My guess is that it's a screen limitation and that I'm perhaps looking a little too closely. 
I don't notice the effect on my iPad with the same movies, but it's not a deal breaker. The flickering worries me a little more, but I'll wait it out and see if anyone mentions it as well. There's a user on the B&N forum asking about it, but no one seems to have a response. |
That dithering isn't a screen limitation. That is an MPEG artifact due to the encoding. A higher speed or higher resolution video would help. I encode all of my videos at 800x488 and 24 frames per second, as long as the source can support it. The technical term for "dithering" in an mpeg stream is macro-blocking, if you complain about your cable feed, use that term so the techs write it up correctly. The NOOKColor screen has a higher pixel density, you will notice artifacts present in video because of it. It is the same reason images look sharper on it then on the ipad.
The nookcolor doesn't rescale images down for its desktop, which is a wee bit annoying. What I do is resize them on my PC before transferring them over. It is the best way to get quality images.
