unlimited 3gp video recordeing - registery hack

I was messing with my jam today... and I got it to record in 3gp format to unlimited time or size
Do the following:
with any Registery Editor go to the Following Path:
HKEY_LOCAL_MACHINE \ SOFTWARE\HTC\camera\AppDefSettings\P3
then u should see a DWord Value called "EnableLimit"
change it from 1 to 0
now Soft Reset and Bingoo
Hope u like this tweek :wink:

thanks for the info.. i'll give it a try now
i thought there wasn't a timelimit on recording! the only limit is the size of the SD card that u record to!

there is no time limit for video recording
But if u want to capture video in 3gp format, u have to use MMS video... and this one is limited to 95 KB only.....
so u can capture 4-5 sec in 3gp
this hack disables the size limit
Greetings 8)

latest mms composer v2.0.0.13 sets 3gp record limit to 300kb. quiete resonable to send videos long about 32seconds.
Nice reg tweak.

thanks for the info duke..... keep up the good work

Does anyone know why my Magician changes to landscape mode if I set my camera to capture in 3gp format (H.263)? If it is set to Mpeg 4 there's no problem.

I have experienced the same thing. Obviously it's a huge bug, that has yet to be fixed after several ROM updates...

This hack has been included in version 3.8.0 of Tweaks2K2 .NET

Video Capture Encoder

Hi,
I developed and app for win.mob.6 for video capture live streaming using direct show filter. WMV9 encoder has very low performance of framerate no more 4 fps with lower res.
I am testing the app on HTC touch dual. I tried to enum all filters availables, but I found only WMV9 Encoder. The original app cam coder can create 3gp file with h263+amr-nb. I'd like to know how is possibile this !!! no h263 filter encoder are available.
I am looking for an htc WM5/6 model that can capture video frames encoded to 15 fps with a mid res 170x140.
help please.
thanks

Hi fala70,
I am sorry but I couldnt quite understand what it is your current status.
Have you developed the application and it is working or you would like to do it now?
What do you mean 'original' application. Are you based on an open source example or something?
Nice subject though!

This issue has been discussed quite a number of times (I asked the same thing a few months ago) but no resolution as come out so far. I think HTC does not allow its "private" encoders to be "enumerated".

My status it that I want understand if is possible to use an other codec encoder different from WMV9. WmV9 is too slow.

Video performance : THE SOLUTION !

It's not the ULTIMATE solution, but it's the only solution i found to watch videos perfectly in my Touch HD.
Video : HD trailer 800x480 @ 25 fps : Ice Age 2
Software : CorePlayer 1.2.5
First benchmark = 87%
First step :
Re-encoding the video in 240x400 on your PC with http://www.pocketdivxencoder.net/ or http://www.virtualdub.org/
Why 240x400 ?
- the video is pre-rotated (instead of 400x240) (performance +5%)
- the resolution is exactly the half of the native resolution (480x800) (performance +60%)
Second step :
Customize the options of Coreplayer :
Menu / Tools / Colors = Native
Menu / Tools / Preferences / Video / Video output = Raw FrameBuffer
Menu / Tools / Preferences / Video / Smooth zoom = OFF
Menu / Tools / Preferences / Video / Dither = OFF (uncheck)
Menu / Tools / Preferences / Advanced / Slow video memory = check
Results (the quality of theses videos seem egal)
800x480 : 87%
800x480 (with the options) : 95%
240x400 : 141%
240x400 (with the options) : 232%

Any visible degradation on picture charity and details?
Would be good if you post both clips for all to see for themselves.
Beautiful work. Thanks.

no, the quality seems the same
because the DPI screen is very high (800x480 for 3''8)

Sorry are you saying we have to re-encode a hi res video ourselves (on a pc) to half the resolution (step 1) or does the player do it automatically?

I upload the trailer "Ice Age 2 HD" on rapidshare (ready in 15min) :
800x480 3Mbits : 26 Mo
240x400 3Mbits : 13 Mo

Re-encode on your PC !!
With PocketDivxEncoder for example Very easy to use !

OK, the upload on Rapidshare is done :

You have 2 files : the original, and the optimized 240x400
BUT YOU NEED TO change the options on CorePlayer (see the 1st post of this topic) to see the result.
Default options :
800x480 : 87%
240x400 : 141%
With the optimized options :
800x480 : 95%
240x400 : 232% !!!

Good post. I think our moderator should sticky this.

Well I got to that solution a week ago, when I got my Touch HD.
But the Coreplayer options, I didn't knew.
Simpy using pocketdivxencoder is enough for me.
But thanks!
Cheers.

Nice solution...
The only problem many of us expecting the Touch HD to have good video performance without the hassles of re-encoding videos.

You can't really expect the phone to resize every frame of a massive video eg 800 x 480 or whatever on the fly. If you want better results, of course you have to re-encode yourself to a more suitable size. Otherwise it's just wasting CPU usage and you'll definitely get slow downs.

Sorry but this doesnt sould like a solution to me. Its just reencoding a file to a extreme low res, only a fourth of the pixels, and playing it.. Of course it plays ok, but its only 240x400, and besides that, its completely unpractical to reencode every moviefile. So: nothing changed, no solution at all...

What video bitrate and audio bitrate did you use in pocketdivxencoder to resize your video?
In the advanced options did you choose your ppc as portrait or landscape?
Finally, I can only resize at 400x240. How could you resize at 240x400?
Thanks!

oh yes, what a super duper solution, re-encode the video with less quality on a pc and losing time.
HTC should contract you for new developments.
This is not a solution, the only solution is get hardware acceleration and software allowed to use it.

Guys,
If there is no noticeable degradation in picture quality and sharpness (which was my question in my post), why are you having problem with this solution? Why carry along and process all the 7.1 sound system when you only have stereo capability? Why carry along all the resolution of a blueray when you don't need it? Of course it is reasonable to go through some processing and bring it to a form that we need, minus all the unwanted and unnecessary stuff if that provides the same clarity and improves performance.
Is the reduced resolution becoming ****ty? If it is, then all the phones out there with such resolution (includinding the most worshipped iPhone) ought to be thrown in the bin too as a meda device.
Millenius, thanks for all your tips. It is definitely helpful.

I agree, although the proposal is offered as a solution I would say it's a clunky and expensive workround....but thanks for sharing for those who maybe already have the Coreplayer software. [1]
My Archos (heaven forbid I am going to say something positive about it) just does it .... screen is the same resolution. I drop a 700Mb file and it plays.
I do not know the difference in the internals but it is a disappointment because I was hoping to reduce down to a single device .... looks like the Archos has some life left in it yet.

Yes, HTC should supply the video acceleration drivers...no doubt. However, there aren't many portable devices that can take a high res movie that is meant for a PC and play it perfectly. Another example, would you take a 12 mega-pixel image that you took from your DSLR and just download it to your HD for viewing...of course not, you would re-size it first to save disk space, knowing that the extra resolution is wasted on a screen that size anyway. It is a hassle, but worth the trouble.

I dont know much about video resolutions and such, just want to be able to watch Divx TV series on my HD. And at this the HD did just fine - until I tried the settings recommended in the 1st post. Then I had a noticeable lag, and between every scene it felt like someone turned a page - black frame(s) - or turning a curtain, dont know how to explain otherwise. Got rid of all the changes, except Colour, and cannot check Dither again. Any idea?

[HELP]Problem playing videos recorded with the camera

Hello, i've a big problem :
When i record a video with my camera, and i want to see it with the stock player, the video stay black and sound do " ssscccrrrr ".
But if i open the video with tcpmp, no matter.
If i put the video on my pc, with vlc, no matter.
I've tried all configuration of format to recording (MPEG4, ...), and i put off my SD card, to recording on the phone directly, it's the same way.
Why i can't play my video with the player, even on photo's tab ?
It is a codec problem? where find them ?
Thanks for your answer.

This also happens to me when I record video longer than 8 minutes/larger than 250MB. I have set the recording quality by the hints in the stickie topic here.

Even with a short video, i've the same problem, but how to set the quality recording ?
I've tried different tweaks to increase the quality, or more recording quality with Bs tweaks or XT hack beta 2, and i can't play the video ?!
I stay to think that is a codec's matter, because i can play it on my pc with vlc.

I used this tip:
63. Unlock Additional Video Recording Formats
Go to HKLM\Software\HTC\Camera\P2 and replace the EncodeFormat value with 2147483647
This will unlock all modes/resolutions listed below:
H263(3gp): CIF 352x288 \ M 176x144
MPEG4: L 320x240 \ CIF 352x288 \ VGA 640x480
3GPP2: S 128x96 \ M 176x144 \ L 320x240 \ CIF 352x288 \ VGA 640x480
MOTION JPEG: S 128x96 \ M 176x144 \ L 320x240 \ CIF 352x288 \ VGA 640x480
H264: L 320x240 \ CIF 352x288
now I have set following on my Leo:
Resolution: CIF (352x288)
Capture Format: MPEG4

Thanks for your reply, i've tried your tips, then i've few recording format, i set them like you, but when i take my video, eveythink is ok, but after took it, i want to see it, but i can't ...(with tcpmp it's ok but not with the stock player)
French stock rom Orange
ROM: 1.43.73.1
RADIO: 2.04.50.22_2

well, I cannot help you any more. I don't even know, if there are any codecs for WM devices...
maybe someone else can help? I would also like to get info why I can't record vids longer/larger than 8minutes/250MB. I actually can, but can't play it on Leo, nor the PC (VLC, Media Player Classic...).

Nobody have an idea about WM codecs ?

Video recording not working in 640x480

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.

Best regards to all,

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.
