Hi
I have HP Media Centre PC with intels duo core processor, 2 GB RAM and 320 GB HD. I would like video encoding to be faster. If I need to buy a graphic card, what parameter should I look for to make video encoding faster( make video file fro VSP). Presently I have Videostudio 10 plus.
Thank you

Hi Vasan,
the video card will not have any effect on video encoding speed. For video editing, only a low end video card is needed, with no advantage to be had from faster cards.
Dual core processors, especially Intel Core 2 Duo do very well at encoding.
The amount of RAM makes very little difference to encoding speed.
In order to squeeze every last bit of encoding speed out of your pc, you might consider setting up a video editing optimised hardware profile - search this forum for extensive posts on the subject. Windows by default runs many services and processes which are not needed much of the time, and consume resources. By limiting the number of running services, you can get a bit more performance out of your pc. It's likely that Media Centre edition has even more services running than XP Home or Pro.
Your dual core setup should be fairly quick, however. My old Pentium 4 2.8 pc will encode avi to mpeg2 in just about 150% of the video running time - or 20 frames/second if you like. Your pc should be significantly faster.
Good luck!

Yes, Vasan, I agree with 2Dogs. Your question is a bit like asking 'how long is a piece of string'.
It really depends on how long your computer takes now to encode, and what your expectations are.
Video encoding is inherently a slow process. I have what is now an 'old' P4 3.0 GHz processor with hyperthreading. Depending on how complex my project editing is, how many complex transitions I have inserted, how many titles, background music etc I have added, my computer will take anywhere between 1.1 to 1.5 times real time to encode from DV/AVI to mpeg-2. In other words, if my project runs for an hour, then it will take between around 1 hour 6 minutes to 1 hour 30 minutes to encode it.
And I think that is relatively fast. Some people with older computers still, will take up to 3 or even 4 times as long as the project to encode.
If your computer encodes faster than real time, then that will be good. But if you are expecting to transcode a 1 hour project from DV to mpeg-2 in only a handful of minutes, your expectations are too high IMHO.
