Zak Forsman Posted September 16, 2015 Share Posted September 16, 2015 I used one of James Miller's new V-Log LUTs (AA20) for a moody look. This was shot at ISO 1600 because I wanted to see how bad it would look, given all the complaints about noise. To my surprise, this LUT does a fine job of suppressing it. It's a darker grade but there is more going on than that. A pass of the same clips with the Varicam V709 LUT follows for comparison. That's also the LUT I had loaded into the Odyssey 7Q+ while I was shooting. GH4 + Helios 44 + Metabones Speed Booster + ISO 1600 + V-Log L (-5, -5) + Captured in 10bit ProRes HQ + LUT AA20 by James MillerGRADED V709 So while Vimeo compression has hidden half the noise, I gotta say I'm kinda okay with how the noise looks. It gets pretty disgusting when you move NR above -5, in my opinion. But leaving NR all the way down let's the noise be fine and detailed, which I prefer to murky and glompy. I rarely shoot above ISO 800 but given the right context, the right kind of movie, I think it works. dwijip, mercer and Liam 3 Quote Link to comment Share on other sites More sharing options...

mercer Posted September 16, 2015 Share Posted September 16, 2015 What I like about this video has little to do with the look... Even though both versions look cool. I like the mood... It almost feels like you are going to turn a corner and find a dead body in one of those alleyways. Zak Forsman 1 Quote Link to comment Share on other sites More sharing options...

User Posted September 16, 2015 Share Posted September 16, 2015 Nice test Zak. I'd be curious to see how just how much different it would look if it wasn't recorded to the Odyssey. Can you comment on that? Quote Link to comment Share on other sites More sharing options...
AaronChicago Posted September 16, 2015 Share Posted September 16, 2015 Awesome. Did you notice any banding with 10 bit? In 8 bit I really only noticed it in the sky, and with HD 96fps. Quote Link to comment Share on other sites More sharing options...
Fritz Pierre Posted September 16, 2015 Share Posted September 16, 2015 Seems to handle ISO 1600 with no problem...did you shoot in 4k and is the Odyssey 7Q+ data hungry at 4K?...just got the Shogun and it does 43 min on a 240G SSD. Quote Link to comment Share on other sites More sharing options...
j.f.r. Posted September 16, 2015 Share Posted September 16, 2015 I heard this music somewhereA video game....... Also there's some really bad rolling shutter in those shots, that wobbly footage imo is one of the worst things I see in "amateur" footage.....

Flynn Posted September 16, 2015 Share Posted September 16, 2015 Don't you have a 2x anamorphic Zak? LA at night in anamorphic with vlog might make for a sweet vid. Zak Forsman 1 Quote Link to comment Share on other sites More sharing options...
TheRenaissanceMan Posted September 16, 2015 Share Posted September 16, 2015 Also there's some really bad rolling shutter in those shots, that wobbly footage imo is one of the worst things I see in "amateur" footage.....It's better than any of the other 4K hybrids. By a mile. Looks like the GH4 still shows those weird blobby artifacts around point light sources at high ISO. I really hope they work on that for the GH5. It's so wacky-looking and impossible to correct in post. Otherwise, great vid! Even though it's a throwaway test, your skill shines through in the editing, atmosphere, and music choice. Speaking of which...anyone who's played a Valve game should find the music familiar. It's from Half-Life, but now plays over Valve's studio logo when loading any of their titles.

Zak Forsman Posted September 16, 2015 Author Share Posted September 16, 2015 My biggest concern with V-Log right now is I'm seeing Magenta/Cyan blocking. It's easiest to see against a flat gray gradient, like a wall. Someone posted a comparison with Cinelike D that illustrated the difference pretty well, but I can't find it now. It's more apparent in the V709 version of my video. The DELUT verision seems to suppress it. Quote Link to comment Share on other sites More sharing options...

Zak Forsman Posted September 16, 2015 Author Share Posted September 16, 2015 it's possible they're not related. here's the post about the magenta/cyan thing. i'll do my own test to see if it exists in 10 bit. from my night footage, with the V709 LUT applied, the reds would go berserk with chunky noise and this unevenness looked like a similar/related issue.here's the post I read about the issue in 8 bit. http://www.dvxuser.com/V6/showthread.php?340370-Exposing-V-LOG-L&p=1986577386&viewfull=1#post1986577386A video game....... Also there's some really bad rolling shutter in those shots, that wobbly footage imo is one of the worst things I see in "amateur" footage.....haha, yeah, if I had left the soundtrack intact on the cut video, you would hear me mumbling "jesus fucking christ" every time it revealed itself. but last night I was more interested in color and dynamic range, so i let it slide.

Zak Forsman Posted September 17, 2015 Author Share Posted September 17, 2015 all right, i tested it for myself. 10 bit vs 8 bit. internal vs external. v-log vs cinelike and natural. and for me, it's pretty clear now what v-log is and isn't capable of on the gh4. i've got stuff uploading... will write it all up on my blog when it's ready.
