Bad webcam frame rate

I had this problem with my PC and hoped it would go away with the Mac, but it hasn't so any suggestions would be welcome. If I use MSN/Yahoo/Whatever to do a video chat with my mates, I receive their webcam pictures nice and smooth, but outgoing I seem to be sending about 1 frame per second. I'm on 1 meg broadband, and things like uploading emails seem to be plenty fast enough, so I'm a little confused. I'm using a wireless connection to a Netgear DG834 router if it makes any difference.
Matt.

One thing that always helps with wireless connections is:
1. Go to System Preferences > Network
2. Choose "Network Port Configurations" from "Show" pull-down menu
3. Drag AirPort to the top of the list (make sure it stays checked)
4. Click "Apply Now"
After doing this, try quitting & relaunching iChat (or whatever application you're using). If that doesn't help you could just test with a wired connection and see if it's any better. Chances are if you had the issue with your PC and you had the same internet connection, that's probably the cause.
good luck

Webcam frame rate, netStream frame rate, flv framerate

I'm recording Webcam to FMS 3.5 but when I play the recorded video from FMS it's choppy. I have set the camera.fps to 30 but when I trace out the currentFPS for camera it's variable and usually falls between 20 and 30. However when I play the recorded video, netStream's currentFPS returns a lower value, something closer to 10. So my question is, 1) why currentFPS of netStream is not the same as Camera's? 2) What's the actual frame rate of the recorded video (not the netStream, but FLV's)?
I've setup a test page which shows currentFPS of camera during recording as well as netStream's currentFPS during playing of recorded video from FMS:

[SE_0208] - It might be because of latency or some other reason that your frames are dropped and hence lower FPS is reported. To the first thing which you mention about camera settings, its not mandatory that when you set camera FPS to 30, you will get encoding rate of 30 FPS, it would depend upon data as well as your camera, some webcams don't support beyond certain FPS.
2) What's the actual frame rate of the recorded video (not the netStream, but FLV's)?
[SE_0208] - If you are talking about what is reported when metadata is triggered then answer is encoding setting which your publisher uses.

Does any know, what the frame rate is for the Creative WebCam NX Ultra

If you check the specifications, for this webcam. It's listed running 640x480, 320x240, 352x288, and 60x20 resolutions. What is the frame rate? If I run this webcam at 640*480 resolution.
thanks

See I knew it! Why can't they make the 30fps at 640*480, thanks guys. Is 5 fps a noticable difference, or what?

Quick Time Screen recording really choppy/ bad frame rate.

So when i record my screen using other programs everything is smooth and the video moves at the same speed as real time, but when i record using Quick time then the video is very laggy and the frame rate is really bad and things are just jumping around a lot.
Is Quck Time just not capable of Screen recording complex things? is it only capable of recording microsoft word? lol.
If someone can hep me use Qucik time to record me screen then that would be great, cause with the way it is now there simply is no point to using it at all cause it doesnt record the screen very well, it just lags and everything jumps around to much. Its like watching a slide show where the pictures change every 2 sec rather than a video.

Hello justo,
Well let's get this straight, if you activate the "custom" needs to disable "Show" not to be active in recording the two modules, when you enter the part of customization changes and exit, when he is back in "Demonstration" because the standard method of entry but if your looking for customization that you changed it continues on, not being changed.
This is my thought to what can entedender of your doubts.

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:

Importing EDL project frame rate is always 23.98

Hi There,
I'm importing a 24 frame EDL. All of the import settings are set to 24 fps. However on import, the project frame rate is always 23.98.
I have added the number 24 to the defaulteframerate section of the preferences file, but no luck.
Anyone found a solution to this?
Thanks

Just a wild guess since I don't normally work in 24 fps... all of us NTSC-biased types accept that 23.98 (more accurately, if not absolutely precisely expressed as 23.976) is the "pull-down" frame rate that results from a telecine transfer, and is the rate that is assumed, corresponding to 29.97 or 1000/1001.
This framerate is emulated in a number of "Digital Cinema" electronic origin formats.
Absolute 24.0000 fps is a bit rare in these parts and in reality probably would only come up if one were working with a dpx image sequence properly scanned, not telecined.
Not saying that 24.000 does not exist -- I'd say that it is just as uncomfortable a fit in 25 fps-land as it is here! And Color / Final Touch has been notoriously bad with 25 fps.
good luck and merry christmas....

How can I edit multiple clips with different frame rates on the same timeline

how can I edit multiple clips with different frame rates on the same timeline

You do not want to edit material from different frame rates on one timeline. You CAN do this, but it is a very bad idea - and this is why.
Once you establish the sequence frame rate - lets say it is PAL material at 25fps, any material that you drop into the sequence other than 25 fps will have to be changed to play at 25 fps. If the material you add is NTSC (29.97), FCP will DROP 5 frames per sec to bring the frame rate down to 25 fps. Which 5 get thrown away? Every 6th one. This yields a funky cadence that becomes even more complex as as there are also interlaced fields (DV/NTSC is an interlaced format). Oh, and by the way, the image sizes are different as well. DV/PAL has 576 lines of resolution and DV/NTSC has 480. FCP has to scale up the NTSC to fit the PAL frame.
You do not want FCP adjusting these things on the fly. You want to do a thoughtful (and time consuming) conversion so that you end up with all your material in one format with the best possible image from the conversion process. Compressor can do an adequate job with Frame Controls turned on. The Natress Standards Conversion FCP plugin is another way to go. A third option is to find a post house that can do the conversion for you using a hardware based process.
The good news is, once everything is in the same format, editing it will be painless and the output process very quick.
Whatever frame rate/ image size you select, I'd suggest using ProRes for the codec. It is 4:2:2 color and will withstand color correction and composting with much more grace than any variant of DV based codecs.
Have fun.

How can I change the frame rate mode?

Adobe Premiere Pro exports my videos with a variable frame rate. Because of this long videos are asynchronous. How can i change the frame rate mode? So Adobe Premie Pro exports my videos with a CONSTANT frame rate? The original video has a constant frame rate...

Sorry my mistakes. I am from Germany.. so...I mean with asynchronous that the video file and the sound file are displaced. In the beginning of the Video it's normal, but if the videos is very long it goes VERY "asynchronous"
I analyzed the video with "mediainfo":

One swf running on lower frame rate

Hi,
I have a basic loader swf, which loads several external swf's and displays them in a browser. Now all the other swfs work just fine, at 24 fps, but one particular swf drops down to 12 or 11 fps in the middle of the timeline. Why is this happening?? And how can I get it to run at the same frame rate as the others.
There is some heavy animation in all the external swf's but that does not seem to affect any other files, only this one. Also, the animation is not heavy throughout, though the low frame rate persists...
What could be wrong???Any help will be greatly appreciated..as the entire site is looking bad because of this file...:|

Have you tried just loading the problematic file? Does is play better? Does this problematic file play correctly alone?

Best frame rates for 4 different cameras in multicam

Well, I've been flopping around in different threads on this forum, but I think the question is beginning to finally take shape for me. Basically it's all about deciding on frame rates for four different cameras I will be using to shoot a 6-day intensive course I will be teaching. The video will be primarily for computer viewing (YouTube, Quicktime movies). Here are the cameras:
2 new Canon cameras capable of frame rates of 60i, 30 frames per second progressive "recorded as 60i", and 24 frames per second progressive also "recorded as 60i" (there is a known issue with importing the 30 frames per second into fcpx, as fcpx does not recognize this as progressive, but ClipWrap can get around this).
1 Sony capable of 60i, 60P, and 24P
1 Sanyo capable of 60i and 30P
Possible settings:
Just do all at 60i, but people say this is not so good for computer viewing
Canon at 30 fps (using ClipWrap to see it gets recognized as progressive), and the Sony and Sanyo at 60i. Will this cause syncing or other problems, mixing frame rates like this? How bad a hit in quality is 60i on computer screens?
Canon and Sanyo at 30 fps, Sony at 60i
Same as #3, but use JES Deinterlacer to get Sony 60i to 30 fps.(I tried this out, by the way, and the resulting frame rate, after deinterlacing, showed up in the inspector window at 30, not 29.97. Is that a problem?
Anyway, I aplogogize for wearing out my welcome on this forum, and I thank everyone for creating such a wonderful bank of information.

Not sure what you're trying to achieve here - for the best overall quality, if possible, choose a frame rate that all the cameras can achieve. That way you won't lose quality in the conversion.
If you're not satisfied with that, you need to do some tests to see which gives you the effect you like best. Nobody here can help you really - it's up to you.

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)

Reconnecting media after frame rate change

Shane Ross wrote a reply ( see below ) to a person that had the same problem as I am now.
I shot with HVX200 using the Firestore that converted footage to 59.94. Then, mid-project I shot with the P2 which shot at 24. I now have 2 diff. frame rates
I tested some clips in Compressor comverting the 24 to 59.94.
Using FCP Studio 2 , I was unable to reconnect the media without the in/out points being off with varying degrees. Doing an entire re-edit will be painful.
QUESTION : Do I really have to convert the 24 to 59.94? Would it significantly affect output?
The codec is the same for all footage. ( DVC PRO HD 720P. )
THANKS!
[elizabeth charles] "My question is, is there anyway to change the files in my timeline to the conformed files without having to begin my editing again?"
Nope.
You did a bad thing. Editing, finishing, then changing the frame rate of your masters. FCP cannot reconnect to media with differing frame rates. Because the duration of the footage is different, and the frame rate is different. The footage has the same amount of frames..., but now they play at a different frame rate, so the duration is different. You'll have to re-edit with the new masters.
But...RECONFORM...that changes the frame rate, as well as the speed in which they play. 30fps conformed to 24fps will play in slight slow motion. If you want the footage to play at a different frame rate, but the same speed...normal speed...you need to use Compressor.
Shane

gang allows you to lock the viewer and canvas together so when you move one, the other moves the same amount. To match back your footage, you find a frame with a clear difference from the previous frame, for example when someone blinks. You then find the blink on the new source file in the viewer and then turn on the gang function It's the center thingamagic at the top of the canvas. You then jump around the shot in the canvas and make sure the movement in the viewer matches. you then find the in in the canvas and mark an in in the viewer, etc and replace the shot. If this isn't clear post back.
In compressor in the frame controls panel, you enable frame controls and set the rate conversion to best.

Subtle Frame Rate Variation Effects

I am working on a project to create a silent film look. In particular I am after capturing issues associated with the frame rate variability associated with both cameras and projection at that time.
Some thoughts based on my reading...
Seems like two issues are at play. One is that the capture may have been at around 16 to 23 frames. It seems that unless people were going for comic effect they were not intentionally sped up by showing at a faster projection rate. In looking at some old classics by and large people seemed to try to match capture and projection.
However there is a “crispness” associated with the quality of the movement. My guess, I am totally new to this, is this results from 16 to 29 fps capture - less frames in a second to provide the perception of smooth movement.
My thinking is that I should see if I can convert my base footage to a sub 20 fps frame rate that covers the “crisp” movement aspect.
In looking at old films it seems like there is another dynamic at play. There seems to be the equivelent of wow and flutter in analog play back devices (phonographs, cassettes) in relation to the timing - it changes in a subtle way over time. Perhaps there is a way to introduce subtle timing “white noise” to simulate this effect.
I am just coming back to FCP and Motion after a several year layoff, so I am not completely familiar with ther current capabilities.
So with that my questions:
1) I dreamed up the above with respect to approach. Any merit to this? Other ideas?
2) Are their tools in fcp studio to do a quality frame conversion to sub 20 fps?
3) shooting. Initially I thought that I would want to shoot at 24p in order to get closer to sub 20 fps. Maybe it makes sense to shoot at 30p or 60p (my other two choices) to create more frames to get to a higher sub 20 result. Thoughts?
3) Thoughts / approach to getting wow and flutter to simulate variable projection and or crank camera capture?
Thanks in advance for any help.

As Mark said, the Bad Film filter does a lot of weave and frame jutter automatically.
Another thing to try in addition to Bad Film are the retiming behaviors in Motion, particularly the Stutter and Flash Frame behaviors, which can introduce the kind of timing errors you are talking about into playback of your video. You can also apply a Randomize parameter behavior to the Retime Value parameter to get more interesting random playback effects.

Can I throttle frame rate on server side?

I am building many to many webcam based chat application . The application page on client side will show streams anywhere from 1 up to 10 webcams. Most of the streams or chat will inactive so I am thinking that I can broadcast those inactive streams at a very very low frame rate untill they get activated. { I know I can not throttle in flash but can I throttle on server side with FMS or Wowza server?}
Any hints regarding how would I achieve this?

What do you mean by inactive streams - if you mean there is no data to be transfered why do you want them to broadcast at first place? Probably i did not get your question properly if that's the case can you elaborate more?

Variable Frame Rate on H.264 output

I am using AE CS6 (cloud version). I am trying to render compositions to 1080p mp4. Each time the comp appears to render fine. But bringing it into my NLE crashes my NLE. I brought the media into MediaInfo (app from SourceForge that shows everything about a media clip). It says that the Frame Rate is VARIABLE Min: 60fps; Max 60.6 fps. The composition was 80 fps, and I told the renderer to keep it at 80. MediaInfo also said the duration was over 6 seconds. The composition was a little over 4 seconds. So the overall speed of the comp was incorrect. I've been in the video business for about 10 years. I understand frame rates, etc. Never heard of VARIABLE frame rates until this.
I was able to launder the media file through a freeware media format converter, and got it back into constant frame rate so I could proceed in the NLE with the project. But the time was still 6 seconds. So I had to speed up the clip in the NLE to get it back correct.
Since moving to CS6 from CS4, I decided to start using the H.264 output module. So I've just started encountering this variable frame rate problem.
So my questions... What is variable frame rate, how did I 'request' it, why is even the variable frame rate no where near the comp frame rate, and what do I do to simply get an mp4 with the 80fps that I want?
This is very reproducible for me. My comps are usually either HDTV 1920x1080 or HDV 1440x1080.
Add to Render Queue
Select DV Settings, change field order to none
Select H.264 output module
Render
Can someone explain what's going on?
Thanks.
Jerry

Where did you get that footage and what format was it originally shot in? Was it shot in slow motion or did you change the frame rate in AE? Why would you need 80fps footage unless you're going to slow it down to a normal frame rate?
Also, h.264 is not only a very lossy format, it's also a bad intermediate format. So if you're planning on editting that footage later on in an NLE, I'd suggest rendering it to something else. Premiere should work fine with h.264, but not FCP, although I think they fixed it in FCPX, but you didn't say what NLE you're using.
Second of all, the H.264 encoder is much better in Adobe Media Encoder. Check this post by Andrew Yoole:

As the other guys have said, don't use AE to render using temporal codecs. Temporal codecs like H264 rely on storing partial frames based on earlier information. AE renders and encodes one frame at a time, so most of the efficiency of a codec like H264 is lost. The result is that you get much lower overall quality from an AE h.264 render than if you were to encode it externally.
Adobe Media Encoder or Quicktime 7 will encode great quality H.264 files.

As I said I'm not sure why you would need to take an 80fps piece of footage back into an NLE, but if you're trying to make that footage play back in slow motion, you're going to have to re-interpret the frame rate of the footage in After Effects to play back at standard rate. And, if you're going to use the AE Render Queue to output something for more editing, I would suggest using best settings and outputting to a production codec such as a ProRes, Animation, Uncompressed 10bit, Uncompressed 8bit or Black Magic.
Also I've never used that media info app before, but I know that when you open up quicktime and hit command I on the mac to view the inspector, the playing fps jumps around. I think this happens because the player doesn't necessarily play back the correct frame rate at all times.
This Adobe Captivate blog talks about variable frame rates in F4V files. Maybe it might help explain things.
