Please help.I see dropped frames with g450

[hakan2003]

hi
i have matrox g450 pci 32 mb card. when i watch dvd and also divx i see dropped frames both on monitor and tv.
maybe its not easy to feel it but i see it and if i tell someone who also watches films with me then realises this.
how can i improve my g450.

Maybe you are playing movies with different frames per second that the standard you are using to output them to the TV. Maybe you play Pal movies on NTSC or the other way around. Try and alter the output standard of the TV out signal, if your TV supports this...

I think it's not really the cards fault, what kind of cpu do you use? At least the G400 didn't have neither motion compensation nor idct, so the only video accelerating feature is the hardware overlay. Means your processor has to do this job.

PS: maybe you should add the country you live in to your parhelia-post.

Usually divx files aren't interlaced, so the pal/ntsc formats may not cause problems. Or am I wrong?

[Peter Aragon]

sometimes it helps to have the framerate from the divx equal to the output standard. For american DivX movies I get better results on the Parhelia when I use NTSC. (NTSC=30fps, PAL=25)

[dZeus]

then again, movies are 24fps not 30.
So set it to PAL and use ReClock to make it run at 25fps

It all depends on how it was encoded.

[dZeus]

what do you mean? wether the person who transcoded was too stupid to do IVTC or not?

[Ribbit]

In a nutshell, yes.

And with some DVDs it's difficult or impossible to do IVTC, e.g. they've converted the material to 30fps and then done some postprocessing on it.

Or of course, the source may not necessarily be a movie.

[dZeus]

true, in that case a hybrid framerate medium (like with software pulldown flags) would be optimal, like DVD or SVCD
Haven't checked wether it's easy to transcode hybrid material without needing to force hardware pulldown on the progressive source, or to force IVTC on 30fps source. Appearantly CCE has detection for pulldown and can insert field repeat flags

i have P4 2ghz computer.i have a tv that supports both ntsc and pal system i have tired them both and also dvd playback is not good as the divx.vcd is good any mpeg1 encoded stream is ok.asf and wmv is also great but mpeg2.(i had try to watch a mpeg2 transport stream (sattelite recording file)it was a slide show. )).i hope parhelia doesnt have this kind of slowdowns and frame drops.
thanks for everbody that has send a post for help.u are all great
