IO Hd Delay
by Jorge Goizueta on Jun 24, 2008 at 1:54:59 am

Hello to everyone

Im working on a sd project using ntsc APR HQ codec w/ MBP 2g ram 2.4 ghz core 2
ok my problem is that my external monitor has a delay compare to my viewer on final cut if someone experiencing the same problem or it is something on my system

thanks in advance

p.s im sorry for my english

Check your frame offset.

Final Cut Pro > System Settings > Playback Control tab

Try a setting of 2 from the default of 4.

If it 2 isn't right, set it until you see it's matched.

Are you dropping frames?

Does the video play smoothly just delayed?

Are audio and video in sync?

Have you tried a negative value on the frame offset?

Have you tried a larger value on the offset?

Is your storage fast enough?

Does your easy setup match your captured footage?

Are you dropping frames? NO

Does the video play smoothly just delayed? YES

Are audio and video in sync? YES, But only on the viewer on fcp and if i switch the audio trhu the io the viewer gets out of sync

Have you tried a negative value on the frame offset? yes

Have you tried a larger value on the offset? no im going to try this

Is your storage fast enough? its a graid2 connected on the spresscard bus

Does your easy setup match your captured footage? yes


thank you again i really appreciate your help

[Jorge Goizueta] "YES, But only on the viewer on fcp and if i switch the audio trhu the io the viewer gets out of sync "

In order for audio and video to be in sync, they must play out through the same device. In your case, that's the ioHD. You can't play audio out through your computer and video out the ioHD and expect it to be in sync. Make sense?

Hit control-q.

Choose the proper easy setup.

Try again.

You don't have any other firewire devices connected to the bus, right?

If this doesn't work, try uninstalling and reinstalling the drivers. Make sure your firmware is up to date as well.

TBH I think the delay is just a firewire processing delay problem. The Avid Adrenaline suffers an even worse firewire related 'delay' artefact to the point of Avid now changing the hardware. No amount of firmware updates ever resolved the problem.

Personally I see any firewire connected Io 'BOB' as a device to do playouts to VTR or to output to a client monitor. You need to be cutting from the viewer and delaying the Io audio to match and accept that while it offers fantastic connectablility, it isn't perfect.

We use Io's and Kona's here. The PCI connected Kona's dont have this problem and can be set to a delay value of'0'.

Just the way it IMO...

Sorry guys, even with the standard io devices, the delay was not half a second. The ioHD has even improved upon the latency. There is no way that I hit play, then a half second later, video and audio starts on my external monitors.

There seems to be a config issue here. Yes, firewire has latency, but half a second is a lot.

I agree. 1/2 a Sec is more than a FW latency issue- there is something else going on.

what Quicktime and OS are you using?

No other apps are running?

Are you sure your media AND renders are on the GRaid?

[Jorge Goizueta] "Right now i start a xdcam ex project and dont has the latency its super weird its only on a sd project :( "

This further makes me think there's a configuration issue.

In your SD project, make the ioHD control panel available to see while you have FCP open. FCP has to be selected/active, make a new sequence, drop in some footage and then play it back.

What does your control panel say for frame buffer and what does it say for your outputs?

Unfortunately Jorge, this is the nature of the beast, and the beast being firewire. Unlike the Kona devices... when you go to view your output on an external video monitor, the Firewire output must be converted into a standard NTSC or PAL video signal. This is accomplished by using a DV camcorder, VTR, or converter box (such as the AJA IoHD) as an intermediate link between your computer and your video monitor.
When viewing video with the External Video option enabled, the computer's built-in speaker is disabled (or at least should be) and the audio will play out of the DV device used for conversion from FireWire. You should also know that this external audio is synchronized specifically to the external video coming out of the same converter, and that there is a delay in the sync between video displayed on the computer monitor and audio coming out of a DV converter box.

So when you see a delay between what is on your Final Cut Pro output viewer and what is being recorded/outputted, this is normal. This is because there is a delay in transferring the data via the firewire cable into a video source. All will still function properly and everything should be fine when you play back the master tape.

I know its quite the annoyance but I have never seen such a workaround for this without adhering to a single output source or using a non firewire device (ie. Kona). Hope this helps.

Unfortunately, I'm having the same problem. I'm not buying the "nature of the beast" theory. My old io works perfectly using all of the same connections (firewire, audio, ref) with my system. The ioHD has the 1/2 second playback delay - but the problem is intermittent. Sometimes sync is right on the money. This delay is also happening when capturing SD video/audio. When I see the delay, I need to close out of the capture tool and re-open until it works. Again, my old io box works perfectly.

Im sorry for the delay

MBP 2.4ghz, 2 gig ram, gtech raid2, os leopard w/ latest updates same as QT.

Note: The delay is only on an SD project and not always, with hd i dont have the problem no even with a xdcam timeline everything its very accurate on hd.

[Jorge Goizueta] "Hi jeremy here are my spec "


the build of the driver is incorrect- the 5.1.2 driver is ONLY for users running leopard- and your specs said that you were on 10.4.11

from the aja site

This driver version has the same feature set as version 5.1.1 and is only meant to address possible issues for users working with Io HD when operating under OS X 10.5.3.

this will also mean that you have to update the firmware in the unit again also.

Is it an A/V sync issue or just a delayed output?

It's an intermittent sync issue with audio and video.

Ok, A/V sync is entirely different from FireWire delayed output. And I can tell you I also have been struggling with this issue on 3 different ioHD boxes since the initial release, and its not caused by the driver/firmware version either.

A few steps that I always take to help with the sync issues until AJA takes can address this problem.

- Check that all equipment is properly Genlocked, including the ioHD
- Verify AJA audio output/input is not selected in the "OS X system preferences" (change to line or built-in input/output)
- Be sure to power up AJA before powering up computer
- Attach AJA to your system bus and not a firewire ExpressCard or Firewire pci card
- Recapture any previously captured video to verify its capturing in sync
- Playback from timeline to verify A/V playback sync
- At last test your quicktime playback with AJA VTR Xchange, to rule out any Final Cut configuration issues

Yes, Lawrence that is a seprate issue and you should start a new thread for that as Jorge is having different problems.
