H264 movies are sluggish?

Hi,

When I run HD quicktime movies, it's often sluggish at 480p and always sluggish at 720p and 1080p. I thought my computer was quite up to date (without being "Da Bomb"...). Is it normal with my configuration or what? I meet the requirements for the 480p size.

Athlon XP-M @ 2.2GHz
PC3200 CAS2-2-2-5
X850 XT PE @ 600/560 (RAM/GPU)

Thanks

yup. the h.264 is a really complex codec and for example, apple's trailer site with h.264 movies states that the recomended rig for 1080 is atleast a dualcore procesor.

Hmm. 480p should be fine with your machine I'd think. 720p might be fine, but 1080p would kill it.

Go to start menu run, and type this. perfmon.msc Press the + (Add) button on the toolbar, and add some stuff like hard drive counters ("LogicalDisk") and CPU usage ("Processor Time" under "Processor"). Try and identify your bottleneck.

i have the exact same config, athlon xp 3200+, 1GB ram, X850 XT PE

480 renders smooth, 720 renders at 10-20 fps, 1080 renders at 1.5 fps

dont be surprised. We are stuck by single core date cpu. Its not your ram, and its not your video card holding you back (although a card with H264 accelleration like AVIVO for ATi or PureVideo for nVidia would help).

Time for an upgrade for me and you!

The problem is that your video card doesn't provide mpeg4 acceleration. It takes a lot of processing power to decode mp4 as you've discovered. If you really need to do it, look into getting one of the new generation cards.

The problem seems to be hardware support (or lack of when using quicktime player) not your cpu or video card. Try using nero showtime player I can play 1080(only tied X-men) not dropping frames using it and only 80-90%cpu usage. but it is scaled to fit 1600x1200 so not the full 1920 wide.
but it is night and day, when playing the 720p move 40-80% smooth as butter? quicktime 100% and dropped frames.
System= A-XP @ 2.0 with 4200ti

I downloaded and tried VLC.
720p=20% cpu usage
Try it, its free and seems to play back 1080 with no problems for me. (my older version crashed before even playing h264 so get the latest)

I also get varying results from different players and decoders. Since your ti4200 can't hardware accelerate H.264, any improvements are because of the software.

VLC is not fast for H.264.

Get K-Lite Media Codec, and use Core AVC and Haali Media Splitter. It should run smoothly.
