The Problem

Some video downloaders save videos as .ts files instead of normal .mp4 files. Those files can lag in VLC, behave badly in other popular media players, and feel even worse after moving them to a phone.

Converting them with VLC or heavy paid converter tools can be slow, confusing, and unnecessary when you only need a clean playable MP4.

The Fix

TS Video Converter GUI is a lightweight Windows app that converts .ts videos into .mp4 files using fast ffmpeg stream copy.

That means it usually does not re-encode the whole video. It simply remuxes the existing video and audio into an MP4 container, so conversion can finish very quickly while keeping the original quality.

Why Not VLC?

VLC can convert TS files, but:

• settings can be confusing
• conversion is often slower
• accidental re-encoding can reduce quality
• batch workflows are inconvenient

TS Video Converter GUI focuses on one thing:

fast TS to MP4 conversion with minimal setup.

Features

Feature	What It Means

Output folder picker	Save converted files wherever you want
Random unique names	Prevents accidental overwriting

Common Use Cases

• IPTV recordings

• Camera TS footage
• VLC playback issues
• Mobile playback compatibility

Example Performance

Example result on a normal Windows laptop:

File	Conversion Time	Quality Loss	CPU Usage
2.1 GB TS file	~18 seconds	none	minimal

Actual speed depends on your drive, file size, and the streams inside the TS file.

Download

Download the latest Windows zip from the Releases page:

Download TSVideoConverterGUI-Windows.zip

After downloading:

1. Extract the zip file
2. Run TSVideoConverterGUI.exe
3. Select your .ts files
4. Choose an output folder
5. Click Convert

Your converted videos will be saved with names like:

video_a8f31c92bd.mp4

How It Works

Behind the scenes, the app runs ffmpeg like this:

ffmpeg -i input.ts -c copy -map 0 output.mp4

This copies the existing streams into an MP4 file without re-encoding whenever possible.

Built With

• Python
• Tkinter
• FFmpeg
• PyInstaller

Notes

Some TS files may contain codecs or streams that are not fully compatible with MP4 containers. In those cases, re-encoding may be required.

This app is designed for fast remuxing first. If your file needs full codec conversion, use an ffmpeg re-encode command or a converter that supports re-encoding.

For Developers

Run from source:

python app.py

When running from source, you need Python and ffmpeg installed on your machine.

Build The Windows App

Put ffmpeg.exe here:

vendor/ffmpeg.exe

Install build tools:

python -m pip install -r requirements-dev.txt

Build:

powershell -ExecutionPolicy Bypass -File scripts/build-windows.ps1

The final app will be created here:

dist/TSVideoConverterGUI.exe
