Slow motion playback

I have a unusual question compared to some of them I have seen here, but here it goes:
My mother is a college basketball coach and needs to get some upgraded video equipment for use with recording games, practices and camps. They currently use VHS and then are able to tape and then playback the recording for the players right away. They have something called a "cowboy remote" that allows them to freeze frame, go slow motion both backwards and forwards to analyze plays and drills, as well as the player's shots and movements.
Will Final Cut allow them to do these things if they were to purchase it for their iMac or is it just a matter of finding a DVD player that will do these things on playback?
Is there a particular type of camera that would be needed in this situation?
Thanks.

Yes, you can both view the footage within FCE in slow motion and edit it so that it always plays that way. If you edit it so that the actual clip is played in slow motion (and you're not just viewing it at a reduced speed) then it will also play that way when burned to a DVD.
Keep in mind that FCE has a relatively steep learning curve as well. Training books or internet tutorials are definitely recommended.

HT3176 How can the slow motion playback speed be adjusted on Apple TV (pause and clicking right/left)?

I am looking to adjust the paused slow motion playback speed of Apple TV. On one of my Apple Tv's when paused I can click right or left to view tv in frame advance (or one second advance) on a different Apple TV there does not appear to be any advance even after multiple clicks. But, it will jump 10 seconds when paused and left or right is held down as it should.
Third gen. (A1427) Apple TV Software version on both 7.0.3

Unfortunately with that speed you are not going to have a good experience with HD streaming. I would make sure everything is set to stream SD. Go into the settings - iTunes Store and you can switch there for any purchases/rentals made through them.
If you use Netflix (or other streaming sites) go into your account(s) and see if you can switch to a lower quality stream. I know Netflix has that in place.

Video shot specifically for Slow Motion playback

I thought I might try starting a thread for sharing video shot specifically for the purpose of playing it back in slow motion. For the first example, I shot this flag flying on a perfectly clear day. We have had a lot of really clear blue days lately much to my delight.
My Panasonic DMC-GH3 can shoot 1920X1080 at 60 (59.94) frames per second. That is frames, not fields. So interpreted at 29.97 frames per second it plays half speed. This was taken a step farther and played back at 24p. So if my math is correct, it is playing at 40% (close enough).
Funny, but the camera actually has a setting to shoot video to play back at 40% but it seems redundant to me. Perhaps if the video was never going to be edited, just played back, that could come in handy.
I used a recording from the US Army Band because I was in the Army and I am just used to hearing it played by the Army Band. I thought of adding the lyrics since I really like them. All four verses. I just didn't have enough footage to do it right and I love the sunshine and blue skies. So here is a link to the four verses for those who want to play the video four times and sing along. Nobody? Are you sure? I did it. Couldn't help it.
I am probably going to put up a couple more copies. One with the Pledge of Allegiance and one with the first verse of the National Anthem. In the meantime, I am enjoying all that blue sky.
If your camera can shoot at a higher frame rate to play back at 24p, please post some examples. If you are particularly good at using Premiere Pro to modify the playback speed of video, let's see what you've got.
The camera was siting on a GorillaPod shooting at approximately a 30 degree angle. The lens was my 100-300 set for 183mm, the equivalent of 355mm on a 35mm camera.
ISO 200. This video has not been modified in any way other than interpreting it to play at 24 frames per second, to trim off the beginning and the end (to eliminate the shaky setup and take down of the shot), and I also added cross-dissolve transitions at the beginning and the end. No color correction of any kind and no stabilization. This is what the camera saw.
I really love the flag of the United States. If you live in the United States I hope you do too. Today is Washington's Birthday. So Happy Birthday to the Father of our country. Our first President. This is my present to our founding fathers on this day, and I chuckle to think about how shocked they might be at the number of stars on the flag, and I am sad when I think how mad they would be if they knew how far we have strayed from the principles they fought and died for.
(I'll bet old Ben Franklin would love the Internet though.)

Steve, regarding my request getting inside flag and changing shutter speed etc..
I have to admit right off that I don't understand this myself as I should...and I don't have a motion pic camera OR the DSLR ....which I can get in April ...at which time I will be off to the races trying to figure out how to use it.
But the gist of what I was getting at ( though hazy and not understood by me ) I'll try to explain...
Motion pic film cameras with the mechanical gizmo that pulls down the film ( frame by frame ) have a rotating shutter ( the gizmo is typically called a mitchel movement I think ). The rotating shutter has a mirro on the back side which allows a person to 'see' via some magic stuff ( prism ? ) what is in the frame ( eyepiece ). I guess it's similar to a SLR mirror but this one spins.
This is what it looks like
So, a normal setting for that shutter is 180 degrees... and it spins so that each frame gets 'exposed' by the open part of the shutter. Then when the shutter is spun to the closed side ( no light getting to film frame ) the 'next frame of film' is dragged down into place to be exposed. So that happens typically 24 times per second. It is pretty fast.
Some motion pic cameras can shoot even FASTER ( amazingly )...and you can therefore increase the FPS. Then as you know when it's played back at 24 FPS in projector, it looks like slower motion.
Unfortunately if the FPS is increased the 180 degree shutter may not be letting in enough light to get a good exposure anymore... so that shutter can be adjusted ( called the shutter angle ).
So a 45 degree shutter would let a lot more light hit the film ...cause it lets more light through its rotation time. This is the part where I can totally confused....and hopefully I'll learn more when I get the DSLR how this is handled with modern digital camera.
Cause, if you let more light hit the film by adjusting film motion pic shutter it stands to reason there will more " blur " from the longer exposure. However, this is offset by the faster FPS speed... so this is why I am curious about it...
As a point of fact motion pic cameras can be synchd to CRT screens using a mechanism that times the shutter to coincide with the horizontal 'lines' of the CRT ( timing of frames of interlaced signal )... and the shutter has many 'angles' it can be adjusted to ..
So, anyway, I guess this is something to explore when I get that DSLR...
I was thinking it might look cool to have slo mo with more 'blur' to make something look a little ghost like...kinda like my flag picture with time exposure...
crazy idea...

Record and playback video in slow motion

Hi
I am COMPLETELY new to labview and am having some trouble.
I would like to record a video using a USB camera and be able to play it back on multiple occasions at different speeds.
The file attached is what I have so far. The signal generated at the top is controlling the equipment I am recording. Currently, I am saving the video to the hard drive in AVI format and retreiving it to watch again. However I would like to be able to play this at different speeds and be able to pause/rewind. Is this possible? I would also prefer not to have to save and retreive the file and much prefer it to stay within the system memory.
Thanks in Advance
Alex

Hi!
In your program you set the "frames per second" input on the "Init AVI" Vi to 50. If your camera is set up to acquire 50 frames/sec this is ok. But your "playback" loop will (as it is) run at much higher rate, since it is not limited in speed. You need to control the playback rate with a delay function (maybe the Wait (ms)-vi). If the acq-rate is 50Hz, you need to limit the playback loop to 50 iterations per sec -> 20ms delay.
Set the delay to a lower value for a faster playback, or higher value for slow motion playback.
If you decide to use the AVI-vi:s you need to associate the video with a file. You can however keep the frames in memory by simply create an array of images and write to them instead of to the AVI-file. Modify your code like this:
1) Create an array of IMAQ-images, Note that you need diffrent images on each index in the array.
2) In your acqure-loop. Instead of writing to the AVI-file, write to the array at index "i". Note that you must modify this image, so retreive the image-ref at array index "i", then modify it by writing to it, the put the image-ref back in the array.
3) In your playback loop.Read image-ref to display from the array by index "i".
Done
Best regards

Slow Motion Video in Revel

Few questions...
When will slow motion playback be supported?
Are the slow motion ranges saved in the video or is this extra information not stored in the video container?
Will the ability to save video to the camera roll be added?

I'll take this feature request to product management. I can't say if or when such support will be available. In the meantime, as a workaround use iMovie to export your video with the slo-mo effect to your Camera Roll so Revel can import the processed version.

Remove slow motion quicktime

When I open a video make with gopro a 120 fps under the timeline( in quicktime) there is a timeline for the slowmotion that show me automatically the video in slowmotion. I don't want this and i'd like to know how i can remove it.
Quicktime 10.4, Yosemite, macbook retina 13(2013)

I know this....but is like close the eyes to don't see the problem.....i need 120 fps.
Had hoped the original poster might provide additional information regarding why high frames rates were required in his or her workflow but not needed for their normal intended purpose of creating ultra smooth slow motion effects as such information might lead to better alternatives than those already provided. However, as three days have already passed, I thought it time to recap this issue for the benefit of other users who might be interested.
BACKGROUND: The basic problem seems to be the fact that the ability to record high speed frame rate video has become more and more common on various consumer recording devices. Originally used by professional and top of the line prosumer devices to provide slow motion sequences during editing, this capability is now available to the average home movie editing enthusiast using the current QT routines built into the latest Mac OS X v10.10 and IOS 8 software. Frankly, I am at a loss to understand why some users are opposed to having these features available to them at the QT X and mobile QT player level. For any persons not familiar with this feature, here are some captured screenshots:
Yosemite QT X Player
IOS 8 Photos App Player on iPhone 5s
As you can see in each of the images above, when the QT player software recognizes my 720p120 GoPro video file and automatically displays a secondary playback control bar below the standard controller. This controller allows a user to set "in" and "out" points for slow motion playback. In the case of the sample above, the movie begins playback at 120 fps, plays the middle segment at 30 fps, and then switches back to 120 fps for the final video segment. Thus, these players can be used to preview slow motion editing potential. By adjusting the position of the "in" and "out" markers, a user can play all, some, or none of the video clip play in slow motion. Such previews can even be shared as "proofs" with other Yosemite/IOS iCloud users but since they contain the original source data scripted with slow motion playback data/instructions, they are frequently too large for emailing as simple attachments to anyone else.
Such player content can even be saved as a mini QT Player "project"— i.e., saving the file copies the clip as currently edited to a new file container which is paired with an additional AAE (described by the Finder as a "Slow Motion Video Sidecar") file. The AAE file appears to be basically be a PLIST file containing "slow motion" playback data/instructions which I assume represents the embedded modifications to "shared" videos. Here is an image of such file content:
Sample AAE "Slow Motion Video Sidecar" File
It should be noted that these slow motion files apparently cannot be directly exported from the QT X v10.4 player app—or rather, I was not able to do so. (I.e., files exported normally but without any slow motion effects.) However, it is a relatively simple matter to "share" a "com.apple.AVKit.Share" file to the Mail app, drag it to the Desktop, and then re-encode the file as an M4V file suitable for many uses using the built-in system encoder. I.e., export result is a 30 fps file retaining both normal and relative slow motion playback segments. This is a handy, although less accurate, alternative to the use of professional or dedicated video editing software for the creation of slow motion clips to share with friends and family or distribute as "proofs" to clients. If you research the internet, you should be able to easily find several articles and forum topics complaining of the lack of such basic, built-in support for such clips over the past few years.
In any case, the QT X player can play the 120 fps files with or without applying any slow motion effect. Other players like QT 7, VLC, NicePlayer, etc. avoid this issue by simply ignoring the significance of such excessive frame rates and attempt to play the files at their original frame rate by dropping frames as needed to keep up with the data throughput. Therefore, I can't really attach much credence to the idea that the previously posted suggestions "is like close the eyes to don't see the problem" and that the "need" for 120 fps files here (without explanations) may be less of a "need" than indicated. As previously stated, the recording of content at 120 fps (or greater) is normally performed to comply with specific future editing requirements and its indiscriminate use is just a waste of file space and battery life for the average "videographer" who simply thinks that "faster is always better."
BASIC RULES OF THUMB FOR NON-PROFESSIONAL USERS:
Use high frame rate recording modes if you think there is even a remote possibility that you will be creating slow motion clips/segments from your recorded content AND you have sufficient storage media AND battery life to handle the project at hand.
Use the most current QT X or IOS 8 media players to quickly preview or share high frame rate clips with slow motion effects without having to access professional or dedicated video editing software.
Use the most current QT X or IOS 8 media players to create and save slow motion settings that can be recalled later.
Use a professional or dedicated video editing app to create and/or share slow motion project content where frame accuracy and/or fluxing is paramount.
Use an alternative media player to preview high frame rate clips when viewing content at its original frame rate AND it is too much trouble for you to adjust these players for non-slomo playback (i.e., a single swipe of a finger or clicked mouse). But remember that higher frame rates and higher resolutions mean higher playback data rates which may make playback "choppy" at best on some systems. (E.g., my 720p120 sample file has a data rate on the order of a VC-1 encoded Blu-ray disc.)
Hope this post may be of use to amateur videography Mac users contemplating the use of newer, high-speed video recording devices and how to use the basic support now available in the latest Mac OS X and IOS 8 operating systems as part of Apple's QT X modernization program.
Happy New Year to All,

Mac book pro (late 2013) has a lag when sculpting and rotating models in Zbrush only when using my Wacom-capture tablet (if I use a mouse or trackpad its fine no lag). Also Premiere Pro CS5, playback is almost like watching footage in slow motion.

Mac book pro (late 2013) has a lag when sculpting and rotating models in Zbrush, but only when using my Wacom-capture tablet (if I use a mouse or trackpad its fine no lag).
Also Premiere Pro CS5 playback is almost like watching footage in slow motion, Premiere Pro is installed on the main drive but the footage is on an external drive connected with USB 2.
I'm wondering if it is just a problem with the Mac USB drivers maybe not supporting USB 2 ? (Because I have also installed Window 7 on this same MacBookPro and tested the same software "Zbrush and Premiere Pro" And they both work perfectly on the Bootcamp Windows 7 install, and so its using the same hardware so it has to be the drivers right ?)
Any help would be great, Thanks

Slow motion, reverse playback and others

Dear members:
After doing some research that included help files for Final Cut Express HD and Apple's support pages I haven't been able to find a straight and definited answer to my question.
I am trying to find ways to add slow motion, reverse playback and fast playback effects to my sequences in Final Cut Express HD but haven't found a way to do it. Some pages I found seem to indicate that these functions may not be available in Final Cut Express HD but they are not specific enough. I honestly can't believe that an application that is meant to provide professional results wouldn't offer these which are probably some of the most used effects in video.
Do any of you know if and how these effects can be used with Final Cut Express HD ?
In case it can't handle these effects, how much would an upgrade to Final Cut Pro HD cost if I am coming from Final Cut Express HD ? Is there an (reasonable) upgrade path ?
Thank you in advance for your help.
Best regards,
Joseph Chamberlain

I'm sure you can do this w/ FC3xpress - although I haven't used that app in years- but you can try this:
-Select the clip you want to add the 3ffect to then press Apple-J
-That should bring up the menu where you can determine the new speed percentage.
-If it doesn't have the Reverse checkmark option (I don't think it did in earlier versions) you can do a negative percentage to make the clip play in reverse.
Also it looks like there is no way to upgrade from Final Cut 3xpress to Final Cut Studio
You can upgrade from a few apps but Express isn't included in that list.
The list is here if you'd like to see for yourself.

And if you click the buy you have the option to buy the upgrade (intead of the crossgrade)

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?

TA44469 in windows, playback video is in slow motion why

I uploaded my videos from my iPhone 4s to my PC (Windows Vista), and when I playback the video is in slow motion. Audio is fine. Why? I checked for Quick Time updates, and I am good. I shut down all other programs, and it still plays back in slow motion. How can I correct this?

Video is synced from the computer to the iPhone via iTunes. You need to load the video into iTunes, make sure it is iPhone compatible before you do that, and once it is in iTunes, then sync to the iPhone.
Never said what computer OS you were using. Also, the computer processor, amount of RAM can make a difference with HD video.

HP 620 Win 8 64bit - Please fix this HP! No sound and audio/video playback on slow motion

HP 2000 Notebook - No sound and some slow motion in video playback

I had plugged in headphones while watching a video on youtube.
The video on youtube suddenly got snow and stopped playing and the sound in the computer stopped working as well. The sound icon has a red X.
The system is not detecting any problem.
I am not computer savvy so need simple steps please.
I checked the speakers, tried to update the software but no software update needed.
I have tried rebooting.
My last option is to do the recovery which I do not want to do.
PLEASE HELP!
Also the DVD player sometimes do a slow motion play while doing T25; it wasn't doing this before. I thought it was maybe how it was but its not.

When I have streamed them from my mac to my tv, they're in slow motion, and choppy.. the audio is fine.
With my iphone 3g, my videos streaming are fine.
Any ideas why this would be?

This is clear as mud to me, but here it is:

Qosmio G20-139 slow video playback sound ok

Hi,
I no longer seem to be able to play video files, play DVDs, or watch TV as the playback is in slow motion but sound is ok except on the TV.
Have tried to uninstall Graphics driver but it won't let me saying something to the effect of unable to uninstall as required to boot.
Also looking into uninstalling /reinstalling Video driver but can't find what it is. Is it the same as the Graphics driver (NVIDIA Go Geforce 6600)?
This all started (i think) when i tried to use a netgear router insatllation CD but stopped it half way even though it said not to... Then whole system went incredibly slow and crashed a lot for a while (even Word, Excel and Powerpoint) but think some updates have sorted that out.. but it still doesn't seem to be able to handle too much going on at once like before... plus some site heavily using javascript have also gone ridiculously slow.
Besides using product restore CD as not to hand as moved to diff country... Any suggestions please????
OS: Window XP MCE
Regards,
Angela

Hi
> Also looking into uninstalling /reinstalling Video driver but can't find what it is. Is it the same as the Graphics driver (NVIDIA Go Geforce 6600)?
The display driver and the graphic driver is the same ;) some people call it display driver and some people say graphic driver
Im not quite sure why you are not able to watch movie files properly but possibly you would need some kind of codex.
The codec can be downloaded from different pages and many packages contains different codex.
Personally Im using N K-Lite Mega Codec Pack because it contains most necessary codecs.
I think its worth a try to install it!
Furthermore I recommend cleaning the OS using the CCLeaner its free tool and I had a good experience with it

Help! Movies from iPhone 5 play in slow motion when opened in Quicktime on PC

Hi there,
I was hoping someone may have the answer or have encountered this problem as well, as I have been unable to find anything on it elsewhere on the net.
I have transferred some movies, taken on my iPhone 5, to my PC. However when they are opened in Quicktime (as recommended) they play in slow motion.
However, the sound still plays at normal speed.
I have already tried going into the QT settings where you can speed up the playback, but this doesn't work either, no matter how fast I set it to - they still play super slow.
Although they are taking up heaps of space, I am worried to delete the movies off the iPhone in case they have not copied over properly and I lose the originals!
Any suggestions?
Many thanks!

Hi Matthias, thanks for your response!
We are running on Windows XP, is that what you mean? I will try and download the VLC player and see what happens. Are iPhone 5 movies higher res than iPhone 4, as we can play those?
If it is the system, do you know whether or not if I save the movies to our PC, then transfer than to another computer, should they play ok? I just don't want to delete them off my phone and have them permanently slow, iykwim?
Sorry if my ignorance is showing - I'm not overly tech savvy when it comes to this stuff!
Many thanks again!
