Is there a setting in the Voice Notes where you can change the file output from .amr? I'm looking to get a better recording quality.
Thanks.
Hi,
I was wondering if any of you guys know whats like the ideal bitrate of a file (especially mp3 files) before putting them onto the phone. I'm using this great software called cdex that allows me to downsize a file majorly by reducing the bitrate. But am I compromising on sound quality for space on my card by doing this? The software turns a 6MB mp3 file into like 3MB. I remember reading somewhere that most handheld devices (phones, MP3 players etc) cant play files of a bitrate higher than 80-90kbps. Meaning u cant tell the difference in sound quality after 90 kbps. Is that really true? If someone out there knows....please do let me know.
Thanks in advance

Man, the guy who wrote it probably was from XV century
I'm always copying the same files I have on PC, without converting or something. Just copy - paste. Elf supports SD cards up to 16 GB, so I don't think file size is a problem. If you really want to convert files, use 128 kbps, it should sound good and don't take too much space.
I have a normal of audio files for work, and would like to have them avaialble on my phone for use, but they play in the wmp and coreplayer really high and garbled, is there a solution to be able to play these files at normal levels, ideally with the headphones if that helps?
the HD should have no problem playing a 24kbps .mp3 file as most songs are atleast 128kbps and going up to 512kbps. Have you tried playing these files on a PC with good results? It might be that the files themselves are garbled since 24kbps is really low audio quality (especially in mp3 format).
yeah even 64kbit/Sec mp3 is very bad
I think he means mp3s with 24 bit audio stream (normal mp3s are 16bit), personally i dont have any to test do you have a sample you can provide us?
they play fine on the pc, but that i guess has much better audio capabilities?
i will get a sampe this evening when home from work.
i dont know if it would be a hard ware limitation, or a programme that is needed to "upscale" the quality?
i havent tried using a .mp3 editor to save them as a higher quality, as they are large files (in length,) so the size needs to be kept down
will upload later,
Thanks
I did not know it was possible to upscale a .mp3......to me that should produce the same quality but in a larger file...which is certainly not upscaling but wasting space (what I always thought that an mp3 did was cut off very high/low frequencies and then use a compression algorithm on what remains, hence why a 45mb .wav becomes a 4.5mb .mp3). The HD has more than enough umph to play the 24kbps .mp3 and so I'm very confused as to why you're getting such poor results. Hopefully once you paste a sample file, it will all get resolved.
It isn't possible to upscale a mp3. You'd only be changing the bitrate, increasing the size and not adding to sound quality. Cause a mp3 is in some way a compressed (or ripped, however you want it) file, the lost data in compression cannot be retrieved. 24kbps is awfully low.
Guys, my video recording does not work in 640x480 nor in 320x240. Sound is recorded, but no video... Only CIF works like expected (Video with sound).
Anyone else with that prob?
Thanks,
Marti
Hi,
i got the same problem.. there are only sound on the video recording..
The same after installing "ringtone-patch".
got the same problem. only works in CIF resolution with H.264
I do not have any problem recording video both on momory and SD card and with sound in 640x480 / MP4.
Could you explain how to reproduce this behaviour ?
I fixed it by deleting HKLM\Software\HTC\Camera\recparam\MP4VGA registry key.
If you afraid of deleting, try to rename it.

YESSSSSS!!!
It works fine after deleting of this reg key.
Best regards to all,
Marti
is it really working?
when I bought HD Mini the recording in VGA quality worked fine. I did some customizing (nothing unusual- just installed some apps and tweaked manila to my liking) and.... the VGA mode stopped working. It records audio only. I tried to delete the MP4VGA registry key and after this HD Mini records video in VGA but:
1) the video quality is very poor when compared to the recordings before problems. I checked the files- the resolution is the same (640x480) but the bitrate is drastically lower- it is 375 and used to be 1441. it looks awful
2) the funny thing is that when I opened the registry editor the deleted key is back again. I am a newbie to registry editing and have no idea if I deleted it the "wrong" way and how it restores itsef. I tried several times and after soft reset the key is back again
My most important question is: mrmartischmi and darknos- can you record a high quality files ( hi bitrate?) after the tweak?
thank you
@robertszydlo:
Sorry for the late answer.
You are right:videos have a very low bitrate and thus are of bad quality.
Its false to delete the folder MP4VGA.
I restored it from my backup and set the key "Bitrate" to 1500000.
This made my Videos look much better and the Bitrate returned to be about 151 kBps instead of only 40. Higher values did not work though.
Hope this helps, I am investigating more at the moment...
(maybe someone can post the complete "original" keys of the MP4VGA folder?)
Thanks so far,
Marti
yeah! this one really works (Thanks mrmartischmi!) but it gets me even more confused
after setting the value to 1500000 my phone records great looking videos but the files and the bitrate(well over 3000 now ) are huge! I don't have a problem with large files - it just makes me think:
-what was the original value ( can someone please check and post?)
-why in the world it stopped working? can I expect now to work continuosly and not fail while recording my masterpiece video ?
thank you
@robertszydlo:
I only got 151 kBps, how can yours be 3000?
Did you check on the PC with Quicktime or something else?
Could you post the size, duration and bitrate of a sample video so I can check with the parameters of one of mine?
I am pretty confident, we will understand it in the near future

I'm using 1.32.479.2 WWE ROM with the last HTC hotfix installed. Bellow is MP4VGA key folder, exported from my registry and a screen with info about a short video i've just made.
I've checked the "bitrate" key and mine is 1500000 too.
Hope it helps.
EDIT: the keys have the original values and i don't have any problem with video recording.
mrmartischmi,
I am not any math expert so I can make mistakes- that's why I don't try to convert bits to bytes or do any math I just give you the numbers I see on my mac screen when I "get info" about the new file (value in registry set 1500000) it says it is 640x480, codecs MPEG-4 Video, AAC duration 00:16 audio channels 1 , Total bit rate 3,217. It is probably the bitrate of audio+video in bits? I am not sure how it compares to your 151kBps but your bitrate can be video only expressed in KB.... there are probably many guys on this forum that can enlighten us
ci6i,
thanks for help, the one thing that is strange to me is that before any tweaks my phone recorded files with much smaller total bitrate ( get info says 1486) so maybe in my rom the original registry value was lower?
anyway, yesterday I recorded really long files and everything works, so I am happy
@robertszydlo:
Sorry, it was not my intention to bother you with maths... I was just wondering, why the rates are so different although using the same keys in registry. Could you post the filesize of the small clip you mentioned before so I can compare these parameters to a clip of mine?
@ci6i:
Thanks a lot for your help. I compared the values of the reg key to the ones I have now and they are ecactly the same.
So the question is: why did robertszydlo recorded videos with a much smaller bitrate before the tweaking? Maybe there are other keys to change ...
I'v discovered days ago that this bug is generated by using BsB Tweaks with option "Video MPEG4 Bitrate" enabled or HD2 Tweak with corresponding option enabled..........don't use this tweaks utils if not certified with HD MINI....
hi mrmartischmi,
I uploaded 2 videos- nr 1 is recorded the first day I got the phone, no tweaks
nr 2 i after the last tweaks (value 1500000 in registry) ... bigger bitrate ant bigger file. Can I see difference in quality? well- I am not sure- see for yourself
@ SoftWord: you are probably right! I switched the bsb bitrate tweak on, and this could cause the whole problem, thanks for your input
The best quality I got when remove all keys from MP4VGA registry folder except one: BitRate = 1500000. but 15 seconds video is almost 6Mb on card
Notice: If you leave FrameRate = 20 or 30 in MP4VGA, video file size will be about twice less and quality will be worse.

def that's the problem why the video recording not working. without it my video recording's working fine.
watch out with this setting, guys!
Is there anyway to take a MKV or HQ 720p files with 5.1 surround sound or 3F2R/LFE to stereo other than Handbreak Handbreak is great and love it just takes a while and some times i feel as if the video quality goes down.
Thanks!
I use ripbot264 and make a copy of all my Bluray Rips to 720p w/5.1 audio for use on my phone. It gives you LOTS of options for improving video quality etc.

Video quality is going to go down no matter what you use b/c of the huge drop in bitrate as well as drop in resolution. As far as taking too long, I think that depends on your system.

Why not make them 800x480 (or somewhere around those numbers to maintain aspect ratio) since phone can't do 1280x720 and you're pretty much just wasting storage space doing 720p?

but it wont play 5.1, haven't tried it with 5.1 headphones yet however it wont play out the external speaker or in headphones unless its stereo. Or am i missing an option on my Vibrant somewhere?
I would like to know why you can't pause a movie and return to the same spot. It starts from the beginning every time. Is there a trick or just the way it is?
@krichek it wont play 5.1 out of the external speakers correct?

Are you asking if the file will play at all? Or if it sounds like it's in 5.1 through the external speaker?
It will play files with 5.1 but I don't think they sound any different if you are using the external speaker. I think they sound slightly better than stereo using the headphones tho.
As to why I encode in 720p with 5.1, I plan on purchasing the USB-HDMI cable when it is released and want to be able to play them on a monitor/HDTV without having to have 2 different versions on the phone.

Ok first follow this tutorial to get your audio out of the video file.
Next use Headac3he to downconvert the file from 5.1 to 2.0. When the program is loaded you will see an option button on the main window. Click it and then it will pop up a second window. At the bottom you will see the down conversion settings. Set it to 2.0 and let it convert.
Then mp3 the wave file and use virtualdub to plop the audio file back into the video file. I'm sure you can find tutorials for all that. If you need to learn how to use any of the programs above tutorials can be easily found on your favorite search engine. Once you learn what your doing here this will take less 7min per file to accomplish.
Dang..... azid.dll cant download it from the official site looks like the site no longer exists. this is for Headac3he
Edit: Attempting foobar2000 as recommended by an IRC friend.

??? I was able to download it from here . It's right under the download link for headac3he
Also I don't see how foobar200 could do any conversion since it's a media player.
