"Registration" is how filmmakers, fans, and individuals in the entertainment industry purchase a badge to attend and participate in SXSW, including the Film & TV Festival.
A Film & TV Festival "submission" is how to have your work considered for the SXSW Film & TV Festival Program. You do not need to purchase a registration credential to submit a project. If you’d like to submit your project for SXSW Film & TV Festival consideration, please start your application process here.
