Sync with timecode on set
The purpose with using time-code is to assure that all video, sound and script-notes are synced in order to simplify post production.
The challenge with this activity is that there seldom is a clear accountability or responsibility for this activity, as cinematographer, sound engineer and script supervisor are involved together.
Our suggestion is that the sound engineer is responsible to provide all additional equipment needed for time-sync, but that 1st assistant director is accountable for the activity. e.g. take decision to shot with or without timecode.
Lack of time code or failures with time code will lead to increased time during edit in post-production.
We also use a slate and microphones on each camera as backup if time code fails.
We use a sound recorder, either a Sound Device or Zoom F8 as master for time-code. Simpler recording devices as Zoom H6 don't have support for time-code or metadata, som they are therefore not an option for scripted productions.
IMPORTANT. When powering down the recorder, you should re-sync each jam-synced device. Have a habit of doing this after each longer break and change of location.
The cameras we normally use, (e.g.) video cams, DSLR, mirrorless and action cams don't have an input or output for for time-code. Neither do the have any possibilities to add metadata to there clips.
The solution is therefore to use an external time-code generator, and we use Tentacle Sync as they are reasonably priced and simple to use. Each Tentacle Sync device is jam-synch via cable to the sound recorder.
Use an appropriate cable to connect to the cameras audio input and set correct level for timecode audio signal.
We use MovieSlate as an electronic slate and to take script notes. The slate is jam-synced with the sound recorder
This gives us the ability to later automatically add scene, shot, slate and take to the individual video clips.
If the electronic slate fails, we have a manual slate as backup. However, this will lead time additional work in post production.
