Posted by Rokas Gecas on June 27, 2007 at 4:49 pmhere is the link to see what i mean
https://www.zshare.net/image/2455132edff56f/i don’t know what i’m doing wrong. first view is composition window and second view is movie preview window (it pops up when you double click on video file). see the difference? the problem is that it renders like first view. i tried to render as mov dv and microsoft dv codecs. same results. composition is pal d1/dv preset. file of cause is pal dv avi. please help

June 27, 2007 at 5:45 pmMy suggestions would be to double check your footage interpretation. If you want your footage de-interlaced, make sure that you have the correct field first in the interlacing section. Also make sure that your composition has the correct pixel aspect ratio.
I would also recommend rendering out to Lossless.

June 27, 2007 at 5:52 pmpixel aspect ratio is correct. i’m rendering to lossless format.
sad but i don’t know what is “footage interpretation”. and undestood nothing in your second sentence. what i’m doing is creating composition, draging dv video in it, adding few effects on that avi and making movie. that’s it. can you explain a bit more about footage interpretation, de-interlacing and “correct field first in the interlacing section”.
thank You for helping!

June 27, 2007 at 6:16 pmDid you create a composition setting up the proper size, frame rate, length, etc… or just punch the new comp button, hit ok and drag your footage in? By doing so it just uses the last settings that were used which could be anything.
If you have DV footage and are planning on outputing the full size back to DV or anything else, you might drag your footage onto the “new comp” button. This will create a new composition the same size, length and framerate of your footage.When you are all done with your comps, then choose “composition, add to render queue” and then set up your output options. Then render.

June 27, 2007 at 6:22 pmAssuming that your source footage was interlaced, AE will attempt to de-interlace it by interpolating the fields. It’s pretty good at guessing the correct way to do this, but you can tweak a couple of the settings to double check it.
If you right click your footage in the Project Panel and go to ‘Interpret Footage>Main…’ (or press cmd-f/ctrl-f with the footage selected) it will open the Interpret Footage dialog.
Under the Fields and Pulldown section there are options for separating the fields (deinterlacing) and removing pulldown. You probably don’t need to worry about removing pulldown (especially since you’re dealing with PAL) but you should see what the setting for Separate Fields is. Generally it is my understanding that PAL will be Upper Field First. If you’re not resizing or moving your footage in the AE comp you might be able to change this to ‘Off’ and get better results. If you find it works better when you separate fields, then you might try using ‘Preserve Edges’ to see if that helps as well. You can check the pixel aspect ratio of the footage (as opposed to the comp) here as well.

June 27, 2007 at 7:34 pmTHANKS A LOT!!! turning of separate fields “off” in footage settings helped. tips about creating composition where usefull to. once again thank you guys. you’ve saved my life 🙂
