Hello everybody.

I'm currently editing AVCHD footage in a not-so-new computer. In order to do it smoother, I transcode every clip with ffmpeg to a low resolution, high quantizer MPEG-2 video that I use while editing and I change the .kdenlive file later so it uses the high quality .MTS files while rendering.

I think it could be useful to associate multiple versions of a video to a Kdenlive project's clip: a low quality one for editing purposes (only when the user needs it, of course) and a high quality one for rendering.

Thank you for your attention.

Yes, proxy clips is very much desired.
