<font size="2"><font face="trebuchet ms,sans-serif">Hehe ^^ Sounds much clearer when you say it :)</font></font><div><font size="2"><font face="trebuchet ms,sans-serif">In my experience (and own workflow) I tend to keep the distortion as late as possible. Mainly for the reason you gave, so you don't have to re-render stuff, you are not loosing quality of going back & forth with distortion to adjust stuff. and you can keep it together by doing it all in the same places (CG, additional footages, matte painting, green screen,...) rather then doing one in a shader, the other one in comp, and another one in the image editor. Especially if the distortion comes to change along the way then your workflow becomes a nightmare. </font></font></div>
<div><font size="2"><font face="trebuchet ms,sans-serif">but still having it as a shader for a quick all-in I guess could be nice, just not a priority IMO</font></font></div><div><font size="2"><font face="trebuchet ms,sans-serif"><br>
</font></font></div><div><font size="2"><font face="trebuchet ms,sans-serif">Undistortion, should be seen as a pre-process in the matchmove workflow. with the same filter in compositor. that would be perfect, and not much trouble for dev and testing at first</font></font></div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hi all,<div>I've just start reading this new list and I could't resist in giving my feed back! :)</div><div>Hope it would be interesting :D</div>
<div>As Francois says lens distortion represents part of the language used by the Director and the DoP to tell a story.</div>
<div>Undistorted images, except some cases, are useful just for CG production purposes.</div><div>Once we comp a shot we do use lot of different footages to improve our scene and the ability to distort all the elements (not only the 3D part) will be a good plus Just think about matte painting and/or other kind of rushes and you'll get the point!</div>
<div><br></div><div>We are seeing blender becoming every day more procedural and I think to have the distortion as a camera shader or as a comp node were we can pass the data collected during the tracking solve would be a great choice (maybe in comp time will be faster to edit if we want to adjust it - without re-render) </div>
<div><br></div><div>As Ton says maybe at the moment is too early to talk about design and in fact tools to improve/edit/mask a sequence of images aren't related to the libvm.</div><div> </div><div>What is important is the definition of what is a "simple shot"</div>
<div>Camera tracking relies a lot on the experience of the artist whom, watching the clips, is able to take the (hopefully good) points and turn it into useful data.</div><div><br></div><div>There are lot of false friends in 3D tracking and a very simple tracker would require much more experience in understanding how to solve a clip :)</div>
<div><br></div><div>A tracker that isn't able to handle shot within a good range of situations isn't very useful... I'm not talking about hero shots I'm just thinking at situation like:</div><div>1. hand held shot with someone acting in front of the camera </div>
<div>2. wide environment with small parallax</div><div>3. fast moving medium shots</div><div><br></div><div>just shot that are always part of a storytelling process.</div><div><br></div><font color="#888888"><div><br></div>
