thank you for all your great answers. Really helping me in understandig this topic. I used the last few hours to try out the timecode workaround, respectively using a spare audiotrack to record smpte on it...the same procedure with my DSLR Canon 500D. Timecode Master was the iPhone App "TC Toolbox" from Denecke (just for testing)
So for those among you who are interested in it this was a little bit of tinkering with adapters:
Downloaded the app from the itunes app store for free. Plugged a y-cable headphone plug into the iphone.
Attached my sennheiser 416 (track1) as well as the timecode (track3) to the edirol r44 mobile recorder. The other end of the y cable was plugged into the audio input of the dslr camera. Recorded 10 seconds as a test.
After impoting the files to the computer I looked for a software that merges my audio timecode (AUX TC) with the actual audio file to a BWF. Got to find that little piece of software: VideoToolShed - FCP auxTC reader
Immedietely downloaded the demo which runs in full function but only exporting the files within 10 seconds length. There are 3 apps in this application package. I've been reading through the manuals but didn't get a clue how to manage getting a accurate BWF File and how to get the Audiotimecode of the Video written into the Videofile.
The timecode ist correct and the application is able to read it=)
Will check this the next time. Thats just a report what happened until now. Will keep you informed. Has anybody got experience in using the AUXTimecode Application tool?
