In a post in the YouTube help forum, video creators will not be able to access the site’s Video Editor or Photo slideshows as of September 20, 2017.
The reason for this feature’s closing, according to YouTube, is because of limited usage.
“We’re retiring them to focus our efforts on building new tools and improving on other existing features,” writes the forum community manager who penned the post.
According to YouTube, even though the Video Editor feature will go away after September 20, any videos that were published using the tool will not be affected. Video creators will be able to perform editing tasks (such as blurring, filters and trimming) using the Enhancements feature found within the Video Manager.
If you have any videos using the editor, it’ll be a good idea to download them so you can get the original files, so you can remix them into a new video.
