However, HyperDeck Studio has a unique feature that helps with ISO recording. It will allow
youto completely reverse this process and resynchronize the video input to the reference
input. What this means is you can connect a non-sync source to the HyperDeck and it will
retime the video input to the video reference and then record it.
Non-sync sources could be computers, consumer cameras or any video equipment that is
unable to have a reference connected to it. It could even be an incoming video feed from
another studio or external broadcaster. Non-sync sources cause problems with ISO recording,
as you need the timecode on all recordings to match perfectly over time. A non-sync source
willrun faster or slower than your other sources and slip out of sync vs the timecode quite
quickly during the recording. This makes multi-cam editing a horrific process as the sources
won’t have matching timecode.
With input re-sync turned on, the HyperDeck video input will be analyzed and if it starts
fallingbehind a frame will be repeated, or if it starts running ahead of the reference, a frame
willbe removed. This is called resynchronization and the processing on the input is called a
frame re-sync. It means the timecode in the clips being recorded on all decks will have the
same events happening at the same timecode. It makes multi-cam editing possible.
Of course the downside is you are adding some frames to the input, or removing some
framesfrom the input before recording. This is why it’s best to leave this feature turned off
andto only use it when you absolutely cannot do anything to connect a reference to an ISO
source because it’s a computer or consumer device.
However, there is one situation where you can turn the input re-sync feature on and use it.
When input re-sync is turned on, the HyperDeck video output will remain reference locked
even when the deck is recording. What this means is you can connect the SDI output of the
HyperDeck to a camera to lock the camera to the reference via the program return feed.
Agood example is the Blackmagic Studio Camera 4K Pro and it can set its reference to the
external video. Then the camera feed will be reference locked from the HyperDeck and the
HyperDeck input re-sync won’t have to add or remove frames because the camera is not
running fast or slow.
The input re-sync only does something if the video input is not locked to the same reference
asthe HyperDeck. But in this case, the HyperDeck output is the reference source to the
camera and the HyperDeck is locked to its video reference input. If you have multiple
HyperDecks all locked together by looping the reference connections, then all cameras and
HyperDecks will be locked as a single group. Then if one of the HyperDecks in a group has
anon-sync source, such as a computer, then that one input will be resynchronized, but the
other sources won’t need anything.
The re-sync is automatic so you can just connect sources and it will work. The input re-sync
feature can be extremely powerful, however, it’s important to know when it’s going to do
something and what it will do. Try some experiments with multiple HyperDecks and multi-cam
editing software to see how it works! It’s a fantastic way to do program production that’s
very fast.
