Question: The Oscar winner is urging film lovers to help the campaign to raise the final instalment for the £450,000 project.
The National Library of Scotland's moving image archive will move to Glasgow's Kelvin Hall in the autumn.
Film producer Iain Smith, actors Brian Cox, Alan Cumming and Bill Paterson are also backing the campaign.
Mr Scorsese, who set up the World Cinema Foundation, said: "Moving image archives hold our common memory.
"For that reason, we need to care for them, and treasure them. That is our obligation. We owe it to future generations.
"Films shouldn't be locked away and neglected in a vault somewhere. They need to be protected and preserved, but they also need to be seen, studied, and enjoyed.
"I enthusiastically support the efforts to develop the Scottish Moving Image Archive, and I urge you all to support this vitally important initiative."
Scotland's moving image archive is the national collection of amateur and professional films which reflect Scottish life, society, industry and culture from the 1890s to the present day. It holds over 46,000 items in total.
In the autumn it will move from its current home on an industrial estate at Hillington outside Glasgow to a purpose-built facility at the Kelvin Hall.
The central location in Scotland's largest city will make it easier for the public to visit and take advantage of the new facilities for exploring the archive.
The fundraising campaign will help to create improved viewing and learning areas including videowalls to showcase films, a public drop-in area, a curated content area, research space, viewing booths and manuscript consultation space.
There will also be a small cinema to "provide a high quality screening experience".
Visitors to the Kelvin Hall will also be able to access digital content from across the library's 24 million items and explore a permanent exhibition space.
Dr John Scally, National Library of Scotland librarian said: "The move to the Kelvin Hall will provide the perfect showcase for our moving image archive and for our wider digital collections.
"It is important to have such high profile endorsements for the developments we are planning. We will be working hard to raise the funds needed to make this into a memorable destination for visitors."

Sum: Movie director Martin Scorsese has called for help to raise £250,000 for state-of-the-art technology to view and study Scotland's national film archive.


Instead the Volkswagen Golf topped sales, according to the country's carmakers' association, although Volvo still had the largest share of the country's car market overall.
The Golf made up 5.9% of new cars bought in the country, while Volvo's V70, S90 and V90 took 5.7% together.
Volvo was last knocked off top spot in 1962 by a Volkswagen Beetle.
Despite Volvo's car business now being owned by a Chinese firm, Zhejiang Geely Holding Group, it is still viewed as an iconic Swedish brand.
And it still sells the most cars in Sweden, with more than one in five cars (21.5%) on the country's roads, compared with Volkswagen's 15.7%.
However, Volvo's V70, the most popular car in Sweden for the past two decades, has ceased production in favour of the newer V90 model.
Sweden is Volvo's second-biggest market behind China.
The Swedish carmakers' association said 2016 saw record car sales with 372,000 new registrations, up by 8% on the 2015 figure, helped by a strong economy, while truck sales were up by more than 15%.

Sum: Sweden's best-selling car in 2016 was not a Volvo - the first year that has happened in more than half a century.


"I think we should've done better to try and get the game on," he said.
Mark Jones, head of operations at Rodney Parade, was "disappointed" by Sheridan's comments.
"The pitch was in a playable condition... It then started raining heavily at 12:45," said Jones.
Newport had been confident earlier in the week that the match would go ahead but referee Charles Breakspear called it off after heavy rain on Saturday.
League Two side County and Newport RFC had games postponed last weekend due to a waterlogged pitch at the same ground.
The FA Cup fixture could be rearranged for the week starting Monday, 18 January.
"I feel as though we should've prepared a little bit more for the weather," Sheridan told BBC Radio Wales.
"We knew it was a massive game for us and it was important we got the game on.
"It's not me who's going to be chatting with him [Jones] but I feel as though we should've done our best to get the game on, and I don't think we did."

Sum: Newport County manager John Sheridan criticised the club's ground staff after their FA Cup third-round tie against Blackburn was postponed due to a waterlogged pitch at Rodney Parade.


The Cardiff City and Wales player told the Sunday Mirror: "All I know is that my best mate has gone. I'm struggling."
Ex-Premier League star Speed was found hanged at his Cheshire home last year.
His parents and family members marked what would have been his 43rd birthday on Saturday with a walk up Moel Famau, Denbighshire, near his childhood home.
Roger and Carol Speed told Wales on Sunday the family are still coming to terms with his death in November 2011.
Bellamy, 33, whose former clubs include Liverpool and Manchester City, told the Sunday Mirror he has moved out of the marital home he shared with his wife Claire and their three children.
He said: "Losing my best mate has affected everything. I can't believe how hard it is.
"He was the best mate I've ever had. It's sad but unfortunately it got to my marriage. I'm here and she's there.
"I don't know if that's it for us. All I know is that my best mate has gone. I'm struggling. I can't lie."
Bellamy told the newspaper of his family situation: "I can't tell you how hard it is. It's the worst time in my life ever."
Bellamy was part of the Team GB squad at the Olympics, and last month joined Cardiff on a two-year deal from Liverpool.
Speed's clubs included Leeds, Newcastle, Everton, and Bolton, and he managed Sheffield United.
A coroner at the inquest in January said he could not be satisfied that Speed intended to kill himself.

Sum:
Answer: Footballer Craig Bellamy says the death of the former Wales manager Gary Speed has led to the "worst time in my life" and the break-up of his marriage.
