Cs4: Time warp effect - black playback problem

I use premiere cs4. When i drag clip into time line (1440 25i mpeg transcoded from avchd 1080 50i) onto time line and apply time warp effect and after rendering clip is black during playback, simply nothing in it just black picture with the same duration as original footage.
core2duo 2,0 2mb cache
2 gb ram ddr
nvidia geforce 8400m gs 128mb cuda drivers installed. ( do premiere cs4 use cuda drivers?)
vista 32 bit
what 's wrong? what to do?
please

Hi!
No, the first frame is not black.. The screenshots where just examples and I tried to adjust the settings, because the first time I tried the timewarp it worked, but the next clip I wanted to warp just got black.. and I tried alot of times to figur out if I adjusted some of the settings.. ( I hope you mean the method and adjust time).
Those comes adjusted in pixel motion and Speed and thats what I have them on now.. Should I adjust it to something else?

Time Warp Effects in Premiere Pro CS6

Enabled Time Warp Effects in Premiere CS6: Ctrl+F12, TimeWarpFilterEnabled > true.
http://translate.google.ru/translate?sl=ru&tl=en&js=n&prev=_t&hl=ru&ie=UTF-8&eotf=1&u=http %3A%2F%2Fwww.efxi.ru%2Fmore%2Fpremiere_pro_cs6_time_warp.html

Works on my Android Nexus 7.
Anyway, here it is:
Turning Time Warp effect
Consider the example of the inclusion of qualitative change speed with the aid of the Time Warp (creating the effect of "stretching" the time or time warp) in the program Adobe Premiere Pro CS6. As we all know by default, this effect has been disabled in the version of Adobe Premiere Pro CS5, but you can turn it on. Press the keyboard shortcut: Ctrl + F12 and panel Console, switches to Debug Database View:
Paragraph TimeWarpFilterEnabled instead of trying to drive a false true. Restarting the program Adobe Premiere Pro CS6.

Will the Time Warp effect be eventually included back?

Dear anybody on behalf of Adobe Systems Inc.,
would you be so kind to give a clear answer if the Time Warp effect will be included into Premiere Pro back?
I've just started Premiere Pro CS5 exploration and realise that it's TOO early to switch to. And one of the reason is the Time Warp effect abscence...
I rummaged plenty of Internet pages but was unable to find unambiguous answer 'Yes' or 'No'...
Changing just clip speed gives quite a poor result (first and foremost I mean a movie look).
Discussions about product advantages in general have little sense if it doesn't provide high quality output.
No one of viewers is interested in if I was enjoying with a software while I was composing unprofessional looking film...
Thanks forward

That's not a good assumption.
Well, let's have a look at the form itself: http://https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform
It says (quote):

We normally do not send personal replies to feature requests or bug reports.
Having read those words, I should assume I would obviously get the answer on my question, won't it?
ON BALANCE (too many mere words have already been said...).
The Time Warp effect will NEVER be included back into Premiere Pro - it was deliberate marketing decision to exclude it.
Thanks for your time

Effects causing playback problems in Quicktime Player

My sequence is AIC 720 24p and plays fine in the timeline with affects applied. These are simple effects, like Fading and Cross Dissolve. When i export the timline without Quicktime Conversion but as a self-contained .mov file and try to play it back in the Quicktime Player, wherever an effect starts (from the timeline), the player freezes. The only way to get it playing again is to pause it, find where it skipped and go to just after the stopping point to play again. Is there some export setting I'm missing?
strangely, if I do an export from Quicktime to a new file (not just a "save as") the problem vanishes. the same can be said for exporting with Quicktime Conversion from the FC timeline. I'm trying to get this thing to a file without having to re-compress it several times. Can this be accomplished without exporting with Quicktime Conversion with an uncompressed codec to save the quality?
also: I'm running the newest version of FC Studio and the latest version of the Quicktime Player.
Thanks

Are you saving the file to a disk other than your startup disk? if not, that could be the problem. I think I'd render it all first, select file/export/QT movie... then use current settings and check on the "make self contained" option. This will result in a perfect copy of the original media files, and is as good as you can make. But it will take a pretty fast disk to play it.

How to minimise motion artefacts in the time warp effect?

Iv'e got a scene in disco where the subjects move quite quickly. How can I minimise the motion artefacts? What are the best settings? It looks sometimes quite 'digital' as if filtered with a median filter and sometimes there are ripple-like structures on the faces as if processed with wavelets.

I've experimented for a while now and setting the error threshold to 10 (from 1) and the motion detail to 5 makes it look pretty good. The error threshold essentially decides when to switch to frame blending instead of motion estimation. With a motion detail of 5 the motion vectors are quite coarse and the hopping looks natural. Hope that saves somebody else's time!

More weirdness from the CS3 time warp

I've applied the Time Warp effect at 50% to several adjacent clips in a timeline which works fine in all of them save two. In those clips the motion is jerky because if you scroll slowly ahead it plays a frame, then goes backward a bit, then what appears to be a full frame ahead, then back a bit. This repeats for the duration of the clip.
I tried copying the effect from a good sequence and applying it to the faulty one, thinking I may have an errant parameter in the bad one somewhere. No soap. It's still wrong. So I import the footage that has the problem into a new project and apply the time warp effect. No problem.
Back to the original project. I check the field dominance... not modified, and I check "Speed/Duration" which is set to 100% as it should be. Completely befuddled, I delete the Time Warp from the two offending clips, change the Speed to 50% and re-trim. It's all good.
What really confuses me is why this happened. Has anyone else seen this? If so, is there a way to fix it, or is it just another Time Warp bug? (I've already found one.)
System is:
3.0 GHz Dual Core Athlon
3 GB RAM
Windows Vista
HW and SW up to date
I don't mean for this to sound like a rant on the TW, but I'm trying to find out if others have seen this or if it's only my own ineptitude. If I were a betting man I'd put money on the latter.
Thanks.

Yeah I've seen it and what I do is get out of the program and then re-open it and it seems to correct itself. It has been an infrequent problem.

Time Warp issue CS4

I noticed that whenever applying the Time Warp effect to an MPEG clip, the clip goes black and becomes unusable. Tried this in old as well as new projects.
However when applying Timewarp in AE, to the same clips, the effect is fine...
Has anyone experienced this?

I experienced same "black video" bug with time related plugins liks "Sapphire FreezeFrame"...I think this bug is a result of plugins way of getting frames form original video for processing.
And here's a quick solution, till an update for Premiere Pro CS4 will be released:
b Right Click on the clip (at the timeline) that you want to apply your time based effect. And choose "Nest" from opened Right Click Menu... So you will have a nested sequence with your clip. Now you can apply your time based effect (timewarp, twixtor, freeze frame e.t.c.) to this nested sequence.
It works for me without any problem. I hope it will work for you too, tomst and DenisVID.

Unusual Time Warp issue in CS4 (4.1.0)

Two problems I am having:
1. When I add time warp to my clip or nested sequence, the preview clip suddenly appears to be scaled larger if the clip is sitting within a higher resolution sequence. The transformation is not dissimilar to having the "scale to frame size" option checked. The actual speed based time warp effect appears to work fine, so I can workaround this by simply applying this to the clip within a sequence that matches its resolution
2. Motion blur is not working at all...the default settings manual shutter control (shutter angle: 180, samples 5, pixel motion enabled) produces no blurring. I have processed this same file in After Effects CS4 and it works beautifully, but I wanted to try applying the effect directly to edited clips so that the blur effect does not span cuts as it does when I apply it to the entire file
Any ideas?

Purely a gues here, but 1 may be working as designed.
I have not used the Motion Blur effect yet.

Troubles with Time warp (CC) effect

Hello everybody,
I am experiencing some troubles when using the Time warp in After Effects CC. I would like to create a smooth slow motion effect in a video, but, even applying the Easy ease on the keyframes the effect produces some distortions in the images.
I don't know if it's important to say that the original images show two people dancing in a party and there are flashing lights all the time. Does this interfere in the result of the effect?
I've used this effect before in the its CS6 version and the result was excellent. I have already checked the graphics and changed some paramethers, but this doen't change the distortions...
Thank you

Some footage just does not slow down well. Here's what I would do. First, reset the time warp effect to normalize all the settings. Second, set the speed. Third, step through the footage one frame at a time until you find the frame with the most problems. It is here that you should start experimenting with things like block size, smoothness, filtering. When you get your best looking frame it is time to do a ram preview.
Some elements in the shot, like a hand moving for example, may require some roto or other techniques to create a matte layer. With some footage you will get a better result by simply using TimeRemapping with frame blending turned on. Sometimes Twixtor is the only solution. Twixtor has a lot more options than TimeWarp, but neither of them offer a one click solution to difficult shots with lots of edge detail.

Encoding and playback problem HD files

Hi all,
Currently, I'm using a new HD camcorder and have no problem with importing and playing these files is premiere cs4 pro. However, when I'm using six video track at the same time I experience some playback problems. After rendering, the video's play, but not smooth, they skip frames and playing a few frames back. In other words, it seems that the video playback stutters. The problem still excists when I encode the project to any file (mpeg2-blu ray, avi, etc). When using two video tracks (with two HD video) this problem is not present, even when these video's are in slowmotion. Installing the new update (4.2) did not solve the problem.
Specs of my system:
Quad core Q6600 @3.0GHz (overclocked)
8gb RAM
>200gb free disk space
windows 7, 64-bit
Does anyone have some suggestions to solve this problem? Thanks in advance.
Regards,
Jeffrey

Harm,
Sorry for not responing for a few days, but I runned the benchmark you'll send me. The main results (dee details attached file):
53,6, secs Total Benchmark Time
6,4, secs AVI Encoding Time
14,2, secs MPEG Elapsed Time
33, secs Rendering Time
Since the potential problem is my hard disk, inaddition, I runned HDtune (hopefully it will help pinpionting the problem):
disk1: avarage transfer rate: 94MB/s, acces time 13.8ms, burst rate 185MB/s
disk2: avarage transfer rate: 85MB/s, acces time 14ms, burst rate 157MB/s
disk3: avarage transfer rate: 73MB/s, acces time 13.9ms, burst rate 183MB/s
Analyzing these results, could the current hard disk configuration cause the problem I have, or is my system to slow anyway to edit AVCHD material?
If the hard disk configuration is the problem, could it be solved by applying your suggestion by removing all partitions? Since, I'm not looking forward of removing all partions(re-installing windows (dual boot win7 and vista), shifting a huge amount of data, etc), but if it would help I will do it.
Thanks inadvance,
Jeffrey

Time warp by source frame?

How do you use this?
I want a portion of a clip to extend to a certain time, I know I can use other methods than time warp. But, I want to try various settings that I see related to time warp. The documentation says adjust by source from is for setting a time where a frame is supposed to occur. Great. How do I do that? If I type a frame number into the source frame control, what is it doing? How do I specify that frame occur at a specific time?

I figured out how it works. I was confused because the frame is frozen on the keyframe and I hadn't added a keyframe at the end.
I did this:
Enable timewarp and adjust by source frame
Move to frame 0. enable animation. type the inpoint frame number from the footage and press enter.
Move to the frame to adjust. Type the frame it should be moved to and press enter.
Move to the end of the clip. Type the frame number that matches the end of the clip moved by the number of frames the 2nd keyframe was adjusted by.
Thanks. But, I am asking about time warp.
This seems close to giving the answer, because it at least uses source frames:
High quality retiming from 30 to 25 fps using After Effects
But, it involves changing fps. So, I am not able to think of how that would work for me, at the moment.
There are these things:
Frame to move 270
Frame at current desired position 247
Frame at start of selection 226
Maybe some of these are where you set a keyframe:
Keyframe at start
Keyframe at desired position
Keyframe at current position
When I select a clip to add to the composition and then select time warp from effects and select "Adjust time by source frame", the composition panel displays the first frame of the original footage.
The after effects help says that you can click the stopwatch to set a keyframe at "the current time" for that property value. Which current time?
If I click the stopwatch icon in effects controls for the source frame property, it stays selected. How do I indicate that I now want to go to a different location and set a keyframe?
If I knew how to set the keyframes, how would I tell it to now apply the time warp effect?
If I use the animation menu instead, there is an option to set a keyframe at the current source frame. Selecting that toggles the stopwatch icon, leaving me with the same questions.
If I click the triangle next to timewarp field in the composition window that lists clips, I can get at a diamond shaped icon to set key frames. I think I have set 3 keyframes at start, desired position for the end and the current position of the frame I want to occur at that position. Meanwhile the source frame property still says 226. If I scrub the composition windows displays that frame only...
I have no clue what I am supposed to do.
I missed this part of the documentation:
If you choose Source Frame for Adjust Time By, then you must animate the Source Frame property to do anything other than freeze on one frame.
But, so far, I haven't figured out how you animate the source frame. Whatever value I put in it is the frame that is frozen. I don't see how to then add another step in the animation.

An odd by-product of PP3 Time Warp FX

I was playing around with the Time Warp effect on a clip in a timeline and it wants to play the first 15 frames backward which just happens to be the length of the cross-dissolve. If I move the clip to another video track in the same location in the timeline and create the dissolve using the clip's opacity it works fine.
I'm wondering if I'm doing something wrong or this is just the way it works.
System is:
Dual core Athlon 3.0 MHz
3GB memory
MS Vista
All sw and hw updates are installed, including PP3

You're welcome. It's always a good thing to know the basics before moving on to the advanced stuff. Let us know how things go.
Happy editing.
Cheers

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.

After Effects Time Warp and reverse

Hi there;
I am a university student and stuck with a project, I normally use photoshop but I am working with short videos in after effects, what I am wanting to do is quite simple, but I am stuck with it.
I have some short clips (30-60 seconds) which I need to reduce in speed to roughly 1/4 - 1/16 speed. They were shot at 60fps, but I need the actually image frames so I cannot play back the footage slower. I also need to reverse the footage. This is what I am doing;
Import movie;
interpret footage;
     Loop;
     4.
New comp from footage;
Time Warp;
     Speed;
          25%
Which turns a 30 second clip into 2 minutes and adds lots of useful frames.
However, I need it to play backwards too, so I hit CTRL, ALT, R (Time reverse layer) and all the footage turns into a single stuck frame!
So I undo that and set time warp speed to -25% - same problem, what is going on? How can I both reverse the footage, AND timewarp it?
I have very little experience in AE, I am normally a photographer
Also, is there a way to export EVERY SINGLE FRAME as .png or targa? Technician has told me that this is "impossible" but then a friend has said that it is possible to export Tiffs from some software? I know that 2 mins at 60fps 720p will be roughly 20Gb of files - just trying to save a software step?

Pre-compose before you reverse.
Setup the render cue and output module to output an image sequence. This is basic rendering knowledge covered in the help files.

Bridge CS4 - MP4 preview playback problem

In Bridge CS4 on Windows, the preview playback of MP4 files sometimes works and sometimes it does not. If not, Bridge shows only an icon in the preview pane and there is no preview start button.
I have sets of MP4 footage that work OK, but other sets can only partly be previewed. Another strange behavior of Bridge is that in some cases after changing the file's name, the program suddenly does not show the preview anymore.
Is there anyone else having the same problems?
Arman

Read this thread, especially post #19 and see if it solves your problem. http://forums.adobe.com/thread/652660?tstart=0
All MPEG files are not the same so just becasue one play does not mean they all play.
If changed files do not show up purge the cache (tools/cache/purge cache) and let it rebuild.
