  1. Hi,

    I have several AAC files that play fine outside of Vegas Pro (16.0) but once I play them in Vegas to edit they keep jumping a few seconds ahead, they're completely choppy.
    Does anyone know what could be wrong and how to fix it?

    I did convert a few of those files to mp3 and that resolves the issue, but I'd prefer to use the AAC files.

    Thank you.

  2. If problem loading files and quality is at stake, lossless or almost lossless formats are used to load it into Vegas. That's a general answer. Vegas has general problem loading elementary streams.

    One workaround for Vegas though is to use a proper container for that elementary stream. So using intermediate wav or muxing that AAC into a mp4 or something else might help.

    I wouldn't know how to do that.

  4. I didn't mention that those AAC files are extracted from MKV files. I used mkvcleaver or FFMPEG to extract them, but they had issues in Vegas in both cases.

    Here's the details:

    Audio
    Format : AAC
    Format/Info : Advanced Audio Codec
    Format version : Version 4
    Format profile : HE-AAC / LC
    Bit rate mode : Variable
    Channel(s) : 2 channels
    Channel positions : Front: L R
    Sampling rate : 48.0 kHz / 24.0 kHz
    Frame rate : 23.438 FPS (1024 SPF)
    Compression mode : Lossy
    Stream size : 31.2 MiB (100%)

    Is the HE-AAC format the issue maybe?

    Open them in Audacity (with the FFmpeg helper installed) export as WAV and use those.
    Uncompressed WAV/PCM should always be accepted.

    Why would you convert to mp3 and suffer another generation quality loss?

  6. Thanks I'll try that.

    The mp3 thing was just to check if the format fixed the issue or not.
