TS to M4V Converter

How to Convert TS to M4V Online

1. Upload Your TS File: Drag and drop your .ts transport stream into the browser or click "+ Add Files" to pick one or many. Batch is supported — multiple recordings convert with the same settings in a single run.
2. Pick Video Codec and Quality Preset: H.264 is selected by default (the M4V container is built around AVC/H.264 with AAC audio for iTunes-style playback). The Quality Preset is set to "Very High (Recommended)" — drop to "High" or "Medium" if you want smaller files, or switch the File Compression mode to Specific file size, Constant Bitrate, Variable Bitrate, or Constant Quality (CRF) for fine control.
3. Resize and Trim (Optional): Under Video resolution, pick a Preset Resolution (e.g. 1080p, 720p), scale by Resolution Percentage, or enter custom Width x Height. Use Trim → Time Range to clip a section (set start and duration) instead of converting the whole broadcast.
4. Convert and Download: Click "Convert" and download each .m4v when it finishes. Files process on our servers, then auto-delete; no sign-up, no watermark.

Why Convert TS to M4V?

A TS (MPEG Transport Stream) is the raw container broadcast equipment, DVRs, and HLS streaming segmenters use. It is built to survive packet loss — fixed 188-byte packets with timing data — which is great for over-the-air reception but awkward for everyday playback: QuickTime, the Photos app, and iTunes/Apple TV typically refuse to open .ts directly, and the file often carries broadcast quirks (multiple program streams, MPEG-2 video, AC-3 audio) that Apple players don't handle gracefully.

M4V is Apple's MP4 variant introduced with the iTunes Store in 2006. It uses the same MPEG-4 Part 14 container as MP4 but is tuned for the Apple ecosystem — H.264/AVC video plus AAC (and optionally Dolby Digital/AC-3) audio — and is the format iTunes, the TV app, QuickTime, and AirPlay treat as a first-class citizen.

• Add broadcast recordings to your Apple TV library — TVHeadend, Plex DVR, and HDHomeRun all record to .ts. Converting to M4V means episodes show up correctly in the Apple TV app's "Library" tab and on the Home Sharing list.
• iTunes / Music / TV app imports — Drag-and-drop into iTunes accepts .m4v cleanly with chapter and metadata support; .ts files are silently rejected on most builds.
• AirPlay to Apple TV — Native AirPlay mirroring of MPEG-2 transport streams stutters; an H.264 + AAC M4V plays back over AirPlay 2 at full quality from iPhone or Mac.
• iPhone / iPad camera roll compatibility — Photos.app accepts H.264/AAC MP4 and M4V via the Files app; .ts requires a third-party player like VLC or Infuse.
• Strip broadcast junk — Re-muxing through this converter drops secondary audio tracks, teletext, EIT tables, and SCTE-35 ad markers that would otherwise confuse Apple devices.
• Smaller files than the source — Most ATSC/DVB .ts recordings are MPEG-2 at 15-19 Mbps; re-encoding to H.264 at "Very High" quality typically cuts the file 40-60% with no visible loss.

Frequently Asked Questions

Will my converted M4V play in iTunes and the Apple TV app?

Yes — that's the point of the M4V container. The output uses H.264 video + AAC audio in an MPEG-4 container, which iTunes (or the macOS Music/TV app on Catalina+), the Apple TV app on tvOS, and QuickTime Player all accept natively. Drag the resulting .m4v into the TV app's "Library → Add to Library" and it appears alongside your purchased content.

What's the actual difference between an M4V file and an MP4 file?

Technically very little — both are MPEG-4 Part 14 (ISO/IEC 14496-14) containers. The .m4v extension signals to Apple software that the file is iTunes-style content (H.264 + AAC, optionally with FairPlay DRM and iTunes chapter/metadata atoms). For DRM-free files, renaming .m4v to .mp4 usually plays fine in non-Apple players; this converter outputs unprotected M4V, so the file works in VLC, MX Player, Plex, and modern Smart TVs too.

Why is my .ts file rejected by iTunes / Apple TV / QuickTime?

TS is a streaming/broadcast container — Apple's playback stack expects an ISO base media file format (MP4/M4V/MOV) with a moov atom for seeking. TS files instead use Program Allocation Tables and timing packets, and often contain MPEG-2 video or multiple program streams that Apple devices won't decode. Re-muxing to M4V with H.264 + AAC fixes both the container and the codec mismatch in one pass.

My TS recording has multiple audio tracks (e.g. English + Spanish, or 5.1 + stereo). What happens?

The converter keeps the first audio track by default and transcodes it to AAC. If your TS was recorded with AC-3 5.1 surround and you want to preserve it for an Apple TV with a sound bar, switch the Audio Codec to "AC3" — M4V is one of the few containers Apple supports that carries Dolby Digital 5.1 natively (PlayStation 3 and Apple TV both decode it). Otherwise AAC stereo gives universal compatibility.

How large will the M4V be compared to my TS source?

Typical ATSC over-the-air recordings are MPEG-2 at 15-19 Mbps; DVB-T tends to be 8-12 Mbps. Re-encoding to H.264 at the "Very High" preset usually yields a 40-60% smaller file with no visible quality loss, because H.264 is roughly twice as efficient as MPEG-2 at the same perceived quality. If you need a hard cap (Apple TV USB stick, email, etc.), switch File Compression to "Specific file size" and enter a target in MB.

Can I trim out the commercials or the leading channel-tune-in noise while converting?

Yes — the Trim option lets you set a start time and duration, so you can drop the pre-roll seconds and any trailing recording overrun. For more than a single in/out point (e.g. cutting multiple ad breaks), use the video cutter first, then run the trimmed segments through this converter.

Does this preserve closed captions or subtitle tracks from the broadcast?

Broadcast TS streams typically carry EIA-608/CEA-708 captions inline with the MPEG-2 video stream. The transcode to H.264 does not currently embed those caption tracks into the M4V container; if subtitles are critical, extract them with a tool like CCExtractor before converting, or look at alternative outputs like TS to MP4 where sidecar SRT workflows are easier.

What if I'd rather stay in MP4 or move to MOV for editing?

MP4 is the more universal output if you don't specifically need iTunes/TV-app integration — use TS to MP4. For Final Cut or iMovie editing, MOV (also H.264 + AAC) is friendlier — use TS to MOV. If you have existing M4V files that need to play on Android or Windows hardware, M4V to MP4 is the reverse trip. To shrink an existing M4V without changing the container, see Compress M4V.
