Proxy Settings

The Project Settings Proxy dialog window

Proxy clips can be switched on and off per project. When proxies are disabled globally (see Proxy Clips), they are switched off for each new project. But if you need proxies for the new project, you can switch it on here in the Project Settings Proxy tab and change the settings for it.

备注

For illustration purposes, all check boxes have been selected. This is not the case when you open this tab.

When the Proxy clips is enabled, Kdenlive will automatically create reduced versions of your source clips and use these versions for editing. The proxy clips will be replaced with the originals for the full resolution when rendering.

The Generate for videos larger than option will automatically create proxy clips for all videos added to the project that have a frame width larger than the number of pixels specified here.

提示

You also have the choice to manually enable / disable proxy clips for each clip in your project bin by right-clicking on the clip and choosing Proxy Clip.

Specify the frame width of the proxy clip. Default is 640px which is a reasonable compromise between smooth editing performance and preview detail.

You can choose an Encoding profile for the proxy clips, which will define the size, codecs and bitrate used when creating the proxy clip. The proxy profiles can be managed from here by clicking on the Manage proxy profiles icon, or from the Settings ‣ Configure Kdenlive ‣ Proxy dialog. For more details see the Proxy Clips chapter.
