The Flash Band Compensation firmware upgrade compensates for the “flash band” effect experienced by most MOS-based imagers.* As these imagers utilize rolling shutter, which records images line by line   instead of simultaneously, as with global shutter technology, they tend to be susceptible to image variance when a light flashes during shooting. A light band (flash band) can appear in the continuous two   frames when a flash occurs, similar to that from a still camera or strobe light. 
The free firmware upgrade enables the camera to use a newly developed LSI signal process that removes the flash artifact. It detects the “flash band” frame and combines it with the previous unaffected frame image to compensate devided flash band frames and maintain the natural frame sequence. 
The Flash Band Compensation firmware upgrade for the HPX301E will be available on the download section of the Panasonic Broadcast website, , starting in this summer. 
About the HPX301E 
The AG-HPX301E provides the ultimate quality and flexibility in an affordable, full-size HD shoulder-mount. Incorporating an innovative, low profile shoulder mounted design, the HPX301E P2 HD camcorder offers independent frame AVC-Intra recording, variable frame rates and the flexibility of interchangeable lens. The two-slot camera records stunning images in a variety of formats from master quality AVC-Intra and production quality DVCPRO HD to standard definition DVCPRO50, DVCPRO and DV. Features such as selectable gamma, Chromatic Aberration Compensation (CAC) and Dynamic Range Stretch (DRS) ensure optimum performance in a wide range of applications. 

With the introduction of the P2 ‘E’ card reducing the cost of P2 media from 32GB = £333 (was £1000) this camera will become hot property. I know a few cameramen who were interested in the 301 but the outrageous price of the P2 cards were real turn offs. This in my opinion will put Panasonic firmly in the driving seat and I hope to be one of the 1st to review the HPX-301 with a new ‘E’ card.   


Having been working in the video business since 1988 I have amassed a great amount of knowledge of both the kit and production values over the last 30 years.
