Wolverine-Hawkeye Telecine

[Mattias Norberg]

Thanks Mattias. Uploading the files now. In this scene the trees turned out too dark although the high exposure shows then OK.
Will send out the link shortly.

ok

i see now the hdr files going to download now

[Mattias Norberg]

i think i did get it to work better the Avisynth HDR script i did change from this

function HDR1(clip a_stab,clip b_stabb)
{
b_stab=b_stabb.TurnLeft().HDRAGC(max_gain =5.0,min_gain=0.5,coef_gain=2.0,coef_sat=1.25,MODE =2,shadows=true,protect=1,reducer=0,corrector=0.0) .TurnRight().ColorYUV(off_u=-12,gain_u=0)

t=a_stab.TurnLeft().HDRAGC(max_gain = 3.0,min_gain=0.5,coef_gain=2.0,coef_sat=2.00,MODE= 2,shadows=true,protect=1,reducer=0,corrector=0.0). TurnRight()

ab=overlay( b_stab,t,x=0,y=0,mask=b_stab,opacity=0.4,greymask= true,mode="Multiply",pc_range=true).ColorYUV(off_y =0,gain_y=30)
abc=overlay( b_stab,t,x=0,y=0,mask=b_stab,opacity=1.0,greymask= true,mode="Difference",pc_range=true)
ass=overlay(ab,abc,x=0,y=0,mask=invert(ab),opacity =1.0,greymask=true,mode="Blend",pc_range=true).ColorYUV(off_y=0,gain_y=0)

ab1=overlay(t,ass,x=0,y=0,mask=t,opacity=0.15,greymask=true,mode="SoftLight",pc_range=true)

l=overlay(ass,ab1,x=0,y=0,mask=ass,opacity=1.0,greymask=true,mode="Blend",pc_range=true).ColorYUV(off_y=0,gain_y=3)
ll=overlay(ab1,ass,x=0,y=0,mask=ab1,opacity=1.0,greymask=true,mode="Darken",pc_range=true).ColorYUV( off_y=-19,gain_y=22)
k=overlay(l,ll,x=0,y=0,mask=l,opacity=1.0,greymask =true,mode="Blend",pc_range=true)

return k
}

to this

function HDR1(clip a_stab,clip b_stabb)
{
b_stab=b_stabb.TurnLeft().HDRAGC(max_gain =5.0,min_gain=0.5,coef_gain=2.0,coef_sat=1.25,MODE =2,shadows=true,protect=1,reducer=0,corrector=0.0) .TurnRight().ColorYUV(off_u=-12,gain_u=0)

t=a_stab.TurnLeft().HDRAGC(max_gain = 3.0,min_gain=0.5,coef_gain=2.0,coef_sat=2.00,MODE= 2,shadows=true,protect=1,reducer=0,corrector=0.0).TurnRight()

ab=overlay( b_stab,t,x=0,y=0,mask=b_stab,opacity=0.4,greymask= true,mode="Multiply",pc_range=true).ColorYUV(off_y =0,gain_y=40)
abc=overlay( b_stab,t,x=0,y=0,mask=b_stab,opacity=1.0,greymask= true,mode="Difference",pc_range=true).ColorYUV(gamma_y=-200)
ass=overlay(ab,abc,x=0,y=0,mask=invert(ab),opacity =1.0,greymask=true,mode="Blend",pc_range=true)

####ab1=overlay(t,ass,x=0,y=0,mask=t,opacity=0.15,grey mask=true,mode="SoftLight",pc_range=true)

l=overlay(ass,t,x=0,y=0,mask=ass,opacity=1.0,greymask=true,mode="Blend",pc_range=true).ColorYUV(off_y=0,gain_y=3)
ll=overlay(t,ass,x=0,y=0,mask=t,opacity=1.0,greymask=true,mode="Darken",pc_range=true).ColorYUV( off_y=-19,gain_y=22)
k=overlay(l,ll,x=0,y=0,mask=l,opacity=1.0,greymask =true,mode="Blend",pc_range=true)

return k
}

the biggest improvement i did was to add ColorYUV(gamma_y=-200)

the fix i did was inside the HDR1 function


it´s faster to just use HDR1 function

but i did use HDR1 function + HDR2 function maybe it´s better

HDR2 function alone did work better if i did add this line in the beginning inside HDR2 function
b_stab=b_stab.ColorYUV(gamma_y=-90)




some examples
i did not use davinci resolve for color correction only avisynth for hdr and denoise

hdr 1


hdr1 + denoise


hdr2


hdr2 + denoise


hdr3


hdr3 + denoise

Thank you Mattias for your help. I am still looking at the results. What I noticed is that the images are 8 bit. The app that I wrote saves them as 8 bit although the camera settings are 64 bit.
Trying to change it to 64 bit.
But even if I save them as 64 bit the HDRAGC code runs 8 bit. Studying the source code runs 8 bit.

No problem it´s fun to help

maybe it´s possible to get it to work ok without HDRAGC

i did notice long time ago that if i use TurnLeft() and then HDRAGC and then TurnRight() i did then get rid off one error in the picture but i do not remember what that error was maybe it was ghosting error

it's all trial and error i'm no expert

I am still debating on doing the Hawkeye update to my Wolverine Pro.

I would like to upload a sample to the forum here via Youtube to get some opinions on quality.

My problem is the frame rate needs to be slowed down. What piece of software is best to change the frame rate without loosing quality? I looked up Film9, but cannot figure out how to change the actual fps number. I was going to use Virtualdub2, thoughts?

[Bruce Davis]

Hi Jason,
If you upload to Youtube it will be re-encoded to a lower quality, they use their own codecs to reduce file size.
You need to upload your pristine file some where else, like one drive or google drive etc.
You do not really need to worry about frame rate for checking the quality of your captures.
Post the URL to your video here on the forum.

Hello everyone, here is a reel that I test converted on my Wolverine Pro unit. Based on this result I will be ordering the Hawkeye camera today, but I wanted to get some opinions from the forum on the overall quality and grain/pixels. Please let me know what you think. This is an 8mm film.

Hi Jason. Lots of compression artifacts and sharply defined objects without smooth transitions. When I see the video I can tell right away that it is original Wolverine.
Some people do not mind that and are perfectly happy and that is OK. For me it is also just being aware of the flaws.

HI Stan, it is actually the Wolverine Pro 1080p model. Would there be a setting I am missing? I assume a new camera would improve the quality to a degree?

[Stan Jelavic]

You can try playing with sharpness. Make sure it is set to minimum although there were some issues with that on some models. Apparently sharpness had not effect. Believe there is a fw change to fix that but not sure ts been a while ago.
Yes, the Hawkeye would give you some improvements. Believe I have several side-by-side comparisons. Will have to dig one out.

[Stan Jelavic]

Still analyzing the HDR script Mattias. It will take me a few days. For now noticed that the HDRAGC does not do much for the hi images. For low exposure images it bumps up the gain. The blending does not seem to be right but still too early to tell. Looks like it does not include the shadow details from the hi images.

Okay I will play around with the setting over the next day or so. I have everything set to the default at the moment. I have looked around this thread and found a few comparison examples I believe. I will likely get back to you in a few days about ordering a kit. Thank you.

Hi Jason.
having watched your upload, I think you need to adjust the sharpness to medium. It is instinctively natural to opt for the high setting as we desire to maximise the quality but the high setting is simply too much. Also, the whites on the film seem a little bleached to me. I would adjust the exposure down to minus 1. Keep the picture as small as possible and don't use the inbuilt cropping tool as this causes deterioration to the picture.

A very nice man named James G Brown has a thread on the forum which links to a tool he has developed to adjust the speed of the film and to crop the unwanted edges. It is invaluable.

[John Kennedy]

I like your video also John. It did turn out very good. The videos that I took with my original Wolverine generally had issues. My main problem was the amount of compression that actually do not show up on your video. Maybe the quality of the film and plenty of light, not sure.

Hi Stan. Those kind words mean a great deal to me coming from someone with your undoubted wisdom and experience.

Funnily enough, the standard 8 footage from the sixties seems to fare much better on my Wolverine than super 8 from a decade or so later.

I have no idea why...

[Bruce Davis]

Hi All, good to see so much activity, I was just playing around with Photomatix HDR and used two of Stan's images 811.tiff 812.tiff, with standard settings in Photomatrix ans selected the Natural option.
By the way Stan the images I downloaded from https://drive.google.com/drive/folde...zT00JewKQT0GhS are actually in BMP format not TIFF.

The result is below :-
As a comparison the image HDR1 that was posted by Mattias is below:-
