## hyperdecks

`nc ip.ip.ip.ip 9993`
`remote: enable: true ↵`
`record`
`stop`
`play`
`clips get`

playrange set: in: 00:00:16:00 out: 00:00:21:00
play: speed:50

note: set `timecode output: clip`

### sample workflow

- record (while NOT routing the feed from the hyperdeck to the TV)
- stop, play . . . switch so TV gets audio from hyperdeck (but nowhere else)

### instant replay concept

- two hypers
- hyper.a
- hyper.b
- initially
- hyper.a receives PGM1
- hyper.b dormant
- request for replay hits
- hyper.b starts
- hyper.a stops
- hyper.a queues to timecode requested
- atem switches to hyper.a playback audio ONLY
- pan to one side?
- atem sends audio at this point (mix minus?)
- hyper.a play (with speed requested)
- atem switches to display hyper.a on PGM1
- somehow audio hits speakers and condensers are cut

## to do

### macros

looking like this may be the only way to access cameras . . . also a good way to access everything else.

#### determine macro upload/download structure
do the first and then the second:

public async downloadMacro(index: number): Promise<Buffer> {
    return this.dataTransferManager.downloadMacro(index)
}
public async uploadMacro(index: number, name: string, data: Buffer): Promise<void> {
    return this.dataTransferManager.uploadMacro(index, data, name)
}

#### can you restore with code?

is there a method for restoring the ATEM based on an XML?
