What quality should I expect from the TS output?

Our converter preserves as much fidelity as MPEG Transport Stream allows. Where Flash Video carries information that MPEG Transport Stream cannot represent, that information is mapped to the closest equivalent (for example, color spaces, codec parameters, or metadata fields). For most everyday uses the result is indistinguishable from the source.

Does the FLV to TS conversion change my video resolution or frame rate?

No. By default we preserve the original resolution, aspect ratio, and frame rate from your FLV source. Only the container and, where required, the codec changes. If your source uses a codec that MPEG Transport Stream cannot store, the video stream is re-encoded to a compatible codec while keeping the visual properties identical.

What file size should I expect for the TS output?

The output size depends on the content and the compression characteristics of MPEG Transport Stream. In most cases the TS file will be in the same ballpark as your FLV input, with differences driven by how each format encodes data. There is no fixed ratio — the converter does not change quality settings unless you ask it to.

When should I convert FLV to TS instead of staying with FLV?

Convert when the application, device, or workflow you are targeting prefers MPEG Transport Stream over Flash Video. If your current FLV file already opens and behaves correctly everywhere you need it to, there is no benefit to converting — keep the original. The most common reasons to switch are compatibility (a tool only accepts TS), distribution (recipients expect TS), or feature requirements specific to MPEG Transport Stream.

What is the maximum FLV file size I can convert?

MegaConvert accepts FLV files up to 100 MB on the free service, which is enough for the vast majority of real-world Flash Video files. If you have a larger file (typical for high-resolution video or uncompressed audio), please contact us — we can sometimes accommodate larger uploads for legitimate use cases.

Is my FLV file safe and private when I upload it?

Yes. Your FLV file is uploaded over HTTPS, processed in an isolated job environment, and deleted from our servers within one hour. We do not read, index, store, or share the contents of your file. No account is required, so the upload is not associated with a personal identity. See our privacy policy for the full details.

Why Convert FLV to TS?

Understand when and why this conversion makes sense for your workflow.

Converting Flash Video to MPEG Transport Stream is often necessary to ensure playback compatibility across media players, operating systems, and streaming services. Video formats encode footage using different codecs, container structures, and compression techniques, each with distinct trade-offs between file size, quality, and support. From sharing videos online to preparing files for professional editing workflows, the right format makes a significant difference in how your content is experienced.

Flash Video has a known limitation: obsolete format since Adobe Flash Player reached end-of-life in 2020. In contrast, MPEG Transport Stream offers a key advantage: robust error recovery designed for unreliable transmission channels. While Flash Video is commonly used for legacy web video archives and content migration, MPEG Transport Stream is better suited for digital television broadcasting (dvb, atsc, isdb).

With MegaConvert, you can convert FLV to TS online without installing software, preserving your video content accurately within the target format's specifications.

How to Convert FLV to TS

Follow these simple steps to convert your file in seconds.

Upload your FLV video
Choose your .flv file using the file picker or drag it into the upload area. Video uploads can take a few seconds for short clips and longer for high-resolution footage; the progress bar shows upload status separately from conversion. Files up to 100 MB are supported.
Start the TS conversion
Click convert. Where the video codec is compatible with MPEG Transport Stream, the stream is repackaged without re-encoding to preserve original quality. Where re-encoding is required, we use industry-standard codec presets that balance file size against quality. Audio tracks are converted in parallel.
Wait for the video conversion to complete
Video conversions take longer than other file types because video data is much larger. A short clip might finish in 10 seconds; a 100 MB file may take a minute or two depending on whether re-encoding is required. The progress bar shows the percentage complete.
Download your .ts file
When the conversion finishes, click the download link to save the new MPEG Transport Stream file to your computer. The file is yours — no watermarks, no expiration on the file itself, and no MegaConvert account is required to download it.

Tips for Converting FLV to TS

Practical advice to get the best results from this conversion.

Why this conversion is worth doing

Flash Video has a known limitation: obsolete format since Adobe Flash Player reached end-of-life in 2020. MPEG Transport Stream addresses this with a key advantage: robust error recovery designed for unreliable transmission channels. Converting from FLV to TS 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

Flash Video is most commonly used for legacy web video archives and content migration, while MPEG Transport Stream is the standard for digital television broadcasting (dvb, atsc, isdb). If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where FLV is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.

Watch for this limitation in the TS output

MPEG Transport Stream has its own limitation worth understanding before you commit: packet overhead results in slightly larger file sizes than MP4. After the conversion completes, open the TS 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 FLV and TS Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

Flash Video

video/x-flv

FLV (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

Target Format

MPEG Transport Stream

video/mp2t

TS (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
