Solution: Go by your Markers and wave form alignments and not preview to sync audio.
You guys aren’t going to believe this. Dan nailed it. I am using the preview to sync my audio to video even though I have markers in the audio file and which collates with the cameras audio. The part you aren’t going to believe is that it takes exactly 6 frames advancement of my audio to line up the markers and waveform. There must be some similarity somewhere in the first post I pointed to though. I wasn’t looking at the wave-forms as I thought preview sync would collate into the real thing. How that is consistent between each project squarely lands on the hardware as Dan has stated. So I determined this by aligning the markers and wave forms on each project. This puts the preview audio out sync. Then I measured the space I moved on each project and there it was 6 frames on every one, but, again the wave forms align up. So it’s a preview problem, but now it’s been explained and I will continue on. I will test this on my new projects coming up and keep you posted. Thanks Dan. Thanks Austin for the tips below.
Again if there is a setting in Shotcut that I need to use that you may recommend, that may in the future possibly allow the preview audio to sync up as I align to the waveform, then just point me in the right direction. I believe as Dan has stated and it is system dependent. The same thing was happening in kdenlive and is why i jumped ship. I like Shotcut better but now it all makes sense.
