Thanks Dylan,

What version of QT do you have installed in the WIN64 computer?

Thanks,
Paul

Thanks Dylan,

When you mentioned “codec support” and “driver support,” do you mean software related to BlackMagic/AJA capture cards or do you mean Apple QuickTime related support?

Thanks,
Paul

Hi Tom,

The electrical power in the UK is 220V 50Hz. So your light will need a lamp that works with 220V 50Hz.

You’ll also need to stop by a local hardware store to get the right type of electrical plug.

Regards,
Paul

Some people have had a better experience with PPCS3 if they have at least 2 gigs of RAM for every processor core.

In a “consumer” 32-bit MicroSoft OS, this can not be had, but with certain “other” versions it can, for example: WIN Server 2003 32-Bit with PAE enabled, WIN Server 2003 64-Bit, WIN XP 64-bit, WIN Vista 64-bit.

Others have had great success if the BIOS is updated to work correcty with 4-core processors. (Check out http://www.biosman.com to know how to update your BIOS without messing up your SuperMicro motherboard.)

Others have had great success if the temperature inside the case is within designated extremes. If you realize that inside the case the temperature gets to 140º Fahrenheit too often, that may be the cause of your machine slowing down. By design, Xeon Intel processor chips cause themselves and the RAM to slow down if the temperature inside the case gets too hot.

Finally, others have had great success by being careful with their power supply.

If your power supply cannot handle the power requirements (the wattage) of all the stuff connected to it, you may notice strangeness. If the computer at times turns itself off for no reason, (no WIN XP exit, just turns off…) the power supply is being over taxed in wattage.

This can also happen if you connect too many high wattage components to only one or two rails (electrical circuit coming out of the power supply.)

For example, if the power supply has four rails (4 circuits) and each can handle 250 watts (the power supply is rated 1000 watts on its chassis), and you just happen to install 300 watts of stuff on only one of the rails, the power supply will then turn itself off when the heat goes up. In this case, the power supply is rated to 1000 watts, but 300 watts causes it to fail because of the overload of one of the circuits.

You may also want to check your power supply just to make sure it’s completely compatible with your motherboard. Most of the motherboards labeled somewhere as being 5000x… (meaning they are compatible with XEON 5000 sequence processors) also, expect a power supply that is EPS12V compatible.

When you shop online for a power supply, type “EPS12V” in the site’s search engine. This may help you determine quickly if they have power supplies that work with your motherboard.

Based on what you have explained, I would first look at your BIOS and check if it’s compatible with the processors installed.

Regards,
Paul

Dear John and Steve,

[Paul Thurston]

When you telecine/transfer a 35mm film to video and the result is for NTSC frame rate, it gets transfered at 23.976 fps (23.98 fps).

It also is captured as RGB 4:4:4 and not Y, R-Y, B-Y (YUV) 4:2:2.

The difference between 4:4:4 and 4:2:2 makes a difference for motion representation and color. This difference in capture color space is what many point out as a strange difference between telecined 23.98fps and camcorder captured 23.98fps video.

What randy Strome saw, has been noticed since 2000. In fact, I read that the first person in SONY America to point it out publicly was fired. Not that it was a secret, by any means, but it was an issue that only engineers could point out and that most if not all viewers (non engineers) wouldn’t notice or care about.

NOW…

An interlaced HD video transfered to film and the result seen on a movie theater demonstrates the opposite. It looked like interlace HD video (movement and color space.) It did not look like film captured images.

On the other hand…

I have seen the last Star Wars episodes on film and on TV. They both look like film-captured images. The difference is that the HD data was in fact 4:4:4 captured and never went to 4:2:2 color space until broadcast masters where made.

You would probably not guess that color space could affect the representation of movement, but it does.

Now you can understand why the Sony F-23 4:4:4 camera head is so expensive (RGB 4:4:4 capture, F-11 at 2000 Lux, 98% reflectance.)

Please note that regular HD cameras and for that matter SD cameras that capture at 23.98 also portray movement correctly as film captured images would. The limitation here again is the difference between native all the way 4:4:4 color and native 4:2:2 color. You could say that interlace stuff definitely does not look at all times like film, when shot at 24fps/23.98fps, but the same is true of all 4:2:2 video (in the eye of a video engineer.)

Does this mean that 4:2:2 images captured with an HD camcorder should not be used for filmout or TV? The answer is: they should be used. Since the only people who will ever notice the difference between motion portrayal in 4:4:4 and 4:2:2 color space will probably only be… a video engineer.
