i'v tried now shooting 10 sec video @4K both formats
at H.264 the size is almost doubled (60MB)
H.265 the size is (34MB)
besides size i didnt see clear diffrents (maybe better support on another devices?)
what are you using
p.s i prefer @60 fps FHD then @30 FHD there you can see clear diffrents
Just look it wikipedia : https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding
High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard, one of several potential successors to the widely used AVC (H.264 or MPEG-4 Part 10). In comparison to AVC, HEVC offers about double the data compression ratio at the same level of video quality, or substantially improved video quality at the same bit rate. It supports resolutions up to 8192×4320, including 8K UHD.

Thanks, after a bit more try attempts, i figrued out that sometimes post prosses abit better on 265(sharper corners , BUT make the phone hot faster, also use 90% CPU on my computer(i7)
so ill use it when i see my phone running out of storage if i dont have computer near by to backup my data
How did you use it? Can you suggest some good apps?

You can use it in the Sony camera application, just choose 4k video and press on the menusymbol in the upper left corner. The first entry let you choose if you want to take videos with H.264 or H.265.

I'm seeing conflicting information regarding the 2D video recording, some info states that the Evo records at 30fps, but I've also seen 24fps mentioned. Also seen mention that it records at 720p, then also 1080p. I'm confused!
Can anyome confirm either as being correct?
Anyone?

Here is a great review about out HTC EVO 3D... Look at the Camera paragraph...
http://www.techtree.com/India/Reviews/Review_HTC_Evo_3D/551-116000-614.html
Thanks for the lnk to the info.
The phone can record 720p video at 30 fps. The clips are saved in the MP4 format, which is a big improvement over the Sensation's 3GP. The resulting clips are pretty smooth and contain a reasonable level of detail. Additionally, stereo sound recording is a nice feature. Strangely, despite having a dual-core CPU under the hood, the phone cannot record video in 1080p. As before, recording videos in 3D produces fun results

Just got back from my local Carphone Warehouse, they have the Evo and the info show on the display say's '1080p video recording'.
Just wondering...else I have to convert to 480p
Yes it supports 720p (and 1080p) movies.
you guys have to always remember that what it supports and what it can do flawlessly are two separate things....
720p videos films are playable but not the smoothest.
actually,For me,720p and 1080p vids played quite smoothly (maybe a tad slower than my iphone4 but nothing notable really)
Interesting, I didn't even try 720p. Good to know it works, but really it generally would be worth your time to convert. Huge waste of space if you don't plan on deleting it right after viewing.

Yup I had to convert a 2.5 gb vid from avi to mp4 and it was about 3.7gb

I assume you used Zune to convert it, if the end file ended up being bigger than the original.
A properly transcoded video would be significantly smaller: a 720p video has 921600 pixels per frame, as opposed to the resolution of our Titans; 480x800. A wvga video only needs 384000 pixels per frame. Therefore a 720p video is roughly 2.4x larger than it needs to be as our screens cannot display pixels it doesn't have (and that's not even taking bit rate into account). The quality will actually be slightly worse on a 720p video because it will have to be scaled down to play on the screen, whereas a properly transcoded video would be 1:1 with the pixels on the screen.
I mentioned bit rate; I don't really know what a good marker for bit rate is, but when transcoding to a smaller resolution, you don't want to keep the original bit rate: that has to go down too. Bit rate plays into file size significantly, so in reality any 720p video is much more than 2.4x bigger than it needs to be.
I guess one of these days I'll play around with a transcoder and make a thread about how to properly convert a video for WP7.
Hi all
What is the general consensus for the best resolution for playing movies on the tablet considering the screen it comes with?
I am heading overseas shortly and so wanted to look at whether I convert some of my large movies to a smaller filesize and if I do what resolution is ideal.
That of course could lead on to the app people use for said conversion (but that is very subjective to each individual).
Cheers
Well since our screen supports 1080P i would say that is also the ideal resolution now I don't think that your movies are any higher resolution than that so it is also very subjective what resolution is 'optimal' it will always be a tradeoff between quality and filesize, personally I don't really see that much difference between 1080 and 720. With 480p I do really see a difference. But I would say that is sufficient for your trip.

The ideal format for the XPERIA Tablet Z (and well any other modern tablet) is h.264 .mp4 AVC. The tablet's screen is WUXGA (1920x1200), so itnis perfect for 1080p. Sony's official whitepaper states the device supports up to 20Mbps, somI recommend encoding your video to that bit rate for maximum quality. A bit rate of 15Mbps is also a good compromise if you still want high quality, while 11.5Mbps is still ideal. 7.5Mbps 720p is also suitable if you dont mind sacrificing some quality.
I have an eye for low quality, but if you are dealing with feature length live action movies here, handbraking them to 10Mbps h264 1070p should do.
I myself use 15Mbps. I can provide a screencap of a 15Mbps video on the tablet if you want one.
Mi 9 tested by DxOMark records 4K video by default. It scores significantly higher for video texture and detail than other smartphones whose video quality is tested in 1080P . As a result, Mi 9 gets the highest score in the video part. Today the retail unit of Mi 9 receives software updates to change default video recording setting from 1080P to 4K.

Xiaomi cheats in the DxOMark video test for Mi 9. Dxomark only test the default setting of smartphone cameras. And the phone tested by DxOMark records 4K video by default. However, the phone sold to consumers records 1080P video by default. Because of this, it scores significantly higher for video texture and detail than other smartphones. As a result, Mi 9 gets the highest score in the video part. A vlogger in China went to Xiaomi store to check the default video recording setting for Mi 9. It showed clearly that the default setting is 1080p instead of 4k.

Quote from article:- "In terms of video, (slow motion at 960fps available) the Mi 9 manages to surprise - the default recording in 4K produces great details even when shooting indoors."
I can only speak, based on what I have read, until I see evidence that states otherwise, I choose to believe Xiaomi & the reviewers, I understand I may be proven wrong...
Tgey still are people which trust DxO?
The camera seems to be still on par even with the S10 or the iPhone XR - for half the price, we shouldn't forget that.
I ve tried wm size command but it no longer work since it is Android 12.

Is there any merit to doing that?
I'm middle aged and with not-so-good eyesight, but fhd for me is more than enough.

I just never see it enable 4K even I m viewing images with gallery app.
So I just want to force it for better experience.

I'm not convinced, if this would be visible. Probably depends on your visual acuity.
Mine is not the best, and for the life of me I can't see the difference between 1440p and 1080p on such a small screen.

There IS it, I ve paid for it, and I WANT it.
And experience will be different for me when viewing large size image in 1:1 scale.
It is just like refresh rate, since there r people cannot get the difference between 120hz and 60hz(or lower). But you cannot just disable higher refresh rate FOREVER just because there r some people cannot distingurish.

It's also to remove unnecessary downscale/upscale when watching a 4k movie. Since most app view the screen as a QHD one, VLC for example, will render a 4k video as a QHD one by downscaling it, then the phone will upscale it back to 4K.
Sure you will probably not see a lot of difference with native 4k as the upscaling technology from Sony is pretty good and you still have the 4K screen resolution giving extra sharpness.
Also, what some people seems to forget, is that the image displayed will always be 4K on this screen, a FHD image will be upscaled to 4K by the phone, and the higher pixel density make it far better than the same FHD content on a QHD screen especially for AMOLED screen that are somewhat blurry on the edge due to the subpixels arrangement.
This being said, you can put the screen in native resolution all the time, just going in the developper option and setting the screen minimal width to 1644pixels to match the 1644*3840 pixel resolution. Doing this, VLC that I tried perfectly render a movie in 4K, but your overall UI is ****ed up and you can barely use the phone. That's not what is wanted. Sony is just boring us for 4 generation with its 4k white list apps. I don't even know what is the recommanded app to watch their 4k HDR spiderman extract.
It's stated that the screen only runs at 4k in certain apps and scenarios, Theres no option to change that.
More accurately: The phone only render graphic at 4k in certain apps and scenarios*
The screen always runs at 4K since it's hardware and number of pixels can't physically be changed. The phone upscale every content to 4K all the time but render some whitelisted app directely in 4K. Still better than proper 2K as the pixels are smaller, but also mean your 4K videos on VLC will be downscaled to 2K by VLC then upscaled back to 4K by the phone, only because Sony didn't whitelist VLC that is perfectly able to run native 4K.
I almost have the same question, but instead of 4K I want to set a global 2K resolution.
4K is way too overkill, but 2K is the best middle ground between display clarity and battery life.
that is what you basically have, 99% of the time your phone won't render 4k. Doing that for all scenarios in which things are rendered in 4k would make absolutely zero sense because then they would need to be upscaled again to fit the 4k reselution
