Devtools: terminal look is a caption family, not a generate
Use a terminal preset. Do not ask Veo to invent code.
Use a terminal preset. Do not ask Veo to invent code. The look is furniture on a real session. It is not a scene you prompt into existence.
Developers evaluate a tool by watching it fail as much as by watching it work. Developer relations already names the split: architecture and data flow can be generated; code and terminal output should be the real thing, because someone will try to reproduce it. A cinematic fake REPL is the fastest way to lose that audience.
Show the real session
Film the terminal. Errors included. Cut the pauses. Do not cut the failure every user will hit on their own machine.
The generate aisle is for the parts a screen cannot show: request lifecycle, a box-and-arrow of what happens between services, a changelog beat with no UI. Those are explainers. They are not a substitute for the session.
Veo 3.1 is a cinematic row: native audio, 4 / 6 / 8 second clips, 4K tier. It will invent a glowing terminal that looks like a product film. It will also invent commands and output that do not exist in your CLI. That is not a prompt miss. It is the model doing scene work when the pixels are supposed to be a repro.
Terminal is a caption preset
The “terminal look” on a shipping clip is a caption family, not a generate. Add captions burns VEED presets onto speech you already recorded: 21 BASIC looks at 1×, 9 DYNAMIC looks at 2×. Terminal sits in the DYNAMIC row with glass, whisper, glide, fusion, handwritten, and the backdrop variants. Transcription and timing are the same work across every preset. The tier changes the furniture and the charge, not the accuracy.
Record the real demo. Burn terminal on the spoken line if that is the account furniture. Preview a few seconds with preview_caption_style before you pay the full render — DYNAMIC is 2×, and picking it from a thumbnail is how you caption a long read as a music video of a stack trace.
Caption styles is the other furniture catalogue: 45 Caption Studio presets, nine families of five. Those are Studio families (classic, paper, ink, and the rest). They are not VEED’s terminal row. Pick one system and stay there. Mute-test the preset. If the first word sits on the command people need to read, the furniture is fighting the demo.
Do not typeset the CLI with a picture model
Ideogram V4 is the catalog row for words in a still: 6 credits, text rendering, posters and logos. That is a lockup or a launch poster. It is not a REPL. Asking it to render thirty lines of plausible TypeScript is how you ship a screenshot nobody can run. Overlay the real output, or film it.
If you already have the lockup in vector, do not regenerate it. Composite it. Your CLI output already exists as a file. Put that file on screen.
The pipeline that survives a technical audience: capture the real terminal; cut so the failure is still in the file; burn one caption family; generate only the diagram the screen cannot show. Veo does not belong in step one. Ideogram does not belong in step one. A preset does.
FAQ
Can I prompt Veo to “match my product’s CLI theme”?
You can. You should not ship it as the demo. Theme is colour. The audience is reading commands. Invented output is a broken repro even when the colours match. Film the session; put the theme in captions.
Is the VEED terminal preset the same as Caption Studio?
No. Terminal is a DYNAMIC VEED preset on the captioning tool, billed at 2×. Caption Studio is 45 presets in nine families on the styles index. Do not mix them inside one series.
When is Ideogram the right row for a devtool launch?
When the deliverable is a poster, a wordmark, or a short line that has to read as written in the still. Not when the deliverable is a screenshot of the product. Screenshots are captured.
Do I still caption a silent terminal recording?
If nobody is speaking, transcription has nothing to burn. Use a text overlay you wrote for the hook, or leave the session as the picture. Do not run a captioner on silence.
