audio static after AVISynth conversion/ld-chroma decode

[clashradio]

Hello,

I'm having an issue with audio after I convert using AVISynth. The new AVI's audio is static/white noise, yet the original MOV is fine.

I'm exporting a Domesday Duplicator-captured laserdisc TBC file using ld-chroma decoder, creating a mov. That mov is deinterlaced & upscaled with AVISynth. When I playback the AVISynth file, the audio is white noise. As a test I exported using TBC-Video-Export. That AVISynth's audio is fine.

I checked the two exported mov files in Media Info. Other than the TBC Video Export being 24-bit 44k (it should be 16/44) the only other difference is the Codec ID which says [in24] for TBC Video Export and [sowt] for ld-chroma decoder.

Do I need to add anything to my script due to this sowt codec?

Below is my script if it helps any.

Thanks for any suggestions.

v= LSmashVideoSource("input.mov",format="YUY2")
a= LSmashAudioSource("input.mov")
