    Hey,

    I've been recording some shots where I have vertical, colourful and glitchy stripes. I have pushed the ISO to 1600 so you can see them better.
    the black shade has well been done and I didn't have any warning message on the RED.

    you can find a R3D snap here: https://we.tl/Jud4Fin1pJ


    Any idea of how to fix it ? And where it comes from ?

    Cheers,

    Yes and if you increase the isos even more you can see them very clearly on the whole picture.

    Does this happen with all your lenses? Check your lens elements for anomalies. Did you ever cleaned the sensor? Try replacing the OLPF and check for the same pattern again.

    Looks like a bad sensor to me... This was my E-W pushed to 12800 and +8 exposure adjustment.

    That's a good question, I'll be looking through our footages later on and will perform some lens tests.

    It's a problem that seems to happen rarely. We did a lot of shoot with the EPIC-W that have gone perfectly well, including the same lenses.
    I haven't cleaned the sensor neither replaced the OLPF.

    I have used the auto black shade and had some with and without the beta, need to be confirmed.

    Thanks Brandon for the files, we have usually the same images as you (fortunately...)!

    Yea, mine is exactly the same thing. Already contacted RED and sent log, R3D's, etc. Will let you know what they say, but my guess is that my cam is going to RED.
