So the NExus 7 has a resolution of 1200x800, which is very close to the native 720p resolution size.
My question is, when streaming a 1080p video file on the nexus 7, will it look any better than a video size with a resolution of 1200x800 or 720p?
Wouldn't it be better to convert the resolution of 1080p videos to 1200x800 so reduce file size yet reduce absolutely no quality?
During this video http://www.youtube.com/watch?v=sOqn62m49S0#t=11m55s the guy plays a 720p file and 1080p file, they are streamed from a usb drive but how does the performance differ on the two even though they are playing on the nexus 7 screen, so are being outputted at 1200x800?
Another question I have is can I stream a 1080p video file using micro HDMI cable from the Nexus7 to a 1080p capable TV? Will the Nexus 7 GPU output 1080p on the TV full screen?
Help is very much appreciated!

The nexus 7 doesn't have a micro hdmi. So that's not gonna work. Only a mini USB but you can use an otg (on the go) cable to attach a flashdrive with movies you would like to watch. 1080P and 720P are compressed differently. 1080P is a much heavier format so if you really want the full 1080P experience your gonna have to stream the full size video which can be around 10gb. By reducing a 1080P video you can stream it easier and it will still be HD but quality will be less. 1080P is always going to look better than 720P because it is compressed so many times so the picture is literally made tighter increasing clarity. Lets say you took a 5mp picture and a 8mp picture and looked at them on the nexus 7 when you look closely at the pictures you can see the clarity difference between the 5 and 8 MP. Compression is what makes the biggest difference. You are cramming more and more information into a tiny place. So 1080P will look nicer on the nexus 7 but so will 720 but the details will be clearer on 1080P even though the nexus 7 outputs in a lesser resolution. But the difference will be harder to see on a smaller screen but much more noticeable in a bigger screen. But streaming a 1080P can be choppy because eventhough they are being displayed at the same resolution they are being input differently. Sorry for the long explanation

Ok so is it possible to make a 1080p file reduced in resolution but not as compressed? So it still includes the detail you are talking about?
I thought that the pixel resolution was the main quality aspect of a video being outputted.
For the micro usb, i meant a micro usb to hdmi cable you can buy? http://www.amazon.co.uk/Kitvision-Micro-HDMI-Adapter-Cable/dp/B005TF2F2W

Mhl is not currently supported on the nexus 7. So no micro USB to hdmi. 1080 P is the resolution so if your going to reduce that then it wouldn't be 1080P. It might be 1080 I which is less but 720 P and 1080 I equal out to the same resolution. Honestly 720P is going to give you plenty of clarity and I wouldn't stress about 1080 P. Unless you have 1080 P movies downloaded I wouldn't worry about it.

Zippox your making a mistake. You are confusing scaling and compression. Compression determines files size, clarity (less pixels). Scaling which is done by your set top box, DVD/blu-ray player, computer, smart phone, tablet just makes it fit to screen or what ever size it needs to be. Will 1080p look better on nexus then a 720p that's a yes/no answer. It will depend on how much each file was compressed. Generally a 1080p file is compressed much less then a 720p. Why? Cause its resolution is too huge. Which means compression (blocks aka pixels, seeing weird shadow/dark areas move, blurry images) can be easily seen if its not done right. If you set a 1080p file and 720p file and compress them the same bit rate as the 1080 and view it on a 7" native 720p screen you will not notice a difference. Why one will be scaled down and the other will not be scaled at all. Clarity will be equal at that point. Now once that 720p file has to scale up then its defects will be shown regardless of actual screen size. And trust me you will never stream a 10gb file. You can download a 10gb file but you will never stream that. Those stream sites actually offer two completely different files. The streaming file is much more compressed. Why server load, then actual internet speeds. That would have too much strain on the server. This is why streaming is not an alternative to actually owning the file. And the digital download is not as good as its blu-ray medium.
But scaling and compression are not the same. And you were getting them confused. There is no point in a 1080p file for the nexus 7. Unless you have it 1" from your face and straining your eyes you will not see the difference if its encoded (compressed) properly. 1080p scaled down to 1280x720 will look just how its supposed to at 1920x1080 you just need to be closer to the screen. But then make that fit on 7" and 720p scaled down. That's just waisting space on the nexus7. a 30 minute anime file at 720p is generally 250-350mb. Its 1080p counterpart is usually 700mb. And it will look the same on your tablet. The only difference will be based on source material. TV capture vs blu-ray rip.
Then there is compressors. H264 8bit, h264 10 bit, divx, xvid, wmv, mpeg2. This will also define how the video looks. H264 10bit is the current best compressor. You can have a h264 10bit compressed lower (in megabytes) then h264 8bit and it will look just as good as its higher filer size h264 8bit. But naturally they will compress it less to completely blow h264 8bit out the water.
None of this has anything to do with scaling. Scaling down you see less but still looks very clean, and clear. Scaling up makes for a sloppy mess. And lesser you compress the less of a mess it will look but it will not ever look as good as native or less. And scaling of actual screen you should never see a difference as long as resolution of screen isn't touch.
There are two meanings for scaling and 1 for compression. Scaling resolution, scaling actual TV. Compression is only for file size which determines the actual quality. Overly compress it will look horrible. There is no under compress. Scale up from files resolution will degrade any image.

N7's resolution is 1280*800 and you should use 720p video as 1080p would just be a waste of space.

Maybe I should have made it clearer. Compression and scaling are different yes. Compression is taking a file size that is large and compressing it into a smaller size to fit. So taking a 1080P picture and watching it on the nexus 7 will look great. SCALING that 1080P picture to fit a 720P picture will change its resolution so that a 1920x1080 will fit on a 1280x720 size screen. Clarity will always go down regardless. Unless you are upstaging in which case it depends on your source. ENCODING is taking that same picture and converting into a different codec say xvid to avi. How you encode that picture (bitrate, codec,resolution) will determine the output quality. So bottom line 1080P will look better than 720P. But that's why I said don't sweat it on the nexus 7 because the difference will be minor. On a last note I stream Blu-ray rips at 10gb-15gb from my PC to my xbox all the time but unless your internet has an extremely high upload you will get choppy playback. Again sorry if I wasn't clear.

Do you typically record 720p or 1080p video? I use 720p because the files are smaller and I own a 720p tv. I wondered if 720p might offer better quality in low light conditions because it can average over more pixels in the sensor?
Also if the phone cpu is working too hard at 1080p does it reduce quality by upping compression and increasing lossyness?
Or is 1080p substantially better choice with the only downside being bigger files?
Generally I've found video IQ to be some what independent of resolution (on other devices) because compression generally goes up with resolution negating a lot of the benefits.
Thoughts?
Im using 720p cos it seems to me more clear and more smooth playing...plus less zoom.....

You are right, due to the binning would select the less noisier pixels and thus, the 720p video quality [except for resolution ofc ] would be much better.
I prefer 720p mode, only because of the field of view, it's just too narrow angle in 1080 mode.
Suppose it could come in handy if wanting to shoot something more distant but for indoor work it's not wide enough.
Sent from my GT-I9100 using XDA App
For me only 720p, because in 1080p I get a thin, purple line over the image that's also recorded into the vid, making my 1080 mode effectively broken.
I always thought 1080 as higher quality than 720p. Maybe for mobile this is different? Any source or test for this?
I'll try and shoot some comparison footage tomorrow.
Not sure if YouTube's compression will make the difference impossible to tell though.

This is a totally different matter. Yes, 1080 pixels are "higher" than 720, obviously . But there are other factors also on our device.
I just record in 720p. Never really compared the two, but I don't need 1080p usually, so I' don't need those huge files either.
Good discussion on here, guess I'll have to switch to 720p now on.
I tried recording an apple in the 2 modes and to my surprise the 720p mode is indeed much clearer and wider then 1080p.
Go for 720p
I prefer 720 p... for my the quality is enought and the size of the videos is so better.

Can we discuss what video formats you use for dvd rips and settings . What works what doesnt. App you use and on what os.
Me personally i make 720p mp4 videos using mpeg streamclip on my mac. I always hear ppl talking about making 1080p mkv files or whatever does the quality even matter on our none hd screens ?? Arnt dvds only 480 or 720p any how. Anyone here rip bluerays .

Resolution:
DVDs are 480p max. If you encode to higher res, all you're doing is stretching the video for no purpose.
Stretching the res just makes the end product bigger with no quality gain, and your player or device
will stretch the video anyway.
Blurays are 1080p. The scale (e.g. 720p size reduction) and quality you use are dependent on what you
intend to play the videos on. 720p is perfect for the Galaxy Note 10.1 with its 800p screen
Suggested format:
The best video codec: h264
The best audio codec: aac
The best container: mkv (for multiple audio and subs) or mp4 (subs as well as more than two audio streams a bit troublesome)
My preference (h264 video +aac audio) in mkv.
As a rough guide:
A practical DVD rip = ~1.3-1.7 GB (~1500 kbps @480p)
A decent BluRay rip would be ~2.7 GB (~2500 kbps @720p)
A fairly transparent BluRay rip ~5 GB (~4000 kbps @720p)
Free or Commercial:
Depending on how much control you want over quality, as well as ease of use, I'd say go with a commercial solution (WinAVI is quite good).
Otherwise free solutions are quite good (e.g. RipBot264, StaxRip, Handbrake) but you will need to decrypt your purchased discs to your hard drives.
I almost exclusively watch 1080p MKV files on my Note 10.1. At first the audio had trouble staying synced with hardware decoding on every player I tried. Luckily VLC recently fixed that somehow with their Android app. I think MKV is good if you have multiple audio or subtitle tracks. Logically I know I shouldn't see a difference in quality between 720p & 1080p on this tablet, but I do. Think it has something to do with how it's scaled.

The 1080p could probably show better. Though the difference should be negligible.
If the video has black bars, these may be cropped in encoding. Which means the 1080p video is closer to 900p.
Encoding a cropped video to 720p may actually be closer to 544p (i.e. 1280x544p) to maintain the aspect ratio (so the video doesn't look "tall").
If the audio stream is 5.1 DTS audio, you're gonna probably have stuttering due to processing the larger audio file.
2 Channel (stereo) audio is all you need for the Note 10.1
Thanks guys so making my dvd rips 720p isnt doing anything but making a bigger file eh. Dont think mpeg streamclip has mkv which is why i use mp4 so far with no issues. My settings are h.264 aac 3000kbps bitrate limit and files are around 2 gb...

I usually rip my DVD's and convert them to .avi or mp4 at 480p or lower and purchase fullHD movies and re-encode them to 480p or 720p when i want to load them in my tablet. As long as the audio is good (i tend to favor conversion to stereo for tablet playback), i'm willing to sacrifice a little in image quality since having movies in fullHD can eat up a lot of space pretty quickly.
Thanks im trying some 480p conversion . Saving about 1/2 to 1 gb going down to 480p...

The difference of 480p against 720p isn't very noticeable if you watch movies with your tablet at arm's length.
720p is HD, and 1080p is Full HD so we do have an HD display. And I enjoy a good MKV Bluray rip on this device using BS Player.
And watching 480p isnt as bad due to the resolution.
Very nice app to convert videos on the fly...
...is Video Converter Android, an app for the Note 10.1.
https://play.google.com/store/apps/...wsMSwxLDEsInJvbWFuMTAubWVkaWEuY29udmVydGVyIl0.
I have many videos in different formats, which sometimes cannot be played on the note 10.1. So I loaded them on my extSD, search in this app for video files, and all are found (3Gp, MPG, everything). Then I just tap on "convert" and the app changes format so that the movie can be played with stock video player.
I do not like to wait hours for video conversion at home til my pc is done with the task. The Note works on even with display switched off, and conversion is really fast.
ensure you rip them as summed to stereo if you are using large bitrates, BS player can deal with 5.1 audio but struggles with higher bitrates as it can only decode 5.1 in software. Stock player can play 5.1 AC3
REWORDED: On this tablet, is there a way to watch a wider-than-16:9 movie so the view size is enlarged/zoomed proportionally to fill the screen vertically? Instead of stretching and distorting a wide-screen movie vertically to fill the screen to get rid of the black bars (top and bottom), is it possible to enlarge the movie proportionally for fill the screen vertically while cropping the sides? That way, the sides are cropped-off, but there's no distortion. Maybe there's other movie viewing apps that can achieve this? I'm referring to only when watching, not encoding. Thanks.
What frame height & frame width do people recommend ?

To be accurate NTSC DVDs are 480 horizontal lines max. PAL are (up to) 576.
But back to the OPs question, I use makemkv to RIP the DVD and then Freemake to recode to generic Android supported codecs - which also decreases the file size by a factor of 3.
Freemake allows you to set a "up to" resolution so one setting of 720p will do for all DVDs and BluRay/HD-DVDs ...

Hello,
I'm trying to create a good preset in Handbrake for Videos to play on my Nexus 7. Can anyone tell me if I would get better results settings the picture size to 1920 (width) or 1280 (width)?
I know the N7 has a resolution 1920 x 1200 but I want to keep the file sizes reasonable whilst retaining decent HD quality?
I'm guessing that if I were to use 1280 x 720 the video would then be stretched to fill the screen thus making the reduced file size pretty redundnt?

I'm not really following you here.
The screen is 16:10, which means most stuff will run with small to medium sized black bars on the top and bottom of the screen while held in landscape. Old 4:3 AR stuff will have black bars at the sides.
If I personally were to make a trip where I wanted to take a lot of videos and didn't have a lot of storage capacity, I'd resize them to be 720p. Unless I were to output them to a TV later on. 1080p on that screen size, I can't really see the difference.
But my advice to you: try it out. Make some 1080p and 720p encodes and then have someone start a video and you have to try and guess if it is 1080p or 720p. If you guess right 50% of the time, do 720p.
I do all my videos at 720p with Handbrake and they look great on the N7. There is a lot of information out there about encoding settings. It comes down to personal preference and the amount of time you're willing to spend encoding videos.
I do most of my conversions at 720p with handbrake. The settings I change are: 1280 width loose / h.264 .mp4, check large file size if input is > 5GB / 18fps/ aac faacp & ac3 passthru (no need for the two audio tracks unless you use an Apple TV which will only use the 1st track)

On a screen this size you will be fine with 720. I have a 1080p projector and an 84" screen and I only notice a big difference with animated movies such as pixars or DreamWorks in 720 vs 1080.

Agreed. Even on my 40" LCD TV, 720p is plenty. So it is certainly enough for a tablet.
The extra resolution on these things is more useful for text based applications IMO. Video is fine at 720p.
So for the longest time, my Note 3 always lagged a bit with 1080p videos, but a few days ago when I just updated to the newest MX Player, 1080p videos now play perfectly.
A majority of my videos are encoded in 720p mainly because 1080p couldn't play right, but now I'm thinking of re-encoding all my movies in 1080p. My question is will it make a difference in quality? I can always tell the difference in quality when I watch on my 42 inch TV since there's some distance between me and my TV, but when I watch my videos on my phone, I usually have it in front of my face pretty close. Would a video in 1080p make a difference to a 720p video even on a small 5 inch phone? I can tell a huge difference between another one of my phone which is 4 inch (480p) vs my Note 3 (720p) when playing videos. I just want to know if there is no real difference, I was going to keep 720p because 1080p videos are damn huge.
Sorry for the long question. Kudos to anyone who has any knowledge on this subject.
The fact is 1080p will technically appear better than 720p. Whether or not you notice the difference will depend on how well your eyes are attuned to high pixel images. While I've never done a comparison on my note 3 I have clearly noticed the difference on an 8in tablet. I can notice pixelation on 4k images and higher but I've been exposing my eyes to them for years now. I honestly don't think it would bother you (or me) if watching videos, but if you are ocd like me and have the original files at higher resolution with the storage space I would probably make all my videos the highest res available based on the original (understanding that without high end video editing software there is no benefit to increasing resolution beyond the original).
Oops I forgot to mention. I actually never had problems with 1080p videos. It was always the ones that were encoded in 10bit + 1080p that lagged. With the latest version of MX Player, SW decoder can actually play the damn thing without much lag. And this is with the subtitle enabled which is pretty amazing.
My eyesight is pretty horrible so maybe I won't notice the sharpness of 1080p much...
Edit - So I tested a few videos. Looks like I overestimated the SW decoding. It's definitely come a long way because there isn't as much as lag as before, but there IS still lag. I actually tested some 10bit 1080p with insanely high bitrates and it lags like a mother still. The lag isn't as bad as before, but it is still there. Guess I will just stick with 10bit 720p for now. No matter how much better 1080p may look, it doesn't beat 720p with perfect playback and no annoying lags.
You brought up the one thing I forgot to mention about differences between the two, bitrate. When it comes to encoded videos (not on a disc), bitrate is almost everything when it comes to quality. My previous post holds true as long as the bitrate remains comparable. If a 720p video has a significantly higher bitrate than a 1080p video, the 720p will view better in almost every scenario.
I don't know at what point the Note 3 will be unable to support smooth playback, but depending on what format you have encoded your videos will determine the quality. What I do know is that bluray level bitrate if far too high for the Note 3. I would take a guess that somewhere between 3000 - 4000 kbps would be the limited to what the hardware could handle but I could be mistaken. What I do know is that using MP4 (or MKV with MP4 encoding) at around 2k kbps is close to the same visual quality (on smaller screens) as any container using H.264 encoding at 3k-4k kbps.

I encode most of my videos in MKV format which is why the bitrate is already high enough. Most of my 720p videos have a bitrate of around 2k-2.5k and that's good enough for me. Most of the 1080p videos are almost triple that amount so I guess it's not surprising that the Note 3 will have some hiccup here and there. Not to mention the size of the files are almost 3-4 times big which isn't really ideal for my small storage.
Anyway, thanks for the helpful reply. Wish I can do HW+ decoding with MX player, but alas that's not possible so I guess I will stick with 720p.
I was wondering if there was some sort of video upscaling present when videos of a lower resolution like 720p and 1080p videos are played. I mean, there's not much point in a QHD screen if even 1080p videos are pixelated, right?
What do you mean? They have to be upscaled, how else would you want to watch them? In a small window? 720p should upscale without any quality loss (1 pixel becomes 4 pixels), 1080p should look great too but with a slight, probably not noticable at such small screen size quality loss.
1080p videos look great on my Tab S 8.4 i don't see any reason why they wouldn't on the Note 4.
Sorry. Yeah, I mean lossless upscaling.

Lossless...?
Relative to the 1080p, sure, it's lossless as you don't lose any resolution from 1080p. Relative to 1440p? Well, in that case of course you lose resolution if the source video isn't 1440p.
Sorry, I'm not too sure what you mean by lossless.
Looks like I've been doing a shoddy job of explaining myself. Sorry about that.
I know that this may sound completely retarded, but what I meant to ask was this : Does the Note 4 have the same type of upscaling that is present in 4K televisions?
