  1. I have the same problem but with an imported clip that was Apple Intermediate Codec form. When I exported to H.264 (so problem occurs with that too!), the “blueness” only affected the clip that was imported.

    So I converted the clip to ProRes 422 and exported again (using the queue method), it seemed to work.

    However, the first time I queued with the AIC clip, it worked. It was only when I re exported it that it seemed to not work.

    So is it the imported clip? Is it something to do with the rendering? I was really enjoying APP until that final delivery part.

    Anyway, thanks for your workaround suggestions. It helped me at least continue working.

  2. Chris,

    I’ve had intermittent problems with this as well. I’m glad the ProRes switch seemed to alleviate the problem. This is really the only workflow snag I’ve found in Premiere Pro to date.

    I’ve forwarded the information to the After Effects and Premiere Pro team in the hopes that they can address it in a future release, or at least shed some light on the problem, but have not yet had a response.

    Good luck with Premiere!

  4. Please try this workaround and let us know if it works:

    Apply the Crop effect, but leave the properties at the default so that nothing is actually cropped.

    Does this prevent the blue problem?

  5. Todd, You are correct. Applying the Crop effect to the rendered AE clip within the PP timeline does eliminate the problem. Thanks for the follow up and the solution!

  6. No problem. Sorry it took so long.

    Here’s a document with more information:

  7. Though it is certainly an error of some kind with the Animation codec from After Effects, I have found that if you simply add an underlying layer of opaque footage under the entire section of footage that you intend to export, there won’t be any problem. I’d recommend a black gif or jpeg for obvious reasons.

    I have no idea why this prevents the glitch in the out put however and I merely stumbled across this work around as I initially thought premiere was reading the alpha channel incorrectly or something.

  8. Gerald,

    If you follow the link from Todd Kopriva’s response, Adobe has recognized it as a bug where the color channels are read out of order. Adobe’s recommendation is to add the Crop effect to the footage in PP and set your crop window to the full size. This effect forces the channels to be read correctly.

  9. Thanks for the post . Just converted from FCP and had this happen.

  10. I’m glad the post was helpful. Welcome to Premiere Pro!

  11. FYI, I’ve found that rendering a preview of the affected area and then exporting with the “Use Previews” option selected is a viable work-around.

  12. Dan, Thanks for the tip. That seems like it would work as well!

  13. It appears that you can bypass the problem by exporting the clip by clicking the box matching the sequence setting in Media Encoder.

    But I can’t admit I have found a workaround to preserve the desire output format/codec.

  14. So glad I found this article! I am using PPro CS5 and had this “blue bug”, I have been pulling my hair out! But you were right, it was the Animation Codec.. BUT it wasn’t from AE, it was a clip I rendered from a Digital Juice DVD. I checked the settings and it defaults to the Animation codec. I just re-rendered with a different codec and replaced the clip in my sequence and it worked perfectly! Thanks for the tip, you saved me a LOT of hours and frustration!

    Cheers,
    Dan

  15. Dan, I’m glad I could help!

  16. I found i had this problem with certain clips not necessarily connected to exports from AE. Initially I placed black layer below clip. This worked in many cases but not all. I also found that if I added a non-adjusted RGB effect to clip that would often cure it.

    I have since seen an Adobe recommendation to add a clip effect without any parameters set as a work around. They are aware of the bug and I expect we will eventually see a solution.
