Below are the delivery specs to abide by for file delivery. Before you begin your export, it’s a great idea to check out this blog post over at Frame.io. How to Keep Your Sound Editor Happy



PICTURE:

• Quicktime Movie file with visual burnt-in timecode in the lower-thirds.
  

• Video frame rate must match frame rate of the exported OMF / AAF sequence(s).
  
  The following are my preferred file specifications:
  
  File Types:
  

• Apple Pro Res (Preferred)
  

• Avid DNxHD
  

• If using H.264 .mp4 format please note that this is not frame accurate and the codec compression can knock audio off sync by anywhere between 1/4 and 1/2 frame. If using .mp4 it is vital that use use a 2-pop AND tail-pop (see video below) .
  
  Resolution:
  

• HD 1920x1080 (Preferred)
  

• HD 1280x720 (Minimum)
  SD 720x480
  
  Audio:
  

• Left / Right Stereo file for reference embedded in video
  

AUDIO:

• Audio File Type: broadcast wave (.wav)
  

• Bit Depth: 24 bits
  

• Sample Rate: 48kHz
  

• Handles: Minimum of 5 Seconds (120 frames @ 23.976, 150 frames @ 29.97, etc)
  

• Audio must be delivered as an embedded AAF or OMF file, which contains all audio within a single file.. I prefer AAF as OMF does not retain the metadata from production sound.
  

• Include a 2-pop at exactly 00:59:58:00
  

• Picture must begin at 01:00:00:00 so when a 2-pop is included the first frame of the file should be 00:59:58:00. This assumes you’ve trimmed your academy leader down to just the “2”.
  

• Timecode format of AAF/OMF must match that of the corresponding video
  

EXTRAS:

• pdf of lined script (if available) or finalized script
  

Please note: Embedded OMF 2.0 file types have a file size limit of 2GB. If your project is larger than this, please split the project by reels of no longer than 20 min and note the exact timecode of the start and stop for each reel. 

Understanding the Significance of Audio Metadata

Metadata plays a crucial role in audio files by encapsulating valuable information such as frame rate, scene details, shot particulars, character names, microphone specifications, and notes regarding audio nuances. Additionally, it includes essential data about the audio recording process and contact information for the responsible party.

Why is Metadata Important?

The presence of metadata significantly streamlines the process of editing and refining dialogue, making it more efficient and cost-effective. Here's why:

• Simplified Organization: Metadata enables efficient organization, allowing for quick sorting, muting, or trimming of unnecessary clips without the need for extensive listening. Properly labeled clips facilitate seamless navigation and management during post-production.

• Enhanced Searchability: With identifiable track names, locating specific audio segments by scene, shot, or take becomes effortless. This feature proves invaluable when substituting alternative takes, saving time and resources that would otherwise be spent on exhaustive searches.

• Time and Cost Efficiency: The absence of metadata results in prolonged search times and inefficient workflow, ultimately impacting project timelines and expenses. By contrast, comprehensive metadata ensures smooth operations and optimal utilization of resources.

In essence, metadata serves as a cornerstone for effective audio management, offering invaluable benefits throughout the post-production process.
