How to Convert TS to FLV
Follow these simple steps to convert your file in seconds.
Choose a TS file
Select or drop one file up to 100 MB. Its extension must match this converter. Availability is checked before transfer.
Convert to FLV
Video is re-encoded using the selected output’s defaults. Image quality, audio and metadata can change. Check playback and duration in the application where you will use it.

Uploaded and converted files are removed automatically by regular cleanup. Files may become unavailable sooner when the service restarts.
Tips for Converting TS to FLV
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
MPEG Transport Stream has a known limitation: packet overhead results in slightly larger file sizes than MP4. Flash Video addresses this with a key advantage: compact file sizes with acceptable streaming quality. Converting from TS to FLV is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
MPEG Transport Stream is most commonly used for digital television broadcasting (dvb, atsc, isdb), while Flash Video is the standard for legacy web video archives and content migration. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where TS is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the FLV output
Flash Video has its own limitation worth understanding before you commit: obsolete format since Adobe Flash Player reached end-of-life in 2020. After the conversion completes, open the FLV file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Avoid transcoding unless necessary
Every time you transcode (re-encode) a video, some quality is lost unless you use a lossless codec. If you only need to change the container format without changing the codec, use a remux (stream copy) operation instead of a full re-encode. This preserves original quality and is much faster.
Understanding TS and FLV Formats
Learn about the source and target file formats to understand what happens during conversion.
Source Format
MPEG Transport Stream
video/mp2tTS (MPEG Transport Stream) is a container format designed for broadcasting and streaming MPEG video over unreliable or lossy media. It divides content into small fixed-size packets (188 bytes) with error correction capabilities, allowing decoders to resynchronize after transmission errors. TS is the standard container for digital television broadcasting, Blu-ray discs, and HTTP Live Streaming (HLS).
Advantages
- Robust error recovery designed for unreliable transmission channels
- Standard format for digital TV broadcasting and Blu-ray discs
- Supports live streaming with HTTP Live Streaming (HLS) protocol
Limitations
- Packet overhead results in slightly larger file sizes than MP4
- Not ideal for local file storage where error resilience is unnecessary
- Less convenient for editing compared to MP4 or MKV containers
Common Uses
- Digital television broadcasting (DVB, ATSC, ISDB)
- HTTP Live Streaming (HLS) video segments
- Blu-ray disc video storage
Target Format
Flash Video
video/x-flvFLV (Flash Video) is a container format that was used to deliver video content over the internet via Adobe Flash Player. It typically contains video encoded with Sorenson Spark or VP6 codecs and audio in MP3 or AAC format. FLV was once the dominant web video format but became obsolete after major browsers discontinued Flash Player support in 2020.
Advantages
- Compact file sizes with acceptable streaming quality
- Simple container structure that is quick to parse
- Large existing archive of legacy web video content
Limitations
- Obsolete format since Adobe Flash Player reached end-of-life in 2020
- No modern browser supports FLV playback without third-party tools
- Limited codec support compared to modern containers like MP4
Common Uses
- Legacy web video archives and content migration
- Converting old Flash-based video content to modern formats
- Historical video content from early streaming platforms
