I imported some video files imported from my camera and when I play them the image plays correctly every-time no matter what software i use but there is no audio when i play it using quicktime or iMovie, there is sound however when I play it using VLC or on google drive (same file).
MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.2)
Hi, Gaelen,
Your Pentax Optio WG ll is not listed on Apple's website as an iMovie supported camera. That's probably because of the audio codec used in the video, which I believe is not supported by iMovie. iMovie likes Mp4/AAC (advanced audio coding). However, the .mov video portion of your video clip works fine, so you need to convert the audio part to a codec that iMovie supports.
Open your video clip in VLC and use that app to convert the audio to Mpeg 4 Audio (AAC) and you should be good to go.

Hi Rich,
Sorry I forgot to include that initially, my bad.
video codec: H264
Video format: .MOV
Audio format: not exactly sure how to find it sorry.
Audio codec: PCM S16 LE (sowt)
Camera model: Pentax optio WG-II
Imovie version: 10.1.8
That's all I could find, if there's anything I'm missing let me know, Thanks!

For some reason there is still no audio when I play it in imovie or with quick time even when the audio codec is converted to mp3. would the fact that it is saved as a m4v file have anything to do with this?
Hi,
We need more details. What format is the video? What format is the audio? What model of camera? What version of iMovie?

Hi Rich,
When I try and do that i get an error message saying "Streaming/Transcoding failed: VLC could not open the mp4a audio encoder"
What does this mean?
Gaelen
Hi Rich,
I decided to try some of the other audio formats and the "mp3" audio codec seems to work without a problem for some reason, any idea why mp4a wouldn't but mp3 would?
Gaelen
I have no idea why that happened. However, Mp3 is supported by iMovie. Do you now have sound on your video when played in iMovie?
-- Rich
It shouldn't. M4v and Mp4 are virtually the same thing.
audio not working properly on imported files
