I have a scene with 2282 frames of animation. I exported it as a BVH but the hourglass in my cursor kept to its state until I finally terminated the operation. No BVH is written. Zero bytes.

Is there a frame limit in poser in making them?

Doesn't appear to be a hard limit.  I tested just now, a very simple
animation with gradually increasing frames. 

From 1000 to 1800 the time increased more or less linearly, but
2400 frames took much longer than 1800.  (About three minutes.)

As with rendering, there's probably a soft limit depending on complexity
of scene and complexity of animation.

Hello TheOwl,

Actually I have found that past a certain point that poser goes in to what I call a waiting pattern.  It is still working on saving the files however if you try to view the status in Task Manager it shows up as Not Responding.  I just did a 2,600 frame BVH animation so that I could use it with another character and it took almost 15 minutes to save.
 
Best thing to do is have a cup of coffee and relax as sometimes poser just takes time.
Hope this helps

You might also try one of PhilC's BVH helpers, which will
probably get around Poser's internal mechanisms. 

So they say...

"Patience is a virtue." LOL!

Yep. You guys are correct. Its just taking longer to save. Oh well. Have a nice day.

That's good!

Hey I know how frustrating it can be when your working on something and you go to save and it takes for ever.  I mean 15 minutes is a long time when your really into working on a project to stop and wait on a program.
 
Sorry I wish I had something better to offer you.

Best Regards

I've been working my way through some of the CMU free .bvh's and had similar delays importing. Anything over about 2mb is slow to load, get to 3mb and Poser appears to go into hybernation. Anything bigger and I swear she's waiting for a kiss from a prince with a decent set of hedge trimmers.
I opened these bvh in Wordpad to amend the hierarchy to suit the figures I intended to use and noticed that the documents ran into hundreds of pages, so I can understand how all that info may take time to load. 
My point though, is that it may be better to break your animation down into segments, then export  more user friendly chunks. (Save it as a sequence of animated poses, then export those as bvh)
It would make life easier too when it comes to rendering, as has already been mentioned Poser seems to have its own "soft" limits. I find that after rendering about 2000 frames non-stop it gets very slow and eventually locks up so I tend to work in smaller chunks and restart the programme between segments to clear buffers or whatever is clogging up the system.

There are several free programs and not so free programs that will let you split up BVH files for easier import. I like using BVH Hacker and Slat. Also there is an obscure program called Posemaker.

I use Creado's Lifeform to edit my BVH files.

Have you guys noticed when you made some poses plus walkdesigner as an animation, the walk translations is not included?

Can any of these BVH editor's fix it?

I downloaded BVH HAcker before but I have very little idea on how to use it due to the lack of tutorials. :(         Help! Help!

I usually don't use Walk Designer due to it's effect on some of the figures I use. When I do use it I usually save the walk as a pose then apply it to the figure or use puppet master to convert it over to another figure.

Hey nyguy,

I was looking at your avatar and thought that it was showing a double "the finger" sign until I realized he is actually holding hand guns lol.

owl, there's no body element keyframed in those bvhs.  if the figure moves in poser
x-z plane, ya gotta use hip trans.

p.s. my vote would be to cut it up into 3-5 sec. clips, meaning bvhs under 200 frames,
which is also helpful when other folks hafta use 'em.

I guess I have to find a work around. Anyway I always do. Thanks again.

When using Walk Designer to export to bvh if you want the body to move you have to use a walk path, that way the hip does have x,z co-ordinates. The "Walk in Place" style of walk requires you to repeat the walk cycle as many times as you need and then set keys for Body to move the "cycling" figure around. These could be saved as an animated pose but I don't think there's a way to get them into a bvh

I am going to be working on the guns for my free Lego Figures this weekend and will be changing the Avatar using one of them. I have been working on R2D2 but keep getting side tracked by other projects and testing I am doing.
