VEO 3.1 extend is a 7-second 720p continuation

veo3-1-extend-video is extend-video at 7s, 720p, 40 credits, native audio — it continues a keeper; it is not a new Veo 3.1 generate (4 / 6 / 8s, 4K, 40 credits).

The two Google rows share a number and a family name. They are not the same job. One invents a take. The other buys seven more seconds of a take you already approved. If the outgoing frame is already wrong — wrong face, wrong product, wrong camera height — seven more seconds of that wrongness is the whole purchase.

The 7-second increment is the product

VEO 3.1 Extend Video is Google, category extend-video, native audio on, listed max output 720p, duration locked to 7s, 40 credits. The description is one sentence: “Extend video duration with VEO 3.1.” Qualities on the record include 720p and 1080p; the listed max is 720p. Aspects: 16:9, 9:16, auto. Image is not required because the input is the clip (video_url, one file). You are buying one seven-second continuation per run.

This row does not offer a menu of lengths. supports_durations is the literal 7s. Do not write a three-act sequel into the prompt and hope the model compresses it. Write the next beat that can actually play in seven seconds from the last frame you kept.

The agent surface for the same job is extend a video. The finishing route is extend a video's length. Neither of those changes the catalog: this Google row still meters 40 credits with audio on. The extend glossary is the mechanic. Google’s VEO roster is larger than this one row. This page is only the extend SKU.

Audio is on. You are continuing picture and soundtrack together. If the source audio is already wrong, extending it is how that wrong track gets seven more seconds. Fix or replace audio on the source before you buy the increment.

This is not a new Veo 3.1 generate

VEO 3.1 is the generate: category text-to-video, native audio, official 4K tier, 4 / 6 / 8 second clips, 40 credits. Qualities include 720p, 1080p, and 4K. That row invents a take from a prompt. It is allowed to restage. It is allowed to pick a new camera height. It is the wrong door when identity is already closed.

Same 40 credits. Different object.

• Generate: 4s, 6s, or 8s. 4K listed. Prompt in, new identity out.
• Extend: 7s only. 720p listed. Clip in, continuation out.

Flow users in particular confuse “I can keep generating in the Veo surface” with “I am extending.” Generating again rolls identity. Extending spends 40 credits to continue the identity you already approved. If you have not approved it, stop. Re-roll the source on the generator, then come back here.

Do not pick extend because the generate’s 4K disappointed you and you wanted “more movie.” More seconds at 720p is not a 4K restage. Do not pick generate because you wanted the clip to last past eight seconds. Past eight is this row, or a cut of keepers, not a prompt that asks Veo 3.1 for a length it does not list.

Spend on more seconds, not a new identity

A keeper is a clip whose last frame you would still ship if the video ended there. Extend is how you buy time past that frame. It is not how you:

• swap the talent
• restage the product
• change the lens language
• invent a second scene because the first one missed
• “fix” a melting pack by hoping the extra seven seconds drift into the shot you wanted

Those are a new generate on Veo 3.1, or a different family if Veo is the wrong physics. Continuation should read as finishing a sentence. Subject position, lighting, and camera height have to match the outgoing frame or the join will read as a cut even when the words in the prompt are correct.

Drift is not a feature of this row. The model continues from what is there. A product that is already melting will keep melting. A face that already slipped will keep slipping. You will have paid 40 credits for a longer miss, with native audio attached to the miss.

If you need a different idea, leave the extend category. If you need more time on a take that already holds, this is the row: 7s, 720p, audio on, image not required.

Inspect the last frame before you buy time

Open the last frame. If you would not freeze it as a still, do not extend it.

Common failure: the generate is almost right, so you extend hoping the extra seven seconds will wander into the shot you wanted. Almost-right is still not a keeper. Re-roll the source. Then extend.

If you need a longer finished piece, chain another 7-second extend after you have inspected the new last frame, or cut the keepers together. Asking this SKU for 10s or 15s is how you waste the 40 credits. The catalog exposes 7s only.

If 720p is too soft for delivery, that is a finishing problem after a continuation that actually holds — upscale or recut. It is not a reason to skip the keeper test, and it is not a reason to call a new 4K generate an “extend.”

Order: approve the last frame; write the next seven-second beat; run VEO 3.1 Extend Video at 40 credits with native audio; inspect the new last frame before you buy another hop. Reverse that order and you will pay generate rates to discover you wanted time, or extend rates to discover you wanted a different take.

FAQ

Can I request 10s or 15s on this row?

Not on the listed durations. The catalog exposes 7s only. If you need a longer finished piece, chain another 7-second extend after you have inspected the new last frame, or cut the keepers together. Asking this SKU for a length it does not list is how you waste the 40 credits.

Does extend include native audio?

Yes. The record sets audio: true. You are continuing picture and soundtrack together. If the source audio is already wrong, extending it is how that wrong track gets seven more seconds. Fix or replace audio on the source before you buy the increment.

Is this the same as generating another Veo 3.1 clip?

No. VEO 3.1 invents a take: 4 / 6 / 8 seconds, 4K, 40 credits. This row continues a take: 7 seconds, 720p, 40 credits, native audio. Use the generator when identity is still open. Use extend when identity is closed and you only need time.

What if 720p is too soft for delivery?

Then this is the wrong finishing step, not a reason to skip the keeper test. The listed max is 720p. Upscale or recut after you have a continuation that actually holds. Do not pick a different idea and call it an extend because the resolution disappointed you.
