My son applied to film programs. Some didn’t even want a portfolio. Some did. It really depends on the school. Talk to admissions is the best advice. Some film schools had specific information sessions on what they wanted in a portfolio.
I would look at acceptance rates for the programs as the best gauge. Then GPA/scores. Don’t use the overall acceptance rate at the school. It could be much different than the area you apply.
It’s a nerve racking process without a portfolio. Even more unknowns with a portfolio. My best advice is to just do your best, apply and move on. You can drive yourself nuts over analyzing your portfolio.
Might help to mention the schools.
