Re: HD vs HD-SR (What is the difference?)

Bob,

The SR is not a fully uncompressed solution, it adds a level of compression.

Tasha,

You can't make a comparison of HD to the SR. HD is set of formats such as 1920x1080 and 1280x720, the SR is a device that records many formats.

You can use any number of devices and solutions to capture HD, which I think is really what your asking for a comparison of. Some of these apply a slight level of compression and some none at all. Decks will apply compression (although the SR is damn good).

Devices/systems/Apps such as Rave (ours), FCP, Premier, and many others can capture in both compressed and uncompressed (fully uncompressed) formats.

Which is better. Well that is the debate of the century. Depends on what the end product will be, how big it will be and how much VFX will be done along the way. Feature films tend to like it uncompressed as much thru the workflow as they can get, where reality starts with a compressed format (but then again there isn't much VFX in reality).

To a trained eye, they can spot the difference between images with compression and ones without. The difference between uncompressed HD and HD on the SR again, is pretty damn good and many a film is shot using the SR but there are some that swear by uncompressed. An easy way to do a comparison is to get a capture (direct from a camera) into an uncompressed source, print or make a copy to SR and compare the two. You can even re-capture the SR copy back in (as uncompressed) so you have both sources on the computer, Then loop away and see if you can tell.

A comment we heard once after capturing in a tape from the SR to make a comparison was......"it looks just like the SR"....duh!

*Just make sure you are capturing in the same format for both as both ways(devices) will provide a slew of options and formats.


Hope that helps you out a bit.

Cheers,
Ramona
