Cross-family format translation: how SIGMA-RAW becomes GIF
The SIGMA-RAW source is interpreted as Sigma Foveon camera captures normally stored as X3F with layered-sensor data, then rebuilt for GIF as an indexed-color animation or still image capped at a 256-color palette. Renaming the file suffix alone could never accomplish that translation.
Interpreted input - Sigma Foveon camera captures normally stored as X3F with layered-sensor data. Required output - An indexed-color animation or still image capped at a 256-color palette.

Reading SIGMA-RAW correctly and satisfying what GIF expects
What can fail when SIGMA-RAW specialized file format is interpreted
Foveon development has distinct color and noise behavior that a generic raw description cannot predict.
What Graphics Interchange Format cannot safely promise
Gradients and photographic tones can band, semi-transparent pixels get reduced to on/off transparency, and frame timing is rounded to the nearest centisecond.
How the GIF writer handles this route
Video-to-GIF output is sampled at 12 frames per second, capped at 960 pixels wide, and contains no audio.
The delivery decision for this SIGMA-RAW to GIF route
Choose GIF when the next app explicitly accepts it and its short animations and simple graphics role fits the job better than SIGMA-RAW.
What changes between the SIGMA-RAW model and the GIF deliverable
- GIF supports alpha transparency that SIGMA-RAW never had, so any transparent areas in the result are newly created, not carried over from the source.
- GIF can hold a timed animation, but SIGMA-RAW has no frames to give it; expect a single still frame unless more source material is supplied.
- Treat SIGMA-RAW-specific metadata fields as optional in the GIF result until you have actually confirmed they survived.
Acceptance evidence for the converted GIF
Record the SIGMA-RAW evidence before conversion
Compare with Sigma's reference software and inspect color, detail, highlights, crop, and capture metadata.
Test the GIF file in its receiving workflow
Play the loop in full, watching for banding, transparency edges, frame disposal, and whether the loop seam is clean.
