Lossy compression
Hi All,
I’m putting together a workflow for a project and will be capturing with a Targa Cinewave card & codec to edit in FCP 3 and compositing in AE, all of which I’m used to doing and am on top of (mostly, anyway!)
I wish to lay off masters to digibeta at a facility house this time so that I can do a nominal on-line and sound dub. It’s not for broadcast, but the client wants to see/visit a facility house. Now, the facility house has suggested I render my final export out as an Avid Meridian codec, which I’m OK with in principle. However, capturing with a Targa Cinewave codec, then rendering to an Avid code makes me nervous that there will be a loss of quality as the files are rendered into an entirely different codec.
In this case I hope to go
IN: TARGA CODEC,
FCP EDIT: TARGA CODEC (so no re-render),
“EXPORT” from FCP: Linked FCP videos, which can be picked up by AE without re-rendering.
AE: compositing/effectsEXPORT/RENDER from AE: AVID CODEC, carry to facility house on FW drive.
layoff to digibeta master from the facility house AVID after basic conform to standards.
So, basically – only one change of codec throughout. I don’t know the AVID codec and what options it it has, as I’ve never had reason to deal with it directly before, but any advice on whether there is likely to be a problematic loss of quality would be appreciated.
regards

Avid has 1:1 “uncompressed” (8-bit) on it’s Meridian line, so you should be fine. However, I’m not sure how you would [doogal] “EXPORT/RENDER from AE: AVID CODEC, carry to facility house on FW drive.” I’m sure this can probably be done, I’ve just never done it, and I must not have the proper codec loaded. If you do have that codec, then it should work out. I’d do a test on a short clip and send it to them to make sure everything imports properly, and looks good.

This is unconfirmed but the Avid Meridian codec is broken in QT7 from some of the posts I have read.
You may want to do a post search.

Hi,
Thanks for the advice –
In fact, I had at this early stage assumed that the avid codec would sit OK with an After Effects Render, and from what Bryce says, this aspect is something I now need to get sorted before committing to any workflow.
However – in theory it currently looks feasible, which is a start.
With thanks
