Most festivals require you to submit a snyopsis or tagline along with your film here’s a helpful article on how to write one from our friends at Sundance.
Submitting your film online? You want to ensure you are sending the best file quality possible while not eating up all of your bandwidth uploading a huge file. Start by exporting your film from your editing programme to the highest quality possible.
There are a few free programmes you can use to compress your file with little quality loss.
Choosing a still to represent your film is also important as this will be the one visual representation for your film in brochures and online.
Make sure to choose an image that you feel captures something important from your film, a character, an emotion.
Make sure the image is high contrast and clear so it will print well in black and white as well as colour.
