sending me material.

To make the process as simple as possible, please refer to the technical specifications below before you send me the material you want me to work with.

The below specifications are based on my tech-setup’s manufacturer specs (some are directly cited while others are paraphrased)*. If I receive files from you according to these specs, we may save unnecessary technical issues before we can start on your project.

* It may be subjected to minor or major changes as my setup evolves

stand alone audio files (no film, just sound).

Uncompressed PCM (.wav or .aiff), preferably no less than 48 kHz, 24 bit. Interleaved or dual mono depending on what is to be done. Non-dithered audio.

film formats.

Please, always provide a film with a burnt in timecode to secure proper sync. 

A 720p HD resolution is often enough to work with and saves the computer processing power.

IMPORTANT NOTE: If you have a film with dialogue and a temp track, please pan the temp track to one side (e.g. full right) and the rest to the other side (e.g. full left). This will allow me to separate the temp track from the other audio while working, but still be able to A/B-ing it for quick reference.

Recommended encoding settings for H.264:

You should take care of the following settings when creating H.264 video files:

  • The number of B-frames should not be higher than 3. Anything above will lead to an unreasonably high amount of memory allocation.
  • The number of reference frames should not be higher than 2.
  • To keep the playback performance up, it is very important to disable weighted P-Frames, weighted B-Frames and pyramidal B-Frames.
  • Furthermore, make sure to use a key frame interval (IDR) of 1 frame (thus every frame is encoded separately).

embedded audio formats for film audio extraction.

  • Codecs: PCM, AAC* (MP3, MP2 and AC3 are not supported)
  • Audio sample rates: 8 kHz, 11.025 kHz, 12 kHz, 16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, 48 kHz, 96 kHz
  • Audio bit depth: 8, 16, 24, 32 bit float
  • Audio channels: mono, stereo, multi-channel files with up to 48 channels. 

*Additional notes for AAC:

  • AAC decoder automatically uses the channel configuration of the input stream (mono, stereo, multi-channel).
  • General limitation: only 1024-sample frames are supported.
  • AAC-LC with a 960-sample frame size is not supported.
  • Coupling Channel Elements (CCEs) are not supported.
  • Sample rates higher than 48 kHz are not supported.

project files.

I accept AAF files with:

  • copied media.
  • muted events set to a volume -inf dB.
  • I prefer all to one file before export file references as relocating the files may be unnecessarily time consuming.

OMF is possible but not suggested as it adds more work.

Please test the project file before sending it to me to make sure that all you want to be there is in fact there. If you send individual tracks with plugins, remember to bounce them since I may not have the same plugins or versions of them. AAF files do not include plugins, Midi, or VST s, so, if these are relevant, remember to render in place before exporting to AAF. Audio channels will be delivered in dual mono within this format.
