FrameRateControl to change frame rate

I have created code that runs on both Linux and windows.
The purpose of this code is to change the frame rate of capture device(webcam).
I have created a processor, and player, get FrameRateControl, and use setFrameRate(5.0f).
I have tried multiple combinations, just processor, just player, etc. and tried setting frame rate to different number, without success.
stopping processor, stopping player, setting frame rate, the starting again, and frame rate does not change!!
I have even created a ProcessorModel, with one format, specified frame rate, but still doesn't change.
Any one have ideas, or suggestions????
I can post code, but has lots of comments, and is messy, just a warning.

tcp packets are always waiting for ack thats why performance are low - and the error correction mechanizem ensuring data will reach his destination is also not helping you -
you will have to use udp - (rtp/udp)

I want to play video on my computer to make some analysis to frames,the problem that I face ,I can't change video frame rate using labview,but I can change frame rate to the video out of labview using some program

HI All
I want to play video on my computer to make some analysis to it's frames,the problem that I face ,I can't change video frame rate using labview,but I can change frame rate to the video out of labview using some program .
I used IMAQ AVI Read Frame VI
for example I have avi video It's frame rate is 25 fbs ,my image processing code is very fast that can process more 25 fbs,so I want to accelerate video acquisition

Hi abdelhady,
I looked into this further, and reading an AVI file into LabVIEW faster than its frames per second won't be possible. LabVIEW could read in frames faster than 25fps, but because it will be pulling the available frame at that point in time this would just give you duplicate frames. If you want to be able to read in frames at faster than 25fps, you would need to speed up your AVI file before reading into LabVIEW.
There's a good shipping example to show how to read in from an AVI file, "Read AVI File.vi". You'll notice that they add timing to make sure that the while loop runs at the right speed to match up with the frames per second of the file being read. This is to make sure you're not reading duplicate frames.
Thank you,

Support MIDI and dynamic change FRAME RATE

What MACROMEDIA says about support by FLASH, midi files and
dynamic change FRAME RATE of the movie?
this is two nuances that does not suffice me.
And what about macromedia FLASH 9? When it comes?

For dimension changing use something like this (is a part of a bash script for video edition so ...) :
# Le quitamos el over-scan al ancho. OJO!! debe seguir siendo MULTIPLO de OCHO
WIDTH_SCALED=$(($OUTPUT_V_WIDTH-$OUTPUT_OVS*8)) #multiplicamos el overscan por 8(4 pixeles a cada lado)
# Obtenemos relacion de aspecto de forma mas precisa
if [ "$OUTPUT_V_ASPECT" == "1.7777" ]; then # formato panoramico
ASPECT_PRECISE=`echo "16/9"| bc -l`
else
ASPECT_PRECISE=`echo "4/3"| bc -l` # y el formato normal
fi
HEIGHT_SCALED=`echo "(${INPUT_V_HEIGHT}*${OUTPUT_V_HEIGHT}*${ASPECT_PRECISE})/${INPUT_V_WIDTH}"| bc -l`
# Necesito que el alto sea MULTIPLO DE CUATRO para que la longitud del PADDING sea PAR y simplificar el codigo... introduzco un error de 3.999999 pixels (en el peor de los casos)
HEIGHT_SCALED=$((`echo "scale=0 ; $HEIGHT_SCALED/4"| bc -l`*4))
# Calculo el Padding
OUTPUT_V_PAD_WIDTH=$(($OUTPUT_OVS*4))
OUTPUT_V_PAD_HEIGHT=`echo "scale=0 ; ($OUTPUT_V_HEIGHT-$HEIGHT_SCALED)/2"| bc -l`
Don't bother about the comments . Is spanish .
What you want is :
HEIGHT_SCALED=`echo "(${INPUT_V_HEIGHT}*${OUTPUT_V_HEIGHT}*${ASPECT_PRECISE})/${INPUT_V_WIDTH}"| bc -l`
About frame rate - this is video edition and i think you can not do this in java . Is more complicated than a simple calc . Under linux i'm using ffmpeg to change fps and encode from avi to mpeg2 .

Changing frame rate when exporting from iMovie '09 using quicktime has no impact on duration. Why?

Changing frame rate when exporting from iMovie '09 using quicktime has no impact on duration. Why?
I have a file created by digitizing an 8mm film at a rate of 24 fps. I would like to create a downloaded movie at a frame rate of 15 fps. The Export using Quicktime option seems to provide that capability but the resulting file has the same duration as the original 24 fps file. How can I get the exported movie to be slowed down?

joegez,
There is a feature you can use to slow down the video. In the project, move the mouse pointer over the clip, then click the gear icon. That brings up the Inspector. Click the Clip tab. Then you will see a feature there called Speed. Move the slider to the left to slow down the clip. Or you can enter a percentage in the box on the right.
Hope this solves the problem for you.

Audio out of sync after changing frame rate

Hello
I just changed frame rate from 23.976fps to 24fps inside sequence setting, and the audio is out of sync in timeline. I can certainly manually right click mouse and choose slip into sync, but it's a tedious job. Anyone knows why and quick solution?

Want to change frame rate, help, please !!

hi all,
i want to know whether, jmf does provide any support for changing the frame rate ? is there any ways by which one can change the framerate, of a live captured video ?
i came across one class "FrameRateControl" in jmf, tried it, but wasn't successful in changing the frame rate. plz help me guys.
if u have came across, when doing live capturing using jmstudio, we can change the frame rate. can we do that in our programs tooo.
please someone, wew64, watergad.......... help me out..........,
thanks for ur help.
niraj.

the code is here and it is working on windows, but the framerate could not be changed on linux. it keeps saying rcFormat is null on linux. Then I try to change the framerate with JMStudio, it doest not make any difference as well, it seems keep playing the video with preferred frame rate as well. Any ideas?

How to export a flash project with a changing frame rate to a video

I have a Flash project that is a series of roughly 1000 images. The result of the images is a simple animation, and there is music imported on a separate layer.
There are moments in the music that I wanted to line up with certain frame changes, and there are sections of the music that I wanted to match up with a faster (double-time) frame rate.
I used this code in several places in the a code layer:
stage.frameRate = x;
The result is exactly what I want in SWF -- the animation speeds up and slows down at the exact right moments to match up with the music track, but it seems like it's just not possible to export this variable frame rate project to a video file?
According to the accepted answer on this post: http://forums.adobe.com/message/4019538, it seems that:
The export function in Flash Pro doesn't transcribe *frames*, rather it plays the Flash animation and records it like a camcorder
If that's true, then I would think there is a way to record a variable frame rate project into a video -- does anybody know if this is possible?

That or Premiere would both get the job done. After Effects might be more desirable as it has a feature called Time Remapping (right-click on the video layer, Time->Enable Time Remapping). You can add keyframes to any point in a video and then drag them around to speed up or slow down the video. That'll allow for very precise tweaks.
Finally all I'd suggest is when you jump into your next project, make a quick dummy test project to see if the software you're using is easily capable of producing what you want. It'll solve the headache of completing the project only to land where you are now. Now you know Flash won't play nicely with scripts and Export Movie. If your desired end result was always a video I'd probably use video editing software to make the video. There's some free stuff out there if you really look, but no, it won't be as nice as After Effects or Premiere by any stretch. Although when you see how amazing After Effects is, you'll probably want to buy it .

Can't Change Frame Rate in Properties

To change project properties in FCPX you click the wrench icon, which brings up a window to select 720p, 1080p, etc as well as frame rate. The problem is, there are no options in the dropdown for the frame rate in all of my projects, it chooses one automatically (seemingly arbitrarily) and you can't change it.
I thought that when the progam says it would detect the properties of the first clip and adjust the project properties to match, it would actually do that (maybe I should have known better). So I imported my standard 1080p 29.97fps footage from my Canon 7D and then FCPX automatically set the project properties to...720p at 24fps. Curious, no? No problem, I thought, I'll just go to Project Properties and manually correct FCPX. But it was not to be, as FCPX had decided to give me only one option in the frame rate selection: 24p. But no, I thought, I would very much like my properties to be 29.97 so as to match my footage. But FCPX did not agree with this, and would not change its mind.
Has anyone found a solution to this?
Do any pros still use Final Cut Pro?
Thanks,
Kurtis

It may be possible that a .jpg was the first thing in the project, which may explain the seemingly random properties (why wouldn't they just make it default to a more common setting like 1080p 29.97?) but I digress.
And it's a very stupid move to revoke the ability to change project properties while clips are in the project, that makes no sense.
I'm begining to think that Apple has really failed with this new version of Final Cut; and I've been using Final Cut for years. I am debating switching to Premiere, but I will give FCP X a bit more time to redeem itself.

HP Pavilion Slimline s5-1414 Accidentally changed frame rate.

Hi I'm new to this computer got it earlier in the year but never reaally tried it till now. My problem is that I changed the framerate from 60 to 120 fps and now i have no video. How do i fix this? I tried 2 different monitors one which is a pretty old one and the other was an Lg tv which states invalid format. the monitors also seem to have not worked while I'm starting up the computer what should I do to fix this?

Hi phz19,
Welcome to the HP Community! Are you referring about the refresh rate on your monitor? Frame rate is something that you can't really modify directly other then changing some settings which will effect it but you can change the refresh rate directly. Do you get anything on the screen at all when you turn on the Pavilion or does it just stay blank?

Change Frame Rate in Adobe Presenter

I have a Flash File that runs with 12 Frames Per second and I need to integrate this with Adobe Presenter. The Frame Rate for Adobe Presenter is 30 Frames Per Second. Here is where I am facing an issue.
Is there a way to change the frame rate for Adobe Presenter??
Thanks in advance

Nope. Unless you want to get into reconfiguring the viewer.swf and other associated swf files, you're pretty much stuck w/ the 30fps setting.

Change frame rate with no slowdown (Premiere Pro)

Hello, I am making a project and need to re-create a film in the style of a silent film, the most common frame rate for silent film is 16 fps. Is there anyway in the post production stage to change the frame rate of the video to 16 from 29.97 without making the clip longer?

See if you can get the look you want by experimenting with the Posterize Time effect. Leave the frame rate alone.
Cheers,
Jeff

Change frame rate on an AC3 files?

I've been given two NTSC (23.98 fps) .ac3 files (5.1 Dolby Digital EX and 6.1 DTS-ES) that I need to use in a PAL 25fps project. Any suggestions as to how to change the frame rate to match my PAL encodes?

You shouldn't have to change the 'frame rate' of your .ac3 sound files. Both PAL & NTSC video use the same sound formats. The only problem you might run into is if you changed the duration of the video when you did the video conversion. Hint - keep the durations the same.
Have you have changed the duration of your video versions? If so then start by decoding your .ac3s and then running them through a 'time-strectching' program before re-encoding them to .ac3. Not very elegant I'm afraid.

Im editing on a PC

1080i59.94 is still 30fps, running at 29.97. The "i" means INTERLACED, and then the number following that refers to FIELDS per second, not frames. 2 fields per frame, so 60 FIELDS per second...30 FRAMES per second.
And don't worry, if your footage is progressive, and you output a 1080i.59.94 file...both fields in the frame will be the same...It'll still be progressive.

HOW DO I CHANGE FRAME RATE IN iMOVIE 10.0.5?

WHERE IS THE OPTION TO CHANGE THE FRAME RATE OF A VIDEO IN iMOVIE 10.0.5? I JUST CAN NOT FIND IT, IT USED TO BE ON THE BAR IN THE OPTION OF PROJECT PROPERTIES BUT IT IS NOT THERE ANYMORE, PLEASE HELP.

The DV specification is to use drop frame TC. Unless you have a camera that's switchable all DV NTSC will be drop frame, which is why FCE works in drop frame. This is not a function you can switch in FCE. You would need to work with Final Cut Pro to get this functionality.

PrE 9.0 wont let me share as H.264 1280x720p 29.97 fps - keeps changing frame rate

As the title says I am unable to create an export with the following settings:
H.264
1280x720p
29.97 (or 30, neither possible) fps
I have tried editing the existing H.264 presets but the following happens:
I go into Share > Computer > MPEG and select the Preset "H.264 1440x1080i 30" then hit the "Advanced" button.
All I want is to change the resolution to match my project size, 1280x720 which I do - but then something happens
As soon as I change "Frame Dimensions (pixels)" to 1280x720, the fps is automatically changed to 59.94 and when I click the dropdown box for the frame rate, I can only pick the following:
23.976
24
59.94
Automatic (based on source)
Since I can't pick 30 or 29.97 I tried picking Automatic but that sets it to 23.976 - even though it clearly states that my source is at 29.97 fps...
At this point I don't really know what else to try and any help is appreciated.
Thanks
EDIT: Just thought I'd also mention that the source is from a GoPro Hero HD cam which shoots in 1280x720 H.264 AVC so I did select "NTSC AVCHD LITE 720p30" as the project profile
EDIT2: Found Bill Hunt's premade profiles for the GoPro and Premiere Pro. Trying them out right now and it seems to be working. But I still cannot create a profile with 29.97 fps at 1280x720 myself

With certain file formats and codecs, you will be limited in the configuration of size or frame rate. It sounds like the output format you've selected is one of them.
Try going to Share/Computer/MOV and see if that makes a difference.
