Variable speed and advanced keyframing

So I'm trying to figure out how to do something complicated and I'm not sure if its possible in final cut, but if not maybe someone can point me in the right direction. Lets say for example I have a video of a pulsing light that dims and brightens regularly and an audio track with an irregularly placed noise with silence in between. I want the pulsing light to be aligned with the audio waveform so that the peak of the brightness is aligned with the sounds.
I guess I'm looking for a way to keyframe the video speed, which I'm not even sure if you can do in final cut. But I'm also wondering if I could possibly write a script to have it pick out keyframes based on the peaks of sounds or brightness. And is there a way to make it variably match up the speeds so that audio and video keyframes are aligned? I'm very confused here as to how I would go about this. Any help is appreciated.

If you can wait for Motion 3... you can do what you want almost instantly... it's pretty cool...
Otherwise, FCP isn't scriptable. so it's a frame by frame sort of keyframe thing you need to do... pretty tedious, but probably the only way to do what you want.
You can change the speed of a clip with keyframes ... read about "Time Remapping" in the FCP manual availalbe in the Help menu for quick searching.
But if the video doesnt' really move at all couldn't you just cut it in to the beats you want it to brighten on? I'd think that would be easier.

Variable Speed and/or Frame-by-Frame Video playback with Waveform synchronization

I'm using Diadem 2011 to view data recorded in a LabVIEW Module that we have written. The function of our LabVIEW module is to simultaneously capture video from two infrared cameras and 8 channels of waveform data from a DAQ and record this data to disk. Data is recorded as two separate AVI files (compressed) and a TDMS file (using TDMS logging). Using Diadem, I use the video synchronization function to view the TDMS data and video files. I can scroll a cursor in the waveform data panel and view the video corresponding to the time selected.
I am looking for two features from Diadem that I am not sure are present: 1) A way to vary the playback speed from real-time. 2) A way to advance the video in a frame-by-frame manner. If anyone has any suggestions on how I might implement this in Diadem 2011 or can verify that these features are present, I would very much like to know.
Thanks in advance.
Solved!

Hello Resaebiunne,
All the functions you are looking for are available in the VIEW toolbar.
For the frame reverse/forward functions, please make sure that the section with the video inside is highlighted and then use these two buttons. The "Cursor Parameters" icon let's you change the playback speed.
Hope that helps,

How to get speed and influence of keyframe?

Hi everyone,
I'm sorry if my question is due lack of understanding scripting in AE but I can't seem to get speed and influence properties of selected or nearest keyframe, I found only the ways to set those.
Can anyone please point me in right direction?
Thanks!

property.keyInTemporalEase(key) and property.keyOutTemporalEase(key) will give you the ease objects with speed and influence attributes for a particular key.

Copy and Paste Variable Speed Ramp Curves?

Is there any way to copy and paste variable speed ramp curves from one shot to another.
I've got a rough cut with lots of speed ramps, and now I have to conform renders that came back from Color (pre-prepped with out ramps) to the offline with the same frame ramps.
I can't seem to do it any other way than by eye match, which is less than great.

Query about User Variables and Advanced Actions

Hello,
I am creating a clinical-based project using Captivate 5.I have to give you quite a bit of information before I can pose my questions so please bear with me.
Users have to select multiple options from a checkbox widget (shown below).
Each options, for example 'location' is associated with a variable for example 'hpi0' (See below):
Each option has addtional data associated with it:
Location = hpi0 (user variable)
Location data = hpi0data (user variable)
Please see the screenshot below:
Notice in the image above that I have created a conditional advanced action - if the user selects Location (hpi0) on the checkbox widget, the data associated with that variable will be presented to them. That data (e.g. location data or hpi0data) is presented in a caption text box in the following slide. (see below)
I hope I have given you enough information.This is a complex project and this is just one of my many problems.I have had to create over 200 hundred user variables and more than 6 Conditional Advanced Actions in one project. The project is becoming unstable. So here are my queries:
1) Are there limits to the amount of user varables I can create in a project?
2) If so, how can I re-use the user variables I have already created? Otherwise I will have to divide this project into 3 parts and I want to avoid doing that.
3) Are there limits to the amount of Advanced actions I can create in a project?
Again I am using Captivate 5 for this project.
Any assistance, tips or tricks would be greatly appreciated. I am learning captivate as I go so If there is away to streamline this process, I am open to any suggestions.
Thanks

Hello Tinukwa
This is indeed a challenging project, and although I did create a lot of projects with advanced actions, they were never that size. You have to listen to Jim's words about using some widgets, he is a widget specialist which I'm not. I do not know if you are aware of the fact that the checkboxes widget coming with Cp was extended by Jim? He offers it on his website, I blogged about this extension and suppose you do know my blog. About the advanced actions, perhaps I could help but only screenshots are bit limited. So I wonder if either I could have access to the file and/or if we could have a Connect session eventually?
First intuition tells me
we should look to re-use variables, but I do need more information; do you need the vars XXXXdata somewhere else later? If not, perhaps only to display it you could use one variable; now you keep the information chosen by the user in 2 variables: hpi0 and hpi0data (isn't that redundancy?)
and by choosing labels for variables, actions and objects in an intelligent way reduce the editing time because you'll need a lot of almost identical advanced actions. Usually I do a lot of reflection before starting to create labels, variables and actions.
About re-using what you already constructed: as I explained once, a template is the only way to be able to re-use a script at the moment. And Kevin Siegel discovered (so gratefully for that) it is possible just to change the extension of a standard CP file to cptl to have a template.

PS Jim suggest also to split up the project? Here I'm not sure if that is really needed.. should have been the case for previous versions.

Keyframing variable speed

Hey I posted a question about this earlier but it wasn't answered very well. I'm edIting a music video and I'm having trouble slowing down a clip and speeding it back up (I'm doing this by cutting it up into 3 pieces and changing the speed on each one.) my first question is: why does it move everything on the timeline when I change the speed it shifts everything further down the timeline. The reason I'm asking is because I used to use adobe premiere and when I would slow down a clip it would just make that clip smaller or larger and not affect every other clip on the timeline. Anyone know why this happens? My second question is: does anyone know of any good places to watch tutorials on speed change for free? Thanks guys!

I personally find it a lot easier to use the clip keyframes in the timeline. Enable clip keyframes using the button at the bottom left of the timeline window, then use the pen tool to add keyframes where you want them and drag left or right to move that frame and adjust the speed accordingly. Hovering the mouse over the keyframe shows you the speed and duration to the left and right of the keyframe.

Variable speed on Audio and Video

I want to do a variable speed ramp using video and audio, but when I use the graph it only applies variable speed to the video ( it does constant speed fine to both)
Any help ? Thanks
Deyson

I see other people have this problem but I can't find the solution. It's occasional buzzes on the speakers when I'm watching a video. The mouse momentarily freezes--fraction of a second--and the video jumps. Sometimes the busses are pretty quick and have a slightly different tone.
Any help?

Can't select "Variable Speed" for Still Image Motion

I am using FCP 5.1 to add motion to still images. I've placed my still images on the timeline and added the appropriate keyframes in the Motion tab of the Viewer to Scale, Rotate, and move the stills on screen to my liking. But the speed is locked to "Constant," and I want to change that.
Specifically, am rolling a still image on-screen, freezing it in the middle of the screen a few seconds, and then rolling it off-screen. Doing this is easy: I just add a keyframe and type in the off-screen coordinates, then add another keyframe and type in coordinates somewhere on screen. But I want to vary the speed that the image rolls on-screen, so it moves on-screen quickly but then gradually slows down until it finally stops (freezes) in the middle of the screen.
Unfortunately, the "Setting" popup menu under "Time Remap" in the Motion tab of the viewer is grayed out and locked to "Constant Speed" (and yes, my still image clip is indeed selected and being displayed in the view). I cannot figure out how to unlock that popup so I can select variable speed.
I can choose Variable or Constant speed just fine for any imported "video" clips -- only still images are locked to Constant for some reason. Is this just a feature limitation of FCP 5? Any ideas would be appreciated.
Many thanks.

Why so much sarcasm in this FCP forum, Studio X?
Yes, it was in the manual, which by the way is quite large. And I didn't say how long it took me to spot that in the manual either -- a long time. I didn't spot it the first time I had read through that section (yes, I had read it before). And the fact is, you didn't know it either, otherwise you may have cared to point it out (for not only myself, but for others reading this forum too).
I participate in numerous other forums on other sites. Many times, people ask questions that are very simplistic to me -- I know the answers and I know those people putting forth the questions could easily have looked up the answer. Nevertheless, I take time to be helpful to others. For truly, some day I may be in their shoes, lacking time to read every part of every manual out there.
I am therefore thankful to those who likewise respond in a tactful manner to my queries, with the productive aim of helping others rather than condemning them. Thank you, David Harbsmeier, for being consistently positive and very helpful in this forum!

Set variable speed?

Help!
I am having trouble plotting variable speed in Final Cut Pro.
I go to 'time map' and look at setting keyframes to control speed but it seems to be really imprecise and random. There doesn't seem to be a way to set precise values eg. setting the clip to ramp from 0% to 400% or down from 100% to 50%. Or even set 1000% to 3000%.
And when i plot keyframes in 'time map' it doesn't seem able to tell what the speed value is that's being set.
Any ideas?

Chances are you'll need to export out the sections of a clip that you want to remap.
FCP will look at the entire clip to extrapolate the remapping.
IOW, if you're trying to remap a :30sec section of a 20 minute clip, FCP will apply it's remapping to the entire 20 minutes.
So just export out your :30 (with a bit of handles for good measure), bring it back in and remap that.
Post back if it doesn't fix it for ya.

Variable speed in FCE

Can one create a variable speed clip? Say start a 100@ at the beginning of the clip and end at 75%?

No, the ability to keyframe speed is a function reserved for Final Cut Pro. However, you can try using Piero's [Time Remap|http://web.mac.com/piero.fiorani/PieroFFCE_Effect/TimeRemap.html] filter to get a similar effect.

Exporting variable speed slo mo to Motion for optical flow, how?

Greetings,
I have FCP 7 and Motion 4. I am new to using Motion. I want to either export a variable speed clip from FCP to Motion and add the optical flow feature, or build a variable speed change in Motion, but I can't figure out how to do either!
The 20 second clip is in reverse-slow-mo, and progressively gets slower (from -38% to -4%) as set in FCP using keyframes. When I "send" the clip & it opens in Motion, the in-out points aren't recognized, (the whole unedited clip shows up) and when I set the timing to "variable" in the inspector, (under "timing", for time remap) the clip disappears in the timeline altogether.
I've also tried to create a QT of the clip as 100% but in reverse (just to have less to build in Motion) but I cannot figure out how on earth to use the graph in Motion (under time remap, variable speed) to create a variable speed change to progressively slow down. This is the key issue for me-- how to create variable speed change in Motion??
I tried one other thing in Motion, the "add behavior", and added "Speed Change", couldn't figure out this method either-- how to make clip progressively slow down, and also how to apply the optical flow to that speed change (seems optical flow only works with time remap method?) Any help would be greatly appreciate.
AKJ

Although it does occur, the media isn't ALWAYS mangled... did you try workflow 1 above?
As far as I can tell from your description, baking the speed change in before sending to Motion is not going to work as the clip will already be retimed.
I agree, changing versions mid project is a bad idea. When faced with this recently, I bought a $50 500gb hard drive, installed Leopard and the new version of Final Cut Studio onto it, booted into that drive, opened up a COPY of my project in the FCP7 and did what I needed.
I found no issues, so just continued in FCP7. However, if I did find issues, I would have done only what I needed the new version for, then rebooted back into the drive with FCP6, opened my original project, then imported the results.

Looking for a Motion 4 Variable speed tutorial

Can anyone give me a link to a video of a Motion 4 Variable speed tutorial. i want to do the Twixtor keyframing thing but in Motion 4.
Thanks.

There's your solution, buy them. Then figure out how they were made after your need has been satisfied.
While there is nothing absurdly difficult about their templates, motionvfx charges good money because they've done excellent work. You could replicate several of the items for sale if you have many days to not only learn how to drive Motion's interface but to control its many nuances. It is in the subtle and skillful manipulation of the extensive controls and behaviors that allow the competent user to elevate their work beyond the pedestrian.

Cross Dissolves dont work on Variable Speed clips?

Whenever I add a cross dissolve a the end of a clip with variable speed the dissolve doesn't work. Any reason?

A workaround:
1) Put your variable speed clip on V1
2) Overlap the incoming clip on V2 so there are the same number of frames of overlap as the desired length of the dissolve
3) Using the Pen Tool in the Timeline, add two Opacity keyframes to the clip on V2 and, placing the first KF on the first frame of the clip, ramp the Opacity up over the number of frames of the desired dissolve
4) If you need the clip that is on V2 to end up on V1 for further editing in the Timeline, create an Add Edit in the clip and Shift-drag the second portion of the clip down to V1 so it doesn't change its horizontal position in the Timeline

W520: How to get full speed and turbo on battery power

Here is how you get around the on battery max frequency limitation (of 1.2 GHz, at least for my i7-2620M) and no turbo (well, almost, read on):
0. Assuming you have max performance enabled everywhere possible (BIOS/PowerManager/Windows Power Scheme)
1. Load ThrottleStop.
2. Set the multiplier manually to your maximum multiplier (e.g., 27x for i7-2620M, 23x for i7-2820QM, etc...) or Turbo (which is the setting after your max multiplier).
3a. Enable ThrottleStop
3b. (optional) Check in CPU-Z and make sure that your highest multiplier is being used when the CPU is utilized. If you selected Turbo, you should have turbo enabled at this point.
4. Disable ThrottleStop
5. Exit ThrottleStop, so that it doesn't waste any battery power, since it is no longer needed
This will change the max frequency (and max multiplier) available from whatever Lenovo decided to arbitrarily fix it at (e.g., 1.2GHz) to the correct max frequency (which in my case is 2.7 GHz / 3.2 GHz for turbo). Now your laptop will be able to correctly go from 800MHz to whatever is the max frequency of your CPU, using both EIST and C1E. Turbo will also kick in, if you enabled it in ThrottleStop and the Lenovo PowerManager app will even show it as enabled.
Thanks Unclewebb for letting us get around this stupid max CPU frequency limitation that Lenovo has imposed on us.
Disclaimer:
Do this at your own risk, since Lenovo does not officially support it.
Turn on active cooling, if you do CPU intensive stuff for any prolonged period of time. This will take away some on battery time, but if battery time is of ultimate concern to you, then this change is probably not for you to begin with.
If you go through prolonged periods of CPU intensive activity, you will lower your battery life and produce a lot of battery heat, because you will have a relatively high discharge rate. A high discharge rate reduces both the number of charge cycles and the maximum charge capacity of a Li-Ion battery. I don't know how safe all of this is, so do this at your own risk and probably monitor temperatures along the way. Other laptops can do Turbo and full speed on battery power (e.g., the slim 3 lb Sony Z, with the i7-2620M), but then other laptops have different designs and cooling systems, so who knows how the Lenovo W520 hardware will react to this.

Hi,
I have the opposite problem - my i7-2720QM is fixed at 2.2GHz no matter how hard I spank 1, 2 or all cores, and no matter what System Performance settings I apply. It even runs at this speed, and gives the same bench marks when on battery with the "system performance" set to Low.
No one even knows what the various System Performance settings actuall mean. E.g. Neither Lenvo support nor these forums could tell me what the difference between "Maximum Turbo","Turbo" or even "Low" under "System Performance" in the Lenovo power manager Advanced settings.
I have been trying go get turbo boost to work for 2 months. I have wasted so much time with this machine, I could have bought 2 Macbook pros for the cost of the time lost.
I dont know why Lenovo have disabled the turbo boost (and the opposite, turbo drop?) feature for this CPU - is it deliberate, or incompetence? Its certainly false marketing and extremely annoying that I have to use my ancient PC to do single threaded type work which I know the Laptop can manage if it were not crippled.
So people whos clock speed drops when on battery are the lucky ones. Mone doesnt even if I want it to.
