HelixWorld makes 121 frames at 24 FPS: Sume rows that run longer
HelixWorld's preview caps a run at 121 frames, about 5 seconds at 24 FPS. Sume's video rows with sound run 5 to 15 seconds; here is the arithmetic and the rows.
HelixWorld's preview runs at most 121 frames, and at its 24 FPS that is 121 / 24 = 5.04 seconds of video per run. If your plan needs a 10-second shot with sound, the Sume rows minimax-h3 and minimax-h3-max list 5 to 15 seconds with native stereo audio, so one request covers it without stitching.
The HelixWorld numbers come from its GitHub page and the Sume numbers from the Video Router docs, both read 2026-10-14. HelixWorld itself is not on Sume; see the separate answer on availability.
How long is one HelixWorld run?
The repository says the system supports up to 121 frames in total, with segment durations set through an action sequence, at 768×512 and 24 FPS. Segments divide the 121 frames; they do not extend them.
| Frames | Seconds |
|---|---|
| 24 | 1.00 |
| 72 | 3.00 |
| 121 | 5.04 |
What do Sume rows give for length and sound?
The Video Router table lists these ranges and audio notes. A shot longer than 5 seconds fits in one request on all three rows below.
| Row | Duration | Audio |
|---|---|---|
| minimax-h3 | 5–15 s | native stereo |
| minimax-h3-max | 5–15 s | native stereo |
| gemini-omni-flash-1.1 | 3–10 s | native synced |
What stays different?
HelixWorld reacts to camera and keyboard input as it generates, and a Sume row does not: you describe the shot in the request and fetch the result from the job. Pick on length and sound, then confirm the row with GET /v1/video-router/models/{model_id}.
