  Workflow/Pixel Aspect Ratio CS3 , AE 6.5, HVX200

  Posted by Alyer Breau on October 9, 2008 at 8:35 pm

  Hi,

  Working on a project that was shot on the HVX200 960×720 23.976fps (P2). I want to do some graphic work on the same machine which is running AE 6.5. AE wasn’t upgraded. I’m having some pixel aspect ratio problems in exporting from PP to AE. How should I export from PP to AE? And then how should I render out my final comps out of AE. Any advice on the best quality and pixel aspect ratio would be highly appreciated. Do I need to get a plugin or codec for AE? Thanks so much.

  Your pixel aspect ratio issue will be there even after the upgrade.

  I usually export in square pixels (Quicktime Animation is one option), since that’s what you would want to be working with in AE. Just remember to change your frame size to 1280×720 in the export settings as well.

  If you already exported as 1.33, just change your composition setting to 1280×720 square in AE, all should be well (it just takes AE more overhead to convert the aspect ratio in my experience).

  Also keep in mind that Premiere will need significantly more CPU power to keep up with QT animation exports from AE / VS native P2.

  There is one excepetion, and that is if you are keeping P2 all the way to export to P2 as the final format. Then you should keep your aspect ratios the same all along, just change the preview in AE to convert aspect ratio. The 2 problems with that method is that the preview will be pixelated, and you will be limited to 8 bits in color corrections.

  Thanks, Vince.

  Now, I just found out that the deliverable is going to be in standard definition. The dub house will not take a file and will only accept NTSC 4 x 3 on digibeta, dvc pro, etc. Is there an easy conversion process using Premiere on a pc? This PC workstation has no other encoding applications on it except adobe media encoder.

  Thanks again, for your help.

  You mean the dub house won’t take 16:9 or the people you are giving this to want 4:3 ?

  I would certainely push 16:9 on the client if you can, or go to a different dub house if they are the issue…

  Anyway, assuming SD 4:3, if you have already edited the project, just import it inside a 4:3 SD project. The format will depend on what you are exporting to. If it’s DVCAM, then create a DV project, if it’s P2, then create a DVCPro 50 project.

  Then you have a choice to either fit to frame (leaving bars on top and bottom), or crop the sides, thus filling the 4:3 frame. If the client wants 4:3, cropping the sides and filling the frame would be the way to go. You may have to keyframe an horizontal pan if the framing is incorrect at times.

  Going to After Effects, SD becomes 648×480 in square pixels.
