    Is there an "Exception" list for MC?

    One transcoded audio file (transcoded from .mp3) is giving me the following "Exception" (in the Console) when I try to show the waveform on either track of dual mono.

    Exception occurred during waveform drawing - what: CORE_PTR_IS_NULL xcode: CORE_PTR_IS_NULL expandStr: Exception: CORE_PTR_IS_NULL, className:WaveformCache.c, methodName:BuildWaveformSourceRefUID, pointerName:itsTrkGrp

    Does anyone know what this means? I have cleared cache and tried different waveform display settings. Trying to display waveform on the original .mp3 gives me this message:

    Exception occurred during waveform drawing - what: CORE_PTR_IS_NULL xcode: CORE_PTR_IS_NULL expandStr: Exception: CORE_PTR_IS_NULL, className:WaveformCache.c, methodName:BuildWaveformSourceRefUID, pointerName:itsTrkGrpWarning: 2 audio clips required Audio SampleRate Conversion.

     

    Please convert these files to avoid underruns and improve audio quality.


    Thank you for any thoughts you might have.

    If you convert the sample rates does the waveform display?

    {edited to add} But wait to see what Jeffrey Lomicka says on your Facebook post before you try anything else.

    Thank you for the suggestion. The .mp3 is 44.1 kHz and while transcoding, the sample rate was converted. The "new" file is 48 kHz. No waveforms in either. I noticed MC is using the Quicktime plug-in to play back the .mp3. I'll wait for Jeffrey lomicka's response.
