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.

  • JMF Video Player Frame Rate comes down to zero

    Hi
    I am working on video Player using jmf. I am playing .mov file in the Applet. The appled have been signed and this part is working fine.
    I am able to get the video from server to the client using signed applet. But the problem now i am facing is that after few seconds of video download the frame rate and bit rate both comes down to Zero and the movie stops playing. I am using .mov extension with approximately 2-8 MB size of video.
    As i feels problem is coming with the http protocol. Because while playing the local video file with the same code it is performing well.

    This blog is written by one of the principle guys who writes the Flash plug-in.

  • JMF Dimension and frame rate

    Why I'm not getting success when I try to determinate the Dimension and frame rate of the VideoFormat passing the parameters to the constructor ?
    processor.setContentDescriptor(new FileTypeDescriptor(FileTypeDescriptor.MSVIDEO));
    TrackControl tracks[] = processor.getTrackControls();
    float rate = Math.abs(Float.parseFloat(jcbQuadrosSegundo.getSelectedItem().toString()));
    VideoFormat vf = new VideoFormat(VideoFormat.H263, getTamanho(), Format.NOT_SPECIFIED, Format.byteArray, rate);
    FormatControl fc = (FormatControl) tracks[0];
    Format f = fc.setFormat(vf);
    tracks[0].setEnabled(false);
    processor.realize();
    ...getTamanho() return an Dimension that indicates de width and height.
    jcbQuadrosSegundo is an JComboBox.
    Thanks !!

    Skype is generally on autopilot.  I believe 1920x1080 (1080p) would be the max resolution as far as I can recall.  If the Internet connection isn't good enough at both ends, it will drop down to the resolution the call can handle.  The max resolution of the mobile device would be dependent on the hardware and the Skype client.  The webcam resolution compatibility is sometimes dependent on the version Skype.  Some people achieve better compatibility with the desktop version 6.1 vs the current 6.3.  If you want to monitor the resolution you can view the call technical info.  It will display the current resolution of both feeds and other call stats.
    This external site has some good info on it, though a bit dated, it should provide some insight.  I'm not sure if any of the mobile resolutions have been updated greater than 320x240.

  • How to tell the Spec's of FLV video? - bit rate, frame rate, etc.

    Flash CS3 on Windows XP PC..
    How can I determine the spec's of an existing FLV file?
    1 - Video bitrate
    2 - Video frame rate
    3 - Audio bitrate
    4 - Audio sample rate
    etc
    Thanks for any help.

    Must you "impor" the FLV file into Flash to see the "metadata" property?
    If so how?

  • Quick Notation Question - Data Rates/Frame Rates/Interlacing

    Finally upgraded to a decent prosumer camera and I'm trying to decipher what the manual is telling me about the many different formats it shoots and and the associated options.  I keep seeing things like "There are two basic shooting modes: 720p and 1080i/p.", which I'm finding confusing.  In my understanding, the "p" in 720p means progressive video and the "i" in 1080i means interlaced.  So what do I make of 1080i/p?
    On top of this, my camera shoots in "native" mode, which drops duplicate frames used in "over 60" formats.  This will give me variations in the notation like:
    720/24pN
    720p Native 60 fps
    1080i/24p
    1080/24PN
    Can someone give me a quick primer about frame rate vs data rate and explain how to read these notations?  I'd appreciate it quite a bit.
    Thanks!

    There are so many cameras, capable of so many different formats that providing a manufacturer and model could be helpful in this discussion.
    Jim's answer is absolutely correct but I'm going to re-state for clarification.
    The i/p designation means you can chose to record as interlaced or progressive for a given resolution.
    It sounds like your camera is designed to "capture" images at 60 frames per second, selecting "native" mode means extra frames are deleted and only the desired frames, based on frame rate setting, are recorded to memory. The advantage of "native" @ 24fps is you save space on your memory card. The advantage of NOT using "native" mode is that all 60 frames per second are recorded, but the file metedata tells playback software to only show the frames needed for the specified frame rate (i.e. 24). Since all 60 frames per second are recorded, you use more memory but you also have the option of retrieving all the those frames, if you so desire, at a later time (i.e. for smoother slo-mo).
    To be honest I don't know what your spec of 1080i/24p means. If that is truly an option then I would guess it means it will record a 24p image but the metedata would indicate the file should playback at 30fps interlaced by adding the proper 3:2 pulldown. This would give you that "film" look in a broadcast compatible format.
    For the most part, you don't want use use any interlaced settings. Very few display devices still in use can properly display interlaced images. Interlacing is only required in some broadcast specifications.
    To answer the second part of your question;
    Frame rates are an indication of how many times the moving image is captured over a given period (per second). Higher frame rates means smoother, more "real life" motion. Data rates can generally be considered an indication of image or audio quality. Higher levels of compression result in lower data rates and (generally) lower quality. If squeezing more hours of footage on fewer memory cards is more important than getting the best image quality, choose a lower data rate. Higher frame rates (more images per second) inherently require a higher data rate to retain the same quality as fewer frames at a lower data rate.

  • Getting data rate, frame rate for encoded clips

    In quicktime movie info gives frame rate and lots of great

    this is so hard to find.

    A DVD is MUCH lower than the resolution of your new camera... the picture in the next link shows the relative sizes... your DVD is never going to look as good as a BluRay, which is what is needed to have HD video

  • Setting frame rate

    I have some ProRes HQ files that are set as 30fps but the contents are really 24fps or 18fps. What is the best way to get the footage set to the correct frame rate?
    These are actually 8mm and super8 films that were captured frame by frame and the captured files were tagged as 30fps, not the real frame rate.
    Any help would be greatly appreciated!
    Tim

    I was able to create an image sequence and export an 18fps clip using AE. Unfortunately, FCP doesn't seem to allow a sequence with 18fps setting. If I put the clip into a sequence with a higher frame rate, FCP just generates an odd cadence -- AABBCDDEEFGGHHI (or similar for 30fps seq) and doesn't allow me to have frame accurate edits (unless I run through the cadence to find the break.) The bigger issue is I would rather have a smoother output than the odd cadence.
    Is there a way to get FCP to generate an 18fps sequence that I can edit in and export from? Or maybe I need to switch to Premier Pro? I'll retime in Shake after the edits since it will generate interpolated frames and create a smoother final output.

  • Help with sequence settings in final cut for project with 2 different frame rates.

    I really need help with this one! I finished editing a wedding video and realized after exporting that it was filmed in two different frame rates. This has happened before but I converted the footage to match and fixed the problem. In this case, the footage is part 30fps and part 60fps. The majority of it was filmed in 30fps. I cannot convert the 60 to 30 without the slow motion effect which I do not need so I have to find a way to burn this to a DVD without it looking messed up! The video was shot with two Canon 7ds if that helps anything. The first sequence I set at 29.97 and exported as a quicktime movie and all the footage filmed in 60 looked perfect and the footage in 30 looked jittery. Then I tried the sequence at 59.97 and it switched. The footage filmed at 30 looked good and the 60 was cropped in. I am so confused! Any advice or suggestions would be greatly appreciated!!

    Thanks for your help Michael! The frame rates are 29.97 1920 x 1080 and 59.94 1280 x 720. I did a control click on the clips in final cut and viewed the item properties/format to find this info. The Canon 7d is a DSLR but we use it for video. As for my workflow, the first thing I do is import the footage onto my computer and then drag the clips into mpeg streamclip. I choose apple prores 422 and uncheck the interlaced box. Once this is done I import the .mov files into final cut. The sequence automatically sets itself to whatever clip I drag in first so it originally set as 29.97. When I finished editing wedding video, I export it to a quicktime movie and choose whatever settings match the sequence, in this case apple prores 422 1920 x 1080 30p. Once that is done I use iDVD to burn the discs.
    I knew something was wrong when I watched the quicktime movie and all the 30fps footage was jittery and most of the cross dissolves looked strange. That's when I figured out the footage was at two different frame rates. What I don't understand is why whatever the sequence is set at in final cut, the clips of the opposite frame rate look right but the clips set at the matching frame rate don't???

  • Mixing Frame Rates and Creating Old Film Look?

    Hello, I'm working with AVCHD footage which is 59.94 fps and have made my sequence settings at this frame rate. I've dragged in a few clips 23.98fps, 24fps, 25fps and 29.97fps, I'm attempting to give it a old film look so was going to render out at 14 fps as this is what 8mm is filmed at, I've never worked with mixed rates so any advice as to whether this is going to work? Should I have my sequence setting at my highest frame rate and the majority of the video is 59.94fps? would it work exporting at 14 or 16 fps?  

    I've never worked with mixed frame rates, but for the old film look, I like the Posterize Time effect set to 18 (one of the two standards for Super 8 that my camera had) and use Magic Bullet Misfire.

  • Intro Movie at slower frame rate when uploaded

    The intro movie I created for my photography site plays too
    slow when uploaded, thus making the music finish long before the
    animation is done; needless to say, this makes for a very tacky
    intro!
    Does anybody know what I'm doing wrong?
    Thanks

    The frame rate is always set to the "prefered" frame rate.
    The actual frame rate depends on the server, the speed and the size
    of the swf file. The best you can do is to fully optomise the
    images before you import them into flash.
    As you are into photography I can understand the need for
    good quality images thefore it is a case of what do you prefer?
    Good images or good speed!

  • Frame rate option is greyed out

    How do I change the frame rate from 60fps to 30fps? The frame rate option is greyed out not allowing to make the change. I am importing from FCP.

    One way is to click the Plus sigm at the bottom of the Settings pane. Select New Setting and then a format category (example, QuickTime Movie) and create your custom setting with the desired frame rate.

  • How to set the Codec, Frame rate, Bit rate, and Resolution for iMovie 10.0.5

    To upload a video to Vimeo, I need to be able to set the codec, frame rate, bit rate and resolution to make sure the file is compressed to under 500 MB. Where in iMovie 10.0.5 am I given the option to adjust these settings?
    Thank you!

    Another question is in continuous mode, NI DAQmx uses Samples per channel to determine the buffer size. But according to the website you specified, it says if the acquisition is continuous (sample mode on the DAQmx Timing.vi is set to Continuous Samples), NI-DAQmx will allocate a buffer according to the following table. And for sample rate between 100 - 10,000 S/s, the buffer size is 10 kS. So if I set the sample rate to be 5000 S/s, and set the Samples per channel to be 20000, then what exactly the buffer size is? 20 kS or 10 kS?
    Thanks.

  • With Canon XF100, canfootage shot at a higher bit/frame rate than other footage be edited together?

    If you start recording footage at the highest quality bit/frame rate for a project, then realize it's going to take forever to render and eat up a lot of space, can that footage be edited with footage shot at a lower bit/frame rate? Or will there be an obvious difference in quality? Trying to decide if it's best to switch rates now...
    What would the best bit/frame rate setting be to shoot high-definition footage? 
    Thanks!

    Were you shooting on the Panasonic HVX-200 onto P2 cards in 720pn mode?
    Yes, that's correct.
    you should still make a DVD and watch the movie on a TV
    I will do that; thanks for the advice.
    if you are having these problems on your computer, there's always a chance that your client will have problems showing the file on the unknown computers
    That has been a big part of my cause for concern. My friend (the one I'm working with on this project, who owns the equipment we're using) would prefer to burn it to a Blu-ray disc, but unfortunately we don't have access to a Blu-ray burner. So I'm thinking we should provide it as both a DVD and as a QuickTime file, to cover as many bases as possible.
    Thanks again for your patience with novice questions. I've looked for books on these kinds of things, but everything I've found seems to either be written at the extreme beginner level ("this is how you upload video onto your computer"), or the extreme advanced level. Perhaps I haven't been looking in the right places; if you can suggest some good reading materials on this kind of thing, that would be great.

  • Adjust bit/frame rates?

    I have the NX Ultra camera and I want to change the quality of the image to a lower quality. Right now the camera is set at a frame rate of 30, a bit rate of 870, and a resolution of 320x240. I've tried going to advanced settings and lowering the quality under JPeg quality options, but it hasn't helped enough. I'd like the frame rate down to 5 and the bit rate down to 300. Any ideas?

    I was under the impression that MPEG-2 encoder came with Compressor 1. I never used Compressor until I upgraded to FCS and started using (or rather trying to use) Compressor 2.
    Check out the link below:

  • Low frame rate even with high bit rate

    I am using a Logitech QuickCam Pro for Notebooks (the model that supports UVC per Logitech's website) with a new Mac Pro and iChat. Whether I do a video iChat over the internet or one within my internal network, the fps per the connection doctor of my camera is about 6 fps, even if the bit rate is over 2000 (which is what is was when I did the internal network chat). I can't find any setting where I can increase the fps rate, I can only increase the bit rate in the camera preferences in iChat.
    The camera is capable of up to 30 fps and when I do a video recording with it in QuickTime Pro and play it back, QuickTime Pro shows the frame rate as 30. So the camera is connected properly and is working properly. Any ideas on how to get the fps up to 15 in iChat (which seems to be the maximum, per the MacBook Pro I used for my internet network test above)? Thank you.

    Thanks for the reply, Tony. Changing the bit rate limit to 500 did not cause the frame rate to change. On my test with my internal network if I had the limit set to none then bit rate was over 2000 but frame rate was only 5-6. When I limited the bit rate to 500 it dropped while the frame rate remained unchanged a 5-6 fps.
    When I was doing an internet chat I also changed the bit rate limit to be none, 500, or 1Mbps to see what would happen and the connection doctor showed my frame rate staying at 5-6 and my bit rate staying below 100 (so changing the maximum bit rate setting made no difference). Meanwhile, the person I was chatting with had a frame rate of 15 and a bit rate of about 250.
    I'm on a cable modem just like the person I was doing the internet chat with, so I guess the problem is something to do with iChat and my Logitech web cam, not my internet connection.
