Hi Steve,

Thanks for posting this. I tried using this method, but for some reason the subtitles don’t actually show up when I bring them into Premiere Pro. Any suggestions on why this might be, or what I can do?

thanks,

Sabreena

I have an update to share, but still am trying to figure this out. I realized that the audio recorded on the zoom recorder is at 44.1 kHz, and the audio for the 5D footage is at 48 kHz. Now I have tried converting the audio to 48 kHz through FCP and through compressor, but it didn’t seem to work. I actually pulled the supposedly converted track into FCP and compared it with the original 44.1 version and they matched up with each other, so it doesn’t seem that the sample rate is actually being changed. The interesting thing, however, is that I when I tried converting the clip from the 5D to 44.1 kHz, (converting the guide track to match the recorded audio versus converting the audio to match the guide track) everything ended up syncing up. I feel like converting all the video I have though will end up taking way longer and take up more space, and just intuitively feels wrong. I feel like there has to be a solution somewhere to get the recorded audio in sync with the audio from the 5D, I just can’t totally figure out how to get the clip to up-convert properly, so that it actually runs at 48 kHz. Any ideas?

Hey Joel,

We used the H4 model of the Zoom recorder, and we shot at 24 (23.98 fps). I’m editing with Final Cut 7. I’m not totally sure what firmware is on the 5D,. but I’m guessing that it’s 2.0.4 since FCP shows the framerate as 23.98fps.

I have tried changing my audio speed, but without success.

I’ve uploaded one of the files I’m working with if you want to try taking a look at the elements (I figure it’s easier to troubleshoot when you have access to the file)

you can find the guide track here: https://f1.creativecow.net/3578/guide-track

The AIF version of the track, converted to 48 kHz is here: https://f1.creativecow.net/3580/recorded-audio-aif-version

The WAV version of the track at 48 kHz is here: https://f1.creativecow.net/3579/recorded-audio-original

Let me know if you’re able to figure anything out, because I just can’t seem to.

Thanks

Hey,
I’m having a huge issue with syncing sound that I recorded with a Zoom audio recorder and a 5D. I can sync the guide track and the audio together at the beginning, but there is a drift so that by the end of the clip the recorder audio is abotu half a second off from the guide track. I’ve tried the easy setup fix, and have tried converting the video to prores, and have had no luck. Any suggestions?

Tried converting the 5D files to ProRes 422, and I’m still having the sync issue.

I’ve uploaded the guide track and recorded audio versions of one of the tracks that I’m working with if anyone wants to play around with them. I figure it’s easier to trouble shoot when you can actually manipulate the files, rather than just thinking about them.

Here is the Guide Track: 3578_guidetrack12.aif.zip

Here is the Audio from the Zoom recorder as a WAV file: 3579_recordedaudiooriginal.wav.zip

Here is the Audio from the Zoom recorder converted to an AIF file: 3580_recordedaudio12converted.aif.zip

Please let me know if you have any suggestions. I’ve tried even changing the speed slightly, and it still won’t sync up.

I’m having this issue too. I shot some footage on a 5D and recorded the audio to a Zoom recorder, as well as to the camera mic, in order to have a guide track, i’ve tried following the steps mentioned, but it is still drifting. Are there any other suggestions on what I can do, or alternative ways of fixing this?

Thank you

I’m not totally sure, but I think what happened before is that I wasn’t highlighting the files before I selected “use item in and out.” I just got it to work. Thanks so much for your help!

[Sabreena Pe]

sorry about that. Try this one:

Yeah, that probably should work, but for some reason it isn’t for me. I took a screen shot so you can see better what’s happening, incase I’m doing something wrong.

As you’ll see, there are the original clips that have been dragged from the timeline, and then there are the clips labeled with “copy” which are the duplicate masters. In the Batch export window, they still all show up as the same length. Thoughts?

[Sabreena Pe]

I did that… for some reason it still ends up exporting the while file. 🙁
