That's it: "Non-LInear Video Editing" (what KDE-NLiVE means)

Segments are not held in memory, the multimedia backend (MLT) pulls only the 
displayed frame at any moment (roughly).
If not, this is a memory leak bug: this sometimes happen under certain 
combinations of MLT version & codec library version (ffmpeg/libav).
Unfortunately the situation in Ubuntu 14.04 is such :-\ => add 
ppa:sunab/kdenlive-release or upgrade to 14.10.

No, don't alter your original media.

If your computer seems unable to provide comfortable editing, try to enable 
"proxy clips" in kdenlive configuration (reduced resolution copies are 
automatically generated).
Final render will point back to full resolution originals.

Look at userbase.kde.org/Kdenlive/Manual for any info!
