Environment

This section defines some of the most important settings for Kdenlive.

configure_environment_2412

The Environment section

1:

Concurrent threads. Defines the number of threads to use for proxy clip generation and transcode jobs. Those jobs will run in the background. The value entered is passed to ffmpeg as the -threads parameter. Increasing this parameter may not have an effect if you have changed the proxy encoding settings using project settings to a codec that ffmpeg does not do multi-threading on. Multi-threading is supported for MPEG-2, MPEG-4, H.264, and VP8.

2:

Use lower CPU priority. This instructs Kdenlive to lower the priority of the proxy clip generation and transcode jobs. It helps keeping the main UI responsive when proxies are created or clips are being transcoded.

3:

Warn if cached data exceeds. Add a maximal cache size that Kdenlive checks every two weeks. Kdenlive issues a warning message if the total cached data size exceeds this limit. If you need to purge the cache, use the 캐시된 데이터 관리 feature.

4:

Check for updates. If checked, Kdenlive will show a pop-up window with a reminder if your version is older than six (6) months.

5:

Tabs for the different environment settings.

MLT Environment

These settings tell Kdenlive where to find the MLT executables and profile files. Only advanced users would really need to change these settings. Kdenlive is basically a frontend to the MLT program. If you have MediaInfo installed and provide the path here, Kdenlive shows more details in the clip properties. The values differ depending on your OS.
