How long can a Bonega AI video be?
A finished video has no maximum length, and no plan imposes one — your credit balance is the limit, at 4.125 credits per second. What is capped is a single REQUEST. The generation form's slider runs from 5 to 120 seconds in 5-second steps and is labelled "120s max"; the API behind it accepts up to 650 seconds per request, flat, on every plan. Past that you EXTEND a finished video: each extension appends up to another 120 seconds and nothing caps the running total. Internally a request over 15 seconds is generated as several segments and merged into one MP4.
What a balance buys, in seconds
- 21 credits — a 5-second clip, the shortest the slider allows.
- 62 credits — a 15-second clip, the longest single segment.
- 200 credits (Standard, $9/month) — 48 seconds.
- 1500 credits (Pro, $49/month) — 6 min 3 s.
How a long video is actually built
Requests longer than 15 seconds are split by the segmenter and generated in order. Segment one is generated from your prompt or your image; every later segment animates the last frame of the previous one, which is what keeps the subject and the setting continuous across the join. The finished segments are merged server-side and you download a single file.
A 30-second request is generated as 15 + 15 seconds. A 40-second request is 15 + 15 + 10. A 120-second request, the longest the form allows, is 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15.
Going past one generation
Past 120 seconds you extend rather than request more: open a finished video, choose to extend it, and the new seconds are generated from its last frame and appended. The seconds you already have are not re-generated and not re-billed, so a longer piece costs the same per second however many extensions it took. There is no ceiling on how many times a video can be extended and no cap on the total length that results — the running total is not compared against any maximum, so what stops you is your credit balance.
Longer is also not automatically better. Each additional segment is one more join where the subject can drift, so a long result is usually built as several deliberate shots rather than one continuous take. The cost is linear in seconds, not in segments, so splitting a plan into shorter takes costs you nothing.
Frequently Asked Questions
Is there a maximum video length?
Not for a finished video: nothing caps the total, and no plan imposes a length limit, so the ceiling is your credit balance at 4.125 credits per second. One REQUEST is capped — at 120 seconds on the generation form, and at 650 seconds in the API that validates it, identically on Standard and on Pro. Extending a finished video appends up to another 120 seconds each time.
Why is my long video generated in pieces?
The pipeline generates at most 15 seconds per segment and merges them into one MP4. You receive a single file; the segmentation is only visible in how long the generation takes.
