Greetings.

I have just uploaded my first-ever iClone tutorial.

I have learned a lot from other people's tutorials, and I am pleased to be able to contribute for a change.

Topic:  Smooth Camera Motion

This is something I've been working on again lately.  I was able to combine things I ready knew with some recent tips by other users.  The result was a greatly simplified way of getting smooth camera motions that looked a lot better to me.

iClone - Pointy Hat Tutorial 1 - Smooth Camera Movement from justaviking on Vimeo.

If you are in a hurry, the most important and valuable section runs from 2:24 to 4:48.

Let me know what you think.  What did you like?  What would make it better?  I know it's not perfect, but I do want to get back to working on my Pinhead project.

good tips,
you might want to touch on the "smooth camera movements" checkbox
in the camera menu.:) it does help.

Ah, yes, good point.

In my experience it is more of a subtle fix.  Maybe it helps with "small jittery motions," I'm not sure, since I don't often have them.  Others have made similar comments that it might do some good, but doesn't help with the abruptness of the camera motions.

I would love to see a situation where it really helps.  If I notice one, I'll let you know.

I also did not mention about the "Auto Level Camera" option.  I didn't want to overwhelm either myself or my audience in my first tutorial  :unsure:

An excellent first tutorial. Very informative and easy to follow along. I forget to scrub back to zero all the time... very frustrating.

By Rampa - 11 Years Ago
Looks great. Better than my first tutorial!

I also end up using the "remove all animation" quite a bit. That, and the one in the camera and light panes as well.:D

Maaaaaaaaaaaaaaaaaaaaaaaaaaaaaannnnn!!!!!
Soooooooooooooooooooooooooooooooooo usefull!!!!!!!!!!!!!!! :w00t: :P :D

Thank you very much Justaviking!!

Camera mouvement is a very important feature to story telling............

Very good tutorial, examples and patient presentation

Suggestions.

Make video using one method at a time only. Newbs should always be considered. Make additional videos to show other methods this way viewers can concentrate on what you are doing one method at a time and fix in their mind.

I am not knocking anything you have done. I think most of icloners with some timeline experience can sort it out very easily.

The timeline is a dark mystery to most newbs in the beginning. The path command is even more difficult.

IMO, this is a very helpful tutorial. Please don't be offended by suggestions.

Thank you for posting it

An excellent tutorial, Viking! Definitely makes me rethink camera and motion techniques!
Well done first tut! :)
By Peter Blood - 11 Years Ago
Excellent timing Viking. :D I'm doing a fly-by of a pretty massive object and have two rather sharp corners in it. Like you I tried drawing a path but it was over-whelming at the scale I'm using. Your tute provides the perfect answer. :w00t: I can't wait to try it out. Will let you know. ;)

Thanks man

:cool: pete

To everyone...  Thanks for the feedback and support.  It was my pleasure to be able to contribute, and if a few people find it helpful then it was worthwhile.

@rampart - Your comments are good and I don't take them as negative comments at all.

I did consider making a "Part 1" and "Part 2" so the Look At Target part was separated.  But I was afraid I'd never get around to making Part 2.

In my announcement I did mention, "If you are in a hurry, the most important and valuable section runs from 2:24 to 4:48" but it was sort of buried near the end of my post, and wasn't stated in the instruction of the actual tutorial, though I did try to let people know when the main lesson ended.  (I'm not arguing with you, I'm pointing out that the communication was probably weak on my end.)

The tutorial does assume a certain knowledge of various aspects of iClone, so it's not exactly a click-by-click tutorial.  I didn't want to have it be a "Path" tutorial, but I did try to put in a few pointers along the way.  Same with the timeline.  I also left out stuff like what you can do if you turn off the Auto Level Camera feature.  Also not mentioned is what happens if you click on the "Follow Path" button.

Wow, there is still plenty of material left for future tutorials if anyone feels motivated.  (Viking nudges himself... but it won't happen soon.)

Thanks for the comments, I appreciate them.

D'oh!

I just noticed something I am missing, and that is stating up front that I'm using Paths.  In my intro narration, and on the title page, I should have said, "How to make smooth camera motion by using Paths."

I think

RELATED TOPICS:

Some little tips I learned (or re-learned) recently from others are:

  • TIMELINE... Selecting all key frames
    • Double-click on the name of a row to select all the key frames on that row.
  • TIMELINE... Track List vs. Object Related Track
    • It is embarrassing that I only now learned to understand the difference between those two buttons (in the top-left corner of the timeline)
    • I often wondered how people made the timeline show the right object so easily
    • I always used "Object Related Track" and was constantly navigating down that list of objects, and when the project started to have a lot of objects, it got really tiresome and annoying
    • (I probably first tried it a year ago when I was only had a single prop in my project, didn't see a difference, and never thought about it again.)
    • Recently someone's tutorial made a casual comment about clicking on it, and I played with it again, and suddenly the light bulb turned on.
    • Wow, I love "Object Related Track."
  • PATHS... "Pick Path" actually means "Pick a control point"
    • I knew it, at least once upon a time, but hadn't used paths lately.
    • Someone mentioned elsewhere and made it very clear, and I wanted to be sure I included that detail in my tutorial (even though it wasn't exactly a tutorial about paths).
  • PATHS... Pick a start point, pick and end point.... or pick a point in between
    • NOT IN MY TUTORIAL
    • You can pick any path Control Point at any time.  You don't have to use them in order (but you will get an abrupt motion if you reverse direction)
    • Most useful (to me) is you can pick a mid-control point at two different times, and your camera motion will pause there.
    • This is probably easier shown that explained in writing

I've been yearning to do a beginner's guide to understanding UV maps.  I'm certain I could explain it well in a way a novice could understand.  But it would require more than doing a simple screen capture in iClone.  Maybe some day...

By Tok39Larraby - 11 Years Ago
Awesome! .. I can think of half a dozen scenes I have recently worked on which could have benefited enormously from the techniques you explained.

The convert to path function... A real gem there. I spent some serious time trying to keyframe camera paths (letting ic do the tweening) and been only slightly less disappointed with the result than I was when laying down a path. Now I can set up a series of static camera positions and 'convert to path' to tune it.

Great follow-through information applying the same technique to a 'look-at' dummy.

Glad you left in the bloopers.... Nice to see we all suffer the same problems re the timeline and forgetting to goto frame 0.

I tend to share your view re the 'smooth camera movement' checkbox. - I'm never quite sure it's doing anything ???? ! ? (Mind you, I haven't exactly spent any time experimenting with it)

Can't wait for the next installment of viking secrets!

Hi justaviking
Sorry for not responding sooner. As I said in my PM to you, much appreciated. Tried the camera path with my trench scene and it is pretty good, except for one thing. The camera movement from the bottom of the trench to the second position at the top of the trench is now too fast. Is there any way of slowing this down. I've been busy building set one of the movie so haven't experimented much with the camera path.

Thanks again
Bob
By justaviking - 11 Years Ago
@CK,

THE SHORT VERSION:

Move your timeline scrubber to the time at which you want to reach the top of the trench, and then attach your camera to a corresponding Path Control Point.

THE LONGER VERSION:

Initially, the motion will be a constant speed from one end of the path to the other.

Let's say you have a 10-second camera motion, and the path is 10 "units" long.  The camera will move one unit every second.

To slow it up at the beginning, you can move your scrubber to the 3-second point.  The camera will be sitting 3 units from the starting point.

Now right-click on the camera and do "Path --> Select Path," just like you did for the start and end points, only this time pick a Control Point closer to the beginning (maybe at 1 or 1.5 units from the start).

Now it will take 3 seconds to reach that first point.

Remember, now the second section will go faster, becuase you will still traverse the entire path in 10 seconds.

BONUS:

The same method can be used to pause your camera.  If you move your timeline scrubber to the 4-second point, and attach your camera to the same control point you used at 3 seconds, your camera will "pause" for a second (from the 3-second mark to the 4-second mark).

(Technically you could even reverse direction, but it reverses "abruptly," so now you have jarring camera movements again.  But, yeah, you could follow control points in this order: 1-4-3-10.)

ONE MORE THING (MAKE THAT "TWO"):

a) You can add and delete Path Control Points.

b) After you have set an "interior" Control Point using the metod described above, you will see it appearing in the Timeline panel (for the "CAMERA") under "Path."  You can move that point back and forth, just like a Key Frame for any other animated motion.

By Rampa - 11 Years Ago
It can be very helpful to use the transition curves on the keys in the camera's "constraint" track. That way, you can reverse direction without it being abrupt.

Confirmed.  Good tip.  Thanks.

Especially with "Ease in AND out" it becomes a nice, smooth reversal of direction.

(Note:  For those new to this, to get to this...  Highlight the camera or prop, and on the Timeline control panel (F3) you will find the Path under the "Constraint" button.  It is not a Transform function.)

TAKING THIS TO ANOTHER LEVEL:

You can Attach a path to a prop.

I want to have a camera circle around a moving vehicle.

With the vehicle stationary, I will work out my camera motion.  Then I will attach the path to the car.  Now I can drive the car down the road and around a corner, and I'll have nice smooth camera motion with the car in motion.

At least the theory sounds good.

Glad to see you making tutes!:cool: Always liked your posts and advice.

This has been a very informative thread.

By Tok39Larraby - 11 Years Ago
@justaviking..

I've tried attaching a prop to a car which works fine provided the car is not travelling down a bumpy road. Attaching to an avatar can be problematic as movement from the avatar (walking, running,) can translate into rather heavy camera jitters.

In that case, I've attached a dummy to the avatar's walk/run path (in addition to the avatar) and my second path to this dummy. That smooths out my movements and I have the added bonus that I can have the dummy move down the first path at a different rate (accelerating/decelerating) in contrast to the speed the avatar traverses the path.

Its also worth using a dummy on the camera rail and parenting your camera to the dummy instead of directly to the path. You then have the added flexibility of being able to move the camera away from/close to your 'look at' target, lest you need the 'wriggle room/space.'

I've had fun attaching a 'figure 8' and a 'clover leaf' shaped paths to a avatar 'follow-dummy'
As the avatar completes a rather linear/straight line path, the camera whizzes around the 'figure 8 / clover' whilst the entire path moves with the avatar.

If you want to get even funkier, add in some zoom action by stopping the camera at various points in the camera path; adjusting the zoom and then moving to another 'location + zoom' position (on the path) and repeating. - IC will create key-frames and 'tween' them. ... Afraid it's hit or miss with the timing but the transform track and ensuring you lay down plenty of control points on the respective paths gives you some control handles to affect timing. .. Then it's just a matter of playing till you get it looking cool.


By varying the speed and number of 'loops' my camera completes - create plenty of cool shots to splice into a camera sequence.

Aha! That worked. Thanks again, justaviking. :D
By justaviking - 11 Years Ago
@CK - I'm glad it worked.  I'm looking forward to seeing your next clip.

@Larraby - Interesting tips.  Layers upon layers, eh?  Thanks.

@Doug (Dragon), Warlord, and everyone - I appreciate the kind words.  :)

I am really looking forward to making more tutorials.  It was fun.  But right now each passing day seems to find me two or three days farther behind on my Pinhead project.  I'm sure everyone can relate to that. 

By Ibis Fernandez - 11 Years Ago
Wow great tutorial. Have so much to learn with this software. I'm really enjoying these videos, thank you so much.
By peterg - 10 Years Ago
Thanks for a great tutorial, but I am missing some point somewhere as I don't get it to work.

I have added the camera movements. I have marked the camera. I have double-clicked the Transform to mark all keyframes, but I cannot "Convert Position to Path"?

Note: I am trying this in Iclone 6. And everywhere I look the convert is greyed out. Where exactly do I need to go to convert it to a path?



Sidenote: where did the smooth camera movement go in v6, can't find that either? :)

Thanks again!

@Peter,

I'm glad you enjoyed the tutorial.  I haven't tried it in iC6 yet.  Even though I've had 6 since it came out, and I've played around with it, I haven't done any real projects yet.  That's when I really learn stuff.

I'll take a look and see if I can find it.  Maybe you found a bug (or oversight) in 6.

ADDED...

Oooo, you were so close!  :pinch:

Do the double-click like you did to select all the camera's transforms, then right-click on one of the keyframes.  :)

By peterg - 10 Years Ago
Thanks Viking, (I'm from Sweden ;-)

That's what I did, but it's still greyed out. I have 9 Camera Transform keyframes (I have tried it with less too and on less complicated scenes too), all are marked and I then went over and right-clicked every single one in case it needed to be the first, last or something like that, but to no avail. For me the Convert Position to Path is always greyed out.

I also tried this on a basic prop. Moved it around to different positions, double clicked the transform to mark all the keyframes. Went over them one-by-one, still not possible to convert to path?

So neither camera nor prop. Am I missing something?

Thanks again for trying to help out, highly appreciated :)

By justaviking - 10 Years Ago
@PeterG,

I'm American, with Norwegian ancestry.

I don't know why the "Convert to Path" isn't working for you.  It sounds like you're doing everything right.

Have you applied any of the patches?  I'm running 6.0.1213.1 (Help --> About iClone 6).

Unless anyone can come up with other ideas, you might try posting in the iClone 6.1 "Issues" thread, and/or opening a case with Reallusion Support.

I'm sorry I can't think of anything better than that.

By Rampa - 10 Years Ago
Well that's odd. It's grayed out for me as well. Guess I'll fuss with it a bit. :)

Which version, exactly, are you running?  (Patches?)

By peterg - 10 Years Ago
I am using iClone 6.01.

I also tried this on 5.5 to see if it was my system, but there I have no problem converting to path.

Update: I just saw that this was covered in the iClone 6.01 Issues thread, so there seems to be more people having this problem.
