How to add motion graphics to a video that already has captions
Upload the video with its captions and logo already burnt in. Vizard Agent measures where the face, the logo and the caption band actually sit across the whole clip, maps the zones left empty around them, and composites transparent motion graphics into those zones at the right moments.
What do you type into Vizard Agent?
Say what the video is about, name what's already on screen, such as the logo and the captions, and give your brand colours. Vizard Agent works out the placement from the footage itself, so the useful instruction is editorial rather than positional. Telling it where to put things is usually worse than letting it measure.
Prompt
What does Vizard Agent actually do?
Vizard Agent treats this as a layout problem before a design problem. Only a few places on the frame are genuinely free, and finding them takes measuring across the whole video rather than guessing from one frame. Every overlay then lands somewhere provably empty. In the session behind this article it:
- Probed a vertical talking-head video, 2160x3840 at 24fps and 169.6 seconds long, with the client's logo pinned top-left and word-level captions burnt in about two-thirds of the way down.
- Transcribed the speech, read the full transcript and studied the layout on a larger frame.
- Checked the motion-graphics tool and its effect library, the client's logo file from a previous project and the brand's colours.
- Measured where the face sat across the video, mocked up the free zones and fixed them as proportions of the frame: beside the head from roughly 13% to 40% down, a banner below the captions from 74% down, and a bar right of the logo at the top.
- Built a beat map of which moment gets which graphic, generated transparent overlays in the brand styling and composited them at the exact timestamps, with nothing overlapping.
When does this not work well?
When the frame is already full. Face, logo, captions and a border can leave nothing, and graphics that fight the existing layout make a video worse rather than better. A moving speaker shifts the safe zones, and low-contrast brand colours disappear into the footage. Vizard Agent tells you when there is nowhere clean to put something instead of dropping it on top of the captions.
Common questions
Do I need to remove my captions first? No. Vizard Agent measures around them and places the graphics elsewhere.
Will the graphics cover the speaker? No. Vizard Agent measures where the face sits before choosing any position.
Are they transparent? Yes. Vizard Agent generates overlays with alpha so your footage plays through.
