How to display videos fluently? (e.g. 25 fps movies on a 60Hz TFT)

Ice =A= · 14th June 2006, 17:20

Usually a video with e.g. 25 fps will result in jerky playback on a TFT monitor with 60 Hz refreshrate (or any monitor with a refreshrate which is no integer multiple of the framerate).
I do know "Trimension", which is a standard to compute new images in between the normal ones to make playback more fluent and smooth, but unfortunately it's only been implemented in WinDVD7 and there it works only with MPEG2 and not very reliant...

Anyway, you should try a very impressive demo here (just download and execute):
http://www.trimensiontech.info/bin/T...ionDNMdemo.exe
(Edit: It's not actually the real thing, but it shows what Trimension is capable of and how much video quality can be improved. You can test Trimension with WinDVD7 trial and some MPEG2 videos however...)

I'd like to know if there is any other program available, which has a similar effekt?!
Thanks!

The demo is a bit of a cheat. They have the whole frame panning, which means I could easily interpolate the frames just by shifting the whole frame horizontally. They need to show some real material, with just objects moving.

That's not a demo of Trimension, it's one picture scrolling at 60fps and another picture scrolling at 25.

True, but on the same page you can download real MPGs (that same video actually), and I tested it with WinDVD.
Believe me (or test it for yourselfes), it looks just like the "demo" and is very impressive indeed! (I could be wrong, but to me it looks even a little better.)
I just postet that demo link because I thought you would like to see what I meant as fast as possible instead of downloading a 40+MB WinDVD trial and some video files.

Well.... I suggest making sure a screen can support higher refresh rates before you buy em....but I know its hard to find on high rez & notebook displays.......

That's a good idea, but I don't know a single TFT display which can go to higher refreshrates then 70Hz, and 75Hz would be good for 25fps PAL standard.
I also don't know if you can sync the video to your monitor refresh rate that easyly (after all the fps often are no easy to handle integer numers)...

I tried recently to lower the refresh rate to 50 Hz, but with the normal nVidia drivers and my monitor I didn't find a way to do this...

even the cheapo TFT I got for my dad's computer supports 75Hz easily. So that's the refreshrate I set it to
