2. YouTube Studio's built-in features

YouTube Studio itself provides some bulk editing capabilities within the content section.

Features: Select multiple videos and edit various properties simultaneously, such as title, description, tags, visibility, and more.

Limitations: While useful for basic edits, it may not offer the advanced functionalities found in dedicated third-party tools. 

3. General video editing software

Some traditional video editing software can be adapted for batch editing if you apply the same changes to multiple projects or use specific features like export presets.

Software Examples: Adobe Premiere Pro, Final Cut Pro X, DaVinci Resolve, iMovie, Wondershare Filmora, etc.

Considerations: These tools may require more manual work to achieve true "mass editing" compared to solutions specifically designed for batch processing. 

In summary

The best choice for you will depend on the specific types of edits you need to perform and the scale of your YouTube content. For quick, repetitive tasks like updating descriptions or tags, YouTube Studio or dedicated tools like TubeBuddy are excellent options. For more complex, template-based bulk video creation, platforms like Plainly or Creatomate might be more suitable.
