FFMPEG no such file or directory

[Trekmeister]

I have read a number of topics related to ffmpeg and no such file or directory and still cannot figure out why this is happening

I am trying to extract individual frames from an MKV using the following command C:\Users\me\Desktop\Original\ffmpeg -i video.mkv video%04d.png -hide_banner

If I use C:\Users\me\Desktop\Original\ffmpeg, ffmpeg fires up within cmd prompt
If I use C:\Users\me\Desktop\Original\video.mkv; the mkv will player in media player

However when I try to get ffmpeg to start splitting the mkv, I get file not recognised

I have the 64bit version of ffmpeg installed, I have added ffmpeg to environmental variable path and used ffmpeg -codecs in cmd but still the same issue
I've also used italics around the file name to no avail

I have no idea why/where I am going wrong. It used to work on my last pc without fault which was much more dated

Any solutions much appreciated

open an command window (cmd)
Enter g.e. ffmpeg -ss 01:44 -i "D:\videos\yourvideo.mkv" -t 00:04 "D:\Images\yourvideo_%03d.png"
This extracts all images of the video from 01:44 for a duration of 4 seconds as png files.
(D:\videos is the path to your video file, D:\Images is the path to the generated images; this path must exist. Adapt both paths to your situation).

ffmpeg -ss 00:00:09 -i "inputvideo" -vframes 1 output.jpg
This will extract 1 frame from inputvideo at 9 seconds.

Specify the full path to the input file. If there are spaces anywhere in the path use quotes around the path.

C:\Users\me\Desktop\Original\ffmpeg -i "c:\full path\to\video.mkv" video%04d.png -hide_banner

The default folder when you start a CLI is c:\users\username, where username is your account name. That's where the output files will be if you don't specify an output path.

Awesome, worked a treat, thanks very much indeed
