What is the Best Video Resolution..???

Well I am converting my fav know movies & puttin them in my SD card I wanna whats the best video resolution I can use to get the best video output as well as save some space on my SD card..!!!
PS : - Can you also suggest me the codec, I mean the video type..!!!
Thank you..!!!

Well screen resolution is 800x480, so that's gonna be the resolution you want. Format wise, use mp4 since that will play in the stock htc player and will therefore use the hardware acceleration.
Also, please use search as this has been answered. There's even tools that developers have made that will auto convert everything for you. Again, please search before starting a thread.

The ANS is here..!!!

LoLz I found it myself, thanks anyways my Q is answered..!!!

i convert my vids to mp4 with 400x240 res.
this is the quarter of hd2's wvga res, so it fits with 4 pixels on display and wont be stretched.
800x480 is too high, i need my storage
so for me, 400x240 is perfect. a 1,30h long vid needs about 320mb storage.

Newb question: Best video decoding settings.

Im going to try and make this short.
I realize this may not be the best place to ask but i know you guys are the best to ask.
What are the best 1) resolution 2) bit rate 3) quality settings for encoding video for the gtab that give you a nice picture and dont break the ram bank.
At 768x450 2000bits/sec My test movie is 1.3gb. At the native 1024x600 the file size hits in the 1.7gb neighborhood (nice looking but probably not feasible unless i am only going to put one or two movies on here at a time...would like to do 5 or 6)
I tried it at 512/300 (50% of the native resolution) and a bit rate of 800bps and did manage to get the file at around 500mbs but the quality was just sub par for my tastes (fuzzy VISIBLY jerky).
Rather than me testing for days and days..i was wondering what settings you guys had set on (and why).
Thanks!
Allen
Edit: The H.264mp4 format was causing artifacting that i couldnt fix at any setting..
Right now i am using .mp4 at 768x450 (or a 75% scale of the native resolution) and a bit rate of 1,500 with the sound set at DVD quality (which actually does help since i use blue tooth head phones). File size still just at 1gb (that maybe about the smallest i can do with the quality i like). Even at that setting...its still a tad jerky. What should i try? Lowering the resolution and upping the bit rate a tad more???
Still wanting to know if any of you guys have a magic setting for me!
The good news here is that i am not loading my up memory with mp3/songs (have an iphone for that) using pandora radio instead. Regular apps dont take up too much room so i figure i probably have around 10G to play with for video. (when vegan gets the SD card utilizatin fixed ill have another 8G on top of that).

Bump:
Still looking for settings suggestions.

I am using 720X480 @ 1,500kbs in MP4. This gets me ~1.2gb files. It is the actual resolution of a DVD, which is where my material is sourced. This lets the display device do the scaling, rather than the encoding process.

Duh that makes total sense!
Testing now.
Any ideas what the "video quality output settins are". 1 is best, 32 is worse. 26 is recommended.
I dont have much to go on. I see the recommended settings for an ipad are 1335 bit rate and a quality setting of 24.
UPdate: When i did a test run with higher settings i noticed the video would lag every three or four seconds. I concluded that the settings were too high for the hardware to handle. Likewise when i set them too low..it was jerky, and i concluded the bit rate was too low for smooth frame rates.
At 720x480 1500Bits (and a "quality setting of 24"). The lag is MUCH better, but it still lags about every 20 seconds or so (very briefly). I will test at 1400bits/26q and see what happens.
Jeeze! A lot of work.... its too bad someone hadnt already figured all this out and just given me the quick answer! lol
Thanks again for the answer!

You should be able to play 1080 with no lag?
Sent from my V9 using XDA App

You may want to grab a program called Mediainfo. This program analyzes the video file and tells you what profile was used, video and audio encoding stats. I was using this to make sure my source and output files were not using the "High" profile. I have some 1080 files re-encoded under the "Simple" profile and they look great with zero lag. I have re-encoded all my files with Handbrake and the all work without lag.
I used the info listed in roebeet's FAQ post: http://forum.xda-developers.com/showthread.php?t=842899

BUT why when the screen resolution is only 1024x600?
DONT need media info unless reatail dvds are encoded with more than one setting Are they?
I saw roebeets post about using the ipad settings but that makes no sense. THE ipad has a different resoultion and a less powerful processor.
I am getting lag at 720x450 1500bits but not at 720x450 1400 bits. Very interesting.

[AppRequest] PhotoEditing App with Camera RAW file conversion

Hi Developers and everyone, firstly I must say I do know it might not be that easy to archive at the moment, limited by the hardware and software, as these sort of app isn't that common in iOS either.
As soon as the introduction of iPad 2, I had a thought of buying one for the purpose of "on the go photo browser" when I am out for holiday, which I could transfer the RAW files from my DSLR onto the tablet as a storage, viewing and RAW to JPG conversion, with some simple editing/adjustment ability (brightness, contrast, etc) as a bonus.
As I have aware there are 1 or 2 apps on iOS appstore that could do what I mentioned, but there are comments about these apps that the conversion time is very long, as well as the transfer from Camera/card reader to the tablet (iPad2). Having said that, I do see people using this solution when they are on the move, I only gave up because of the price of the iPad2.
As I am lucky enough to bought the Touchpad at such low price, the same idea arise again. I have seen test about the possibility of using the Touchpad as a usb host device, it seems to be possible and achievable.
Would there be any developer able to write such an app for TouchPad?

As cool as this would be I don't think it is likely to happen because it would not be very practical. Raw images are large, complex, and each camera requires a slightly different "codec" (For lack of a better term) to make viewing possible.
The two largest reasons I see for this are speed and limited storage when other options are cheap. The process of offloading images directly from the camera onto the tablet will be slow. Storage on the tablet itself is limited. Large high quality memory cards are cheap now especially if you use SD cards. Class 4+ 16gb SD cards are usually around $20 or less. CF cards are more expensive but not by a ton. With todays cameras producing RAW images that are in excess of 25-30mb each that is not much space for vacation, etc. Your better off with a external hard drive and a small laptop/netbook for pure storage.
The biggest reason I dont see this happening is speed. It would take FOREVER to convert a RAW image from a modern camera. I have a 18mp Canon 7D and it produces RAW files that can be around 30mb. My laptop is old at this point, 2ghz Coreduo processor and it took forever to open an image, make my changes in the raw engine and then produce a non raw file. On my i7 930 this takes significantly less time, but it is a much faster processor. The TP even overclocked is just not built to do this level of desktop type work.
Last thing is since Raw files are flat (colors, sharpness, black levels etc) raw images converted to jpg will look flat and not be something you will want to post online or anything until they are edited up.
Basically if you want to do this, shot in jpg then it all becomes possible.

720p media files

I recently got a new laptop that has an HDMI extension and sense I don't need a laptop when I have a smart phone I just want to use it as a media center. I have an old PC doing the job now so this was a welcome replacement.
Problem is I'm lost when it comes to 720p media files. I've noticed that the size of the files can vary greatly from 2-3gb. For instance "The Green Hornet" is 720p 1.37gb. Then I found another one that is 720p but 3.47gb.
I'm assuming the larger one is going to be better quality but by how much? Is the difference going to be substantial? What do I look for exactly?

The difference in size is most likely due to different encoding. So where a general rule says bigger file = better quality this is not always the case with good encoding techniques. So if the smaller file is sufficent in your eyes, go for it.

what apps let you record without a time limit?

what apps let you record without a time limit?
I heard that with the stock android camera app the time limit for how long you can record is about 30min, even if you have a big SD Card.
And I heard that the max limit is 4GB but you can't get near it with the stock camera app (and I suppose SD cards won't generally be that big)..
But I would like to record for e.g. > 30min sometimes. So, does that 30min or some time limit exist and if so , what apps let you record for longer than the stock app, storage permitting?
Thanks

SD-cards are FAT32 formatted. On this filesystem the max filesize is 4GB.

@jwoegerbauer well whether you are on point or not, besides the 4GB file size limitation, I heard(though not a good source), that there is a 30min time limit that hits first. And that there are some apps that don't have this time limit. And i'm asking if this time limit exists and what apps don't have this time limit?
And actually, https://pocketnow.com/android-11-finally-lifts-the-4gb-file-size-limit-for-recording-videos-sort-of There is a 4GB Android limitation that has been lifted recently. (So, nothing to do with FAT32). I don't nkow if maybe an SD card can be formatted as other than FAT32 eg exFAT or NTFS., on Android..
They mention that the Open Camera app can shoot larger than 4GB (no doubt not on FAT32).
The suggestion then is maybe the stock camera app can't.
I suppose if the stock also has a 30min limitation, then the open camera app won't.

I notice that one of my videos is 1hr long so I think maybe there isn't a 30min limit!
Though my recording isn't 4K. I just read
"Only 4K video recording has time limit of 4 to 8 minutes(phone to phone varies) as it takes large amounts of storage space on your device and heats up the device to much greater extent. So to eradicate these two things, companies limit the video recording in 4K UHD in their devices. If you are recording in Full HD, 720p or other lower quality and have ample storage space in your phone to save those recordings then you can record as much as you want. "

@gardina
I only pointed out a technical fact. Nothing else.
If others know better, then be it.
BTW: I no longer participate this thread because I'm not interested in your issue at all.
