Hi I want to know if graphic card will helps to smoothly edit video? I am not sure which one is best. Does I need to install new graphic card in my computer?

The graphics card itself is not involved in processing or editing. All of the work is done by the CPU.

A better video card will not automatically improve your video quality, but a good video card with a good well-adjusted monitor can help you to see what you are doing.

Computer video (VGA and SVGA) is different from NTSC/PAL video, so the colors will usually show-up differently on the computer... This can make it very difficult if you are trying to adjust color. So, a video card with composite video out, connected to a TV ( NTSC or PAL) monitor, can be useful. (Professionals use calibrated NTSC/PAL monitors.)

Oh really about my monitor problem? My monitor is very good from Sonicview.
When I edited my video done then I clicled download the files and it load very slowly because too much effects. Is it from my monitor? or my computer need improve? My computer is HP Pavillion AMD 4200 X2 Dual core with Windows Vista upgrade. 2GB RAM and 250GV hard drive. I am not sure if i have VGA.

Not sure what you mean by when you downloaded the files it as very slow, can you expand on this for us.

Your pc has a pci express slot, so get one of these cards, they are up to 7x faster than AGp cards.

N-Vidia have better drivers than ATi for Vista at the moment.

Get one with at least 256mb of ram, but 512mb is better.

You'll then be able to use the GPU graphics processor unit rather than the CPU in video editing apps which have been desinged to do this.

Sorry
When I edited my video done then click Share then click Create Video File.

I am not sure if i have VGA.

All computers have some variation of VGA (and sometimes a digital-monitor connector).

If you also have a composite video output (NTSC or PAL) it will be a yellow 'RCA' jack exactly like the "video out" on your DVD player or VCR. From the specs, it appears that your computer does not have this... Most computers don't. However, some of the graphics cards on your link say "TV-out".

You'll then be able to use the GPU graphics processor unit rather than the CPU in video editing apps which have been desinged to do this.

Skier, Is Video Studio "designed to do this"?

In any case, that won't affect the quality, it will only help with the speed. (It's all just "number crunching" as far as the computer is concerned.)

When you are working in real-time (i.e. generating graphics for a video game), then speed and quality are related. A faster graphics card can generate better graphics in the limited time allowed.

The same is true with real-time capture... The computer must keep-up with the streaming video!

I have Hauppauge! WinTV recording. I am not talking aobut TV tuner. I am talking about Videostudio 10. I edited video on Videostudio and it was done. I click "Shaire" then "Create Video File" to save it during it run so slowly. Depend on how much I put effect on it. Sometime I add 4 overlayss etc... How should I improve my computer and fast for create video file.
Is it clearly?

HP Service say:
To edit videos, there will be no specific graphics cards available.
However, if you wish to upgrade the video card then I recommend you to
visit the nearest reseller to purchase the compatible video card.
However, upgrading the video card in your PC requires upgradation of
Power supply. As some high end graphics card requires 300w to 400w power
supply requirements.

They say need 300W to 400W Power Supply, What do you think?

How long does it take you to render a 1 hour program?

Your computer is already quite fast and it's dual-core, so I don't think there's anything you can do to make it a lot faster. For example, I don't think it's possible to cut your render-time in half.... Maybe you can get a 10% - 30% improvement by trying various things... But, I'm just making wild guesses...

You might be able to speed-up rendering a bit by adding a 2nd hard drive. Put all of your source videos on one drive, and render the output to the 2nd drive. That way, one drive can read at the same time the other drive is writing.

I'm not sure if a better graphics card will speed things up. (skier-hughes says it might.)

Also, if you select single-pass encoding rather than two-pass encoding, this will speed-up encoding at the cost of lower-quality. (At high bitrates, the qualty loss might not be noticable.) There is also a "quality-silider" that you can use to make a trade-off between encoding-speed and quality. (I've forgotten exactly where that window is, and I don't have Video Studio on this machine.)

I made a movie for 23 minutes. It is 113MB. I edited 4 overlays, videos, some pictures, and more Transition from Boris FX. When I was done it then click share then Creater Video File for .wmv and it was ruunning about 40 minutes. Very Slowly.

You may be interested in this reply I recently made in the Hauppauge User Form

The original post in that forum was:

I'm getting choppy video (i.e. slows down for a second and then catches up, repeatedly). This only occurs while watching TV live from the card (either in MythTV or mplayer /dev/video).
If I record the the stream it comes out perfect. I'm not getting any buffer problems when looking at the messages file with ivtv_debug=1 set. Any help would be greatly appreciated.

Thanks, Mike
My setup is :
AMD 3000+ Sempron
512MB ram
PVR-350

Recently upgraded to a HVR1300 and got the same problem mentioned here - choppy live TV but perfect recorded TV. I even took the HVR1300 back to the shop and had it changed. The new card did the same and so I placed the HVR into my second computer and it worked perfectly.

Knowing it wasn't the TV card I looked to see what else it could be. Eventually I discovered the HVR1300 required either an AGP Graphics card or a PCI-E Graphics card. Mine is a PCI (Without the E) something simple that I overlooked as I had been using the PVR350 for quite some time.

A new video card will only improve playback in real time of video content on your PC. Rendering doesn't use much video.
If using Powerdvd or winddvd to playback your videos and they are playing good then you probably don't need a new video card.
How do regular Dvd's playback?
You would probably need a new video card to playback HighDefinition Video.

What your doing takes a long time to render because your source videos are mpeg with overlays, pictures and whatever else you've added.
Creating Windows WMV videos is very time consuming.

Let it render overnight and see it the render even completes without any problems. Using many mpeg's as source videos on main & overlay tracks is hard. Usually this is done with the videos source content being in the DV format.

40 mins for a 23 min file to wmv doesn't seem outragous to me. Not direct from the timeline.

VS doesn't have any mention (that I can see) of using GPU in VS10, whether it comes along with V11 we'll have to see.
