I'd be curious to know how some of you are so confidently dismissing the video quality on a product you haven't even seen in person.
Not to say that it will be better than the PSP for that specific application (it won't be), but...don't you think it's a little ridiculous to be reviewing the new iPod NOW?
Specs say a lot about a product, as long as they are accurate and considered all together.
If I take my Apple aluminum 23" Display as my gold standard (not the best one), and on it display a 2.5 inch diagonal image encoded to 768kbs at 320x240 16-bit color (ipod video's max output) using an H.264 codec, I can at least tell you that the Ipod video's image will not be much better than that. This assumes a dot pitch, pixel response time (16ms for Apple Displays), and contrast ratio no greater than that of the Apple Display. The above example serves as an upper limit of the iPod video's quality.
Now if they somehow made the screen sharper than the Apple HD cinema display (i.e smaller dot pitch and higher contrast ratio), then this would offset things a bit and improve the subjective video quality.
In short, anyone who's used to working with video and has experience encoding in various formats can make a pretty damn good estimation of how good the iPod video will "seem". Keep in mind that the iPod video's resolution is best suited to 4:3 content such as TV shows, and that any cropping/letterboxing will reduce the usable resolution quite a bit. This is a crucial consideration for those planning to watch 16:9 videos on the go. The PSP allows user-encoded video of up to about 368x208 (using the free easy-as-pie-to-use app "PSPrez" to add a 320x200 header to the file after it has been encoded in order to accomodate 16:9.
This may be more than most people need to know, but someone chancing upon this thread may find it useful info to bring to bear upon their purchasing decision.
Now if only I could:
1)Find a way to hook up the PSP to my 60GB iPod color, and
2)Find a way to encode in the PSP UMD's ".PMF" format (I already have the PMF player) so as to overcome Sony's memory stick resolution restriction as fully utilize the PSP's 480x272 screen resolution.
These would make for up to 60GB of UMD-quality movies on the go.
Over and out.
