Containers and codecs
When you convert and compress a video with Clipchamp Utilities the resulting output video container and codec will depend on the optimize and customize settings you chose.
If you choose the Web or Mobile optimize preset and:
- the MP4 format, the resulting output video will be an MP4 container using the H.264 video codec and AAC audio codec.
- a WebM format, the resulting output video will be a WebM container using VP8 video codec and OGG audio codec.
- the FLV format, the resulting output video will be an FLV container using H.264 video codec and AAC audio codec.
These have emerged as the de-facto standards on modern devices (smartphones, tablets, laptops, desktops, gaming consoles, Smart TVs, etc.) and on the web.
If you choose the Windows (Microsoft Office) optimize preset:
- the output video will be an ASF container, using the WMV video codec and WMA audio codec. This works on all operating systems including Windows, Mac OS and Linux.
Frame rate and aspect ratio
We don’t make any changes to aspect ratio or frame rate (fps) of videos during the conversion process, so the output video will have the same aspect ratio and fps as the input video (you can, however, crop your video before conversion if you would like to change the aspect ratio).
