Die Wahl des Sensor-Modus beeinflusst Auflösung, Crop, Rolling Shutter und Empfindlichkeit. Ich wähle den Modus basierend auf der benötigten Bildrate, dem gewünschten Look und den Optik-Anforderungen.
Camera configuration that determines how the image sensor captures and processes data – includes options for resolution, aspect ratio, crop factor, frame rate, and sensor area utilized, affecting image quality, field of view, and recording format for different shooting requirements.
What is a Sensor Mode?
A Sensor Mode refers to the configuration of the image sensor readout in digital cameras. It determines which part of the sensor is used, at what resolution recording occurs, and how the data is processed.
Basic Principle
| Aspect | Description |
|---|---|
| Definition | Sensor Configuration |
| Influences | Resolution, Crop, FPS |
| Camera-Dependent | Varies by model |
| Setting | Before shooting |
Typical Parameters
| Parameter | Options |
|---|---|
| Resolution | 2K, 4K, 6K, 8K |
| Aspect Ratio | 16:9, 2.39:1, Open Gate |
| Sensor Area | Full, Crop, Windowed |
| Frame Rate | 24, 25, 30, 60+ fps |
Full Frame vs. Crop
| Mode | Characteristics |
|---|---|
| Full Sensor | Maximum area |
| Super 35 Crop | S35 equivalent |
| APS-C Crop | Tighter crop |
| Windowed | Variable |
Resolution Modes
| Resolution | Typical Use |
|---|---|
| 2K | Standard, fast |
| 4K | Master format |
| 6K | Reframe option |
| 8K | Future-proof |
ARRI Sensor Modes (Example)
| Mode | Description |
|---|---|
| Open Gate | Full sensor |
| LF 2.39:1 | Scope crop |
| 4K 16:9 | Standard |
| S35 | Super 35 Mode |
RED Sensor Modes (Example)
| Mode | Description |
|---|---|
| 8K FF | Full Frame 8K |
| 6K S35 | Super 35 |
| 5K WS | Widescreen |
| 4K 2.4:1 | Anamorphic |
Readout Methods
| Method | Characteristics |
|---|---|
| Full Readout | All pixels |
| Binning | Pixels combined |
| Line Skip | Lines skipped |
| Windowed | Cropped section |
Binning
| Aspect | Description |
|---|---|
| 2x2 Binning | 4 pixels → 1 |
| Advantage | Increased sensitivity |
| Disadvantage | Reduced resolution |
| Application | Low-light, HFR |
High Frame Rate Modes
| FPS | Typical Mode |
|---|---|
| 24-30 | Full Resolution |
| 60 | Often cropped |
| 120+ | Significant crop |
| 240+ | Heavy crop |
Rolling Shutter
| Mode | Effect |
|---|---|
| Full Readout | More rolling shutter |
| Crop | Less RS |
| Global Shutter | No RS |
| Line Skipping | Varies |
Aspect Ratio Modes
| Ratio | Sensor Usage |
|---|---|
| Open Gate | Maximum |
| 16:9 | Standard HD/UHD |
| 2.39:1 | Scope crop |
| 4:3 | Anamorphic friendly |
Impact on Optics
| Mode | Effect |
|---|---|
| Full Frame | Wider FOV |
| Crop | Telephoto effect |
| Combo | Same lens = different FOV |
| Planning | Lens choice |
Data Rate
| Mode | Data Rate |
|---|---|
| 4K 24fps | Baseline |
| 6K 24fps | ~2x baseline |
| 4K 120fps | ~5x baseline |
| 8K 24fps | ~4x baseline |
Storage Considerations
| Factor | Influence |
|---|---|
| Resolution | Directly proportional |
| Frame Rate | Directly proportional |
| Codec | Compression |
| Bit Depth | More = larger |
Workflow Implications
| Aspect | Consideration |
|---|---|
| Post-Performance | Higher res = slower |
| Proxies | For high resolutions |
| Reframe | With oversampling |
| VFX | Resolution requirements |
Best Practices
| Practice | Reason |
|---|---|
| Match to Delivery | Don't overdo it |
| Consider Storage | Budget |
| Test First | Check on set |

Today
Sensor modes are a critical aspect of modern digital cinematography. The balance between resolution, frame rate, crop factor, and data rate requires careful consideration. With the evolution towards larger sensors and higher resolutions, choosing the right mode is increasingly important for workflow and creative outcomes.

Perspectives
Director
Sensor-Modi bestimmen das visuelle Potenzial meiner Aufnahmen. Höhere Auflösungen geben mehr Flexibilität in der Post, während bestimmte Modi spezielle Looks ermöglichen.
Producer
Sensor-Modi beeinflussen Datenmenge und Speicherbedarf. Höhere Auflösungen und Framerates erhöhen die Kosten für Medien und Postproduktion erheblich.
