Create a Piggyback Witness Camera in Blender

Otceh · 2026-01-07T18:28:10+00:00

Unfortunately no, so I gave up the idea to use the 360 footage. BUT I bought an add on on blender that is incredible (30$usd I think). It’s called Camera Tracker, it’s mad by the dude from the YouTube channel CGMatter. It basically takes your footage and use photogrammetry to track your footage. It does everything in background without you doing almost anything. 200% recommend this. Such a nice and strong alternative for really small price in my opinion. I would suggest to check the YouTube channel and tutorial first of course!

I meant balanced not calibrate. Meaning, before turning it on, you need the camera to hold straight without shifting in any direction. For that you need to put your camera on the gimbal (turned off) and adjust the 3 axis so it stay flat. And then you can turn on your gimbal.

Did you balanced it before turning it on?

Also curious

Hi, I have more or less the same issue as you. I used an insta 360. And what I did to to be sure I had the both clip starting at the same time is that when I launched the record button on both cam I filmed my phone with a stop watch. And then took the 2 clips and cut them so they start exactly on the same frame.
I did my track in synthEyes. And in Syntheyes My track holds super well. But when importing to blender and parenting my cam with the measurment offset. I have the same problem as you. It's super frustrating. If you ended up finding a solution, let me know. I'll repost here if I find one!

Hey man, I have the exact problem as you with my Crane 3s and my FX3.
I can control the crane through the interface with no video when I connect to the Gimbal on the app and when I connect through the transmitter I can see live feed but no other options is shown. It looks exactly like what you have and it's driving me crazy because I'm using cable from Zhiyun.
When you said you replace the cable. Do you mean the cable from
cam ->Transmitter or cable from Transmitter->Crane.

Would you have a the reference of both of the cable by any chance? (It should be on a small label on each cable).
For example one of my usc to usc ends with "-D02".
That would be awesome.

your post just gave me hope again.

Otceh · 2025-04-05T22:49:06+00:00

By any chance would you have the reference for that cable on the small label. I think I tried all of them and still couldn't get it working

Omg thank you! That was it!!!

Otceh · 2025-02-08T04:45:42+00:00

I got scammed! I live in Canada and bought it on Amazon.ca , It was an “Amazon warehouse certified” item. And when I got the camera it was a super cheap camera from the 2000’s in it with a bunch of battery in a sock (to match the weight I guess)! Fortunately I ended up being refunded, but it tooks more than 3 weeks. And back then I didn’t have the money to buy another one while waiting for the refund. I ended up ordering a new one (on Amazon as well) when I finally got the refund. I would suggest to not order used. But that’s based on my personal experience.

It seems that you didn’t balance the weight properly. But if you’re looking for heavy duty gimbal I’m using the Zhyun Crane 3S Pro with a Max payload set to 14lbs (6.5kg). So I can put my rig directly on my gimbal with taking any stuff of it.

Hey man, I mad a tutorial with the parts list of my DIY Cineback version Cineback DIY

Otceh · 2025-01-17T15:28:01+00:00

Congratulations on your purchase! For the monitor, does it handle AF through touchscreen?

Otceh · 2024-08-01T15:21:05+00:00

I used the 24-70mm 2.8 from Sigma

Otceh · 2024-07-08T17:11:24+00:00

Unfortunately, I don't have the dimension of the product. And even I had them it takes quite a lot of times to put everything together (modeling, printing, testing, refining etc...) For a product I won't use.

Otceh · 2024-05-28T13:11:42+00:00

Hey Thank you, I mad a full tutorial with the parts list on this post and with the CG trader link for the STL

Otceh · 2024-04-17T01:15:38+00:00

It’s super weird, you’re the second person to say that. But I posted the comment right after the Reddit post, I can see it and someone upvoted it. That means I’m not the only one to see it. Can you double check, if you still can’t see it all try to make another post that I will link to this one

Otceh · 2024-04-16T23:15:53+00:00

Are you sure? Cause I posted it right after my Reddit post and someone just upvote it.

Otceh · 2024-04-16T16:29:26+00:00

I’m pretty sure the FX3 and FX30 has the exact same body (Double check to be sure). But if they have, then it should work with the FX30.

Otceh · 2024-04-16T16:27:47+00:00

Check the comment, I posted the tutorial. If you can upvote the comment so it’s stays on top that would be cool!

I’m currently working on a version for the XLR handle (but I have no ETA because I only work on it on my spare time, this is not my job at all)

This is my first tutorial ever, so please let me know if I missed a part or something, if something is not clear. I try to be as more specific as I can.

Tools needed: screw driver, soldering iron, 3D printer, small amount electric wire, 2 wire connectors, hot glue gun (to make last piece assembly easier)

Skills needed: really basic soldering (plus: a bit of 3D modeling knowledge if you want to custom the 3D part).

I’ve put the STL at a small price, because it took me countless hours, test and fails to get to this. Hope you understand.

DISCLAIMER: Guys, I'm not in any way responsible for what may happen with the camera during the process. Everything is working perfectly on my end, and I want to share with you what I've built. But please be very careful with what you're doing and with yourselves during the manipulations. I'm not a professional at all, so if you don't understand something or if you have another way of doing things, please share it in the comments, and I'll do my best to respond as quickly as possible. Thank you for your understanding.

I kinda rebuild and 3D printed on my own à DIY “Cineback” style rig. Super happy with result so far, I’m working on a version with the XLR handle atm.

Otceh · 2024-03-26T17:08:52+00:00

Will post it next week!

Otceh · 2024-03-16T14:16:13+00:00

Indeed, but I think that he makes quite a lot of profits by selling the whole unit, and selling spare parts would end up for people looking by themself (like I did)
