Import Media

hese preferences define how Tin Man handles media import defaults when certain metadata is missing or when optimization settings are needed for playback performance.

---

Timebase and Timecode Defaults

• Indeterminate Timebase Sets the default frame rate to apply when a video, audio, or image sequence does not contain valid timebase metadata.

• Indeterminate Timecode Sets the default starting timecode for media that lacks embedded timecode information.

• Indeterminate AAC Sample Offset Defines the default sample offset for AAC audio, which often has an inherent delay of 2112 samples.

  This value typically shouldn't be changed unless you're compensating for known sync issues.

Audio Mapping

• Discrete Audio Mapping When an audio channel is labeled as "discrete," this setting determines the default speaker output mapping for that channel (e.g., mapped to Front Left, Right, Center, etc.).

Playback & Performance Settings

• Playback at High Depth If a file supports multiple bit depths for playback, this sets whether high bit depth decoding should be the default.

• Enable Direct I/O When enabled, Tin Man uses Direct I/O for faster disk access, improving performance for large files or high-resolution footage.

• Use More Memory Allows the video decode engine to allocate more memory for improved decoding performance on capable systems.

• Hardware Decoding Toggles the use of GPU-accelerated decoding for supported video formats.

  Can improve playback speed and lower CPU usage on supported hardware.
