Frame rate?

[TheHade]

How can I determine the frame rate of a Blu-ray I'm watching?
I own a Toshiba BDX1100KE.

It would depend on your TV, press the INFO button on its remote and it might give the information. Also if you can select a Real Cinema mode on your TV, if it has one then you're probably displaying 24Hz.

Your player will have a 24Hz option, if that's not enabled you'll be outputting 60Hz in most cases.

Get a Sony player instead

Thank you for your reply, chip75!
But I'd like to know the frame rate the Blu-ray disc was encoded with (23.976? 24? 25?). Do I need a BD drive to find that information?

You'll need a BD drive if you can't glean that information from your player or your TV.

Have you consulted that database on this site?

I think I found your remote, and there's a button called "Display" to the bottom left of the directional buttons.

In most cases BDs are 23.976, there are a few 24fps releases, but they're not the common. 25fps releases are more common outside the US.

A BD-ROM drive would tell you the information, with BDInfo or MediaInfo, software players like PotPlayer will tell you the information, but they won't play the discs without AnyDVD.

Not sure what info the DISPLAY button brings up on your Toshiba? Others like Panasonic players will give the information in most cases.

They have an on-screen info popup that displays frame rates - although you only get 24p, 50p and 60p, it doesn't go as far as differentiating between 24 and 23.98 - as well as video codec, audio codec and real-time audio and video bitrate readouts.

Oppo players do differentiate between 24.000 and 23.976.

It took me a while but I followed your advice and finally got one. Thank you, Naiera!

I'd never noticed it before to be honest with you ...

There is but this doesn't display the frame rate, unfortunately.

Yes, thanks again chip75! I wish this information (along with EAN, e.g.) were listed at Blu-ray.com! Is there a way to request that feature?

Yes, BDInfo has been very helpful for my reasearch.

It lists the stream, format, time, etc., but not the frame rate, unfortunately.

That's interesting. Thank you, Alister_M!

I guess the deep spec specifics aren't considered all that useful to 99.9+% of members. For almost everyone, 23.976 is exactly the same as 24 or 29.97/30 59.94/60. I do understand for some people running projectors sources via a PC that information is helpful, otherwise it seems most a Video Professionals detail

If you need to distinguish past the decimal then it's easier to just use BDInfo or see if the threads include the BDInfo details

EAN/UPC is available on most entries using the EDIT MOVIE selection

Maybe so, but in my opinion at least a rough estimate would be nice to know if a release is 24 or 25 fps, e.g.

Oh, I didn't know that. Thank you for pointing this out to me, hariseldon!

By the way, is there any way to play a 25 p DVD or BD at only 24 p?

Most if not the majority of the released UK entries do tell if it's a 1080p/24 or 1080i/50 encode -- at least where those items have been tested. Most of those entries are geared toward the main feature and often even if the feature is 24p, the extras might be 50i or even SD PAL (many of the UK Doctor Who sets, the AUS Buck Rogers) so it's still a bit of a guess. 50i encodes on the main feature are almost exclusively international TV productions and some older EU films. I honestly can't remember when EU produced films switched to primarily 24p

Many US players (non modded) will convert 1080i/50 to 1080/60 -- I'm unsure if those players can then go to 24p, but I'd imagine that would probably introduce quite a lot of artifacts. It's less common for unmodded players having the capability to convert DVD PAL to NTSC, but I think there are a few.

Unfortunately some dodgy distributors in the UK and other 50hz territories have a tendency to release BDs with 1080i transfers. It's become less common now but there's plenty of them floating around. I suppose they do it because they can then downscale the 1080i master for DVD, or because they're recycling 1080i masters that were prepped for DVD or HDTV in 50hz territories.

[hariseldon]

There are a few releases that may be downgraded especially in the 2007-2009, but most major studios and indies are going to release movies at the usual 1080/24 and and few EU/UK TV shows at 1080i/50 (like the BD of the BBC Planet Earth/Blue Planet/Dynasties, many Doctor Who series, etc).

Stay away from the 4th rate distributors and things should be fine

No, there is no way whatsoever to slow playback down.

Does 1080p mean it's 24 fps?

That's disappointing ...

I think 100% of the time. I don't think 1080/25p or 30p is part of the commercial bluray spec

25p sources can't be done directly so has to be done as described above and is output as 1080i/50 (though some players force or allow conversion to 60i)

I think 30p like the Todd AO version of Oklahoma also ends up being output or displayed 1080i/60. True 30p sources are pretty rare on disc though and most 1080i/60 presentations originated from Video sources

1080p means it's either 23.976 (which would be the majority of cases) or 24fps (I suppose to accommodate digitally-shot productions that were shot/prepared in that way). 25fps and 29.976fps is always 1080i.

UHD Blu-ray specs, however, support 25fps and 29.976fps at 1080p, and up to 60fps at 2160p.
