I changed a video’s effects to negative. Now I want to save the modified video. How can I do this?
I tried to save the file, but the changes did not show up when the file was played in another media player.
Note, this will not apply the changes you have selected in the preferences dialog to the file. You will need to look up the command-line format of the effects that you wish to apply. For example, to rotate the video 180 degrees, use
:transform-type=180
You can find a comprehensive list of the command-line filters here, though most are presented in the global format (starting with --
), which you need to convert to the stream-specific format (which start with :
instead).
After some thought, I think HandBrake is a better tool for this. There is a "Dimensions" tab. You can set the desired cropping for each side, go to the preview tab, and when it looks good, hit "Start Encode". Much easier than figuring out command-line parameters.
