    Media Composer 2018.12.6 Issues

    Hi there,

     

    I couldn't find a thread dealing specifically with issues found in 2018.12.6, so thought I'd start one.

     

    We have noticed an issue with the Safe Colour Limiter in 2018.12.x , I believe it is at least from .5 and up.

     

    When you have the Safe Colour Limiter applied, and you have 422 enabled (ticked) it appears to introduce artefacts at the top end of the signal, it appears to be crunching it rather harshly, and producing noticable break up (bit depth?). This is usually on very saturated images/graphics, and most noticeable in the blue channel.

    The same seqeunce, with the same media and SCL effect in v8.5.3 does not produce the same artefacts, it is clean. Have tried recreating effect from scratch.

    If you turn off 422, it will disappear, but we have historically had it on with no problems in the past.

    Cheers,

    Hello 

    We have had this reported but could not reproduce it on our end...  Could you send us some sample media, even if it's only a jpeg that will exhibit the problem?  I also need to know what your Safe Color settings are set to. Also as much about your comouter and setup as possible.

    Email me directly

    and ref this bug which is still open as well...MCCET-2549

    Is there any sample footage for this?  We are running 2018.11 and 2018.12.6 on Mac and have not seen this.  Would really like to see a screen grab showing the issue.
