[QuadList] OT—How to reduce or eliminate moiré patterns from kinescopes?<br></font><br>
<div>Howdy from Elko, NV, heading west...</div><div><br class="webkit-block-placeholder"></div><div>While at an archive in Salt Lake City (that has Quad and nothing to play it on) I had a chance to run a monochrome negative kinney on the <b><i>flashtransfer</i><span class="Apple-style-span" style="font-weight: normal;"> yesterday.</span></b></div><div><br class="webkit-block-placeholder"></div><div>Surprisingly sharp, the scan lines in the kinney and the scan lines in the telecined image caused cyclical moiré, with color fringing on horizontal lines during the moiré cycle.</div><div><br class="webkit-block-placeholder"></div><div>Looked like a Nike Swoosh at the top of the moiré... and just beating of the lines below that.</div><div><br></div><div>I would think there were techniques developed to combat this problem back when Kinney's ruled television recording... and that there are ones developed for use with more modern
equipment.</div><div><br class="webkit-block-placeholder"></div><div>Defocusing the image does reduce the moiré, but also reduces the sharpness.</div><div><br class="webkit-block-placeholder"></div><div>I plan to play with changing the image size when I'm back in the office and set up again.</div><div><br class="webkit-block-placeholder"></div><div>Any suggestions would be welcome. I'd be happy to post results if anyone's interested. (Text and/or frame grabs.)</div><div><br class="webkit-block-placeholder"></div><div>Thanks in advance...</div><div><br class="webkit-block-placeholder"></div><div>Ted</div><br><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing:
