Fire Effect for a Fantasy Project
Nudist Elegan posted a topic in Visual Effects CinematographyHi there, 15 years ago me an some friends of mine worked on a corny little fantasy project (http://www.candlekeep.com/library/articles/tdod.htm) that was never really finished. I am now working to restore one scene of that project to use it a a template for my film music compositions. Although I am making good progress in re-cutting and dubbing that scene, I am still lacking a visual fire effect for one very short sequence and don't how to implement that kind of vfx. Here is that short sequence: Do you know any small tool/program (best free- or trialware) to quickly create some kind of a ray of fire (until 0:04) and some gout of flame (from 0:04 on) around these little monsters? It doesn't has to look particularly good, it just has to be recognizable. If you want to try it yourselves, I've uploaded the sequence to dropbox: https://www.dropbox.com/s/op1crkcjxkv1ezi/Feuerzauber-Effekt.avi?dl=0 Best regards and many thanks in advance Dustin
Fishing wire for on camera hair effect?
Lindsey Sitz posted a topic in Visual Effects CinematographyHey All, I am directing a short comedy, "Cowlick" (https://www.facebook.com/cowlickfilm), and I need my lead character's hair to stick up like alfalfa from "The Little Rascals." The cowlick will pop up while on camera (meaning we need it to go from shellacked to his head to pointing up sky-high). We are thinking that attaching some type of fishing wire or thread to a well gelled "cowlick" might do the trick, but wanted to see if anyone had better suggestions. We have a test shoot coming up and will be able to try just about anything. My lead's hair is jet black. Thanks so much!
Sony Raw Highlight Banding/Posterization Issue
Hayden Mason posted a topic in LightingHello everyone. I recently shot a music video and have run into a bit of an issue with the highlights. One of the hero props on this one was a set of floating, glowing orbs a la John Carpenters "Starman". The characters had them in most scenes. Images attached. I was shooting on a Sony F5 with the Raw recorder. We also had proxies at XAVC 2k going to SXS cards. I rated the camera at 1250 most of the time to lessen noise, but when dealing with extreme highlights went to 2000 to have the most headroom. No LUTS were baked in, and I shot S-LOG2 Both the proxies and the RAW recordings have this issue. It shows up in Sony RAW Viewer and in Premiere CC. It shows up when looking at the RAWs and the SXS XAVC proxies. We decided early on to fly an actual LED light source on strings and do our best to hide the wires (which were also powering the orbs) It turned out great and we were ecstatic on set. Being able to key light with a moving source that was also a prop was amazing. However, when looking closer at the captured footage we found that the banding and pixelation around the orbs was terrible, especially when pushing the exposure towards the dark end. Quick movement seems to accentuate the issue. The odd thing is that the frames themselves seem fine, only when playing back do they look odd. The paused frames are clean of banding and posterization. I figured with 16BIT RAW we would be fine. It was obvious we were clipping the highlights. We tried to do so whenever possible to avoid too much compositing. Most modern digital cinema cameras aren't film....but highlight roll of is quite decent nowadays. What I wasn't expecting was terrible banding and posterization. Here is a clip (prores export, not de-squeezed, Slog) that shows the worst of it. It happens a lot. You have to watch in HD to notice the issue. https://youtu.be/vbKAWkfgCA8 Notice the posterization on the orb as it descends and on his face as it crosses around his back. We had planned to composite a VFX orb over some of the blown white highlights anyways. So, I would imagine that smoothing the banding in post might be an option, but it even shows up on hands and faces that get too close to the clipped highlights, as seen in this clip. I have no idea how to fix this issue. Is it something debearing or reincoding may fix or am I just out of luck? Im no expert, but I assumed the camera would be able to handle some blown highlights. After all, clipping windows, little hot spots, and clouds can look fine on this camera in my experience. All of my research pointed to the ability to wrangle down highlights in post. If anyone has any helpful words it would be most appreciated. Im not the most tech savvy at this point in my career, and even if this project is unfortunately hurt by this issue I would love to know why it happened and how to avoid it in the future. Or if anyone has any pointers towards a fix/workaround. My hope is that is an issue with post processing and not something that the raw recorder or F5 did internally...Like I said, the frames themselves are clear of the issue, it is only when you hit play that the digital garbage appears. Thanks so much for your time!

Film directors and Special Effects.
Ronald Carrion posted a topic in Visual Effects CinematographyMy question is how much of SFXs a director must know in order to make a movie? Is he supposed to have a great deal of knowledge in this field before embarking in such kind of projects? Do they teach special effects for directors? Is that something that the cinematographer must know? Thank you for your time.
Film directors and Special Effects.
Ronald Carrion posted a topic in DirectingHi everyone. I am about to start the 2 years of film studies at LACC and my goal is to become a film ditrector. My likings, which used to be quite broad, have narrowed down to movies where especial effects are of the essence ( Life of Pi, Transformers, Pirates of the Caribbean, etc.) My question is how much of SFXs a director must know in order to make the movie? Is he supposed to have a great deal of knowledge of this field before embarking in such kind of projects? Thanks.
