Kdenlive supports transparently working with so-called proxy clips in the timeline to speed up editing and previewing. Proxies are reduced in image size and quality as compared to their original clips. But how does the proxy concept work behind the scenes?

Inside Kdenlive Projects: Bin Clips
From the perspective of MLT, Kdenlive's bin clips are nothing more producers. However, there is more to Kdenlive's bin clips than MLT thinks...
Inside Kdenlive Projects: Project Bin
MLT is the engine inside of Kdenlive. Kdenlive projects are basically MLT service networks with additional information from Kdenlive. So how gets Kdenlive's project bin gets encoded, including the hierarchy of bin folders?

Inside Kdenlive Projects: The Analyzer
Out of (sheer) curiosity I started developing a Kdenlive project analyzer as a pet project. A nice side effect of snooping around inside the XML of Kdenlive projects turned up bugs concerning the automatic audio mixing and automatic compositing of video. So what's this analyzer thing...?

Kdenlive: Adding Meta Data and Cover Art to Rendered Files
In a previous blog post I wrote about rendering MP4 video including meta data in Kdenlive. This is very convenient, as you keep the meta data (such as title, author, copyright) in the best place: in your Kdenlive project. Unfortunately, the underlying ffmpeg handles only some, but not all (usable) of the iTunes-compatible meta data elements. Even worse, ffmpeg cannot add cover art. Time for another attempt: a Kdenlive post-rendering script...
