Jerky Motion and Slowness

Intersting--I find that on many Aps and even on Mission Control, Lion doesn't seem to run smoothly. Anyone else experiencing this?

Yes, I am having a similar problem with Lion. Scrolling does not work well. I have loaded it only on my macbook Air, with 2 gb ram. Is more required?

Jerky Motion on TV

Hi
I'm shooting HDV on a Canon HV20. Exporting finished sequence as QuickTime movie using AIC works fine - plays perfectly full-screen on this Mac. Burning to DVD using iDVD for widescreen PAL playback produces very jerky motion and panning. Any ideas why this might be? Camera set on auto for all this material.

Hi Falco,
the problem you are experiencing is a known bug of the 6.1.3 firmware version.
What you need to do is to download the latest firware version following this link

Imovie shakes on Slow motion and transitions

Hi everyone, hope someone can help me.
I recently went to a wedding and my mum video'd it. As part of the present for the bride and groom I wanted to get a nice song and put snippets of their day into a small video. I have used either cross-disolve or the other one (overwrite or something its called) in between the clips and I have also slowed one of the clips down to make it look like slow motion. On the computer this was fine and then I put it onto DVD and when I played it through the DVD the transitions and slow motion are really jerky as if its shaking. It doesnt do it all the way through, its really just at the beginning of the DVD and then it settles and the last 30 seconds or so are wonderful. Can anyone advise as to what to do?
Thanking you in advance
Tracey

I finished a video on whale watching, I retimed some of the clips to run slower to reduce boat motion and added a few whale sound effects, when trying to send to media browser or compressor I keep getting Frame 3085 (error-1) please help

Trash your preferences. Trash your project render files. Switch off background rendering. Do not render. Export.

HVX200 and slow motion

Hi,
Despite having read several how-to articles, I am still a little unclear on how to make best use of the HVX200's variable rate feature.
What I have done successfully is the slow motion feature that's described here:
http://www.studiodaily.com/studiomonthly/tutorials/trainup/5993.html
First of all, is that generally considered the correct setup?
If so, what's the best way to handle something that I might want at normal and slow motion? For example, a skating coming towards the ramp should be at a normal frame rate but on the jump, I want to use slow motion. Would I shoot all of it at the faster rate described above, use that directly in the 24p timeline for the slow motion part and convert the rest the clip to 24p? That is what I assume, based on reading this
section of article on the History Channel shoot:
O’Brien added, “The most useful feature of the camera was its ability to shoot 24 or 60 frames for any particular shot. Having 60 frames to use as a slow motion shot in a 24 frame timeline was the closest I've come to the days of 16mm, where you could dial up to 72 frames for slow motion. The 60-fps shots can be easily converted in Final Cut Pro to 24-fps if we decide not to use the shot as slow motion. Knowing this, we were unafraid and shot anything that we might want to be slow motion at 60 frames. This gave us a freedom we would not have had on film, where a slow motion shot would be expensive to convert back to normal.
Just writing this down is making me think more clearly that this is the best path but opinions would be much appreciated.

fh

Hello and welcome to the forum.
You adjust speed in the Modify menu. Select Modify>Speed or press Command/J.

Why is my new iPad mini with retina very, very jerky and slow?

Hi,
Does anyone know what I can do about my new iPad being very, very jerky and slow?
FACT - The multitouch screen is unresponsive and I have to press and press and press to select what I want before it reacts.
It's an iPad mini with retina, so it's got the new chipset which runs really, really fast.
FACT - What happens is:
I start up pages and it freezes completely for quite a while before allowing me access to my documents.
I go to settings and it freezes up totally for quite a while before allowing me access to my settings.
Is there a cure? I get similar problems on my acompanying really, really fast iPhone 5s.
PS
Plenty of memory left so no problems there - only about half used and they're both 32gb.
...and my beloved iPad2 never used to do this either.

If You Think iOS 7 Feels Slow Here’s How to Speed It Up
http://osxdaily.com/2013/09/23/ios-7-slow-speed-it-up/
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

How to best achieve slow motion and fast motion

Hi - I am new to the forum and a basic user of Premiere Pro CS5. I am working on a project shot at 24 fps, and would like to do slow and fast motion.
From what i understand there are 2-3 different ways to do this in Premiere - choosing speed/duration of the clip from timeline, or choosing time remapping form effects panel ot using rate stretch tool. Wondering how do these compare and which is better - any pointers for this will be great help. Also is slow motion and fast motion better done in After Effects than Premiere. Or any recommended plugins that would work on cs5 and cs5.5. Thanks.

The main difference between using time-remapping and just using time-stretching is that time-remapping allows you to change the speed quite flexibly at different times in the same clip, whereas stretching just changes the rate for the whole clip.
See this page:
"Change speed and duration for one or more clips"
> Also is slow motion and fast motion better done in After Effects than Premiere.
After Effects has far more control, especially with regard to how new image information is created between the original frames when you change speed and require frame interpolation (frame blending). Pixel Motion and Timewarp use a very advanced motion vector method (based on the Foundry's Kronos software) for doing this.
See "Time-stretching and time-remapping".

Slow-Motion and Fast forward

Hi,
Let me know if you can implement these functions with OSMF.
Thanks
Steve

If you use RTMP streaming with FMS you need to check the docs for NetStream.step() method:
http://help.adobe.com/en_US/FlashPlatform/beta/reference/actionscript/3/flash/net/NetStrea m.html#step()
Implementing this in OSMF is not trivial. You'll need to get deep into the OSMF NetLoader APIs (there are lots of posts explaining how to create custom NetLoaders in this forum).
You can also emulate fast-forward with seek() calls, and slow-motion with pause() calls This might be somewhat easier to implement and it will work for progressive content too, but the performance might be much worse than using the step() approach.
Let us know how it goes,
Andrian

Slow motion and resolution

Will using slo mo (fcp HD) change image resolution?

I am in charge of creating some segue sequences that are experimental in nature with layers, loops, and slow motion. The director posed the question that it might be a too severely "degraded" image quality compared to the other "talking heads". I just want to know what I'm dealing with when it comes to pushing final cut's filters, traveling mattes, etc to an extreme. < </div>
We call those Cool Assignments.
It's not easily answered. The absolute image quality is predictable by knowing how many filters or render steps are in your process. But the apparent image quality may be far better, as noted above. "Pushing" FCP's effects system is easy because it's so limited until you go out to third party tools and then you must have a firm grounding in codecs and compression.
You are going to distract form the heads not by offering up a degraded image as far as pixel quality is concerned. "Degraded" in your case, seems to refer to the deconstruction of the image by deliberate manipulation.
Here's another question, if I create a complicated sequence with layers, mattes, slo mo, etc. then export to a quicktime file to compress and then import it into the main timeline, will this ensure a higher quality overall? < </div>
As Brian and Zap are trying to add, "compress" isn't what you want to do. That's whey many of us move to Motion or After Effects for this stuff and then render to a lossless codec.

Slow motion and speedup during a single clip

Is there a way to take a single clip, and slow down portions of the clip, while speeding up other portions of the clip.
Is there a way to adjust playback speed using keyframes I guess is my basic question, so the start of the clip is slow motion, then the middle is played back at an accelerated or normal rate, then the end of the clip becomes slow motion again.
-Roger

Yes, is the short answer. Using the time remapping feature in the "effects" panel (top center of the screen, second tab from the left) you can set certain portions of the clip to play back at normal speed, then slow it down in certain sections, and then speed it back up. You can also cut the clip using the razor tool (in the tools panel at bottom right of the screen) and just reduce the speed of that section of the clip. The downside to using the time remapping (if my memory serves me - don't take my word for it) is that you lose audio, but the transitions from normal to slow-mo and back are much smoother. Using the razor tool, you simply place the timeline indicator where you would like to begin the slow motion segment, then cut the clip with the razor tool, the repeat the process where you want the slow-mo section to end. Then, select the section that you want to play back in slow motion, and reduce the speed. This is the method that was used before the time remapping feature was available. The transitions are not at smooth, but you can keep audio for the sections where the speed isn't modified. Just be sure to select the "ripple edit" check box when you modify the speed/duration setting of the clip (right click the video clip to get the speed/duration setting dialog box).

Slow motion and other effects are grayed out

Just switched from iMovie 9 to 11, and can't take advantage of the slow motion, instant replay and other effects, because they are all grayed out in the Clip menu. Why? I do not see the "convert entire clip" option referred to in the help file. What is wrong?

Yes, that is it. The trailers are pretty scripted.
If you want to add an effect to a trailer, first complete the trailer.
Then, in the Project Library List view, right click on the trailer name, and select DUPLICATE. (This will give you a copy of the trailer in case you want to edit it some more.)
Then, with the trailer name still selected, click FILE/CONVERT TO PROJECT.
This will turn your trailer into a normal project, and you can use any of the capabilities of iMovie, including the slow motion and instant replay effects.

Slow motion and Normal speed?

Can I take video shot 720p at 60 fps and use both slow motion and normal speeds in the same video??

Time Stretch is where I would start. If you need to apply that Effect to only part of a Clip, just use the Razor/Scissors Tool, to Cut that Clip, into the segments, where you wish to apply Time Stretch.
Posterize Time can be effective, as well, but from my reading of your needs, I think that Time Stretch (Rt-click the Clip, or Clip segment and apply).
Good luck,
Hunt

Slow motion and reminder setting

Guys,
Is there a function for slow motion and for setting a reminder for a program rather than recording?
Cheers

No slow motion that I've found.

Looking for DVD player that will repeat a segment (loop) and slow motion

I have iDVD and the DVD player in Snow Leopard, but want to be able to play a dvd in step-by-step frame, and also (especially) to loop round smaller segments. I use it for dance video, and need to see dance moves over and over without necessarily playing the whole segment. Is there any software I can buy/install to do this? Like Cyberlink for Mac? Thanks.

I searched for a DVD player with a jog shuttle -- and you're right. They're all but impossible to find! I havent' found one made in the past 5 years!
I don't know of any way you could accomplish the same thing with software either.
Most DVD players have slow-motion and frame-by-frame features. (Even my cheap $40 Toshiba.) That may be the closest to it.
