Did a couple hours of dual-system interviews this weekend with the H4 and ran into the sync problems others have noted in the past - I got a steady drift of ~2 frames/minute across the board (24bit/96khz).

It wasn't a big deal but did affect workflow as I was under a pretty tight deadline. Normally I'd just merge the audio & video into a new clip (using FCP) but that wouldn't work here. I basically had to create a new sequence for each clip, sync the slate, then split the audio every minute and shift the remaining audio 2 frames forward.

This meant I had to edit with nested sequences which is a little more cumbersome - you have to drag from the project window to the viewer so the sequence doesn't open in a new tab, and you can't see audio waveforms on the nested clips.

With more time I think the workflow is to pre-calculate the exact drift rate, stretch the audio file by the correct percentage, and then use merge clips. I'm hoping this isn't an issue with the new H4n.

It is a little bit of a hassle to have 2 boxes but its a lot cheaper than the Sound Devices 702.
The Sony PCM-D50 does have an optional XLR input (powered).. but the option is not cheap... but you do get great results from either the XLR inputs or the builtin mikes...

I started another thread on this, but I though you audio gurus would like to hear and comment on this test using the Beachtek DXA-4 adapter. I uploaded this simple test.

Thoughts.

Sony | XLR-1 XLR Mic Adapter for PCM-D1 and PCM-D50 | XLR-1

Yeah the adapter is like $500 I looked at it but figured the mixpre preamps would be better
