It obviously varies depending on the scope of the videos you’re looking to produce, but I think you should start conversations about charity fundraising appeal videos at least six months in advance of the campaign launch date.
There might be one-off events happening in the run up to the appeal which you want to capture, or there might be people you want to interview for the video who have limited availability.
Additionally, there may be some parts of the videos, such as case study interviews with vulnerable service users, which require a longer approval process.
Giving yourself at least six months to produce your campaign video means you’ve got plenty of time to overcome any obstacles.
