thebrothersthre3 Posted April 27, 2020 Share Posted April 27, 2020 I was just reviewing some old footage I took in flog at 2k and noticed some pretty bad smearing in the shadows. Really ugly. I thought maybe it was premiere doing something weird but resolve looks the same and it looks the same when rendered. Nothing done to the footage besides the Fuji WDR Lut. zoomed in at 220% to show the issue more but its certainly visible.

heart0less Posted April 28, 2020 Share Posted April 28, 2020 What codec and bit rate do you use? No problems here, though I shoot HLG @400Mbps All-I. Quote Link to comment Share on other sites More sharing options...

Video Hummus Posted April 29, 2020 Share Posted April 29, 2020 In a most scenes, without fast panning or water or lots of random-ish motion, modern LongGOP is very very good and offers better compression than ALL-I. I don’t see any difference between 150Mbps longGOP and 400 Mbps ALL-I from my GH5S unless the footage contains waves, lots of splashing water, or leafs blowing in the wind on a tree. HEVC (H.265) based LongGOP is even better and since most modern hardware is now incorporating HEVC acceleration hardware for easy decoding and encoding I see even less of a disadvantage to using it.

heart0less Posted April 29, 2020 Share Posted April 29, 2020 So, to get the most out of X-T3 you actually recommend Long GOP @400 Mbps, right? Quote Link to comment Share on other sites More sharing options...

You could actually use it before applying the color checker correction nod but there’s no point to it. For the gamma question, I can’t remember what gamma there is in Resolve. You can try gamma input « slog2 » as it’s not far from flog gamma and I usually do a blackmagic 4k gamma output as rec709 crushes everything. But most of the time, I put the same gamma Space input and output so the color checker only corrects colors and put me back to some rec709 color Space, and I adjust the gamma curve myself in another nod, so I have more control. But overall, if you don’t have to match your XT3 with other cameras, I’d suggest You apply the fuji WDR lut (the one which only affects colors, i can’t remember the exact name) so you’re back to a rec709 colorspace but with fuji’s touch. And then in another nod, you apply a custom curve. I have gorgeous results with this simple workflow. and finally, another method is to use color transform and put « gamma input flog » « color Space input rec2020 » gamma output « blackmagic 4k (same as above) » « color Space output rec709 ». There You go, 3 methods to normalize your flog image. I encourage you to use the second one if you wanna keep fuji colors. Thank you very much for this informative tutorial. I appreciate it.

Xavier Plagaro Mussard Posted May 31, 2020 Share Posted May 31, 2020 I dreamt it or Fuji opened their system to third party lenses, allowing AF lenses from other vendors? Any new in this front? I love the kit lens and have a 23mm f2 and 50mm f2. I am very happy with them, but would love more choices! Quote Link to comment Share on other sites More sharing options...

heart0less Posted June 7, 2020 Share Posted June 7, 2020 Weather today was awful and I didn't have much to do, so I grabbed a slider, designed and 3D printed by my friend, put a X-T3 on top, attached a projection lens to it and then took a couple of shots. I sat down to review them and thought: why not add some sound to it, play with it just a little while and actually publish the finished result? So here it is, really short mock-up opening credits I made. Not one of the most elegant timelines, but this have to do for now: Stathman, Emanuel and IronFilm 3 Quote Link to comment Share on other sites More sharing options...
