Setting video frame rate

Hi,
Are there someone had been able to control frame rate of video chating with actionscript or somthing else?
I have no preference which would be to set it in static or dynamic.
Thank you
Ono Keiji

you can use your camera and microphone when connected to Stratus. however, you can only publish your camera/microphone for direct connections (new NetStream(nc, NetStream.DIRECT_CONNECTIONS)), and subscribers must use the direct connect API to get the stream from you (new NetStream(nc, <your-peer-id>)). in this mode, your video/audio stream never goes to the server, but travels directly from you (the publisher) to the subscribers. that's the *only* mode that Stratus supports.
because your stream may be received by multiple peers, you must choose a bandwidth (and other encoding parameters) that is likely to fit through the path(s) between the publisher and subscriber(s). if the encoding parameters you've chosen exceed the bandwidth between publisher and subscriber, eventually frames will be dropped. also in bandwidth exhaustion situations, because audio is higher priority than video, you may see audio and video go out of sync at the publisher.
if you set a fixed frame rate and a bandwidth cap, then the encoder will vary the quality to fit within the parameters you've fixed.

How do I set the frame rate to 12fps on my video, and it not change randomly?

Hi, I imported a video layer from file then set the frame rate to 12fps, when I play the video it keeps changing the frame rate to random times. How do I keep it at 12fps

Click the windows start button, then right click on computer, this will bring up a window that will tell you how much ram your system has.
Also Start>Accessories>System Tools>System Information will give you all the details you need to know.
As for Codec, That is an abreviation for code/decode it tells windows how to code when saving a video and how to decode when playing a video. Most formats are wrappers (avi, wmv, mov, rt) Each of these have a codec that you can choose from when saving a video, that codec then must be installed on the users computer to see that same video. Most formats come with a basic number of codecs and the creator of the video can purchase other codecs that provide better feature set.
What the codec really does is takes the video and compresses it like a zip file then the user when playing require that codec to uncompress it.
So each codec has its own strength and weaknesses. Some can compress more making a smaller file and perhaps inturn removes more data to get that compression and therefore has a poorer quailty video (just an example)
I am sure you heard of a few codecs if you think about it. mpg, mp2, mp3, mp4, h.264 and so on. Mp3 is the only one I listed here that is for audio only. Yep thats right even audio uses codecs.

Video Frame rate problem.

Hi experts,
I am working with JMF to capture a video source and display it in a JInternalFrame.
I set the frame rate to 30fps, but when running the program I only have 1fps. If I set the LightWeightRenderer of the Manager to false, then I have 16fps (not the 30fps requested).
If I use JMStudio I get the 30fps.
Do you have any idea of what's going wrong ??
Your ideas are welcome.
Matthieu

Thanks for your answers.
In fact, I am capturing a video source coming from an echograph with a Miro PCTV video card (bt848).
My computer runs with WinXP on a PentiumIII 450Mhz, 256Mo of RAM, and a NVidia GeForce 2 GTS with 32Mo of RAM.
I obtained the following results:
     -> Using RGB, 640x480, 24bits, 30fps :the real frame rate is 3-4 fps.
     -> Using YUV, 640x480, 30fps: the frame rate reaches 15 fps.
     -> Using JMStudio I always get 30fps.
This frame rate is given by the video player.
I think that the problem is not linked to the hardware configuration but in the way the video is displayed in the application.
Indeed, I don't anderstand why JMstudio is able to give 30fps and my application only a few fps.
The main difference is that I display the video in a JInternalFrame and in a Frame. But even if I supress the Manager.LightWeightRenderer support results are a little better but I never reach the 30fps.
To build the video renderer I have used the MDIApp.java and JMFrame.java files given by Sun.
My question is what can do the difference? How can the Sun code be so performant ?
If you want more details on my code, I can put some piece of code on the forum.
Thanks to find a solution because I am going to go crazy !!!!

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,

Belkin Pre-N F5D8230-4 v2, slow video frame rate

After years of faithful service from my D-Link DI-713P, the wired-ethernet switch (to which my iMac was connected) stopped working. I bought a new Belkin Pre-N F5D8230-4 v2 to replace it, and both the wired and wireless connections work fine... except with iChat. I can get a connection (e.g. to appleu3test01), but the frame rate is painfully slow. Running through the router, I get <15fps, <70kbps. Connected directly to my DSL modem through PPPoE, I get 30fps, >700kpbs; same performance as with my old D-Link router before it croaked. This seems to me to be a clear indication that the problem is the router, not my iMac, the DSL modem, or the ISP (SBCGlobal.net).
Things I have tried to solve the problem.
1. Port mapping all the iChat TCP and UDP ports listed in numerous locations in this discussion group, Apple support, portforward.com, etc.
2. Enabling UPNP with and without the port mapping enabled.
3. Operating through DMZ.
4. Unbind SIP from port 5060 (see Ralph Johns' very helpful site: http://www.ralphjohnsuk.dsl.pipex.com/page4.html#_text). I was not able to telnet into the router (connection refused), and I couldn't find any SIP configuration on the web interface to the router, so I actually didn't get to try this. I don't have VoIP, and I'm not aware that SBC offers it, so I doubt that this is the problem.
5. Ensured that iChat ports are allowed in OS X firewall.
Any of these configurations enable me to make an iChat video connection, but all with slow frame rates.
One other bit of information that might be helpful to someone who understands all this a bit better than I is the entries that are generated in the Belkin firewall security log when I run iChat:
DoS log:
2005-10-16 08:17:59 [HOST Attack: UDP Flood] (UDP) LAN to WAN 192.168.2.2:16384->17.202.39.141:16384 [Drop]
2005-10-16 08:17:59 [HOST Attack: UDP Flood] (UDP) WAN to LAN 17.202.39.141:16384->71.131.221.23:32784 [Drop]
2005-2005-10-16 08:18:00 [HOST Attack: UDP Flood] (UDP) LAN to WAN 192.168.2.2:16386->17.202.39.141:16386 [Drop]
2005-10-16 08:18:00 [HOST Attack: UDP Flood] (UDP) WAN to LAN 17.202.39.141:16386->71.131.221.23:33811 [Drop]
It would seem that the firewall considers the iChat traffic on 16384 and 16386 to be denial-of-service attacks. Shouldn't the port mapping prevent this? If this were the only problem, wouldn't operating in DMZ avoid this problem?
I have not yet tried changing the firmware version of the router, in part because there seems to be some confusion about what the latest version is: web site lists 1.01.03 with a date of September 2005, but my installed version is 2.00.06. Apparently a version 1.01.04 was released but then retracted, and 1.01.03 is from January 2005, not September. Revision control does not seem to be Belkin's strong suit. Right now I have nothing to lose, so loading 1.01.03 may well be my next step.
Some configuration details:
iMac, PowerPC G4 (3.3), 1.25 GHz, 768 MB RAM, 167 MHz bus
OS: OS X 10.3.9 with all security updates as of 2005-10-16
connection method: SBCGlobal ADSL through Speedstream 5260 ADSL modem through Belkin FSD8230-4 router through ethernet to iMac
connection speed: 1214 kbps down, 306kpbs up
software: iChat 2.1 (v153)
camera: Canon ELURA70
Router info:
     Firmware Version 2.00.06
     Boot Version 1.00.00
     Hardware F5D8230-4 v2
Is anyone getting good performance with iChat and this model Belkin router? Any other clever configuration ideas to try?
- Fry -

Hi Ralph,
Thanks for the reply. I re-read your page on SIP and realize that it was a modem (not router) issue after I posted. Dohh! Thanks for being so polite.
I agree that the DoS seems like the key, and hopefully the specific security log messages will facilitate useful feedback from the Belkin tech support folks to whom I sent a copy of my post.
I tried turning on WAN Ping Blocking - no change. The System Settings tab allows me to set the password, date/time, and enable/disable of remote management, NAT, UPNP, and auto-update for the firmware. Of those I have only switched UPNP on and off. Unfortunately there is nothing on packet size settings anywhere that I could find.
I tossed the packaging for the router, so I may not be able to return it easily. If this is the case, and Belkin (or someone in the forum) doesn't come through with a solution, I was thinking of buying an inexpensive wired router to connect between the modem and the iMac, and also run the Belkin off of the wired router for wireless access. Are there well-known problems daisy-chaining routers like this?
The obvious alternative would be to sell the Belkin (to some non iChat user) and replace it with something known to work well with iChat. I read a recommendation for the Netgear DG834G in another posting, which could also take the place of my Speedstream modem (although there is nothing wrong with it). Any other recommendations from this wise community?
For the time being I am switching between the router routine tasks and direct-to-modem with PPPoE for iChat. Not elegant, not easy to teach to spouse, but it works.
Cheers,

IPad mini retina - native video frame rate

I'm trying to shoot 30fps HD video with my iPad mini (Retina). I was under the impression that the iPad mini's native video format is 30fps. But when I import my footage into iPhoto, it turns out to be only 24fps.
So - what's the Mini's correct native video format (including frame rate)? Is there an easy way to change the capture rate? Is there an app that allows capture at different frame rates?

Try this. Reset all settings. Settings>General>Reset>Reset all settings. You will not lose any data, but you will have to re enter all of the iPad preferred settings that you entered in the settings app.

Importing video Frame Rate Off???

I am importing video which was shot on a DVX 100 at 24p the image plays fine on my playback deck but when I Play the digitized footage in FC it appears to be in fast forward... Not sure if this is a Frame Rate Issue???

I don't understand. Did the captured clips playback fine in fcp last night? How did you digitize them? You need to either use the correct capture preset in fcp or modify an existing preset. If you're using another piece of software to capture, you gotta let us know this info.

Video frame rate change from video to video

HI all ,
when I use labview 2013 I found some strange in acquiring avi video
when I acquire video from my computer the fps change from video to another one
some video fps reach 800 fps and other reach 180 fps what is the problem

A lower frame rate is actually expected behavior if you are playing video through LabVIEW. This KB explains that LabVIEW analyzes the video one frame at a time and keeps it in the system memory on the CPU. This can result in slower frame rates during playback. If you would like to simply view video through your front panel, it may be a good idea to embed Windows Media Player in the VI through an ActiveX control.

Video frame rate issues

When I watch flash videos (mostly in hd and from youtube or gametrailers) in full screen, the frame rate becomes noticably slower. I have tried the 10.1 beta3 and this fixes the frame rate issue, but several times per video the image garbles. Everything runs fine outside of fullscreen. Otherwise I'm using Vista/Win7 64 bit with a 2.6 ghz Core 2 Duo, a radeon 4850 (latest drivers), and 2+ gigs of free memory. When running 10.1 without hardware acceleration or earlier versions with default settings my cpu usage never goes above 20% on each core. Does anyone know how to fix the image garblng or low framerates while in full screen?
Thank you in advance!

This is the tearing that I get with acceleration enabled

Video frame rate issue

I downloaded some clips from Gettyimages to put together a mock clip. Once I finished the clip I bought the clips from them and replaced the media in my timeline. My problem is that I can't afford to buy the 30fps videos and I'm stuck with the 15fps clips. Is there a way I can make footage look less choppy? Is there anyway I can adjust the FPS in the FCP timeline?

What? They sell 15fps clips for cheaper? I didn't think they sold anything other than full res. And they are an EXPENSIVE place to go. Is this a web clip deal of some sort?
Adjusting the frame rate won't make up frame information that isn't there. 15fps turned into 30fps will just show each frame twice. Frame Blending might help, but it also might make it look odd.

[SOLVED] Very poor video frame rate after upgrade

I'm relatively new to Arch, having been a Slackware user for many years (since Slack 3.5), so please treat me gently!!
I installed Arch about a month ago from the network and had everything running well, including Firefox 4.0. Today when I started the PC and ran Firefox, I received a message recommending that I install Firefox 4.0.1. I duly downloaded the Arch package for FF 4.0.1, but it wouldn't run, complaining that it couldn't load XPCOM. I searched through the Arch forums and found a suggestion to run Pacman -Syu to upgrade the system. This upgraded around 140 packages, including quite a few Xorg ones.
Now I find that watching any sort of video in Xorg (e.g., The BBC weather forecast in Firefox or BBC Iplayer, or even glxgears), the frame rate particularly at full-screen is abysmal, dropping as low as around 2 (two!) frames per second. Glxgears manages around 9 frames per second. Before today's system upgrade, glxgears achieved exactly 60 frames per second at any screen size and BBC video was smooth at full-screen.
I'm guessing that the problem is somewhere in an upgraded Xorg package, but I'm completely in the dark as to where to start looking. There are no obvious problems reported in /var/log/Xorg.0.log. I could post the content of this file if required, but it's huge and would make an extremely long post.
Please could someone offer me some guidance on where to start looking for the problem and how to fix it. The hardware I'm running on is Asrock 890FX deluxe 3 motherboard, Phenom-II 955 CPU, Asus 1Gb Radeon HD5570 video card. 'uname -a' reports that the kernel is 2.6.38-ARCH.
I hope I've posted this in the right forum. If not, please advise accordingly!
Thanks in advance for any clues!
Gerald.

The files in your /etc/X11/xorg.conf.d folder are the standard ones, so they should not be the problem.
I've looked in your xorg.log, and while the problem is not clear immediately, you got several (WW) and (EE) messages in it.
[ 27.795] (WW) The directory "/usr/share/fonts/OTF/" does not exist.
[ 27.795] Entry deleted from font path.
[ 27.836] (WW) `fonts.dir' not found (or not valid) in "/usr/share/fonts/75dpi/".
[ 27.836] Entry deleted from font path.
[ 27.836] (Run 'mkfontdir' on "/usr/share/fonts/75dpi/").
these are safe to ignore
[ 27.837] (WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)
without acpid installed, your monitor probably won't be blanked when you're system is inactive for a while, but otherwise this should not be a problems.
(EE) Failed to load module "vesa" (module does not exist, 0)
(EE) Failed to load module "fbdev" (module does not exist, 0)
vesa and fbdev are intended as fallback options, it's better to install them.

These lines may have to do with your problem, but i don't know what they mean.

Video frame rates

Is therestill no support for importing at 1080/50p and editing at this frame rate in iMovie'11? I believe FCPX now has it.

You asked this question on the FCE forum. I answered you there. Which application are you using?

Mixed frame rate video clips on the same Blu-ray disc

Before I go into the detail, this actually isn’t an issue for me, but more of a finding the answer to a different question, so please bear with me.
To explain: I live in the UK, and I’m forever challenged by the different native video frame rates imposed by the PAL and NTSC standards. Every consumer camcorder I’ve ever seen only produces HD output (1920 x 1080) at either 50 fields/second interlaced, or 25 (sometimes 50) frames/second progressive. Some action cameras (Go Pro) I possess allow me to record at 30fps progressive, in full HD, which for fast movement is simply better. This in itself is not really a problem, but I use other software (all USA sourced) for video production whose best results are only visible when the finished HD output is 1080/60i.
Having mixed frame rate video is a real problem for the DVD standard, but no so much for Blu-ray. Indeed Adobe Encore neatly gets around this problem, so I can actually author a Blu-ray disc which contains full HD video clips that may be either 50i or 60i. Both types of video exist on the same disc, and when played back through a Blu-ray player/TV combination, the resultant video clips are shown correctly. Player and TV switch seamlessly to the correct setting to handle the video content. So, I have a solution to my problem, but at the same time, a question I can’t find an answer to, which is this:
Does the Blu-ray specification allow video clips of different native frame rates (i.e. 25fps and 30fps) assuming the resolution is the same, to co-exist on the same Blu-ray disc as a supported feature?
It works, but I can’t find one shred of information that says what I’m doing is supported.
Comments are most welcome.
Regards,
Steve

Encore requires you to specify the project type as PAL or NTSC (whether you start it as Bluray or DVD), and does not allow you to change it later. Also, if you try to create a transcode type for PAL in an NTSC project you cannot get to the 25 fps setting (and therefore, I think, cannot do it).
But if you import a Bluray legal 25i file to an NTSC project, it is happily added.
DVD player conventional wisdom is that PAL players handle NTSC disks, but NTSC players do not generally handle PAL disks. I never quite understood why the TVs were not more of the issue. Do Bluray players even differentiate between PAL and NTSC?
Even if the player will handle PAL, the TV may well not do so - so there is more going on.
NTSC uses (generally) 60Hz systems whereas PAL is 50Hz hence the problem.
Do not try to mix standards as it will not be allowed - however, multiple frame rates are allowed as long as they are within spec for that TV standard.
They are best avoided though - otherwise you run a very real chance of serious asset truncation as the TV display switches between different resolutions & frame rates.

Need to set my own frame rate preset

Where in Final Cut Express can I type in my own frame rate preset? I'm importing YouTube video at 640x480.
Message was edited by: rsherid

I scrapped Express and installed Final Cut Pro HD. I set the frame rate sequence preset at 640x480 (i.e., the frame rate of all my imported video) and it's still forcing me to render it. Could someone kindly walk me through the setup (Easy Setup, Audio/Video settings, etc.) so I don't have to keep rendering 640x480 video? It'd be greatly appreciated.

Setting jmf bit rate/ frame rate

Hi!!
I'm with some problems configuring my video settings.
Where should I go to set the frame rate od my video streaming?
I'm using H263 format, and the frame rate is variable and I want to set it for a lower value so that my video streaming can be more "fluid".
Should I go to Control Panel of the Windows and change there at Multimedia codecs?
Regards from Portugal

Here You have sample how to specify frame rate (in this exampke - 10f). I use here data from video caprure and create processor with ProcessorModel. Then I send it by network (RAW_RTP - in this dimentions it id H263)
VideoFormat vf = null;
Dimension size = new Dimension(176, 144);
vf = new VideoFormat("RGB", size, Format.NOT_SPECIFIED, null, 10f);
Format [] formats = new Format[] { vf };
ContentDescriptor cd = new ContentDescriptor(ContentDescriptor.RAW_RTP);
ProcessorModel proc_mod = new ProcessorModel(dsCapt, formats, cd);
dsCapt is DataSource from my capture device.
for details look: JVidCap file from : http://java.sun.com/products/java-media/jmf/2.1.1/solutions/JVidCap.html
