I have a 23 minute long project on a DSLR 1080p 23.976 timeline that I want exported to a 720p .wmv file. When I tried this the audio on the exported video became slowly unsynchronized as the video went on, eventually getting to be nearly a full second or two out of sync.
When exporting a second time I changed the output frame rate from 24p to 23.976p. This got it slightly back in sync, but still noticeably off.
Is there something I'm missing? It can't be the change in resolution doing this, can it? Or is the .wmv format just not compatible with a DSLR timeline? Or... well, any ideas?
