Standard-definition & Hi-definition film capture of 16mm film (1) (Updated a year ago)
This clip offers a comparison in picture quality between Standard-definition film capture (at 720x480 pixel resolution) and Hi-definition film capture (at 1836x1377 pixel resolution). The same KPIX-TV 16mm positive reversal news footage from December 22nd 1971 was used for this demonstration, featuring sequences from the premiere of Dirty Harry in San Francisco.
The screen has been split, with the left hand side featuring a Standard-definition (SD) capture and the right hand side featuring a Hi-definition (HD) capture. It should be noted that the SD capture was done in 2009 by Monaco Labs using a DFT Quadra telecine (native 720x480 pixel resolution); the HD capture was done by Image Trends Inc. in 2012 using their ScanMaster 4000 scanner (native 4872x3248 pixel resolution, rendered down to 1836x1377 pixels). The SD capture was blown up 2.68 times in Final Cut Pro to match the screen size of the HD clip. The online screener is an mp4 video compression (H.264 codec, 2000kbps, 768x576 SD), produced in Final Cut Pro 7. The HD picture was cropped at the edges to match the SD frame. Different choices were also made by these film labs for the scene-by-scene color correction and Image Trends used Digital ICE restoration software to remove surface defects from the picture. Monaco's master video output used for editing in Final Cut Pro was a 10-bit uncompressed QuickTime file; Image Trends, Inc. outputted to a ProRes 422 HQ video file. See part 2 for a slightly shorter on-screen comparison of the respective sizes of these SD & HD captures, to scale:
