MPEG-2 to TS Converter

Convert MPEG-2 to TS Online

Turn an MPEG-2 program stream into an MPEG Transport Stream — the fixed-packet, resync-friendly format that broadcast playout, IPTV multiplexers, PVR ingest and HLS segmenting all expect. Both sides of this conversion live in the same ISO/IEC 13818 systems standard, but they are built for opposite conditions: a program stream assumes a reliable disk, a transport stream assumes a lossy wire. The output here is a plain 188-byte-packet .ts — not the 192-byte BDAV framing that Blu-ray-style .m2ts files carry — with H.264 video and AAC audio by default. 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 or made public.

How to Convert MPEG-2 to TS

1. Upload Your MPEG-2 File: Drag and drop your .mpeg2 file onto the page or click "+ Add Files" to browse. Queue as many clips as you like — they all convert with the same settings.
2. Set the Video Codec and Audio Codec: Video Codec defaults to H.264 and also lists H.265, MPEG-2, MPEG-1, MPEG-4, DivX and Xvid. Audio Codec defaults to AAC and also lists AC3, MP2, MP3, EAC3 and DTS (DCA). Choose MPEG-2 video plus MP2 or AC-3 audio if you are matching a legacy broadcast profile.
3. Choose a File Compression Mode: Quality Preset opens at "Very High (Recommended)". Switch to Constant Bitrate for a predictable multiplex rate, Specific file size to hit a byte target, or Constraint Quality to cap peak bitrate while holding a quality level. Video resolution stays on Keep original unless you change it, and Trim exports a Time Range.
4. Convert and Download: Click Convert and download the .ts. No sign-up, no watermark.

Program Stream vs Transport Stream

For ordinary viewing or sharing, a transport stream is the wrong container — browsers and phone galleries do not handle raw .ts reliably. Use MPEG-2 to MP4 for that, or TS to MP4 if you already have the transport stream.

Codec Choices for a Transport Stream

Every conversion here re-encodes; there is no stream-copy passthrough, so the codec you choose is the codec that gets produced from scratch. Some combinations are far better travelled than others:

Frequently Asked Questions

Is the video rewrapped or actually re-encoded?

Re-encoded, always. There is no stream-copy path here, so even when you set Video Codec to MPEG-2 — matching the source codec — the picture is decoded and encoded again rather than passed through untouched. That is worth knowing for two reasons: it costs a generation of quality, and it means the Quality Preset and bitrate controls genuinely apply no matter which codec you pick. If your only goal was to change the packetisation without touching the picture, this is not the tool for that.

Does the .ts output use the same framing as an .m2ts file?

No, and the distinction matters if you are feeding disc-authoring software. This page writes a plain transport stream with the standard 188-byte packets. The .m2ts extension gets BDAV framing instead — 192-byte packets, each a standard 188-byte packet with a four-byte arrival-timestamp prefix — which is what Blu-ray and AVCHD structures use. If the receiving system specifically wants BDAV timestamps, convert to MPEG-2 to M2TS rather than renaming a .ts file.

Why would I want a transport stream instead of leaving it as a program stream?

Because a transport stream is built to survive data loss. It chops each elementary stream into fixed 188-byte packets and interleaves them with regular sync bytes, so a decoder that misses data can find the next packet boundary and carry on — which is exactly what you need over the air, over IP multicast, or across segment boundaries in HLS. It can also carry several programs with independent clocks in one stream. A program stream assumes none of that goes wrong, which is fine on a DVD and unhelpful on a wire.

Can I target an exact bitrate for a broadcast or IPTV profile?

Yes. Set File Compression to Constant Bitrate and enter your target — that is usually what you want for transport-stream delivery, because a fixed rate keeps a multiplex predictable in a way variable bitrate does not. Constraint Quality is the middle ground: it holds a quality level while capping the peak with a Max bitrate, which suits adaptive-streaming ladders. Specific file size works backwards from a byte target instead, and both it and the bitrate modes offer an Auto Scale toggle that will reduce resolution if the target cannot be met at the source size.

What plays a .ts file once it is converted?

VLC, mpv, FFmpeg-based tooling, broadcast monitoring gear and most IPTV set-top boxes open transport streams directly. Web browsers and phone photo galleries generally do not — a .ts is a delivery format, not a consumer file format. If someone needs to just watch the clip, give them an MP4: MPEG-2 to MP4 from the original source, or TS to MP4 if you only have the transport stream left.

Does converting to TS change my resolution or aspect ratio?

Not unless you ask. Video resolution defaults to Keep original, so a 720×576 or 1920×1080 source keeps its frame dimensions and only the container and codec change. If you do rescale, note that the presets from 4320p to 144p set height and let width follow the source aspect, so they never distort the picture on their own. The exception is anamorphic DVD material: a widescreen disc stores 16:9 inside a 720×480 or 720×576 frame using non-square pixels, and any resize here normalises pixels to square. For those sources use Width x Height and enter the display dimensions you want.

My source is interlaced DVD or broadcast footage — is it deinterlaced?

No. Nothing in this pipeline deinterlaces, so 480i and 576i material keeps its woven fields and will comb on motion during progressive playback. For a broadcast chain that is often exactly right, since the downstream equipment expects interlaced content. For anything destined for web playback it is not, and you should deinterlace with a desktop tool before uploading.

Should I use DTS audio for a surround transport stream?

No — use AC-3. The DTS encoder available to this pipeline is experimental and unreliable, and it is the wrong tool for producing a dependable surround track. AC-3 is both well supported by broadcast equipment and the pairing ATSC standardised on, so it is the right answer for 5.1 in a transport stream. AAC handles multichannel too and is the better fit for HLS and IP delivery.

How large a file can I upload, and is the conversion private?

There is no fixed per-file quota — with a long MPEG-2 capture the practical constraint is upload size and time over your own connection. Every file is sent over an encrypted connection, processed on our servers, and deleted automatically after a few hours. Nothing is watermarked, shared or made public, and no account is required.
