This small application adds some bytes to selected files. It means that you can upload the same video on your YouTube account 100 times and editing the video won't be required.
You can run the app and generate 100 different video files. They will be unique.
The content remains exactly the same.
Bytes changes several of the bytes of the file so that YouTube sees a unique video.
You could make 100 copies of the same video and each would be unique in the YouTube algo.
Upload each with a different title and description and viola.. 100 uniques making you money.
