    Frame Flex Issues with spanning 4K clips

    I've found a bug that i've been able to repeat and was wondering if anyone has had the same issue or found a work around.

    We're using a single Sony FS7 shooting 4k for master interview footage, we punch in using FrameFlex to create a CU B angle.

    When I'm transcoding a spanned 4k clip with frame flex applied, at the marker that indicates the span from one clip to the next, the frame flex unapplies itself. The clip will be punched in, and at the span it punches itself back out to the entire wideshot. This isn't a one time thing, it repeats itself anytime that i'm transcoding a spanned 4k clip. We've tried numerous things to see if it would fix the issue:
    -Disabling LUTs on the clips
    -Foreground and background transcodes
    -We encountered the issue in 8.4, we tried upgrading to 8.5 but had no luck

    Has anyone else had a similar issue?

     

    Here are project settings if anyone needs them:

     

    23.976p NTSC

    YCbCr 601 color space

    Raster: 720x496

    We use these settings because its allow us to transcode the native video files down to 14:1 MXF.
