  1. Thanks, jcs and sudopera. 

    @jcs but, but, but what about macroblocking and colored noise? and how do I ADD noise? are there actually products on the market for adding noise? It sounds absurd really - I don't think I could watch my clips if they were any noisier than they already are!

    On top of the page you have free film grain for download, here is the link:

    http://www.vision-color.com/free-stuff/

    Put the clip with grain on top of your main clip, set the blend mode to overlay and adjust opacity to your liking

  2. Okay, but whether I add grain before or after the LUT, how do I know what FCPX is doing, since there are no nodes, I don't know what it's prioritizing! And is there a difference between applying the LUT to an adjustment layer rather than directly over the clip? I thought adjustment layers were just for convenience - you know, to apply the same look to a bunch of clips at one time rather than individually.

    As I understood, if you want to color correct footage before you apply the LUT, you have to put it on the adjustment layer because in fcp effects applied directly to clip always have priority over color board so RT adjustment layer is a workaround for that. If you use scanned grain as a separate clip above your main footage and put LUT above those two clips on the adjustment layer, then I think LUT is the last thing that affects the image.

  3. @jcs but... Sherif says if clips aren't denoised before applying LUT, you can get macroblocking and colored noise (actually, I've been shooting with NR at lowest setting and not bothering with Neat Video, and I never noticed these defects when using LUTs- not to say they weren't there), but it's the banding that annoys me. So - add noise first - how? Or are you pulling my leg?

    Maybe you could try to denoise, then apply grain directly to clip and put LUT on the adjustment layer above the clip.

  4. @sudopera very nice clips and nice design too. A pretty talented guy, that Sherif Mokbel. I already have several packages of LUTs, but I may pick these up too sometime. I tried his method with Osiris Jugo, that is, denoising with Neat Video before applying the LUT and adding some grain afterward, and got very good results. But when I tried uploading to YouTube to share, the whole clip was dark and reddish looking. I may try again this afternoon. He also confirmed what I'd already suspected - that LUTS can introduce banding: I'd already seen it in the forehead of one of the musicians in my latest video. I was hoping that adding a bit of grain would help, but not at all.

    I saw no issues with Jacob Nielsen's 10bit footage, only thing that I noticed is that all the film stocks (didn't try Lomo stocks, fcp crashes) except Kodak Vision3 5219 made the lips and cheeks of the girls in Jacob Nielsen's footage look dark brownish red, but in reality the color is pinkish. Kodak 5219 looks nice to me, colors are right and the change is subtle but footage loses some of that digital look, I think it's a good starting point to my grade. I don't own a GH4 so can't test possible banding issues.

  5. Sudopera, that's an awesome tip. I hadn't heard of the RT adjustment layer, thanks for that. One major advantage that your method has over my idea of using compound clips, is that while you are doing the pre-LUT colour grade, in the Viewer you can see the effects of your grade after the LUT has been applied. When you're inside a compound clip, the Viewer only shows the results of that layer, and you have to exit the clip to see how the  primary grade looks after it has been through the LUT.

    I saw your post earlier and thought maybe there is some way to have an adjustment layer in fcp. Then I googled it and here it is, great stuff :)

  6. I dont know about using them on the GH4 but I will never buy them again. I bought 6 of the Micro SD Cards for some in car cameras for the Baja 1000 that our company was hired to help with for a team. They failed about an hour into filming, sad but good for us the team didnt make it much farther then that so it wasnt as bad as it could have been. 

    Thanks for the info. It seems that it could be one of those hit and miss situations because they have 5yr warranty.

  7. No its the nature of promist filter which has very fine particle that will diffuse the light a little bit. So more of it and there will be more diffusion effect. Shane hulburt has a nice article on the different filters on his blog.

    I believe Inazuma's question was how there is no glow on the bulb in the shot without filter.

  8. All I can think of is that the bulb is dimmed or lower wattage, maybe some milky coating on the glass. Probably someone has a better explanation.

    Edit: Also I suppose that everything is placed further away from the black background, so light from the bulb doesn't spill on the background.
