720P video playback question

will the Intel IGP (X3100) be able to hanle 720P video playback, or do i need to get the nvidia 5800G or whatever.

i have no idea if GPU has much to do with video playback, or if it is mostly CPU. the computer will be the dell m1330, 2.0ghz, 2gb ram.

thanks.

 

Yes, the X3100 integrated graphics can handle 720p video playback.

 

AFAIK, all modern IGPs handle full HD without any hitch. Also, install CoreAVC for supreme HD playback. [Windows only, mind you]

 

Download and play HD demo from http://www.nzone.com/object/nzone_hdcontent_home.html

Please note that there are no Blu-Ray or HD DVD movies that are encoded in 720p. All of them are encoded in 1080p. The link I mentioned is encoded in 1080p. So if it plays fine with your computer, you are probably OK.

 

Video Playback is more CPU dependant than GPU fyi so the cpu is really the more important thing to take into consideration.

 

You can have HD DVD and Blu Ray in 720p. Rip HD DVD and then encode it in 1080p. It's just that the native res is 1080p (which would be 1920x1080).

Encoded Res != Default Playback Res

And feel free to correct me. Above said is just my understanding of it =)

 

Considering the amount of time and space required to rip an HD DVD, I don't think most people would be interested ripping an HD DVD.

 

I surely hope you are right since my GeForce Go 7400 64MB VRAM is not officially supported to play Blu-Ray or HD. But Cyberlink and Intervideo keep pounding their heads that we need very fast video card with at least 256MB dedicated VRAM blah blah blah.

Cyberlink keep blaming my card when I complained to them that I keep getting flashing green screen when playing Blu-Ray DVD. OK, if that is the case then why WinDVD BD for VAIO plays fine while WinDVD does not officially support my card either.

 

Yeah I know. I was just saying that you can get HD DVD content @ 720p.

 

i was only interested in 720p because i don't have a 1080p television, and won't for the life-cycle of this laptop.

my deskptop computer (core 2 @ 1.86ghz, 2gb ram, integrated video) plays the demo video fine, so i should be good to go with any laptop with matching, or better specs, right?

 

FYI : I played 1080p WMV HD movies available at Microsoft’s WMV HD Content Showcase on my previous M1210 with a Go7400 (64MB dedicated VRAM).

 

I tought you needed a video card with HD video acceleration like at least a radeon x1xxx or GF 7xxx . So if you take an old mobo with an intel extreme graphics igp and put a 3.8ghz P4 in it you can run HD movies whitout problems?

 

If you want to play HD movies to your HDTV, both your TV and your video card must be HDCP compliant. If your video card has HDMI or DVI-D connector, it is probably HDCP compliant but you should ask your notebook or video card manufacturer to verify.

If your video card doesn't have HDMI or DVI-D connector, you can still connect it with regular VGA connector to your TV, but the output will not be in HD. It will be in standard DVD resolution.

If you just want to use your built in laptop screen to play HD, HDCP compliant video card is not required. As long as your video card and CPU are powerful enough, you should be OK.

 

i am looking to buy the dell m1330, and mainly just wanted to know if it could handle playing higher-resolution video files fine without the $100 nvidia graphics card since i won't be playing any games. it appears that is the case.

i assume if not already, than soon we will be downloading HD rips of movies (or purchasing them through digital download ) and i want to be able to play these with multichannel sound through hdmi to my onkyo tx sr-805 reciever which i assume is hdcp compliant.

i've been here for a day, and from what i've read i think i should be okay. am i? thanks for your help, folks.

 

Unless you wanna play bluerays or HD-DVD's (or certain specific files) it will be CPU Dependant. The best h.264 decoder is Coreavc. I couldplay any 720p files at 1440x900 and 1,6GHz (my old, now dead laptop, had a 2GHz C2D), with resources over.

 

As long as your M1330 has HDMI output, it should be OK but I don't think we are going to see downloadable HD anytime soon. A full length featured HD movie will take at least 15GB. Even with broadband connection, 15GB is still take too long to download.

 

Depends on how well it's compressed. A 720p X264 movies is typically encoded as a dvd-5 (4,4GB) and a 1080p is usully DVD-9 (8,5GB). There are exceptions of course. Many 1080p are like 11-ish GB. On a 8 Mbit connection that takes about 3 hours. 15GB is about 4-ish hours.

 

Certain codec/gpu combos can actully offload some of the work to the gpu to allow the cpu to do less work. You dont by any means NEED one of those codecs or video cards but having it will help alot if your cpu is not really fast, some 1080p stuff will really push a high toll on a laptop cpu so thats why they have it. For Nvidia its Pure Video & Pure Video HD, for ATI I forgot what they use. Its present supported in almost any recent gpu tho, they dont have it in the highest models tho like the 8800gtx and the 2900xt for the desktop because I suppose they assume if you have the type of computer that uses a top video card, you have a top cpu and dont need it.
