CS5 time remapping issues

I have two problems with Premiere CS5 time remapping causing errors
When I apply a normal speed change using the duration box from the pull down menu, the speed does change and the clip plays fine.
When I apply the time remapping feature from the timeline, the clip either plays at the normal 100%speed and ignores the keyframes or it plays an altogehter different clip.
I am editing HD footage 1920x1080 from a Sony Z1u captured via blackmagic intesity as motion jpeg.
If I change the duration of the clip to 101% the keyframes are applied but the video is choppy and impossible to watch.
The problem is unique to CS5 as far as I can tell, I used CS3 before with the same setup and that function was fine, but I have some avchd footage in this project and so I switched to cs5.

Any help would be appreciated.

Thanks for your post Harm. It is good to see that you still troll the forums. You have helped me several times in the past.
Using the blackmagic card solves a couple of problems. ( in theory)
First it gives you a true 1920x1080 video capture instead of of the hdv space.
Secondly the mjpg functions as an intermediate so that the processor does not have to decompress the footage from hdv on the fly, and it takes up less HD space than 8bit uncompressed would.
In addition the BM card allows for HD monitoring on an external HD TV and surround sound system for 5.1 audio.
I have discovered a workaround for the time issue, and that is to apply an affect to the clip and it forces premiere to render the clip and that seems to fix the time issue.
The black magic website probably explains this better than I can. But under CS3 which I moved from a few months ago, the combination really worked well.

Time remapping issue

I have a clip that I want to play at a regular speed and then slow down at the end. When I make keyframes and adjust them in the time remap menu box I am running into problems with it slowing down to the desired speed but then speeding up the last couple of frames. What gives?
PS I have already watched Captain Mench's video....

It's a difficult concept. Your clip is, say, 120 frames, four seconds long. If you change the frame rate to something else, all of those frame must still play. You can get around this at least two different ways. Place your clip in an empty sequence and make your adjustments. Copy and paste only the piece that you want back into your main sequence.
Or you can place one additional time remap keyframe just a few frames before the end of the clip. This forces all of your unused frames to play between the second and final keyframe.

Is there a time remapping issue in After Effects CC?

I use time remapping for mouth animation among other things. I have 15 mouths that I was using with the “toggle hold keyframe” selected and “preserve frame rate when nested” box checked. I had been working for about 12 hours (always replaying each sentence after animating it. Out of nowhere, I went back to check the last sentence I had just animated and it was all messed up - replaced with random mouth shapes - not the ones I chose. Then I went back to the beginning and it changed the first several hundred time remapping key frames to the same shape. I’m freaking now because not only did I lose the work but how do I know that if I redo it it won’t just happen randomly again? I’m using a mid 2010 Mac Pro with 96 GB of ram. Thanks for any info.

Thank you very much for your responses! Dave LaRonde, I'll be sure to give more spec info up front next time. Mylenium and Rick - makes sense, I'll keep that in mind going forward.
Luckily, and I totally forgot this in the moment, I turned on Time Machine that morning after months of having it turned off for hard drive space reasons - and so I’m back in business!
Thanks again Gents

AE CS5 Time Remapping Keyframes missing

Does anyone know why the keyframes are not automatically inserted at the in and out points of a clip after selecting layer,time, time remapping?

Keyframes aren't inserted at the In and Out points of the layer; they're inserted at the beginning and end of the layer.
Is that not what you're seeing?

Time remapping issues

Has anyone had this problem?... I open an old FCP file to make some changes, but when I play back the timeline, some sections appear to have been speed up via time remapping. I end up trying to re-edit the whole thing. This has happened on at least 3 occasions.
Any help or guidance would be appreciated.

Premiere Pro CS5/Twixtor Time Remapping Issue

Hi,
Would like some help on this issue if possible thanks
Anyway. Right now I am playing with Twixtor and applying the slow motion effect to one of my clips. However, I am experiencing some issues as the more I slow motion certain parts of the clip, the clip as a whole shortens from its original length. Intuitively, I went to my timeline and clicked on the right hand edge and attempted to drag it out in order to extend the clip. However, It won't expand as I thought it would . I know this issue is easily solvable, can somebody lend me a hand?
Thanks.

Your intuition to lengthen the sequence is sound since the plug-in is not able to change the length of sequence as required if you are trying to slow it down. There are a couple of ways to solve this. See this video starting at 3:42:

Time remapping issues Premier Elements 11 windows 7 PC

I submitted some clips into my timeline that are about 2 minutes long. I used the remapping tool and specified that the whole clip be played in 10 seconds. It works. The problem I have now is a grayed out clip that follows the remapped clip and plays as a blacked out screen until the next clip comes into play. I am assuming this is the unused time slot from the remapped clip. I have tried to move my clips in front or behind the grayed out clip, and tried deleting and closing the gap. Nothing is working. How do I resolve this issue?

Interlaced DV PAL flickering preview time remapping video in AP CS5

Be faced with this problem, i was really surprised. I was working with HD 50p video and had no problem with slow motion. But yesterday i captured some old DV footage 25i and used time remapping to slow it. I saw surprisingly ugly flickering video in preview window!
I exported it into file and it was perfectly OK, i made output to TV though IEEE1394 adaptor - smooth nice slow motion.
But i cannot see this smoothness in preview window.
Before i used CS3 Premiere, and there was no such problem.
Finally, help me

Why are you talking about quality ? Everything is pretty fine, except of one case -> preview window in Adobe Premiere CS5 and time remapping effect of DV PAL in it. It's flickering.
I have read about this problem in some videoediting forums to... so i'm not alone.
But you confirm that it is not Adobe Premiere internal problem ?
by the way, what is OE ?

Time remapping lip sync issue.

I'll try to explain this the best way I know how.
I created a pre-comp for my character mouths (as shown in the picture below). I then created a Null Layer and parented the Time Remapping of the mouth pre-comp to the Null Layer "rotation" using the principals of this video:
Part 1: "Using Time Remapping For Lip-Sync Part 01"
https://www.youtube.com/watch?v=c5GIOtfYWpQ
Part 2: "Using Time Remapping For Lip-Sync Part 02"
https://www.youtube.com/watch?v=NNJgUz1t2rU
I'm sure this is not new.
My problem is that when I render the video the mouths do not reflect what is shown during editing... While I am editing I can ram render a small portion and the mouths will line up as I intend but once I do a final rendering they are slightly off at times... What am I doing wrong here?
The screen shot shows that I am in my 'Mouths, LG' pre-comp and the cursor is situated to show "layer 23" in the "Mouths, LG pre-comp"... Now the preview window is showing one mouth for layer 23 (the wrong mouth) and when I open layer 23 you can see that a different mouth is shown towards the top left side of my attached image. I believe whatever is causing this is the problem but I don't know how to make it right.
I'm running windows 7 64bit if that matters and I am running After Effects CS6 Version 11.0.2.12
Any help would be greatly appreciated.

Are you nesting your Mouths comp in a main comp, enabling Time Remapping on that nested Mouths precomp and then animating? I can't tell from your screen shots.
And BEFORE nesting it, I'd also make that Mouths comp 1 frame shorter to eliminate that one empty frame at the end.
Nothing like instructions in the wrong sequence, right?

How to activate Time Remapping ? (CS5)

Hi.
I try to activate time remapping on a Layer, without success.
I tried AEGP_SetLayerFlag without.
I tried the Do_Command hint from here http://forums.adobe.com/message/1799231#1799231 nothing worked.
Here's my portion of code :

i don't know why the AEGPDoCommand fails to deliver for you.
you can however use AEGP_ExecuteScript() and use java from within your plug-in to enable the time remapping.
here is a thread that shows the complete process of using AEGP_ExecuteScript:

it actually goes into more trouble than you need.
a simple AEGP_ExecuteScript("simplest java code to enable time remapping") will do the trick.

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.

AE CC: Time-Remapping Glitch

This was a problem in AE CS6 that I have complained about before. It is not nearly as bad in AE CC, but it's still there. Unfortunately it can be difficult to replicate with consistency. It may have something to do with the conversions between "time" and "frames".
The problem occurs when you have a sequence of layers (each layer taking up a single frame) that is precomped.
For example, this expression can cause problems:
thisComp.layer("frame controller").effect("Slider Control")("Slider").value*source.frameDuration;
This is abstracting the time-remapping to another layer with a Slider Control. It then takes the slider value (which represents frames) and converts it to a 'time' value. I have found this to cause unpredictable results in CS6 and CC. Sometimes it shows the correct frame, sometimes it doesn't.
However, if I modify the expression as such:
thisComp.layer("frame controller").effect("Slider Control")("Slider").value*source.frameDuration + source.frameDuration*.5;
The result is always the same, and correct. Here I am telling it to look at the 'middle' of the frame, rather than the 'start' of the frame.
I hope this is helpful in some way. I wish Adobe would fix this.
I will remind you that this problem has never occured in all previous versions I have used. I am fairly confident it is related to the new image caching system introduced in CS6.

Sorry guys, I think I have done a poor job explaining this bug. It has nothing to do with lip sync, or expressions.
Mylenium seems to express some knowledge of the problem - that being the image caching feature introduced in CS6. I did notice *less* of these problems with CC. So it means that Adobe is aware of it and trying to fix it. But I think something remains unstable in there.
When I considered the upgrade to CS6, I did a number of tests -- rendering out lots of our old work, to see if anything didn't render correctly. And wow, was that something. Most renders showed some kind of glitch -- all in our layer sequences (eyes, eyebrows, mouths, anything time-remapped basically).
With CC, I did the same test, and the renders were all perfect, as they were in CS5.5. So I figured they must have fixed the problem, and they did to a large extent.
But now after using CC for a few weeks, I am seeing these problems crop up again.
AE has no problem with 'image sequences', that is, a series of still images files, which are treated by AE as actual footage. It seems to have issue with the sequencing of layers in a sequence, that is taking 20 layers, and using Keyframe Assistant - Sequence Layers. I think this is because of the way AE treats Comps differently from Footage. Footage is composed of discrete frames, with nothing inbetween each frame. Comps however are treated with floating-point time. Which is great when you *want* to 'slow down' a Comp, because it can do so smoothly. But when that Comp contains a layer sequence, I think this floating-point time makes AE confused, because the Comp doesn't contain nice, infinitely-scalable interpolated keyframe animation, but instead discrete pieces of artwork with no interpolation possible. My solution to this problem -- and it works -- is to add a 'half-frame' to the calcuation. This I think reduces the likelyhood of incorrect math going on with the image cache, because it's less likely to 'round down' to the previous frame.

Timewarp / time remapping not running smoothly?

Hi, I've got a problem with speed variation. I got 25fps exr footage rendered out of 3ds max which I want to add some speed variation to it in AE. The problem I'm facing is the footage stutters when using time remapping. basically what I was trying to do was to render the scene out very slow so I can crank it up in AE. I've even tried different blending modes (pixel motion).
Here is what happens when trying to add some speed variation (when slowing it down to the footage initial speed)
1. time remapping causes stuttering.
2. while timewarp gives strange interpolation errors (looks like blurring error) speed goes like 100-->150-->100 and errors occurs when going back to 100
system:
windows 7 64bit, i7 2600k, 3,4GhZ, 16GB RAM, Geforce GTX 580
AE CS5.5

this 1 got timewarp ( and speed is cranked up, not slowed down)
thats the interpolation frame
that's without timewarp
time remapping brings same error but for RPF files looks like it works for EXR
looks like stuttering is not a problem anymore. i ran another random speed variation test and it'd run smooth. Have to double check it with the intended speed variation
I'll try to post a similar project where file size is smaller

Adobe After Effects CC Time Warp Issues

Anyone on here proficient in After Effects CC? I'm attempting to mess around with time warping to see if I can mimic the slow motion effects of a high frame rate camera, but the issue I'm running into is that when I slow down the footage at a certain point in the clip, it will slow down, but when it's back to real time speed the frames don't match up. And I haven't found a way to stretch out the length of the clip so the frames do match up. Any advice?

You need to read up on time remapping. For example: you have a 30 second clip shot at 30 fps and you want to play a clip at normal speed for the first 10 seconds, then, and heres the hard part to wrap your head around, slow down the next 10 seconds to 1/4 speed to simulate shooting the clip at 120 fps, then play the last 10 seconds at normal speed. The hard part to wrap your head around when you do this is that the middle 10 seconds will now take 40 seconds to playback.
Here's what you do:
Enable time remapping
Note that there are 2 keyframes, one at the first frame and one that is 1 frame past the end of the video (I won't explain why it is there but trust me it makes sense)
Move your CTI to the 10 second mark and set a new keyframe by clicking the diamond in the Keys column in the timeline
Move the CTI to the 20 second mark and set a new keyframe
Extend the length of the composition to one minute and ten seconds (this is some of the hard part to wrap your head around)
Move the CTI to the end of the extended composition and set a new out point for your video by pressing Alt/Option + ]
Now move the CTI to the one minute mark (one minute because the middle 10 seconds is now 40 seconds long so the end of the slow mo section will move from 20 seconds to 1 minute
Select the last two keyframes and drag them to the left until the keyframe originally set at 20 seconds snaps to the one minute mark and the last keyframe is one frame past the out point of the clip
That's all there is to it. Your new modified video plays at normal speed for the first 10 seconds, 1/4 speed for the next 40 seconds, then resumes normal speed. You can check out the speed graph to verify the speed change and even modify the curves so the change in speed is smoothed out, but if you do that you should have decided before you moved the last two keyframes and set two additional keyframes at san 10:10 and 19:20 to give you a few frames to ramp up and ramp down your slow mo.
The thought process is the same no matter what technique you use to change the speed in the middle of a clip. If you want to return to normal speed after the speed change you need to define the outpoint of the speed change and move the outpoint and the end point of the speed change down the timeline for slowing down a clip or up the timeline for speeding one up to return the clip to normal speed.
Now all you are stuck with is how to make the slow motion segment look smooth because you are repeating four frames at a time. Twitter is probably the best tool for this but it is expensive. AE's frame blending does a fairly good job on most video. Some video will not successfully slow down more than 1/4 speed no matter what software you use. Some video will slow down to 1/10 speed just fine using nothing more than Time Remapping. It all depends on the shot.

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.
