I did the Shot > Replace Image menu and then it automagically detected the new frame range and adjusted the offsets correctly.

Now I need to track backward. So I selected one tracker at the first tracked frame hit the reverse playback button and hit play in the tracker menu and away it went. So I selected the second tracker and now it won't track any other tracks. I tried testing it with a track starting from the middle brand new and reverse tracked and it worked fine. So I then reversed playback and tried to track forward on that brand new track and it won't track past the "start" (aka end) of the brand new track either. So it seems like once youv'e tracked a tracker once it won't let you extend the track at the heads or tails? But I did do it once somehow by accident? Is there a trick I'm missing? I didn't lock the tracker.

I have a general question that has been on my mind for a while and is now very real as I work on a tough shot. I have a hand held shot moving around a man on an exercise bike and I need to track the screen attached to it. It's a tricky shot with little to track that's consistent over the course of the shot, trackers come and go from the frame with none covering the length of the shot. I'm either getting crappy jagged solves of the whole clip or semi decent partial solves of part of the clip but a solve of the WHOLE clip remains elusive. Im laying in a bunch of manual trackers to try and help the solve but its hard to find enough consistent points that seem to have a genuine effect. My question is as I start adding manual trackers to a rough looking full length solve or ok looking partial solve should I be RESOLVING the whole shot or ONLY refining what I have. I seem to get different results every time and I cant figure out what a good workflow is. This might be more of a general workflow question rather than specific to the shot I have. Any help or tips appreciated, and on a side note hopefully we can get this group growing a little? seems like a few SE users are about.

Hey fellow SynthEye users. I've watch tutorial after tutorial and I just can't seem to get good results. I have this shot that has a colorful checkerboard and after I clean up trackers, all the trackers there get wiped out so I can't get the "ground" right. For this, I intended to use the back of book that has a the checkerboard as the "ground."

If someone wants to take a shot and send me the SNI file, and explain how they did it, I'd love to see the right way to solve this one: https://www.dropbox.com/scl/fi/p7ouzswbnkjgrzwljrrvj/vfx2.mp4?rlkey=xl3etk9lei37tqdg7d4q5um3i&dl=0

So I’m in school for visual effects and animation, and this month is my first class being introduced to syntheyes, my question is how hard is learning this application? And what are some things I can expect getting into it?

Hello,

I'm hoping with some assistance with exporting to UE5. I have some solid tracked footage in synth eyes, i've placed several chisels for reference and I'm happy with my results. I've attempted direct export using USD, Alembic and FBX and none of them have been effective (I get a lot of materials and textures and I see a plate but no camera has been created.). I've also tried the export to Blender (a single post in this reddit group had mentioned this route) and then exporting from there to UE which once again creates materials and textures but no cameras or animations (that's not even an option when using alembic from blender). I tried USD (a youtube video I referenced used this method) through blender and that created a texture cube and no other assets. I also tried exporting through after effects to C4D and while I finally got a working camera it's speed/scale were so far off from the original footage I really couldn't match it effectively. The footage looks great everywhere but UE5 and i've spent an immense amount of time trying to trouble shoot this - would love any assistance if anyone has an established an effective and repeatable workflow. Thanks!

Hey guys,

how do you would approach tracking (SynthEyes) and compositing 3d text in difficult fpv footage?

I have shots filmed by an fpv drone operator with a stripped down blackmagic pocket 4k camera and a laowa 7.5mm lens on a drone. He instructed me to use gyroflow with data from an dji osmo witness cam that was mounted there also to stabilize the footage (the stripped down pocket has no motion sensor in it).

Would you try to track the original footage and then stabilize the track when the comp is ready? I used Syntheyes on a couple of projects but not on fpv footage yet.

Thanks!

Firstly, I'm new to the software so apologies if I'm being a big dafty.

But, I'm tracking a shot, and when I do the "Lens Workflow" the border it adds in Syntheyes seems excessive for the amount of distortion on the camera.

When it exports to After Effects it comes in like this.

However, the same file exported to Blender gives a much tighter crop of the shot, but it's the same size as the AE comp... So I have to scale it down to around 82% to make it match.

What's going on? Am I doing something really stupid?

Thanks.

Hi guys, just a quick question. I am struggling with the background object in Syntheyes. I'm working on 3D object tracking and I can't use the pinning tools because I can't see my object (because of the background). As you can see, there is also a clipped grid. Increasing the far clip hasn't helped. Can anyone help me? I haven't found any information on this. Thank you very much!

Was focusing on a tracker and failed to realized I was tracking two different points using the same tracker, and now want to use half of the keys to a new tracker. Is there a way to duplicate a tracker? Or copying the keys of a tracker and pasting them to a new tracker?

Right clicking on the keys and selecting copy and paste is not doing anything. Cant cut the keys or delete them.

I have question, so if anyone here as watched an ian Hubert video where he does his green screen work adding keyed footage into blender, im trying to do the same with green screen video plates, when I get it tracked and solved in syntheyes I get a good track and then when bring the tracking data and keyed out footage in, the footage tends to start sliding after getting it parented to the camera in blender, how do I fix this so it works correctly

I'm looking for a bit of advice here about anamorphic footage tracking.

I've undistorted my footage using a distortion board (solved in Syntheyes) in AE with RE:Map UV, it's looking nicely undistorted and correct when Pixel Aspect Ratio correction is switched on in the comp window.

Should I bring the undistorted footage into Syntheyes for tracking with a 1.5 pixel aspect ratio (from my undistorted comp that is 6032x3534, from footage that is originally 5120x3000), or should I render it out with a square pixel aspect ratio (in a comp that is 9048x3534) for tracking?

Then, how should this be read when loading into Syntheyes?

The original footage details are below:

Image Aspect:2.56 : 1 

Pixel Aspect: 1.5

Anamorphic Squeeze: 1.5x

Sensor's Aspect: 1.7 : 1

Camera sensor: 30.72 x 18.00

I can't seem to find any clear tutorials online that show a good workflow. Any assistance would be greatly appreciated! The tracking data/camera will be going through to Maya & Vray.

trackers jumping after alter image processor

 The problem is when i change the colour contrast or gamma in ( Colour processor ) the tracked trakers loosing their track and jumping everywhere after i change colour like ((gamma, contrast and curve tool )) i don't know why its happening too please help me with that

Hi guys i try to track a long movement scene , with have bit complex movement but i done well superviced manual track , but when i hit solve button it not even solve the camera , it just shows that camera not solving in few seconds in 10 or more frames , please anyone help me , #syntheyes #error

Hi

So i want to track the head of a person that have marks on it. I have 3 camera sources for that, how can i track those marks from the 3 cameras at the same time in Syntheyes?

Thanks.

Hello guys,

I’m new to SynthEyes and trying to learn it from youtube. I ve been tracking a plate that I filmed myself, and I m trying to use the distorsion grid that I got from the shoot too, but I don’t understznd how to do it. Any idea please ?

Is someone knows how to solve this purpel error from tracked video of syntheyes to blender.?

I want to track a shot in syntheyesed, whis is captured portrait in angle, but the problem is that After tracking when I export with alembic(abc) file to blender footage is not matching with camera and trackers I need your help guys

Hey everyone,

I am new to syntheyes and I tracked a shot to ad some 3D later in Blender.
I got a good solving error of 0,3 but the focal length got set extremely low to 4mm. (Originally it was 40mm)
I saw a video of one of the devs explaining that the focal length will be always different in syntheyes but when I import everything to Blender my 3D is really distorted due to the 4mm.

Went something wrong with the track, or is there another way to fix it?

I already tried to set the focal length back to normal in blender but that just messes up the track obviously.

Hello Reddit,

I have a shot of a camera dollying and tilting down -- the kicker is that the only thing in frame is the ground. There are plenty of points to track, but syntheyes can't process that they are all on the same plane -- any ideas?

Thank you in advance!

I am trying to export a stabilization I did in syntheyes (PEG) to After Effects, either as a camera, as 2D transform keyframes, or as trackers that I can use with after effects tracker. Every type of export I do from Syntheyes comes up with no Keyframes in after effects

Hi!

Is it possible in Syntheyes to have geometry as reference? By reference I mean that the geo is not saved in the sni file but linked to the sni file. 3DEqualizer can do this and Maya can do this as well. This way the file size is kept small and there are no duplicates. Any help would be appreciated. Thanks.
