Ugo it looks to me that whoever took the digital picture has got a problem with his camera, as the image looks squeezed like 8mm scope prints, thus giving a distorted look to the projector.

Barry, I'm not sure this is what Ugo was meaning. Digital images are often distorted when not properly formated to be posted on the net. If you scroll down the auction page, you'll see the same photo posted correctly.

Now, why is it set to 20 fps ? For transfer of home movies?

Posted by Brad Miller (Member # 2) on November 04, 2004, 05:31 AM:

20FPS with a 3 bladed shutter yields 60 images per second. Video shoots at 30FPS (or if you want to get technical 60 "fields" per second). The result is a flicker free image.

To transfer 24FPS to video you would have to have a 5 bladed shutter. 24x5=120 which is divisible by 30 meaning again, no flicker.

Of course now that we have 24P videocameras, a film could be transferred at 24FPS with 1, 2, 3, 4 or 5 blades on the shutter and there would not be a flicker. [Big Grin]

Well there are a couple of problems with the ad. The first being that this is a "P" model and will not be able to record any sound as is stated! Also Elmo made a range of projectors called the TRV series that were all for Telecine. I have seen many ST180's of this line but never a GS. It looks like this may have been modded somewhere along the life of the unit. But I could be wrong, hey I didn't even discover the PC COM GS until 6 months ago!

Brad: thanks for explaining.

Ugo I see what you mean, I must admit on first looking at the advert I didn't scroll all the way down. Yes this GS is a strange beast, if it was meant for telecine conversions, shouldn't it be 25 fps for PAL (Europe) format transfer, as this is the rate PAL runs at. I'm stumpped why it should be proudly displaying 20 fps telecine, anyone else seen a unit like this before (or marked like it, anyway!).
