    Audio Export - Bad Quality

    Hi,

    it's days now and i can't figure it out. When playing back my sequence with music audio in timeline audio is fantastic. After exporting my sequence audio is always of bad quality. Export Setting is QT h264and at first i tryied with AAC compression than without any sort of compression (didn't select audio in otions) but same result. I've tried with the two mono channel and then with one stereo channel and same result.

    Anyone can help me or have an idea why this is happening?

    Which specific version of Media Composer are you using? What are your system specifications? When you say "bad quality" what do you mean?

    Re: Audio Export - Bad Quality

    I'm using 8.4.5 on a Mac.

    When listening in the timeline, audio is good like original file. Exporting, is like if sound is lower and the low frequencies are almost gone

    Here file .mov with just audio

    Re: Audio Export - Bad Quality

    The track seems, as you say, fine in stereo, however as the piano in the recording has a lot of out of phase elements, it reduces the level of the piano if you mono the track.

    Perhaps, as Pat says, something in the export chain is summing the tracks, this would cause the change in balance and would certainly add some distortion as both channels peak at "0".

    Re: Audio Export - Bad Quality

    So what should i do? Why the piano in timeline sounds perfect and than came out distorted? 

    When exporting i select qt reference and only audio, in preference i don't flag audio setting so it should came out without compression i suppose?!

    anything wrong here?

    Re: Audio Export - Bad Quality

    The file i AMA linked is an mp3. I realized every audio file i import have the same behaviour.

    Checking the console it says: MSMRescan() took: 0.171837s

    p, li { white-space: pre-wrap; }

    Warning: 1 audio clips required Audio SampleRate Conversion.

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

    Can you post a screen shot of your timeline? It might help if we could see the sequence.

    Re: Audio Export - Bad Quality

    i've just tried duplicating sequence and leave just audio file. The audio original file is 44100Hz so i set project format at same Hz and now console says: 

    Audio Mixdown will require 42893396 bytes. AudioSamplesInSequence= 10723349, SequenceLength= 5830, DestinationBytesPerSample= 2, numOutputChannels= 2. 41888 KB needed.

    p, li { white-space: pre-wrap; }

    Duplicate definition entry (not added)

    Plugin definition registration failed

    Re: Audio Export - Bad Quality

    Have you tried to do a audio mixdown and if as you say no L/F then that could be a phase issue I always do mix downs befor encoding

    You may be on to something about the mp3. I downloaded the audio and this happened:

    1. I heard the volume you spoke of while it played in the MC timeline. Also there was a glitch @ 1:51

    2. The (wave file) exported from MC had much lower volume

    3. When exported as the other option (not aiff but somethinge else. Not on that computer with MC 8.8.0 at the moment) there was silence.

    4. When sending the original file out as an aaf there was an problem trying to import it into Davinci 12.5.6.

    5. The wave file that was exported from MC (low volume) imported into Davinci as a mono file.

    6. I did not boot into the OS that has all the music/audio apps to manipulate the file

    So you say the mp3 it's the problem? I've tried with other 4 songs (mp3) and same result.

    Yes, i've tried but same result. What you mean with no L/F

    When you do a mixdown you send new audio in a new track right, and what you do with the tracks you have mixed down that remain in timeline?
