Scoring Output/Capture quality

I'm not very experianced in getting/receiving opinions but this is one of the categories that seems to get very odd points sometimes. I mean, can you really give a ten in capture, if the video output looks like an average VHS but the video/idea itself is just amazing?

Kuronekosama's Meow Mix is a good example of this. The real video quality of this AMV was honestly said, bad but it still scored an average of 9.70 with it. There are other similiar ones out there.

the only way I'll give a nine or ten in video quality, is to see clean DVD source footage and keep the resolution in 720 x 480. Just because an AMV is funny it won't get any mercy form me and shouldn't get from anyone.

Agreed, that's how I score and that's how I hope everyone will score. I don't know about using 720 x 480 as the basis for 9 or 10 though, that's a little excessive. If the video looks nice full screen, I give it a 9. If it looks outstanding, I give it a 10.

The average for capture that I've given is a little under 8, which is still a little high but as long as the quality doesn't detract from the video, I don't score too harshly in that particular category.

I'd deduct a point if someone left it at 720x480 because they havent compensated from the 0.9 pixel aspect ratio. They should have resized to 640x480

Thats a bad example, get something where ops arn't rigged.

I've been given low score for capture quality on a distro encode which was as good as modern technology could allow... because they didnt like the anime.

Go figure

I don't know much about the 0.9 pixel aspect ratio but isn't 720 x 480 the DVD standard?

Tash wanted a better example, let's see...
Memories Dance - it surely doesn't deserve an average of 9.69
Engel - I mean c'mon! It's a VHS capture with a bloody distortion in the bottom. How in the hell can it get a nine?

Ignore the whole thing about the DVD aspect ratio in my last post...

Agreed, I would give Memories Dance (even though it's my third favorite video ever) about a 7.5 if I could. I'd give Engel a 6.

Many DVDs contain video that doesn't really fill the 720x480 (non-square pixels) DVD frame. Also, by resizing from 720x480 to 640x480 you're losing data; it would be better to resize to 720x540 (add pixels instead of removing them). Then, most encoders have limitations on what dimensions they can generate (must be a multiple of 8 or 16 or whatever). My current project is likely to end up at 720x544 in the high-quality XviD version, as a result of these issues.

With MPEG there are fewer choices for size, but at least MPEG allows non-square pixels, so you can keep the original DVD resolution...

It's a tradeoff between AR, PAR and data loss. This is why 640x480 is convenient.
