Hi Everyone, I have a 4 point track. I have to use a very small part of the image for the track. The graphic on the bilinear is now small. How do I set the offsets so the graphic is the original proportional size? I remember a technique for this, (I can’t remember exactly how to do it) that involved doing the 4 point track, only saving one frame of keyframes, changing a setting to edit offsets, reloading that saved single frame track, and then reloading the entire track again in the track mode. Does this sound familiar? I don’t see an edit offsets pulldown in the Vertices tracker. Maybe there is an easier way to do this now? Thanks in advance, Andrew ---

Look up bilinear UV and vertices. Youre searching for the correspondences between a vertex and its uv coordinate ---

thank you for the direction. I did the 4 point track in the vertices tab. saved that. also deleted all but the last frame of key frames. saved that as setup\_lastframe. reloaded the original track with all the keyframes in the vertices tab. went into the uv points tab and loaded the setup\_lastframe track. exited that and the graphic is back to it’s normal size and position. great to have this documented. thanks again! ---

There are also “To UV” and “To Vertices” buttons that will speed that up for you! ---

If you hit F8 with your surface selected, you’ll get the UV view (purple mesh). Adjust that by scaling the UV verts down to scale the graphic back up. ---

I knew it, of course there are. Thanks, I’m looking into this now. ---

It also kinda sounds like you want the perspective to be correct which you can do by using ‘perspective’ instead of ‘bilinear’ in the Surface Type option. ---

Yep Similar rules apply Subtly different outcomes Subtly different capabilities Personally I’m a big fan of 3d track, object track and planar track But with a different toolset form borisfx (Syntheyes) Which is irrelevant since the initial ask was about bilinears in action ---

Since the introduction of the perspective surface type I have not touched bilinear since most of what we do requires to be perspectively correct. ---

Basically the only thing I use a bilinear for is when I need to mirror out an edge for a few pixels using the crop. ---

dont forget this tool too. Quite useful. ![IMG_1461](https://us1.discourse-cdn.com/flex020/uploads/thedepartmentofexternalservices/original/2X/4/4c4550e2a61bc9586a074b14a6d854409f686da4.jpeg)
