Pixel Motion with time remap. Am I missing something?

I have a 720p 59.94 fps clip of an rc quad flying. Ive time remapped it and applied Pixel Motion but the little quad chops very badly while the background is very smooth during the slowest part of the time remap.
As a control measure, I did the same clip with only frame blending, no Pixel Motion, and the quad is smooth, however the whole scene isnt as clean as would be with Pixel Motion.
Am I missing something?
Heres the two clips; the 1st one is frame blending, the second is frame blending/Pixel Motion. Why does the subject(quad) skip badly?

It's inherent in how the two two methods work differently - one favors large, contiguous areas, the other works better with only tiny motion differences. The problem is that when using pixel motion to the algorithm your copter doesn't move much. No motion, nothing to blend. You can always try the Timewarp effect and tweak its parameters, but short of masking the copter and combining the two you won't get a perfect result, either, most likely.

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.

New development with time remap tool

It turns out my time remap tool works just fine in other projects just not this one. I do have alot of still shots with some motion graphics which is starting to extend my render times extensively. My question is, how do I solve this rendering time problem? Is there a way manage rendered footage better? Compress it? I'm new to this motion graphics and would appreciate any help.
thanx
John

John,
Keyframing smooth moves takes a little bit of practice and a BIG Canvas window to really see what you're doing. You'll be using the Canvas window and the Motion tab of the Viewer window a lot for this.
Once you have the Canvas window up-sized (but still keep it at "Fit to Window" or smaller), set it to Image+Wireframe mode. When you click on or highlight a clip in the Timeline, you should see the Wireframe for that clip in the Canvas window (as long as the playhead remains over that clip). But first, double click a clip in the Timeline to load it into the Viewer window then open the Motion tab.
Depending on what you want to do, you can approach most keyframed motion tasks two ways; move the Wireframe in the Canvas window, or enter values in the Viewer window. I usually do a bit of both.
When you set a keyframe that shows up as a green dot (Scale, Rotation, Crop, Opacity, etc), you can right-click on that keyframe and select "Smooth" from the contextual menu. You'll see the purple bezier handles added to the keyframe. You can leave them as they are, or you can move those handles to manipulate the desired action. But for items like the Center control (black dot keyframe), you don't have this option in the Viewer window. Say you want to move the center point over the duration of the clip. Set the beginning and ending keyframe - or just set the beginning keyframe then move the playhead to the end point and manually drag the Wireframe in the Canvas window to the new location and FCP will automatically add a new keyframe. You should now see the path of the clip shown in the Canvas window displayed as dotted line. Right-click on the end or beginning keyframe and select "Ease In/Ease Out" from the contextual menu. Now you should see the same purple bezier handles added. Again, you can use the handles to smooth out movement, or slow down or accelerate a clip (by extending or shortening the length of the handle). If you have a multiple keyframed motion path, you can make wonderfully smooth curves with the bezier handles.
For more info, look up Bezier in the user's manual, or better yet, go to Amazon.com and buy Kevin Monahan's book; "Motion Graphics and Effects in Final Cut Pro."

Expression help with time remapping

Hi
I have a 25fps Precomp with an animation that changes on every frame.
In the master comp I want to apply an expression to its time remap property so that it holds on each consecutive frame for a given duration, eg on Frame 1-15 we see frame 1 of precomp, on frame 16-30 we see frame 2, and so on. I can't figure this out. Tried posterizeTime and some other bits to no avail and can't find it elsewhere on the web.
Thanks, Steve

<Big sigh of relief> Thank-you Dan.
I read your expressions everywhere on the web and when I need a little help you are there within MINUTES!
You are such an asset to the AE community.

Media Encoder fails with Time Remapping

There is a single 1 Minute Clip in the PR CC 2014 timeline, with some time remapping effects. Exporting with Media Encoder CC 2014 SLOWS DOWN speed of the clip after approx. 30 sec unintentionally and therefore gets out of sync with sound, and ends at a complete different frame than in the timeline.
However, exporting directly from PR CC 2014 gives correct result.
Anyway, this looks like a major "feature" of ME!?!
(MacBook Pro 2013, 15", 2,6 GHz i7, OS X 10.9.4)

source is an uncompressed HD 1080 QT .mov file rendered from AE.
sequence settings are 1920x1080, 25fps, square, progressive
export settings are QT, H.264, 1920x1080, 25fps, progr, square, 20000kbps

FCP XML to Flint - Problems with Time Remap

My Flint artist and I have had some problems with the XML Export and Import that we cannot figure out. The XMLs from FCP sequences that have variable speed Time Remaps applied show up on the Flint with those particular clips with the wrong in/out points in both the source and record times. Also, the speed ramp info doesn't show up properly.
We have followed the Flint manual to a T on importing correctly. Anyone encountered this or know a solution? Especially why it's throwing off the in points. It screws the whole timeline when that happens.
Thanks in advance.

The TimerEvent target is a flash.utils.Timer object and does
not contain a reference to your lblTimeUntil label.
Recode
trace("Seconds Left" + evt.target.lblTimeUntil.text);
to
trace("Seconds Left" + lblTimeUntil.text);
and you will not blow up anymore.
This code will display the count up till refresh.
public function onTick(evt:TimerEvent):void {
var minuteTimer:Timer = evt.target as Timer;
lblTimeUntil.text = minuteTimer.currentCount.toString();

Fiters applied with Time Remapping don't work?

Guys,
I'm finding when I use the "Time Re-Mapping" on a clip and then apply another key-framed filter it doesn't work .. although they do work if you don't key frame them. I guess it kind-of makes sense... but is this purely because the clip is time-remapped? Is this a 'bug' or is it like that with any NLE? As a work-around, I can export that time-remapped single clip to an AVI (or other format), re-import the now remapped clip and apply the key-framed filter and it works fine .. which I suppose proves my hypothesis.

The way Premiere works.... probably so. I think it could be reasonably argued either way. If it is "normal", I guess I'd like to see an error message or something say "hey, you can't do that on a time re-mapped clip" .. or something like that.
But then, I'd like to see a progression bar fill up as AME loads a project too just so I'd have that warm & fuzzy that something is happening and know my machine hadn't frozen.
Thanks...

Keyframe irregularities with time remapping

Just thought I'd post a screen grab of keyframe issues I've been seeing in case anyone at Adobe is paying attention. I can't recreate these bugs as they seem to only happen once in awhile. In this screen grab my selected clip is 00017.MTS and it's effect conrols are open in the source side monitor. At the point of the playhead the opacity is set to 0% but it is not fully transparent, it's opacity seems to be more like 50%.
My system:
Adobe CC Premier Pro
Macbook Pro mid 2012
2.7 GHz Intel core i7
Nividia GeForce GT 650M 1024MB
OS X 10.8.5

The workaround is to do your time remapping keyframes and then nest it into a new sequence. Then apply the opacity keyframes to the new sequence.

Motion/opacity (still) not working when using Time Remapping

Okay: here's my beef. This bug has been around since CS3 and definitely CS4. I was hoping it would be fixed with the arrival of CS5, but apparently it still has not been resolved.
If you use Time Remapping in PPro, you can't use any of the other keyframing features, such as motion or opacity. If you do, the video simply disappears. Rendering won't help either. The only way to get Opacity to function is to superimpose a bar of black video on top of the clip (or any other color matte if you like it fancy) and have the Opacity on that clip work in reverse. How to get motion within such Time Remapped clips to work is still a bit of a mystery to me...
Has anyone else found this tedious/annoying/irritating?
So, dear Adobe, when can we expect a fix for this? Hopefully before CS6...
Thanks much.
Richard

I have this same exact problem in CS6.
It definitely has to do with time remapping. I have used Opacity keyframes EXTENSIVELY in this film I'm editing, and suddenly when I apply time remapping keyframes, I can't use opacity on them. Ouch!
My solution was (In case someone Googles for a solution and finds this, like I did...) to delete all effects and time remapping, apply the Opacity Keyframes FIRST and THEN add the time remapping last.
Hope this helps.

Has anyone seen this BUG with Time Warp and Dissolve?

I'm doing some real basic slow-mo clips, transitioning with various dissolve wipes. I've come across a problem that is extreemly frustrating! I'm wondering if anyone has insight on a fix or if Adobe does service packs or fixes that I might be able to install.
If you put two clips adjacent to each other on a timeline, apply time warp, set percentage to say 30% of realtime, then apply a dissolve between the clips, clip B, the outclip will play in reverse for a period equal to about 1/3 of the duration of the clip.
This is true scrubbing through the timeline and even rendering.
VERY ANNOYING!
I'm going to call support tomorrow, but that's not going to help me get my project finished any sooner since this is a critical element in this composition. I've tried the time remapping method, but the frame-blend is no match for the pixel motion of time warp.

Steve,
I think your post #11 was being sarcastic, but you left a little wiggle room for it not to be. With the sarcastic interpretation, I must add my thoughts:
Here is the link to the Adobe bug report form
. It is important that users who discover bugs with reproducible steps file them - otherwise they don't stand a chance of ever getting fixed. Steven Gotz's advice was sound in this regard.
As to the discussion of workarounds - since this is a User-to-User forum, the best that we as a community can do is help each other out with workarounds, since none of us here have the power to actually fix anything.
The important thing to glean from SG's post is the definite need to file a bug report.

Need help with speed remapping

So here is my question. (check pic below to see timeline)
I'm working on a timeline and I have a clip somewhere in the middle of this timeline. Now I've put the two markers which close off the area of the clip that I want in slow-motion. And then I drag the rubberband now to 50%. This causes the clip to obviously become longer.
But the problem is that it doesn't push the clip that comes afterwards, it just sort of submerges and I lose a part of the clip that I put into slow-mo.
http://gyazo.com/0cce5ab07e22897f21a25e3308a9cbb5.png Here's a picture of my timeline.
So my question is how can I make it so that the clip after is pushed forward automatically?
I know how to fix this problem with some dragging and pulling, but I want to become as efficient as I can and don't get into any bad habits.
Thanks!

If all you want to do is simply slow down or speed up a clip, use the Speed/Duration settings--it's probably the simplest way to induce a speed change. This is a constant speed change, which you can also do with Time Remapping--which is what I think you've been doing.
The benefit of Time Remapping is that it allows for variable speed changes within a single instance of a clip. Say for example you want your clip to start at 100% speed, slow down immediately to 25%, and then speed up immediately to 200%. You can do this with Speed/Duration, simply by razoring the clip at the specific points where you want the speed change to occur, and then altering the Speed/Duration setting for that instance of the clip. With Time Remapping, not only can you do this without having to chop up the clip, but you can also create "ramps" from one speed to another--hence the variable speed aspect. You can even freeze a clip or reverse it, all without editing the clip into smaller pieces. This can result in a much smoother effect, but it might not always be what you're after. Time Remapping does have a bit of a learning curve, but it really is the more powerful option of the two. You just have to decide which is better for your purposes.
An additional benefit, and I might be wrong on this, but I believe that using the Time Remapping function results in (theoretically) a higher quality speed change effect due to a different algorithm or some-such. It uses some different techniques to generate the interpolated frames created in a speed change, that should look smoother than if they were done with the Speed/Duration command.
Hope the helps a bit.

Explain Variable speed using Time Remap?

I'm trying to do slow motion using time remap, but every time I raise or lower a keypoint from the slope it either goes in fast motion forward or fast motion reverse. I thought if I lower the keypoint from the slope it would go in slow motion. Can someone explain this to me.

With the time remap curve you define which frame is played back at which time. When you open up Time Remap you'll see a curve (a straight line) going from 0 to 999. The curve goes steadily up, which means that the time goes forward. When you change the curve so it goes downwards, then time will go backwards. A flat line from the left ti the right means that no time passes and you will see the same frame for the whole time.
So remember:
- Curve goes up: Time goes forward. The steeper the line is, the faster time goes forward.
- Curve goes down: Time goes backwards. The steeper the line is, the faster time goes backwards.
- Slow Motion: Make the line go just a little bit up from the left to the right. The less is goes up, the slower time will pass.

Time-remapping audio artifacts - pops/crackling/static

I'm still not entirely sure why it happens but when I slow footage down with time-remapping in AE CS5-6 I can most of the time get these 2-3 frame audio popping sounds ( best way I can describe it, you could also describe it as a static spike or crackling sound, something that is noticeable different from the slowed down audio ). However I don't get it at anytime during ram previews, I'm only hearing them with rendered footage. Normally I'd just take those rendered clips and reduce the audio levels for those 2-3 frames but I'd like to see if there is a way to avoid it entirely.
I've tried rendering in various codecs and matching the source footage settings exactly but haven't had any success in that direction. Again it's not in the source and it doesn't show up in ram preview, only after it's been rendered do you hear any of it. Any input and possible alternative approaches to solving this issue would be great I've run out of stuff to try.

I don't believe the source is using MP3 or AC3 for the audio but I do believe it has some slight compression. It's nearly lossless so I don't understand why rending something with heavy time-remapping using something like Lagarith would cause these types of artifacts.

Time Remap Expression

hi there
I'm doing an Airport destination panel animation.
I've got a Composition called 'Flip' with Time Remap enabled.Here takes place the whole 'fliping' animation. This comp has got a Text Layer with an expression applied to it.This expression cycles through this line of code=>
letters = "1|2|3|4|5|6|7|8|9|0|A|B|C|D|E|F|G|H|I|J|K|L|M|N|O|P|Q|R|S|T|U|V|W|X|Y|Z|-|.|/| ";
So every 5th frame the next Nr./letter appears.Example=> Nr1 appears completely at frame 5,Nr4 at frame 20 and so on.Animation is 4 frames long.
Now,it would be great to have Time Remap expressions that would do the following=>
let's say i want to write the word CLOSED=>6 letters
i now need 6 flip comps for this.Yes,i could now use Time remap keyframes to go to each letter of course.But in my project
i'd have to do it 400 times or more.
Is there any way to go to each letter>hold the letter for a specific time and switch to the next letter via expression?
//expression
Letter: A;// for example
SwitchToNext_letter; B;
Switch_time:.5 seconds
stop time;
any help appreciated
cheers

If one or more of your subcomps doesn't start at time zero as a layer in its parent comp, you have to compensate for that. It's tricky with multiple levels, but basically you end up with something like this:
a=comp("Diane - AE Rig").layer("Body_CTL").effect("Mouth_Control")("Slider")
framesToTime(a.valueAtTime(time + some_offset))
