Constant camera speed on path

I have a moving and tilting camera in 3D environment. I want to movement and tilting to different directions to be constant and smooth without 'locking' exact camera position to exact time. If I use keyframes to edit camera path, it messes up the constant speed. I could use motion path, but camera tilting still needs to be done with keyframes which messes up the constant motion. What's the best way to do this?
So basically I want to set camera path and positions, but leave timing for Motion to calculate.

Have you tried to Add Parameter Behavior > Oscillate to the Z-Rotation of the Camera from the Properties pane? (set the amplitude lower than 100° - say about 30-45°) [Right click on the Rotation > Z; select Add Parameter Behavior > Oscillate, if you don't know the shortcut; OR, to the Camera; click on Behaviors > Parameter Behavior > Oscillate, and from the Apply To: drop down, select Properties > Transform > Rotation > Z]

Lost my Camera and motion paths

Help! I saved and closed a project, and when I re-opened it later, i can't see my camera or motion paths. The paths tracked over several photographs, and while I can see the photos in perspective view, they do not show up in any 3D angles or camera views. The wireframe image of the camera, background and motion paths are just gone.
Thanks in advance...

hi,
have you tried opening up a prject from the autosave vault. they might be in there

Slow camera speed

Hi all. I am having trouble getting my camera speed to run as advertised. I am using a Basler A601f connected to a CVS-1450. I am currently trying 30fps, but it will only give me between 20 and 25 (not saving any information). Also, when I try to save a series of jpeg files using grab, the frame rate will only give me about 9fps and slow down gradually. Is my connection to the external hard drive or the drive itself getting overloaded? I'm using a FireWire 400 connection to a Maxtor 500Gb One-Touch external drive. Thanks!

Hi Ken,
It sounds like you might be acquiring your images onto a
host computer. Are you acquiring your
images in the Measurement and Automation Explorer? One thing that could be causing the delay is transferring
the images from the CVS to your computer.
Something you can try to solve this is to deploy your program (is it
LabVIEW or VBAI) onto the CVS and then connect your CVS to a monitor. Then in your program display your frame rate
onto the monitor using the RT video out vi.
As for when you are saving your
data the delay could be caused by your external hard drive. It could depend on how your program is written. If you are grabbing and saving each image the
time it takes to save to file could be slowing down your acquisition. You can verify
this by changing your program to see how long each loop is taking. I hope this helps. If you have any questions let me know.
Have a great day,
GG

Can Premiere CC Recognize In-Camera Speed Changes ('Ramps')?

I am editing a project shot in 6K with a Red Dragon. We recorded a number of shots with speed changes ('ramps') triggered at specific times IN-CAMERA during the course of the shot. Premiere CC does not seem to recognize the changes - and only plays the clips back at the slower rate. Is there a way to get these ramps back?
Also - on a more basic level, is it possible for Premiere to interpret the relative frame rate of off-speed clips in any kind of specific way? In the project media window, everything displays at the frame rate i've set for the project (23.976) regardless of the frame rate at which a clip was recorded.
Any help is appreciated.
Ryan W.

I thought the idea of a camera ramp was to keep the playback at a set rate so that the motion smoothly went to slow-mo as the camera fps increased. You can interpret the footage to any fps you want, you will get that option if you right click the footage in the project panel.

Help: Constant scalaing speed across several clips.

Senior moment again, I'm afraid.
I have a sequence containing many single talking heads to camera. These vary in length from 4 seconds to 30 seconds.
I want to pull into each clip at the same speed. Naturally, because they all vary in length, they will not all end on the same percentage scale-up - so setting the outpoint of each clip to, say, 110% will not work, as a shorter clip will move faster than a longer one..
I have applied scale keyframes so that each clip begins at 100%. I want to set the outpoint percentage so that each clip scales up at the same speed/velocity.
Without using trial and error (of which there are too many clips to realistically do this), can anyone please tell me how to go about setting the clip scale using speed/velocity as the criteria, not percentage. I cannot see how to make use of the graph to acheive this.
Thanks in advance.

Ok... as I was figuring this out, I'm thinking that maybe you're overthinking the math a little bit. There are two solutions.
First, if, as I originally understood your needs, you want to shave the same amount of time off each clip, simply take your first clip, write down the beginning time, take it to 110%, write down the ending time, and figure out how many frames you chopped off. Then simply take your other clips, write down their beginning times, shave off the same number of frames, and you'll get an ending time. Then you can either run a math macro on it in a program like Excel to figure out what the percentage would be, or right click on the clip in the timeline, go to "speed and duration" and there you can manually enter a frame value for what you want the clip to be. (NOTE: if you're doing a math macro on it in Excel, figure your frames as if you had footage that was 100fps, not 30 or 60... Excel doesn't know how to break 30 at 100, if you get my drift).
Now, as I was thinking this through, it occured to me, that you might be way overthinking this. A percentage is a measurement of the whole. So if you had subtract 10% from a clip of 10 seconds, you've got a clip at 9 seconds. However, if you've got a clip at 20 seconds and you subtract 10%, you're not subtracting 1, but 2, leaving you with 18 seconds. So the rate at which end up with your clips is the same, when working with percentages. Make sense? So you might just simply need to speed each clip up by the same rate (percentage) and you'll get what you're looking for.
Does this help, or have I missed your goal?

How can I remove noise from the paparazzi's constant camera clicks?

You know how annoying those camera clicks could be while you're trying to hear others talk!
I tried using SoundSoap (the demo version) from BIAS-Inc.com but it cuts down on the whole audio as well so some of the speech gets lost. Is there another filter that can get rid just of the camera clicks? There's WAY TOO MANY of them and it's impossible to do the keyframes thing and get rid of each one separately and even if I did, I would lose most of the audio because they're literally all over the place.
HELP ANYONE?? I would REALLY appreciate it...

There is no real solution for your shutter clicks. As you have discovered, many of the cures are worse than the disease.
It's something you will have to live with.
If there is no lip-sync speech involved you can always remove the actual audio and replace it with something else.

HT201295 Late 2009 Intel iMac Needs Frequent SMC reset - constant high speed running fan

Late 2009 Intel iMac is having reoccurring episodes of high speed fan running, especially after waking it up. The SMC reset by unplug and reboot works, but I worry that this is a serious sign and that the machine is slowly dying. Any thoughts? Works fine otherwise.

Camera speed question

I am looking for a camera that doesn't take forever to "load" once you turn it on and doesn't take forever between pictures. Is there a name for this feature so that I can look for it when buying?
Thanks

I take it you are looking for a camera that is fully functional once you turn it on and not go through a power up routine you have to wait for. I'm not sure how many point and shoot models are "instant on" (there probably are a few of them though), but all DSLR's power up in anywheres from .12 seconds to .30 seconds on ave.
To eliminate lag between shots you need to look for a camera with a high 'memory buffer'. This is how many shots a camera will take before it has to write to the card. For example my D3 (with buffer upgrade) gets around 110 shots (jpeg fine) before it has to write to the card and my D300's get around 100 before writing. This is assuming I have it on continuous and shoot 100 shots at once. I've never hit the buffer limit.
Hope that helps.

Unable to set custom speed to motion path on Camera

This is a followup question to "Controlling speed along motion paths"
(Many thanks to Mark Spencer and specialcase for the their excellent insights getting me this far =)
After experimenting with motion paths and realizing they were indeed what I was looking for, I set up my project so that the camera would follow specific paths along 2d images. Everything worked perfectly until I tried to modify the speed along which the camera travels along those paths.
In the motion path, in the speed drop down menu, I can select Constant, Ease in etc.... all the way to Custom, but they work slightly differently than I expected: while before (ie. applying motion curves to objects as opposed to the camera) I was able to getting a diagonal line in the Keyframe Editor where I could modify keyframes using bezier curves to adjust the speed, now, choosing the various speed options appears to change the "Transform.Position.X" and "Transform.Position.Y" curves directly.
When I select "Custom", "Motion path" and Custom Speed" appear in the keyframe menu above the Camera drop down, but its curve appears only as a dotted, completely horizontal line in the graphing window. The "Transform.Position.X" and "Transform.Position.Y" curves also revert to horizontal dotted lines. If I try to add curves to the custom speed line, the X and Y curves remain horizontal and the camera does not move.
Is there some reason I cannot get custom speeds for cameras without losing my motion path data?
Is there some way to work around this?
Thanks again for all of your help,
Tim

I'm not sure if there is some setting I have wrong:
When I try this, while I am able to set keyframes, the motion path data is reset. (ie. the Transform X and Transform Y curves reset to 0).
In the Keyframe Editor, I can make new curves for the X and Y values and for Timing, but the camera does not follow the motion path, it follows the new x and y curves. Trying to get those curves to match the motion path exactly is a large hassle.
This might help:
If I apply the motion path to an shape rather than to the camera, everything works perfectly (the object moves along the motion path, and I am able to set keyframes for the Custom Speed curve with no problems whatsoever). If I then copy the motion path directly from the shape and paste it to the camera layer, the path appears as a red curve (as it should), but the camera does not move.
Is there some way I can upload the motion file so that you can see what exactly is going on?
Thanks again,
Tim

Custom speed not working in motion path behaviour of emitter

I am trying ot make a custom speed motion path along an open spline. Any amount of adjusting of keyframes and percentages produce no movement at all along the path. The emitter is stuck at the beginning of the path. All the other speed options work except for custom, in the motion path behaviour. What's going on here?

What's going on is a little complex.
When you first add a Motion Path and select Custom Speed, you get a "default" 0% - 100% over the life of the behavior [basically the same as Constant]. If you try to add keyframes in between, it can mess things up pretty good. The results you get can be unexpected.
If you "clear" the automatic default keyframing, then the Custom speed stays at 0% (there are no keyframes). If you move the playhead and change the Custom parameter, nothing "takes" since no original keyframe is set.
In order to make a Custom Speed on a path, you need to first, clear the default keyframing (on the right edge of the column, click on the disclosure triangle and select Reset Parameter). Then, set the position you want your object to start at and Set a keyframe. Then you can advance the playhead and move the Custom Speed control to position the object on the path.

Firewire camera disappear after reboot

Hello all,
I've the following system configuration:
- 4 AVT guppy 033B firewire cameras (speed: 200 Mbps; Shutter: 250; trigger: mode0)
- Adlink SBC 852
- 1GB Ram
- CPU DUAL CORE E2200 socket 77
- firewire cable: 10 m
- firewire board: PCI dual ohci 1.1 IEEE-1394
- Windows SP2
Sequence of events:
1 - Fresh windows XP home edition installation
2 - Computer drivers
3 - Firewire cameras installation
4 - Our application installation
5 - testing. check if it's all ok
6 - Power off and wait some minutes
7 - turn on and test again
This steps where made in one day - all ok ..... In the next day:
8 - Turn on the system and check. And fine check of the system results.
9 - At 12:00 all seems to be ok and for delivering the system i decided to do one more test, rebooting the system.
10 - Error - cameras doesn't appear on MAX and had a controller exclamation mark on the device manager.
Solution:
11 - Update controller on device manager
12 - Open max and select again Imaqdx driver on the 4 cameras
So... I've a situation that after reboot may cause the cameras to disappear!
Any ideas?

Hello Jorge,
I suggest
you to re-install or Update to NI-IMAQ for IEEE 1394 Cameras Version 1.5.2 or
Later. If you are using NI-IMAQ for 1394 Cameras version 1.5.1 or
earlier, you may need to install a patch to update the NI-IMAQ for IEEE 1394
Cameras driver to version 1.5.3.

solved the problem, try to update Windows XP to Service Pack 3 and upgrade to
the Manufactuer's Latest 1394 Driver.

Exporting or saving AE motion paths

Hello all,
A slightly odd request, and I have a feeling it's not going to be possible, but... is there a way to export or save motion paths out of AE? Just like bringing vectors in from Illustrator, but in reverse.
I have a very large comp which I'm moving a camera around. I'd like to take the camera's motion path into illustrator or photoshop and create artwork based on the shape, so that when I bring it back in and add it to the comp it fits the camera's movement perfectly. I know I should probably have doe it the right way round to start with, but the cmera move is/was based on too many variables to lock it down at that stage in the project.
Any help/suggestions greatly appreciated.
Thanks.

Copy&Paste works both ways... Motion paths can be pasted as masks and even as paths in PS and AI. Just make sure to set your clipboard options in AI to AICB, not PDF...

Using Adobe After Effects CS5- Trouble with Echo & 3D Camera

Hi
i'm using Effects CS5 to a create a set of superman esque titles implementing the method found in the link below
www://vimeo.com/6562241
Everything goes smootlhy until i try making additional changes to the animation.
Here's my problem, since this process requires echo to achieve the effect. I try and set an independant camera motion from the text as it extrudes outward. But...once the text begins its animation and the camera starts to move the echo or the extrusion is ALWAYS...ALWAYS altered by the camera. (The path of the echo is follows the path of the camera.) Whether it's in a x, y, or z path it still occurs.
Sure i can change the camera angle and view it from a different perspective stationary, but i can't get them to move independant paths from each other without thecho being altered as well.
IF ANYONE OUT THERE IS A WIZ AT ADOBE AFTER EFFECTS PLEASE PLEASE RESPOND

Pre-compose the layer, then move the camera. Won't give you correct perspective, though. After all, Echo is simply a 2D buffer accumulation, not a 3D extrusion.

Giving a specific path to the reading from excel application

Hello, i want to know there is a way of giving a specific path to an application (reading from excel sheet) without all the time getting to enter the path? if someone could help. i'm using labview 8.0
Regards,
Tchaou

you could just use a path constant. Drop a path constant on the BD and right click on it and select browse and then find the file you want.

Speeds slow in the evening consistently

Hi everyone.
I had infinity 2 installed last week. Speeds at times are great - even yesterday I saw downloads exceeding 74Mbps around midnight.
However I am consistently seeing speeds slow to under 30Mbps or even slower in the evenings, which obviously coincides with peak times.
I am connected to the Wrexham exchange WNWX. The engineer did also test my line last week and he was getting about 71 Mbps without any errors. This was about midday.
I have been checking with the PC connected directly to the home hub4 via ethernet cable.
Surely the problem must be due to congestion on the cabinet/exchange/network?

Just joined here to say I am having exactly the same issue. I had BT Infinity 1 installed on June 17th and from the very beginning have been getting download speeds of up to 39mpbs except between the hours of 5pm to 11pm when I can barely achieve 1 mbp at times. It can vary by half an hour but its every single day. I too have constant upload speeds of around 8mpbs during this period.
Having read other similar threads I have neither the time or the inclination to go through the hassle of reporting this problem. However as it is obviously not my line or equipment at fault I just wanted to put my issue out there so BT could look at what appears to be a congestion issue. I live in Rochdale nr Manchester.
I know speed reduces at peak times but getting less than 1 mpb for up to 6 hours a day isn't really good enough is it. I got faster on my old Orange broadband which cost less.
