Your questions about this format
How to choose between MP4, WEBM, and MKV?
MP4 is suitable for many sharing purposes; WEBM is particularly intended for web playback. MKV may be better suited for content with multiple tracks. Look at the outputs offered for your file and test the result on the player you will actually use.
Can I extract only the audio from my video?
Yes, if MP3 is listed among the outputs of your source. Add the video, choose MP3, and start the conversion. The file must contain an audio track: a silent video cannot produce a sound recording.
Why am I being offered MKV for tracks and subtitles?
Not all outputs retain the same tracks. If the engine indicates that a MKV container is required, go back to the output selection and choose MKV instead of forcing a conversion that would remove elements. This output may fall under NoLimit.
How many videos can I convert for free?
The free offer allows one video per day, within the total quota of ten files and the limit of 100 MB per file. A batch of three files does not add three video rights: the video quota remains shared. A valid NoLimit access adjusts the limits according to the displayed offer.
What is it?
MTS is the format used by digital camcorders: it's what you'll find on the memory card of a Sony, Panasonic, or Canon device in the AVCHD line.
It carries more than just video: it embeds timecode, date, and shooting settings, all organized in a strict folder structure that must not be disturbed when copying files.
History & origin
Sony and Panasonic jointly created the AVCHD standard in 2006 to succeed the DV tape, capitalizing on H.264 encoding and memory card storage.
The format relies on the MPEG transport stream, the same one used in digital television broadcasting, chosen for its robustness.
Why it is useful
Excellent high-definition quality, with shooting metadata attached to each clip.
Professional editing software supports it flawlessly.
Limits & drawbacks
Unreadable as-is by most consumer players, and rejected by video-sharing sites.
Its folder structure is fragile: pull files out of their tree, and some software can no longer reassemble them.
Practical tips
Convert your MTS files to MP4 as soon as you offload them from the camcorder: you'll get files that play everywhere, with no visible quality loss.
Always copy the entire card, folder structure included, before doing anything else: it's the only way to avoid losing data.
