>>133575>What do you mean open the command folder in same window as the file?You go to the folder where the video is, hold shift, right-click (not on a file), and 'Open command window here'. This allows you to just use the short file name, instead of the full absolute path.
If for some godawful reason you do want to use the full path, you have to escape each backslash with another backslash, sometimes multiple times, which becomes a huge mess.
One other thing I noticed, you may want to include the '-sn' option. It seems ffmpeg is a little too helpful, and will try to embed softsubs in the mkv, which you usually don't want.
