Intel yafalitsa kutulutsidwa kwa laibulale ya SVT-AV1 1.0 (Scalable Video Technology AV1), yomwe imapereka makina ojambulira ndi ma decoder amtundu wa AV1, womwe umagwiritsa ntchito luso la computing la hardware lomwe limapezeka mu Intel CPUs zamakono. Cholinga chachikulu cha SVT-AV1 ndikukwaniritsa mulingo wa magwiridwe antchito oyenera pamayendedwe apakanema apakanema ndikugwiritsa ntchito mautumiki a pavidiyo pakufunika (VOD). Khodiyo imapangidwa ngati gawo la polojekiti ya OpenVisualCloud, yomwe imapanganso ma encoder a SVT-HEVC ndi SVT-VP9, ndipo imagawidwa pansi pa chilolezo cha BSD.
Kuti mugwiritse ntchito SVT-AV1, mufunika purosesa ya Intel Core ya m'badwo wachisanu (Intel Xeon E5-v4 ndi ma CPU atsopano). Kuyika mitsinje ya 10-bit AV1 pamtundu wa 4K kumafuna 48 GB ya RAM, 1080p - 16 GB, 720p - 8 GB, 480p - 4 GB. Chifukwa cha zovuta za ma algorithms omwe amagwiritsidwa ntchito mu AV1, kuyika kalembedwe kameneka kumafuna zinthu zambiri kuposa mawonekedwe ena, omwe salola kugwiritsa ntchito encoder ya AV1 yosinthira nthawi yeniyeni. Mwachitsanzo, encoder ya masheya kuchokera ku projekiti ya AV1 imafuna kuwerengera nthawi 5721, 5869 ndi 658 kuyerekeza ndi ma encoder a x264 ("main"), x264 ("mkulu") ndi ma encoder a libvpx-vp9.
Zina mwa zosintha pakutulutsidwa kwatsopano kwa SVT-AV1:
- Thandizo lowonjezera la ma S-frames (Switching Frames), mafelemu apakatikati omwe zomwe zili mkati mwake zitha kuneneratu kutengera mafelemu ozindikiritsidwa kale a kanema yemweyo pazapamwamba kwambiri. Mafelemu a S amakulolani kuti muwonjezere mphamvu ya kuponderezana kwa mitsinje yamoyo.
- Added Constant Bit Rate (CBR) encoding control mode kuti muchepetse pang'ono.
- Thandizo lowonjezera potumiza zambiri za malo opangira chroma.
- Anawonjezera luso kudumpha zithunzi denoising pambuyo akhakula kaphatikizidwe.
- Thandizo loyimba mwachangu lakulitsidwa mpaka ma presets M0-M10.
- Kugwiritsa ntchito njira ya "-fast-decode" kwakhala kosavuta ndipo gawo loyamba lakusintha mwachangu lakonzedwa.
- Mawonekedwe a zotsatira za encoding awongoleredwa.
- Kugwiritsa ntchito kukumbukira kwakonzedwa bwino.
- Anawonjezera kukhathamiritsa kwina kutengera malangizo a AVX2.
