Transcoding in Compressor between Aspect Ratios
Hey Everyone,
I have some Uncompressed 8-bit NTSC 4×3 footage that I’m looking to upres to DVCPRO HD, and I’d like maintain the 4×3 aspect, adding pillarboxes on the sides of the DVCPRO HD upconversion. Can you tell Compressor to do this, rather than have it stretch the 4×3 clip to fill the entire 16×9 space? I know there are all kinds of additional problems that probably have to be considered because of the pixel aspect ratio differences as well, but I’m just curious if Compressor can do this, or if I have to go through FCP. Thanks!

Easiest way to do this is to make a anamorphic version of the timeline you now have so all the video settings are the same and then just click the anamorphic button.
Than place the 4:3 sequence in the new timeline and you will have a pillar box version. Send this to Compressor and get what you want. the HD footage will be 16:9 but your original footage will keep the 4:3 look.
NOTE: Compressor 3 is greatly improve with up-converting now that it has Optical Flow built in but get ready to wait. You would still want to do the above.

Thanks Msacci. Good Info. But I was just curious if you can do this totally outside of FCP. I want to convert the entire unedited captured clip, and would prefer to work in FCP while the encode is going on.
Thanks again for any additional input anyone may have.

If you are using Compressor 3, its easy.
Just drag the setting for DVCPRO HD from Advanced Format Conversions to your clip in the batch window. Then in the Geometry tab of the Inspector, select 4:3 in the Output Image Inset (padding) inset section.
I don’t think you can do it properly with earlier versions of Compressor. I used to use AE for this, but Compressor 3 does it nicely.
