Hi to all
I have been experienced some problems with audio sync after produced in PowerDirector12 (12.0.2726.0)
I browse the forum looking for sync issues, and I found some, but no one fit my scenario
I have original MP4 1920x1080 59.94fps with time duration about 50, 60 or 90 minutes, and after produce the video I get between 200 and 400 milliseconds out of sync, is no much but is noticeable when people on video "talks" and the lips are out sync with audio
I notice this un-sync audio with produced video with or without cutting any part

My produce steps are
1) Original file is
Video
H264 MPEG-4 AVC 1920x1080
FPS: 59.94
Bitrate 10.11Mg (or about 10352kbs)

Audio
AAC
Sampling rate: 48khz
Bitrate: 128 kbs

2) I do some improvements with “fix/enhance” (denoise, enhancement and color)
3) Then I cut unwanted parts (if apply)
4) Select all parts and “group the objects” in order to be one
5) Produce with a custom MP4 profile
Video
H264 MPEG-4 AVC 1280x720
23.976fps
Bitrate 6000kbs
Entropy CABAC

Audio
AAC Stereo
Sampling rate: 48khz
Bitrate 128 kbs

My computer is a laptop Asus G750-JX with I7 and Gforce-GTX770M
Win8.1 (up to date)
I upgrade my PD12 software to last patch (12.0.2726.0)

What I notice is that PowerDirector use 100% off CPU when is producing (all 8 cores), I am happy for PD to use all the power, but it can be symptom of a problem…

How should I aust the audio to video in miliseconds??
I try to unlink the video/audio, but no option to displace the audio 200 milliseconds.
It should be a procedure to fix it but no sure how…

Thanks to all for read

Why do you need ca 24 fps? Best results are for same as original.

What else do you have running when the program is encoding the video - anti-virus? Internet? e-mails? etc.

How many programs start at boot? Try reducing those by using Windows mcsonfig.exe -- start up. Stop those that you know you don;t need to start. .

Thanks Stevek, I have antivirus (Emsisof) but I don't think is a performance problem (because much procesing), in normal use the CPU is a 4% used capacity, and when I'm producing I only do that.
I drop the FPS to 24 for reduce file sisze Daniel Saxer

Did you look at all the programs that start during boot? Again, go to start/run, type in nsconfig.exe and look at everything with a checkmark in the start up page - you will be surprised.

You realize that the video gets softer at the lower frame rate? Don't complain about quality if that happens. It may also be the cause for the audio sync issue. If you are burning to DVD then the standard rule of thumb is one hour of video onto a standard single layer DVD regardless of other settings. If you are worrying about file size for other than DVD, then you may want to invest in some inexpensive thumb drives or external hard drives.

Of course, if you have a camcorder that has the option, you may want to set to to record at 24 fps.

Important ! I just noticed that the latest update to PowerDirector 12 does address some problems with sync when changing frame rate. Do you have the latest update installed? Build 2726. .

yea, I edit audio, take the first second and change the duration to 1.4 seconds and this solve the audio sync problem, but it must be a bug because always is 400 millisencons...
