Hi - I am trying to burn a movie created with a Panasonic HC-V750 camcorder to BluRay disk using PD12. I have imported my files and edited the movie. Then using Create to burn to BluRay disk and playing in my BluRay player on a 52in Samsung LCD TV.

The picture quality on the final BluRay disk looks very good, but the audio quality on the BluRay disk is significantly worse than the original files. In particular, it becomes difficult to hear voices (ordinary conversation). The base appears to be amplified, somewhat drowning out someone's voice. Yet playing the original files on my PC, the speech is much clearer.

Do you know why this occurs and what I can do to fix?

thanks in advance for help! Physically fit = Mentally fit

Not sure if your original HC-750 recording was 2 channel or 5.1, the camera supports both. You can check audio of original clips in the media library with a right mouse click "View Properties". On the create disc tab, what audio format did you select? What you describe almost sounds like stereo to DD5.1 conversion. I'd try one of the 2 channel audio settings and see if you are happier with BD sound, LPCM would be my selection for first test.

The camcorder recorded 5.1 channel sound. When burning to Bluray, I tried both 2 channel and 5.1. Made little difference. 5.1 was maybe slightly worse, but 2 channel was still markedly worse than playing the original files on my PC.

vijay0828 - What is the model number of your camera with the problem?

Hi - the camcorder is a Panasonic HC-V750. But the camcorder is not the problem. The footage transfers fine to my PC and the audio quality is very good when I play the video clips through my PC.

The problem occurs after producing a movie in Powerdirector 12 and burning it to BluRay. The resulting BLuRay has very good video quality, but the audio is significantly degraded. Background noise is amplified and people speaking becomes difficult to hear.

Is user vijay0828 the same as user lasereyes66?

Any chance you can attach a small clip from the HC-V750 that when burned to BD has the audio issue to aid a possible solution. Also for reference, what is your PD12 pref audio format set to?

The panasonic website will only allow viewing the basic operating instruction and not the advanced manual supplied to the purchaser of this particular camcorder. You need to read that manual and set the mic setup from manual adjust to auto, bass setting to 0, in the record menu for future recordings.

For the clips you have now in the timeline of PD12 go to the audio mixing room and adjust the left right slider for that track with the panasonic clips and adjust the slider left from 50 to 10. Create a short section BD-RE and the problem of the amplified base should be improved greatly.

Let us know if this solves the problem on these clips.
