Free and unlimited use:

Enjoy free and unlimited FLV to M2TS conversions with our service. Use it anytime, anywhere, for as many conversions as you need, without any restrictions.

Fully Local Conversion:

We deeply understand the importance of video privacy. Hence, we offer a fully local conversion service, eliminating the need to upload your videos to our servers. Experience enhanced security and privacy while converting FLV to M2TS directly on your device. Our specialized local conversion process ensures your videos are never uploaded to our servers, guaranteeing complete confidentiality. This feature is especially ideal for handling sensitive or personal files, as it ensures your data remains exclusively in your hands. Convert your videos with confidence and peace of mind, anytime.

Balancing Size and Quality:

In the realm of video conversion, one of the key challenges is finding the perfect balance between file size and video quality. This balance is crucial because it directly affects both the usability of the file (in terms of storage and sharing) and the viewing experience. A high-quality video might be ideal for professional presentations or broadcasting, but it can be too large for quick sharing or limited storage scenarios. Conversely, a smaller file is easier to share and store but might lack the clarity and detail needed for certain uses.

Customization Based on Usage:

Customize your FLV to M2TS conversions based on different use cases. For instance, a video intended for social media might prioritize a smaller size for easy uploading and streaming, while a film project might require the highest resolution and bitrate to ensure cinematic quality. This is where the ability to adjust various parameters like aspect ratio, resolution, frame rate, and bitrates becomes invaluable.

Instant File Size Preview Feature:

Recognizing these diverse needs, our service offers the "Instant File Size Preview" feature. As you adjust key parameters such as the aspect ratio, resolution, frame rate, video bitrate, and audio bitrate, our tool provides an immediate estimation of the resulting file size. This instant feedback allows you to make informed decisions on the spot, helping you to optimize your video for its intended purpose without the need for trial and error.

Fast conversion:

Understanding the importance of your time, our service is engineered for speed. We ensure quick and efficient conversion of your FLV files to high-quality M2TS format, significantly reducing waiting times. With our advanced technology, experience the convenience of rapid conversions, allowing you to receive your converted files in a fraction of the usual time. is accessible on any device with an internet connection. Whether on a desktop, tablet, or smartphone, you can easily convert FLV to M2TS anytime, anywhere.

Privacy Protection:

Your privacy is our priority. Your files are never stored on our servers, ensuring the security and confidentiality of your data.

Video parameters

Aspect Ratio:

Aspect Ratio refers to the width-to-height ratio of a video frame. Common aspect ratios include 16:9 (widescreen), 4:3 (standard), and 9:16. Choosing the right aspect ratio is crucial for ensuring your video displays correctly on various screens and fits the intended viewing experience.


Resolution determines the clarity and detail of a video. It is defined by the number of pixels along the width and height of a video frame. Higher resolutions (like 1080p, 2k, 4K) provide sharper and more detailed images, but also result in larger file sizes.

Frame Rate:

Frame Rate, measured in frames per second (fps), indicates how many individual frames or images are displayed each second in a video. Common frame rates include 24fps (cinematic), 30fps (standard), and 60fps (smooth motion). Higher frame rates result in smoother video playback but can increase the file size.

Video Bitrate:

Video Bitrate measures how much data is processed in a video stream per unit of time, usually in kilobits or megabits per second (kbps or Mbps). A higher bitrate allows for higher video quality and detail, but also increases the file size. Adjusting the bitrate can balance video quality with file size.

Audio Bitrate:

Audio Bitrate similarly measures the amount of audio data processed per second. Higher audio bitrates typically result in better sound quality but also larger audio file sizes. Adjusting the audio bitrate can optimize sound quality while managing overall file size.

Introduction to M2TS Format

Definition of M2TS

M2TS, short for MPEG-2 Transport Stream, is a high-definition video file format used on Blu-ray discs and in AVCHD (Advanced Video Coding High Definition). It's designed for multiplexing audio, video, and other streams, making it ideal for high-quality video recordings, such as 720p, 1080i, and 1080p formats.

High-Quality Video and Audio

M2TS is widely used in HD video cameras and Blu-ray discs for its ability to store high-definition video and audio. Its support for advanced video codecs and high-definition audio formats makes it suitable for professional-quality video recording and playback.

Compatibility with Blu-ray and HD Devices

M2TS files are compatible with Blu-ray players and various HD video players and editing software, making them a standard in high-definition video production and home entertainment.

Introduction to FLV Format

Definition of FLV

FLV, or Flash Video, is a file format used to deliver digital video content, primarily over the internet. It has been widely utilized by video-sharing platforms due to its compact size and compatibility with Adobe Flash Player. Known for quick buffering and smooth playback on limited bandwidth connections, FLV was a popular choice for online video streaming in its heyday.

Use in Online Video Streaming

FLV was extensively used for online video streaming due to its efficiency in data delivery and buffering, particularly in environments with limited bandwidth. Its popularity has waned with the decline of Flash technology.

Legacy Format for Web Video

While the use of Flash has diminished, FLV files remain relevant in certain legacy video content on the internet, supported by some web browsers through plugins.

What Happens When Converting FLV to M2TS

Conversion to a High-Definition Format

Converting FLV to M2TS involves re-encoding the video into a format suitable for high-definition playback and storage, such as on Blu-ray discs or HD video cameras. This process may enhance the video quality to match high-definition standards and adapt it to the M2TS file structure.

Potential Improvement in Video Quality

Depending on the original quality of the FLV file, the conversion to M2TS can result in improved video quality, especially if the FLV video is of lower resolution or quality.

Enhanced Usability with HD Devices

The converted video becomes more suitable for use with high-definition devices, including Blu-ray players and HD video editing software, enhancing its applicability in professional and home entertainment settings.

Considerations When Converting FLV to M2TS

Evaluating Purpose and Compatibility

Before converting to M2TS, consider the intended use of the video file. M2TS is ideal for high-definition video applications, such as Blu-ray disc authoring and HD video editing.

Understanding Quality and File Size Implications

Be aware of potential changes in file size and video quality. M2TS files, being high-definition, might be larger in size than the original FLV file, especially if the FLV file is lower in resolution or compressed.

Selecting Appropriate Conversion Software

Choose a conversion tool that effectively manages the FLV to M2TS conversion, ensuring that the video is encoded to meet high-definition standards without significant loss of quality.

Security in Conversion

For video files with sensitive content, opt for a service that ensures privacy and security. performs FLV to M2TS conversions directly on your local device, safeguarding the confidentiality and security of your files. This local conversion method prevents your data from being uploaded to external servers and protects it throughout the conversion process.
