I am trying to convert a MP4 video file into a series of jpg images (out-1.jpg, out-2.jpg etc.) using FFMPEG with,
mkdir frames ffmpeg -i "%1" -r 1 frames/out-%03d.jpg However I keep getting errors like,
[image2 @ 00000037f5a811a0] Could not open file : frames/out-C:\Applications\FFMPEG\toGIF.bat3d.jpg av_interleaved_write_frame(): Input/output error frame= 1 fps=0.0 q=5.9 Lsize=N/A time=00:00:01.00 bitrate=N/A video:63kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown Conversion failed!
If I take out the %03d part, the conversion works but it only outputs the first frame and the program stops with error.
How can I correctly extract all the frames of the video with FFMPEG?

Two quick-and-dirty ways: Use the FFmpeg executable with the seek option. You'll need to convert to a time first, e.g. if I want frame 150 and my video is 29.97 FPS the command will be ffmpeg -ss 00:00:05.01 -i myvideo. avi -frames:v 1 myimage.
Follow these steps to extract frames from mp4 using FFmpeg. Step 1. Add FFmpeg to your Windows path, and open the Command prompt. Step 2. Type the following command. ffmpeg -ss 04:00 -t 03:00 -i yourvideofilename.mp4 -r 1 image-%03d.png

We use fast seeking to go to the desired time index and extract a frame, then call ffmpeg several times for every time index. Note that -accurate_seek is the default , and make sure you add -ss before the input video -i option. Note that it's better to use -filter:v -fps=fps=... instead of -r as the latter may be inaccurate.
Use
ffmpeg -i "%1" frames/out-%03d.jpg A sequence of image files don't have a framerate. If you want to undersample the video file, use -r before the input.
Edit:
ffmpeg -i "C:\Applications\FFMPEG\aa.mp4" "frames/out-%03d.jpg" If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
