8mm/16mm transfered to DV50

Well it's really the best option I've got at this point.
And i think the fix should be pretty simple. Either wait till I can get the HVX and film in 18fps, or I just find a projector that runs at 12fps, record in 24p, and correct in post.

Many home movie projectors use a 3 blade shutter, so 3 x 12 FPS = 36 Light Pules per second.

My favorite trick is to adjust the projector to 20 FPS; 3 x 20 FPS = 60 light pules per second. This matches the field rate of NTSC.

While you can project the image onto a white wall or sheet of paper and video that, BUT any pattern on the wall or paper will appear on the video. OK, it works, but as far as quality, it's not the best way possible. When I tried it, adding a bit of light to "fog" the projected image lowered the contrast and made the image look a bit better. This "fog" light is shined onto the screen and is the brightness level of two nightlights; one on each side of the projected image. This helps, BUT too much "fog" light will raise the black level to dark gray and look bad.


Physically the rez of 8mm is between 50 and 80 lp/mm. Beware, this talks about pairs of lines while video talks about lines. So in video-speak you would talk about 100 to 160 lines per Millimeter. A Super 8 frame is 5.36 mm wide which equals appr. 600 lines max. over the full height of the frame (4.02mm) and appr. 600 lines max. horizontally in a square as wide as the frame is high (which is the way, rez is measured with video).

In theory Super 8 footage should be sharper than SD video, but from what I recall, it always looked a bit less in sharpness than SD video. Maybe because the footage came from cameras that had the 50 lines per mm lenses.


It's a pity that no one makes an 8mm/Super 8 movie film scanner with a geared stepper moter to move the file through frame by frame and generates a video file on the computer. With 12 bit 4:4:4 color depth and the right software, it should produce really good results. My guess is, it could be done, but the cost would be high.

it sort of been done - all depends on the camera's you put on it.. and it does cost $$ ...

according to JK -The continuous tone image in Super 8 frame size does not contain more information that can not be stored into 1440 x 960 frame size...
 
stretch a piece for canvas across a wood frame, paint it flat white, you'll have a nice screen for small money. should give a better result.

That's been done. Look here, Bob: www.moviestuff.tv/8mm_telecine.html
