SSubmagic Try it →Watch full video →Collin Michael Tutorials · Dec 2025

Demo summary

The creator demonstrates searching for and inserting stock footage from Storyblocks and free libraries directly into the video timeline.

Step-by-step

Select the specific section of the video timeline where you want to add B-roll.
Click on the B-roll tab in the side menu.
Enter a search term in the search bar to find relevant footage.
Select a video from either the free library or the premium Storyblocks library.
Adjust the position of the footage if necessary to fit the frame.
Preview the clip to ensure the B-roll aligns with the audio.

Options

Choose between free video libraries or premium Storyblocks content
Add images instead of video B-roll
Add transitions between the main footage and the B-roll
Adjust the framing for 16:9 or long-form stock footage

Tips

Split your content into different sections so the B-roll doesn't play over the entire video.
Match the B-roll specifically to the keywords or topics being discussed in that segment of the audio.

Highlights

“I can easily click on that... that looks great.”
