Sony HDW-790P

This camera replaced the HDW-750P with enhanced features but still the super reliable tape based workflow.

HDCAM, introduced in 1997, was the first HD format available in Betacam form-factor, using an 8-bit DCT compressed 3:1:1 recording, in 1080i-compatible downsampled resolution of 1440×1080, and adding 24p and 23.976 PsF modes to later models.

The HDCAM codec uses non-square pixels and as such the recorded 1440×1080 content is upsampled to 1920×1080 on playback. The recorded video bitrate is 144 Mbit/s. There are four channels of AES/EBU 20-bit/48 kHz digital audio.

The HDW-750P makes it easier than ever to capture pictures that will satisfy the most exacting producer. By shooting 25 frames per second in progressive scan mode (25P), your shots will share “filmic” motion portrayal that can add a subjective richness to improve both the quality and marketability of your production. And new for 2005/6 is a new version of camcorder software: Version 2. This boosts the latitude of the camcorder to give an even more film-like image, allowing more detail to be seen in the highlight and lowlight areas of the picture.

It is used for some of Sony’s cinema-targeted CineAlta range of products (other CineAlta devices use flash storage).
