View Full Version : Optimizing VLC

2nd November 2005, 10:45 PM

Id like to know how to best speed up VLC so I can play most of my avi files on my iMac G3 400. It plays them but drops lots of frames.

This might sound like a completely STUPID idea, but is it even possible to slightly overclock the CPU in this iMac? Not that it would be a great idea, seems to get a little hot.

Also im mirroring the display onto my LCD TV, so how can I set VLC to streach the image upwards so it is in the proper aspect on my 16:9 TV?

I'd steer clear of overclocking but FWIW you can fix the LCD problem by choosing "Overscan" from the Displays item in System Preferences. (I'm assuming that you're using S-video or composite video to connect the display.)

Im using VGA out on the iMac, its a DV SE model.

I basically want just the proper aspect ratio for playback and disabling things that slow VLC down like post processing etc.

That computer just plain won't play movies at an adequate frame rate unless they're vanilla AVIs. Over-clocking wouldn't help either; it's mostly a video card thing.

As for VLC stretching the image, does Preferences > Video > Output module > macosx > Stretch Aspect Ratio work?

Overclocking is a soldering job - not a simple task.

Haven't got a Mac in front of me at present, but to into VLC preferences, click on 'advanced' and check anything that says 'hurry up'
