Previews are slightly out of sync...

[UnexpectedSwede]

Hello. I've just finished another AMV using my usual format finishing choice in codecs and quality. It's the same one I've used in past videos... but this time something's gone amiss in the site's preview conversion.

I say this because when I downloaded and double-checked it, the video was as it should have been. When I went to check the preview, I noticed that the music was slightly behind the video. Enough that, with it being an action video, it seemed off. I've not blatantly noticed this issue with any of my AMVs before.

Has something changed with the preview encoding? I'd rather not get dinged by people thinking that I made the whole video out-of-sync and that I didn't line anything up, you know? Any help and thoughts would be appreciated.

Restarting/searching through the video seems to re-sync it.
