Hi Mattias,

Interesting result!

How do you see your technique with other transfer technique such as Tobin, MovieStuff, or Fred's.

Unfortunately your experiment is using 18 fps and amateur films. So it does not reach the max result.

Should you be able to get packed films (which is always 24 fps and no camera shaking) or at least trailers of Hollywood films, we can then compare your technique with professional transfer system. Can you?

Thanks

my technique is very slow because i run the film two times thru the projector to get the low and high exposure

i have only cartoon as packed films and i have a super 8 test film

here is a picture of it

Yeah, looking at "Thailand and Taiwan" clip, although the quality of the still frames (after denoised and sharpened) are very good but when it is playing, the camera shaking and the 18 fps make us dizzy, so we cannot get the full performance of your technique.

BTW the SMPTE scan you make is around 294 kb/frame. So 1 sec at 24 fps will be around 7MB. This means a 50' film at 24 fps (2.5 minute/150 seconds) is 1 GB ! [Eek!]

Your "Thailand and Taiwan" clip is around 25 minutes. I downloaded at HD quality and get 864 MB. So this is still highly compressed, isn't it?

But should we be able to have a terabytes hard disk and super fast computer, can the resolution still go higher than 294 kb/frame?

The original SMPTE scan frame is in bmp format and it´s 5.6mb big

but now i capture to tiff format and it does have a lossless compression LZW so it get little smaller between 1.5mb to 3mb files

the "Thailand and Taiwan" clip in image sequence is 28981 frames and 132gig

the "Thailand and Taiwan" clip that i did upload to vimeo is 4.5gig and max i can upload per week to vimeo is 5gig

i did use Megui encoder setting was
very slow
Tuning:Grain so it preserve the grain little better
Quality:17.7
AVC profile:High
AVC level:4.1

but vimeo encode it again so the quality gets worse :/
