Did is possible setup better bitrate in HD recording??
Now is 32kbps,voice is poor,will be cool if can be setup to 128kbps,
Any one know trick to do that???????
I check in 800x480 audio have a 64kbps....

I recorded a short clip of my voice with HTC's Voice recorder app. Then i went and downloaded TapeMachine Lite from the market. WOW what a difference. I always thought the DHD's poor audio recording was down to hardware, but clearly not. HTC for some reason set the audio output to 8000Khz, but TapeRecorder records at 44.1Khz or 48Khz, in a format of your choice (WAV is default).
So i was wondering, how easy would it be to implement this quality recording in the camcorder app? If someone does this then i'll happily shell out some money for the cause.
I just repeated what you've just posted. Wow, what a difference. Why this isn't default on the DHD camcorder I don't know.
I think the sample rate in the camcorder is a limitation of the audio codec that is used, just guessing tho as I'm not sure of the all the limitations with aac-lc
Sent from my Desire HD using XDA App
no the camera 720p encoding is AVC h264 with AAC audio, the standard is baseline L3.1 and based on this standard the audio should be encoded at 44khz 160kb bitrate
8khz is just one of those amazingly stupid things HTC keeps on slipping in, i don't know if its done to lower the stress on the recording frame rate
i sent them an enraged email about this a while ago and all they said that its passed on to the accurate department
but with 8khz i was surprised at the loudness of the recording, which explains your post today
can someone fix it with a patch? and while at it, please increase the screen red saturation a little
Hi guys,
I'm curious how to encode a video for playback on SG3 to achieve best visual and audio output and keep the lowest battery consumption. So, what do you recommend:
Video:
resolution
codec
fps
bit rate
etc
Audio:
codec
sample rate
bit rate
CBR / VBR
etc
SG3 display resolution is 240x400 but I found on official samsung site that (best or recommended or ?) resolution for playback is 720x480.
Thx for any advice
Resolution/codec/bitrate: SD (720x480 or less)
- if you download an XVID film or series (and the size doesn't matter) you can directly play it from inbuilt media player.
Audio: I suggest MP3 CBR 320kpbs, or MP4A VBR at highest quality, MP4 produces better quality and supported by most popular media players.
Codec:
xvid - good quality, and less CPU usage
h264 - good quality, smaller size, but more cpu usage.
FPS: use the source values (if your movie is 25fps and want to convert to reduce size etc. use 25 fps)
Bit-rate: depends on SD-card speed, most of XVID movies are @1000 kbps, maximally use 1500 kbps I think it's enough.
Sample Rate: 44100 Hz is standard CD quality, 48000 Hz is DVD quality, I think you will not hear any difference.
Hi everybody. I am running Phiremod 6.2. What I really want is to be able to drop a standard definition video on the sd card, such as a divx or xvid file on the and have it play back smoothly on the nook. It seems that hardware video decryption doesn't work and that is the reason we are stuck using software decryption. What is the best video player? Even with the best video player, do you still need to re-encode the videos to lower resolution for proper playback? What format do you re-encode video to? Do we expect hardware video decryption to be accomplished by the amazing xda hackers?
Thanks!
I use Mobo player for playback. Have encoded several standard def videos from a TV series using Handbrake with the nookcolor preferences created by someone else on this forum, in H.264 format. They look and sound very good this way, except it does not fill the screen which is expected as it is standard def. Have not tried any HD content yet.

Isn't Phiremod just a modded CM7? CM7 suppports hardware decoding, for up to 480p files (max 854x480). Anything beyond that will be soft decoded. Anything that isn't expressly supported by Nook's "supported" video/audio formats are, afaik, also software decoded (the base player will not do this, need something like vitalplayer or rockplayer, etc.)
- If a video is just not a supported format but is 480p and under, it runs very smoothly for me in CM7 as software decoded -- you wouldn't be able to tell that it wasn't hardware accelerated.
- If a video is higher than 480p (720p, etc) or the bitrate is too high, even if it is the supported format, it will also attempt to be software decoded. My experience with this is that it's poor quality (stutters, audio desync a lot of times, etc.)
MP4 container, H.264 baseline codec for video conversion. Anamorphic loose, 854x480. AAC / MP3 (I forget what else is supported) codecs for audio, choose 44.1 khz sampling rate instead of 48khz to avoid problems. Bitrate for video and audio are up to you, but I wouldn't use the lossless setting for H.264 because you'll have issues with it playing (and will be an enormous file). You also really don't need to use it for a 7" screen. For me, video bitrate of 800 kbps (avg) is low but acceptable, 1100 for medium, 1500 is (non-HD) dvd quality. 128-160 kbps audio, your choice.
There's a lot of players out on the market, many free. I like Vital Player Neon a lot but the paid app version failed on me because of their self-copy protection. I use Moboplayer and also installed the Neon codec from the dev's website, it improved my performance noticeably on some more system-intensive videos.
As always, YMMV.

Is the <-> (vs >-<, etc options) not working for you to expand it to full screen? I have not had any issues getting 480p content to edge-to-edge (provided it's 16:9 aspect ratio, which many shows and movies are. While Nook's resolution isn't true 16:9 it's close enough that you won't notice any real edge). The only videos that display with bars for me are the wider aspect ratio ones.
(On stock rooted firmware, with 1.1Ghz OC)
I also use handbrake... encoding to 1024x576 xvid seems to do the trick with mobo player. (Altough so far I tried only one video file.)
edit: tried an other one, plays almost perfectly in sync. It is about 1 frame out-of-sync that can only be noticed with hard, fast sounds like slapping.
Encoding to h264 with the said resolution results in video being played back slower and of course audio being out of sync.
480p h264 baseline / aac mp4 files can be hardware decoded and play nice, but I'm all for the bigger resolution.

The ones I did were not in 16:9 aspect ratio, they were 4:3 which is why I believe I could not expand them to full screen. I haven't yet tried a 16:9 video like a movie but will soon.
in addition to the formats/resoluton mentioned try using Vital Player Neon - works with a lot of formats - plays really smooth on my NC (CM7 7.02+1.3GHzOC)
Thanks a bunch!
Using the video recording in 720p I have found that the fps of these videos is 24 fps.
Anyone else have a higher fps when recording in 720p and if we can record at higher fps in 720p recording mode?

question, why would you want to unless your looking for slow motion video playback?
in answer to your question, no you cant, the camera driver is the limiting factor, same reason we cant take wide screen photos
I'm using rooted official 2.3 rom. when I play mkv 720p movies , video plays at lower frame rate than usual and problem in audio video sync. I use mx player and hardware decoder is not available for mkv. can please anyone suggest me some tips to play 720p smoothly. and is there hardware decoding available in new adreno driver in dzo ics for mkv?
I m using bsplayer lite tha supports mkv.
720p on nearly 480p device?
Professionals can correct me, there are few reasons why it won't play in full speed:
1) .mkv files need usually the same space as .mp4, but it has better quality. BUT needs more power to play. That is the disadvantage of matroska. So if there is too high bitrate on the video, it lags/wents off sync. Overclocking might help.
2) 720p??! Really? This phone CAN record 720p video with good fps, but only in good light conditions. You can even watch them (because they are so low-bitrate), but if you have like 720p movie, it lags due to high bitrate it needs to look clear. BUT why would you want to play 1280x720 (16:9 ) resolution video in 800x480 (16:10) resolution screen? Shapes will look odd... I would prefer 480p (854x480).
3) I'm guessing that your movie is on your memorycard? If your memorycard is too slow, can that be the reason for lagging too. This can be fixed with faster memorycard.
4) Switch to Moboplayer. I don't have any experience of mxplayer, but Moboplayer can use hardware decoding for that.
