leopard latency & the IoHD…

[Jeremy Garchow]

I run mine @ 2, but I am still on tiger.

thank you jeremy… my machines had leopard already loaded when they arived and i’m hoping to avoid loading tiger.

i’ll hang in a little longer – maybe a leopard user will chime in.

again, thank you.

Did you try a negative number such as -2?

[E. Eric johnson iii]

actually no, i haven’t done that. i’ll give it a try.

thank you… again,

I’m working in Leopard on a MacBook Pro 15′ 2.33.

I’m not sure I understand your question because if you monitor video AND audio out of your ioHD everything should be in sync regardless of your playback offset in FCP. All the playback offset does is to synchronize the canvas to the external monitor. Mine is 5.
Are you looking at your canvas and listen to your ioHD audio outs or are you only looking at your external monitor for video and audio. If your doing the later and the footage is out of sync then it has nothing to do with the latency of the firewire device.
I did get caught thinking the ioHD has a problem with sync when I first time worked with Varicam footage shot at 25p over 60p. Everything was out by 2 frames. Jeremy here told me then this is normal too for 24p over 60p footage. So nothing to do with playback offset or any internal ioHD processing.

not sure this helps but hope it may give you a lead 🙂

hi carsten-

thank you for the post and the ideas. with the IoLA i had the same issues you wrote about, but was able to get that figured-out. it just doesn’t appear to be the case with my IoHD.

i’m going to walk away from the machine & look at it first thing tomorrow. maybe i’ve just looked at it so many times i can’t make heads or tails of the situation.

again, thank you for the post,

Are you saying that the audio and video are not in sync out of the ioHD or that your canvas and external monitor are not in sync?

[E. Eric johnson iii]

sadly, both are out of sync… or at least i’ve looked at it so many times i can’t tell anymore. i’m hoping a fresh look in the morning will make sense of the situation.

thank you for your input and i’ll report back in the morning.

So, what do you see this morn?

[E. Eric johnson iii]

hi jeremy-

sorry for the late reply, i had a client meeting this AM.

after that i went back to the edit system & did the following:

restarted the machine, then restarted IoHD, then opened FCP, double-checked my RT settings (nothing changed) and went with a frame offset of 5 and it appears, on the tower, to be in sync!?

i’d like to think it’s not operator error since i haven’t seen anything to point in that direction, but i have no other explanation at this point.

thank you for the time – now on to the sync with the MBP…

again thank you & glory to the cow.
