Créer des vidéos générées par IA à partir de ChatGPT : un processus pratique

You can generate AI videos from ChatGPT by using it to develop the brief, script and shot prompts, then sending those instructions to a video generator. A supported connection can handle that handoff inside the conversation. The video model still renders the footage, and its own access rules, settings and costs apply.

The useful starting point is a small, specific scene: a desk lamp switches on, a camera moves a little, and the product stays recognizable. Get that shot right before asking for a finished advertisement. A precise brief gives you something you can inspect and improve..

What ChatGPT does in an AI video workflow

There are three different jobs hiding inside the phrase “make a video.” A chat assistant organizes the idea and writes instructions. A video model turns those instructions and any supported references into moving images. An editor assembles the usable shots, narration, captions and final export. One product can connect several of these jobs, but the responsibilities still matter.

For the broader capability question, the ChatGPT video creation overview explains the role of the chat interface. The workflow below concentrates on getting from a usable brief to inspectable footage.

Choose a connected or manual route

Route A: A supported video connection inside ChatGPT

Higgsfield advertises a ChatGPT connection that accepts text and references, runs its creative models and uses Higgsfield credits. Its instructions say to add the Higgsfield plugin and sign in with a Higgsfield account. Follow the connection page and the controls actually available in your own account.

Le Higgsfield setup guide also says availability can depend on plan, region and workspace settings. We verified those published instructions, but did not test an authenticated ChatGPT connection. Do not assume that a missing menu means you have done something wrong, or that every account exposes the same controls.

Once a connection is available, request the proposed model, references, aspect ratio, duration and credit estimate before starting. After submission, keep the task identifier. A message saying a job is queued is not the finished video.

Route B: Copy the shot prompt into a video generator

Use ChatGPT for planning, then paste one shot prompt into your chosen generator. Attach references through that tool’s upload control and select its supported settings. This route is straightforward when a connection is unavailable or when you want to inspect the generation controls yourself.

GlobalGPT offers text and video tools in one workspace. You can develop the idea with a text model, open the video tool and transfer the approved prompt. This is a separate platform workflow; it does not establish that GlobalGPT is a native ChatGPT video connection.

Select a generator for the shot you need: reference support, controllable movement, audio, output size and cost are more useful criteria than a generic “best” label. The Comparatif des générateurs de vidéos basés sur l'IA provides additional selection context.

A dated warning for Sora API projects

As of September 7, 2026, OpenAI lists Sora 2 and the Videos API as deprecated, with shutdown scheduled for September 24, 2026. Le official OpenAI deprecation notice names the affected API and model IDs. Avoid choosing that API as the foundation of a new long-term workflow. This notice concerns the named API products; it does not establish the status of every consumer app or third-party route.

How to generate AI videos from ChatGPT in five steps

1. Define the result before writing the script

Specify who will watch, where the video will appear and what one thing the viewer should understand. For a desk-lamp product video, the goal might be to show a useful pool of light on a compact workspace. That is a visible benefit. Battery life, brightness ratings and discounts require actual product facts.

Set the final edit length and orientation here, but leave room for the generator’s supported clip lengths. A 15-second edit can use several shorter clips. Writing “15 seconds” in a prompt cannot create a duration setting that the tool does not support.

2. Turn the brief into small, observable shots

Give each shot one main action. A light switching on, a page turning and a final product hold are easy to evaluate separately. Asking one short clip to establish the room, introduce a person, demonstrate a product and deliver a sales pitch makes failures harder to isolate.

These times describe an editing plan, not measured render performance or a promise of three matching generated clips. For a real product, carry an approved product reference into every supported generation. The two tutorial videos are separate illustrative concepts, not a matched campaign or a product-identity test.

3. Write a prompt that describes the shot

Use a clear order: subject, action, setting, framing, camera movement and lighting. OpenAI’s video documentation makes a useful distinction: the prompt describes the scene, while parameters such as size and seconds set the output format. This remains a helpful way to organize a brief even when you choose another generator.

Keep the constraints connected to a visible requirement. “Whole lamp visible” is testable. A string of labels such as “award-winning, 8K, cinematic masterpiece” does not fix an unclear action, and writing “8K” does not set the export resolution.

Model-specific controls need model-specific instructions. The Veo 3.1 prompt techniques provide one example of adapting a general shot brief to a particular generator.

4. Set references, cost and output controls

Upload the image file through the generator or the supported connection. A reference filename written inside ordinary prompt text is not proof that the tool received the image. Confirm that the request actually includes it.

For product continuity, begin with one approved reference and modest motion. The Guide de conversion d'images en vidéo pour le modèle Kling explores reference-led animation. Exact input types and limits still depend on the model and route you use.

Check the aspect ratio, supported duration, output size and audio option, then request one clip. Keep its task ID and the exact prompt. Wait for the result before launching variations; a slow response alone is not evidence that the job failed.

5. Inspect, revise once, then edit

Watch the whole clip at normal speed, then inspect the beginning, middle and end. The first frame can look convincing while a base bends, a hand loses contact or the light direction changes later. Identify one concrete defect before rewriting the prompt.

After selecting usable shots, trim them to the final pacing and add text in the editor. Keep claims, spelling, subtitles and the call to action editable. Listen to every audio track before adding music or publishing a voice line.

When a specific model is the next step, the Seedance 2.0 prompt examples offer additional prompt structure. That link refers to the named model version; its settings should not be assumed to apply to a different release.

Hands-on: from GPT-6 Astra to a video in GlobalGPT

We tested this workflow in a signed-in Espace de travail GlobalGPT on September 7, 2026. GPT-6 Astra prepared the shot instructions. The video tool provided its own model selector and rendering controls. Here is the sequence we followed, including a handoff detail that is easy to miss.

1. Select GPT-6 Astra and describe one shot

From Home, select AI Models and GPT-6 Astra. We asked for a prompt under 90 words describing a silver desk lamp with a coral base, one switch-on action, a fixed camera and stable geometry. We also asked for the requested aspect ratio and duration to be listed separately, conditional on the video tool supporting them.

2. Take the finished prompt to Go to Produce

GPT-6 Astra returned a concise shot prompt and a separate settings note. A Video Generate panel appeared below the response with a Go to Produce control. That control opened the video generator, where the initial selected model was Seedance 2.0 Fast.

Check the transferred text before generating. In our run, the generator received the original question beginning “Help me create one short product video,” including the request to write a prompt. We replaced it with the actual shot prompt from GPT’s answer. Switching video models also cleared the prompt field, so we checked and pasted the finished text again after choosing the renderer.

3. Choose the video model and verify its settings

We selected Seedance 2.5 for the text-only shot, left the optional start and end frames empty, and set 16:9, 5 seconds and 720p using the actual controls. Enhance Prompt and Native Audio were off. Share to community was also off. Selecting a model can change both the required inputs and the available settings.

The Generate button displayed 3,500 Credits for this configuration. We submitted one video request. This is the estimate shown in that account on the test date, not a universal price for GPT planning or every video model. Keep the generation request separate from the text-model response when checking costs.

4. Inspect the completed clip

The completed 5-second clip shows the lamp switching from off to a warm-white glow while the full object remains visible. The brushed-silver body and coral circular base stay recognizable from the opening through the final frame, with a substantially locked composition and no people, logos or generated text. This single result demonstrates the tested workflow, not guaranteed performance on other prompts.

Original video examples: what to inspect

The opening product film and the desk scene below were generated for this tutorial through the GlobalGPT CLI using Grok Imagine video. Their prompts were authored for this article. They illustrate the manual handoff stage, and should not be read as a test of Higgsfield, a ChatGPT connection or one model against another.

• Product film: follow the circular base and curved neck throughout the camera move. Check whether the light switches on as requested.
• Desk scene: watch the hand, paper edge and page landing together. A convincing still frame is not enough.
• Both clips: inspect the full object boundaries, shadow direction, unexpected cuts and final-frame stability.

In these two single-run examples, the product lamp brightens during the opening fraction of a second and stays fully framed during the camera arc. The desk clip completes one page turn with the lamp remaining in place, although its framing drifts slightly instead of staying perfectly locked. Both selected clips are silent 1280 x 720 exports, approximately five seconds long. These observations describe these files only; they are not a model ranking or a guarantee of product consistency.

Can you do this for free, and who charges for what?

Treat planning access and video rendering as separate costs. Access to a chat assistant does not by itself establish a video allowance. A connected provider may use its own credits even though the request was written inside a ChatGPT conversation.

Higgsfield states that generations through its ChatGPT connection consume credits, while Unlimited model access applies to its web app. Its published ChatGPT billing explanation should be read as a rule for that provider and surface. Do not transfer its example credit prices to another model, date or platform.

A simple budget is the sum of your planned renders, plus paid references and finishing work. If you allow two attempts per shot across three shots, that is six possible render charges. It is an arithmetic planning example, not a claim about any provider’s price.

For a connected workflow, use this instruction: “Before each paid generation, show the model, input references, settings and quoted cost. Wait for approval. If a request times out, check the existing task before submitting another.” A prompt requests this behavior; still inspect the tool’s actual confirmation and job status.

Fix the common problems without changing everything

Le AI video generation failure guide gives more troubleshooting context. Distinguish a technical failure from a completed clip that simply misses the creative brief: they require different next steps.

Build longer videos from a shared shot plan

A longer video needs continuity and pacing, not merely a longer prompt. Keep a short continuity sheet with product shape and color, environment, light direction, camera height and reference files. Give ChatGPT this sheet whenever it drafts the next shot.

Cut between related actions, keep space for narration, and use the editor to control the final running time. Where a generator offers an extension feature, check that feature’s current limits and supported inputs separately. Do not assume that every model accepts video continuation.

For a worked approach to assembling short outputs, see making longer videos with Veo 3.1. The general lesson is to plan the sequence first and generate only the shots that sequence needs.

Foire aux questions

Can ChatGPT generate a finished video by itself?

A finished clip requires a video-generation tool. ChatGPT can prepare the brief and prompts, or send a request through an available connection. Confirm which tool rendered the file; a written script or queued job is not a finished video.

Do I need a Higgsfield connection to use ChatGPT for videos?

No. You can draft a script and shot prompts in ChatGPT, then paste them into a separate video generator. A supported connection can automate the handoff, but the manual workflow remains useful when that connection is unavailable.

Is generating AI videos from ChatGPT free?

There is no universal free-video entitlement implied by the workflow. Planning access and video generation may have separate charges. Check the selected provider, account, model, duration and resolution before starting a render.

What should a ChatGPT video prompt contain?

Include the subject, one main action, setting, framing, camera movement and lighting. Keep important constraints specific. Set duration, aspect ratio and output size in the actual tool controls when those controls are available.

Can I turn a product photo into a video?

Use a generator that supports image references, upload the approved photo and describe a small movement. Inspect the whole result for changing geometry and labels. Reference support does not guarantee exact product identity.

Can I create a one-minute video from a ChatGPT script?

Plan the minute as a sequence, generate supported short clips and assemble them in an editor. Keep references, lighting and product details consistent across shots. Do not assume that one request can render the entire minute.

Should I start a new project with the Sora Videos API?

As checked on September 7, 2026, OpenAI lists Sora 2 and the Videos API for shutdown on September 24, 2026. Read the official deprecation notice before selecting that API for a new project; the notice names specific API products.

What should I do when a video request times out?

Check the existing task or asset history before submitting again. A local timeout can happen while the remote generation continues. Keep the task ID so that you can recover a completed result without creating a duplicate job.

Start with one scene you can describe and judge clearly. Use ChatGPT to make the instructions precise, keep the generator’s settings and charges visible, and improve the weakest part of the result before expanding the project.
