Slow motion, subtitles and extracting freeze frames

hi friend,
had a few queries if someone can help.
1) want to play a single clip in a project in slow motion. how can it be done?
2) can subtitles of the voice be added? there are only three titles and only possibility to have one in a clip.
3) can a freeze frame be exported as a photo to camera roll or photos? or can a still frame in a video be extracted as a photo and sent to the camera roll?
thanx,

1. You will need to buy an slow motion video app.
     There are a few in the app store that slow down video that is already shot.
     Export the slowed video to the camera roll, and use it in iMovie.
2. Subtitling is not an option in iMovie.
     You can add 'middle' titles, but using this to make subtitles would be slow, and add transitions which is anoying.
3. There are apps that can make stills from video.
     Or you can do a screen grab of the ipad; hold power and Home button.

Slow motion, reverse, and speed up

In iMovie 08, I cannot figure out how to make the video play in slow motion, reverse, or speed up. Is there any way to do this with iMovie 08?

Slow motion recording and playback with Flash Player with web browers

Hi,
I am using a MacBook, have installed Flash Player 10, and everything was great until a couple of days ago. Then, my audio playback with Flash seems to be in slow motion. I record my voice in this program call Voicethread using either Safari or Firefox and what it should be a 3 seconf audio track seems to be elongated to 9, streching my voice like it is on slow motion. I have tried everything that it is recommended (restaring, uninstallins, reinstalling, etc) and NOTHING... I have spent hours already trying to fix this issue that came from nowhere... 36 hours ago was working just perfectly!
Any suggestions?
Many thanks,
Luis

Adobe Flash Player has also been crashing periodically on 2 of my computers, I'm still running XP, one of them a powerful HTPC, Dell Optiplex 755 SFF over a new Cable Internet Connection. Buffering, Lagging, crashing when streaming video for Catchup TV (Freeview) via Firefox Adobe Flash Player Add-On, does not happen on Youtube though. Lagging & Crashing does NOT occur AT ALL in Google Chrome, but I hate that browser.
Have tried the usual disabling Flash Hardware Acceleration + Protected Mode, setting storage to Unlimited, disabling FF Ad Blockers + Hardware Acceleration, cleaning Caches, updating program versions, everything bar reinstalling programs. It's not happening in Chrome, why in Firefox?

Importing music very slow 0.5x and iTunes freezes during every backup

Everytime I plug my iPod into my computer it freezes and I need to end app also while importing new CDs they are taking about 2-3hrs and it's only transferring at 0.5x. My pc is a windows xp sp3 2.68GHz 760 RAM

I have had some help and have tried many things to resolve this. Bottom line, it was the CD reader. I tried to load the same "slow loading" CD into someone else's computer and it went in faster than I've ever seen (9.5X - 13X). I borrowed his CD reader and put in in my machine and it worked fine for the 5 CD of the 100 I had left to load because they loaded so slow. This time, there was one of these 5 that read in at 1.1X. Again, I borrowed a different CD reader, put it in my machine, and it read fine. This problem was NOT program/system related: I tried cleaning files, running Adware, Antivirus, defrag, etc.) I read/burn lots of CDs and must wear them out in my laptop.

Slow boot up and computer freezes...???

hey all. This problem just started this week. I think it might be due to the 10.4.10 update. anyway, i noticed that the boot up time is considerably slow now. during startup w/ the gray screen and the apple logo in darker gray, that little clock face with it blinking clockwise shows up below the apple logo. this normally happens when i upgrade the software... but its happening everytime i boot up the computer.
also, the computer freezes up... once when i was watching a movie on quicktime and i moved the mouse to see how much time left in the movie. the other time, when i was listening to music andi moved the mouse. the screen gets darker, but not totally black, like the computer is saving power and a message saying that i have to hold the power button down for at least 5 seconds to turn off the computer. the message is in two other languages. this happened in a period of two days....
any idea on what could be the problem and how i go about solving it??
thanks!

Hello,
First thing that comes to mind is... how much free hard drive space do you have? To view this information, open a Finder window. The information is the bottom of the window. Never allow the drive to have less than 15% free hard drive space because that will slow down your Mac faster then anything else.
Ok... it's freezing up on you. Grab your system restore disk(s). Make sure your Mac is turned off. Now, press the power button, hold down the C key and insert the restore disk all at the same time. Let go off the C key when you see the Apple logo on your screen. Now, by default the Installer window will open. Quit the Installer from the Menu and instead click Utilities/Disk Utility. When DU opens, select MacintoshHD in the panel on the left. Then click Verify. If DU reports errors on the drive, click Repair. Now, while you have DU open, also, Repair Disk Permissions.
Get Onyx. It's a great disk FREE utility and can fix a myriad of problems. You can download it right from the Apple site here:
http://www.apple.com/downloads/macosx/systemdiskutilities/onyx.html
The message you are seeing is called a "kernel panic" and you can find information for that here: http://docs.info.apple.com/article.html?artnum=25392
Hopefully something has helped!

Slow motion videos and distorted sound

Hi, using Vista, IE9, latest verison of Flash, video goes into slo-mo after a few seconds and sound distorts. Any ideas?

To help troubleshoot could you give us the exact version of the version of Flash that is installed?
Flash Player version
When reporting issues with video or audio, it's also helpful to get your system hardware and driver details. Instructions for finding this information can be found here:
dxdiag report instructions
Finally, sometimes video and audio problems are caused at a lower level and not directly related to Flash Player. I recommend trying both of the links below to see how they perform. If the problem exists with both, then Flash Player is most likely not the culprit as the HTML5 video link does not use Flash Player when playing. You can verify the use of HTML5 by right clicking the HTML5 video and looking for the words "About HTML5" at the bottom of the context menu.

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.
Regards,
fh

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

Odd issue with slow motion and exporting

Hello,
I have a project with footage taken at either 24p or 60i settings on a Canon HF200. I'm using 7.0.1, ProRes 422 selected. Frame size is set to 1920x1080. I'm exporting using the "Share" menu and the Apple TV preset.
The project is divided into sequences. One of these sequences (whose source material shot using the 60i setting) is set to play in slow motion using the "change speed" option set to 50%.
Here's the odd part, to me at least:
When I export just the slow motion sequence of the project, it plays perfectly (good quality, smooth not jerky, no shadows/trails). But when I export all sequences joined together, the slow motion sequence (and just the slow motion sequence) appears stuttery, with trails on every action by the actors.
Another odd bit: when I export just a subset of the project including the slow motion sequence and everything after it, again the slow motion sequence plays as intended, after export. So the problem only occurs if I export the slow motion sequence with anything before it included.
Thanks in advance for any help.

Problem solved, but I'm not sure if it was my re-importing the clips, or un-checking the "frame blending" option that did it. I did both for no particular reason, and one of them worked.

Slow motion plug in?

Is there a plug in for final or motion for slow-motion that is better than frame-blending, motion-blur and optical flow?

How much money have you got?
ReVision Twixtor comes to mind, US$600.
http://www.revisionfx.com/products/twixtor/
Easier to reshoot or shoot properly with enough frames per second to make the task more palatable. Optical flow is similar to pixel vector path estimation technology used in Twixtor.

Compressing .mov to mp4 comes out in Slow Motion!

I have Compressor version 3.5.3 but I don't think that's what the problem is. I'm trying to compress an 11GB Quicktime file down to a couple of GB.
It's a PAL .mov file, 1920x1080, 25fps, 48000kHz/16.
These are the Settings I chose :
Video: Encoder MPEG4, 1920x1080, 25fps,
Key Frame interval: I change 15 to 25. Is that wrong?
Bit rate: medium VBR
Audio: Mono because Stereo greyed out 48000kHz.
Bit rate 64kbps is what comes up with 48000kHz. (When I changed it to 16bit it brought 22000kHz)
Frame Controls Option is off. Is that correct?
The result was a clip in Slow Motion Video and Audio alike.
What did I do wrong? Is there an incompatibility somewhere? I'd be most grateful for any suggestion. Thank you,

Hello Russ, these are the 3 Inspector screenshots you requested:
1) Inspector for the Quicktime file to be compressed:
2) Inspector Summary 1
3) Inspector Summary 2
4) Inspector Encoder 1
5) Inspector Encoder 2
That's how I ended up with slow motion in the converted mp4 file. What do you make of it?
Many thanks in advance for any light you could throw on this.

Decent slow motion without artifacts?

I can't get decent half speed slow motion in AE CS6. Frame blending looks horrible with all the double contours in fast moving objects, and pixels motion looks much better motion wise, but introduces horrible motion artifacts. I also tried Pixel Motion using the Timewarp effect to have more control over tweaking it, but no matter what parameters I change, I still get the artifacts. So it looks like After Effects by itself doesn't have a good way to do slow motion that looks great, at least not for the footage I'm using.
Are there any other filters I can try, whether in AE or 3rd party that will go a great job?
Thanks,
Sebastian

As Rick said, blaming it on a specific plug-in/ feature is kinda missing the point. Half the magic happens during shooting. If I knew I'd want to slow things down, I'd get the camera that would offer the highest framerate and least compression, even if it means an expensive rental of an ARRI camera. If that's not possible then you'll have to make do with what you have and try to fix it in post. Using a sophisticated tool like Twixtor no doubt is always an option, but many times it starts with simpler things like trying to reduce block artifacts or evening out color. Such basic stuff often helps the algorithms a lot. The same as you would when doing keying. Also you can always try to mask specific parts and slow them down in separate pre-comps. It may give alignment issues, but if you want to do some sky replacment or keying, it would be acceptable to proceed this way...

How to properly timewarp 59.94 footage for slow motion effect for 29.97 output

I have footage filmed in 59.94 that I want to use for slow motion effects and output to 29.97. Using timewarp I seem to get duplicate frames at times. What would the best workflow to accomplish the cleanest result? I've tried interpreting the footage at 29.97 and keeping it at its native 59.94. At this point I feel like I'm just confusing myself further by just trying random things. Thanks!

Always interpret footage as what it really is. If it is really 59.94 progressive then that's what it should be interpreted as. It will play at the right speed in any comp of any frame rate. IOW, if the footage is 10 seconds and you put it in a 99fps comp and play it back at full frame rate the clip will still be 10 seconds long. If you put it in a comp that's 15 frames per second, the clip will still be 10 seconds long.
Make sure you understand that.
There is a chance, and a good chance, that your footage is actually full frame 59.94 fps video. That's why I suggested putting it in a comp that's also 59.94 fps and checking for duplicate frames.
There is also a chance that your footage is actually 29.97 fps interlaced. If you separate fields and look at the footage in a 59.94 fps comp you won't see any duplicate frames.
To change the speed of the clip you just need to apply Time Remapping, Time Warp, or any of the other Time Time tools in AE. It doesn't make any difference what the frame rate of the composition is, you'll be changing the length of the clip.
To keep from creating duplicate frames you either need software that interprets the new, extra frames or you need to use an exact whole number multiple of the frame rate for rendering.
Where did you get the footage? What Camera? What are you trying to do with it? What is the final destination (delivery) for your project.

Creating slow motion footage

I'm going to need to create some slow motion footage and it seems like I can do this with FCP under the Speed option. If so, just curious why people buy camera specifically to do super slow motion. Are there quality issues when doing it in FCP?
Thanks.

When you take 30fps...and slow it down to 50%, half speed...what you get is 1 frame repeated...it shows up twice. So the action is not all that smooth. Go to 33% and that 1 frame is repeated 3 times.
Now...take a camera that shoots 60fps, slow that down to 30fps, you get frame for frame...1 frame not repeated, so that 1 second shot at 60fps is now 2 seconds, and smooth. Slow that down to 24fps...that's even slower. Shoot 120fps...that's even slower and smoother.
So, if you want slow motion, you need to shoot more fps.

Slow Motion Software

I do a lot of wildlife filming in Africa. Can't afford a camera which will give me the slow motion option. Looked at the TWIXTOR software from www.revisionfx.com, who claim compatibility with PPro CS5. Has anyone any other suggestion of other software which works on a similar principle (creating intermediate frames) and produces good quality slow motion for HD?

Twixtor is the first one to think of. I know there are a few more, but can't remember their names. I would not look any further and just choose Twixtor. Be prepared for long rendering times however.
Yes, Twixtor appears to be the gold standard for this in the Ae community. I saw a short film by a guy who was slowing down some footage to really small percentages, like 1%, and the outcome was pretty amazing, almost as if it had been shot with a high speed camera.
The long render times are because Twixtor analyzes the clip before slowing it, and calculates motion vectors, and creates tween frames and blur in accordance with the motion contained in the video.

Slow Motion/QT Pro 7

Hello:
Can a film or any visual image opened in Quick Time Pro 7 be played in slow motion? And if so, how?
Thank you

QuickTime Player has an A/V Controls window (not supported on all machines) that can play from one half speed up to three times speed.
The Pro upgrade version can adjust visual affects permanently by simply adding the video track (scaled) to a longer (or shorter) audio track and then extracting the modified video track (Movie Properties window).
Take a one minute video and add it scaled to a two minute audio track and then extract the new video track to have "half speed".
