MOV to TS Converter

MOV to TS: When a Transport Stream Is the Right Container

A QuickTime .mov is built to be stored, scrubbed and edited; an MPEG transport stream is built to be sent. TS chops the same audio and video into fixed 188-byte packets, repeats its program tables continuously, and expects that some of those packets will be lost — which is exactly what satellite, terrestrial, IPTV and HTTP streaming pipelines need, and exactly what a local file does not. The short answer: convert to TS when the file is going into a broadcast chain, a set-top box or PVR, or an HLS packager. Stay on MOV or MP4 for anything you will edit, upload or simply hand to somebody.

MOV and TS, Side by Side

Convert to TS When…

• You are feeding a hardware encoder, PVR, capture card or set-top box that ingests transport streams and nothing else.
• You are preparing material for an HLS packager. RFC 8216 defines transport stream segments as one of HLS's media segment formats and requires each one to carry a single MPEG-2 program with a PAT and PMT — which is what a .ts written here contains: one program, a program association table on PID 0 and a program map table alongside it.
• You need the stream to survive packet loss on a lossy link rather than arrive perfectly or not at all.

Stay on MP4 or MOV when…

• You want to upload it. YouTube's own list of accepted upload formats runs .MOV, .MPEG-1, .MPEG-2, .MPEG4, .MP4, .MPG, .AVI, .WMV, .MPEGPS, .FLV, 3GPP, WebM, DNxHR, ProRes, CineForm and HEVC — .ts is not on it. Use MOV to MP4 instead.
• You need chapter markers, timecode or authoring metadata to survive; none of it exists in a transport stream.
• You are editing. Most NLEs will import a .ts, but seeking through one is slower and less exact than through an indexed file.

How to Convert MOV to TS

1. Upload Your MOV File: Drag the .mov onto the page or click "+ Add Files" to pick one or several. Each file is uploaded over an encrypted connection and converted on our servers, with the same settings applied across the batch.
2. Set the Video and Audio Codec: Video Codec is preselected to H.264 and Audio Codec to AAC — the pair HLS players and modern set-top boxes expect. Choose MPEG-2 instead when the destination is legacy broadcast gear, and AC3 or EAC3 when the receiving equipment wants a Dolby track.
3. Pick a Rate Control Mode: File Compression starts on Quality Preset at "Very High". On H.264 and H.265 you can also use Constant Quality or Constraint Quality for a real CRF target, or Constant Bitrate / Variable Bitrate when a delivery chain specifies a rate. Video resolution starts on "Keep original", and Trim takes a start time and duration if you only need part of the clip.
4. Convert and Download: Click Convert and save the .ts. No sign-up, no watermark; your upload and the finished file are both deleted from our servers automatically after a few hours.

TS or M2TS? 188 Bytes Versus 192

These two extensions are frequently treated as interchangeable and are not. A plain transport stream packet is 188 bytes and begins with the 0x47 sync byte; the BDAV variant used on Blu-ray and AVCHD prefixes each packet with a four-byte arrival timestamp, making 192-byte packets whose sync byte sits at offset 4. Our converter follows the extension you ask for, so this page writes plain 188-byte packets and MOV to M2TS writes the BDAV framing.

Frequently Asked Questions

Why convert MOV to TS instead of just using MP4?

Because the two containers are designed around opposite assumptions. MP4 and MOV assume the whole file arrives and can be indexed; TS assumes a stream that may lose packets and must keep playing anyway, which is why it repeats its program tables and uses a fixed packet size with a sync byte to lock onto. If your file is going into a broadcast, IPTV or HLS pipeline, that structure is the entire point. If it is going onto a hard drive or a website's download link, it is pure overhead.

Does converting MOV to TS lose quality?

Yes, a little, because this is a re-encode rather than a container swap — our server decodes the video and encodes it again into the transport stream; it never copies the original stream through untouched. With Video Codec left on H.264 and the Quality Preset high, the loss is generally not visible, and the output lands close in size to an equivalent H.264 MP4 plus a few percent of packet overhead. If you need a true bit-preserving remux, that is a job for a local tool such as ffmpeg with stream copy.

Which codecs should I choose for HLS segments?

H.264 video with AAC audio — the pair this page already preselects. RFC 8216 lists MPEG-2 transport streams as an HLS media segment format and requires each segment to contain a single program with a PAT and PMT; the files written here satisfy that. What this page does not do is segment the stream or write the .m3u8 playlist, so you still need a packager to slice the output into short segments and generate the manifest.

Can I play a .ts file on a normal computer or TV?

VLC, MPV and most desktop players open .ts directly, and a great many smart TVs, media boxes and PVRs treat it as a native format. Web browsers do not — there is no <video> support for raw transport streams, which is why HLS exists as a delivery layer on top. If you simply want a file that plays everywhere without explanation, convert the other direction with TS to MP4.

Will my chapters, timecode or metadata survive?

No. A transport stream carries the tables a decoder needs — program association, program map, timing and program clock references — and has no equivalent of QuickTime's chapter tracks, creation metadata or authoring tags. Anything of that kind is dropped in the conversion. Keep the original .mov or an MP4 master alongside the transport stream if that information matters.

Why is my TS file slightly larger than the MOV it came from?

Two reasons stack up. Every 188-byte packet spends four bytes on its header, and the muxer repeats the program tables at regular intervals so a receiver tuning in mid-stream can start decoding — both are the cost of being resilient to loss. On top of that, the re-encode targets your chosen quality rather than the source's exact bitrate. Lowering the Quality Preset or setting an explicit bitrate closes the gap.

Can I use MPEG-2 in a TS for older broadcast equipment?

Yes — MPEG-2 is in the Video Codec list precisely for that. Be aware that MPEG-2 has no CRF mode, so the Constant Quality and Constraint Quality sliders do nothing when it is selected and the encoder falls back to a bitrate derived from the output frame size. With MPEG-2 chosen, set the frame size and an explicit bitrate rather than reaching for a quality slider.

How large a file can I upload, and what happens to it afterwards?

The real constraint is upload size and time rather than anything on your end, so for a long recording the Trim control — a start time plus a duration, in seconds or HH:MM:SS.sss — is the quickest route to the part you actually need. Files travel over an encrypted connection, are converted on our servers, and both the upload and the result are deleted automatically after a few hours. Nothing is shared or made public, there is no sign-up, and no watermark is added.
