Rendered Video(many blinks in first 30s):

Same thing happens in the editor. Videos were backed up from iphone to google photos > downloaded onto PC for editing and rendering. The blinks don't always appear in the same spots, one render will have many in the first minute but another render of the same video will have little to none in the first minute.

Vegas Pro 17

Not "quite" BB VB.

Your source is Variable Bit Rate. With Vegas Pro 17 you are likely to have problems.

Encode in Shutter Encoder or Handbrake first.

You can see if setting dynamic ram preview to 0 helps but my suggestion is also to give VP 17 constant framerate AVC that it can easily deal with. Newer versions of VEGAS perform somewhat better with such media though feeding it easy to decode media is a best practice (I use ShutterEncoder myself).
