Audio solution...?
While patiently counting down to next week's NAB show, the more I read up on the missing & crippled features on the 5D, the more my expectations recede that we'll ever see Canon fixing the 5D's shortcomings, (I even tried to design a bypass device for the AGC using a dog-trainer's subsonic oscillator..).
So, I've now more or less thrown in the towel as I'm about to get this recorder H4n Handy Recorder and use its line-outputs to feed the 5D as a guide-track and then "clapperboard" sync it for the real recording in post. However, I still would immensly appreciate it if someone could talk me out of this, (with a good/sane reason, of course -- or better yet, come up with a better solution). -- peer

Beacktek Device for 5D
Have you checked out the Beachtek device coming out at the end of May?

Peer: Do not buy a Zoom recorder, there's many well documented issues with the sync of the device.
We bought the regular H4 for our 5d mark II, and I just found out about the syncing problems. With everything 20 minutes, it is 3 seconds too slow. Now, the audio is really great on it, but these syncing problems makes it largely useless for video. The issues seems to be the internal time/clock in the recorder, and again it's widely documented. |

Are you sure that the sync issue is still present with the H4n?

No not at all... sounds like they fixed it, but the issue was there on both the h2 and h4, so I just wanted to warn Peer, that Zoom isn't exactly the safe bet. But hopefully they fixed the problem with the h4n, it looks like it.
Personally I would just be really sure that the H4N is a-okay :) |

I use the Zoom H4N to sync with my 5d with no problems. To be fair, my clips are rarely more than 10 mins long so I can't speak to how it may move out of sync over longer periods. I am currently using it to record dialog for a TV show pilot but the individual scenes are short.

I have the Zoom H4 and have not had any sync problems with the 5D2. I am using Final Cut Pro, transcoding the 5D2 footage to 720p30 (29.97), recording the audio on the Zoom H4 as a wave file using 48 Khz and 16-bit recording, and then transcoding the audio to AIFF (keeping it 48 Khz and 16-bit). I previously had sync issues when I was recording at 44 Khz instead of 48 Khz. With my current workflow, my sync has been VERY good. Hope this helps. But I have a feeling that sync issues are EXTREMELY complicated and can arise anywhere from the recorder settings, transcode settings, video edit software, etc...

I bought a Zoom H4 (right before the H4n came out) in order to help record audio with a 5d that I plan on buying. This stuff about video being usuable worries me ...to say the least. I don't want useless video.
Does anyone have any tips or advice? I can try to sell my H4 and buy the H4n, or if anyone has a description of steps for syncing things with the H4 that'd be great. (David's description is great, but I don't use Final Cut and I wonder if that makes a difference.) Thanks. |

If you use Vegas, it's really easy to stretch/squeeze the audio to match the video. Get the start of the clip sync'd. Check the end of the clip. If not sync'd, hold the Ctrl key and drag/drop the end of your audio clip as needed.
