Projector - Smooth Motion?

Hi there.

Is there a setting I can enable that will smooth out the video?

Projector - JVC LXUH1

Source = PC - 24hz video.

It seems that there is some noticeable motion hiccups.

For example, anytime there is somewhat slow panning or objects moving.

I believe this is mitigated on TVs by using frame interpolation or something like that.

I don't see any setting on the PJ for this. I was wondering how this is handled, or if this is just part of using a PJ

Refresh frequency output of the video card must be in sync with the frames per second of the video:

23/24p for 24fps bluray original movies
25/50p for 25fps pal system video or dvd
30/60p for 30fps ntsc system video or dvd

Hi there
The source switches to whatever the frame rate is in the video file.

It’s not like it isn’t working right. I may just be used to smoother motion from my tv.

I couldn’t find anything like frame interpolation in the settings.

On my Sony projector I think the motion setting True Cinema is the best setting for movies. Not sure what options are available on the JVC but I imagine they have a recommended setting in the manual.

Smooth motion is another name for digital frame interpolation. To have this feature a projector requires an added processor to perform the interpolation and not all projectors have one. I don't see anything in JVC's specifications for the LX-UH1 that suggests it has an added processor for DFI.

There is nothing in the manual which suggest that it supports creative frame interpolation in any form...

http://www33.jvckenwood.com/pdfs/B5A-2810-02.pdf

JVC specifically calls this Clear Motion Drive (CMD) on their projectors, and it is referenced on page 42 of their DLA-X590 model...
http://www33.jvckenwood.com/pdfs/B5A-2360-22.pdf

So, no CFI (or CMD) on the model you are using from all appearances.

Oops, I said digital frame interpolation (DFI) instead of the correct creative frame interpolation (CFI). Didn't mean to coin a new phrase.
