TS to OPUS Converter

How to Convert TS to OPUS Online

1. Upload Your TS File: Drag and drop or click "+ Add Files" to select MPEG-2 Transport Stream (.ts) recordings from your PVR, IPTV grab, or camcorder. Batch uploads are supported.
2. Pick Quality Preset or Bitrate: Default is Highest. Use the Quality Preset dropdown (Lowest, Very Low, Low, Medium, High, Very High, Highest) for one-click sizing, or open Custom Bitrate to set Variable Bitrate (recommended — 64-96 kbps for speech, 96-128 kbps for music, 160-192 kbps for storage) or Constant Bitrate (set values from 8 kbps up to 510 kbps).
3. Tune Audio Channel, Sample Rate, or Trim (Optional): Pick Mono or Stereo under Audio Channel, force a Sample Rate (8000, 12000, 16000, 24000, or 48000 Hz — Opus resamples everything to 48 kHz internally regardless), or use Trim with HH:MM:SS.ms to cut out commercials, dead air, or a clip.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert TS to OPUS?

TS (MPEG-2 Transport Stream) is the container TV tuners, PVRs, IPTV recorders, and some camcorders write to disk. The audio inside is usually AC-3 (Dolby Digital), AAC, or MP2 — formats designed in the 1990s for broadcast bitrates of 192-448 kbps. Opus, standardized as IETF RFC 6716 in September 2012, gets the same perceptual quality at roughly half the bitrate, so extracting the audio track to Opus lets you keep the audio (radio show, sermon, podcast feed, language lesson) without lugging around the full video.

• Archive radio and podcast recordings — A 1-hour AC-3 audio track at 192 kbps is ~86 MB; the same hour at Opus 64 kbps VBR is ~28 MB with no audible loss for speech, and ships smaller than MP3 at 96 kbps.
• Send long voice clips through messaging apps — Discord (10 MB free tier since September 2024, 500 MB on Nitro Basic+), Telegram (2 GB per file), and WhatsApp (16 MB per attachment) all accept Opus natively — it's the codec they already use for voice messages.
• Strip audio from a TV-tuner recording — When you only want the dialogue from a .ts rip from your Hauppauge / HDHomeRun / TVHeadend setup, demuxing to Opus drops file size by 80-90% versus keeping the full transport stream.
• Feed audio into web apps and WebRTC — Opus is the default codec for WebRTC voice (Zoom, Meet, Discord, Jitsi), so an Opus file is ready to drop into a browser-based player or Web Audio pipeline with no transcoding.
• Stream over slow connections — Opus stays intelligible for speech at 12-16 kbps and listenable for music at 32-48 kbps, far below the floor of MP3 (typically 96 kbps minimum for tolerable music).
• Cross-platform playback — Native support in Chrome, Firefox, Edge, Safari 11+, VLC, foobar2000, mpv, and Android since 5.0; iOS plays Opus in .caf and via apps but not natively in Safari for some legacy .opus containers, so test on Apple devices before mass-converting.

Frequently Asked Questions

Why does my Opus file sound the same at 128 kbps as my TS audio at 384 kbps?

Because Opus is roughly 2-3x more bitrate-efficient than AC-3 and AAC. Listening tests by the Xiph.Org Foundation found Opus at 128 kbps VBR is "pretty much transparent" for stereo music — meaning trained listeners cannot reliably distinguish it from the uncompressed source. The 384 kbps AC-3 in your TS file is broadcast-spec overhead, not a true quality target.

What audio codec is inside a TS file before I convert it?

It varies. US ATSC broadcasts typically use AC-3 (Dolby Digital) at 192-448 kbps. European DVB-T transports often use MP2 or HE-AAC. Newer IPTV streams and camcorder TS files (AVCHD-derived) usually carry AC-3 or LPCM. xconvert decodes whichever codec is present and re-encodes the audio to Opus.

Should I use Variable Bitrate or Constant Bitrate?

Variable Bitrate (VBR) for almost every case — it's Opus's default and lets the encoder spend bits where they're needed (complex music passages) and skip where they aren't (silence, speech gaps). Constant Bitrate (CBR) is only useful for fixed-bandwidth streaming pipelines where every packet must be the same size.

Will the conversion drop sync or lose chapters?

There are no chapters to lose — Opus is a pure audio file, not a container with sidecar metadata. The conversion extracts the primary audio track and discards video, subtitles, and Program/System Information. If your TS has multiple audio tracks (e.g., English + Spanish), only the first is extracted by default.

Can I play Opus on iPhone, Mac, or Windows without extra software?

• Windows 10 (1809+) and Windows 11 play Opus natively in Files app and Media Player.
• macOS plays Opus in QuickTime since macOS 11 Big Sur (2020).
• iOS Safari plays Opus in CAF/M4A wrappers but .opus extensions need a third-party player like VLC.
• Android has played Opus natively since version 5.0 Lollipop (2014).
• All modern browsers (Chrome, Firefox, Edge, Safari 11+) play Opus inside <audio> tags directly.

If you need to share with someone on older Apple hardware, convert to Opus → MP3 afterward as a fallback.

What sample rate should I pick when Opus only encodes at 48 kHz internally?

The Sample Rate dropdown tells the encoder which rate to declare in the output header, which downstream players use for resampling. Opus's CELT layer always operates at 48 kHz internally regardless, so for music keep 48000 Hz; for voice-only at very low bitrates 16000 or 24000 Hz can produce slightly smaller files. There's no audible benefit to forcing 8000 Hz unless you're matching legacy telephony pipelines.

Can I keep the video and just compress the TS file?

If you need the video too, don't convert — use compress TS instead to shrink the transport stream while keeping both tracks. Converting to Opus is a one-way trip that discards the video.

Why is my output file bigger than I expected?

Two common causes. (1) You picked Highest preset (which uses ~192-256 kbps VBR) for a stereo source — drop to Medium (96-128 kbps). (2) The source TS has 5.1 surround that was upmixed to stereo with all six channels still encoded — pick Mono in Audio Channel if the source is dialogue-only.

Should I convert TS to Opus or to MP3?

Opus if your target devices and browsers are modern (post-2015): half the file size of MP3 for equivalent quality, and royalty-free. MP3 only if you need to play on legacy hardware (car stereos pre-2018, old MP3 players, hardware not updated since 2010). For more options see TS to MP3, TS to AAC, or TS to FLAC for lossless.
