it's because AME caches settings of prior jobs. I noticed this too. it doesn't run exSDKGenerateDefaultParams(), only exSDKPostProcessParams(). So, you never had the code run that set the max, min etc.
In exSDKPostProcessParams you need to read every parameter and than fix all the fields - the only thing you can trust is .value, all the others like .maxrange.value, .minrange.value .hidden, .disabled, etc are potentially corrupted so you need to fix them and write them back (ChangeParam())
eg: This is my Frame Rate code in exSDKPostProcessParams. I setup the string labels but more importantly I read, fix and write the frameRateValues structure.
// --------------------------
// "Frame Rate (fps)" [TEXT]: [DROPBOX]
copyConvertStringLiteralIntoUTF16(STR_FRAME_RATE, tempString);
lRec->exportParamSuite->SetParamName( postProcessParamsRecP->exporterPluginID,
0,
ADBEVideoFPS,
tempString);
// Get the preset
lRec->exportParamSuite->GetParamValue(postProcessParamsRecP->exporter PluginID,
0,
ADBEVideoFPS,
&lRec->frameRateValues);
// Update local storage
lRec->frameRate = lRec->frameRateValues.value.timeValue;
lRec->frameFPS = (float)ticksPerSecond / (float)lRec->frameRate;
// Fix the broken fields (only trust "intValue")
lRec->frameRateValues.structVersion = 1;
lRec->frameRateValues.rangeMin.timeValue = 1;
lRec->timeSuite->GetTicksPerSecond (&lRec->frameRateValues.rangeMax.timeValue);
lRec->frameRateValues.disabled = kPrFalse;
lRec->frameRateValues.hidden = kPrFalse;
lRec->frameRateValues.optionalParamEnabled = kPrFalse;
// Write back to AME preset storage
lRec->exportParamSuite->ChangeParam(postProcessParamsRecP->exporterPl uginID,
0,
ADBEVideoFPS,
&lRec->frameRateValues);
// FRAMES PER SECOND DROP BOX VALUES
lRec->exportParamSuite->ClearConstrainedValues( postProcessParamsRecP->exporterPluginID,
0,
ADBEVideoFPS);
for (int i = 0; i < sizeof(frameRates) / sizeof (PrTime); i++)
{
tempValue.timeValue = frameRates[i];
copyConvertStringLiteralIntoUTF16( (wchar_t *)frameRateStrings[i], tempString);
lRec->exportParamSuite->AddConstrainedValuePair( postProcessParamsRecP->exporterPluginID,
0,
ADBEVideoFPS,
&tempValue,
tempString);
}
