Imported DV is missing sound

Using iMovie 10.1.8, I'm importing some old video from a Canon ZR25MC. The first challenge was with connectivity since I needed to get a Firewire400 to Firewire800 adapter, and a Firewire800 to Thunderbolt adapter. That seemed to work fine since iMovie is able to see and control the camera. Importing video worked fine except it is missing audio. When I enable "show waveforms" in iMovie the audio portion is completely empty.


I've tried two different Macs — an iMac and a MacBookPro, both running HighSierra and iMovie 10.


I've seem some mention online about Quicktime missing some codecs, but that was always in the context of importing compressed files. Here, I'm just trying to import raw DV straight from a camera.

Apple stopped listing specific model numbers of DV and HDV compatible camcorders some years ago.

They currently make a statement at the beginning of each manufacturers list for DV and HDV like this...

User uploaded file


Also the iMovie help says that DV and HDV formats are supported.

You are the second person in about a week to report that no audio accompanied the video

when importing DV and I believe they also were using High Sierra so this could be the reason.

You could try to import using QuickTime Player ( Record function)

Try a short test first and see if it plays back OK in QuickTime with audio.

If it does, import test piece into iMovie and see if audio is present.

The audio may still not import but may be worth a try.

It would be interesting to know if the recording using QTP,record function, does in fact include the audio.

Don't know what version of High Sierra you are on but version 10.13.2 was released

about 10 days ago, just in case this makes a difference.

New development...I've been sifting through old tapes all day, trying to import each one. Out of a dozen tapes, 1 tape actually worked, and I captured video and audio for it through FCPX. I have no idea what the difference is, and why it's just this single DV tape. I've attached screenshots of the file properties for some of the media from FCP. One is a file that didn't capture audio, and the other does have audio. They look identical though...User uploaded file

Hi, Joseph,


Your Canon ZR25MC is not listed as a supported camcorder on Apple's website. Here's the link where you can check it out in case I missed it:


iMovie supported cameras - Apple Support


That might explain why the sound is not importing. The audio might be in a codec not liked by iMovie. iMovie supports AAC (Advanced Audio Coding), aiff, Mp3, and Wav. AAC would be the one I would choose.


Instead of importing directly into iMovie, try importing the video to your desktop using the Image Capture app on your Mac. Then see if you can import it into iMovie from there. You can drag it into iMovie or use the iMovie import button. If it doesn't import, you might need first to convert the DV into Mp4/AAC. You can use the free download Handbrake to convert it by default.

Hi, Joseph,


The .dv may not have an audio codec that iMovie supports. Also, the Apple website doesn't list your camcorder as being a supported one, although if yours is tape based it may still be supported even if not listed.


iMovie supported cameras - Apple Support


Try importing to your desktop using the Image Capture app on your Mac, and then converting your .dv footage to Mp4/AAC. The AAC stands for Advanced Audio Coding. You can do the conversion with the free download Handbrake. After converting, drag the clips into iMovie and see if you get audio.


Another thing you can try after importing to your desktop, is to open and play the video in QuickTime Player. If you can hear audio, then save the vid, and that will give you a .mov file that you can drag into iMovie and see if it plays properly.

This is probably a long shot ,but thought it might be worth a mention.

Several posts in FCPX have talked of import problems since High Sierra 10.13.2 .

One or two concerning no audio when importing AVCHD and others with importing Mini DV in general.

The advice has been to uninstall Perian and A52.

I don't know much about these , only what I read in the posts.

The following is copy/paste of sections from 2 posts.

To uninstall Perian, I think you have two things to delete: the preference pane, and the Quicktime plugin.

And then RESTART your mac!

The preference pane is inside your Library folder: ~/Library/PreferencePanes

The Quicktime plugin is either in ~/Library/Quicktime or /Library/Quicktime.


Don't forget to RESTART.

Do you have Perian or A52 installed?

You may not realize it, as it may have been there for years.

Perian would appear in System Preferences, in the last row.

The A52 codec may be present in /Library/Quicktime or ~/Library/Quicktime.


Both of these are known to cause sound disappearing in AVCHD material.



Some posts say that removing Perian has cured their fault whilst others say that it hasn't, so this may not work for you, but worth a look to see if you have Perian or A52 .

I went back to using iMovie 9.0.9 as suggested and it didn't work out. After all the hassle of loading it and installing it I found the video quality was so incredibly low that it was of no use to me even for basic home movies.


I am in the process of working with my first import with LifeFlix DV Importer and Editor, available in the App Store.

itunes.apple.com/us/app/lifeflix-minidv-importer/id630212114?mt=12


Seems like it will be easy to export to iMovie when I get to that if I want to. I may just leave them in LifeFlix though as I won't want to deal with iMovie. Why not just keep everything in the one that works? If you do want to move them over:

Now this is interesting. Using QuickTime Player (X) to record a new movie directly from the camera seemed like it was going to work. The player showed the audio levels flickering (for lack of a better description) during the import. To make sure it wasn't picking up the audio from the Mac's microphone, I turned the audio monitoring on the camera completely down and could still see the audio levels flickering within the QuickTime window.


Oddly, when I play the new video recording back, there is no audio. So it appears that audio is making its way into the Mac, but getting lost somewhere during transcription to a file.


I tried the same thing using QuickTime Player 7 (Pro) and got the same results. The audio levels were flickering during recording but the file ended up with no audio during playback.

Dec 16, 2017 11:57 AM in response to Joseph Bruni

I dug around inside the ~/Movies directory and found some .dv files that still had audio when played using QuickLook. I copied one of these to the Desktop and then re-imported the clip into iMovie. The audio was preserved and was played successfully in iMovie.


I also monitored Console during another import from the camera and noticed the following:


1) During import there is a rapid continuous stream of warnings coming from iMovie, "Month 13 is out of bounds". (not sure if this is related).

2) Sandbox is blocking iMovie from reading NVRAM. "Sandbox: iMovie(20155) deny nvram-get glk_free_policy_override [Duplicate; no report will be generated.]" Not sure if this is related either.

Video is H.264, Audio is AAC. For grins I used HandBrake to output to MPEG4, but there is still no audio.


I suspect it is a simple software bug that prevents the imported audio from being written to the file. As I mentioned, the audio appears to be coming in since it is affecting the sound levels display inside the QuickTime recording app, but the audio track is empty in the resultant file.

Jan 27, 2018 4:24 PM in response to bnealy

This might be a media related problem. Is it possible that the song that won't play is DRM protected, whereas the song that will play is DRM free? DRM protected songs will download into iMovie but they won't display waveforms and they won't play. iTunes songs from 2009 and earlier were DRM protected. iTunes abandoned DRM protection after that date.

Hmmm. Well, since there is no sound on two different video editor apps and two different computers it might be that your camera is not exporting properly (or unsupported on the new operating systems) or it is media related. As I mentioned before, the original poster's camera does not appear on the supported camera list. You might click on the link I gave and see if your camcorder is supported. I can't explain why one DV tape worked out of the 12 you tried. At this point I am out of ideas. If you find the solution please post back in case it might help others with this problem.


Good luck with this.
