The A9’s video features include video timelapse modes, capture of high-resolution still images during video recording, Electronic Image Stabilization (EIS), and burst capture of up to sixty 12-megapixel still images per second. Ultra-wide angle and small form factor lenses are supported with full lens distortion correction. The A9 also support High Dynamic Range (HDR) video.

Ambarella A9 Feature Summary:

  • 4K Ultra HD video recording @ 30 fps.
  • High definition video recording at 720p @ 240fps and 1080p @ 120fps.
  • Burst mode support for still image capture of over 700 Megapixels per second.
  • Multi-exposure High Dynamic Range (HDR) imaging support, including local tone mapping, preserves image details in high contrast scenes.
  • Electronic Image Stabilization (EIS) with rolling shutter correction.
  • 3D Motion-Compensated Temporal Filtering (MCTF) with de-ghosting for reduced artifacts and low light performance.
  • Support for applications including wireless preview, playback, and upload of stills and videos to a smartphone or directly to the Internet over WiFi.
  • Interfaces such as DDR3L, USB 2.0 host, HDMI, and SDXC SD card.
  • Low power – <1W for 1080p60 encode, <2W for Ultra HD 4K encode.
