Crawford Allan says the SFA are hopeful of introducing VAR to Scottish football by the end of 2022.
The Head of Referee Operations reckons the technology could be in place during the 2022/23 season, its implementation coming after next year's winter World Cup in Qatar.
The 42 SPFL clubs will vote on its introduction to Scotland's top flight at a general meeting in February.
Should it be agreed that VAR be introduced, it will take around 12 months to get the system in place.
Motherwell manager Graham Alexander has been a big advocate for the tech which aims to help referees make key decisions via a video assistant.
Allan told Sportsound: "Our desire is to bring it in as early as we can. There's not one referee that I've spoken to that doesn't want it. We're doing what we can in the background to try to speed it along. It's going to take a while.
"VAR's there to fix clear and obvious errors.
"You're not trying to prove a decision was correct, you're trying to say, 'was the decision clearly wrong?'
"VAR will be there to help with the big decisions, the factual ones and the ones that are clearly wrong."
