Hmmmm,

Since downloading & installing 12.5.1 HD Suite on my HDe, after capturing HD/SD SDI pics with embedded audio, I have clips that have around 6 frame audio delay.

Using ProRez422 HQ codec like I always have been. Never an issue with previous versions.

Tried all the preference setup combinations without solving the problem.

Any thoughts please.
Thanks
David Issko

What format (resolution and framerate) are you seeing this problem with, and what input are you using? I´ve tried PAL 625 and 1080, and it seems good at least on Kona3 systems; I will try it on LHe next.

Thanks Scott,

Thanks for your prompt reply

Hi Floh,

I have been shooting on my Sony V1 HDV camera for the past year in 1080 50i and capturing to the Media 100 in ProRez422 HQ in HDSDI from my 1500 HDV edit recorder. No issues until 12.5.1.

I know what settings I need (not that anything has changed that much in 12.5.1 anyway) and I cannot seem to sync the audio. Easy but frustrating fix in unsyching the clips, moving the audio clips to obtain lip synch, trim the excess and edit away.

Cheers
David Issko

Not sure if this is connected to my sync problem, but I use XD SD with embedded audio via SDI, and nearly every time I digitize, I find several clips with out of sync audio. Once I find one clip out, then all the clips that follow will be out, but by varying amounts. Anyway I've just become used to checking the clips and batch re-digitizing all the problem clips. This slows down the process but always solves the problem for me. Certainly beats trying to lip sync everything. It's a shame though because I was thinking that 12.5 might solve my problem. Maybe it will.

Hi Murray,

My audio sync issues just started with 12.5 - never encountered it before but I will be carrying out more tests to see if it is possible codec related. I never rule anything untested out.

Hope you sort out your issues before long.

Thanks for your input, most appreciated.
Cheers

I can't get HD with embedded audio into my version 12.1.1 with the non Intel G5, only SD, I can get the HD video in but not the audio. Am I now to understand that the new version 12.5 will take HD with embedded audio through SDI or will I need the new Intel G5? An audio delay I could manage until they fix it but I need to know before finalising a workflow for the EX1 camera. Anyone know the answer please, maybe Scott?

The HDx boards are PPC only, and they take only embedded audio via SD-SDI. If you need HD-SDI with embedded audio you either need an Aja PCI-X board for your G5 or an Aja PCI Express board for the last series of G5s or for the MacPros.
