Technical Requirements For Screening

ASFF is a digital festival and prides itself on the technical quality of the films shown. All films screened at ASFF are edited onto genre reels where films play back to back without the need to break. We believe in not only showcasing the best short films from around the world, but also in creating a seamless and engaging audience experience.

Technical Formatting Guide

ASFF is a digital festival and we only accept Quicktime files created using the below specifications. We will not accept playable DVDs, tapes, or film reels.

Films should be submitted as high quality Quicktime in the following format:

  • Quicktime wrapper – Apple ProRes 422 codec.
  • Audio Codec – Integer 16bit 48KHz Stereo
  • Resolution: 1920 x 1080 Progressive
  • Frame rate: 24fps or 25fps

If bandwidth is an issue we will accept:

  • Quicktime wrapper – H.264 codec (minimum data rate of 10Mbit/s)
  • Audio Codec – Integer 16bit 48KHz Stereo
  • Resolution: 1920 x 1080 Progressive
  • Frame rate: 24fps or 25fps


Codec: ASFF uses Quicktime ProRes422 as its working codec. Please do not submit films at higher bitrates (422HQ, 4444) as it adds a undesirable overhead to our workflow. The filmmaker gains no quality advantage by submitting higher bitrates because ASFF will transcode back to ProRes422.

Aspect Ratio: Cinema ratios of 2.35:1 or 1.85:1 should be centred vertically between black bars in a 1920×1080 16:9 frame, filling the width of the frame.

Technical Compliance: It is the filmmakers responsibility to ensure that the delivered film is technically correct. The festival can only spot-check the film before exhibition. Please check your film thoroughly before delivery.

Audio Mix: All ASFF films will be exhibited in stereo. Please do not supply a 5.1 mix.

Padding: All colour bars, leaders, cigarette burns and audio cues should be removed, include 3 seconds of black video padding at the beginning and end of the film.

Subtitles: Any subtitles must be clearly legible (refer to the guide below).

File Name: Please ensure your Quicktime file is named as the title of your film.

Subtitles and Captions Guide

Any subtitles and caption must be clearly legible. Please pay particular attention to font size, type and subtitle colour. White text on a light background will be hard to read. Where necessary ensure subtitles have a border/drop shadow or are presented in a different colour to white to ensure the text is clearly legible.
