    Vertical Artifacts on Export - MC 7.0.2 PC/Mac

    Has anyone else seen this? We are having some very difficult issues when exporting files. Specifically, Media Composer 7 is creating vertical banding artifacts on export whether we export from PC or Mac.

    This is happening with a variety of original media. We usually shoot either PMW-F3 (XDCAM EX 35Mbps), PMW-F5 (XDCAM HD 50Mbps / XAVC HD 100Mbps) and Canon C300 (Canon XF 50 Mbps) and have seen it happen with examples of each.

    This was not a problem in MC 6.5.x and earlier. In fact, we installed a demo version of MC6.5.3 to test it out and no artifacts were present using the same source project and media files. Conversely, I installed MC 7.0.3 to see if the problem was fixed in the update; no dice.

    Normally, we export footage as DNxHD 175 (23.98fps) at 1920x1080 from the original clips for our graphics department. They are the ones who caught this problem initially.

    Please see the examples below. It is especially noticeable in areas adjacent to fields of solid color.
