WebM yokhala ndi WebM siyikhudza izi - zosankha za codec ndizofunikira.
Kodi DTS yosakira imasunga WebM kuchuluka kwa satifiketi?

Mwa default yes — 48 kHz WebM audio imakhala 48 kHz DTS audio, 44.1 kHz imakhala 44.1 kHz. Ngati mukufuna kuchepetsa kusamvana kwa kugwirizana (mwachitsanzo, 96 kHz studio masters ku 44.1 kHz CD-quality DTS) mndandanda wolowetsa wa sampling-rate amachita izi ndi kusamvana kwabwino.
Kodi ndingagwiritse ntchito DTS audio kuchokera ku fayilo ya WebM?
+
Yai - chotsani fayilo ya WebM ku gawo lotsitsa ndipo tidzachita kutulutsa mofanana. Premium imalandira ogwira ntchito ambiri mofanana; pa fayilo ya 100 (kusonkhanitsa kwa nyimbo za nyimbo) iyi ndi kusiyana pakati pa masekondi a 90 ndi maola a 8.
Kodi ndi nthawi yayitali bwanji kuti mutenge DTS kuchokera ku 1-hour WebM?
+
Audio demux + transcode imayenda mwachangu kuposa kubwezeretsa kanema - nthawi zambiri 5-15% ya nthawi yoyambira. 1-hour WebM -> DTS imatha m'maola 3-9 pa standard pipeline.
