Is there any simple way to find the fps of a video in ubuntu? In windows I use Gspot to find out all the information about a video file. But in ubuntu I find it very difficult to find out this basic information. Any help is appreciated.

  • This is not possible, because not all video files have a "fps" (because VFR encoding exists). – fkraiem Oct 17 '17 at 1:58
  • VFR videos still have an average frame rate - whether or not this is useful depends on the application. – thomasrutter Dec 12 '17 at 0:56

This will tell you the framerate if it's not variable framerate:

ffmpeg -i filename

Sample output with filename obscured:

Input #0, matroska,webm, from 'somerandom.mkv':
  Duration: 01:16:10.90, start: 0.000000, bitrate: N/A
    Stream #0.0: Video: h264 (High), yuv420p, 720x344 [PAR 1:1 DAR 90:43], 25 fps, 25 tbr, 1k tbn, 50 tbc (default)
    Stream #0.1: Audio: aac, 48000 Hz, stereo, s16 (default)
ffmpeg -i filename 2>&1 | sed -n "s/.*, \(.*\) fp.*/\1/p"

Someone edited with one that didn't quite work the way I wanted. It's referenced here
Additional edit...If you want the tbr value this sed line works

sed -n "s/.*, \(.*\) tbr.*/\1/p"
  • I needed to use tb instead of fp in the one-liner. Seems not all video files report fps but all autput something like tbr tbc which has the same value. – sup Mar 11 '12 at 17:28
  • valid, but the one-liner from the edit output-ed the tbc value not the tbr value in this particular set of output. something to consider on why i changed it...I'ld rather it fail in a really noticeable way than a way that isn't noticed at all. – RobotHumans Mar 11 '12 at 20:10
  • I think sed -n "s/.*, \(.*\) tbr.*/\1/p misses " in the end, no? – sup Mar 12 '12 at 19:24

    ffmpeg is not deprecated, avconv came from a branch of ffmpeg and to avoid confusion for those using the ffmpeg alternative the fake branch was marked as deprecated to let those users know that the version they were using was changing. your comment is misleading and could cause users to waste time researching this – Chris Apr 20 '16 at 14:07

    What if it is variable frame rate? – 0xcaff Dec 24 '16 at 0:28

ffprobe -v 0 -of csv=p=0 -select_streams v:0 -show_entries stream=r_frame_rate infile

Result:

2997/100

    This is probably the best answer in that it gives the EXACT frame rate (in the example 24000/1001 = 23.976023976) – ntg Jan 20 '16 at 12:30

    sometimes i get 0/0 depending on the format – Daniel_L Feb 13 '17 at 21:53

    Depending on what you want, this either works or doesn't. It reports the framerate of the encoding, but not the actual framerate of the video. For example, a 30fps video encoded into 60fps will report 60fps but will still be 30fps in actual output. – Harvey Jul 20 '17 at 17:16

    This didn't work if the video stream is not the first stream, you will get 0/0 if it looks at an audio stream. I will edit to put -select_streams V:0, which will select the first moving video stream. – Sam Watkins Sep 21 '17 at 6:44

    @SamWatkins's complement is important. Without it, the command given output 0/0. – jdhao Jun 6 '18 at 5:12

Here is a python function based on Steven Penny's answer using ffprobe that gives exact frame rate

ffprobe 'Upstream Color 2013 1080p x264.mkv' -v 0 -select_streams v -print_format flat -show_entries stream=r_frame_rate
import sys
import os
import subprocess
def get_frame_rate(filename):
    if not os.path.exists(filename):
        sys.stderr.write("ERROR: filename %r was not found!" % (filename,))
        return -1         
    out = subprocess.check_output(["ffprobe",filename,"-v","0","-select_streams","v","-print_format","flat","-show_entries","stream=r_frame_rate"])
    rate = out.split('=')[1].strip()[1:-1].split('/')
    if len(rate)==1:
        return float(rate[0])
    if len(rate)==2:
        return float(rate[0])/float(rate[1])
    return -1

The alternative to command line, is looking at the properties of your file via context menu in Nautilus (graphical file manager). For audio/video files you get an additional tab there with extra informations.

This is a python script to do this using mplayer, in case anyone is interested. It is used path/to/script path/to/movie_name1 path/to/movie/name2 etc

#!/usr/bin/python
# -*- coding: utf-8 -*-

import subprocess
import re
import sys

pattern = re.compile(r'(\d{2}.\d{3}) fps')
for moviePath in sys.argv[1:]:
    mplayerOutput = subprocess.Popen(("mplayer", "-identify", "-frames", "0", "o-ao", "null", moviePath), stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()[0]
    fps = pattern.search(mplayerOutput).groups()[0]
    print fps
0

You can right click the target file, Properties, Audio/Video but you will not get the exact framerate. To get a precise framerate you can install MediaInfo.

Just in case someone stumbles upon this... you can of course use input arg as the path ;)

import numpy as np
import os
import subprocess

def getFramerate():
    con = "ffprobe -v error -select_streams v:0 -show_entries stream=avg_frame_rate -of default=noprint_wrappers=1:nokey=1 D:\\Uni\\Seminar\\leecher\\Ninja\\stream1.mp4"

    proc = subprocess.Popen(con, stdout=subprocess.PIPE, shell=True)
    framerateString = str(proc.stdout.read())[2:-5]
    a = int(framerateString.split('/')[0])
    b = int(framerateString.split('/')[1])
    return int(np.round(np.divide(a,b)))
0

I usually use exiftool to get info of any file type... For example with command exiftool file.swf I can know the framerate of any swf file, something I cannot achieve with ffmpeg

-1
ffprobe <media> 2>&1| grep ",* fps" | cut -d "," -f 5 | cut -d " " -f 2

    explain what it will do ? – rɑːdʒɑ Aug 16 '13 at 12:56
