LTC audio support within the Telemetry Overlay software

Linear (or Longitudinal) Timecode (LTC) is an encoding of SMPTE timecode data in an audio signal. Telemetry Overlay can parse date and time data from videos that have a compatible (both date and time) LTC audio channel. You can record such a channel by plugging an iPhone/iPad with the Protern Clock app to your camera via an audio cable or by using a DISH device. Make sure to enable the "LTC from audio" setting before you import your footage by choosing the time format your device records: Dish records Atomic time, Protern Clock is Atomic by default but can be changed to UTC, and for other generators you need to check their documentation.

This can be very useful to assist with automated and manual synchronization of video and data. Any data source that contains valid UTC timestamps should sync automatically to a video with a compatible LTC audio channel.

Supported gauges in Telemetry Overlay

Time & Date, Custom, Dynamic Text, Static Title, Static Image and Watermark.

Availability may vary between devices and recording conditions.

Other LTC audio timecode recorders like Tentacle Sync or LTC Timecode Generator for Android might also work, as long as they follow the required format. The User Bits must contain the current date as either yyyymmdd or ddmmyy00. Devices that record the Local time will only work correctly if you edit your videos in the time zone where you recorded them.

When you optimize your footage or export it, the program will try to mute the unpleasant LTC audio track automatically. If you skip the initial optimization process, you might want to mute the video manually.

Telemetry Overlay supports most video formats and dozens of embedded and external data formats.

Gauges can be customized to a great extent, but presets and defaults can make the user experience extremely easy.

Map and satellite imagery is available for representing GPS data.

Export formats for both professional and social use are available.

Lots of documentation, tutorials and an active community help achieve great results.
