renderer is too slow

[dimitrius]

I have just encoded LOTR-FOTR, I encoded it at about 1500kb/s and at 98% of original resolution. (to be placed into an ogm so that with the audio it would take up 2100MB). It is encoded with XVID 1 and audio is vorbis.

Whenever I play it, the video has a lower frame rate. The framerate should be 25fps but I'm only getting about 19. I traced this to the renderer.

Now, I've tried different renderers (all the options offered by MPC) and all of them can only give me about 19fps. my CPU usage during the playback is about 30% and plenty of RAM left free. My guess is that the problem is more graphics card related and is caused by having a larger resolution (in the encoded file). My graphics card is Geforce 2 GTS (yeah, it's old) but I've never had any problems before and I have used larger resolutions for some DV stuff.

Does any one know how to fix this?

Do you use an older ffdshow build to decode - one which had problems if you used 'packed bitstream'?
Did you install latest drivers for your gfx card?
Additionally did you check that your files dont have such a low frame-rate?

No
Yes
Yes

don't use ffdshow, don't use packed bitstream, NVIDIA 56.72, 25.000 fps

I think it may be in avisynth script tht you have used for encoding. Could you post it?

PS: Is all XviD 1.0 playback smilar?

:o

I feel so stupid...

I left Forced FILM on in DVD2AVI from something I did earlier.

Now that I have to re-do all this stuff I might as well get on with the times and use DGmpgDec.

If anyone is still interested in the script:

LoadPlugin("D:\Program Files\Gordian Knot\DGDecode.dll")
LoadPlugin("D:\Program Files\Gordian Knot\undot.dll")
mpeg2source("F:\to be encoded\Lord of the Rings - The Feloship of the Ring\Lord of the Rings - The Feloship of the Ring.d2v", idct=6)
crop(0,74,720,426)
BicubicResize(704,288,0,0.5)
Undot()

nothing special...
