Thank you John, put the audio through Wave Agent, changed the frame rate and it worked!! Life saver.

Thanks Andrew. I decided to go through and manually cut and re-sync the audio, but this is helpful to know. I’ll certainly test it out, but for now, no more H4N with 25 fps video!

Thanks for your response. From what I’ve read from people complaining about H4N drift online, it seems to be no more than a 7-frame drift in most cases, and that is around the 10th minute. I’m seeing significant drift at minute 1.
The clip is a 13-minute interview that does not require cuts, and I have several others of a similar length to sync up. I’d rather not have to go through the entire project cutting at :45 second intervals and re-syncing. I’ll do what I have to do, but surely if I’m not the first person to experience this, there must be a work around with timeline settings.
If anyone out there has a solution, I am all ears!

“The camera was set at 48kHz/24-bit, as was the H4N.” <—- That is what I MEAN. 48 kHz/24 bit was the setting on the H4N.
Below is a screenshot of the audio settings, notice the TC Rate is 24 here:
And these are the settings of my VIDEO, the TC Rate is 25 here:
At the 1 minute mark it begins to drift slightly, and then is about 7 seconds off by the end of the 13 minute clip. I’m not sure how else to describe this to you.
I am not shooting with a DSLR, I shot on a Canon C100. The Canon was bought in Australia and the settings cannot be changed to shoot in 24 fps or any other NTSC format. I have not tried to sync audio with this camera previously.

Thanks for your reply. Yes, you’re correct – I’m using FCP and it is referring to the sample rate as a 24 TC rate. The camera was set at 48kHz/24-bit, as was the H4N. My FCP settings are 25p 48 kHz, I start to get audio drift around the 1 minute mark, it’s a 13 minute clip.
I know I’m probably not using the right lingo, but to your knowledge, is there anything I can do with the audio I have to convert it to a 25 fps rate?
