Convert WEBM to OPUS
WEBM → OPUS. Source file ≤ 2 GB · Output ≤ 100 MB · audio stream #1 → audio · video → ∅.
WebM uses VP8, VP9 or AV1 video and Opus or Vorbis audio here. Opus output uses a 48 kHz audio sampling rate. Only the first audio track is extracted; the source must contain audio. Video input is limited to 2 GB; audio output to 100 MB.
WEBM → OPUS: Example settings
60 s × 192 kbps ÷ 8 ≈ 1.44 MB • Opus / 48 kHz
OPUS: Output
Sizes are examples, not guarantees. Container overhead is extra; variable bitrate and image content change the result. Keep the original and compare the output.
