Hi Gary,

Just outputting 59.94 from the AJA – it’s the input that’s at 23.98.
Yes, we are using the 1 frame offset.

We’ve ended up doing a workflow with the BM Multibridge instead, and we’ve cut the AJA out of the loop.

Many thanks for everyone’s help 🙂

Hi Gary,

From the AJA website:

Anything in…

* 525i / 720p / 1080i / 59.94Hz
* 1080 psf 23.98Hz
* 625i / 720p / 1080i / 50Hz
* 1080 psf 24Hz
* 1080i / 720p / 60Hz
* 8-channel AES Audio
* 8-channel Embedded Audio
* 8-channel Balanced Analog Audio control

…Anything out

* 525i / 720p / 1080i / 59.94Hz
* 1080 psf 23.98Hz
* 625i / 720p / 1080i / 50Hz
* 1080 psf 24Hz
* 1080i / 720p / 60Hz
* 8-channel AES Audio
* 8-channel Embedded Audio
* 8-channel Balanced Analog Audio

If it’s not doing pulldown, how is it doing the conversions…?

Hi Shane,

The FS1 should be up to the task – it’s specifically deigned to do this kind of conversion. The only problem is that I don’t get a consistent offset, so there’s no way to compensate for it. What sequence and device control presets are you using to make it work? Could the fact that my sequence is 1080 rather than 720 be adding to the murkiness?

Hi Dave,

Thanks for the response. The FS1 is a universal converter:

It IS adding pulldown, the problem is that I can’t get it to be frame specific – i.e. I can’t get the layback to land at 01:00:00:00 (after bars/tone and the slate). And it’s not just an offset (which I could easily compensate for, it’s an inconsistent offset.
