TS to AVI Converter

How to Convert TS to AVI Online

1. Upload Your TS File: Drag and drop or click "Add Files" to select TS (MPEG-2 Transport Stream) files. Cable-box DVR exports, IPTV captures, HDHomeRun recordings, TiVo .ts rips, satellite receiver dumps, and HLS segment grabs from youtube-dl / yt-dlp all work. Batch is supported — drop in a whole season's worth of recordings at once.
2. Pick a Video Codec and Compression Method: Default is DivX (the codec AVI was built around in the early 2000s). Pick Xvid for the open-source equivalent, MPEG-4 for the broadest legacy DVD-player support, MPEG-2 to keep the TS source codec and minimize re-encoding loss, or H.264 if your AVI player supports it. Set Quality Preset (Highest → Lowest, default Very High), target a percentage of source size, lock to a Specific File Size in MB, or fine-tune with Constant Bitrate, Variable Bitrate, Constant Quality, or Constraint Quality.
3. Resize or Trim (Optional): Pick a Preset Resolution (1080p / 720p / 480p / 360p), enter a custom Width × Height, scale by Resolution Percentage, or use Time Range trim with start time + duration in HH:MM:SS.sss to chop out commercials, the news lead-in, or the dead air at the end of a DVR capture. Audio codec defaults to MP3 — switch to AC-3 to preserve broadcast surround, AAC for size, or PCM for lossless.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no upload to a third-party server.

Why Convert TS to AVI?

TS (MPEG-2 Transport Stream) is the container broadcast TV, IPTV, ATSC over-the-air, and DVB satellite have all used since the late 1990s. It's designed to survive packet loss on noisy transmission paths, which is why every DVR, set-top box, HDHomeRun, and IPTV recorder writes .ts files. AVI (Audio Video Interleave) is Microsoft's 1992 container — older, simpler, and supported by virtually every legacy Windows tool, hardware DVD player, and offline media appliance ever shipped. Common reasons to convert TS → AVI:

• Legacy DVD-player and set-top-box playback — A lot of standalone DVD players, older Sony / LG / Philips home-theater units, and car head units accept AVI on a USB stick but choke on TS. Re-encoding to DivX / Xvid in AVI is the standard recipe for getting a recorded show onto a 2010-era player without dragging out a laptop.
• Importing into older video editors — Sony Vegas 13, Pinnacle Studio 14, Adobe Premiere CS5, Windows Movie Maker, and VirtualDub all import AVI cleanly but stumble on the MPEG-2 transport stream wrapper. AVI is the path of least resistance for a 10-year-old NLE that can't be upgraded.
• Archiving cable-box DVR exports — Recordings off a Comcast/Xfinity, DirecTV, or Spectrum DVR (when exportable) usually land as .ts. Converting to AVI gives a single self-contained file you can drop on a NAS, USB drive, or Plex library without TS's PAT/PMT/PCR overhead.
• IPTV recordings from Tvheadend, Plex DVR, NextPVR — Linux-based DVR stacks write transport streams natively. AVI is the format Windows-era media-center hardware (HTPCs, WD TV Live, Roku 1, classic Xbox) plays back without complaint.
• Splitting a multi-program TS — Over-the-air ATSC streams often pack a primary HD program plus 1-2 SD subchannels in a single 6 MHz mux. Converting to AVI flattens the recording to a single program-stream-style file, which downstream tools handle without the PID-selection dance TS demands.
• Simple hardware compatibility — Generic 4K media players, older smart TVs (Samsung 2010-2014, LG NetCast), and many car infotainment systems play AVI off USB but don't recognize .ts as a video file at all. AVI is still the lowest-common-denominator format for offline hardware. See also TS to MP4 for modern device targets and TS to MKV for lossless remuxing.

Frequently Asked Questions

Why does my TS file sometimes look like a single huge unsplittable blob?

TS streams from DVRs and IPTV captures often record multi-hour blocks (a 4-hour football game, an overnight DVR session, a back-to-back-episode marathon) as a single .ts. Re-encoding to AVI gives you a clean, splittable, indexable file. Use Time Range trim to slice out the segment you actually want — the rest of the recording is dropped during conversion.

My DVR exported a .ts that won't play in Windows Media Player. Will the AVI fix that?

Yes. Default Windows Media Player on Windows 10/11 doesn't ship with a TS demuxer or an MPEG-2 decoder. Re-encoding to AVI with DivX or Xvid produces a file WMP plays out of the box on the same machine — no codec packs, no K-Lite, no VLC required.

Should I pick DivX, Xvid, or MPEG-4?

DivX for default playback on standalone DVD players and smart TVs from 2005-2015 — the codec those devices were certified against. Xvid is the open-source twin: identical compression, slightly less hardware certification, no licensing implications. MPEG-4 ASP for the absolute widest legacy compatibility — every AVI player ever made accepts it, at a small size cost vs DivX/Xvid.

Will the AC-3 surround audio from my broadcast TS survive?

Yes — pick AC-3 as the audio codec output to keep the original Dolby Digital track bit-for-bit. Default is MP3 (smaller, universally supported), which downmixes 5.1 to stereo. For HTPC or home-theater playback off the AVI, AC-3 preserves the surround mix; for laptop / USB-stick playback in a car, MP3 stereo is usually what you want.

What about multi-program ATSC streams from an HDHomeRun or USB tuner?

ATSC over-the-air captures often contain a primary HD program plus SD subchannels (e.g., a network feed + a weather subchannel) multiplexed in one .ts. The converter selects the primary video and audio program by default and writes a single-program AVI. If you need a specific subchannel, demux the TS first with a tool like Project X or ffmpeg -map, then convert the extracted program to AVI here.

How big a TS file can I convert?

Multi-hour DVR captures (4-8 GB transport streams) work. Conversion happens in your browser session, so the practical limit is your device's available memory and patience for the upload. For very long broadcasts, trim first with Time Range to extract the part you need — converting a 30-minute slice of a 6-hour recording is dramatically faster than converting the whole thing.

Is there a quality loss converting MPEG-2 TS to DivX/Xvid AVI?

There's a small re-encoding loss any time you change codecs. At Quality Preset Very High (the default) the difference is invisible at typical viewing distances. To minimize loss, pick MPEG-2 as the AVI video codec — it keeps the source codec and only re-wraps the container, which is nearly lossless. Trade-off: MPEG-2 inside AVI is 2-3x larger than DivX/Xvid.

What's the difference between this and converting to MP4?

AVI is the legacy / hardware-compatibility target — DVD players, older Windows tools, 2010-era HTPCs. MP4 is the modern target — phones, browsers, smart TVs from 2018+, every cloud service. Pick AVI when the destination device is older than ~2015. For everything else, TS to MP4 is the better landing page.
