This is PART 1 of this project Hi, I need a basic video editor that will allow me to: 1. Import any video format, images, audio (with info) - MEDIA PANEL - drag/drop - save,save as,load projects. 2. Drag/drop, copy, paste, cut, split, trim in the TIMELINE / Video+Audio Tracks Unlimited (lock and unlock video+audio tracks). Any media with unlimited tracks on the timeline. 3. Preview the timeline on REAL TIME and render a video on mp4 and other formats We prefer you use ''gStreamer Editing Services'' <<< READ THIS Should work on WIN32/64 and MAC / Black GUI 800x600 Expandable / Qt 5.5 Thanks, PART 2, will add more features (text, annotations, effects, transitions...). PREVIEW the GUI in the file attached - DO NOT CHECK THE ICONS, it is only a sample!
