Constant speed motion effect

I am trying to put a 200% motion effect on a clip and I get a message that says A CONFLICT OCCURED DURING A TRIM OPERATION Anyone know why I might be getting this message?
Thanks

The usual explanation is your expanded clip interferes with other media in your timeline.
usual solutions: work in an isolated sequence and nest it back into your main sequence or work on your time alteration at the end of your sequence and then copy and paste.
You can search for the error message here on the forum and you will plenty of threads.

Ken Burns Effect - Variable vs. Constant Speed

On a test slideshow I worked on in iPhoto, I noticed that the Ken Burns effect uses a "variable" motion. Meaning if I'm utilizing the zoom effect, it'll start out slow, then speed up, then slow down again for each photo. However, I just want a constant speed zoom for each photo.
Is there away to have the Ken Burns effect zoom (and/or pan) with a constant speed?

100 brownie points to Terrabay! LOL
For those that don't know how Terrabay arrived at his solution: iMovie DOES let you dictate how long your transition (for ANY transition) is when you put it into your show. When you press editing and go into transitions drag the transition you want into your time line - you can adjust how long you want it to be and which direction you want it to go before you put it in your show, and if youve already put it in but want to lengthen/shorten it, just click on your transition in the time line, make the change and press UPDATE. Simple.

Slow motion (constant speed) rendering problem. ATTENTION PROs!

I have tried almost everything to try and fix my problem and now I am going insane!
I am editing a short promo featuring constant speed adjustments and video filters. When I render the video seems to drop frames and jutter. Why is this when i have only reduced the speed of the clips by 50% or 75% ? ?
I have put it through compressor several times and printed the video onto DVD to see if the problem lies within any other program, but i believe my problem is with final Cut HD.
The footage is HDV interlaced. I have made sure the frame blending options are checked although this makes no difference and have rendered it I dont know how many time.
Do I need to bring the original rushes out of the bin and adjust the speed again from scratch...essentially start again?
HELP! I am going mad!

I have done it!
I firstly made a quicktime movie, using current settings, to create a single HDV clip. I then created a new sequence, titled HDV, and opened up the sequence settings. Going into the video processing tab I changed field dominance to 'upper odd' and motion to 'best'. I then dropped the new HDV clip into the timeline. At this point I sent this new clip to Compressor and chose the 'best quality 90min 16/9', MPEG 2 two pass + Dolby. EXPORT....HAPPY DAYS! The results are great. Perhaps I could make it better by stopping the footage down to SD first?

Slow motion effect

I was wondering how to get that slow motion effect that is so commonly used i music videos. I have a canon xha1 that shoots 60i and 50i. To achieve this effect do I do it all in FCP, or is a combination of having the fps high and then the sequence at 24. I could do it in FCP, but it doesn't look clean. If any body has anysuggestions, thankyou. peace. E.

Final Cut Pro can do slow motion with or without frame blending. In both instances you are creating duplicates of frames in order to create a slow motion effect. These look okay in video but with the effects you are talking about are done with large production values where the shots are done with slow mags where the film is running at a high rate of speed to get more frames in an action. There are cameras today that allow you to over and under crank footage but mainly they are tapeless formats where you are recording to hard drives, disks or cards.
you might want to investigate After Effects version 7 or later where it does time warping where individual pixels are blended rather than an entire frame like in Final Cut.

Constant Speed + Timing not working

Hi,
I have two clips that are in the same group. I've created a motion path whereas the clips are pulled from left to right across the canvas. The 2 clips are a panormic still image that has been stiched in PS.
I've set the timing speed to "Constant Speed" but when I replay the clip the speed is not constant and it seems like the motion "fades" in at the start and "fades" out at the end.
Thanks in advance.

hi,
it sounds like there is an amount of easing in and out of the motion path. two things you can do, navigate to the keyframes window, select the keyframes and set the interpolation to linear. Or dont use a motion path and simply apply a Throw behaviour, or set your own keyframes.

How can slow-motion iphone6 video be exported to imovie on an iMac and retain its slow motion effect ?

how can slow-motion iphone6 video be exported to imovie on an iMac and retain its slow motion effect ?

thx, i can't see where you do that (access the function to slow the motion of a clip). in the help file it says to 'right click' on the clip to access those functions but when i do i get these optios below (no motion, pan, zoom, pan and zoom). i want access the speed/duration sliders.
i would say the function isn't available at all, but i could be looking in the wrong place (although i have tried everything).
thx for your reply.

How to properly timewarp 59.94 footage for slow motion effect for 29.97 output

I have footage filmed in 59.94 that I want to use for slow motion effects and output to 29.97. Using timewarp I seem to get duplicate frames at times. What would the best workflow to accomplish the cleanest result? I've tried interpreting the footage at 29.97 and keeping it at its native 59.94. At this point I feel like I'm just confusing myself further by just trying random things. Thanks!

Always interpret footage as what it really is. If it is really 59.94 progressive then that's what it should be interpreted as. It will play at the right speed in any comp of any frame rate. IOW, if the footage is 10 seconds and you put it in a 99fps comp and play it back at full frame rate the clip will still be 10 seconds long. If you put it in a comp that's 15 frames per second, the clip will still be 10 seconds long.
Make sure you understand that.
There is a chance, and a good chance, that your footage is actually full frame 59.94 fps video. That's why I suggested putting it in a comp that's also 59.94 fps and checking for duplicate frames.
There is also a chance that your footage is actually 29.97 fps interlaced. If you separate fields and look at the footage in a 59.94 fps comp you won't see any duplicate frames.
To change the speed of the clip you just need to apply Time Remapping, Time Warp, or any of the other Time Time tools in AE. It doesn't make any difference what the frame rate of the composition is, you'll be changing the length of the clip.
To keep from creating duplicate frames you either need software that interprets the new, extra frames or you need to use an exact whole number multiple of the frame rate for rendering.
Where did you get the footage? What Camera? What are you trying to do with it? What is the final destination (delivery) for your project.

How about using a 60fps video for a smooth slow motion effect in a 30fps project ?

Hey all,
I happen to have a video camera that is able to shoot either in 720p/60fps or 720p/30fps.
As you guessed it, 60 fps mode is very useful for action sports when you want to do some slow motion effect running very smoothly.
I have few questions I would love to be answered, and I was not able to find answers till now.
Here they are :
1/ If I want my final video file to be, let's say, 25 fps, is it mandatory that my project is 25 fps too ?
What will happen if I do a 30fps project and that I export to a 25fps file ? Does Premiere simply remove some extra frames ? Or will it lead to a longer video ? What consequence on the final result if frames are removed ? I mean, will I be able to see any difference or will the difference remain theorical ?
2/ Let's say I have both 30fps and 60fps videos. I set my project to 30fps. If I import my 60fps video to the timeline, it will be adjusted to 30fps and some frames disappear to keep the duration the same. Okay, this is clear to me.
But now, what if I import my 60fps to the timeline, but set the speed to 50% ? Will Premiere apply the 50% to the original file (therefore I should have all the frames displayed on the timeline : 60/2=30 fps), or to the 30fps-adjusted file of the timeline, leading to some jerky footage?
3/ If I want to use my 60fps for slow motion purpose in my 30fps project, would it be a good idea to right-click on this file in the project windows, going to the "modify" menu to set the image frequency to 30fps ?
Because while doing so, if I drag the file to the timeline, I noticed it would last 2 times longer (resulting in a slow motion video) Does that mean that ALL the frames of the original video are displayed ? Can someone tell me what exactly does Premiere ?
I would be very grateful if someone could tell me what are the correct settings to chose in order to realise the best slow motion videos as possible.
Thanks in advance !

With due respect... this does not answer my question and does not help me that much , but anyway, thank you for the very constructive answer ^^.
I'm not sure I would even have considered doing this by myself...
I hope I do not get this kind of answer because you feel like my question was silly or unpolite... To my mind this was a pretty serious question.
Shooternz, next time you need to go 150 km far away from where you are, go by feet rather than with a car, I'm sure you will have plenty of satisfaction too. Just cross the fingers for you not to be in a hurry while it's raining outside.
Well, I may be naive but i thought some experts already had the answer to this (I guess I'm not the only one who intend to do some slo mo), and would have been kind enough to share this knowledge with me. That's what sometimes happens in communities.
Please note I do not intend others to do the job for me, I'm just asking if someone already knows the answer.
I asked this question because I couldn't find any documentation about this, and I guess asking on internet was the next step, as testing would be like the last resort, being very time consuming.
It was easy to check the effect of dragging a file to the timeline to see if it played normally or not, but it's definitely not to count and compare each frame of some sample file to find if some are lacking, or have been doubled or what....
I assume I would be very happy with just a simple theorical answer either...
So once again, if someone already has been into such questions, I would really pleased him or her to share or report what they experienced. Thanks in advance.

Rendered motion effect looks very soft.

I am hoping someone can explain what is happening. I have a shot that looks great, and when I apply a reverse motion effect, it looks fine, but when I render the entire timeline, the shot looks really soft.
I can lay off to tape without rendering this, but if I export my timelines using compressor, the resulting compression has the same soft shot problem. I am rendering in high precision YUV and motion rendering is set to best.
The quality is not acceptable on that shot, it's night and day from its rendered and non-rendered state, almost like it's being de-interlaced and softened.
SD timeline, Uncompressed 10-bit 4:2:2.

I'll give you a head's start. Select clip in FCP. Right-click and choose Send/To Motion Project.
In Motion, click on the Properties tab in the inspector for your clip. Twirl open the Timing parameter. There you'll see everything you need for a speed effect. Click the "reverse" button to have the clip go in reverse. Under Frame Blending choose Optical Flow. I don't find it necessary unless you're slo-moing the clip though.
Piece of cake.
When you use Optical Flow, Motion has to analyze the entire captured media (I'm sure you know this from Shake). Just a caveat.

Constant speed for an unbalanced load

I have a machine that uses a Dart 253g to drive a dc motor. The arm if an offset arm that rotates.. We have tried to balance the arm the best we could but the load is still off. What happens is as the heavier part of the arm is on the upswing of the motion, the drive cranks up the torque and pushes it up and over the peak of the rotation. The problem is, on the way back down, the load takes off and "freewheels' around until the upswing starts again. Would a constant speed drive help eliminate this? This machine has no feedback on the arm
Thanks in advance
Ken

You will need a regen or 4-quadrant drive to provide dynamic braking. A tachometer will always help with speed regulation(only on the upswing with your current drive, though).

My motor runs at a constant speed

i have a
PCI 7342 controller.
MID 7654/7652 servo motor drive
motion control software
motion assistant 1.1.
I have setup the hardware connection.
When I try to run the motor using the motion assistant the motor runs at a constant speed irrespective of the velocity that I specify in the motion assistant.My motor velocity is 7 voltage per 1000RPM.The motor keeps running at a constant voltage of 25volts.I donot have a encoder but I have a tachometer.
pls help.

Hello Sumitha,
In order to use servo motors with National Instruments motion controllers, you must have some form of position feedback. This is required due to the PID control loop implemented on the controller. Without some kind of control loop, there is no way to guarantee that the motor will get to the commanded position following the specified trajectory. Servo Tune is a tool used to adjust the PID parameters, which in turn control the stability of your system.
If you do not have any way of adding position feedback (such as a quadrature encoder), you will not be able to make full use of your motion controller. It is possible to simply read a voltage in and output a specified voltage from the motion controller. However, you lose all hardware timed control and all the benefits of a motion controller. If you are interested in that option, a DAQ board might work better for you. Otherwise, I highly recommend looking into adding a quadrature encoder to your system.

DC motor - constant speed

I 'm a light user of Labview and need some assistance.
My objective is to make the dc motor retain constant speed even when a load is applied.
The tools I have to acquire data with are:
NI USB-6211
Labview 8.2
Optical Encoder - 1000 pulses per revolution
My main concern is writing the PWM VI to do this.
My first guess is to set use a DAQ assistance to acquire a signal as a counter input from the encoder.
Not really sure what to do with that because I am kinda lost from there.
How would I use that info to adjust the PWM of the output signal?
All help is appreciated.

Hi jgarcia,
this doesn't work at all. Your application requires closed loop control. This means you need deterministic behavior (= stable timing of the control loop) for single point I/O operations. With your setup this is not possible due to the fact, that both the USB and Windows introduce a lot of jitter (using a PCI DAQ device would make things a bit better, but you still couldn't get reliable control behavior on a Windows operating system). For a control system reliable timing is at least as important as proper tuning of the control parameters.
For motion control tasks it's much better to use a device like the PCI-7342, that runs all control operations in a realtime environment onboard. Other options include using a realtime operating system and PCI or PXI DAQ hardware or a cRIO-System with drive interface modules. For a single-axis system, the PCI-7342 is probably the most cost-efficient solution.
Sorry for the negative answer, but with your current hard- and software setup you will could easily waste a lot of time on a poor solution.
Kind regards,

Any way to make Motion Effect work in CS3?

I had some problems with animated motion effects in CS2, but now they seem to be even worse in CS3... Along with all the other CS3 problems I've encountered, I'm considering going back to CS2 - but I thought I'd try here first...
With an interlaced video project (NTSC SD) anything (title, photo, or video) that is put in motion using keyframes for the built-in Motion Effect comes out VERY bad.
I tried a test with a clip that is only three frames long, consisting of white box approx. 100x100 pixels (made via Titler) and starting at frame 0, offset horizontally by 360 and at the 3rd frame (frame 2) offset horizontally by 380. (20 pixel shift)
FIRST PROBLEM: Look at the frame 0 and frame 1 in the program monitor at 100%. Now try any other magnification - completely different results!!
SECOND PROBLEM: To export these three frames, I have to set the work area bar to include FOUR frames, because if I animate motion of a clip and then export, the last frame is SOMETIMES not included in the output file. If you're playing along, output five frames just to be sure.
THIRD PROBLEM: Open the clip in Photoshop. (The only application in CS3 that appears to work correctly.) At first glance, frame one appears to be interlaced because of the motion. But it's not. The second field is nowhere near where it should be in time relative to the movement. If you use an actual photo instead of a white box, you can see how badly it's mangled. (Not just fields in wrong position, but badly mangled.)
FOURTH PROBLEM: Frame 1 and 2 (the 2nd and third frame) are also badly mangled.
FIFTH PROBLEM: The fourth frame (frame 3) consists of the the final resting place of the object - BUT IT SHOULDN'T BE THERE AT ALL! (The 4th frame is blank.)
I know, I know, long rant... I'm just getting so fed up with all of the problems with CS3...
Anyway, are there other alternatives that will work on interlaced video??? (For now, I had to create a different project that was progressive, and render to a temp file to import into the interleaved project. It looks better, but not nearly as smooth of motion as it should be.)

Please provide
these details to help us help you.
Cheers

Motion Effect doesn't always work with Time Remapped clips

Hello all. I used Premiere 4 extensively (yes, '4' not 'CS4') and I'm just getting back in to it with CS6. Lots of cool new stuff to learn but I'm happy to see the basics are pretty much the same!
I'm wondering if anyone has much experience using motion effects on time-remapped clips. If I set 'position' or 'scale' keyframes in the Effect Controls, the changes are not always reflected in the program monitor, depending on the clip. If I try and set keyframes by dragging the video around the program monitor, it puts keyframes in places where I don't expect.
This doesn't affect all time-remapped clips, just some of them. Or maybe it does affect them all, just to varying degrees, depending on how extreme the time remapping is. I'm guessing now.
If I were to speculate further, I would say that the motion effect is operating on the clip before the time remapping gets applied. Again, just a guess, which is why I'm asking if someone more knowledgable has any insights before I pursue this much further..
Many thanks!

Hi Jeff, thanks for your response! Nested clips, you say? I have heard of these things but I can only imagine what they are and how to use them. Sounds like it's time for me to RTFM!
There's so much new stuff, it doesn't surprise me that I have to not only figure out the new feature, but the proper workflow to utilize it. I gotta ask: Do you know of any documents along the lines of "how to use modern premiere from the perspective of an antiquated premiere professional"? 4.2 was my bread and butter for many years and I knew it like the back of my hand. As such, it's kind of hard to stay awake sifting through Adobe's docs which generally assume no prior knowledge; although you giving me a place to start is a big help! But like I said: I gotta ask because it'd be great if there was something just for 'people like me.' (ain't it always the case? )
Again, thank you.

Editing stills with motion effects, performance questions.

I am editing a video in FCE that consists solely of still photos.
I am creating motion effects (pans and pullbacks, etc) and dissolve
transitions, and overlaying titles. It will be played back on dvd
on a 16:9 monitor (standard dvd,not blueray hi-def). Some questions:
What is the FCE best setup to use for best image quality: DV-NTSC?
DV-NTSC Anamorphic? or is it HDV-1080i or 720p30 even though it
won't be played back as hi-def?
How do best avoid squiggly line problem with pan moves etc?
On my G-5, 2gb RAM, single processor machine I seem to be having
performance problems with playback: slow to render, dropping frames, etc
Thanks for any help!

Excellent summary MacDLS, thanks for the contribution.
A lot of the photos I've taken on my camera are 3072 X 2304 (resolution 314) .jpegs.
I've heard it said that jpegs aren't the best format for Motion, since they're a compressed format.
If you're happy with the jpegs, Motion will be, too.
My typical project could either be 1280 X 720 or SD. I like the photo to be a lot bigger than the
canvas size, so I have room to do crops and grows, and the like. Is there a maximum dimension
that I should be working with?
Yes and no. Your originals are 7,000,000 pixels. Your video working space only displays about 950,000 pixels at any single instant.
At that project size, your stills are almost 700% larger than the frame. This will tax any system as you add more stills. 150% is more realistic in terms of processing overhead and I try to only import HUGE images that I know are going to be tightly cropped by zooming in. You need to understand that an 1300x800 section of your original is as far as you can zoom in , the pixels will be 100% in size. If you zoom in further, all you get are bigger pixels. The trade off you make is that if you zoom way out on your source image, you've thrown away 75% of its content to scale it to fit the video format; you lose much much more if you go to SD.
Finally, the manual says that d.p.i doesn't matter in Motion, so does this mean that it's worth
actually exporting my 300 dpi photos to 72 dpi before working with them in Motion?
Don't confuse DPI with resolution. Your video screen will only show about 900,000 pixels in HD and about 350,000 pixels in SD totally regardless of how many pixels there are in your original.
