Frame rate drops on 1410 and 1405 cards.

Hi-
I am using a 1410 and a 1405 card.
I am experiencing a problem of dropped frame rates while using imaqGrab function. I am putting this in a timer control ( just like hlGrab example provided with nivison) and get really high frame rates and then a drop to really low frame rates. The drop seems to be at consistant intervals. I have tried using each card independantly to isolate problem. Happens with each card independatly. I have tried using a buffer and not using a buffer. Timer control on UIR is set to 0.000 for timer interval so should be happening as fast as possible. Anyone have any ideas?

Hi Blue,
How do you see the frame rate drop and how do you
measure
it? What is the expected frame rate in your application?
Thanks and have a
great day.

Motion 5 Frame Rate Dropping

So I'm using motion 5.0.7 on my 2010 MacBook Pro with 8GB of RAM and no other applications open and when I play video footage at 1080p at 25fps in the playback window, even if I have done nothing in the way of editing it, the frame rate drops to 7fps and lower. This is particularly frustrating as the video tends to 'jutter' when playing back?
Any solutions?

Well, laptops don't have the most powerful GPUs in them, which is an issue for Motion. What is the duration of this project?
Go to the Render menu (top right in Canvas) and make sure you turn off all functions you don't need (lights, shadows, etc) and drop the quality and resolution settings a bit lower.

World of warcraft/Diablo 3 frame rate drop to about 25% of normal frame rate and I have to reset SMC to get it back to original. But this happens once every 2-5 days. Is this normal!?

I purchased a 15 inc retina mac book pro in Sep 2012 and everything has been perfect except when I started to play world of warcraft and Diablo 3. After I first installed the games, their frame rates were so bad and the games were un-playable (<10fps). So I spent quite a bit of time searching on the internet and eventually found a solution which is to reset the SMC of the machine. I did this and everything was fantastic, frame rates go up to 30-60 fps on the same settings. However I then realise that I have to reset SMC every few days as the framerate become bad again and again. The frame rate doesn't drop gradually. It is sudden - yesterday the games were fine, today when I turn on the computer they become unplayable.
Any help is appreciated - I tried to contact apple by going through the solution process they have on the website but it just asks me to take the computer to the apple store but I don't have time to do so. It will be great if there is a phone number I can call.
Cheers

Hello Sinaxwe,
This is not a fix but a work around.

Log and transfer not changing frame rate to slow motion on P2 cards...

Hello.
I swear I have done this before on final cut studio 2 and it came out correctly, but for some reason this time, either myself or the computer is making an error. (chances are it's me).
Basically, I'm logging and transferring footage that was shot on P2 at 50 fps, and my intention is to import it at 23.98 fps. I thought this is something that naturally happens in the log and transfer process, but i guess not?
My project was set up via easy set up at panasonic dvcproHD frame rate 23.98... and I'm logging an d transferring directly into my browser but the f frame rate stays at 50 fps. (footage was shot in England to be incorporated into a video already shot in America).

I thought this is something that naturally happens in the log and transfer process, but i guess not?
Your guess is right...it DOES NOT slow it down upon injest. ONLY if you set the camera up to shoot 720p25 and then choose the 50 frame rate (I hear this is what you do...I am not a camera guy, so...), then it will import slowed down. But you have to set the camera up CORRECTLY. The first time I imported slow mo, it was 60p...and I had to use the Frame Rate Converter to slow the clips. Then my camera guy figured out the setting in camera and BOOM...there it was.
So...I guess you are NOT wrong...actually. It just needs to be set up IN CAMERA in order to do what you want.
and I don't know if the Frame Rate Converter works for PAL footage...stupid, but...no...Stupid.

Export Quicktime = stalling / frame rate / dropped frames

Firstly this issue isn't news. It appears it has existed since 2002 at least on these forums and Apple has done nothing.
Exporting to Quicktime:
1) Keynote makes up what seem to be consistent random frame rates on export
- Codec doesn't matter. Photo JPG, Intermediate, 8bit 422, H264
- You can set the frame rate in export / custom / settings it doesn't matter
- Having no video on a slide or having video on a slide doesn't change the problem...
- The last two items do have more information to complete their story
- If you do have a video on slide at say 25fps and export (at same rate) the random will stabilise
but it will stabilise to something bizarre, such as 23.69.
- So Keynote can wreck your frame rate it will drop frames, or even add frames while dropping
others. It is deeply sophisticated in how it destroys stuff on export.
Result
- is a stuttering output if embed video on a slide with a wrecked frame rate
- and a random frame rate if you don't have a video embed
2) The video stalls between slides
- Keynote seems to play a trick by making a single frame span multiple frames
- At the start of the first slide this seems to vary. The first frame can be between 7 and 33
frames depending on some strange internal logic only known to Keynote
- Between slides it will hold the last frame of the exiting slide usually for 7 frames and hold
the first frame of the entering slide for usually the same amount.
- No amount of change to settings such as transition delay, adding a transition, self play etc
will effect this stalling from what I can tell.
- You can analyse the reality of the issue by dropping the resulting file into Quicktime 7 and
changing the video window "time code" display to frames by clicking on it and single framing
through the video. I have Quicktime Pro for the record.
Notes:
- I have every update installed and am running 10.6.2
- I have tried it on two machines, one a clean build, server or client
- Playing the presentation direct in Keynote does not present any of the noted issues
- I have spent the better part of two weeks on the issue trying all sorts of combinations
- Video of different frames rates, sizes, codecs. All useless, don't bother.
Outcome:
- Keynote is completely useless unless you just want to play a presentation in it
- Dropped frames, stuttering video, stalling, mangled frame rates, fake frames
Solutions that aren't:
- One suggestion for video embeds is to enter a strange custom frame rate. For example a
24fps original turns into a 23.69 export, if you up the frame rate to 24.3 the resulting export
is 24fps.
This is a truly hit and miss affair and will require a lot of testing to nail it. Unfortunately I
tested the resulting video frame count in Quicktime against the original video and...
The amount of frames is not the same. Part of my assumption is that the stalled pad frames
are being considered by Keynote and it drops some frames to fake the same length, that at
least -seems- to be part of the result, but it doesn't account for all the lost frames.
- I have also tried just having one slide and exporting that. The same things happen regardless
How Al Gore managed to make "inconvenient truth" using Keynote is a complete mystery. Maybe on Tiger with some old version it used to work, yet from the forums it would appear it has never worked. This piece of software is a clear case of "it just doesn't work"
I hope you find this and stop hurting yourself trying to make this. I might hurt on a bit longer yet.

I can't answer in detail (I started with version 6, which I haven't used in years, so don't know what v5 did) but... a general comment
Software that old is very likely going to struggle trying to edit a VOB/MPG file copies from a DVD
If you are digitizing by playing the DVD through a conversion device you should end up with DV AVI which should edit well
Just what kind of files are you trying to edit?

Frame Rate Drop

Hey, I am finishing a course in graphic design, as of the last month and a half I have had incessant problems with the frame rate of Flash Dropping. I am using the same computer as I have throughout the course, I keep it clean as it is a work only computer, and I haven't done any changes to it.
For reasons unknown my frame rate has been hitting the floor in everything I do. First I tracked the problem to overloaded my CPU every time I use flash (this has never happened before untill now). I thought it just might be a case of poorly put together projects as many discussions on here suggest, or perhaps the websites I visit overload their pages with flash media that simply is too much.
However I was looking at my old projects a few days back, really simple things, that used to play great; now I have the same issue, very choppy.
The biggest problem however i noticed is when after looking at my old projects I began to make a new one, and as I barely started the projects (20 minutes in). I noticed when I use the playback, the frame rate steadily drops from 20fps to about 4 - 3.4fps.
The choppyness I have witness before on 2 other computers I use mainly for leisure, but I thought it might have been something I did wrong when I reformatted them recently, untill this computer started acting up.
Now the issue have spread, and many of my own friends report the same problem when trying to watch anything flash related. Clearly it's not just me, as many of the discussions would suggest.
Anyone have any ideas what it could be? My guess, its something with the new Adobe Flash Player, not to say that it's bad, but perhaps something it utilizes requires different settings than the old one?
Help on this matter would be extremely appreciated it. Thank you.

Long shot guess, but Im thinking it has to do with the difference between fields and frames. The upper right arrow points to 59.94I . "I" stands for interlace. There are 2 fields per frame in interlaced video. The lower left arrow points to 29.97 fps. That stands for frames per second. The frame rate is half the field rate hence the differing numbers. I dont think anything has changed. Just the yardstick measuring the data.

Frame Rate drops to 1FPS after 30 seconds

Recently my iChat has begun to behave strangely. I can initiate and respond to iChat video chats and my frame rate starts off a healthy 15 fps and the bit rate is about what I'd expect (300+) but then both fall off sharply over the first 30 seconds and bottom out at 1fps and around 60 kbits. I can see my buddy at 15fps and sound and video are green at 100%.
I don't know if it's related but Spotlight has stopped working too and I can't fix that.
I've trawled the web and tried many things but can't find the answer. I hope somebody can help.
15" PowerBook G4 Mac OS X (10.4.9) iSight Camera

Hi Paul the Artist,
One thing first.
iSight does not like to be daisychained. This can even be a problem if it is ganged ports on the computer going to the same Firewire Controller.
The Spotlight problem may be Indexing linked as you say.
Open the Activity Monitor in Applications/Utilities
Make sure the Drop Down at the top reads All Processes
Now the lower section (no icons) should be system stuff below the icon for the DOCK.
Above that are the newer Apps and newer things running (some without icons owned by Root and some by "you"
I can not remember the exact name but it will be one owned by you but with no icon and called something like mdimport
You will need to see if it implies or states it is Not responding OR shows lots of CPU usage.
If the indexing is finished it should say it has no CPU usage.
Force Quit it if required via the big red Quit icon to left.

Frame rate issue with AVCHD and CS4

I've been using a Canon HG20 recently and the whole experience of AVCHD has been a nightmare. I finally have a computer that can handle playing the native files in the Premiere timeline but it looks like there's a problem with the frame rate. It was shot at 1920 x 1080 and the frame rate was set at 60i.
When starting a new project I used the AVCHD 60i preset and the clips don't need rendering which tells me the settings should be correct. But something is definitely very off. I thought there was a slight chance it was a performance problem so I tried burning footage to a DVD and it looks exactly the same. Here's a clip I uploaded that shows the problem:http://www.vimeo.com/6443990
Does this look familiar to anyone? Any ideas on what the disconnect between the camera's settings and Premiere's settings might be?

It looks like it might be skipping frames or something. The movement looks wrong.
Just realized something. Please forgive my ignorance, it's only my second day using CS4. The clips I place into the timeline have a yellow bar above them. So I'm guessing this means that the frame rate of the clip doesn't match the project settings. I've tried all of the AVCHD presets. I can't place a clip in any of them without the yellow bar. When I right click on a clip and select 'properties' it shows the frame rate is 29.97. So what's with the yellow bar if the project settings match that?
Is there a way to tell if the HG20 shoots in 24p over 60i? And if that's the case how does that affect my project presets?
I have to be making some kind of simple newbie mistake here.

GTX 970 GPU usage spikes and Frame Rate drops

Hi all, anyone having the same issue?
I'm playing a relatively low(?) graphic intensive game ( League of Legends ) and this also happens in the sims 4. I have The Crew and this issue does not happen so frequently. Could anyone kindly assist to provide me some info on this?
My driver version is the latest (347.25)
My system specs are:
Windows 8.1 Pro 64bit
ASUS P8Z77-V Intel i7-3770 @ 3.40 GHz
CORSAIR VENGEANCE 12 gig ram ( 3*4g )
MSI GTX 970 4G Gaming
Corsair Force GT SCSI 120 gig (SSD for OS)
Western Digital WD1002FAEX 1tb (HDD for Games,Videos etc..)
SeaSonic M12II Bronze 620W
If anyone needs any more information please let me know... Sorry for my English as it is not my native tongue...

CORSAIR VENGEANCE 12 gig ram ( 3*4g ) <-- that will cause a performance hit as you will be in single channel on the memory not dual channel! (on that platform you need even numbers of sticks and a odd amount will force single channel only (for max performance its 2 or 4 slots populated))
it could possibly be contributing to you issue!
Badboy2k first of all thanks for the very quick response! Secondly, does it mean that I would have to pluck out 1 of them? And is there any order or position I have to place them in? I had 4 sticks but 1 of it was spoilt so I took it out...

Severe frame rate drop when touching screen iOS

Hi there,
I have a simple app with 2000 clips scrolling up the stage with a bitmap in each. They are moving around blazingly fast at 60 fps.
But the moment I even put a finger on the screen the fps drops to around 40 if i move my finger it drops down to 30 fps.
is this normal behavior ?
there are no event listeners or anything like that.
thanks :-)

I have a UI that is the first thing present in my app. It has a grid of buttons. I contain all the buttons (movieclips) inside of 1 main movieclip (interfact_mc) and I'm not seeing a framerate drop when interacting with them. GPU rendering with a constant 60fps.
I am sorry but this doesn't allow to conclude to anything because :
If your app is showing 60 fps, it could (just picking numbers for the example) mean a theoric 200 fps and a drop to 65 fps when you move your finger on the screen (tapping has less impact) = 10 ms each frame which is the same as a drop from 59fps to 40fps. It just mean your app is not eating much (and that is a good thing but not helping).
I also suppose devices, publish mode etc, impacts.
I made some tests here trying to be as precise as possible : http://forums.adobe.com/message/4880341
If you found out any reason/possibility to avoid this, I would be very interested. I could try to unest evertyhing but since everything is already tested with mouseEnabled/children false... I find it quite wrong.

MSI N660 TF 2GD5/OC black screen then frame rate drop

Had Radeon card, moved to this gtx 660, but now I get black screens randomly after a few minutes, at which point my framerate drops to unplayable. If I restart the game it is fine. Having problems with Borderlands 2, Crysis 2 and Dishonored. l4d2 and Walking dead seemed okay though.
Uninstalled AMD drivers, and ran driver sweep. I have the newest drivers from the nvidia website. My power supply is more than powerful enough. Doesn't seem to be any overheating. Searched online, but not finding any solutions.
Very frustrating, never run into graphics card problems like this before.
Any help would certainly be appreciated!

Try monitoring temps while playing with Afterburner OSD and report max temps: >>How to use MSI Afterburner<<
Max temp was 60 playing Crysis 2.
There were no spikes in any of the graphs.
Quote from: xmad on 28-November-12, 05:35:01
Two other things:
1.) Are you able to test the card in another computer?
2.) If it works fine there, try updating the mainboard's bios.
No, I can't easily test it in another computer.

Why the frame rate drops (stuttering) in every 10 seconds?

I am using AS3 to design the application, I set the FPS to 25, in every 10 seconds, the FPS drops(stuttering), and the screen hangs for about 0.5 seconds, then FPS resumes. I tried GPU, but still the same. I suspected that it might be very resource consuming, and I lowered down the FPS to 16 or even 8, but it still stutters in every 10 seconds. Can some one help me?

you need to optimize your code/display especially if you're creating an app for a mobile device.
one of the easiest things to do is to enable the cacheAsBitmap property of most movieclips and assign a cacheAsBitmapMatrix to those movieclips that would benefit.

Large Frame rate drops

This problem mostly occurs in CounterStrike:Global Offensive, in any game server this will happen. However it happens in other games like TF2, and Minecraft. I am going to factory reset my computer and upgrade to windows 10 tonight/tomarrow, to hopefully fix it.

My laptop has always been very efficient and useful, but a couple problems have been occuring with it latly. One of the largest problems, is my Increadibly huge framerate drops happening this past month. Windows 8.1 without many tasks open, will run fine. However, I will open up a game (All games do this) and then about 15 minutes later, my notebook itself gets a framerate of about 1 or lower. A minute or two later, it returns to normal. Then the cycle repeats. I am sure it is not my internet, because it makes my whole computer lag. Also, I have a couple of occuring problems lately that may relate to this.My computer fan makes a buzzing noise, and sometimes I will start Windows and it tells me tht my system is not being cooled properly.My touchscreen does not work after starting windows, but at any given time it will start working again. How can I fix my main problem?

Frame rate drops since 11.7.224

Hi flashplayer team,
We were very suprised when we found out our app works fine on versions prior to 11.7.700.224 and then after update the fps drop when loading a module (and is just one of many modules).. after the module is unload the app works fine again... is there any specs that We have to be aware besides audio/video (http://blogs.adobe.com/flashplayer/2013/05/extended-support-release-updated-to-flash-playe r-11-7.html)?
We realy need help here, otherwise we will have to advise our customers to downgrade their version of flashplayer.. witch is "impossible/nonsense".
We've installed all versions above 11.7.700.224 and all reproduce the same result.
You can test here: https://editor.dreambooksworld.com?lang=en_US
how to reproduce?
1 - pick "Photo Printing" category and start any project.. you'll notice right away a drop of fps in all Application.
On all other categories this issue is not reproduced, and all other categories are modules too, loaded the same way and builded the same way.
The app uses Swiz framework.
Kind regards

We're running into similar issues. We find we get the best
results downsizing a 720x480 capture from our camera to a smaller
window from a quality perspective. We're using a dual processor
2.4GHZ server with 4GB of ram and can only sustain about 22-23 fps.
How is everyone streaming larger display sizes than 320x240
while maintaining top quality video?

Frame rate drop while streaming with FMLE 3.2

Hello,
I was streaming locally at about 300 kbps, about 10 seconds after I start streaming, it pop a brief message that said : "buffering" and
the framerate drops to 90 kbps and there is about 4 seconds lag between my monitor and the stream result. (there was less then 1 second before)
Any idea how can I fix this buffering issue?

receiveVideoFPS is method of NetStream class. For more information about this, you can check the following link:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/NetStream.htm l#receiveVideoFPS()
This can be set in the player code.
