Thanks for sharing that, great to see proxy generation is well on the
way and that it actually works. I completely understand the workaround
but hope there will be a way to not require both streams in the
timeline editor, this can make for a very busy project. I already
often find editing with 2 monitors that even then the timeline editor
window fills up pretty fast.

Thanks GG for working on this feature, it's really going to help keep
aging hardware productive!

 I played with this proxy mode some more, and found if I just open
file, and set 
 proxy settings to 1/2 scale, mjpeg/qt format - it all will work fine,
until I 
 try to render edited track in its full size/quality...here Cinelerra
 just created proxy file, and not main file. But this can be
workarounded by

 1) Open original file, set proxy setting, wait for proxy file
generation to 
 complete. (name of video track will be changed to _proxy variant)
 2) Open original file again, with addition strategy about putting new
file on 
 new tracks.
 3) set visibility/renderability for original file to false (green
arrow at the 
 left from track, in main window)
 4) Edit video (there is mode where edits applied to all armed
 5) Set project size back to original
 6) set visibility for proxy file to false, for original file (track)
to true.
 7) render as usual ...

 This seems to work for simple cut/paste editing.
