How to have diagrams drawn behind you as you explain
Upload your take and tell Vizard Agent you want drawings appearing behind you as you speak. Vizard Agent cuts you out of your background, tests the cutout before committing, reads your transcript for the points being made, and draws each diagram in as the words that need it arrive.
What do you type into Vizard Agent?
Say what appears and where it appears. Vizard Agent needs to know the drawings sit behind you rather than beside you, because that decides whether it cuts you out of your background at all, the most consequential technical choice in the whole job. Name a board style, or let the transcript decide what gets drawn.
Prompt
What does Vizard Agent actually do?
An explainer holds attention when the picture is doing something. Diagrams appear behind the speaker as each point lands, so the timing comes from what is being said rather than from a fixed rhythm. Vizard Agent tests the cutout early and measures where the captions sit before placing anything. In the session behind this article it:
- Probed the upload, checked past project notes, transcribed the footage and read the transcript structure.
- Extracted a frame grid to see the framing and the background, and checked the background removal and motion graphics options.
- Tested the cutout on a six-second slice rather than the whole video, then re-checked it with the correct decoder and viewed it by eye.
- Looked for handwriting typefaces so the board would read as drawn, not typed.
- Measured the caption band and located the caption rows numerically, so the drawings stayed clear of the subtitles.
- Rendered the tightened cut and drew each diagram in against the transcript's timing, delivering a 136.87-second portrait video at 1080x1340.
When does this not work well?
Cutting a person out of their background is the hardest part of this format, and the conditions on the day decide how well it goes. Loose hair and glasses are hard edges, busy backgrounds bleed, clothes that match the background vanish, and fast gestures blur. Dense speech can leave no room to draw.
Common questions
Do I need a green screen? No. Vizard Agent removes an ordinary background, though a plain wall gives a cleaner edge.
How does Vizard Agent know what to draw? It reads your transcript and draws to the points being made rather than on a fixed timer.
Will the drawings collide with my subtitles? No. Vizard Agent measures which rows the caption band occupies and keeps the drawings clear.
