Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)
Is it only on one mag or across multiple mags? Reinstall the latest release firmware, reformat via a "secure format," then re-blackshade doing a manual calibration at your current exposure. Make sure T/E text is green before black shading. Then record and see if that line still persists. If it does, file a support ticket.
