Woody Disc 1 Cartoon 2: Woody Woodpecker A

"Woody Woodpecker" (1941)
Transfer Quality: ACCEPTABLE



The color balance on this cartoon is very good, even though the contrasts are boosted a bit. Woody's red and blue are under control and don't glow like in other cartoons. DVNR is only in evidence in fast pans, but the heavy compression rates cause macroblocking throughout several scenes in this cartoon.



These images are examples of macroblocking. The scenes that are affected by compression artifacting like this have macroblocking sprinkled through as many as 10 or 20 frames.


This is one of the few DVNR artifacts in this cartoon. Notice how the horizontal line is breaking up during the pan move above and is solid when the camera move ends below. This is a held cel, so the ink line should be identical.



This scene exhibits the worst compression artifacting in the cartoon. The entire scene is riddled with frames that contain macroblocking.


This is as good as this cartoon gets. Overall, a very good image. It's a shame that the compression mars an otherwise good transfer.

Woody Disc 1 Cartoon 1: Knock Knock G

"Knock Knock" (1940)
Transfer Quality: GOOD



Overall the transfer on this cartoon is very good. There's some macroblocking caused by overcompression and the contrasts are boosted, but the DVNR artifacting is almost non-existent. If the whole set was as good as this cartoon, it would be great.


The DVNR artifacting is extremely minor. Notice the difference in weight of the horizontal lines on the drainpipe during the camera move as opposed to the static shot of the same held cel.


Compression macroblocking is the biggest problem, and it only affects the bright blue and red of Woody when he is moving a lot.

This is a typical scene from this cartoon. The color balance is quite good- just a little too much contrast/saturation- easily corrected for with the color controls on your TV set.
