framerate - How to find frames per second of any video file?, To get a precise framerate you can install MediaInfo. file.swf I can know the framerate of any swf file, something I cannot achieve with ffmpeg. To change the output frame rate to 30 fps, use the following command: ffmpeg -i <input> -filter:v fps=fps=30 <output> If the input video was 60 fps, ffmpeg would drop every other frame to get 30 fps output. Verifying frame rate changes
get video fps using FFProbe, I found calculate fps in another method that is.. String query = "ffmpeg -i foo.avi 2>&1 | sed -n 's/.*, \\(.*\\) fp.*/\\1/p' > fps.txt"; String[] command ffmpeg -i 00000.avi -map 0:v:0 -c copy -f null -y /dev/null 2>&1 | grep -Eo 'frame= *[0-9]+ *' | grep -Eo '[0-9]+' | tail -1 This should be fast, since no encoding is being performed. ffmpeg will just demux the file and read (decode) the first video stream as quickly as possible.
Changing the frame rate, ffmpeg can be used to change the frame rate of an existing video, such was 60 fps, ffmpeg would drop every other frame to get 30 fps output. the commandline version for the ffmpeg fps I use is ffmpeg -i yourfilenamehere.avi -vcodec copy -acodec copy -f null /dev/null 2>&1 | grep 'frame=' | cut -f 2 -d ' ' in linux or ffmpeg -i yourfilenamehere.avi -vcodec copy -acodec copy -f null /dev/null 2>&1 | findstr 'frame=' in windows (xp upwards) – GMasucci Dec 17 '13 at 15:57

How do I get the number of frames in a video on the linux command , I've found that mediainfo --fullscan inputfile | grep "Frame count" works nicely for most files. Debian based systems can install it with apt-get install mediainfo. You speak about frame count then frame location, this is a bit incoherent. frame count and frame location are totally separate items. I never saw any frame count 0-based, a frame count is a count, so "1" means that there is 1 frame in the file (i.e. only frame 0 if your frame location scheme is 0-based, so time code "00:00:00:00" is the only

ffmpeg limit number of images converted to video, You can use -frames:v : ffmpeg -i img_%4d.jpg -frames:v 500 output.mp4. As an example use of these, I did something like this to create images from all frames, beginning at the tenth second, and continuing for 5 seconds: ffmpeg -i input.dv -r 25 -ss 00:00:10 -t 00:00:05 -f image2 images%05d.png As Victor suggested the FFmpeg documentation is a good place to start for an overview of available options.
ffmpeg, You do this by stating the number of frames you want: -vframes 100. So effectively it is in your case: ffmpeg -start_number 1 -i test_%d.jpg -vframes 100 -vcodec Number of reference frames on output for ffmpeg-qsv is 3. But for ffmpeg-vaapi by default - 2 and I cannot set it through -refs 3 option. May be I'm wrong, but I cannot find any other cmd-line options for reference frame number.
How to extract a fixed number of frames with ffmpeg?, You could use the thumbnail filter. It picks one representative frame from every set of n frames (default is 100). So, if your source video is 10 The number of frames is correct so my output should change from 20 minutes at 30fps to 25 minutes at 24fps. Everything else should remain the same. Try as I might everything I try with ffmpeg converts the frame rate but changes the number of frames to keep the same duration or changes the duration without altering the framerate.
Fetch frame count with ffmpeg, This is horrible, and stupid, and slow, but seems to work: ffmpeg -i foo.avi -vcodec copy -f rawvideo -y /dev/null 2>&1 | tr ^M '\n' | awk '/^frame=/ {print $2}'|tail -n 1. Add the -skip_frame nokey option to only count key frames. ffmpeg: Count the number of frames. If you do not have ffprobe you can use ffmpeg instead: ffmpeg -i input.mkv -map 0:v:0 -c copy -f null - This is a somewhat fast method. Refer to frame= near the end of the console output. Add the -discard nokey input option (before -i) to only count key frames.
How do I get the number of frames in a video on the linux command , information like frame width and frame height is present there. This has been covered before, and the consensus solution is (minor variations on) the following command line: ffmpeg -i input.MP4 -vf "drawtext=fontfile=Arial.ttf:text='%{frame_num}':r=25:x=(w
Find out Video Resolution and Frame Rate using VLC, How do I count the number of frames in a video in Python? My idea is to grab a still from the video, cut the image and create a mask, feed the video and mask into ffmpeg, use a filter to apply the mask over the video, calculate the difference between the current frame and mask and try to detect if the entire image is black which would indicate that the image is present in the frame.

Extract specific video frames, ffmpeg in Matlab. However, I do not have access to Matlab nor I am that competent using it. Using the command prompt and VLC.
