I am finally using FFMPEG after using programs like Virtualdub2 but I do need some clarity with some of the commands. Do not get me wrong, the resources that some people sent to me do help but I do some clarity on some of the commands. When you are inputting a video to convert another video, do need to type out the file location or just the video file?

  • If you are in the same folder as the input video you only have to specify the name of the video. Otherwise the whole path + filename + extension, the same is valid for the output video. May 1 '21 at 15:34
  • Are you supposed to put the path + filename + extension in quotes? I heard from another forum that you are supposed to put it in quotes as it is a command line and not a GUI.

  • If the input or output file have spaces in it you have to put it in quotes but if not it is not necessary. For example: ffmpeg -i input.avi output.mp4 but if input or output is something like: ffmpeg -i "My input video.avi" "My output video.mp4" than you have to use quotes... May 3 '21 at 22:57
  • What about the other commands that FFMPEG has? Like the codecs, sizes,etc.?

That's a very general question, you will have to ask for a specific command if you want help since ffmpeg has a loooooot of options. But you can use the following command to get help:

-h      -- print basic options
-h long -- print more options
-h full -- print all options (including all format and codec specific options, very long)
-h type=name -- print all options for the named decoder/encoder/demuxer/muxer/filter/bsf/protocol
See man ffmpeg for detailed description of the options.

If the output is to long you something like: ffmpeg -h |more And it shows a part of the text on the screen everytime you pess a key...

  • I guess I wanted to know how to do the things that you could normally do in editors like Virtualdub or any media editor. Like for example, how do you do PointResize, Lanzcos, Fade In, Fade, Fade Out, etc.?
