立即开始转换Frequently Asked Questions
Is MKV better than MP4?
MKV is more feature-rich but MP4 is more compatible. Use MKV for archiving movies; use MP4 for sharing and device compatibility.
Why can't my TV play MKV files?
Smart TVs vary widely in MKV support. Check your TV's specs, or use a media player like Roku, Fire TV, or Shield that supports MKV.
Can I convert MKV to MP4?
Yes, HandBrake and VLC can convert MKV to MP4. If the video codec is already H.264, you can often just remux without re-encoding.
How do I add subtitles to MKV?
Use MKVToolNix to add, remove, or rearrange subtitle and audio tracks in MKV files without re-encoding the video.
Is MKV safe to download?
MKV itself is safe - it is just a container. Be cautious about the source of files, not the format itself.
