Trim Video Through YouTube Video Manager
Though YouTube Video Editor is disabled since September, 2017, you can still edit video through YouTube site, but merely in Video Manager, where you can auto-fix lighting and color, apply slow motion, rotate the video view, apply fliters, trim out parts of your video and custom blurring etc. But here we're talking about YouTube video trimming.
a. Just log into your YouTube account and click Upload icon to upload video to YouTube.
b. Once your video is loaded, click on Video Manger icon before finally publishing the video to YouTube. By the way, you're able to edit your YouTube published videos in the Video Manager page as well.
c. Click on the Edit icon, then tap on the Enhancement button on the result page.
d. Here you'll see a Trim icon, click on it and move the start and end modules on the timeline to shear out the video parts. If you want to split video into clips, you can click on the Split button as you've moved the blue arrow line to the cut-off point. After you've done, click the Done button.
e. Click Save. If you want to create a new video with these enhancements, click Save as new video.
The Limitations of Trimming YouTube Video for Free on YouTube
Yes, with above steps, you can cut YouTube video smoothly on Mac or Windows without installing any extensions or third-party software. However, Video Manager is not omnipotent and it has some limitations. Firstly, you cannot crop YouTube videos, merge several video clips into one, or some other further editing, which persuade you to turn to a professional yet free video editor for Mac and Windows. You can only edit and trim your uploaded video which hasn't received over 100,000 views. If you choose to upload your video to YouTube before trimming, it will cost you a lot of time and consume too much bandwidth, especially for 4K UHD higher resolution and large size videos. Worth yet, trimming video free with YouTube site gets more zigzag comparing to the previous intuitive editing page.
