Here's the original: [...] fred.

While the overall quality of your results seems to be much better than mine, I do manage to get the sprocket holes EXACTLY lined up from one frame to the next so there is no ...

[...] this script works very fine. [...] Fred.

Thanks. I'll give it a try.

I noticed your new original sample on the "Auto-Processing" topic, (Maybe I should reply there). While the overall quality of your results seems to be much better than mine, I do manage to get the sprocket holes EXACTLY ...

Very interesting to examine the artifacts from this approach - thanks for the clip. Does anyone else see an overall waviness? I see it most noticeably in the grass on the long shot where you see the carriage from behind. Looks more "rippling" than "breathing".

Jim, I wonder if this is from non ...

Edit: I took a better look at your site, I'm very impressed about your knowledge both general and about writing software. How do you deal with the framerate pulldown? I think you can help me with my Avisynth script to do the pulldown. (See my 'auto-processing' topic)
Fred.

:D This is actually ...

Again, this is the first time I see someone producing good results with a scanner.. Sharpness is very good, but a little overexposure on the whites...

Yes. Getting the contrast right is the most difficult part of this. I've been trying to figure out the right way to do this but I haven't come up ...

OK. Per request I added a DivX clip that's a piece of the original.

Roger,

I didn't realize who I was talking to. I've been reading about your products. You have some great stuff available. How open is a WorkPrinter? Could I do my own processing of the raw scans? What is the resolution per frame and dynamic range per pixel of ...

Interesting project. I am certain that scanners will eventually get good enough to do this.. Just some observations: I noticed in the sample movie that there is some fairly obvious pulsing of the image exposure, as if it were shot off of a projector with the shutter out of phase of the video. What ...

oh, i didn't think it would produce as good images, but if it says 3000 dpi you should get that, shouldn't you?

How about if it says 4800? Then should you get 3200? :D

I wrote the following about the quality of these cheap scanners a while ago; when I was working with an earlier Epson model ...

One more thing - I thought about a Film Scanner (I wanted to try a Nikon Coolscan) but I couldn't get hold of one for testing and I wasn't going to lay out the $600+ on a hunch. Since it's a closed box I didn't know if I could pull the film throught it. If it's faster and I can actually do it I ...

i don't know how you do the sprocket detection exactly, but finding two holes, one on each side, and then linearly interpolate the others should be faster and result in perfect registration assuming that the film was properly perforated.

I use a linear interpolation using: 1) the location of the ...

Thanks for the links. I was going to do this originally with a stepper motor but I found them difficult to work with (I'm not very good at either mechanics or electronics). My initial attempt at the film forwarder began by pulling the stepper and controller from an old 5 1/4" floppy drive. Now that ...

Per the request, I added a couple of sample frames to my site. I do not link to them from my main page but you can see them at these URLs:

I'll put a few full frame JPEG samples out there tonight.

Petteri ,

The scanner is slow. It takes about 8-10 hours for a 50 foot roll. It takes upwards of 3 days (sometimes less) for a 400 foot reel. I'm guessing that clip is about 1/2 a 50 foot roll (it's actually an excerpt from a 400 foot reel) so that scan time was about 4-5 hours for that much ...
