The nature of this project involves using a variety of sources, most of which, unfortunately, are P & S 720p/1080i, and are meant to be synced to a higher-quality, separately recorded audio track. The attached audio tracks from the video sources, as well as the HQ audio track, are sampled at 44.1 KHz, which I have resampled now to 48 KHz, and am still receiving audio drift issues.

Is the Aud Format relevant in this issue? I noticed that my audio attached to my video sources, as with my sequence, have an Aud Rate of 32-bit Floating Point, whereas my separate audio source has an Aud Rate of 16-bit Integer.

Thanks Michael – I know for resampling my audio I can use QuickTime Pro or iTunes, is there a recommended (and hopefully expedient) way to resample the audio contained within my 29.97 fps AIC files?

Thanks Brian, I will run a full render and try and obtain an external monitor – on a 17″ MBP it’s pretty visibly off, but you never know. In any case I feel like it’d be a worthwhile investment… do you have any suggestions for a decent quality external monitor mainly to be used for projects such as these?

[Ben Silverstein]

Perfect, I’ll run the full render then. I will try and source an external monitor, as I can see where it would come in handy in terms of workflow. That said, it’s quite noticeable on the laptop screen that there is a sync issue by the end of the roughly four minute clip, when it’s spot on at the beginning.

Thanks Brian,

I just did a test – converted a video file from its original format to an Apple Intermediate Codec encoded (I hear that’s best for minimal rendering time) 29.97 fps file, and am still losing my sync unfortunately. You used the term fully rendered – I have no red bars above my video, but I do have grey bars, which according to the Sequence menu is ‘Rendered Proxy’. Is this rendered enough, or must I check off ‘Fully Render’ and let it work?
