Thanks, Andrew. I remember a post by Phyllis where she indicated that "scaling equation" only works for playback on the timeline and only for X11, not OpenGL. Anyway I tried to use it (X11 and OpenGL), as well as RGBA-FLOAT, 8 and 10bit, increase bit rate, etc. But nothing works. Scaling always leads to bad results.
I have a QHD screen, if I use OBS or SimpleScreenRecorder and tell them to go out with FullHD, the results are not good, everything is blurred. But they're not as bad as the resize inside of CinGG. I'm sure I'm wrong, because I'm ignoring something that's fundamental.
Also, two more things: try to check YUV Color Space in settings/peferences/appearance .. It was set to BT.601 for me, but I switched it for BT.709 for prores encoding testing ... Also, mplayer with vdpau (and xv?) output converts things slightly differently ...

I only used 'auto scale' plugin, on 1080p h264 file, while setting project size to 720p/rgba float/lanczos scaling .. of course it is blurred .... But not sure if it supposed to be *that* blurry. https://yadi.sk/i/uHnAhq2WNzox_w - prores encode, 170 Mb for 30 seconds .... Source file for this one (I cut 30 sec starting from 1 min 03 sec, up to 1 m 33 sec, roughly): https://yadi.sk/i/DGYzIbF_HdLDBA
