How do I convert FLV to M4V using LetsConvert?

1. Go to the FLV to M4V converter page. 2. Upload your FLV file. 3. Choose M4V as the output format and, if available, select a profile for Apple devices (H.264 + AAC). 4. Click Convert and wait for processing. 5. Download the resulting M4V file. No installation required.

Why should I convert FLV to M4V instead of keeping FLV?

FLV is a Flash-based container that is no longer widely supported by browsers or Apple devices. M4V is Apple's MPEG-4 container, compatible with iTunes, Apple TV, and iPhone. M4V also offers better metadata support and lower file sizes when using H.264/AAC, while maintaining the same video quality.

What happens to video quality, subtitles, and audio bitrate during FLV to M4V conversion?

The conversion preserves resolution, frame rate, and color depth. Video is re-encoded with H.264 at a controlled quality factor, and audio is converted to AAC up to 320 kbps to maintain fidelity. Subtitles embedded in FLV are not carried over because M4V uses different subtitle formats; use external SRT files instead.

Are my uploaded files safe and secure?
