Stuttering when changing speed to 10%

I have a 16mm film shot at 16fps that I transferred to miniDV and then captured. I changed the speed of the clip in Final Cut Pro to 10%. I did this to get a slow motion effect. It looks great on the Canvas, and on some monitors, but when viewed on other monitors or from a DVD that was burned, there is a stuttering effect where agencent frames flicker back and forth every several frames. What can I do to fix this?

Wow, that's a lot of steps ...
There is also the more labor intensive (but much cheaper) slo-mo process using Compressor that Patrick Sheffield developed. Compressor uses the same optical flow technology as Shake so if access to Shake is not a possiblity and you need to do this NOW, it is listed below.
good luck.

As you may have noticed when you slow down footage in FCP and use smoothing, it goes a bit "soft". This is because in order to make the "in-between" frames it contructs an average of the previous and following frames. Compressor 2 actually does an analysis of the pixel movement and constructs an inbetween frame that is sort of the equivalent of motion tracking each pixel. This is the same kind of stuff that the Twixtor plugin does.
Here are the results: A still from my 75% slow-mo from Final Cut and from Compressor. Note the difference in detail...
In order to use Compressor, I had to do some monkey motion. I exported my clip from FCP as a self contained Quicktime. Because the video was shot on film and transfered with a 3:2 pulldown, I used Shake to remove the pulldown. You could also use Cinema Tools to do the same thing.
After that a little math is required. I wanted to run the footage at 75% or 3/4 speed. That means I need 4/3rds the number of frames. Multiply that by 24 fps (my original footage speed w/o pulldown) and I get 32 fps (if my footage had been at 30, I'd be using 40 fps).
Knowing that, I plugged my clip into Compressor 2, selected a codec (probably the same as you are feeding into it), set the frame rate to 32 (calculated above) in the codec options, selected the Frame Controls panel, turned Frame Controls to Custom - now here's the key: Set Rate Conversion to Best (High Quality motion compensated). I then saved this setting as 75% Slowdown for future use.
Submit the batch and wait a while. When it completed, I used Shake to set the frame rate to 24 and insert a pulldown, but again, you can use Cinema Tools to resolve the frame rate.
Brought that clip back into FCP and Voilá! Clean slowdown.
Have fun...

Ripple effect on timeline when changing speed

When I speed a clip up, all clips on my timeline after that clip get sucked back. If I slow a clip down, it will push all clips ahead of the slow clip forward on the time line. Is there a way to stop this from happening? Right now I just put the clip I want to edit the speed on a new video track and lock everything all other tracks. But is there something in the settings maybe that can make it so speed changes do not move any other clips on the time line?

Well, one way is to use the speed tool (sss)...
Just make sure the clips aren't touching (unless you want to change the speed of the clip butted up to it, and in that case it will have the opposite effect), then speed up the clip, then close the gap by extending the speed changed clip.
However, to slow it down, it may be a bit harder because you have to ensure you have empty spece or else the speed tool will just write over the next clip.

Music Stutters when changing tracks encoded using FLAC

When changing tracks encoded with FLAC, the song stutters a bit at the beginning of each song. The rest of the song continues to play fine. It's just at the beginning when changing tracks manually.
These very same tracks played fine with the previous firmware on the iPod and play fine on my MacBook now using iTunes.
Anyone else running into the same thing?? Everything works, but its rather annoying!!!

MPD is VERY touchy when I change the current playing track, or seek.
I've been using ncmpcpp, but I witness the same behavior with other clients too.
Since I've seen other people mention the same stability issues, I was wondering if anyone came up with a solution for this ?
I was hoping to use mpd to build my music db, but I 'skim' through a lot of music, so it's not usable to me right now...
Will appreciate any help.

Try that link out and try setting it up via user in the alternate setup. I had issues it running as deamon... This way it will run as a local user and just add it to a start script when you start your .xinitrc or autostart.sh...

Error when changing speed

Hi,
I'm adding a studio produced audio track to a band's live performance. The timing isn't perfect so I'm cutting small sections of the video and slowing it down or speeding it up to keep it in sync. It was working great and I was almost done, but all of a sudden one of the sections is giving me a hard time. When I try to change the speed, it says the change can't be made because of an error. I can't figure out what is causing the error. I pulled the bit onto its own track temporarily to make sure it's not bumping into anything and it isn't linked to any audio. Does anyone have any ideas what might be causing the error all of a sudden?
Thanks.

Thanks to both of you. Anton's comment about the problem being in the rendered file made me decide to erase the 10 second clip and then lengthen the previous clip and re-cut it. Now it's all working.

I was listening to Audio Books on my iPod Touch in the car when the speed changed to fast forward on all the audio books. How do I correct this?

I was listening to Audio Books on my iPod Touch while on a motor trip when the speed of the playback suddenly changed to fast forward for all the stored audio books. How can I correct this?

Actually found this answer in the archives: When the audio book is playing, hold finger on middle of screen until the speed selection message appears and change from 2x to 1x. Thanks for your response though!

How to update the table when change list item in classic report

hi ,
i worked with apex 4.2 and i create normal classic report with one select list(named loved)Column ,now i want to update table when user change the list with new value ,i can't create dynamic action to do this,i create check box with primary key and loop for check item to update the table but i can't get the value of list item. and for more speed the user want to do this when change the list value.
my question
1- how to do this by javascript and get the value from list item and update the table with new value
2- is i must use API to create list item so i can get the value of item in report or what.
Thanks
Ahmed

I coded the following to give you direction:
1. In the "Element Attributes" section of the DEPTNO column, I call a javascript function as:
onchange = "javascript:updateTable(this);"2. I wrote a simple javascript function that shows an alert when the user changes the select list as:
<script language="JavaScript" type="text/javascript">
function updateTable(pThis)
var vRow = pThis.id.substr(pThis.id.indexOf('_')+1);
alert('Row# - '+ vRow + ' has the value - ' + pThis.value);
</script>Now, you can call a AJAX on-demand process inside the javascript function to update the database value.

Any way to change speed of a clip in "over-write edit" mode?

I want to change the speed of a clip in the timeline without having to lock all the other tracks or having to move the other following clips out of sync. For example I have a clip which lasts for 1 sec, which I want to change to 3 secs. Normally when I do this in the timeline the other clips on the same video tracks which follows, will move their position..... How to change speed in "over-write edit mode"?

I think it's even easier to just match frame the "source file"... put your playhead on the clip you want to speed change in your sequence. Then type optioncmdf. Perform the speed change in the Viewer, then simply cut it in... Might help to put it up above the older, use the double arrow selection tool facing right to move the clips past this change later... pull the upper track speed changed clip down over the old, and viola.
Gotta say though, it's a lot easier to perform the speed change in the Viewer, and edit it all in as you go rather than doing it after you've put the clip in a sequence. (not always possible to determine what the speed change should be maybe, but sure easier.... FCP 7 handles this problem a lot better for sure, and worth the upgrade price if your machine is compatible.

Problem Importing Sequence and Changing Speed

Got a good one. I imported 2 sequences into a new project, but when I try to change the speed to anything over 100%, the end of the clip is black. If I try cutting this part out, what happens is the black screen increases, chopping off more of the clip/sequence!!! I've tried everything, and I know it has to do with the sequence being imported, but is there a workaround for this?? I've even tried putting a title/image in another video track, and same thing happens - more black screen, that cuts off even more of the clip. Help please!!

4) clicking on "speed/duration", and changing the speed to, let's say "125%",
Ok, back to my question of post 1. Where exactly are you doing this? To the individual clips, or to the nested sequence?
I suspect the former, given the results. And this is perfectly normal. When you speed up the footage, it takes less time and creates a shorter sequence, but the nest doesn't automatically shrink to compensate, so the last bit of it will be black. It's no different than if you were to remove a couple of clips from the original sequence. All you need do is trim the nested sequence back to the last frame of footage.
Or you could make the speed changes first and then nest it afterwards. Then there would be no black. (And this is what you were seeing when you went back to the first project and changed it there. The end result was that the speed changed before you nested. The black only shows up when you shorten the original after nesting.)
So, bottom line, everything is working normally. You were just unaware of how it worked.

Best way to change speed of clips

Hey, I want to change speed of clips, both faster and slower in one clip. What is the best way to do that preserving the quality? I am still learning FCP so my apologies, and I had a hard time finding anything on here through search.

Jerry's right...
Take a look at this:
http://homepage.mac.com/captmench/SlowMo3.mov
Two frames each of FCP and Shake at 50%. Use your arrow keys to go frame by frame. First frame is normal, second is interpolated. Look at the background!!
Creative cow should have the whole tutorial online soon... I'll post back with the link when they do.
Also, for time remap -- shake's got that under control too... but for now, look at this:

Hanging when changing channels

I am currently on release 1.9 build 10.95. Ever since the software was "upgraded" I have noticed the following:
Intermittently, when changing channels, by selecting from the guide, often the system will hang, for up to a minute, before the channel finally changes, almost as if it is waiting for something to time out.
Intermittently, when I use the remote, the green light will flash on the box showing that a signal has been received, but nothing happens. I may have to issue the command two or three times.
This has happened on all three of our DVR's - Motorola QIP - 7216 1
I have reset the box via software, physically reset the box by pulling the power chord, and put new batteries into the remote, numerous times, and the problem persists.
Is it only me, or has this problem been reported under a different heading?

Usually, you can turn off a video setting and it speeds up the responce time of the set top box. Try hitting menu - settings - video settings - sd override and selecting off. There are other settings in there but they dont seem to affect the responce time much.

Way to change speed of entire Project easily?

Hi, I know how to change the speed of an individual clip in the timeline - but is there an easy way to change the entire speed of the project? Thanks.

Hi, thanks guys - that worked - although it seems when I change the speed of the nested sequence and export it the quality is quite a bit worse (exporting it with the same settings) - seems to be a lot of jagged edges now. Is there something in the 'Change Speed' window that should be changed? I am creating a sequence and doubling the speed and another sequence exported with 4 times the speed. What is checked in the Change Speed window is 'Frame Blending' and 'Scale Attributes' (the default settings). Any ideas how to get rid of the 'jaggedness' that is being created? (this file was originally a .dv file - a regular export to quicktime from regular speed sequence looks fine. Thanks.

Quickest way to change speed but not clip duration

I'm trying to determine the fastest method for changing the speed
of a clip already in the timeline, but not the clips duration. Primarily, slowing a clip down.
The best I've come up with so far is to put the timeline playhead over the
clip and hit X to get the clips IN and OUT points placed in the timeline. Then,
drag the clip into the Browser, effectively making a copy of it there. Then bring the clip into the Viewer, then hit APPLE J to bring up the speed change window, affect the change, then overwrite the change you've made in the viewer back down into the timeline where you placed the original IN and OUTS. Seems like alot of step.
Is there a faster way? Any change I try to make in the timeline itself results
in a clip duration change. The only other way I've found it to use the time remap tool put that is even more complicated and is alot less exact when trying to make something, say, 50% slower.
Any input would be appreciated.

Another, close but not quite there method I've tried is the TIME REMAP tool
that lives with the SLIP AND SLIDE.
I can affect speed changes, and see what percentage speed change I'm
trying to make, but it wants to change speed on both the left and right side
of the clip. In other words, I can't place the timeline playhead or Time remap tool at the beginning or end of the clip and only effect the speed of the entire
clip unless there is no clip adjacent to the clip I'm trying to change.
Otherwise it changes the speed as I want for 99% of the clip and then during
the last several frames I've accidentally sped up up those frames. I can't position it to just change the speed for the entire clip.

Changing Speed of clip in timeline in a specific wqay

I realize there are a variety of ways of affecting
a change to the speed of a clip already in the timeline,
but I'm trying to figure out how to do it in one very specific way:
If I have 3 clips (A,B,C) and I want to change the speed
of B so that it is slower, but not expand the clip from
it's original length (meaning it will still occupy the
same spot, duration and length in the timeline), is there a way of accomplishing that just by punching a specific figure
in somewhere (i.e. make it move at 50%).
I know about fit-to-fill, time remap, right clicking a clip
and changing speed. However, I don't want the clip to
expand past it's spot in the timeline, just play slower in the spot it occupies.
The closest I've come is going into the time remap tool and lowering the end keyframe so it moves slower, but this is
imprecise. I want to be able to punch in 50%, or 60% somewhere and have it take, without expanding. The time remap tool won't let me punch in 50%, although that indicator moves when I drop the ending keyframe down a little.
Can what I'm describing be done, and if so, how? Thanks.

Match frame back to the original media. Slow it down, then cut it back in.
You cannot slow down the clip in the timeline without it expanding. You are telling FCP to take the existing clip and make it longer...of course it will expand in size. It doesn't know that you don't want it to do that. It assumes (rightly so) that you want the clip, with the IN and OUT points you designated, to be slower. Keeping it in the same spot on the timeline means cutting off the head or tail of the clip...losing points you told FCP you wanted.
Simple to just load the clip into the viewer, slow it down to the speed you want, then cut it in.

Movie edited in Quicktime now stutters when streamed.

sorry haven't tried it when it is synced.
i recorded a TV show on a MigliaTV Max DVR... H.264/"AppleTV" format. This original movie plays back perfectly streamed to appleTV. Wanted to cut out commercials so i opened and edited it, chopping out sections of it in Quicktime. export as MPEG4.. i did passthru for audio and video.. but this movie now stutters when streamed... saving the movie as .MOV likewise stutters?
any ideas?

i did create a new file with the changes... that's how i know there is a difference.. the original works fine with not stuttering, but the edited file stutters... i did a total of 4 different files and all the edited ones stutter.
*Work Flow*
i just opened the file in quicktime, move the head to the location of the portion i wish to remove.. move the start and end thingys to select the portion i want to remove, press delete, repeat 'til all portions are removed.
don't have quicktime in front of me, but i think it's export.. save, saves as .MOV which stutters as well (tried that). export opens a dialog window.. chose MPEG4 in the combo box at the bottom of the window.. went to options and again don't have quicktime in front of me but they have an option for passthru for video and for audio chose that in both cases (could passthru be the problem? i've used it for audio before with no problem but not video).. change name.. export.
