Aviator

A new SVT-AV1-PSY release, plus new filtering options for telecined &amp; interlaced videos!
 First, Aviator changes:
 <ul>
 <li>Updated to GNOME SDK 46</li>
 <li>Added a deinterlace toggle for converting interlaced source media to progressive scan</li>
 <li>Updated to FFmpeg 7.0 &amp; SVT-AV1-PSY v2.1.0</li>
 <li>Progress bar indicator now features fractional increments to better indicate progress for slow AV1 encodes</li>
 </ul>
 SVT-AV1-PSY (v2.1.0) updates relevant to Aviator:
 <ul>
 <li>Preset 6 is now redundant with Preset 7. We won't skip it in the slider, but just be aware they're the same now</li>
 <li>Presets 0, 3, 5, &amp; 6 have been sped up by 12-40% with little to no quality penalty</li>
 <li>Presets 11 &amp; 12 feature up to 2% more compression efficiency</li>
 <li>Additional ARM optimizations</li>
 <li>Lowered the minimum preset for 8K encoding from 8 to 2</li>
 </ul>

Exciting SVT-AV1-PSY improvements and an awesome audio fix that's been a long time coming!
 First, Aviator changes:
 <ul>
 <li>Migrated to libadwaita 1.4+ widgets</li>
 <li>Fixed the notorious 5.1(side) audio encoding error</li>
 <li>Minor code clean-up</li>
 </ul>
 SVT-AV1-PSY (v2.0.0rc2) updates relevant to Aviator:
 <ul>
 <li>Updated variance boost to improve encoding efficiency and eliminate rare flickering artifacts</li>
 <li>Variance boost refactored to work with native q-step ratios</li>
 <li>Preset -1 is twice as fast, &amp; presets 0 through 8 are up to 28% faster</li>
 <li>Presets 9 through 12 are 1-4% more efficient</li>
 <li>Additional ARM optimizations</li>
 <li>Bug fixes</li>
 </ul>

TL;DR, mostly SVT-AV1-PSY improvements. But still exciting, nonetheless!
 Open GOP toggle has been renamed to oGOP
 Speed -1 and -2 are now supported with a warning when you go below Speed 3. Speed -2 can take over 8 hours for a minute of video on a Ryzen 9
 New "Perceptual Tuning" enables some new SVT-AV1-PSY features by default to improve visual fidelity at the cost of metric scores
 "-mapping_family 1" is now enabled in libopus, so surround encodes will benefit from Opus's multichannel optimizations
 Modified SVT-AV1 defaults, notably re-enabling temporal filtering by default

Today, we have a very exciting development - Aviator has switched to an in-house custom fork of SVT-AV1 dubbed SVT-AV1-PSY!
 Featuring development efforts from BlueSwordM (author of the previous custom fork), myself (Gianni), and others, this change will enable us to have much more control over the encoder's development so that it aligns most effectively with Aviator's number one priority: visual quality.
 So far, SVT-AV1-PSY's most noteworthy feature is a variance boost patch that appreciably improves intra- and inter-frame fidelity consistency across wide range of content. Visual fidelity per bit is estimated to have increased by up to 5% with this patch, which currently isn't present in mainline SVT-AV1.
 Even though this patch should inevitably make it to mainline, the gains from having more direct control are already being realized as we can implement features like this flexibly at a pace we decide.
 Aside from that, FFmpeg has been updated to version 6.1, the SCM toggle has been replaced with a more useful Open GOP toggle, and the README has been modified to reflect some of these more recent changes with regard to SVT-AV1-PSY.
 Thank you for using Aviator, and happy encoding!
