Passthrough & Greenscreen

metaverse Looking forward to it, thank you again

metaverse Thank you for sharing this. What I was trying to accomplish was to be able to manually insert my own custom BG on one of your new alpha videos. Because they are in alpha, then the normal keying of the green doenst work anymore. What I was asking is if there is a simple way for us to take one of your published alpha videos and key out the background on a program like premiere and add our own backgrounds. From my testing so far, without the original alpha channel you made for your videos, it's almost impossible to "reverse" this process on our own. What I was wondering is if you could share the alpha channel you created for those alpha scenes that we can download and use on premiere to add our own backgrounds on those videos.

metichemsi Oh, that's a little harder.
I can make a preset to reverse alpha to remove background, but will take some time.
Will try tomorrow

metaverse understood, you guys dont save a copy of the source alpha separately? Your software solution has you add the video and the source alpha separately before it spits out the finished product, I was thinking your team just has a backup of the source alpha for all of these scenes, we can simply use that to easily replace the backgrounds ourselves.

metichemsi We currently render the scene with alpha already in it.

metaverse Sorry so is what you posted a way to watch the passthrough videos through link? I've been waiting for passthrough for link to work for so long now. The video quality is soooooo much better through link for me, and I absolutely love the passthrough videos.

metichemsi then the normal keying of the green doenst work anymore

It does, you gotta turn the "A" off then you can move the sliders.

Vrsumo2017 thanks but I meant keying on a program like premiere pro, not the app.

metichemsi i see, the thing is we don't store alpha channel separately, but render the whole thing together as master + embedded alpha in the corners.
I will try to come up with preset for reverting / using alpha in the video to cut the background preset, but will take me some time. will keep you updated

metichemsi here, i made a preset for keying out background using alpha

metaverse I've been playing with that preset but masks never line up correctly always meshed together incorrectly and at wrong scales. Is that preset for the K2 pro camera or the modded R5C system?

metaverse disregard, I just realized what happened, for some reason your template is not meant to take the scale of the 190 r5c PT at full 100% I had to scale the file to 96% and everything lined up perfectly, weird but it works now. Thanks!

metaverse looks like the issue is that the template you made was for a PT video with the resolution of 7680x3840 and I am working with another SLR PT video that has a resolution of 8000x4000 instead, that makes sense why I had to scale down. Do you have a template that works with 8000x4000 or do the scales on all the parts follow a specific mathematical scale? some of them have strange aspect ratios that I would guess were found by trial and error unless there was a formula to calculate them. Thanks

Sandi_SLR Any update on making the male character a different color like keeping him greenscreen? When testing or using our own custom backgrounds in these videos we lose the ability for our bodies to show through passthrough. Can you either make the male a different color or return to filming these scenes with a fully nude male so these custom backgrounds scenes work?
