames but the I-frame positioning eludes me. So first question is that how can I extract frames with ffmpeg so that it somehow identifies each frame type on the filename? ffmpeg -i C:\test.mp4 -vf select='eq(pict_type\,I)',setpts='N/(25*TB)' C:\testTemp\%09d.jpgĪbove gives you i-frames but I haven't figured out how I can get this to export all the frames and to put the type on the filename? What I've figured out so far is that I need to find a way to extract all frames from a video while knowing which ones are I-frames, then do a filter on all the frames, and then re-encode the video back together with minimum quality loss. Another avenue would be to try with h265 because it's more robust frame prediction capabilities. My theory is that given how h264 uses I-frames to get the reference and rest of the frames are "non-essential", if I can find apply the high quality A mode on I-frames and B mode on other frames, I should be able to leverage h264's own compression to get the result without having to use filter on A mode to every frame. Filter has two modes, A mode is very computationally heavy but produces production ready quality and B mode is fast but produces less than stellar quality. Due some restrictions outside my control I have to use proprietary filter that works only on images and not video. I have a research project where I need to apply very, very computationally heavy image filters on a h264 video.
