Another AJA need
Seems that the playhead on a clip like my narration, does not line up with the waveform when playing the clip. If I step through the clip, then all lines up. Just seems that when I play it, the playhead is about 10 frames ahead of the sound. Happens in the viewer and the canvas. Really annoying when marking by sound.
what’s up with that?

It’s due to the latency with outputting audio and video via firewire. You will find it corresponds to the number of frames delay you have set in your preferences.

Okay, but I need the delay to have the canvas window and the main viewing monitor match up.

There’s an inherent delay in a firewire based capture device. AJA has cut this down to 4 frames. You need to go into the File > System Settings and then hit the playback control tab and change the frame offset to 4. This way your timeline, canvas, and external monitor should line up. You will not be able to get rid of the 4 frame delay between you trying to edit to music or cut on your timeline. You will get used to the delay.
There should be a special term coined for this delay, but there ain’t.
Ain’t, ain’t a word.

PS I hate to say this, but the aja manual should be your friend. A lot of the things you are discovering are explained there.

I just downloaded the manual. The other one was an install book. My audio is still not right. Must call a tech. I will read the manual. The delay thing when editing with a waveform drives me crazy/

It shouldn’t be that bad, Bob. 4 frames, although you feel the lag, is not terrible. Maybe you have some other issues with your system. Do you have any other firewire devices hooked up to your machine?

I did have a Maxtor 250 gb drive hooked up but have pulled it after learning that AJA wants to be the only Firewire device on the G5 unless I get a card. But, for me a 6 frame offset is needed to have the NTSC monitor and the canvas monitor match up. Right nowe my problem besides the audio out of FCP not being right is I cannot get deck control. I have a 422 cable from the Aja to the Sony 1800 and I cannot get the two to talk to each other.
Looks like a call to Aja is in order.
Thanks

Do you have all of the latest drivers and firmware?
The drivers are up to version 2.1

Installing is easy.

Yes I do (on the drivers). I talked to a tech at AJA and he feels tha cable may be bad. BTW I just learned that the name is pronounced AY-JAY Heard it so many ways.
Thanks for the help

You can have multiple firewire cards on your system, as I do on a G4 system and it works just fine. BUT remember, AJA IO has to be on a card by itself! It needs the ful bandwidth to operate.
