Fast, secure OGV to TS conversion. No registration required.
Why this pair exists — OGV is the video profile of the OGG container, typically wrapping Theora or VP8. Ergo, the TS route. A OGV to TS conversion makes a recording portable. Video containers matter more than you might expect: players that handle TS natively sometimes stutter or flat-out reject OGV with the same codec inside. Uploading above triggers a stream-level rewrap when possible, keeping the visible quality identical to the source. A quick refresher — OGV is the video profile of the OGG container, typically wrapping Theora or VP8. By contrast, TS is the MPEG transport stream, used in broadcast and HLS streaming segments.
OGV Video
Source formatOGV (Ogg Video) is an open video format using Theora codec in an Ogg container.
MPEG Transport Stream
Target formatTS (Transport Stream) is used for broadcasting, streaming, and recording live TV.
Why convert OGV to TS
Sending OGV to someone on a non-matching operating system frequently leads to "file cannot be opened". TS avoids that by sitting in the middle of everyone's compatibility list. The repackage runs quickly and without generational loss when codecs already align.
HOW TO CONVERT
OGV → TS
Drop the video file
Select a OGV file. We read the container and stream descriptors to plan the conversion.
FFmpeg handles the repackage
When codecs align, FFmpeg rewraps the existing streams into a TS container — no quality loss, near-instant finish.
Retrieve the TS
The TS download is ready in seconds for stream-copy jobs, minutes for full transcodes.
Common Use Cases
Share across platforms
Send TS files to anyone without worrying about whether they have the right software for OGV.
Embed in documents
Drop TS output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
TS often produces smaller files than OGV for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
OGV vs TS — Strengths and limitations
What each format does best, and where it falls short.
OGV Strengths
- Patent-free codec (Theora) and container (Ogg).
- Mandatory for Wikipedia uploads — preserves public-domain video.
- Good for small educational clips.
- Open-source reference implementations.
Limitations
- Compression lags H.264 by ~40% at equal quality.
- Hardware decoders never adopted Theora.
- WebM (VP9/AV1) is the modern open-codec choice.
TS Strengths
- Designed for noisy channels — packet-level error correction.
- Multi-program: one TS can carry several TV channels.
- Native format for all digital TV broadcasts and HLS streaming.
- Streaming-first: no need to download whole file to start playing.
- 30+ years of stable, deployed infrastructure.
Limitations
- Packet overhead (~3% vs Program Stream).
- Seek index is implicit — requires scanning for random access.
- Multiple audio/subtitle selection requires parsing PMT (Program Map Tables).

Approximate file sizes for common scenarios.
OGV
- Short educational clip (1 min, 480p) 8-15 MB
- Wikipedia demo video 5-50 MB
TS

- 1 hour recorded TV (HD) 4-8 GB
- Satellite transponder capture (1 min) ~300 MB
Quality & Compatibility
Resolution, frame rate and colour space are preserved end-to-end. If the TS container does not support some OGV features (chapters, multiple subtitle tracks, DRM-protected streams), those are flattened or dropped with a warning. Hard-coded subtitles in the video frames always survive.
Tips for Best Results
- Embedded subtitle tracks convert between OGV and TS when both containers support the same subtitle codec; otherwise burn the subtitles into the video first.
- For portrait (9:16) clips, make sure the TS encoder preserves the correct display aspect ratio — some players default to 16:9 if SAR is ambiguous.
- Long recordings (over an hour) benefit from chapter metadata; TS may not preserve OGV chapters — check before relying on them.
Frequently Asked Questions
Only when it has to. If the codecs inside OGV (usually H.264 or H.265 for video, AAC for audio) are accepted by TS, we stream-copy — the bytes are repackaged into the new container with zero re-encoding and no quality loss. When the source uses a codec the target does not support, we transcode at a matching bitrate to keep the visual quality close to the original.
With stream copy, expect the job to finish in seconds to tens of seconds regardless of video length — the work is mostly rewriting the container. Transcoding is slower (roughly real-time: a ten-minute clip takes about ten minutes) because every frame must be decoded and re-encoded. The progress bar shows which mode applies.
Yes. Resolution, frame rate, colour space and bit depth are preserved by default; stream copy is literally bit-identical on these parameters. If you explicitly pick a lower bitrate or a different codec in Advanced, the output is rebuilt to those settings, but the default is always "match the source".
