Image comparison: Go

1:27 PM / Blu-ray / DVD / Comments6 Comments

I generally don't do direct comparisons between DVD and Blu-ray releases, because I tend to feel that there isn't much point. Even the weakest BDs tend to improve exponentially on their DVD counterparts (unless we're talking about a standard definition upconvert like Universal's shameful HD DVD release of Traffic or Optimum's disgraceful Escape From New York). Every now and then, though, a BD comes along that looks so drastically different from its standard definition predecessor that a closer look is warranted. The recent BD release of Go, derived from a completely different master than the old 1999 DVD, is one such title:

Not really about Go which i haven't seen yet.

Regarding The Descent - Australian Edition. I bought an Oppo BD-83 Multiregion player which arrived today. I didn't switch to UK region and have left it alone on the American region setting for now but the film plays perfectly without a hitch.

Now here's the thing. The Oppo reports it as a 24hz playback. It reports other discs as 23.976hz.

Now 23.976 is the correct playback for films on Blu Ray and i know some discs have been mistakenly authored at 24hz. Could The Descent be one of those discs and what issues would be noticeable on such a disc.

I'm pretty sure the Oppo is reporting everything correctly as other discs i tried reported 23.976.

Have you checked your disc ?

I think you might see some dropped frames if the player does a strict 23.976fps.

I too have few 24fps BLUs and don't see any anomalies.

Foxy:

It never occurred to me that this was a straight 24 fps (rather than 23.976 fps) disc. If your player is reporting it as such then presumably this is the case (the link posted by LGANS316 would appear to be further confirmation). I can't claim to have noticed any dropped frames on either my PS3 (back when it still allowed the disc to play) or my DMP-BD35, but I've no idea how these players handle 24 fps content and how this compares to other players.

Shame about that but i think the Oppo should handle it fine without issues.

I did notice in the bottom black bar area a small halo along the edge of the black bar which i understand from your site is indication of a low pass filter which is another shame.

Foxy:

On The Descent? There shouldn't be any haloing on this title, especially not on the edges of the letterbox bars. I went through this disc with a fine toothcomb and didn't spot anything of the sort. I know I probably don't need to ask this, but are you definite that your player or display isn't applying some form of edge enhancement or softening behind your back?

Foxymulder: 24fps authoring is not a mistake - it's completely within the BDMV spec but is almost never used.
23.976 is actually the incorrect (but equally legal) speed. It dates back from the standard-def days, but is still used for convenience. Discs authored at 24fps are playing back at the correct speed - although 23.976fps is only going to equate to about half a second's worth of difference over a 2-hour film, or something tiny like that.

All BD players should handle both rates with no problems.

BTW, how are you finding the BDP-83? Oppo are asking me for feedback for the European version but I've found very few problems so far.
