Thanks :)

Hi my camera can do max 20 fps here you can see my main scanner setup it does about 7fps that i use https://www.flickr.com/photos/94271811@N03/11007177505/ and i use hall sensor to trigger the camera https://www.flickr.com/photos/94271811@N03/10312776126/ and here you can see some HDR captures i have done i run the film two times low and high exposure and join them with Avisynth https://www.youtube.com/watch?v=o0tv4im6HPo&frags=pl%2Cwn https://www.youtube.com/watch?v=nCcKXjlwgRw&frags=pl%2Cwn https://www.youtube.com/watch?v=aQd5RWj3hrA

Hi i have test Photo interruptor sensor to detect sprocket hole and then trigger camera to take a picture and it works very good i think the RetroScan universal works the same way but the camera need to have fast exposure 1/2000 or faster because the film move constantly here is a movie clip when i test it i hand crank the film up to 18 fps no problem :) https://www.youtube.com/watch?v=ABlW4jvSruM&frags=pl%2Cwn

i did send a pm back to you now :)

Thanks :)

here is one more https://vimeo.com/101122130 i did now use DaVinci Resolve Lite some of the film scene where blue so i did try to do some correction

Hi here is one more clip Regular 8mm https://vimeo.com/99496599

i post my avisynth script that align two clips low and high exposer a=ImageSource("I:\tw2\N\tiff\image%d.tiff",start=1,end=28988,fps=5).ConvertToYV12() #Low exposure clip b=ImageSource("I:\tw2\E\tiff\image%d.tiff",start=1,end=28988,fps=5).ConvertToYV12() #High exposure clip c = Interleave(a, b) # here it merge the low and high exposure to even and odd frames a_cont=9.214285 #adjust this for Low exposure b_cont=0.08 #adjust this for High exposure a_ref = a.NonlinUSM(1.2,2.6,6.0,8.5).HighlightLimiter(1,true,1,true,100).tweak(cont=a_cont).GaussianBlur(VarY=1).MT_binarize(threshold=80).greyscale().invert() #adjust this for Low exposure if needed MT_binarize(threshold=25) and this NonlinUSM(50.2,2.6,6.0,8.5) b_ref = b.NonlinUSM(50.2,2.6,6.0,8.5).HighlightLimiter(1,true,1,true,100).tweak(cont=b_cont).GaussianBlur(VarY=1).MT_binarize(threshold=25).greyscale().invert() #adjust this for High exposure if needed MT_binarize(threshold=25) and this NonlinUSM(50.2,2.6,6.0,8.5) #return StackHorizontal(a_ref ,b_ref ) #Enable this only to see that Low and high exposure looks about the same and to do the adjusting to the settings when all looks ok put back this symbol # before return c_ref = Interleave(a_ref, b_ref) # calculate stabilization data mdata = DePanEstimate(c_ref,trust=0.01,dxmax=32,dymax=100) # stabilize c_stab = DePanInterleave(c, data=mdata) #Now the low and high exposure are align and now it separate low and high exposure frames b2_stab = c_stab.SelectEvery(6, 2) #Here is the high exposure clip a2_stab = c_stab.SelectEvery(6, 1) #Here is the Low exposure clip #i now input a2_stab and b2_stab to my HDR script and it does the hdr thing and output a merge singel clip :) you need this functions to function HighlightLimiter(clip v, float "gblur", bool "gradient", int "threshold", bool "twopass", int "amount", bool "softlimit", int "method") { #SetMTMode(5) enable this if you use MT gradient = default (gradient,true) #True uses the gaussian blur to such an extent so as to create an effect similar to a gradient mask being applied to every area that exceeds our threshold. gblur = (gradient==true) ? default (gblur,100) : default (gblur,5.0) #The strength of the gaussian blur to apply. threshold = default (threshold,150) #The lower the value, the more sensitive the filter will be. twopass = default (twopass,false) #Two passes means the area in question gets darkened twice. amount = default (amount,10) #The amount of brightness to be reduced, only applied to method=2 softlimit = default (softlimit,false) #If softlimit is true, then the values around the edges where the pixel value differences occur, will be averaged. method = default (method, 1) #Method 1 is multiply, the classic HDR-way.

Thanks :) i do have some clips still to upload to vimeo i have still not use davinci resolve light i have it installed but been to lazy to use it :) i mean to do little color correction all 3 latest clips i have upload to vimeo i have use exactly the same setting

Here is a old less good quality Regular 8mm clip it´s from 1939 https://vimeo.com/86430617

thanks:) the film was in very good shape and i guess the person that did film that did have good camera and optic

if i post more film clips i use this topic next time so i do not need to do new topic everytime i post a film clip :) so here is one more clip https://vimeo.com/85767429

Thanks :) the super hot highlights is in the film i can not do anything about that if i remember right i have test to do 3 different exposure but it did not help much but i have now a better hdr avisynth script so maby i have to test it again when i do the sprocket stabilize i do it only on the low exposure capture because the sprocket hole is the brightest and i align the high capture to it when i do the hdr The camera is a The image source camera DFK 23GP031 here you have a picture of it

Hi got a new TAIWAN & THAILAND 1970s Super 8mm cilp https://vimeo.com/85107570 i have some before and after denoise and sharpening pictures here http://flickr.com/photos/94271811@N03
