How To Remove Black Bars On YouTube Videos

I have been dabbling in the video recording, editing and publishing field lately. One of the latest things that I had to get my head around was a black bar problem on YouTube. Depending on the original video that you upload, you may see black bars horizontally or vertically. That’s pretty bad for the viewing experience in my opinion. Problem is: Since you have already uploaded the video, you might not want to re-reprocess it locally to update it again. Especially not if the current video has already received comments, views or links.

YouTube has added commands to the video hosting platform to correct the aspect ratio of already uploaded videos. While the end result won’t be as pretty as re-processing the video, it will save the director the troubles of doing that.

Take a look at the following two screenshots. The first shows a video that I have recentlyuploaded to YouTube. It has black bars on the right and left. The second screenshot shows the same video after making the changes on YouTube. It is now stretched. The bars are gone.

YouTube some time ago has added commands that are executed when added to a video’s tags. Commands are available to get rid of black bars on videos. Here are all commands that you can utilize.

• yt:crop=16:9 – This tag crops the video. It basically means that the player zooms in on the video so that contents at the borders may be not visible anymore.
• yt:stretch=16:9 – Stretches the video into a 16:9 format. This is the tag I have used for the video. Depending on the size of the black bars, it may make the video look distorted.
• yt:stretch=4:3 – Another stretch command. This stretches the video into a 4:3 format instead.
• yt:quality=high – Sets the video to play in high quality, if a hq version of the video has been uploaded by the owner.

You can apply tags by clicking on the Edit button next to the video in your YouTube videos listing.
