kalimutu,<br><br>r u transcoding the video or it is a direct record from a 3g phone. If It's direct record, as Dan suggested, it depends on the encoding capabilities of each phone. If the encoding is hardware based, you can't do much. One other thing I've found is that whe I do phone to phone video calls, quality is great, but if you do the H.245 negotiation and try to record to your device, then quality suffers.<br>

<div>Hi all,</div>
<div> </div>
<div>I am exploring options on how to improve the H324M/3G video calls recording quality. I have tried updating the libh324m/app_mp4/mpeg4ip/ffmpeg to the latest SVN revision but there seems to be no improvement. Another way I have tried to improve the video quality is to change the video bitrate (from 52kbps H263+12.2kbps AMR to 60kbps H263+4kbps AMR) in H245Capabilities but there isn't much significant improvement on video quality eventhough audio quality is lowered.</div>
<div> </div>
<div>Just wondering if anyone can suggest any solution/findings on this recording video quality issue? I have also uploaded a recorded sample to <a href="http://www.sendspace.com/file/lvwon0" target="_blank">http://www.sendspace.com/file/lvwon0</a> in case if it is useful for comparion/benchmark purpose. Thank you.</div>
<div> </div>
<div>Regards,</div>
