Exporting 422 HQ + Alpha channel from After Effects CS5 = quality loss when paste into FCP
on Oct 1, 2011 at 9:28:52 pm

First of all I'm french so i apologize for any future grammatical mistakes.

Now for my editing configuration :
Mac Pro OS X 10.6.8
After Effects CS5
Final Cut Studio 2 suite (FCP Pro 6)

Here's the problem... I know it has already been discussed elsewhere but I haven't find any solution at this point.
I'm working on some motion graphics in AE that needs to be incorporated into an FCP timeline...
my FCP timeline have these settings :
- Apple Pro Res 422 HQ progressive
my export settings from AE are these :
- Quicktime Animation codec quality 100 RGB + Alpha
The output video is fine when played on Quicktime Player but when pasted into FCP the quality loss is visible.
I have then made a second export from AE with Apple Pro Res 422 HQ codec settings and when paste into FCP timeline, the result is perfect (i mean no quality loss) but the alpa cannel is gone by the way and so i can't composite it anymore with the underneath video (because of the black background of course)...
I'm pretty lost now...
If anyone have already been through this particular workflow i would be glad to know how...
Here's my screen capture
On the upper side of the picture you can see the Animation + Alpha channel
And on the bottom the Apple Pro Res 422 HQ export

In FC you can use the picture from the ProresHQ file and the Alpha from the Animation file.
Set the Prores picture (as Travel Matte Alpha) picture over the Animation.

Thanks but it can't be done this way...
Because if i use as alpha matte the QT animation as a shape for my nice 422 export well... guess what? I'm getting the pixellated edge of the QT animation... So unfortunately it's pointless.. :(
But thanks anyway ;)

[Enguerrand Bouillaguet] " I'm getting the pixellated edge of the QT animation."
That sounds to a wrong interpretation of the kind of Alpha Channel.
Are you exporting "Pre-Multiplied" from AE?
Have you checked the Alpha options in FC?

Pre-Multiplied from AE
Where do you find Alpha options in FCP ?

You should not be getting that kind of degradation with Animation.

Are your frame sizes set correctly? Field order (if any) ?

Anyway..if you can find an upgrade to Studio 3, you can use ProRes 4444, which has support for Alpha Channels and keys in real time in FCP. I would not pay for an upgrade to Studio 3, though, as with the arrival of FCP-X, its a dead product.

The weird thing is that there's absolutely no trace of image degradation in Quicktime player the quality loss happens only in FCP, so what the hell ???

By default FC works with "Strait Alpha", so if you can export from AE that way, better.
In FCs Browser > Alpha column, you can change the clip Alpha (Strait/black/white).

It should look fine in FCP.

Are you Fully Rendering?
View on external monitor?

Set the Alpha as Black, lay the clip again in the time line and render with the Canvas at 100%.

More and more disturbing
Thanks Rafael but Alpha switches in FCS browser have no influence whatsoever
I've tried different methods of export in animation codec
1° Animation Quality 100 Premultiplied RGB+ Alpa Field render Off
2° Animation Quality 100 Straight Unmatted RGB+ Alpa Field render Off

When i paste it into the timeline both renders horribly in m ProRes 422 HQ progressive timeline.
But If i create a new setting in ProRes 422 1920x1080 Upper Field scan (interlaced) well the lower third from AE renders well...
And if i create a new timeline and paste in the AE rendered file FC wants to adapt the timeline to the video file settings by creating an animation codec timeline which in the video renders well too...
Anyway it seems I can't composite my motion graphics from AE in a ProRes 422 HQ progressive... I'm going insane !

You need to render out frame size and rate and fields to MATCH your FCP sequence.

@Chris Tompkins

OK then what settings do you use in AE export dialog box to match a 1920x1080 ProRes 422 HQ progressive timeline in FCP and be able to keep the transparent background since Pro Res 422 HQ doesn't handle transparency ???

Obviously the Quicktime Animation Codec is the most used by any motion designer to render out their sequences from AE... So why my FCP is messing up with this particular codec when paste into a progressive timeline and don't when paste in an interlaced timeline ???

You don't have to care that the sequence codec (ProreHQ) do not support Alpha.
Is the Animation file who needs the transparency.
Drag it to the Prores sequence and will work. (WHEN FC asks you to confirm the sequence settings to the clip, SAY NO).
If clip and sequence match in time-base, size, field order, etc, better.
No need to re-time, re-scale, deinterlace, etc.
But even if they do not match all the setting, the Alpha channel will work.

Like he said, use the Animation Codec but match everything else.

1920x1080 24p or 30p or what ever your fps is.
Drop in above your video. Render.

Make sure the Animation files shows as NONE in the Browser.
FC may be checking them as UPPER.
Make sure FC identify properly anything coming from AE.

I know this thread is long dead, but for all those people searching through google for the answer, this is it!

Make sure to right click on your file in the FCP Browser, go down to Item Properties, Format. From there, find Field Dominance. Right click on the options it gives you (None, Upper, Lower, Not Set) and select None.

Make sure to drag this into your timeline AND DELETE the existing footage on the timeline if you have already placed it. Render and your problem should be solved.

Hey Tanner.

I had the same issue, and I solved it changing the Gamma Level in Format Properties.
