TS to SWF Converter

How to Convert TS to SWF Online

1. Upload Your TS File: Drag and drop or click "+ Add Files" to load .ts transport stream recordings from your DVR, camcorder, or HLS download. Batch upload is supported — queue several captures together and they share the same output settings.
2. Pick a Video Codec: SWF is a container, not a codec. xconvert offers FLV (Sorenson Spark / H.263 variant — the standard video codec embedded in legacy Flash) and MJPEG (Motion JPEG — each frame stored as a JPEG, simpler to decode in old authoring tools). FLV is the safer default for general playback in Ruffle and Flash-era projectors; MJPEG suits frame-accurate editing pipelines that ingest SWF.
3. Set Quality, Resolution, and Trim (Optional): Pick a Quality Preset (Lowest, Very Low, Low, Medium, High, Very High, Highest) or switch to Constant Bitrate, Constant Quality, or Specific file size for an exact MB target. Use the Preset Resolutions dropdown (720x480, 1280x720, 1920x1080, etc.) or enter custom Width x Height, and trim with a Time Range if the TS has dead air at the start.
4. Convert and Download: Click "Convert." Files are processed in your session and the resulting .swf is ready to download — no sign-up, no watermark, no email gate.

Why Convert TS to SWF?

Transport Stream (.ts) is the container the broadcast industry uses for over-the-air, cable, and HLS streaming — fixed 188-byte packets, multiplexed H.264 or HEVC video with AAC or AC-3 audio, designed to survive packet loss. SWF (ShockWave Flash; "Small Web Format" is a later backronym) is the legacy Macromedia/Adobe container that paired with Flash Player from 1996 until Adobe ended support on December 31, 2020. Most active web playback has moved to HTML5, but SWF still has a real audience: archivists, retro-game preservation projects, internal LMS/CBT courseware that hasn't been ported, museum kiosks, and any pipeline that ingests SWF to repurpose Flash-era animation. Common reasons to make the conversion:

• Flash-era courseware and LMS modules — Many corporate training courses authored in Adobe Captivate, Articulate Presenter, or Lectora before 2018 wrap third-party video as SWF. Converting a .ts lecture capture to SWF lets you drop it into an existing module without re-authoring the whole course.
• Retro web archives and fan sites — Sites preserving early-2000s web video (Newgrounds-style archives, fan museums) standardize on SWF so visitors using the Ruffle emulator get consistent playback alongside the original animations.
• Legacy projector / kiosk hardware — Trade-show kiosks, in-store displays, and older interactive whiteboards built around Flash projector executables (.exe / .app wrapping SWF) still need new content in SWF to remain in service.
• Animation pipelines that ingest SWF — Some 2D animation and motion-graphics tools (Adobe Animate, Toon Boom Harmony's legacy import) accept SWF input for tracing or re-timing footage; converting a DVR .ts capture is a quick way to feed reference video into those workflows.
• Embedding video in old Flash games — Hobbyist game modders still patching ActionScript 2/3 projects sometimes need a short cutscene as SWF rather than a separate video file.
• Compact preview proxies — A heavily compressed SWF (low bitrate FLV codec) is one of the smallest single-file video containers around — useful when you need a quick proxy under a strict size cap and your target player already supports Flash.

Just need a modern playable file? Most users will be better served converting to TS to MP4, TS to MKV, or TS to MOV instead — those play natively in browsers, phones, and editors without an emulator. If you're going the other way, see SWF to MP4 or FLV to SWF for sibling routes.

Frequently Asked Questions

Will my converted SWF play in a modern browser?

Not directly. Adobe Flash Player reached end-of-life on December 31, 2020, and all major browsers (Chrome, Firefox, Edge, Safari) removed the plugin shortly after. To play a .swf today you need Ruffle — an open-source Flash emulator written in Rust that runs as a browser extension or embedded script — or a standalone Flash projector executable. Ruffle handles most ActionScript 1/2 content and a growing share of ActionScript 3 (about 90% of the language and 77% of the API as of mid-2026). For an FLV-codec SWF with no scripting, Ruffle is generally a reliable playback target.

Why is my SWF so much larger than the original TS?

Two reasons. First, MPEG-TS files coming from a DVR or HLS download usually carry H.264 or HEVC, which are roughly 5–15 years newer than FLV/Sorenson Spark and dramatically more efficient — going from H.265 to Sorenson Spark at similar perceived quality typically inflates the bitstream 3–5×. Second, if you picked MJPEG instead of FLV, every frame is encoded independently as a JPEG with no inter-frame compression, which can multiply size by 10× or more depending on motion complexity. If size matters, stay on FLV and use a Medium or Low quality preset.

Should I pick FLV or MJPEG as the SWF codec?

Pick FLV for almost everything — it's smaller, decodes faster, and is what virtually every Flash-era player expects. Pick MJPEG only if a specific downstream tool requires it (some legacy 2D-animation imports, frame-by-frame video reference workflows) or if you need to scrub frame-accurately without inter-frame artefacts. If you're not sure, FLV is the safe answer.

Can I convert HLS .ts segments (the kind that come from streaming downloads)?

Yes. Each HLS .ts segment is a valid MPEG transport stream and xconvert will convert it. If you have multiple segments and want a single SWF, you may want to concatenate or remux them first — most TS recorders save the full broadcast as a single .ts, but HLS downloaders often produce one .ts per chunk (usually 2–10 seconds each). For multi-segment HLS, joining to MP4 first via a TS-aware tool, then converting MP4 to SWF, sometimes produces cleaner output than converting each chunk individually.

Does converting to SWF preserve audio and AC-3 5.1 surround?

Audio is preserved but downmixed. SWF/FLV only supports stereo audio in codecs like MP3, ADPCM, or Nellymoser (and AAC stereo in Flash 9+ output). AC-3 5.1 surround tracks from a broadcast .ts are mixed down to stereo during conversion — fine for a Flash projector or browser playback, but not what you want if you need to keep the surround mix. If preserving 5.1 matters, convert to MKV or MP4 instead.

What's the maximum SWF file size or duration?

The SWF v10+ spec allows files up to 4 GB and frame counts well into the millions, but practical limits are tighter. Flash projectors and Ruffle handle typical clips (tens of minutes) fine, but very long files (full-length movies) can exhaust memory in some players because SWF was designed for short animations rather than feature-length video. For anything over an hour, you'll get more reliable playback by chunking the source .ts into 10–20 minute segments before converting.

Why not just keep my file as TS, or convert to MP4?

Honestly, for almost every use case in 2026, you should — TS plays in VLC, mpv, and Safari (when wrapped in HLS), and MP4 plays everywhere. Convert to SWF only when a specific downstream tool, projector, or archive actually requires SWF. If you're not sure, try TS to MP4 first and only fall back to SWF if your target environment rejects MP4.

Will conversion work for DRM-protected or encrypted TS streams?

No. If the .ts was captured from a DRM-protected source (some IPTV providers, certain HLS streams with FairPlay/Widevine), the bitstream is encrypted and no converter can re-encode it without the keys. xconvert will either reject the file or produce a corrupted SWF. Only convert TS files you have the rights to and that are stored unencrypted on disk.

Are uploaded files kept on your servers?

Files are processed within your session and removed after it ends. No account is required, there is no watermark on the output, and there are no file-count limits or hidden Pro tiers gating the SWF converter.
