Is there any Blackmagic pruduct for time shift?

PostFri May 19, 2017 6:16 pm

I would like a fullHD product for time shift.
Like continusly recording and in the same time playback 10sec "time" shifted the same material.
I have a BMPC 4k and a BMMSC 4k so it's HD-SDI environment.
I'm planning to buy an ATEM Television Studio Pro HD for mixing.
Is it possibile whit any of Blackmagic recorder the time shift playback like I need?
Thanks

Not directly. I have used the H.264 Pro Recorder with some Windows software to do this.

This lets me feed the delayed source back into the ATEM while having a recorded file at the same time (using .TS file and REFs file system for reliability).
If you just want to delay the program out for live streaming then OBS (with a Decklink card) can do this using a memory buffer for playback while recording at the same time.

Anything else, especially UHD, seems very expensive (although professional).

I used a BM mini-recorder and mini-monitor with their products to do something similar on one MacBook Pro - it will record to a growing file and play it back. They have trial versions. You need 'movie recorder' and 'on the air video' apps.

I'm pretty sure you need 2 BM devices to be able to record and play at the same time.
