Environment

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

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 Wunjo 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 Wunjo checks every two weeks. Wunjo issues a warning message if the total cached data size exceeds this limit. If you need to purge the cache, use the Manage Cached Data feature.

4:

Show welcome screen at startup. If checked, Wunjo will show the welcome screen on which you can select a project. When unchecked, Wunjo will show the splash screen.

5:

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

6:

Prevent sleep when playing and rendering. If checked, Wunjo disables the system’s power management to avoid sleep mode and screen locking during playback and rendering.

7:

Tabs for the different environment settings.

MLT Environment

These settings tell Wunjo where to find the MLT executables and profile files. Only advanced users would really need to change these settings. Wunjo is basically a frontend to the MLT program. Since Wunjo version 25.08, MediaInfo is not needed anymore as Wunjo can read the timecode directly from MLT and shows these details in the clip properties. The values differ depending on your OS.
