2. I tested video rendering with a 24 seconds 1080p30 yuvj420 file wuth<br>
two channel audio. Loaded as new project. I used the default HD<br>
rendering, and put a radial blur on the video track, without changing<br>
its parameters.<br>
Rendering went OK, but slow: 4 seconds per frame. Not quite ready for<br>
prime time :-) The result played fine in Deb11/aarch64, Fedora35/x86_64<br>
and Mint 19.2/x86_64 , no visible difference from the original.</blockquote><div><br></div><div>at least it was not minutes per frame :-) </div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I have macOS in user mode, it runs fine (but need to re-install). It<br>
also ran fine in system mode (since deleted). I have not checked if<br>
there is a speed difference between the two nodes, nothing very<br>
noticable anyway.</blockquote><div><br></div><div>I think your terminology on system/user modes a bit different from assumed by qemu? </div><div><br></div><div>Can you try to explain what you mean by those two modes in your own words/experience? </div><div><br></div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I will dig into this proot, maybe it is simpler than a --target option<br>
for all ./configure scripts.<br>

Almost all documentation I find about qemu/libvirt is outdated in some<br>
respects. Execution of a non-native target just like a native one is<br>
not so important I think, as long as the build of CinGG goes alright.<br>
<br>
I prefer each VM as a separate window.<br>
