Sony KDL Audio Sync 2.6.7

[mezzmo@mvg.za.net]

Hi All

I seem to be having audio sync issues with my Sony KDL-32EX600 TV with Mezzmo 2.6.7.

The audio starts off fine and then the lip sync slips throughout. Stopping and restarting helps, but then the lip sync slips again.

FFMPEG Properties as follows:

The file has been pre-transcoded and the video appears perfect.

Any suggestions?

Hi Mark,

Contact us at support [at] conceiva [dot] com and we'll supply you with a beta version of Mezzmo v2.7 to try.

Hi

As I mentioned in my e-mail reply:

I tried the beta, with no luck, the audio lip sync still starts off OK and then gets worse as the movie progresses. Stopping and starting seems to re-synchronise the audio and video for a while.

Also, after the upgrade to the Beta, the file which had been pre-transcoded was transcoded again. See image attached.

Hi Mark,

Thanks for letting us know about the duplicate pre-transcoded files issue. We replicated it and fixed it. It will be included in the upcoming Mezzmo v2.7 release.

We also replicated the audio sync issue and we think we have fixed it. We're just testing it on several videos now. We'll be in touch when we're done.

Cool, can't wait. :-)

Hi Guys

Any news on this? I know you said you thought it was fixed, then you found another issue... Is it fixed now?

Thanks
Mark
