How do you play HD videos?

For example, 1920 x 1080 resolution. It sometimes play stuck a bit, or cannot play at all.

 

Another point is maybe your processor if your machine is an old one.
Do you play it from a NAS or USB drive? Sometimes that is too slow and you should copy such movies to your local drive.
SSD shouldn't be needed, a HDD should be alright.

 

Is it graphic cards or processor? Mine is old specs, 2 GHz, NVIDIA Geforce 8400M GS. I play it from hard drive usually. Or should I just convert the movie lower resolution, since the movie is only 6 minutes.

 

I never had any problems playing video because of my graphic card. Also all the people I know. But CPU is crucial. At least for HD movies. That's why some e.g. Intel Atom can't play HD movies.

 

Funny, I thought it was the other way around. Sure sounds like it would be the GPU....

Yeah, okay, if your CPU is weak it is also possible that the GPU does the job. If it supports the encoding...

 

Well, if you play raw from a bluray or something it'll probably decode off most modern GPU's, if you play it from a file that depends on what video codec the movie is encoded in(I think h.264 is supported by most but probably not x.264(compressed h.264)) the GPU supports decoding.
Another thing worth noting is that 10bit which is becoming a big thing(or well it has been for a while now) within Anime fansubbing is virtually unsopported on anything but high end video industry graphic cards(which costs a whole lot more than your average gaming graphics card) so if it's encoded in 10bit your GPU will be of no use at all.

Another explanation for your issue could possibly be due to disc overloading, HD content has a fairly high bitrate so if you're doing anything else in the background(such as torrents etc.) that could cause your disc to become overloaded and when you run out of buffered video it'll start to stutter.

 

his specs are definitely not enough for a raw Blu-ray

if you want to check if your cpu is sufficient play the video and make sure you have task manager running
while the video is running check in task manager if your video player software is reaching 100% cpu
if so your cpu is to slow but i suspect it is your video card because that's a pretty old video card

are we talking about a pc or a laptop?

 

To render videos I would say the most important part is your GPU (Graphics Card). Try using KMPlayer and try all their video renderers, check if one of them suit your needs.

 

i am using I7 with win7 64 bit + k-lite play back 1080P 20-30pixel is ok. 2046P 50m pixel will slow motion

 

So what should I do, to play HD videos?

 

What is your machine's specs?

My laptop is quite outdated by today's standard - i7 2xxxQM, GT 540M, 6GB RAM.
But I notice that only when memory is low, HD video playback will be stuttered or even stuck.

 

And, make sure the hard drive is not full
