How do I convert FLV to MTS online step by step?

Open LetsConvert, upload your FLV video, set MTS as target format. Optionally, enable re-encode for 1080p/4K. Press Convert, then download the MTS file. The converter remuxes H.264 streams to AVCHD container.

Why convert FLV to MTS instead of using the original file?

FLV is optimized for web playback but is not natively recognized by NLEs like Premiere Pro; MTS (AVCHD) is a camcorder format supported by editing suites and Blu-ray. Conversion also normalizes GOP and audio codec for compliant timelines.

How does FLV to MTS conversion preserve video quality and technical attributes?

The converter keeps the original H.264/AVC video stream (resolution, frame rate, bitrate) and only remuxes it into the MTS container. Audio is transcoded from AAC to AC-3 at 48kHz. IDR interval is adjusted for AVCHD, and non-standard metadata is stripped.
