Re: More film clips
I have never seen reg8mm look that good! Is this one of those multi pass scans? It was really fun to watch a slice of life from 40yrs ago at that quality

Thanks
yes i do allways multi pass scans to be sure i get everything

Wow 8mm look 's like a time that now gone for ever? when there was still a Dream !chrisgavin wrote:Great footage, amazing transfer, well done indeed.

Re: More film clips
Looks genus great transfer to .....Any idea what camera it was?
Re: More film clips
Thanks
i do not know what camera was used because i did buy this film from ebay

Re: More film clips
Nice job on the transfer…colours look amazing.

Is the multi pass product as simple as footage scanned multiple times at different exposures, then matched frame to frame on the same timeline?

yes it works´s very easy i merge the low and high exposures ex all even frames are low exposure and all odd frames are high exposures then i use stabilize and then they align correct then i separate the "even and odd frames" = separate low and high exposure framesTscan wrote:MattiasN wrote:Thanks

here is the avisynth script that does it
Code: Select all

#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)

#i now input a2_stab and b2_stab to my HDR script and it does the hdr thing and output a merge single clip :)

Re: More film clips
This is very useful! Thanks for sharing the scripts
Re: More film clips
no problems
hope you get it to work

Re: More film clips
Thanks for posting, I've been wondering about the quality of regular 8mm vs super 8, and I went ahead and got an old regular 8mm camera. This footage is reassuring, it looks very crisp. Obviously you did a good job with the telecine, but the footage also looks very good.
