Slowdown on Quicktime HD Video's

by nextgengamer32 / November 16, 2008 2:23 AM PST

I often play HD video on both Windows Media Player and on Quicktime/Itunes, however my laptop plays WMV HD and AVI HD files smoothly, it does not play any MPEG-4 HD video's or HD Quicktime Mov. well, often slowing the frame-rate right down, Is there a reason for the slowdown on these files compared to WMV and AVI?Thanks

Possibly, but without knowing the specs of your system and info about the videos in question, it's impossible to say for sure. Just that different codecs require different levels of processing power to decode, and things like bitrate and motion compensation used in the encoding process can result in widely varying levels of processing power required for decoding even with the same codec.

Compare the machines. HD can require more...
