DivX — compressed video
Use the format DIVX
A concrete example

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?
DivX refers to a video codec that, in everyday usage, became shorthand for a movie compressed to fit on a single CD. It could shrink an entire DVD down to a tenth of its original size, with quality most people considered acceptable.
The file itself is almost always an AVI: DivX is what's inside, not the wrapper.
History & origin
It started as a hack: in 1999, a developer modified a Microsoft MPEG-4 codec to strip out its restrictions and released it under the name DivX ;-), the winking smiley built right into the name.
A company later took over the name to turn it into a legitimate product, while the open-source community answered back with Xvid. Together, the two codecs powered the entire film-sharing era of the 2000s.
Why it is useful
Remarkable compression for its time, paired with broad compatibility across the living-room DVD players of the era, many of which proudly displayed the DivX logo.
It's still readable by most modern media players.
Limits & drawbacks
Technically outdated: H.264 does a far better job at a smaller file size.
Legacy files often suffer from poor quality and audio sync issues.
Practical tips
Convert your old DivX files to MP4: they'll play again on phones, tablets, and modern TVs.
Don't expect the picture to improve: whatever was lost in the original compression is gone for good. Conversion restores compatibility, not quality.
