Andy Thompson Posted September 28, 2011 Share Posted September 28, 2011 Hi I am shooting some B-roll of a sport event for a commercial on friday night. We will be using the EPIC at 2K, shooting 300fps or maybe 240fps (so we can lower compression). I have read somethings about the 2K being chunky in the blacks with noise. Has anyone experienced this? Will be shooting with the optiomo 24-290 to give myself a fighting chance under stadium lighting. Cheers Andy Link to comment Share on other sites More sharing options...

Cheers Andy From the tests I have done 2K from Epic is better than 2K from Red one, compression did not seem an obvious issue. Link to comment Share on other sites More sharing options...

Premium Member Stephen Williams Posted September 29, 2011 Premium Member Share Posted September 29, 2011 Was that at High Speed Stephen. 300 fps, there would be no point to shoot 2k unless high speed is needed. Link to comment Share on other sites More sharing options...
Andy Thompson Posted September 29, 2011 Author Share Posted September 29, 2011 I don't agree with that statement, but thanks for the clarification. Some shows here use 2K to get extra focal length from their lens, for instance. Link to comment Share on other sites More sharing options...

David McDonald Posted October 17, 2011 Share Posted October 17, 2011 Seems a really bizarre thing to do, there is a resolution hit at 2k. A x2 tele-converter would be a better option. I did a couple of tests at 2K 300 FPS....and I did notice some pretty bad noise in some areas, mostly the blacks. Oddly, with one test shot of someone in extreme sunlight, the image was disgustingly noisy...like it looked like a low quality H264 compression.... And that shot was at 48 fps at 5K....we couldn't really figure out why...the compression rate must have been unusually high for that one shot.

Dustin Lindgren Posted October 18, 2011 Share Posted October 18, 2011 (edited) Seems a really bizarre thing to do, there is a resolution hit at 2k. A x2 tele-converter would be a better option. I could see how its bizarre if your in a controlled environment. Although in some outdoor situations its awesome. The other day i had a Red 300 and a doubler in my pack. At 4K the 300 wasn't enough to put my subject into in full frame. I switched it over to 2K (600) and it still wasn't enough. Then I put on the doubler at 2K (1200) and the subject was in full frame. You start to loose stops but if your shooting in daylight it doesn't matter. Great way to get crazy Focal DOF on anything as well. Lots of stuff to work with if you have a doubler and the capability of switching from 4 to 2K! It just depends on what you shoot for a living...

Premium Member Marque DeWinter Posted November 4, 2011 Premium Member Share Posted November 4, 2011 The compression at 2k isn't nearly as bad as on the Red One, but its going to depend on how much light you have. If after compensating you end up rating at around a T1.2 @300fps in 2k 800 ISO you're going to have problems. But if you end up at a T5.6 you should be ok without too much difference in quality. ~Marque Want To Shoot A Scarlet... http://www.indiegogo.com/Red-Scarlet-Project?a=32535&i=addr Link to comment Share on other sites More sharing options...
