what the heck

[Colin Hubick]

check out this 3 legged horse. very strange artifacts around the legs of the horse and the calf. Anybody seen this before? This was shot with build 17 final, and was shot to 8gb RED Brand CF cards. This appears in the RAW files, so I don't think it's a product of the processing (which was done through REDLINE).

Is this something that is resolved in build 18? Which brings me to a final release of build 18. Can we expect anything soon?

Looks like it could be a severe rolling shutter artifact to me, though I don't know if a horse's leg could move fast enough to make a leg disappear.

A still frame of something with a lot of motion blur is hard to interpret. Does it look Ok when played at speed?

I would say it is motion blur combined with rolling shutter (the horse's leg had moved from a not-yet-scanned part of the frame to an already-scanned one.)

This just looks like motion blur to me.

Motion blur. Totally normal. If this was a problem for any reason (like wanting production stills from the footage, or if your name is Tony Scott), then the shutter needs to be faster.

I found a frame from 35mm footage we shot this summer that exhibits a similar form of artifacting around the guys right arm.

 

[Simon Valderrama]

it's the addictive mixing of the foreground and background motion blurs, both having different speed and direction. some details of the backround seem to pass through the foreground motion blur because they're alot brighter ... that's why it's difficult to replicate this kind of effect in 2d compositing if you're working 8 or 16 bit ...

Yeah, I was gonna say- that's a look we have to work at in VFX work to get "right" ;-)!!!!

Looks pretty normal to me. I would suggest a higher shutter speed. What did you shoot it at?
