How long a generated shot with speech can run
Eight entries publish a length. Two give a menu of fixed shot lengths, two give a range to choose from, two give a ceiling in minutes, one caps the file rather than the shot, and one publishes a free allowance. The rest say nothing. As of 2026-09-12.
| Model | What is documented | Detail |
|---|---|---|
| D-ID | Five minutes for a clip, ten for a talk | Supplied audio, not the script |
| Hedra | A maximum duration of ten minutes | And the take normally decides the length |
| MiniMax | Four to fifteen seconds | Per generation |
| PixVerse | Sixty seconds, and a hundred megabytes | Audio and video alike |
| Sora 2 | Sixteen or twenty seconds, to a total of 120 | Extensions add twenty at a time |
| sync-3 | Fifteen seconds on a free account | Paid limits follow the plan |
| Veo | Four, six or eight seconds | A fixed menu rather than a range |
| Wan 3.0 | Two to thirty seconds | Per generation |
Inclusion rule. Entries whose documentation states a duration for a generation, its audio, or the allowance a plan includes. A duration mentioned in marketing material without appearing in the documentation read for this register does not earn a row. Order. Alphabetical by model name.
1A menu, a range and a ceiling are three different constraints
A fixed menu of four, six or eight seconds forces a scene to be written in those units. A range of two to thirty leaves the decision to a writer. A ceiling of ten minutes is not really a constraint at all for drama, because nothing holds a single generated shot that long.
Reading them as one number misses the difference. The menu is the one that reaches a script: dialogue written in eight-second beats survives the model, and dialogue written to a thirty-second paragraph has to be cut before it can be generated.
2The longest published figures belong to talking heads
Ten minutes of avatar video and ten minutes of supplied audio are the largest numbers here, and they come from products aimed at presentations rather than drama. A single unbroken take is exactly what a corporate video wants and exactly what a short drama never uses.
So the length column is not a ranking. A short ceiling on a generator that cuts every few seconds is a better fit for a series than a long one on a product that expects a single speaker facing the camera.
3Extensions turn a ceiling into a sequence of joins
One entry reaches two minutes by adding up to twenty seconds at a time. Each addition is a join, and a join is a place where a voice, a level or a room tone can shift. The published total is therefore the length of an assembly rather than of a take.
Treated as a budget for one beat rather than one scene, the same figure becomes useful. Treated as a promise of two continuous minutes it will disappoint, and nothing in the documentation says which reading is intended.
- Shot length a line has to fitGenerations run 16 or 20 seconds, and an extension adds up to 20 seconds at a time to a total of 120
- Length per callAudio and video are each capped at sixty seconds and one hundred megabytes
- Shot length set by the takeThe audio normally determines the video length, and omitting the duration follows the source audio
- Audio sourceA script is either text of up to forty thousand characters or an audio url, with audio limited to five minutes for clips and ten for talksa script read aloud or a file
- Length per call on the free tierA free account runs one generation a month with a fifteen-second ceiling, with paid limits following the plan
