Video Compression - Nexus One General

Hi, A big problem I had with the iPhone was the video compression when streaming video in applications such as youtube.
I thought there would be less or no compression on the Nexus One since the higher resolution makes the video look even more appalling and I can't even make out what's happening.
I was wondering whether there was an option or an app which lets me disable this or lessen the compression so that I can actually make out what's happening in a video rather than staring intently at blocks and smudges. (forgive me for hypocritically pointing out the irony that that's what we do: [pixels and colours])

once you choose a video in youtube press Menu > watch in high quality. and prepare to be amazed.

Yeah the HQ videos look amazing, i havent tried other sites yet. The video adobe put out of flash running on Android looked pretty damn good too, cant wait for that.

is there any way to get it by default to always go to high quality

not that I know of.

After i set it to HQ its played all the videos in that format as far as i can tell, obviously it depends on the quality of the video the person uploaded

Thanks for that, the videos look amazing!
But what about things like the BBC Iplayer app, and images on the web?

browser images are not compressed at all. I dont know about iplayer i never tried it.

The bitrate of a given video stream in a given app has next to nothing to do with the native resolution of the screen you display it on.
Specifically, most mobile video streaming app will ask for a low bitrate (highly compressed, grungy looking) stream when they detect that the device in not on wi-fi and will request a higher bitrate stream when on wi-fi, if you are lucky (I.E. in the android youtube app) they will let you override this automatic choice.
I.E. video quality is a function of the source streams available, the app requesting/displaying the stream and the bandwidth available on the device's network connection.
Only _after_ all of that is it possible for the screen to make much difference (and they generally don't).

Hmm, this sucks. According to my brother all UK networks compress images and videos (presumably so they don't have to upgrade their basestations/backhaul anytime soon ¬¬), with the possible exception of Three UK as they have the largest bandwidth available in the UK.
I guess there's no way around that, unless there's some sort of proxy or something?

Thats right Three UK doesn't as i get same quality of the video as on WiFi.

You do know that the HD2 in this phone's moniker doesn't mean that it actually decodes HD video?

Get Coreplayer, you can choose the format you want for youtube videos when browsing in it.
Coreplayer works!
So what exactly is "HIGH QUALITY" option in the Youtube menu then? What resolution would that fall under if it's not high def?

Likely 480p or some derivative of it for bandwidth reasons.
Before Youtube made the resolution-selector available, HQ was defined as fmt=18, which I believe was 480x360 or something

HDMI out resolution

Hello,
Has anyone tried using the HDMI feature? I just received my cable yesterday and was able to view anything in my gallery and youtube. The only thing that bothered me is that everything was output in 480p. (I had youtube set to HQ and it made no difference)
Does anyone know if the phone can output at a higher resolution?

hmmm... well i wish i could help ya man, i dont have a cable yet
but hopefully someone smarter than I that has a cable will be able to figure this out
I doubt youtube even HQ is streaming in 1080p
EDIT: In fact, it'd be my guess the max output resolution is probly 720p (considering it can capture in 720p)
his gallery should be higher rez though. i doubt thsi phone has the power to play 720p compressed.
The max resolution on the camera's video capture is 1280x720, which is 720p. So I doubt the phone will output anything higher (like 1080p/i). In fact, I saw one reviewer that stated that he "thought" the phone *only* outputs 720p, upconverting any video to that resolution. But I don't think that has been verified. What I *can* verify is that video shot with the camera at 720p and shown on an HDTV shows EXTREME compression artifacts to the point that a lower resolution will probably give better results (although you will not get the 16:9 aspect ratio).
What about regular HD movies in 1080p/i that are saved onto your sd card. How did those do on your hdtv. Did they come out choppy or compressed at all? I'm waiting to get my hdmi cable to test it out myself.

Actually the specs never say 1080p, they say 720p. And from what i've seen that's only when outputting pics and videos form the gallery player.
We want to get netflix on our Evos and do the output to our TV's.
I wonder how the outout will look on that?

I remember seeing a post on engadget a couple weeks back with a video demoing the ability to play youtube hq through HDMI. they were watching a video that had paint splashing around in slow motion. It looked great! Last night I tried to watch a couple of youtube videos that were hq quality with the hdmi cable plugged into my tv and they looked horrible. I thought it might be a setting on the phone, but I could not find one.

I have the same problem with youtube. It seems that it does not use 720p, even in "HD", it seems the "HD" is actually 480p (the EVO screen resolution). Another problem with youtube on EVO (as opposed to TP2) is that unless you click "HD" there is no way to stretch the video to full screen, even when viewed on the EVO screen. This is one of the most unfortunate things I've found when trying to impress my iPhone loving friends. On the TP2, youtube was surprisingly excellent, it filled the entire screen and looked fantastic (without an "HD" option) the EVO seems to have actually taken a step back (albeit a small step) in that department.
While using the HDMI cable to my TV, it will output 720p videos (taken with the phone camera or made with handbreak.) However, it will not scale anything up. So if you create a video at the 800x480 EVO screen resolution, it will display in the center of your TV (not fill the entire screen.) I've not yet tried 1080p, considering the 1600mbs (realistic) encoding limitation, I don't think 1080p will be a good idea even if it does work, just stick with 720p.
So 720P movies and stuff will work just fine?
Can it display the UI of the device and other apps...or only multimedia content?

This x 1,000.
I'm still not sure if I'm getting an EVO or Streak, but both have HDMI, and either way, I want to be able to hook my device up to a monitor and use it in the same fashion that I would my netbook (i.e. light web browsing, very light office/doc work, maybe some light games).
Basically, I'm looking to get rid of my netbook and replace it with my new smartphone...but I have to break out to a larger display from time to time.

How to force high res youtube on 3G

I wanted to see if anyone has been able to have by default high res youtube playback on 3g connection. I know that the youtube app will play higher resolution over wifi but on my old htc devices I was able to stream high definition over 3g.
I'm also intersted in this.

Bump again for this topic. I'm surprised it's not talked about more.
I just came from a Samsung Captivate and it has an option to run video in HD. It took a little longer to load the film, but was well worth it!

Yes, just people with HTC devices are able to watch HQ videos...
That sucks! I would have just gotten the HTC Surround if it didn't look so cheap and have such bad reviews.
We can only hope that either MS or a developer can come up with some software to fix this... as I wouldn't see this as being a hardware issue.
Buy a "RealTube" app, works fine on any handset.

720p recording on the HD2 with the DFT WP7 ROM

I haven't actually installed the ROM myself yet on my HD2 (kinda happy at the moment with MDJ's 2.3 Gingerbread NAND ROM for now), and I know that the DFT WP7 ROM now finally enables true 720p (1280x720) video recording.
Can someone do a test recording of that functionality and post the video sample someplace so I can see what kind of quality it offers? Just a 30 second clip would be great, perhaps something shot out of a window in daylight, whatever, doesn't matter. Just want to see how the quality and performance of the video appears.
Drop a link here from wherever, maybe post the clip to MegaUpload or something (not YouTube, please, as they might re-encode it to another format/settings). I'm looking for a native recorded clip on the HD2 using the DFT WP7 ROM at 720p settings, that's all.
Thanks...
I know you mentioned no youtube.. but i don't know other way.. and megaupload has an error when I tried it.. but just to give you an idea. here is youtube link for 720p with HD2..
http://www.youtube.com/watch?v=u5cv6bQ9FgA
Is it just me or is there a lot of noise interference in the background?
If you Zip or RAR the clip, MegaUpload or even MediaFire (faster) would accept it, but anything with the native .mp4 extension can be problematic as those sites try to treat the file as a streaming video.
I downloaded the YouTube one you posted, myowin, thanks. If anyone else has samples, go for it, I'm just trying to see what the HD2 is truly capable of so a variety of samples would be awesome to check out. This one posted above looks as expected - not "professional" level quality but then again we are talkin' about a smartphone with a tiny optical sensor in it.
It ain't perfect but at least finally we can do true 720p video recording on our HD2.
Always knew the hardware was capable...
As far as noise, the video itself looks as expected as I mentioned, and for audio noise, the mic is simply picking up whatever it can. It's pretty amazing when you do a recording in a room that you think is absolutely quiet and realize when you play the video back that there's a ton of background noise in it. Our subconscious minds filter out a lot of that background noise because it's always there, but when you listen to a recording, the brain knows it's not listening to the background noise anymore - instead, it's a recording of it and all that background crap just comes through loud and clear.

Yah, it is, and thanks for the proper upload. The YouTube version was re-encoded as I suspected and chopped - it's only 6.32MB and they cut the average bitrate down to only 2795 Kbps whereas the original video you just uploaded to MediaFire is 7911 Kbps for the average bitrate and it looks better because of it (while remaining the original 17.7MB in size also).
So I'm guessing the "average" bitrate done on the HD2 with WP7 is about 8 Mbps 720p and that's more than acceptable.
removed.

I think he's just a heavy breather lol
at first, I was gonna say there's no 720p when I noticed my vids are all 480p
and after reading more topics, I found out that I must use English (US) not UK to enable 720p =.=
I thought WP7 camera is no better than iphone camera at first, but the features are actually hidden in US English versions...
I don't get it why they hide it there....
Btw, 720p is now 100% working and quality is brilliant!!!
Any hackers gonna port it to Android??
But 480p got a faster framerate than 720p

Hi, i have a questin about 720p playback right on the phone.
i cant playback the recorded files in 720p on the phone.
it will only play files in lower resolution.
is this normal ?
I wondered why it only records with low settings xD It's a little bit tricky but ok ^^
No, that isn't beacuse of him. A couple of days ago I tried capturing a 720p video at work...After that I noticed that there was a much more louder than this guy's noise in the background and figured it out why...I was about 1meter from a PC and the noise was coming from it's fans. I don't know if this is good or bad but 720p for real ! )
°
aaam is it possible to play the recorded 720p files on the phone ?
i have a black screen and only here sound when i try to playback 720p recorded video.
I just made a video, though I don't have that noise in the background.

[Q] iphone 4 to SGN burning questions.....Thanks in Advance!

I just got my Note in the mail from Clove UK. And everything is great so far, and I dunno if this is and Android thing (This is my first Android device) or a Samsung thing. When I play videos from You Tube or videos that I encoded the blacks are heavily pixelated. (Not sure if that's a word). Am I doing something wrong? What program and/or setting is the best to get rid of that black pixel issue? The test video of the jelly fish works great. Noob questions I know! Thank in advance again for your help.
My guess is that its not directly your fault.
There are several aspects to think of here:
- It may be that artefacts (caused by video encoded in low bitrate) are more noticable on a screen like that of the galaxy note than others.
- It may be that youtube just delivers you the low quality version of the video.
- The video on youtube may be in bad quality to begin with, try other youtube videos and see if it happens only on a few ones or many.
- Note: I see now you already tried the video, so that is probably not a cause. (Your screen itself may have some flaws. Check on that for instance by using a screen test tool like "Screen Test" or playing the video already supplied with the Note (Open the standard video player app that comes with it and select "lightness & slimmess"))
When it comes to watching youtube on a mobile device I recommend (if you have a mobile data connection with enough bandwidth, such as good umts or hsdpa or Wifi) to enable high quality in the youtube app (whenever possible, use the youtube app, and do not play it in the browser).
To do this hit the options button in the youtube app, select settings and enable the first option to enable high mobile quality.
Secondly many videos will allow you to switch between lower and higher quality with the HD button on the upper left (visible at the start or when you tap the screen while palaying) - if you enable high mobile quality this should be turned on to high quality by default.
When it comes to youtube thats probably all you can do to improve quality.
When it comes to playing videos in general (excluding youtube) the standard player can manage most formats. However if you have trouble with some videos you may want to give Dice player a try!
Hope this helps!
Ok thanks, I will def try that!
I belive this is coursed by the hight res/density of the Note screen and low quality of the video in YouTube app, I think the highest quality of video in the YouTube app is only 480P.
I also noticed this problem while streaming old TV shows from PLEX to my Note, this is less noticeable with my Tab 10.1 with the same resolution but its screen is about 4 times larger.
You could use the stock or most aftermarket browser and watch 720P YouTube using Flash on normal YouTube site.
simple solution is to not use the app and just use a browser. ive had no issues watching 720p videos in youtube on the browser.

I've noticed this too with the You Tube app. The blacks sometimes are blocky. A good example is the Avatar 1080p trailer, especially around 15 seconds mark: http://www.youtube.com/watch?v=_i2RCBa3l-g
If I view the same clip on You Tube via a browser (720p settings) it looks better, but the browser is a fiddly substitute for the app on a phone. It does seem to be mostly a bitrate limitation though, so maybe Google or a.n. other hacker needs to modify "HD" on their app to mean a higher bitrate, now we're defining 1280x800 as a mobile screen resolution .
[edit]
Actually, if I watch that Avatar clip in the browser with a playback quality set to 240p or 360p it obviously looks pixelated, but doesn't show the blockiness that's in the You Tube app stream. Looks like the app either is handling the stream differently (badly) or the stream itself is different to that which is sent to the flash plugin in the browser. Wonder if Google is using a different codec for their app. WebM maybe?
