Rendering issues & Audio sync problems

[jcsupercell]

So I'm rendering a youtube video and I keep getting issues with audio syncing, the video lags behind the audio whenever it renders in sony vegas and its not like this whenever I record it off my webcam, but when I try to edit it ends up with audio and video sync issues and it's getting EXTREMELY FRUSTRATING.

What rendering software are you using? What Operating System? Any thing else running in the background: AV checks, backups, updates, etc.?

Does your system meet the minimal hardware requirements for the rendering software?

And "minimal" tends to be a measurement at which the software will work but the functionality is likely to be impaired.

Check the software specs.

Task Manager, Resource Monitor, and Performance Monitor will help identify any existing bottlenecks.

Could be a matter of CPU power, memory, disk speed, etc.. Graphics card - may be pressing the PSUs capabilities. Especially if an older PSU.

I'm using sony vegas pro 13, with nothing else running and here are my pc specs:

Does your graphics card meet the specs? What disk drive are you using?

What do you see in Task Manager, Resource Monitor, and Performance Monitor?

Any component on your system showing a high % of use while rendering is likely to be the bottleneck.... Memory and CPU appear ok with respect to the required specs. But you must go into the details. E.g., 8 GB of slow RAM may not match 4 GB of fast RAM.

Details matter.

Try to disable GPU rendering (Options - Preferences- Video - GPU Acceleration of video processing).
