[Q] best movie / video clip to showcase evo's screen? - EVO 4G Q&A, Help & Troubleshooting

as the title says, what's the best video file to showcase the screen on the EVO? i was told avatar but my file's native resolution is 6xx by 3xx so it doesnt fill the screen unless i stretch it, and then you notice the stretched pixels
I was told to try a high-def file. i tried a 720p and a 1080p file and both of them played slowly and skipped on the audio (i have bigger file size videos that play fine, so it must be bitrate causing the skipping)...
thanks for your suggestions

I followed this very easy guide for converting files.
http://www.talkandroid.com/android-forums/evo-4g/5201-guide-converting-video-files-work-evo.html
I then converted Avatar from 720p. Its glorious, and everyone who wants to see the video quality of my phone, I show the Avatar movie.

I don't get it. The screen itself can't display 720p on it. Why even bother? It can't even record 720p. By that I mean the compression and low light capabilities.
But yeah, no point in trying to impress people with the screen, really. xP

well i'm also trying to impress myself. i haven't yet seen video playback at its best settings.
it can't play at 720p but if you get the step down, being standard def. it's lower than the screen res on the evo. so we get 720p and downsize it to evo's resolution which is still higher than the 640x480 type of vga size video.
thanks for the tip. i had found handbrake through a search after i posted. now waiting on avatar and watchmen to finish so i can convert

I convert my BR rips for my EVO, and the best movie I have that shows off the screen is Transformers 2. I converted the IMAX one so it fills the screen

[Q] Touch Pro 2 video recording quality?

Recorded a video last night and uploaded it to Youtube but Im not impressed with the quality.
Checking the settings its set to 640x480 (VGA) but the video is awfully blocky. I was under the impression that VGA recording on the TP2 was rather good.
Am I expecting too much from the device or is there something amiss here?
Does noone have any input on this? Is the linked video what I should expect from TP2 video footage?
What settings did you use?
I use Resolution L (320x240) and Capture Format MPEG4
Comes out fine for me.
Capture Format: MPEG4
Resolution: VGA (640x480)
Its blocky both on the Youtube conversion and on the phone itself.
Could it simply be a result of poor recording venue?
If there is low light this will make a difference. But test and see. Try the slightly lower resolution (because then it can cope with better compression and may be less blocky). Would be interested if anyone else has different settings. Cheers.

Improved 720p recording for both font and back camera - mp4 format

Must have ROOT
EDIT**
I have just uploaded V2 of my profile - I have lowered the Bitrate slightly and changed from 3gp to mp4 file format.. I have also enabled 720p for the front facing camera - Let me know if the lowered bitrate still performs as well.
Folks,
This is my edited media_profile.xml for far better 720p recording.. thought I would share it..
I have upped the bitrate from just 1MB/s (default)to around 4MB/s.. for me, it is clearly better when played on my Monitor or Television.. smoother, more detail and appears clearer.
I have tried a higher bitrate but found this to be a good balance between size and quality.
I have also tried editing the xml for 1080p recording but cannot get higher than 14fps when recording so have not included it..
to install, just unrar the media_profiles.xml and copy it to /system/etc and reboot.... REMEMBER TO BACKUP YOUR ORIGINAL FIRST.
This has worked for me, but if you end up in a boot loop, pushing the original file should fix it.
Hope you enjoy it.
Bracken
Do you have a comparison video or anything? This is the kind of thing I want to see before flashing.
Nice find!
I can see the difference just watching play back on the xoom! Alot smoother...ill check out the HDMI when I get home.
Will this work on any Android device? Say my DX? I take way more video on that.

have you a stock Kernel or Custom Kernel + overclocked CPU?
Works well, I have a similar hack for my Nexus.
Easy and simple improvement for video recording.
Using Hammerhead 2.1 & Tachi OCed kernel.
@bracken21 = does this affect the still camera picture taking?
Thank you very much, great mod.
Hi,
@Sergio PC -This does not affect the picture quality only the video..
@twister_65 -I had this completely on stock 3.1 with stock kernel and worked fined.. I'm now running it with Hammerhead 2.1 & Tachi OCed kernel.
Even OCed @1.6, when I enable 1080p recording there is no increase in FPS, it stays at around 14FPS.. I presume the actual sensor is not capable of [email protected]
@mradlauer - I have no idea if this could be done to the DX, I presume so, but what resolution, bitrate and FPS would depend on the device.. if its anything like the Xoom, putting in an unsupported profile may result in a boot loop ?
If there is interest I can upload another profile with settings as follows... but I find it pointless as 1080p @ 14fps is unwatchable.. I have tried increasing/decreasing the Bitrate but still only does 14fps.
1080p 6MB/s @ 14fps when high quality selected.
720p 4MB/s @ 30 when low quality selected.
720p @ 30fps for front facing camera.
Thanks
Bracken
720p for front would be awesome.
Great, i just would love to have it recording in MP4
€: Wait, trying it now
€²: Works Thx for This
Would changing any of these lines to 100 improve photo quality too?

truly great work here. thank you
im just surprised no one had done this sooner, but better late than never!!
ive only played wtih it for litterally 30 seconds however i noticed that upon pressing the record button for a video using the front facing camera, it zooms in and stretches the image vertically in the preview window. i dont think that it actually records it like this but it seems to be some sort of graphical glitch....maybe you could look into it?
id like to say thanks again. did you change anything for the still images in v2 or somthing? because i no longer see those weird lines when taking photos with the front facing camera.
THANKS!

I've noticed the same issue when recording from the front camera
Excuse me, but trying this mod, I realized that the zoom in camera mode does not work. And 'this normal?
Thanks!
zoom isnt working in video mode for me either.
although i cant remember if we were ever able to.....
can you add this ?
I tried now, even the stock 3.1 does not allow it. Is there any mod ?
Regards!
Nice find.
Pretty easy to increase or lower the bitrate yourself.
I personally upped the bitrate to 35MB/s for 720p.
Adjusted the 480p resolution to 720x480 @ 20Mb/s for quick and easy converts straight to dvd with no resolution changes.
Adjusted the audio bitrate to 256kbps, sample rate to 48khz and enabled stereo recording.
Sweet stuff.
edit: Tried shooting for 60fps but it forced closed as soon as I tried to select video recording

Do you mind posting your xml file... I personally like the tweaks you have done and would like the same..
Thanks in advance

35MB/s is 2.1Gb per minute - that would give you around 15 mins recording on 720p on 32gb card. Plus with the size of sensor and optics, im guessing you wont see quality increase above 3MB - 4MB/s and even that is asking alot of the camera due to the noise levels and lack of light/detail passing through the small plastic lens. As for stereo recording, I thought the Xoom only had 1 mic ?
Being that bluray movies are around 34MB/s.. I think asking a small plastic lens on the xoom to do that a little much. Also the tegra 2 is listed at only supporting 20Mb... did you also amend the codec maximum bitrate as its currently set to around 5MBs.. if not, you will actually be recording @ 5MB/s.. Also, is 35MB/s over the write limit for xoom internal storage.. I could be wrong but even a class 10 cards only write at around 10MBs and reads @ 30Mbs ?
If you want to try 60fps, you would also need to amend not just the recording values but the codec preference and possible the memCap too.. ive not tried it yet, may give it a go.
Im not trying to have a go at you, just stating that your filling your xoom up for no reason... in a long winded blurbing kind away.. not had my coffee yet..
As for the problem with front camera zooming in on 720p, nothing I can do about this, that fix would be above my head.. My guess is that the google camera apk would need amended for 16:9... my knowledge of Android goes as far as this little dirty hack.
Cheers

bummer on the zoom and front face stretch problem... Gonna have to revert to stock unless fixed in the future... Will subscribe for updates in case. Nice for folks that don't mind those couple details though

Hi, just revert to version 1, it keeps the front camera stock and rear camera is improved..
As for the people not being able zoom, you can't zoom in video mode using stock... well mines never has.
I wish I knew how to port the camera front the Samsung 10.1 tab, does any one know how?

[Q] Epic Optimal Video Settings

After much experimentation, I have found that the epic prefers 5:3 aspect ratio. If you want the maximum in clarity and optimized file size for your videos, here are the settings I came up with. Adding more to either bitrate wont help the quality.
Customized MP4 Movie (*.mp4) template in Freemake
Video Code: MPEG4 (NOT h.264 or x264)
Frame Size: 1000x600 (5:3 ratio)
Video Bitrate: 1280
Video framerate: 24
Encode Passes: 2
Audio Codec: AAC
Audio Bitrate: 160
Sample rate: 44100
Audio Channels: 2
Disable Audio: No
A/V Sync: Default
These settings work great on my Arnova 10b (Capacitive) and my Touchpad. They would also work great in an iPad or XBOX. I used the high resolution to fill the screen of my Arnova without stretching. It works fine on my Epic.
Here the question: Why 5:3? Any other aspect ratio does not actually fill the screen. If you make a 800x600 (4:3) video, you will find that the player does not actually fill the screen. Thoughts?
The screen resolution is 800x480, which is 5:3...
Just make the video 800x480, and it won't have to do any scaling.
Interesting. Gonna check my videos and see what res I have them in, because they look awesome as it is.

I did that resolution... It worked great for my epic.. I settled on the resolution I used because it worked awesome on all my devices.. even my touchpad. The cost in file size is almost nothing between the two resolutions.
Ok, I have a 720p video.. it looks amazing at its normal resolution of 1280x720.. no cropping that I can notice..
I'm an editor by trade.
What you're looking for is H.264 in .mp4. I tend to go for a video bitrate that hangs out around 1.5mbps and AAC stereo audio at 160kbps, 44.1kHz. There are quite a few artifacts in the shadows, but for watching a movie on an airplane it'll suffice.
The key to both a sharp picture and long battery life is to properly prepare the video. When your video is under or over 800px wide the Epic has to perform scaling to make it fill the screen (or sacrifice filling the screen if it is under). This scaling is an additional calculation it must perform, which hits the battery, and is a transformation on a lossy codec - a quality killer. If you have the render power (48 i7 cores and segmented processing makes for fast work) you can always hit it with mild sharpening for that extra pop.
Export your video at 800 pixels wide by whatever makes the correct aspect ratio. It's a bit of simple algebra, set up a proportion, cross-multiply, divide, and bang.
ex:
(1280/720)=(800/x)
1280x=720*800
1280x=576,000
x=450
800x450 <-- use this for any 16x9 broadcasts
(1.85/1)=(800/x)
1.85x=800
x=432
800x432 <-- use this for movies presented in 1.85:1, 2.35:1, and 2.40:1.
If it's 4x3 export at 640x480.
I just scale up to 4k. Looks pretty good =D

[Q] Is it possible to do 480p 16:9 (854×480) video?

480p is nominally 640x480 (4:3), but if you look on Youtube, for example, you're not going to find many 480p videos that aren't 16:9, meaning 854x480 (Wikipedia lists that as a valid 480p resolution among several).
Is there a way to either change what 480p is in the camera menu or add a 480p (16:9) selection?
The other resolutions, 720p and 1080p, are 16:9, of course, but I don't always want to squander that much space when the quality isn't needed.
The answer to your question would be no. All of your video would be either sqaushed or stretched.
720 & 1080 are native 16:9 formats. They can be down converted to fit 4:3 and if it was filmed properly it will still look good because the camera man protected 4:3 boundaries while shooting 16:9.
If youve ever seen a 16:9 movie on an old 4:3 tv you will notice that its letter boxed and down converted to fit the screen.
Most consumer and prosumer cameras are 16:9 by default now because all of the displays on the market can show that content properly.
I don't follow your first sentence. I can understand the phone simply not being capable of doing it (I'm still hoping that's not the case, since 3rd-party ROMs often can do wonders), but if it could, then I don't see what the problem would be recording 16:9 480p (854x480). I would even think that it would be more popular than 4:3 480p.
Also, I have to think that 16:9 480p is quite common, since how else can so many 480p videos on Youtube be 16:9 (and these are often videos that top out at 480p, so they're not down-converted from something higher)? Phones are by far the most common video recorders, yet I can't recall the last time I saw vertical black bars on Youtube (what you get with 640x480).

Any good resolution changeing apps?

I love,that g4 can take videos at such high resolution.
I dont want to record in a lower resolution, (i know just use another recorder app for that).
I want to record in high resolution, make a copy of video, and then drop the copy resolution so i can have a high ando low resolution.
Reason is because if i try to play videos i recorded on my g4 on my TV, itsays video resolution not supported. Nd its a smart TV ? also when sharing videos to other phones it has came up as "video unsupprted" or "resolution unsuportted"
Any reccomendation for resolution changer?
