Replay register, release CTR-1
For a single test, open any ID in the tables. To repeat the whole issue, download the complete CTR-1 pack. It includes the fifteen inputs, the three original films, source credits and the generator. Start with the enclosed manifest before regenerating files.
Every test input runs for four seconds at ten frames per second. The format is 640 × 360 H.264, with no audio track. Frame 0 starts at zero. An interval ending at frame 30 stops just before frame 30 appears. The JSON manifest gives every filename, SHA-256 digest, reference interval and edit. L01 · Reproduction script
Generated controls
The six controls use solid colors so a decoder, recorder or export can be checked against an exact frame. None contains a photograph of a person or vehicle.
| ID and replay | Inspect |
|---|---|
| C01 | Empty scene and fixed divider. All forty frames show the same composition. |
| C02 | The square's left edge reaches the divider at frame 24. |
| C03 | A stationary rectangle is present on frames 10 through 29. |
| C04 | Two seven-frame pulses. Frames 12 through 21 are clear. |
| C05 | Two rectangles partially overlap on frames 16 through 26. |
| C06 | Five gray frames interrupt the otherwise unchanged view. |
Camera recordings
The capture families are the individual source films, and the two cuts within a family are related observations. A scene landmark in the manifest marks a point to verify after ingest. Only F01 carries a separately inspected line-crossing instant.
| Replay | Source time | Inspect |
|---|---|---|
| F01 | 1–5 s | First gray sedan, approaching lane. Front bumper meets the line at frame 27. The virtual line runs across the left half at y=270. |
| F02 | 10–14 s | A light vehicle waits on the right of the roadworks. |
| F03 | 2–6 s | Oncoming lights on a Cologne street. The storefront anchors the left edge. |
| F04 | 9–13 s | A later view along the same street toward the queue. |
| F05 | 1–5 s | Albury timelapse. Find the lit intersection below center. |
| F06 | 8–12 s | Later traffic in the Albury view. The four seconds are playback time. |
F01 and F02 derive from 137a's Temporary traffic signal at Colonel By Drive. F05 and F06 derive from Thennicke's Dean Street timelapse Albury NSW. Both authors released their originals under CC0. Excerpts are trimmed, resized, resampled and encoded without sound. F01 · Signal source · F03 · Timelapse source · CC0
F03 and F04 derive from Maximilian Schönherr's Cars Passing by at Night. Both received the same format changes. These excerpts and the M03 adaptation are distributed under CC BY-SA 4.0. F02 · Cologne source · License
Altered field excerpts
Compare each pair in the same player. At 2.7 seconds the sedan reaches the reference line in F01. Open M02 at the same instant. The mask covers the contact point, so copying the parent annotation across would credit the reviewer with seeing through a black rectangle.
| Replay | Parent | Edit applied |
|---|---|---|
| M01 | F01 | Remove chroma for the full clip. |
| M02 | F01 | Cover the lower-left quadrant with black on frames 10 through 29. The cover intersects the reference line. |
| M03 | F04 | Carry frame 9 forward through frame 29, then resume at frame 30. |
All modified files retain their parent's source credit. The field clips were selected for replay and annotation practice. No clip supplies an estimate of performance at another site.
