DR stopped supporting ac3 audio in .mts files?

Hello everyone,

Couple of weeks ago I was using Davinci Resolve 18 and editting the .mts files that comes from my Panasonic HMC 150 camcorder.

I was using windows 11 and everything was working fine.

This week I formated the pc and re installed Davinci resolve (version 19) and whem I throw the clips on the timeline DR doesnt recognize the audio files anymore. there is no waveforms.

I noticed that windows 11 (22h2) stopped supporting ac3 audio files, there is no sound when you play the files on windows player. But when I installed VLC the sound was back to normal.

Since that I cannot edit the files on DR with audio on it. I tried to down grade the program to several versions prior to 19 but with no sucess.

Thats so frustating. Even with windows not supporting ac3 anymore davinci should be able to recognize them. Now Im using handbrake to convert the files to aac or mp3 and its a pain cause I have to re sync with the video files on the timeline.

Does anyone else is facing the same issues?

Resolve will often draw on the OS and hardware for codec support.

If that support goes missing from the OS or hardware...

sure!


here it says that there is no support for AC3 codec.


here is Davinci with no waveforms

Today I downloaded Dolby AC-3/AC-4 Installer. Now Windows media player is playing the clips with sound but Davinci keeps without waveforms and no sound at all.

According to this list it is supported:

What happens if you re-wrap into .mov?

Today I found the solution!

Went to techspot.com and downloaded Microsoft Dolby AC3 Installer.


Everything is working back to normal again. thank you guys!

Hello,
Thank you for this solution to the problem of playing sound on .mts from my Panasonic VX870 camcorder. I just installed a new desktop under W11 pro v 24h2 and it had become impossible compared to my old PC under W10.
Everything is back to normal
Greetings
