Perf. implications of high frame rate

What are the performance implications of using a high frame
rate in Flex. Our designers suggest that a frame rate of 60fps is
smoother animation. They are creating Flex components with Flash
CS3 and want to use the higher rate and use them in Flex.

As you might expect, a higher framerate is going to consume
more of the CPU. It's pretty much that simple. Some end user's
computers may not be able to keep up with the framerate and their
experience will be less smooth, probably less smooth than if you
used a smaller framerate. I suggest you experiment.

Cannot create slideshow with high frame rate

I have just bought QuickTime Pro version 7. I am using Windnows XP SP2 on a Pentium D machine.
I am trying to create a movie with still images I captured from my digital camera. I created a 10 seconds slideshow and set the frame rate to 30 frames per second. I then saved the file as a Quicktime movie. When I played the movie with my QuickTime Player, I could see actions for the first two seconds only. After that, the picture didn't change eventhough the progression bar was moving. Once the movie reached the end, the player then changed the frame to show the last picture of my slideshow.
In short, only the first 60 images are shown in the first 2 seconds. Then the slideshow was stuck with the 60th image, until it changed to the 300th image at the very end.
Does anybody has the same experience? Did I do anything wrong?

One more thing. If I set the frame rate to be less than 10 frames per second, it works fine. It just won't work with high frame rate.

High frame rate outputting

Is it possible, having shot footage at 100fps (with a timebase at 25), then interpreted footage as 100fps to maintain the high speed frame rate, to output this as a 100fps file, to be watched at the same speed? I'm guessing only some machines/players can support this, but this is separate issue. I'm wanting to find out about getting a workflow for high frame rate footage in Premiere (or After Effects, as I read somewhere else this can support 99fps outputs.)
This is not a question of slow motion shooting/overcranking- there seems to be the capability to shoot high frame- is it possible to retain this in order to output it at the same speed it was shot?
But the issue seems that high end footage (say from a RED for instance) can only support a timebase framerate of maximum 59.96 (although something like a GoPro can go to 120p)
Would be great to discuss this more- its only a matter of time before this becomes more prevalent...

If the GoPro 2 does 60p I'd do that if you want slow footage from that cam too. Either way I'd do a custom project storyline at 720/30 frames. Then do some web searching on the term "conform" because you'll want (I think) to conform the fast stuff down and that will slow it down. You'll just import some portion of your 120fps footage from the event library and and choose Conform Speed from the Retime menu (command R). You can go beyond that by retiming further and by choosing Optical Flow for video quality. If that still isn't enough you might need twixtor but you may find that's workable. If you shoot at 120fps you'll get some seriously slow stuff after conforming and retiming slower.

4K Monitor Support - Higher Frame Rate Hz

To all those geeks who are trying to get 4K support from your MacBook Pro I have done it. Using SwitchResX, Belkin Mini DisplayPort to HDMI adapter it works on the Seiki SE50UY04. I am powering it with a MacBook Pro 2.3GHz Intel Core i7, 8GB 1600 MHz DDR3, running 10.8.4 OS X. I have plugged the Belkin into the left side LightingBolt outlet. I am running the Seiki monitor at 3480x2160 @14Hz. Images are fine. Screen a little slow, but usable. Have run a number of 4K videos using Quicktime7 and FlipPlayer and DIVx. FlipPlayer was not as good.
FYI. The Best Buy rocketfish Thunderbolt/Mini Displayport to HDMI adapter did NOT work. Nor did the right sided HDMI port on the MacBook.
Has anyone gotten this to work at a higher frame rate and how did they do it?

I did what you did, but with te timing from the link below.
It works with 15 Hz - wow!
Then I aranged the screens and restart again.
After this in system/monitor (standard controlfield) I can select as frequency 15 Hz AND 30 Hz.
Did it - got it! 4K at 30 Hz is what my seiki SE39UY04 is telling and what I can see.
For info: My miniDispayport to HDMI is Club3D CAC1153 (active one HDMI1.4)!
God luck

How can I change to a higher frame rate than 12 FPS?

Just got a good deal on a 15 in MACBOOK Pro running Yosemite with the latest Quicktime and iMovie. Is the best frame rate I can get out of this HD camera 12fps? I can't find anywhere to change it in QT or in IMovie.
MacBook Pro with Retina display, OS X Yosemite (10.10.2)

So you seem to correctly understand the information in the linked Use More Light! article.
studiojl wrote:... I don't like that at all...
Your emotion is irrelevant. It simply works the way Apple software is written. Perhaps some other computer system works different from Mac OS X and Apple camera apps?
If you intend to keep using Mac, you can take manual control of some camera parameters by using a third party add-on app such as iGlasses, Webcam Settings, or Sight Control.
studiojl wrote: ... what frame rate does it pick if I import one 30 FPS clip and one 60 FPS clip?
Whatever frame rate is set by the program of the software application you are using to record those clips.
You can determine that frame rate by making short test videos and watching it in QT Player.
The QT "Inspector" window will show you the frame rate for the clip.
Here's an example for a clip made in my low-light room:

Resize and display large images at high frame rate.

Hi,
I am looking for some suggestions on how to implement fast image display.
I have a device which creates 3000x3000 data arrays which I then convert into images. The device can output this data at anywhere from 5-50fps.
For display these are then resized to about 500x500 pixels.
The problem I have is that the resizing part of the process is quite slow and takes around 3/4 second .
So does anyone have an suggestions on I can get the images to the screen at a reasonably quick rate ?
I guess I need some sort of queue but has someone an example of how to do this ?
Thanks,
Paul

Hi Rox,
How are you verifying that you are loosing the frames during the saving and not during the acquisition? Are you able to determine where you are dropping frames? Is it at the beginning, the end or randomly? Thank you!

Acquire and save images at high frame rates

I am attempting to acquire and save images at a rate of 3000 fps for approximately 100 ms using a JAI 6740GE GigE camera, LabView 2011, and IMAQdx. I can acquire the images at the necessary rates, but am dropping images when I try to save them. The current test program I am working with contains a producer loop for acquiring the images, converting them into an array, and putting them into a queue, and a consumer loop to write the arrays to a TDMS file. Currently I can acquire and save the images at a rate of approximately 1200 fps before I begin losing a few frames. The code is attached below. I would appreciate any ideas to be able to save the images without dropping frames.

How do I take advantage of high frame rates while editing video in iMovie '09?

I have a GoPro Hero2 Hi-def video camera. It's capable of shooting up to 120 frames per second. How can I take advantage of that smooth slo-mo in iMovie '09?

hi kyle,
sorry, but just to elaborate on your response a little while ago here:
- i captured the 24PA footage using the advanced pulldown
- i captured the 24P footage using no pulldown
- i am editing in a 29.97 timeline now, as most of my footage was shot with 24P
please let me know your thoughts on how i should go about working with this footage!
thanks!

Is there a way to run firefox at a higher frame rate for those with monitors capable of 120hz?

I noticed that IE is smooth as silk when browsing websites compared to firefox. Is there an add-on or a setting I can change so that I can take advantage of my monitor which runs at 120hz?

Thanks, how would you synchronize the loops? I have gone through the Getting Started exercises and manual.
Why would synchronization matter? Did you want them to run independantly at their own speed or not?
Regardless, there's a synchronization pallette with functions for this, as Occurance.
Other solutions include a common loop counter and a case structure executing every X'th iteration, or having the faster loop send a queue or event every X'th loop that controls the slower loop.

High Latency with low frame rate

I'm getting 30 seconds of latency (between source video and
FME input window) when frame rate is set to 1.00 fps. With higher
frame rates, latency is very low.
Odd behavior: when switching from, say, 29.97 to 1.00 fps, I
see every frame (no frames are dropped), but they paint at only 1
per second (which means a large buffer is building somewhere).
After several seconds, the behavior switches to the expected 1 fps
(with all intervening frames dropped), but the whole thing is
delayed by roughly 30 seconds.
build: FME 2.5.0.2086
format: H.264 or VP6 (happens with both)
size: 352 x 240
bit rate: 200 Kbps
keyframe freq: 1 sec
Am I doing something wrong?

My encoding machine is a Gateway Pentium 4, 2 GHz with 1
GByte RAM, Windows XP Service Pack 2.
Video capture is done with a Pinnacle 510-USB peripheral,
Pinnacle driver 4.0.46.0.
Here's how I observe the problem: my input video is a color
bar pattern with burned-in time code. When I switch frame rates
from 29.97 fps to 1 fps, I see each and every frame appear in the
Media Encoder monitor window (as verified by looking at the
burned-in frame counter). However, only one 1 frame per second is
rendered. For example, I first see 01:00:00:01, then 1 second later
I see 01:00:00:02, then 1 second after that: 01:00:00:03, etc.
After several seconds, I then begin to see the burned-in time
code jumping in 1 second counts -- the expected behavior:
01:00:20:13, next second: 01:00:21:13, next second: 01:00:22:13,
etc.
The problem occurs when switching from any rate lower than my
source video rate of 29.97 fps, it's just that it's easier to
describe what happens at the lower 1 fps rate.

Inserting old swf into new fla with different frame rate

Hi, I'm trying to insert an old banner ad into a new Flash site. The problem is, the banner I made at 20 frames per second, and the Flash site is set to 41, so it literally plays the banner twice as fast. Any ideas as to what I can do about this? Thank you.

A few of them I may have the original source files on disk. Do you know what's the easiest way to transpose them to the higher frame rate?
For the ones I don't have, I should open the swf file in the new site and add a frame between each already existing frame?
Yes I imported the swf, I'm kind of just finding my way around Flash and I don't know how to load them dynamically. If I did load them dynamically, would they play at their original frame rate?

Understanding compositions with different frame rate

Hey everyone,
I am working with AVCHD footage with a frame rate of 25.
If it drop my footage into a new compostion after affects sets everything
up automatically.
I'd now like to what happens to my avchd clip if I change the frame rate
of my compostion from 25 to 24. What excatly happens to the frame
missing? Does AE just gets rid of it?
Does it make a difference if I just change my comp settings from 25 to 24
or if I drop my 25 comp into a new one with 24.
Thinking of it the other way around, if I change my frame rate from 25 to 50,
does that mean that AE doubles the frames of my files?
In general, does the changes have any impact on the speed of my footage?
I'm looking forward to your reply. Much appreciated.
Best,
Alex
PS: this count for Premier Pro aswell?

When you create a layer in a composition, and that layer is based on a video footage item, the composition checks at each composition frame to see (sample) the data from the footage item. If there isn't a single frame of data from the footage item that exactly lines up with the frame in the composition, then the composition samples from the footage frames on either side and does one of several things: It can either just pick one of the two frames, or it can just mix them together, or it can do something much smarter and try to reconstruct the image that would have existed between the two frames.What it does depends on what frame blending setting you're using.
When you're using a footage item that has a higher frame rate than your composition, and both frame rates are relatively high, you don't need to worry about this at all, as the default settings tend to work just fine.
To sum up, changing the frame rate of the composition just changes how often the composition samples the image data from the footage item. It does nothing to the footage item itslef and doesn't affect how fast the video from that footage item plays in a layer.
To interpret a footage item as being at another frame rate, or to conform a footage item to a frame rate, you have to use the Interpret Footage dialog box.

Problems editing ProRes 422 in FCPX– ? Frame rate issue?

I cannot edit video I import into FCPX except by using the Proxy media option in preferences.
I'm recording video from my HCX920 camcorder to Apple ProRes 422 format with Wirecast as the recording app during simultaneous live broadcasting.
The Wirecast encoding settings are set at: ProRes 422; 1920x1080; 29.97 fps for video and the audio is encoded as 24-bit integer; 48kHZ; 16-bit sample rate.
The video feed from the camera is 1080i at 59.94 fps.
The raw video file is identified as "Apple ProRes 422, Linear PCM" in Get Info. In QT 7 the FPS is listed as "29.81" Playing fps with the movie playing ranges from 28-30fps.
After I've imported the video to FCPX the "Project Properties" shows the video to be "1920x1080 | 59.94p". It seems that FCPX is importing the video recorded at 29.97 as if it were recorded at 59.97fps. Is FCPX transcoding my video to a higher frame rate?
I am unable to play the movie once it is placed into the timeline. It immediately stutters and shows the dropped frame warning. I am running FCPX on a Quad-Core Mac Pro with 20GB of RAM. The only way I can play the clip is by creating proxy media and choosing this in preferences.
What am I doing wrong? Any help will be greatly appreciated.
John

Kevin,
No, I was never able to get this problem worked out. It caused me to pull my hair out. When I compared the video quality of the ProRes output from Wirecast with the video recorded in AVHCD format on my camera's SDHC card the difference was dramatic. So I've stopped simultaneous ProRes recording in Wirecast and I now import the AVHCD material into FCPX from my camcorder's card.
I do, however, record the audio from my Wirecast broadcast and synch it with the video from the camera. The audio captured by the camera's built in mechanism is abysmally poor. This causes me more work but the final output is far superior to what I was getting from my Wirecast recordings regardless of format.
I wish I could help or offer more encouragement.
John

Preserve frame rate when loading one swf into another

Is there a way to preserve the frame rate of a swf when
loading it into another swf that plays at a higher frame rate. I'm
loading some flash ads that mostly run at around 12-15 frames a
second into a portfolio site that runs at around 40 frames per
second. All my ads play too fast. The link is:
www.dg8tal.com/portfolioidea.html
Thanks!

As far as I understand it, there is no option to override the
frame rate designated by the main movie you are loading into. The
SWF file you are loading always inherits the framerate of the SWF
you are loading it into. Here are some suggested work-arounds that
might help:
1) Lower the frame rate of the main movie on the website that
you are loading into.
2) Expand the timelines of the advertisements just for use in
your portfolio
3) Put your menu and thumbnails in one HTML frame that can
then load each item in another HTML frame above it. Since each SWF
would load on its own, the framerate of your main swf would not
matter. You would lose your nice resizing effect though unless you
did some more complicated integration with javascript I imagine.
I would recommend going with option 2, since that will take
the smallest amount of work while preserving your overall design.
However, with the faster framerate, your advertisements would have
difference performance characteristics that you'll need to assess.
I'm trying to think of more options, but these seem to be the
first things that come to mind.

Frame rate for camera does not match with AVI output

Hello,
I'm taking a video from a Basler A504K camera of well plate bottoms deflecting down. I have a frame rate indicator from the Vision Acquisition to see at what fps the camera is acquiring images, and I also have a frame rate controller at the IMAQ AVI Create VI.
The problem is when I set the frame rate at the Create VI. The higher I set the frame rate, the fewer frames it seems to take. For example when I play the videos on Windows Media Player, at 10fps, the video length is 60s. At 100fps, the video length is 6s. At 20fps, it's 30s, and at 50fps, it's 12s. Obviously, the video length decreasing by the factor by which I increase the fps. But since higher frames per second videos show a slower/longer videos, since they have more images to display per second?
I need to be able to see a slow increase and decrease in the well deflections smoothly. At high frame rates, the video goes by so fast that I cannot analyze the deflections. At low frame rates, the video is slower, but there are too many missing frames so the deflection is not smooth (ie. you see no deflection one second, and the next, you see the peak deflection without seeing the gradual increase in deflections). It is very hard to find an "ideal" frame rate, so I was wondering if there was another way to control the frame rate such that I have high fps, and longer video lengths?
I'm attaching my VI. The bottom loop is where all the Video and Camera controls are. The top loops is to control pressure gauge and valve (just ignore that loop)
Thank you,

Hi B.J. Kim,
The problem you're seeing with the fps and video length makes sense to me. If you keep the overall frame count constant and change only the rate of playback, then the video time will be indirectly proportional, as you have noticed. Just from simple math, it appears like you kept the video image at a constant of 600 total frames while changing the frame rate between 10, 20, 30fps, etc. If you're looking to have more resolution in you video, maybe you could increase the actual frame rate of acqusition from your camera. You may also try placing a small millisecond wait in your while loop to slow down execution speed.
