All of them is a very suitable👌

​@matchmovemachine thank-you! Just out of interest were these drone shots from this prodject? Do you know what drones and cameras/lenes were used?? I'd love to know more about it

The great thing about compositing is that in the end it is just pixel movement and changing their color components =) therefore good compositing artist can solve any task even if he does not have proper pipeline. But how many extra time does he take for that? That is why we recommend to do all the things properly. You can pump rubber boat by your mouth but is there any reasons to do that if you can use a pump? ;)

@@matchmovemachine Thank you for your quick response!🙏 I totally get what you mean here, as even I think that it is not the correct way to do any UD plates without overscan values because I see what happens when distortion is reintroduced while compositing with live action plates. Thanks a ton!🙏🙏

Indeed, depth of field (DoF) is merely a construct, and even with a substantial DoF, the sharpest point will be located in the center. Therefore, it is crucial to determine the maximum grid blurring level before it becomes unresolvable in matchmove software. We will provide examples for reference in the near future. Ideally, moving the camera/grid for each focus distance mark would be the most efficient scenario, assuming no time constraints. However, practical considerations often introduce variables that deviate from this ideal scenario. Therefore, we recommend that the camera be fixed, the DoF be maximized, and as many focus distances as possible be captured without moving the camera. This approach is the most expedient.

Most of the vintage lenses has its own unique "character" due to manufacturing technology, so yes - in most cases they are more complex to work with them. They also provide a more complex distortion profile called "mustache" - we talked about in our Linkedin post - www.linkedin.com/feed/update/urn:li:activity:7273139584773820417/?actorCompanyId=90428950

Yes, the CameraTracker node can also generate Undistort, but we recommend using distortion grids for greater precision. Regarding the before/after comparison: The primary principle is that the camera should be solved based on undistorted data. Some software enables you to perform 2D tracking and undistortion concurrently (e.g., 3DEqualizer). You can perform 2D tracking and then undistort or vice versa (2D features will automatically adjust to the undistorted frame). Generally, we recommend performing undistortion first and then 2D tracking, as this avoids the need for redundant work in the event that your software does not support a parallel 2D tracking and undistortion workflow.

You can use geometry and project points onto it to set the orientation of the scene. Even just a card on the floor or wall can help. You can also set coordinates for 2d points, this will also set the scene. And you can also in 3d view just rotate or move the scene. And the last option is to set the scene in another program. 3dequalizer is a convenient and functional software that allows you to perform tasks in different ways, as well as to solve complex problems.

@@matchmovemachine my main software in VFX is 3dequalizer and recently I tried to use syntheyes , my main problem in 3dequalizer is constraints and I cant adjust the orientation if u have a tutorial on that it will be great

Because focus distance changing affects on lens distortion.

Good question! If both of the cameras have the same lens mount then, in theory, 1 is enough. But we will be grateful if you test that theory and send results to us to: solveme@matchmovemachine.com You just need to put 2nd camera at the same place (make sure, that sensor is on the same place compared to 1st camera) and shoot grid in Open Gate mode.

Generally no - it can be a slightly unparallel to the camera sensor. But trying to make a Grid perfectly parallel to the camera sensor is a kind of "sharing love and passion" act to the person who will work with this material. Because if you see perfectly fits grid you can not make your own part of the job bad =) For alignment we use laser leveler to set horizon + center line; laser meter to set exact height; phone/laser meter leveler to make sure that camera angle is 0. If we have a lot of lenses and whole day - we use dolly also.

@@matchmovemachine makes sense! Thank you.

The most flexible and good resulting software is 3DEqualizer, PFTrack and SynthEyes. For this shot we also used proxy geometry - it helps to get a better tracking.

@@matchmovemachine oh, "proxy geometry" this is the first time I hear about it. I'm gonna take some researches with this keyword, thanks so much for replying me!

Yes, we are planning to share some tips and tricks soon. Stay subscribed to get updates

Yes, we don't need to move camera if grid is in focus at different focus distance values - it is very handy, that is why we recommend to close aperture to max value. About anamorphic lens rotation - the industry standard camera and lenses works together very well and it is hard to mount lens badly =)

VFX report

It depends. Our regular clients trying to provide proxy geo because they know how it helps to speed it up the whole process. Sometimes we do proxy on our side

Thankyou for replying my comment.. Okay.. But how do you create the proxy environtment.? Actually i have problem create a proxy, spesially i d'know how to create that just from the footage..

@@Ferdimultimedia when you get camera you can create proxy using Nuke's ModelBuilder node, PFTrack has the same function, also it is possible in 3DEq or you can use Maya or any other 3d software

Internal studio library

@@matchmovemachine ага, вот только пополнилась ваша библиотека машинкой, не прочитав внимательно лицензию на скетчфабе...) Будем что-то решать?

3DEqualizer, PFTtrack, SynthEyes, Nuke, Maya, GeoTracker

do you have a course or a tutorial ?@@matchmovemachine

We have our inhouse knowledge database. You can find a great tutorials on 3DEqualizer website also!@@momenkhaled99
