For film sourced from 24p, 24p assuming your components are high enough quality and cando this. For video, 60p as sourced at 60p.

I have to say that I see very little difference between 1080p24 and 1080p60 - even from a native 1080p24 source like BluRay. Perhaps this is because I use a very good scaler, or am just not sensitive to judder.

Thanks or the replies. I am using a Runco vx-22d and a Luminance Radiance.

I see on the display that it will say 1080p 60. Can I go into the menu and change this to 24 to compare?

To change the output mode on the Radiance press "Menu, Output, Configs, [config], Select Mode, Ok". Use the up and down arrows to select the mode then press "Ok" to select. You can high light "Select mode" and then press the "Help" button on the remote to display the help file for this menu item.

To link two user memories to different output modes so that you can quickly switch between output modes:

1. Press "MemA".
2. Link MemA to output Config0 by pressing "Menu, Input, Video Setup, [resolution], Out1 Select, Ok, Config0, Ok".
3. Set output Config0 to 1080p60 by pressing "Menu, Output, Configs, [Config0], Select mode, Ok, 1080p60, Ok".
4. Link MemB to output Config1 by pressing "Menu, Input, Video Setup, [resolution], Out1 Select, Ok, Config1, Ok".
5. Set output Config1 to 1080p24 by pressing "Menu, Output, Configs, [Config1], Select mode, Ok, 1080p24, Ok".
6. Save your new settings by pressing "Menu, Save, Ok, Ok, Ok".

Now you can press "MemA" to set the output mode to 1080p60 to watch video and press "MemB" to set the output mode to 1080p24 to watch film.

Best regards,

I agree with Ca1. I don't see much difference at all....

For BLU-RAY playback I prefer 24p 4:2:2 for its smoothness and pure untouched signal, I cant stand 60hz judder/stutter coming from pal 50 land......

Cheers.....

It is subtle. Here's a good test sequence I found. Get the BluRay "The Devil Wears Prada". If you are married you probably already have it! In the opening credits there is a scene with many people walking towrds a high rise in NYC. Look at their legs in 60P and again in 24P. You will see it there.

To answer the question, one needs to know if you care only about movies shot on film. For everything else, 60Hz is probably better. For film, the answers given about are applicable - small differences. I find it most noticeable on rolling credits. 24 Hz will be smooth 60Hz jitterer.

As others said:

The elimination of 3:2 pulldown associated with taking a 24 fps source and converting it to 60 fps is the only reason to do 1080p/24. Does it look better without 3:2 pulldown? Depends how sensitive you are to judder.

But really, the important thing to remember is: If your display supports 24 fps, by all means set up your source or scaler to output 24 fps if the source is 24 fps.

That decision depends on whether you are more sensitive to 24Hz fflliikkeerr or jjuudddeerr. Most people don't notice either. If you are sensitive to one or the other, make your decision based upon that info rather than what others think.

Note: The display has to be at the moment operating at 48, 72, 96, or 120 Hz. A display operating at 60 Hz must regenerate the 3-2 pulldown if/when accepting a 24 fps source.
