Hi, Could you post an image? 2k Bayer is fairly soft the SI looks the same as the RED @ 2K IMHO. Stephen Link to comment Share on other sites More sharing options...
Premium Member Adrian Sierkowski Posted September 28, 2008 Premium Member Share Posted September 28, 2008 IIRC, due to the bayer pattern, it wouldn't really resolve 2K, more like 1.5K give or take? Might be the issue? Talking out my ass a bit on that, but perhaps scaling down to 1080p would "sharpen" it's looks a tad. Link to comment Share on other sites More sharing options...
Brian Drysdale Posted September 28, 2008 Share Posted September 28, 2008 Any SI 2K frame grabs I've seen tend to to have a "16mm" quality about them, but I wouldn't call them soft, more lower resolution compared to the RED 4k frames I've seen. It won't have edge enhancement, so it'll have softer look compared to video. Link to comment Share on other sites More sharing options...
Mike Simpson Posted September 29, 2008 Share Posted September 29, 2008 Could be that lens too, or a combination. Have you shot with any primes? Link to comment Share on other sites More sharing options...
Rohan Dadswell Posted September 29, 2008 Share Posted September 29, 2008 Make sure that the lens is colomated to the SI-2K. When I first got mine I borrowed a few lenses off a mates Aaton and they all looked a bit soft. Turns out that while both the camera's mounts were within specs they were slightly different and this caused some softness. I think with a zoom this would be even more of a problem. Yes, the SI-2K does not have the 'video sharpness' of other HD cameras but you can always dial in detail sharpness in post if you like that look - but that wont help if the lens is soft. Are you judging the soft look on the camera monitor/viewfinder or in post at full rez? Link to comment Share on other sites More sharing options...
Rohan Dadswell Posted September 29, 2008 Share Posted September 29, 2008 Also make sure that you are shooting at quality 3 or 4. Q1 & 2 will be softer. Link to comment Share on other sites More sharing options...
Jason Rodriguez Posted October 17, 2008 Share Posted October 17, 2008 Also make sure you are not using the DPX, JPEG, or BMP from the "SAVE IMAGE" frame-grabs. Only use the DNG for resolution tests. The others do not have a great debayer algorithm, and so they will appear soft. Link to comment Share on other sites More sharing options...
Michael Maier Posted October 17, 2008 Share Posted October 17, 2008 (edited) I think this is just a characteristic of the SI2K. After all it's a 2K camera which in 16:9 is not that much different from 1080. When you throw the Bayer in, it gets even closer if not lower. From what I have seen from the SI2K it's not sharper than the Sony EX1 or EX3. I would actually say it may be softer than these cameras. Having said that, if it is really soft, like almost SD soft, it may be the lens. If you are using and old C mount 16m lens you probably won't get all the sharpness the camera can produce.

Jason Rodriguez Posted October 18, 2008 Share Posted October 18, 2008 Keep in mind the Sony cameras have in-camera sharpening, where-as we do not (this would be counter-productive to sharpen RAW, even during the RAW decode, since sharpening is irreversible). If you want to reduplicate that in-camera sharpening effect, you will have to sharpen in post. From my experience with cameras like the F900, HDC-1500, etc., a similar "softness" can be achieved with the Sony cameras that allow you to turn the sharpness all the way off.

DS Williams Posted January 26, 2009 Share Posted January 26, 2009 The SI 2k looks a but to me like a glorified hpx500 or hdx900...it has a panny look. But, I saw Slumdog in theaters and the camera not only looked soft, it looked extremely noisy as well. Noisy in shadows and midtones, I even saw pixels firing to white and back. It was strange.
