Joel,
Yep, been getting that problem over here both at 25 FPS & 30 FPS on Canon 5D Mk II. Really noticed this about March this year – maybe a Canon Firmware issue. Anyway, always seems to be out about 2 Frames – audio early – it must be something to do with the video codec processing and data writing etc that produces the delay.
So, always worked around this by syncing external audio clap to the video – difficult on some of the material as it was ‘synced’ on location with a hand clap, which was often blurry. Haven’t bothered with Plura Eyes in FCP 7 yet, as I’ve just done it the old fashioned way manually.
Tried with FCP X and it syncs up the external audio all automatically and really quickly. As expected the new sun clip is also 2 frames out, but i simply used the “break apart clip items to show the external audio and then selected ‘detach audio’ to separate out the original linked camera guide audio from the video. The V key then enables or disables the tracks – like mute/make visible tc. Then a simple two frame nudge with the ‘period’ ky and evything is in perfect sync. BTW, if you didn’t know already the ‘period’ or ‘full-stop’ (UK) key nudges the selected clip one frame forward and the ‘comma’ key one frame back.
It’d be really good if this frame offset could be entered numerically as an option in the synchronisation settings of FCP X. At the moment it’s just a global command without any parameters Is it an option in Plural Eyes for FCP 7?
Hope this helps.
Hope this helps
