this new version will be able to record full screen your output screen on screen 2

I ran a little test : you can see my pc specs below, i will be running 4 layers of DXV 1280 * 720 clips to a 1208*720 output to my second screen (a HD tv thru hdmi) with no effects on Avenue. With 4 clips running and on screen, my pc runs a about 50 fps, and if i record using the record function in Avenue, my frame rate goes down to 14/17 fps, and video recorded is choppy, around 12fps. Now when i load Fraps, the Fraps frame rate indicator goes directly to my second output and stays stable at 50 fps, and when i record, its goes down to a stable 30 fps. I have managed soo far to record 6/7 mns of 1280*720 video output from Avenue at a stable 25 fps with no problems. The compression codec used by Fraps gives out good results, and these videos can now be read by VLC.
On the other hand, Mpeg streamclip is not able to convert these files to DXV, but Adobe Media Converter works fine.
enjoy
