Hi,
Could someone tell me what the correct settings are to encode video to my XDA. I need screen resolution and FPS also Kbps.
Video Encoding for Pocket PC
The simplest method of encoding for the pocket pc is to encode using windows media encoder. Simply download the encoder from
http://www.microsoft.com/windows/windowsmedia/download/default.asp.
Once you have it is very easy. There are templates for pocket PC.
Voila!
I have noted however that mpegs encoded for the pocket PC look and play better. I have not compared with the new encoder though. To play mpeg files you need mpegtv.

Also, with WME9 you can tweak quite a few settings to customise it for your needs, although it's far from intuitive. I use it myself to encode movies for viewing on the train, quite acceptable quality, full-screen, stereo, 20fps, at about 1MB per minute.
I've been asked to share some instructions for Windows Media encoding, as the existing how-to guides only cover divx and mpeg: so here goes...
1) Get the software - Windows media encoder 9 - from Microsoft here
http://www.microsoft.com/windows/windowsmedia/9series/encoder/default.aspx
2) You can use the wizards to covert for pocketPC, but as this is about tweaking for optimum performance, select the custom setting to create a blank project and bring up the session properties window. I'll now go through the tabs on the session properties:
Sources) WME is very flexible, and allows you to use multiple sources, but in the case of simple file conversion, just alter the default source. Select the File radio butto on the source from section, and browse for your file.
Output) Select the Archive to File checbox, and then browse for or enter the output filename. Note WME will helpfully set the extension to wmv automatically. Make sure the push and pull checkboxes are cleared.
Compression) Here's the fiddly bit. Why they don't allow you to create and save off a complete custom destination is beyond me, but select a destination of PocketPC and click edit. We'll now go through the compression settings dialogue:
- General) For pocket PC you want to use Audio: CBR: Windows Media Audio 9, Video: Windows Media Video V8. You now need to set up your target bit rate. Windows media allows a single file to have more than one bit rate, so that if it's viewed over the internet, a different stream can be sent depending upon the bandwindth. As we're going to be creating a single file, we'll only want a single bit rate. Remove all the target bit rates and add a new one. Give it a bit rate of 120K - note this pop-up window is a bit superfluous, it just alters the caption on the second tab, from where the real bit rate can be set:
- 120 Kbs) OK here is the main tweak page for the compression. Here are my suggested values for a very higly compressed, but watchable file:
Audio format: 20kbps 22KHz stereo CBR. You can up this if the sound quality is very important, but don't go too high otherwise the PocketPC won't have enough power to process the file.
Video Size: use a calculator to work out the correct dimensions to produce a full screen on the pocketPC, given your original video size. So if the original video was 352x240, we want a width of 320 to fit the screen. 240*320/352=218ish, so the size you would want is 320x218.
Frame Rate: High frame rates can require too much performance than the pocketPC can provide, but it's worth playing around with this one. I tend to go for 20fps for movies, 15fps for animation (such as Southpark )
Key Frame Interval: If the PocketPC video stalls because of peformance, this is effectively how long you'll have to wait before it recovers. Lower values produce bigger files, but higher values make stalls more irritating. I tend to use 4s
Video Bit Rate: One of the best things about Windows Media is the bit rate is totally flexible. You'll definitely want to play around with this one. The higher the bit rate, the bigger the file and the better the qaulity, but the more power required to play it. 100K bps gives a not-crystal clear, but perfectly watchable result.
Buffer size: I tend to leave this at about 5s - it affects the total memory required when watching the movie, but doesn't make tht much difference.
Video Smoothness: This setting is a little fiddly. It determies whether you want a smooth but slightly blurry video, or a sharp but jerky video. It depends on what you're encoding. It's a percentage value. I generally use 5 for action movies, 15 for southpark. Keep it low, otherwise you'll get a slideshow on the PocketPC.
Once you've set up your values, you'll probably want to use the export button on the General Tab to save this off to use again.
Back on the compression tab) Initially leave two-pass encoding unchecked, so that you can encode just a bit of the file first to check things are OK. Once you're happy with the results, you can select two pass encoding to produce slightly better quality results.
Video Size) As we set up the correct video size on the compression settings, this is a bit superfluous. However it can be used to crop borders off letter-box content, which saves a bit of space.
Attributes) Set up how you want
Processing) If the source is a poorly encoded video, you can de-interlace, or if it's a movie that has been recorded directly, you can inverse telecine (telecine is where they change the frame rate from film at 24fps to video at 25fps). I tend to leave it as None.
Plug-ins) OK this isn't really important, unless you have a DVD rip that has very quiet sound. There's no simple way of amplifying the sound in WME, so you need to use an audio plug-in. I've used Scrollworks Peak Slammer with good results, but it's quite costly for a simple audio amplifier. I'd be interested to know if there's a simple freeware audio amplifier plug-in out there. http://www.scrollworks.com/products/slammer
Security) Leave blank
Advanced) Leave the defaults
Now click apply!
Ok don't go the whole hog just yet - click start encoding and let the first 30 seconds or so get encoded, then stop the encoding. This doesn't delete the partially encoded file, so you can check the output to make sure it's OK. Click the properties button to bring up the properties window again, and alter any settingas you feel need changing here, such as volume, size, compression, smoothness etc. Keep doing this partial encode/tweak settings cycle until you're happy with the results.
Once you have good session settings, go back to the compression tab and select two-pass encoding and click the apply button. Now press encode and wait for your file to be produced.
Hope this helps
having played with encoding quite a bit, i have to say that when disk space is a problem, nothing but divx is worthwhile.
Get the DIVX codecs from www.doom9.net
Get the application virtuadub from the same site
Now you can open any avi,mpeg file in virtuadub, and encode it using the divx codec. Apply a resize filter if you want to make the screen size smaller. Use some audio codec settings to reduce sound quality, and you will have a movie, not DVD quality, but watchable, and doesnt take hundreds of Mbs.
Use pocketdivx http://www.projectmayo.com/projects/detail.php?projectId=9
to play the movie.
Also found a great audio tool to decrease the size of mp3 or WMA files.
DbpowerAMP from http://www.dbpoweramp.com/ allows you to covert audio formats, and to reduce quality.
Managed to get a 5Mb mp3 file, to 900k WMA file, and it sounded good on the xda
I've noticed that video playback on the XDA will be a lot smoother if you turn off the phone while viewing. Probably something to do with the phone being a realtime application with high priority.
Hi I wanted to know if it is possible to improve to improve audio recorded during a video??
I mean I can record video at 720p 25 fps, but the DAMN audio gets recorded at 12 kbps!!
It's just tinny and annoying sound cuts up all the time.
So it is it possible to increase the bitrate of audio via modifying some system file or changing some parameters in phones hidden settings or something like that?? my phone is a Chinese Zopo PILOT ZP100. Thank you.
btw, When I use Sound / voice recorder, it records in 3gppp at high setting with 127 kbps AAC audio.

some users with the same problem on other phones use this app with AMR_WB encoder selected and they reported a significant audio quality improved during video
Try it, it might work
Thanks mate. this actually CAN record high quality audio but the video even when selected to record at 30 fps , reciords at 10-11 fps, I guess its my Class-4 card...
Perhaps compare the data rate required to store video+audio data compared to audio data only, and also account for the lower transfer speed of a class 4 SD card compared to class 10. There might be other limitations as well - if a product is sold as a mid-range phone the picture quality may be deliberately downgraded compared to what the hardware is capable of. Samsung galaxy ace 832MHz arm CPU with class 10 SD card = 320 x 240 video recording

when I use native app to record video, it records with bitrates of 11,000+ and 25 Fps! Just that audio is ****ty 12 kpbs!
With the lgcamera app as I reduce the video bitrate the fps goes up so I think it is a bandwidth issue only but then the native camera app can handle such high bitrates....!

try to find out what encoding is used for 720p in the stock camera app, and make sure it's the same in lgCamera.
with the wrong encoding settings your phone may fall back to software encoding, which is much less efficient.
my phone for example is capable of 30fps 1088p video recording, but using software encoding(hw en/decoding is broken in the rom i use) it can only reach 30fps on 480p, or 720p if i overclock.

Don't know, I guess the free version is capped at 20 FPS cause no matter what parameters I set frame rate doesn't go past 20 FPS...
The default encoder for phone was H.263 in 3GP container. still it doesn't make any difference. I was thinking about editing the Media_profiles.xml in ETC folder but it's not even there!!

Hello,
I have Zp200 and I have the same issue about audio quality... and Lg cam software does not work properly (sometimes close and lock the phone during record).
Do you have any new about how to change this bitrate?
Thanks, Caio.
I have a HUAWEI g300, and while the quality of still images taken with the camera are great, video quality is awful. Or, to be more specific, the audio that goes with the video is very poor.
I believe that this may be due to the file format of the video.
For this reason, I would be interested to know whether there are any ways to change the file format which videos are recorded in. Are there any alternative camera apps that are any good, which ideally allow the user to select their own file format? My device is rooted btw.

Hi,
I have a Samsung Galaxy S4 ZOOM (SM-C105).
I use it at work to record videos (1280x720), send to the company after previous encoding to a lower bitrate. (to reduce file size) - which unfortunately takes a long time.
I would like to change the settings to immediately record a lower bitrate.
The phone is rooted and I tried to edit the file "media_profiles.xml" but it does not change anything. Even threw him out of the catalog and still camera records the old way.
Edited the file on the phone and copied another. I have a feeling that my phone does not use that file.
Did I do something wrong? Can I do it differently? Where do I change the settings to reduce the bitrate?
I tried to use other camera.app but they are not suited for this camera (optical zoom etc.)
I will be grateful for your help.
Regards
Lech
Hello, as you know, the Huawei screen recorder does not record in FullHD, only in HD.
The application consists of 3 files, apk, dex and vdex.
He is looking at the file and I do not see anything for the resolution, I intuit that the file to edit is VDEX ...
Could someone edit the application to record in FullHD?
It is also possible to add 320kbps of audio to 48mhz (I do not know if it is already that way)
Also, record at 18mbps bitrate.
It's very easy, just look in VDEX for the current resolution 616x1280 or 1280x616 for 1920x1080 or 1080x1920.
I need that application and that is the only voice that records internal audio.
Greetings and thank you.
PD: In a while I upload the files
