    Hi, all…

    If someone could watch this video ( https://s129.photobucket.com/albums/p220/josephnathan/?action=view&current=NTSC_Comp.flv ) and take a look at the last second-and-a-half. There is some blue “noise” or artifacting going on that I can’t figure out where it’s coming from. When I go back through the project, it’s not there.

    I rendered uncompressed 8-bit QuickTime. Took 90 minutes (for 5 seconds of video!). Could that be because I have two nested comps and it renders each comp individually? Sorry, still learning AE. Takes at LEAST 90 minutes for DV/DVCPRO NTSC, Animation, and uncompressed 10-bit. Kinda frustrated. Didn’t think it was that complex of a comp to rener. The map is created in Illustrator and brought over as a comp so I can control each layer. Hmmm…

    Thanks for any help in advance.

    Looks like compression errors. This usually happens when the data rate is too low and there is too much change in the image (your pullout is extremely fast compared to the rest). Might also be some simple clipping glitch (if your map is a 3D layer), but that’s less likely.

    Thanks to those who responded so quickly.

    Mylenium…How can I change the compression/data rate? The map is a 3D layer. The pull-out has to be that short because I can’t really have a 4-second pullout just to make it balanced with the rest. Again, sorry if I’m not understanding anything correctly.

    David…I’ll check to see if it was an erroneous 3D layer sticking out. The only blue I have is the background solid (which is not 3D…everything else is). Unfortunately, I don’t have a website that I can host it so you can step through it…but I’m uploading it to yousendit.com. You can download it there, and hopefully step through as a QT movie. Best I can do. Here’s the link: https://download.yousendit.com/1AD456DA7C11A9B4

    Thanks again for your speedy replies…I know it’ll make me a better AE user.

    Getting the compression right is not easy and usually requires some experimentation. I can’t really give you any sensible pointers as I barely ever use FLV (I do not particularly like all Flash-related stuff). Perhaps someone else can be of more help.

    OK, all…I’ve gotten some real good advice, thanks.

    And just to clear something up…I usually don’t work in Flash, either. The only reason that 1st video is a .flv is because that’s how Photobucket compressed it. I always export for QuickTime. The original file was rendered uncompressed 8-bit for Quicktime. I know nothing about flash movies or compressing for flash. That’s why I reposted on yousendit.com because they upload the file exactly as is…not change it into something else. I don’t have my own website to post videos to (unfortunately) 🙂

    Again, thanks to all that helped…I’ll be spending the day today trying to apply everything I’ve read and will post when I find the solution.

    Hey, Bogie…thanks for the e-mail.

    Yeah, it was foolish of me to ask why it took so long to render. Shoulda known better. I’ll try the blur…is that the DOF effect under “3D Channel”? There’s no lights on the comp…I just created the shadows by duping the spheres and using an effect to tilt them. The spheres are individual layers and were created in Photoshop (circle with gradien fill/pattern).

    What I am trying now is bringing the map’s 20 layers in as footage (flattened) rather than a comp and just have that illustrator file, and 4 photoshop tiffs (the spheres/shadows), 1 text layer and 1 .mov (the flag). Hopefully that will help.

    -steve=o, Thanks for your reply.

    Nothing under “map” layer”
    Not duplicated.
    Road lines are not merged…seperate illustrator layers. I could merge them, which i am currently experimenting with.
    I re-posted the movie in a steppable format on yousendit.com…the link is in my second post.

    Thanks for the advice! I am truly thankful for these types of forums where everyone is willing to take time out of their busy day to help others. Hope I can get good enough where I can repay the favors!

    Cheers,
    Jonathan

    UPDATE:

    Bringing the map in as a flattened layer really helped. Frames only taking about 4 seconds each rather than 2 minutes each. And, I don’t have the blue “noise” anymore! WOO-HOO!

    Thanks again to everyone.
