rkg Posted March 26, 2017 Report Posted March 26, 2017 Hey guys, This year I decided it might be good to bring along a decent sized monitor to the Chicago show in order to show some of my work. It gave me an opportunity to play around some with how to display images/pieces. I had been thinking for a while that some kind of "panning" image would be a cool way to show off sword details, but gave up on using video for this a while back as motion blur obliterates the fine details. The video below is panned though a fixed image. The interesting thing is that the more resolution/stuff you can see, the slower you have to pan to keep the "motion blur" (which it isn't in this case - I think it has to do with the monitor's refresh rate/pixel size) so it isn't objectionable when viewed full size (its 1080). you can hit the space bar while its running and see the "actual" resolution - it "jumps" into sharpness when stopped). I also found I had to use the tool's "extreme resolution" to get it to look this good = huge files, but hey... Whaddya think? http://www.rkgphotos.com/facebook_stuff/osoraku_test.mp4 Best, rkg (Richard George) 2 Quote
BIG Posted March 27, 2017 Report Posted March 27, 2017 Great, is it makeable to fix two films together for one oshigata film from boshi to nakago seeing both sides of the sword? Best Regards Quote
Greg F Posted March 27, 2017 Report Posted March 27, 2017 Well done Richard, I like it a lot. Greg Quote
Ken-Hawaii Posted March 27, 2017 Report Posted March 27, 2017 Yes, Richard, very effective. You're right that the monitor's refresh rate is the limiting factor, which is also dependent on the amount of RAM on the video card. I assume that you used a slider to move the camera over the blade; did it have a constant-speed linear motor to control the movement? If so, which brand/model do you have? Recording at FHD (1920 X 1080) doesn't really give you "huge" file sizes - they're 4X bigger at 4K resolution! Thanks!Ken Quote
rkg Posted March 27, 2017 Author Report Posted March 27, 2017 Ken, Thanks for the comments. I have various sliders/rails, etc, but they weren't used in this case - this was a digital pan through a single image that was what, about 8200 pixels wide... In the past I have done a bunch of testing trying to get all the possible detail to show up in a video when physically doing a slide of a camera across a blade, but I could never get it to work very well (no doubt a combination of things - codec/compression issues, motion blur, stray vibrations,, etc - the image was sharp as it could be when still, but when motion began, yuk...) - I think you probably would need a rail you could micro-step, take stills, and combine those in post into video to get that to work, but this is better for me - you just need a painfully high resolution image to begin with (and that I can do...). Agreed on the size - 4K video is big - I guess I should have clarified that I was talking about was the resulting video from the tool - at its highest (least compressed) output resolution, the files were 10X or more larger, and... Best, rkg (Richard George) Quote
rkg Posted March 27, 2017 Author Report Posted March 27, 2017 Yeah, that's easy enough to do if you have the images... Best, rkg Great, is it makeable to fix two films together for one oshigata film from boshi to nakago seeing both sides of the sword?Best Regards Quote
Ken-Hawaii Posted March 27, 2017 Report Posted March 27, 2017 Glad you clued me in, Richard, because I was ready to set up my own slider system with a 4K camera & a macro lens. Didn't think about vibration, & a pair of tripods probably wouldn't eliminate everything. I could probably reduce most motion blur by shooting at 60 fps...not sure that even my computer system could handle 120.... One nice thing about owning a computer consulting company is that I get a lot of free commercial software, including Sorenson Squeeze & Telestream Episode, so compressing & transcoding video is a no-brainer. I'm just starting to play with h.265, but that might eliminate some of the "fuzz." Yeah, there are a lot of variables that might make the whole effort too much of a hassle. Ken Quote
kissakai Posted March 27, 2017 Report Posted March 27, 2017 The video looks really good to me Although you can stop/start the video I would pan slower to allow the viewer to take in the details better Quote
SwordGuyJoe Posted March 27, 2017 Report Posted March 27, 2017 I'm sure I won't be the only one inquiring about the costs of your services in Chicago. Looks great! Quote
Hoshi Posted March 28, 2017 Report Posted March 28, 2017 Beautiful. Have you considered adding a dynamic pan/tilt with lighting at the end of the video to bring out some of the details of the steel structure/hamon? Quote
