editbopContainers are not codecs
MP4, MOV, MKV and TS are containers. H.264 is a video codec with broad playback support. Copying a compatible codec avoids video re-encoding; changing the container alone does not guarantee compatibility.

A FEW SIMPLE STEPS
How to use the video converter
- 01
Open an MP4, MOV, MKV or WebM file.
- 02
Choose MP4, MOV, MKV or TS, then keep the original codec or select H.264.
- 03
Export with quality-focused settings.
Deliberately limited
Inputs are MP4, MOV, MKV and WebM; outputs are MP4, MOV, MKV or TS. It selects only the primary video and audio tracks. Extra tracks, subtitles and source metadata are not preserved.
Why can a converted video still fail to play?
A container such as MP4 is different from its codec. Keeping the original codec is faster, but your player must support it. Choose H.264 when compatibility matters; encoding takes longer and may change quality.
