FAQ:

1.What is DNG and RAW format?

RAW format is a format of single sensor cameras (photo or video) with Bayer mosaic on sensor: with RG,BG pixel sequence, this format records in DNG - Digital Negative file format. It looks like negative film in photography industry. There's more information about RAW and DNG available on ADOBE's site:

2. Why use RAW?

FIRST, offline decoding of RAW using ADOBE AFTER EFFECT software

has far better quality then any hardware conversions applied inside the camera;

SECOND, memory use is half of what you would need for recording in YUV file format; yet, DNG can be easily converted to YUV or RGB using Adobe software.

Thus, a less expensive Flash recorder can be used for recording the same amount of high quality video.

3. What can you see on the control monitor?

You'll see a high quality color preview of what you are recording. A preview will not be as good as after using Adobe's conversion but you can already see some of the presets and corrections for different CC, gamma, WB . Obviously, post production brings the quality to a completely new level. . Note that you can see traditional viewfinder B/W picture, if you want to, by turning off color conversion.

4. What about 4:4:4 (RGB) output?

With our base camera you may convert materials from RAW to RGB (4:4:4) on external PC, and you don't need to have an additional converter on the camera. Still, it is possible

to do this as an option for some applications, such as live broadcasting and work with third party hardware with 4:4:4 support. For best possible quality it may require the use of an additional debayering processor with 4:4:4 output.

5. Does your camera support traditional accessories?

Yes, of course: Matt boxes, supports, power suppliers, lenses can be used. Custom adapters and custom lens mounts can be used as well.

As for the viewfinder, it is possible to use a standard/third-party one, but for better results with focusing we recommend using our high quality LCD monitor. Our monitor has far greater resolution (1024x768) then any of the possible viewfinders, so more small details will be visible in the picture.for better focusing we have special zoom function in all small monitors, when you may see pixel to pixel picture on lcd screen

However, if you want to use a traditional viewfinder,it's not a problem: almost all models can be connected as special order. (some additional fees apply)

6. How does your camera compare to with 3sensor cameras and single CMOS cameras?

What is better?

Of course, 3 chip color cameras may offer more in terms of picture quality, but modern CMOS sensors and Adobe software make the actual difference rather small. For a way to approach the comparison, take a look at digital photo cameras: all of them are single sensors and quality is fine. If you use offline debayering software quality actually will be same.

7. T-stop, F-stop, bits, and so on... What is different from film and other cameras?

T-stop is how much light (in lum) between max light and min light is visible in same picture. In digital cameras this parameter depends on presets, and may be variable, as well as with linear or with gamma correction. If we have more bits, we may have less problems of shooting on post production, because we have more information in picture. However, the additional information must be recorded on your storage:for 10 bit it will be 20 % more then for 8 bit, and for 14- it will be 80% more and correspondingly more expensive, as well. In the end, the fact is that if you want to have a good picture, you can get it on a 14- bit camera and on a 10- bit camera, any you need: just use correct presets, and all viewers will be satisfied with the picture on the 8-10 bit LCD. If you compare our cameras with others- it will have the same picture when using correct presets. As for the film cameras - you'll have more flexibility with film cameras on post production, but with digital cameras you have more flexibility while shooting, where you may test your picture any time you need. If the picture seems to be lacking, with lower light or bad T-stops, you may re-shoot it immediately with different presets.

9. We are using Canon XL-H1, will your Flash Recorder work with it and how is it controlled.

Yes, our FDVR works with any HDSDI compatible devices, cameras, computers and so on. You may control it from buttons on recorder, USB/RS232, using control software for Windows, and from some Pocket PC using RS232.

Also, if you want to have some custom configuration or specific control option (Sony 9pin etc.) it can be done as a special order (some additional fees and a certain time delay apply)
