In addition to Long GOP inter-frame compression, the α7S III supports internal intra-frame (All-Intra) recording0 for the first time in an α-model body, where each frame is recorded independently at a high bitrate of up to 600Mbps. This can be useful for certain types of shoots as it allows maximum flexibility in post-production editing.

An HLG (Hybrid Log-Gamma) HDR picture profile, complete with the wide-gamut BT.2020 colour space, can be used for direct HDR (HLG) playback on compatible TVs. The result is true-to-life imagery close to what the naked eye can see, with detailed shadows and highlights, less blackout and less whiteout, all without the need for colour grading. In particular, 10-bit recordings reproduce a level of fine gradation and detail for extraordinary realism.
 High flexibility to fine-tune images as desired (colour grading required)  Instant high-quality image (colour grading not required)
Relying on a new high-precision stabilisation unit, gyro sensors, and optimised image stabilisation algorithms, the camera's Optical SteadyShotTM Active Mode provides the precise degree of optical image compensation needed during movie shooting, even for 4K video0. With this unprecedented level of stabilisation it's possible to shoot with the camera only, taking advantage of the compact size and mobility of the α system.
