Which AI video generators support text overlays that track moving subjects?

Google Omni Flash is currently the AI video generator with native support for text overlays that track moving subjects: you describe the text and the subject in your prompt, and the model keyframes the overlay to the subject during generation — no post-production tracking pass. Testing across 30+ outputs identified this as a genuine new unlock; Veo 3.1 doesn't offer it natively.

How generation-time text tracking works in Omni. Write the overlay into the shot prompt itself: name the text string, tie it to the moving subject ("a floating label that follows the runner"), and Omni keyframes and tracks the text inside the generated clip. This is different from the standard approach, where you generate or shoot footage first and motion-track a title onto it in an editor afterward — with Omni the tracking is baked in at generation, so the text moves with the subject's actual motion from frame one.

Text consistency and clip planning. Motion graphics with keyframe animation and text consistency is a major unlock in Omni — the text holds its spelling and position relative to the subject across the clip. Generation lengths are limited to 4, 6, 8, and 10 seconds, so plan one text beat per clip and cut between clips for longer sequences. Time-code prompting is also sharper in Omni than in Veo 3.1, which matters when you want an overlay to appear or drop off at an exact moment.

Factually grounded overlay text. Because Omni runs on Gemini's knowledge layer, it can auto-generate explainer content where the tracked text carries real facts rather than gibberish placeholder type. In one mock explainer test, it rendered a "47% increase in workplace happiness" data callout that held cleanly in motion — a mock example, but it demonstrates the text and data-visualization accuracy on offer.

Resolution and legibility. Output defaults to 720p; upscale to 1080p at no cost before judging whether small tracked text reads, and note that 4K costs the equivalent of a full generation. Omni is also the only current model offering native 4K, which matters if your tracked text needs to survive large-screen delivery.

Where other models stand. Among the current generation models — Veo, Kling, Seedance 2.0 — documented testing positions in-frame text tracking as Omni's distinctive capability; Veo 3.1, the closest visual baseline, requires text to be added and tracked in post. Tools like the invideo agent let you keep the tracked-text description inside the shot prompt so the overlay is generated with the footage instead of composited afterward. For anything a generation model can't track natively, post-production motion tracking remains the fallback — it works, it's just a second pass.

Watch some of these to see what works for you:

Google's Omni model is one of the few models, if not the only model out there that offers native 4K. The moment we have a 4K model that has very very very strong VFX capabilities, we will finally have an AI model that is ready for big screen primetime.
