# Wiretap Limitations

It is important to note the following limitations:

- Fade-Ins: Avoid having a timeline starting with a fade-in at record timecode 00:00:00:00.
- Tape Names: Avoid using different shots that have the same timecode and tape name.
- Hard-Committing: Hard-committing a selection of shots creates a new clip with a tape name of COMMIT, and a source timecode obtained from the record timecode. There is no need to add this information to the shot manually. Hard-committing a single shot preserves the original tape name and timecode.
- Start Timecode: The Start timecode of the timeline should not be negative. Also, avoid using a timeline that begins with a fade-in and has a start timecode of 00:00:00:00.
- Saving to a Clip Library: Once you have added a clip to a clip library, make sure to switch to a different clip library. This both saves the clip library, and allows Wiretap to broadcast the updated information about the timeline and clips.
- Dual Library View: In Visual Effects and Finishing applications, the Dual Library View mode displays the contents of two clip libraries simultaneously, each in its own panel. When you switch from Dual Library View back to Single View, the newly-hidden library remains selected by the application, and is read-only to Wiretap. Lustre will be unable to render media to the clip library until it is deselected.
