Issue with audio out of sync after interpolating #259

Hi, the attached video when run with an output to 60FPS isn't aligning the audio correctly, not sure why this is.

The video isn't a fixed 30FPS or NTSC source, it's an odd frame rate of 28.89, but renders to 60fps fine using flowframes, only the audio goes off after doing this. The best reference after rendering to 60FPS is at 8min 15 sec mark, it's about 5 seconds off at this point.

I'm using the latest Patreon version 1.40.0. I've spoken to you before on Reddit but since it's not game related, I thought it would be more relevant to mention it here instead, I hope that's ok.

Thank you :)

It looks like it's the video that is the issue, not the audio. Both match up audio wise, but the video is changing. The source is the correct timing, but not the output.
