hijodeibn Posted February 17, 2017 Share Posted February 17, 2017 Just can`t believe it, C100 has been in the field for years, and nobody ever raised his voice to said anything about ghosting in this camera, just made some tests and you can see some pics attached….. Am I seeing what I think I am seeing?, is it ghosting?, @kidzrevil I think your expertise is needed here! Quote Link to comment Share on other sites More sharing options...

fuzzynormal Posted February 17, 2017 Share Posted February 17, 2017 Hey, my camera does that too! Actually, all the cameras I've used over the years have done that. Quote Link to comment Share on other sites More sharing options...

Justin Bacle Posted February 17, 2017 Share Posted February 17, 2017 Looks more like compression artifacts to me. Where you recording internally or externally ? It wouldn't surprise me if this happened using the internal recording as the bitrate is not that high. Quote Link to comment Share on other sites More sharing options...
hyalinejim Posted February 17, 2017 Share Posted February 17, 2017 That's normal motion blur. Quote Link to comment Share on other sites More sharing options...

It looks like motion blur. OP: Shoot the exact same shots and use a tripod. Don't move the camera. Upload those images. If the "ghosting" is there, you can start worrying.

This is internal recording, but I also recorded externally with a Ninja Star, I see something similar in that footage... Quote Link to comment Share on other sites More sharing options...

Compression artifacts are blocky distortions, chroma banding, things like that. This isn't that. I'm going to wager these stills are captured from video clips where the camera was in the middle of a violent handheld pan. Most likely you're recording @24fps, right? In other words: a normal visual result. We're looking at a still that represents 1/48th of a second as the lens moves quickly. 2 minutes ago, hijodeibn said: really looked like ghosting Was the camera moving for these stills or not?

Yes, 24fps, but the last picture that I attached from the Ninja Start worries me a lot, check the base of the flowerpot, that artifact doesn`t look like motion blur... 4 minutes ago, fuzzynormal said: Compression artifacts are blocky distortions, chroma banding, things like that.

(how a beginner has access to c100 and a Nija Star recorind system is interesting, but perhaps it's a student) Don't know what's really up until certain questions are answered. From what I know about c100 ghosting, it's a field interpolation error that pops up from time to time within the hardware of the camera. It looks a little like inverted field rendering that one would see back in the NTSC days. 11 minutes ago, hijodeibn said: yes, it is moving, there is no other way to see the ghosting. Thanks for the info. My conclusion/guess is that you're not aware of the physics of light and how cameras work. That's fine. You'll learn. Bottom line: your camera is operating without error. You're making an incorrct assumption about your perfectly natural visual results. It's most likely not "ghosting" it's motion blur. The c100 "ghosting" would look more visually stratified. If I'm wrong, I wouldn't be absolutely surprised, but that's my best guess. Quote Link to comment Share on other sites More sharing options...
webrunner5 Posted February 17, 2017 Share Posted February 17, 2017 Could be a shutter speed problem, but that would be a damn extreme example of it from your information on the specs. Quote Link to comment Share on other sites More sharing options...

Well, we don't know how violently the lens was panning when those shots were taken. Looks well within normal motion blur probability to my eye. Why are we looking at stills anyway? The c100 is a video camera. The OP should upload the actual clip. webrunner5 1 Quote Link to comment Share on other sites More sharing options...

As they say, "There's no such thing as a dumb question..." Just because a question might betray someone's comprehension of things doesn't make the question in of itself ridiculous. After all, learning about this stuff now will lead to a better skill set down the line. Here's some 101 level info I found quickly using the world wide web information super highway search engine provided by google.com: http://www.red.com/learn/red-101/camera-panning-speed Justin Bacle 1 Quote Link to comment Share on other sites More sharing options...
hyalinejim Posted February 17, 2017 Share Posted February 17, 2017 @hijodeibn If you wanna check if the C100 has Xc10 style ghosting you need to crank up the ISO to check whether it's there or not. If it does, then you can start worrying about whether it's visible at base ISO or not. There's nothing would worry me in the samples you've posted and I'm a ghosting afficionado!
