1920x1080 video imports at 960x540

Hi there!

Got a bit of a problem and after 2 hours of searching have not found a solution anywhere!

I have a HD video i need to add effects to in After Effects but when i import After Effects sees the file as 960x540, when the file is actually 1920x1080.

Using a 1920x1080comp and scaling to 200% shows quality loss compared to the original footage played in Quicktime.

Heres the files details:

Video
ID : 1
Format : ProRes
Codec ID : apch
Codec ID/Hint : HQ
Duration : 2mn 40s
Bit rate mode : Variable
Bit rate : 148 Mbps
Width : 1 888 pixels
Original width : 1 920 pixels
Height : 1 062 pixels
Original height : 1 080 pixels
Display aspect ratio : 16:9
Frame rate mode : Constant
Frame rate : 23.976 fps
Color space : YUV
Chroma subsampling : 4:2:2
Bits/(Pixel*Frame) : 3.082
Stream size : 2.76 GiB (99%)
Language : English
Encoded date : UTC 2001-01-01 01:01:21
Tagged date : UTC 2001-01-01 01:06:37

Any help or pointers will be very much appreciated.

Many thanks
Chris

Something tells me this video didn't begin life at 1920x1080 in ProRes 422.

How was this video shot? What camera and acquisition codec?
What application did you use to capture it, and what process did you use to capture it?
What other processing did you have to do to the video prior to exporting for use in AE?
How did you export the video for use in AE?

Unfortunatly as I wasn't involved in the filming/editing/exporting I can't tell you.

All I know is that it was originally shot on RED.

As the video plays fine at full 1920 in Quicktime Player, is there any way i can re-encode it for use in After Effects?

Also Adobe media encoder and Adobe Premiere also see the file as 960x540

Thanks for you help
Chris

First thing to do: make sure AE is fully updated if it's version 10 (Help>Update). It may solve the problem if you haven't done it yet.

In QT Pro, you can export a PNG image sequence; use all the bit depth you can. It'll be lossless.
Import the image sequence into AE, set the frame rate to 23.976 in the Interpret Footage settings, and you should be good to go.

The fact that you're using ProRes 422 implies you have FCP on your machine, so you can render back to ProRes 422 from AE.

You can also use FCP to export the image sequence for use in AE, if necessary.
