WMV to TS Converter

How to Convert WMV to TS Online

1. Upload Your WMV File: Click "Choose Files" or drag and drop one or more.wmv videos. Batch conversion is supported, so an entire folder of Windows Media clips can queue at once.
2. Pick a Quality Preset or Bitrate Mode: Under "File Compression" the default is the "Quality Preset" dropdown set to "Very High (Recommended)" — the other steps are Highest, High, Medium, Low, Lowest. For broadcast or HLS workflows that target a specific bitrate, switch to "Constant Bitrate" (default 4 Mbps), "Variable Bitrate" (target 4 Mbps, min 2, max 8), or "Specific file size" (default 24 MB) to hit a hard cap.
3. Set Resolution (Optional): Leave "Video resolution" on "Keep original," pick a "Preset Resolution" between 144p and 4320p, scale by "Resolution Percentage," or enter exact "Width x Height" pixels. Width-only and height-only inputs preserve the source aspect ratio.
4. Trim and Convert: Use the "Trim" control ("Unchanged" by default, or "Time Range" with HH:MM:SS.sss start and duration) to cut a segment, then click "Convert" and download the.ts file. 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 WMV to TS?

WMV (Windows Media Video) is Microsoft's container — introduced with WMV 7 in 1999 and standardized as VC-1 (SMPTE 421M) in 2006 — and it pairs almost exclusively with WMA audio. MPEG-TS (MPEG-2 Transport Stream, ISO/IEC 13818-1, originally published in 1995) is the broadcast-grade container that DVB, ATSC, and IPTV systems were built around, and it is still the original segment format for Apple HTTP Live Streaming. Re-wrapping a WMV master into TS swaps a Windows-only container for one that broadcast encoders, IPTV head-ends, and HLS packagers can ingest natively, with H.264 video and AAC audio replacing VC-1/WMA on the way through.

• HLS streaming origin masters — HLS, introduced by Apple in 2009, originally chunks H.264 + AAC content into 188-byte-packetized.ts segments referenced from an.m3u8 playlist. Most CDN packagers, Wowza, Nimble Streamer, and FFmpeg's hls muxer still default to MPEG-TS segments for broad device compatibility.
• IPTV and set-top boxes — DVB-S/C/T receivers, Enigma2 boxes, and TVHeadend record and play back.ts natively. WMV files won't load on most of this hardware without conversion.
• Broadcast ingest — Playout servers and station automation systems (Grass Valley, Imagine Communications, BroadStream) commonly accept MPEG-TS as a delivery container. WMV is rarely on the supported list.
• Error-resilient delivery — TS was specifically designed for "less reliable transmission" (terrestrial / satellite / IP). Each 188-byte packet is self-synchronizing, so a player can recover from dropped or corrupted packets — useful for live IPTV and unreliable links.
• Concatenation without remuxing — Two TS files with matching codecs can be joined with a simple file copy (cat a.ts b.ts > out.ts). This makes TS the practical intermediate when stitching ad breaks, station IDs, or chaptered captures.
• Archiving legacy Windows footage — WMV authored in the Windows Movie Maker / Expression Encoder era is awkward to import into modern NLEs. Converting to TS (or WMV to MP4 for editing) gets the footage onto a current toolchain.

WMV vs TS — Format Comparison

Bitrate Guide for HLS / Broadcast Output

The "Quality Preset" defaults are tuned for general-purpose conversion. If the TS file is a delivery target rather than a master, set "Constant Bitrate" or "Variable Bitrate" to match the renditions a streaming spec expects. Apple's HLS authoring spec, for example, recommends discrete ladders for SDR H.264 video.

Frequently Asked Questions

Will my converted TS file play in VLC and FFmpeg-based players?

Yes. VLC, MPV, and any FFmpeg-based player handle H.264 + AAC inside MPEG-TS without external codecs. Browsers and QuickTime do not play raw.ts files directly — for those, an HLS playlist (.m3u8) wrapping the segments is needed, or convert to TS to MP4 for browser playback.

Why is my.ts file slightly larger than the source WMV?

TS adds about 4% container overhead because it pads every payload into 188-byte packets and repeats Program Specific Information (PAT/PMT) tables periodically. Ittiam's analysis of MPEG2-TS encapsulation in HLS measured TS overhead at roughly 3.5–5% versus fragmented MP4 for the same audio/video. Pick a slightly lower bitrate if the source file size matters, or use "Specific file size" to cap the output.

Can I use the output directly as an HLS segment, or do I still need to segment it?

The output is a single.ts file. To produce an HLS playlist you still need a packager that splits the file into 2–10-second segments and writes the.m3u8 manifest (FFmpeg's -f hls, Bento4, Shaka Packager, or a CDN-side packager). The xconvert output is the encoded source that you feed into that packager.

Should I keep the original WMV resolution or downscale before converting?

Match the resolution to the highest rendition you'll deliver. WMV from 2003–2010-era Windows Media Encoder is often 720×480 or 854×480; upscaling to 1080p before encoding to H.264 wastes bitrate without adding detail. The "Resolution Percentage" or "Preset Resolution" controls let you stay at native resolution or downscale cleanly.

Does converting WMV to TS lose quality?

Yes — WMV/VC-1 video is decoded to pixels and re-encoded with H.264. There is no remux path because the codecs differ. To minimize generation loss, pick "Very High" quality preset or set Variable Bitrate with a target equal to or higher than the source bitrate (Windows Movie Maker WMV at 1080p averages around 6–8 Mbps, so 8 Mbps target / 12 Mbps max is safe).

What audio codec does the TS output use?

The converter outputs AAC audio inside the MPEG-TS container, which is the codec HLS authoring guidelines call for and which every modern set-top box, IPTV decoder, and HLS player supports. The source WMA track from your WMV is decoded and re-encoded, so audio also goes through one generation.

Is there a file size limit?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. Multi-gigabyte files are supported; the practical limit is upload size and connection speed. For a single 4K hour-long WMV (often 8–15 GB), trimming with the "Time Range" control first reduces both upload time and encode time.

Can I batch-convert a folder of WMV files at once?

Yes. Drop multiple.wmv files into the upload area and each one converts to its own.ts file with the same settings applied. Results download individually or as a ZIP. For per-file fine-tuning (different bitrates per clip), run them in separate batches.

Why pick TS over MP4 for streaming?

TS is the historical default for HLS and the only segment container DVB / ATSC equipment understands. MP4 (specifically fragmented MP4 / CMAF) became an HLS option only after Apple's 2016 announcement and is preferred when the same segments serve both HLS and MPEG-DASH. If your CDN or player target is a legacy HLS deployment, older Smart TVs, or any broadcast workflow, TS is the safer pick. For modern web-only delivery, MP4 / CMAF is more efficient.
