Im using Sony Vegas Pro 14 for a while now and nothing like this has happened before.
I started editing using the preview option Draft(Quarter). I finished editing, but then when I tried to render in 1080p, 720p etc, the edit is not coming aligned. Then i cancelled the render and i tried switching preview mode to Good(Quarter) and the edit is again misaligned. I will attach some screenshots and if more data is needed, i can provide it but please resolve this i have never got anything like this. This video is to be uploaded to youtube. I have also matched the project properties with the media file.
In draft(quarter) preview: https://prnt.sc/hq3mb0

Thanks!
