    MC 2018.5.0 Linking to oversized TIFF images requires a flip

    I have an interesting problem running Media Composer 2018.5.0 on Mac OSX 10.11.6 El Capitan.  When I use the Source Browser and link to a TIFF file that is larger than the project size, the TIFF file comes in flipped (I would have to apply the Flip effect to make it normal). (Linking to a TIFF file of the same size as the project settings seems to work.) If I use the Source Browser and import the same TIFF file, everything is correct, only linking is flipped. Other image formats and video formats seem to link properly, just TIFF is broken.

    Here is what I did:

    -In Photoshop, create a document with the size 4980x2801 and Save As (TIFF, no layers, Embed color profile: sRGB IEC61966-2.1; TIFF options: (Image compression (none), Pixel order (Interleaved), Byte order (Macintosh), Save image pyramid (no), Layer compression (Discard layers and save a copy))
    -Open Media Composer
    -Create a new user
    -Create a new project (1080i/59.94, 1920x1080)
    -In Source Browser, find the TIFF file created above (size 4980x2801) and link to it
    -Open the linked image in the Source Monitor and it is incorrect

    I'm curious if this happens to anyone else?  This workflow has worked for me in the recent past.

    Workarounds

    -Resize TIFF images to the project size (i.e. 1920x1080), but you lose the ability to pan and zoom using FrameFlex
    -Use a different file format (jpeg, png, etc.)
    -Import instead of Link to oversized TIFF images, but again you lose the ability to pan and zoom using FrameFlex, but Avid's Pan and Zoom effect may work.

    I can reproduce your issue, but only with those specific dimensions. If I create a 4K (3840 x 2160) or 8K (7680 x 4320) TIF file, the image appears correct in a 1920 x 1080 project. I also tried 3850x2166 (just to offset it a little) and that also worked.

    Do you see the same thing?

    I created a 3840x2160 TIFF file and linking to it does work normally.  So it must be related to the non-standard file dimensions I was using.

    Thanks for your help!

    Is that doable for you as a workaround?

    I'll report the issue to Avid, as obviously that shouldn't happen anyway; but I couldn't replicate it with other sizes so it might be harder to track down.

    Yes, I can use the workarounds.

    Re: MC 2018.5.0 Linking to oversized TIFF images requires a flip

    Yes, I am experiencing the same issue -- oversized TIFFs are flipped when I AMA link (or transcode), and are also upside down for me. 1920x1080p project. My workaround was to save the TIFFs at JPEGs.

     

    However, just 6 of 15 of a batch of over-/irregular-sized TIFFs imported flipped. The others imported fine. 

     

    I believe the upside down part is because those images may have been scanned upside down, and then were rotated within photoshop to be rightside up (I do not have unmodified scans to verify these 6 were the ones upside down).
