The Tech Specs of HD Netflix Streaming
Posted by Mark Wilson at 4:20 AM on November 20, 2008
Hats off to Netflix. Without really being prompted, they've released their HD encoding/streaming specifications for the world to see. The company revealed that they originally considered a WMV3 (Windows Media Player 9) codec running at 4000kbps and 5500kbps, but opted instead for a similar Microsoft codec, the VC1AP running between 2600kbps and 3800kbps—which should provide a better experience for those of us with lower bandwidths.
While Netflix offers 24fps movies in their native frames per second, their other content peaks at 30fps. The company researched the 60fps content found on Blu-ray discs, they realised that they'd be better off reserving that sort of quality for another era. Good call.
While it's a bit unfair to compare bitrates across codecs, Vudu's premium HDX material is still the top dog in streaming, supplying encoded rates ranging between 9Mbps and 20Mbps. Then again, most of us can't watch that footage in real time. [Netflix via CNET]

Still getting the whole "doesn't work on Macs" message on Netflix.com. Musta missed the beta thing. Any idea when they're going all out?

@NNTPgrip: I'm crossing my fingers that hulu streaming follows Netflix to Xbox. Probably won't happen, but imagine if it did. IMAGINE DAMN YOU!!!

Not sure how to do it on a 360, but on a PC it's +B to bring up the bandwidth menu

Only one problem with the Netflix streaming, where I'm at college my connection sucks. The streaming quality is horrible, the quality is based on your connection. There's no option to download some of it and download the rest while you watch, or at least not that I have found so far toying with my Xbox.

Right, I have good internet connection, 15mbps but sometimes it goes to lower quality and I have to kill IE and like 4 other things that it runs for it to determine quality again

@Killtodie: Yeah, that would be nice. I wouldn't mind waiting for good quality.
Perhaps a smart idea would be to have something like 5 movie 'slots' on your XB HD, it downloads those 5 during non-peak time, or anytime you want ... then you can play those at high quality and not have to wait.
Delete one of the 5, and it starts pulling the next one.

Finally some solid data. Good to know, considering my internet connection maxes out at 2.2 mbps and the minimum here is 2.6. Of course, that also shows the true quality of the picture - VC1 compression is also used in many Blu-Ray and HD-DVD movies, so we can compare bitrates. Blu-Ray and HD-DVD use 24+ mbps bandwidth, but at twice the overall resolution of Netflix, so a good comparison is that Blu-Ray/HD-DVD movies are 3 to 6 times better looking (depending on your internet speed) than Netflix when viewed at 720p.

Just watched the pilot of 30 Rock on my Xbox. HD (Quality 3/4) streaming was nearly instant and looked very good, maybe a notch below Dish Network's broadcast HD.
I have no complaints.

@Killtodie: You can watch in Firefox if you sign up for the Silverlight beta. You're SOL when it comes to selection of resolution, though.

I just tried Netflix HD streaming to my Xbox 360 with the new Dashboard this morning; worked like a charm. Heroes Season 1 started playing within 15 seconds and it looked great. I mean not Blue Ray great but considering... I wasn't disappointed.
I just hope their HD content expands a bit more. And like soon. Like before my 2 week trial ends. ;^P

I'd really appreciate some PS3 support. Here's hoping Sony isn't c-blocking them because of their own service.

I second the buffering request.
Netflix on the interweb browser does buffering.

There isn't any 60 fps content on Blu-ray...what are they smoking? It's almost all 24 fps, and some is 30 fps.

all I want to know is how do I find the HD movies that can be streamed? I tried several which should be HD but none of them did. Is there a search or list of the movies Netflix streaming provides in HD?

@EnochLight: Netflix is worth the monthly price. I work at a Video store and I still have Netflix because they have a better movie selection. Plus I work at Hollywood video, and we charge twice as much for the same service Netflix has (3 movies out at a time no late fees, Netflix 14.99, HWV 29.99) and you have to drive to HWV when Netflix comes to you.

@pete: Not always it can actually run up 120fps, content can be stored in many ways but it is up to the director as to how the Frame rate on the disk is displayed. BR can have 24p, 30p, 60p, or 120p but we probably won't see movies with 120p for a while at least until more 120Hz TVs arrive at a better price

@Dreamwriter: yeah BluRay can support up to 64mbps on a disk that's a lot internet streaming is like 8mbps if you have a good connection (although I read that a while ago it might be better now), and can we forget about HD-DUD its more dead than my Great Great Great Great Great Great Great...

@Ideapimp: it "works" on macs. though i was somewhat disappointed. not even talking HD. but like the normal streaming.
not so hot.
i understand the silverlight deal is a beta... but it can hardly play in a normal browser window. and full-screen is completely out of the question. *MASSIVE* dropped frames. like sometimes a still screen for 10 seconds with audio still going.
not cool.
this is with nothing else running. just firefox. (tried safari too for S&G.) and the netflix bandwidth tester deal said "high-quality" or whatever. it also nails the processor to the wall.
if i option-clicked links into a new window and made it 1/4 screen or so (640x480-ish)... then it was fine. but 1/4 screen sucked it. and processor was still at like 60% on both cores or so.
i was thinking it *might* be bandwidth related. until this morning... when the "New Xbox Experience" arrived. it worked perfectly. no glitches. no dropped frames. and conveniently on a TV too.
hopefully it gets better on the Mac. i was on a first-gen 1.8GHz Air. i would expect it to work... not an old machine in any sense. never tried on other machines. like i said... watchable. but not perfect.

@enumerator: Log into your netflix account and click on the "View Instant" (i think?). Here you can pull down a Genre menu and you will find HD listed. There is the list of all 300 HD movies and shows. There is a hand full of good ones. You just add to your Instant View Queue what you will want to watch.

@Killtodie "gave me the option to select quality":
you can manually select the quality of the videos you watch on netflix via IE (I wish it worked in firefox also, maybe someone could try the IE addon for firefox).
when you select a video in netflix and select play
1) you will see a black screen where it says "determining video quality"
2)as soon as you see the netflix RED screen, hit SHIFT+B on your keyboard and should see in the bottom right hand side of your IE browser a drop down box to manually select the quality of the video.
3) make sure your IE window is active. and hit SHIFT+B several times... but generally it should show up immediately.
