Seeking frames between keyframes

For several years I've used ffmpeg to generate (local) mp4
for football coaching videos. I'm trying to move it all to the web
so want to generate use flash/h264 for this purpose. Currently I'm
using apple's quicktime plugin as it is clever enough to allow one
to 'backstep' one frame at a time by (I assume) generating
intermediate a frame if necessary for display. Can anyone point me
to information to get me started on this? Thanks.

I think the OP doesn't mean empty keyframes (s)he just means to add frames. On my machine, at least, F5 just adds more frames, not an empty keyframe. So the flickering shouldn't be a concern here....
If you are just getting into code tweening I would suggest looking into the TweenLite/Max classes from Green Sock instead of the built in ones.
And Ned is correct, JSFL can automate many mundane tasks that you might perform in the authoring environment. I've only dabbled with it a bit, but it could easily do what you are asking. There might even already be some script out there that adds a certain number for frames at each keyframe in a layer or a timeline or some such.

  • Automatically add clear frames between keyframes?

    I have several movie symbols with a different bitmap in each keyframe. Since they move too fast to match the other symbols, I want to put clear frames between each keyframe. So far I have just been clicking each keyframe and hitting F5 several times but I thought there might be a better option.
    Is there a way to automatically add a number of frames between each keyframe?
    Thanks

  • I need to double my frames between my keyframes....

    I am working in the timeline and I have a shape tween keyframe at every 200 frames running for about 8000 frames (its an abstract geometric artwork)
    I want to double the frames so there are 400 frames between each keyframe. I can go in and do it manually but does anyone know if there is a faster option?
    Thanks.

    you can halve your framerate.  that will have the about the same effect as doubling the frames but will effect all your timelines so may not be satisfactory.
    try it and see.  it's easy to undo and quick to do/undo.

  • Dent/dip in motion graph between keyframes

    I've noticed that ever since upgrading to AE7, I occasionally get this strange dip/dent in the line/curve between keyframes that I can't seem to get rid of.
    Commonly, it occurs like this:
    I set a keyframe at the first frame, then move the layer/item and set another keyframe at (say) frame 30. Everything's fine... Then I move to (say) frame 40, move the item, and set a keyframe. When I look at the graph, rather than the usual line going from one keyframe to the other, I have a kink/dent in the line going from keyframe 2 and 3, as if a keyframe of a different value was place in between the two keyframes.
    I've tried toggling linear/bezier interpolation, and even removed and redid each of the keyframes, yet nothing gets rid of the kink.
    Has anyone else experienced this, and does anyone know why this is happening? This has prevented me from finishing even simple animations, because there doesn't seem to be any way to fix it.
    I never had this problem with previous versions, so I'm really puzzled by what is causing this. Just 3 keyframes, and it does it... nothing else complex or unusual.

    I think what you're talking about is bounce or rebound. If you change the spatial interpolation from bezier or auto bezier to linear the bounce will go away. You can't change spatial interpolation directly in the timeline graph editor. You change it by going to Keyframe Interpolation by right clicking (or Control + click on a one button mouse mac) on your selected keyframes in the timeline window and picking Keyframe Interpolation or by using the keyboard shortcut Ctrl/Cmnd + Alt/Option + K, or by going to Animation>Keyframe Interpolation from the menu bar.
    While the graph editor will give you an indication of the position of the layer, you can only manipulate the time values in the Timeline Window. In the Composition window, you can only adjust the spatial (position, rotation) property. If you look closely at the keyframes in the Composition window before you change spatial interpolation, you'll see bezier handles on the path. They are really difficult to see on a straight path, but they are there. Changing Spatial Interpolation to linear will get rid of these handles, but you can also do it manually by holding down the G key while hovering close to the motion path and when the cursor changes to an open arrow you grab the path bezier handle and drag it to the keyframe.
    Hope this helps. It's a rather common problem that's easily solved once you realize that you're adjusting the when in the timeline and the where in the comp window.

  • How to apply saturation filter between keyframes only?

    Hi,
    I have a bunch of old home videos that look bleached, I mean flat colours. It's the camera that causes this (it's a cheap camera). So I found a filter in Premiere that I can use to adjust saturation:
    * Fast Color Corrector
    Now I can only apply this filter to the entire clip. However, some parts of the clip need different settings than others, so I tried to use key frames but that's not going to fly with this filter. It makes sense because it's called "Fast Color Corrector". However, I haven't found a filter that allows me to adjust saturation for individual parts of the clip between key frames.
    Where should I look?
    Thanks.

    If the other two suggestions do not help you, rather than apply between Keyframes, you can also cut the Clip (Razor Tool) and apply where needed. If you need the "ramping" effect of the Fast Color Corrector, then just add a Cross-Dissolve. This works for other non-Keyframable Effects in many cases.
    Good luck,
    Hunt
    [Edit] You might want to Alt-click the Video to unlink it from your Audio, when using the Razor Tool. No sense in cutting your Audio too - in a very few instances, this can cause little "pops" in the Audio.

  • Multithreaded Video Decoding and Seek frame accuracy for seamless m4a loop

    Hi everybody,
    We read that flash 11.2 and Air 3.2 will improve the seek functionality.
    Right now being able to select a part of a track and precisely loop it is very difficult and complex for an mp3 but impossible with an m4a due to NetStream.
    So if you could let us know if the Multithreaded Video Decoding and Seek frame accuracy improvement in 11.2 and 3.2 will bring us a solution would be great!
    Basically as m4a are local files does 11.2 and 3.2 will allow to seek not only to keyframes but anyframe? This is key functionality to all music applications. If not do you think it will come soon?
    Thank You

    Seamless looping using seek will not work very well. It will have to be a separate feature.
    You could submit it as a feature request.

  • FCPX, Phantom floating between keyframes.

    Hi,
    I have been a fan on FCPX but I have to say now I am using it to make simple animations on a tight deadline it is REALLY stressing me out. Ok so there is a glitch I cannot fix and here is an example.
    (it does not matter fs this is on Text, and image or anything else)
    So I may want to make a bit of text shoot out of frame to the right, this is what happens (in this example say the text is 104 frames long)
    Key frame A (at say frame 0) possition full left of screen
    Key frame B (at say frame 100)possition still at full left of screen nothing has changed.
    Key rame C ( at frame 104) possition off screen all the way to the right.
    Ok now here is where the problem is and please note for this to happen I dont even have to make keyframe C..... So now between keyframes A&B the text will float the the right and then float back to the left but there are no keyframes or anything else telling it to move.
    WHAT IS GOING ON???
    This has been happing everytime I try to animate anything and I have no answers, put two key frames down with no changes and the element will just float around between those keyframes for no  reason.
    Any help apreciateds.
    Thank
    Robin

    I was seeing this yesterday. Its to do with how FCPX is interpolating the data between the two keyframes. In this case it thinks it wants to ease in and out from the two values, even though the values are the same, this is why you get the spurious motion between the two keyframes. In Motion you would simply bring uo the keyframe editor and set the interpoltion to linear. I couldnt find a way to do this in FCPX.
    The way round it in this case was to get rid of the last keyframe so it stopped all the stupid unwatned movement. Then blade the clip in half and then animate the second clip as needed. Drove me crazy for a bit.

  • Weird movement between keyframes? (not boomerang)

    I'm using CS3 and I'm getting some wierd movement occasionally between keyframes in "position" and it's not the boomerang effect. The frames aren't identical, but the z position SHOULD be the same and not change (the x and/or y do). I've looked at every angle I can find and used the graph editor and can't figure it out. In the preview screen I can't see the movement in the path but when I use the graph editor and use the value view I can see the odd random jerky movement in the z line. It's almost like a wiggle (which I've never actually used) and not a smooth continuous motion like the boomerang effect. :-/
    I can't find anything on google about it, although I might just not know the write phrasing. Does anyone know what might be causing this??? It's driving me crazy!

    Without screenshots, system info and details about your project nobody can know. That said, quite often AE's crappy graph editor will draw jittery lines when zoomed in due to how it iteratively quantizes the curve drawing and there is actually nothing going on. So unless this is an issue with final rendering, I wouldn't go crazy over it.

  • Getting blank frames between clips

    I have various clips on the timeline snapped right up against each other yet I'm still gettting a black frame between adjacent clips. There's no keyframes or opacity adjsutments on any of the clips so I don't know what's causing this.
    This clips themselves are edited so that there's nothing extra on the beginning or end of them that would cause this issue. Anyone have any suggestions?
    Thanks,
    Ray

    Just a thought ... I had something similar happened when I did not have snapping enabled but positioned a clip perfectly on the end of a preceding clip.  I thought everything would be fine, but it was not.  My clue was that a dissolve was not taking when I tried to apply it.  I looked closely, but the two clips seemed perfectly matched.  Then I tried something new ... After making sure snapping was enabled, I then moved the clip to the right enough to let the snapping bring it back together with the preceding clip.  To my surprise it solved the problem for me. The dissolve then "took".   I really don't like having to find "work-arounds" for things like this, but some bugs on little things like this can be expected on a 1.0 release.  In the meantime, overall, I am very happy with X and am getting a lot of projects done much faster than before.  Hope this helps.

  • Adjust audio levels between keyframes

    Hello,
    What is the shortcut to adjust audio levels between keyframes (in sequence)? I know the shortcut CTRL ] [ , but this shortcut adjust audio level for entire audio.
    I also know I can drag up and down the levels between keyframes using mouse. But some months ago I saw a tip ( from Steve martin) showing
    how to adjust audio levels between keyframes using a shortcut..and better,in RT. but I forgot what is the shortcut.
    thx

    there is no shortcut command for this in FCP, you need to use the mouse to drag the audio level up or down
    perhaps its another application your thinking of?

  • Why does my image 'float around' between keyframes?

    Why does my image 'float around' between keyframes when I'm transforming it? I want it to stay still for a period of time before I make it move again but it kinda floats around even though I didn't ask it to. Help! And thanks!

    You have to set the keyframe interpolation to "linear".
    Control-click on the little icons along the path in the viewer to make that change.

  • No jumbo frames between 4500-X and Force10

    Hi,
    We have just installed new Cisco 4500-X 10Gbe SFP+ switches.
    We have Dell Blade Chasis with Force 10 MXL blade switches.
    We are testing/preparing the environment before our new Dell compellent hybrid arrays arrive, but we face a problem with Jumbo frames between the Cisco 4500-X and the Dell Force10.
    When I do a ping -L from the blade server to a host connected to the Cisco 4500-X anything bigger then 1472 bytes seems to get dropped.
    When performing a ping between servers connected to the 4500-X I can use jumbo frame sizes like 9000 without issues
    When performing a ping between servers in the blade chassis I can use jumbo frame sizes like 9000 without issues
    Now we also have a pair of Cisco 3750X switches that are currently being used for Dell Equallogic 1Gbe SAN and they are connected to the same Force10 switches as the 4500-X are and I have created the exact same LACP port-channels between the Force10/3750X as for the Force10 4500-X. Jumbo packets to the 3750X is working fine but for the 4500-X it is not.
    I have tried connecting the switches simply on access port level, creat a vlan trunk and create a portchannel with trunking but none of the solutions seem to work, in every situation packets above 1472 are dropped... at least they dont arrive at the destination.
    On every port of the 4500-X the MTU is set to 9198, the vlan each port is in is set to 9198 and the port-channel is set to 9198
    System MTU can only be set to 1550 so that is on default 1500 altough I tried setting it to 1550 but that didnt make any difference ofcourse.
    The 4500-X is running version 03.04.04 SG / 15.0(1sr) SG10
    The Force10 is running 9.6.0.0
    Any help is appriciated

    Sorry for the delay , i have bought the 3064-32T , it seemed more cost effective as the transceivers are so expensive and it has more ports too.

  • Pixels appear every 1 frame between 13 frames last about 15 sec

    I got master which is HD 1920 x 1080 prores then convert it to 720 x 480 widescreen then compressing it to m2v. Notice pixels appear every 1 frame between 13 frames last about 15 sec on m2v. Why is that? Is there other compressor program than apple compressor. I use Compressor 3.5.3.

    YOu don't need to do that first compression. Just take your HD output into Compressor and use the DVD presets.  Your method is adding a compression step that is unnecessary, and might be the cause of those issues.

  • Inserting Keyframes Between Keyframes

    OK this is what I'm trying to achieve. Basically I'm doing some animations in AE on some pixelation. what i want to do is place the first keyframe and then move the position or whatever (scale/rotation) and then INSERT a keyframe every 2 frames in between these. Basically I want to then Hold these keyframes to make it look like it's not "tweened". Kinda like when you use the "exponential scale" option on something. Now I can do it frame by frame but I was hoping someone might have a nice, quick and easy solution and save me all this hassle this holiday season.
    Ed

    Well, the expression does put the animation on 2's (or 3's, or whatever number of frames you designate in the first line), but it doesn't do so using keyframes. Rather, it does so by modifying the output value of the property. This has the advantage of allowing you to change the keyframe values, change the keyframe interpolation, or even move them around on the timeline, without having to generate new intermediate keyframes.
    However, if you want to be able to mix and match different step values on the same property, the expression as written isn't able to do that. I took a crack at implementing the ability to set the step using marker comments tonight. I haven't really thoroughly tested it, so let me know if you run into any bugs:
    stepFrames = 1;
    prevKey = nearestKey(time);
    if((prevKey.time > time) && (prevKey.index > 1)) prevKey = key(prevKey.index - 1);
    baseTime = prevKey.time;
    if(marker.numKeys > 0){
    for(i = marker.nearestKey(time).index;
    i > 0 &&
    (marker.key(i).time > time ||
    parseInt(marker.key(i).comment) != (marker.key(i).comment - 0)); i--);
    if(i > 0){
    markerValue = parseInt(marker.key(i).comment);
    if(markerValue > 0){
    prevMarker = marker.key(i);
    stepFrames = markerValue;
    baseTime = Math.max(baseTime, prevMarker.time);
    step = thisComp.frameDuration*stepFrames;
    valueAtTime(baseTime+Math.floor((time-baseTime)/step)*step)
    If you apply this expression to a property that has keyframes applied to it, then place a layer marker at the point on the layer where you want it to be on 2's, and put the number "2" in the marker's comment field, the animation after that point will be on 2's. When you want the animation to go back to 1's, place a layer marker with the comment "1" at the point where you want the 1's to start. This should work for any nonzero integer ("0" will be treated as if it was "1"), and markers without a comment should be ignored.
    Again, I haven't really stress-tested this, so there might be some special cases I haven't accounted for.
    Update: For some reason when I copy the expression back into AE from the forum webpage, it looks fine when pasted, but when I hit Enter, the expression changes such that all the carriage returns are replaced by double question-marks. Pasting it into TextEdit, where it looks perfectly fine, then copying it into AE yields the same result.

  • Seek on FLVPlayer / keyframes

    Hi,
    for fast forward and backward I use the seek command of the FLVPlayer and add or substract one second to the playheadtime. I tested this on two videos. For one it looks ok but the other one just jumps back when playing forward. I guess this might be because of fewer keyframes.
    Is there a way to just jump to the next keyframe of the video? Or how would I do this better?
    Thanks in advance!

    As far as I know the seek will simply use the keyframes present in the video - and if there aren't enough of them you'll get really bad fast forward or rewind, or it may not work at all. The only remedy is to re-encode the video and use more keyframes - I always use the manual setting, and add keyframes every 15 frames.
