This batch script trims a user-defined amount of time from the end of all .mp4 videos in the folder where the script is located and saves the trimmed videos to a subdirectory called output_dir.

• Allows the user to input the trim time in the format hh:mm:ss, mm:ss, or ss.
• Automatically adds a minus sign to the user’s input to trim from the end of the video.
• If ffmpeg.exe is not found in the script’s directory, it will attempt to use ffmpeg from the system’s PATH.

1. Place the batch script in the folder containing the .mp4 videos you want to process.
2. Run the script. It will prompt you to enter the amount of time to trim from the end of each video in the format hh:mm:ss, mm:ss, or ss.
   • Example: 07:07 is 7 minutes and 7 seconds, 07:07:07 is 7 hours, 7 minutes, and 7 seconds.
3. The script will create an output_dir subdirectory if it does not already exist.
4. It will process each .mp4 video, trim the specified amount of time from the end, and save the trimmed videos to the output_dir.

Note: If ffmpeg is not located in the same directory as the script, make sure that the path to ffmpeg is added to the system PATH environment variable.

The easiest way is to download the batch-lossless-cut.zip, extract the files into the folder with the videos you want to trim, and run batch-lossless-cut.bat

• FFmpeg must be installed or included in the same directory as the script, or it should be available in the system PATH.

If you are using Method 1, you will need to download and install ffmpeg separately. You can either:

1. Add ffmpeg to the same directory as the batch script.
2. Or, add ffmpeg to your system’s PATH environment variable so it can be used globally.
