Hello Comunity & Ipi Devs,


yesterday i would start my records for my game. I rent a sports hall and do many other things to prepare it to have a perfect result.
The person i would record use a long black pullover, a dark blue trousers with white shoes...
The hall had got blue walls and a light brown ground.

Since the update v.108, i dont try out the software again... before v. 108 it runs good and my results were perfect...

Yesterday the calibration was a flop... i try out 7 Camera-Sets, with 3 and 4 cameras an all i know about the calibration...but only absolute no reasonable resluts.

Then i clean up the set and went to home... :(

the money for the hall away, a ticket for wrong parking and no results on the computer... its incredible...


What i have do wrong???

The results were only crossing arms, or flipping shoes to the body... always... and absolute incorrect movements...


I need Support!!!

Having worked with the system for a year and a half now, I can think of hundreds of things that could go wrong, but without seeing any of what you shot, it's hard to even guess what the issue is. Could you post some frames or sample video from your session?

FWIW, for me, the latest version of iPi Studio is working better than any previous version. Calibration finishes in under 10 minutes and the result is always 100% 'green', and my performances are tracking very well. In other words, the software should be working fine, so the problem is probably with the video footage. Again, it's hard to say without seeing anything.

Can you please provide more details about the problem. Your initial description is not clear. How many cameras did you use? Did you manage to get consistent calibration results?

Can you send a screenshot of the problem? Can you send me your video? (We promise we will only use it for debugging.)

Could the cameras have been out of sequence? For example, cam 1, cam 3, cam 4, cam 2, instead of cam 1, cam 2, cam 3, cam 4? Just curious.

Hi everybody,


at this moment i upload 6 parts of my last results before i went home. The other results i delete it, because i can´t use this before.
I use the rapidshare service, i hope you ve got an account.
My Webspace is to slow for 515 mb.

In this files are 1 calibration video, 1 testvideo, 1 scenefile for ipi, and the projectfile.

When it done, i add the link with the set description.

Description:

- 3 x Ps3 eyecams
- half circle

We are still trying to download all parts of your RAR file, download is slow and it will take some time.

I was able to unpack one of your videos - the video_2010-11-20_14-51-12_RAW.avi - and I believe your problems are caused by missing background.

Your video starts with actor in T-pose. This is incorrect. Video should start with a few seconds of background (no actor), then actor in T-pose, then action. Please see our tutorial videos for an example: http://www.ipisoft.com/animation/tutorial-src.zip

Here is a brief illustration:

If that's the case, you may have a chance to fix it. Look through all your video and see if you can find a moment of clean video (i.e., background only, no performer.) If this exists, you can cut it from the video and add it to the head of each action clip. If you don't have a video editor, use Virtual Dub and make sure you use Stream Copy to avoid recompressing the video.

If you can't find a clean video segment, you may still be able to assemble a clean still image from selected frames of video using Photoshop or any paint program. Make this still image a 'held' frame in your video editor and place it at the head of your action videos (before the T-Pose.)

No guarantees that this will work, but it's better than simply writing off an entire day of work.

Hope this helps.

G.

Edit: This is another reason why I keep requesting that the clean background video be made loadable as a separate clip, at least optionally. You should be able to simply load the brief background clip once and just forget it.

I think the suggestion of a separate reference background is a very good one. It wasn't entirely clear to me about the empty background and I couldn't work out why there was a persistent "ghost" image in my early captures. Although my PC was to the side of my acting space, I was still there when operating the PC and hence in the back view of a camera now and again.

radiac, if you enable the View, Pose Mismatch option, you'll see exactly why it's confused (that's the ghost person effect that I couldn't understand at first).

Also, unless i'm mistaken, your camera order is incorrect. (I'm right at the beginning of the learning curve here too but that's my understanding.)

As facing away from the actor, start with camera 1 to the right, then go anti-clockwise camera 2, then 3. Yours goes 1, 3, 2

If i'm wrong on this, someone speak up and correct me please :)

@radiac, in which case you can still salvage this shoot. I made a similar mistake a year or so ago when I shot a session in the cafe area at my work, but I was able to correct the layout of the cameras using a compositing program. To do this, I used a program called Fusion, but you can do the same with AfterEffects if that's what you have.

IMO, it would be worth the effort since it sounds like you invested a bit of money and time for this shoot.
