  1. 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
  2. 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
  3. i did send a pm back to you now :)
  4. 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
  5. Hi here is one more clip Regular 8mm https://vimeo.com/99496599
  6. 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.

  7. 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
  8. Here is a old less good quality Regular 8mm clip it´s from 1939 https://vimeo.com/86430617
  9. thanks:) the film was in very good shape and i guess the person that did film that did have good camera and optic
  10. 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
  11. 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
  12. 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
  13. ok sound good i guess i have to buy one :) Phil ok then i know
  14. i have been thinking my self to buy a Arduino or Raspberry Pi and a stepper motor and see how it all works the light sensor you did link was compatible with arduino :)
  15. i have seen this video that they use laser sensor called sensopart PS-L4 i think http://www.youtube.com/watch?v=LkygfyDCl44 i did see in some other picture he have placed the laser sensor diagonally i guess it´s because for example let's say if you look out of a window and you stand much more on the other side of the window then the window is not so wide anymore :) so i guess it get´s more accurate for the sensor to detect sprocket hole if the laser sensor hits the sprocket hole diagonally
  16. Thanks :) in the video i use IC Capture 2.3 you can download it here http://www.theimagingsource.com/en_US/support/downloads/ software called FireCapture works to you can download it here http://firecapture.wonderplanets.de/ in IC Capture 2.3 and FireCapture you have the option to enable trigger mode the hardware and trigger i use a hall sensor and i have a magnet glued inside the projector on the wheel so every time the wheel rotate and comes near the hall sensor it output 5v to the camera trigger here is a picture of the wheel and hall sensor here you can see the whole trigger cabel with hall sensor here is a better picture of the hall sensor here is the wiring diagram to build the trigger and i did copy it from here http://www.cine2digits.co.uk/
  17. here is my telecine in action :) https://vimeo.com/82866312
  18. Thanks :) the movie was from ebay i have 2 more reel´s left to convert this was reel number 2 Reel1: Hawaii 1970's. Asian american couple visiting the Isle. Sometimes features landscapes like in Lost, sometimes city skyscrapers, beaches, asian style gardens, and then a crusade in the port with militar ships moored, and many other sights from that decade. Reel2: South East Asia (Thailand, Taiwan, Singapore), 1970's. Magic trip throungh Buddist temples, river crusade like in Hollywood movies we watched many times, rising cities (very different from now) and incredible nature. Reel3: USA 1960's. This is an incredible document about the typical American family having trips to places like Universal studios theme park, Niagara Falls, National parks (featuring the amazing meeting with a Bear walking in the street close to the car). You will see strange looks like in Mad Men, typical cars and lot of things of the American history. here is some photos of the reel´s he did link on ebay when i did buy it http://s1082.photobucket.com/user/danielecarrer/library/Lot%20of%20Super%208%20reels%207?sort=3&page=1
  19. Thanks :) the transfer method is a home made you can see photos here http://www.flickr.com/photos/94271811@N03/ i run the film two times thru the projector one for low exposure and one for high exposure then i use avisynth script to vertical stabilize sprocket hole on the low exposure and then align high exposure to it then i feed the low and high exposure separately as Clip_A and Clip_B because now they are align in to the hdr function in avisynth and they come out as merge singel clip then i use autolevels function and last i use imagewriter in the avisynth script then it output it as image sequence all that i do in one pass in avisynth but it goes very very slow about 0.52 fps it take some time this film clip was 14985 frames so it did take about 8 hours next i do the denoise with avisynth and the speed is the same so it take 8 hours to
  20. Hi new film clip again :) some of the scenes have blown highlights https://vimeo.com/82497785
  21. Me again with some new test clips with Rodenstock APO-RODAGON D 75mm 1x f/4 lens and some tweaks on the hdr and denoise script avisynth Test 1 https://vimeo.com/81876713 Test 2 with little more denoise https://vimeo.com/81877336 here is the old version https://vimeo.com/73398189 i think i like the Test 1 better little more film grain left on it but there is some jittering going on do not know yet what does that
  22. Here is one more compare Rodenstock APO-RODAGON D 75mm 1x f/4(i did use f4.0 for even sharpness) http://www.flickr.com/photos/94271811@N03/11022515963/in/photostream/ Linos MeVis-C 50mm (i did use f5.6 for even sharpness) http://www.flickr.com/photos/94271811@N03/8601824763/in/photostream/
  23. Hi i did buy a new lens from ebay it´s called Rodenstock APO-RODAGON D 75mm 1x f/4 and i have to say it´s sharper then my Linos MeVis-C 50mm lens here are some pictures Rodenstock APO-RODAGON D 75mm 1x f/4 TEST http://www.flickr.com/photos/94271811@N03/11013222224/in/photostream/ Linos MeVis-C 50mm TEST http://www.flickr.com/photos/94271811@N03/8593778592/in/photostream/ and i have some other new pictures to of my diy telecine here http://www.flickr.com/photos/94271811@N03/?details=1 or http://www.flickr.com/photos/94271811@N03 i did buy this lens to Schneider Componon-S f/2.8 50mm and i did use it in reverse it was very close to the Linos MeVis-C 50mm sharpnes but Linos MeVis-C 50mm was beter but it look´s like Rodenstock APO-RODAGON D 75mm 1x f/4 is the best lens i have now for telecine
