Change quality for mp4

[losqut]

Hi all,
I use the Vrex example from nokia forum for record video from on board N81 camera.
And I need to change the quality to high for my recorded the mp4 files.
On the forum I found one solution:

_LIT8(videoType, "video/mp4v-es; profile-level-id=3")
CVideoRecorderUtility* iUtility;
.....
iUtility->OpenFileL(filePath, aCameraHandle, iControllerUid, iFormatUid, videoType, 0x43414120);

But the quality is about 74 kbit/s although from my native camera application the quality is about 394kbit/s .

iControllerUid and iFormatUid I select like this:

.........
_LIT8(KFileExtention,".mp4");
.......
// Resolve the supported video format and retrieve a list of controllers
CMMFControllerPluginSelectionParameters* cSelect =
	CMMFControllerPluginSelectionParameters::NewLC();
CMMFFormatSelectionParameters* fSelect =
	CMMFFormatSelectionParameters::NewLC();

// Set the play and record format selection parameters to be blank.
// Format support is only retrieved if requested.
cSelect->SetRequiredPlayFormatSupportL(*fSelect);
cSelect->SetRequiredRecordFormatSupportL(*fSelect);

// Set the media ids
RArray<TUid> mediaIds;
CleanupClosePushL(mediaIds);
User::LeaveIfError(mediaIds.Append(KUidMediaTypeVideo));
// Get plugins that support at least video
cSelect->SetMediaIdsL(mediaIds,
	CMMFPluginSelectionParameters::EAllowOtherMediaIds);
cSelect->SetPreferredSupplierL(KNullDesC,
	CMMFPluginSelectionParameters::EPreferredSupplierPluginsFirstInList);

// Array to hold all the controllers support the match data
RMMFControllerImplInfoArray controllers;
CleanupResetAndDestroyPushL(controllers);
cSelect->ListImplementationsL(controllers);

TBool recordingSupported = EFalse;
for (TInt i = 0; i < controllers.Count(); ++i)
{
  RMMFFormatImplInfoArray recordFormats = controllers[i]->RecordFormats();
  iControllerUid = controllers[i]->Uid();
  for (TInt j = 0; j < recordFormats.Count(); ++j)
  {
	if (recordFormats[j]->SupportsFileExtension(KFileExtention))
	{
	  iFormatUid = recordFormats[j]->Uid();			
	  recordingSupported = ETrue;
	  break;
	}			
  }
  if (recordingSupported)
  {
    break;
  }
}

CleanupStack::PopAndDestroy(&controllers);
CleanupStack::PopAndDestroy(&mediaIds);
CleanupStack::PopAndDestroy(fSelect);
CleanupStack::PopAndDestroy(cSelect);
