For rendering unlipped values above 1.0f one need to set both textures and gpu colorbuffers (off-screen ones at least) to fp32 format. Shaders work by default in fp but some may contain internal clipping (will try to remove that too). My test case was putting your uber EXR over timeline with simple 100 - 0 fader. Default 8bit textures fade it to dull white, 4x bigger 32f textures nicely unveal overly bright areas as fade progressed. But color picker still was saying <a href="http://1.0.in">1.0.in</a> most bright areas, so some clipping was still around with vo opengl. I just wanted to say I never tried to fade such file before, so I never saw this effect with my own eyes. Provided me with a bit of reason for continue to try and get full opengl 32f pipeline running ( I asked question on our big black russian forum, may be some real developer will answer).</div><div dir="auto"><br></div><div dir="auto">But if you stick to x11 vo you can ignore opengl patch and only try patch changing </div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

I have tried to install CinCV without success. Some time ago I tried<br>
to install CinHV but still without success. I didn't quite understand<br>
if on CinCV histogram is clipped or not.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">well, in my case not, it goes above 100, while I think our videoscope not quite designed with full hdr in mind. Will try to locate pictures of more hdr aware editors to see how it might be done ... Also, while colorpicker in CV looks much more primitive it still works with over 1.0f values, so you can use it instead/in addition to vectoroscope/videoscope plugin.</div><div dir="auto"><br></div><div dir="auto">Can you post cincv build error?

Where can I find the older versions of CinGG?<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">whhhhm. I just canned them to live dvd images of my system I was doing periodically, so they on physical dvd disks (and each image is like 2-3 Gb big). One can try to install say ubuntu 14-16 on qemu or other virtual machine and then compile cingg history git snapshot there ...</div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
