API companies: the snippet is Ideogram or overlay
Veo will not typeset a curl command reliably.
API companies: the snippet is Ideogram or overlay. Veo will not typeset a curl command reliably. A cinematic 8-second clip with native audio is a product video. A curl line is typesetting. Do not ask one generate to be both.
Developer ads fail on the frame where the endpoint appears. Viewers who would never notice a slightly wrong sky will notice a hallucinated flag, a missing quote, or a path that is not the path in the docs. That is not a "prompt harder" problem. It is the wrong object.
Veo is the plate, not the terminal
Veo 3.1 is in the catalog as short cinematic video: native audio, official 4K tier, 4 / 6 / 8 second clips, 16:9 / 9:16 / auto. Features named cinematic, enhanced, premium. That is the atmosphere pass — office, rack, cursor blink as texture, a hand on a laptop whose screen you will replace.
It is not a monospace renderer. Video models redraw letterforms every frame. A curl command is a long, specific string. On-screen text in generated video is the rule: text you cannot afford to get wrong should never be generated inside the frame.
Write the Veo prompt as a clean plate. Dark terminal, no readable command, no invented hostname. Then put the real snippet on later.
Ideogram is the snippet still
When the ad is the command — a docs GIF, a launch card, a LinkedIn still that has to be copy-paste true — generate a still on a model whose catalog job is text.
Ideogram V4 is text-to-image at 6 credits. Description: high-quality images, posters, and logos with accurate text rendering. Features named: text-to-image, text rendering, posters & logos. Aspects: 1:1, 16:9, 9:16, 4:3, 3:4. Proofread the output against the docs the way you proof a print deck. One wrong flag in the still becomes every downstream frame if you then animate it.
Use that still as the card, or as frame one of an image-to-video pass if you need a slight camera move. Do not start the snippet in Veo and hope the 8s hold.
Text-to-image is the still surface. The video generator is a different door.
Overlay when the command must stay yours
Legal, docs, and versioning will change the line. Overlay is how you change it without regenerating the office.
Add timed text overlays burns several lines you write, each with start_sec / end_sec. That is the sequence: comment, then the curl, then the 200. It is not transcription. Font, size, and color are set once for the set. For a single badge that holds the whole clip — POST /v1/jobs — add a text overlay is the one-line tool.
Type the command in the editor. Do not paste a production secret into a prompt. A docs-safe example is enough; the point is glyph control, not a live key.
If you need the terminal to look like a terminal, Ideogram the chrome, overlay the payload. Two layers. One bill. Veo stays the room.
FAQ
Can Veo 3.1 render a short curl if I put it in quotes?
Not as a production system. 4 / 6 / 8 seconds of native-audio cinema is the row. A quoted command is still in-frame type across every frame. Overlay or Ideogram.
When is Ideogram better than overlay?
When the snippet is the whole graphic — poster, docs card, thumbnail — and you want the type integrated with the layout. Overlay wins when the picture already exists and the command has to be editable.
Does timed overlay transcribe a demo recording?
No. You write every line. If someone spoke the explanation, add captions is the speech tool. The curl is still your text.
Why not screenshot a real terminal?
You can, and many teams should. This page is for the week you do not have a clean capture and are about to spend Veo credits inventing one. Screenshot, Ideogram, or overlay. Not Veo-as-typesetter.
