Sync'ing movieclip frame rate with movement on screen

I have a situation where I need to move a wheel on screen (based on user input on speed and acceleration) in such a way that the wheel rotation is in line with movement on screen, so wheel doesnt appear to slip. i.e in a given internal, wheel speed=wheel rotation * 2*pi*r
As the wheel moves with user provided veleocity and acceleration across the screen, how do i control wheel rotation- I have built the rotation in Flash Pro in 40 frames- is there a way to dynamically control the movieclip running to achieve this?

Stage.frameRate?

Different frame rate in movie mode? iPhone 4

I noticed that my iPhone shoots video clips with different frame rate from time to time. I suppose it slows frame rate on dark shots. For now all of my daylight shots are 30 fps, while night or dark ones are 25 and 24. This makes it hard to edit clips in iMovie for example, because difference in frame rate causes strobe motion effect on output.

Anybody have the same?
For reliable results I would suggest to shoot two clips: one in sunny daylight conditions, another with ordinary room lightning, maybe a little darker than normal.
Please let me know of the results. Thanks

Doesn't seem to be just a Quicktime bug:

Low Frame rate with new Apple TV.

Hi,
I just watched a purchased TV show (Top Gear) on my new Apple TV, connected to a 42" flatscreen, and I am not impressed at all with the quality. Apart from the resolution, which we all now, the image is jittery, and the frame rate is so low that when somebody moves his arm you can wee it jump from one frame to another.
Looked at settings on my TV (Sony Bravia) to see if there is something there, but I don't see any setting that might affect this.
Anyone else has this experience?
Kind Regards,
Erwin

Same issue with a British movie I just tried to stream and I didn't think this would help, but it worked like a charm! Definitely the cinemotion. I didn't even know I had that setting. It's way to the left under picture in my Bravia onscreen menu. Just make sure that you turn it off for the correct input. Im more used to using the motion enhancer toggle under options, but that wasn't it.

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?
Thanks
Richard
ps I use 2014.2 latest version

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

What is frame rate with 1920x1080/60p?

I'm currently shooting and editing HD 1920x1080/60i (interlaced format, 29.97 frames/sec). To reduce motion artifacts, I'm considering a change in my workflow to HD 1920x1080/60p (progressive format), but first I must update my understanding of this newer format. Question 1: What is the frame rate for this format, 30 or 60 frames/sec? If the answer is 30 frames/sec, why is it called 60p? Question 2: How many complete scans (combining odd and even lines) are produced per frame? Question 3: Would a Master File exported from Final Cut Pro X (by default, a QuickTime movie file) be progressive or interlaced? Question 4: Would iDVD v.08 accept a progressive movie file for making standard DVDs?
Your answers to these questions are very much appreciated.

Thank you, Tom Wolsky and Karsten Schlüter, for your fast replies!
Tom, regarding my Question 4: Are you sure that the latest version of iDVD can accept progressive 1920x1080 QuickTime movie files at 59.94 frames/sec? As you may know, iDVD is no longer supported by Apple, and their Technical Support is unable to answer my question. I respect your experience in this area and would like you to advise me in my proposed switch to a progressive workflow. I can't afford to shoot in a format that will not allow me to make standard DVDs.
Best regards from Interlacer.

Slow frame rate with Prosilica SmartCam

Have here a Prosilica AVT GT1600C and a very slow frame rate...
Here are my .icd information.
I tried to cope with the balance between the ExposureTimeAbs and AcquisitionFrameRateAbs but dont help.
The .icd file is attached (renamed to .txt), installed version: Vision 2013f2
Does some of the vision cracks find some optimizing issues?
thx in advance

Ah well, yes... the variables/options are:
lighting - this is the most commonly overlooked, and often the easiest to fix; use/buy more/better lighting!
lensing - be sure you select a good quality lens (a good lens is more expensive but passes light better), and that the aperture is open as far as possible (unless you have depth of field issues)
exposure duration - as long as possible relative to framerate desired or to prevent blurring if motion involved
use of gain - this should be a last resort as "noise" increases with gain... but slight use of gain can be helpful under marginal lighting conditions

Low frame rate with mac to pc video chat

I have a mac with isight using Ichat and 10.4.3. My brother has XP with AIM 5.9 with the latest and greatest Logitech USB 2.0 webcam.
We are able to connect and start a video chat. We see each other. The frame rates from the isight are great on both ends. However, the frame rates from the logitech are about 1 fps on both his computer and mine. We have tried adjusting settings and installing the AIM patch that was referred to in one of the articles.
what to try next.
thanks in advance

NVidia GT 120 and intermittent low frame-rate with Expose, Dashboard...

I have an iMac early 2009 with a NVIDIA GeForce GT 120 (256 Mo) graphic card.
I have intermittent low frame-rate problems with Expose, Dasboard and several other large animations...
For example, when I trigger Expose or Dashboard, the animation may sometimes be choppy (with few intermediate images) to very choppy (practically no intermediate images)...
The second after, the same animation may feature a very high frame-rate...
Neither Apple diagnostic tool nor TechTool Deluxe finds any hardware problem.

I have the same iMac, and also have this same problem.
When I first activate Dashboard, the animation is choppy. If I activate it several times in a row very quickly, the animation smooths out noticeably. It's as though the video card is asleep, or cycled down, and then wakes up and springs into action.
This is testable. If I run the command line utility OpenCL Bench immediately following a restart, my iMac's GT 120 gives a time of 14 seconds. If I open iTunes, turn on the visualizer, and then run OpenCL Bench again, the GT 120 gives a time of 1.7 seconds! If I turn off the visualizer, wait a few seconds, and re-run OpenCL Bench, the GT 120's time increases to 5.6 seconds.
The same performance increase/decrease shows up with Dashboard. If I open Dashboard with the iTunes Visualizer running, right off the bat, Dashboard's animation is very smooth. If I turn off the visualizer and wait about 30 seconds, Dashboard's animation is back to choppy.
This is not dependent on the iTunes Visualizer. I can have the "OpenCL Procedural Grass and Terrain Example" running, for example, and get the same results from OpenCL Bench and Dashboard.

Can you adjust the frame rate with quicktime?

I need to slow the frame rate on an .avi file, and I can find how to do that in big chunks, but how to fine tune. Is this possible on the latest release (just downloaded it) and if not can someone tell me what I can use to change the framer ate on the .avi itself (either way is fine)
I am SO not tech savvy so please assume you are replying to an idiot but thank you very much in advance for any help.

p.s. I discovered that holding the option button and the fast forward give me this control for speeding things up, but I can't figure out how to slow it down - sorry for the missing info

Sync'ing ezdrummer, Superior Drums with Logic pro

Hi - I am trying to sync ezdrummer and superior drums with the measures and metronome on Logic and can't seem to do it - the metronome is completely of and each measure in teh drum pattern ends up in the middle of the time bar on logic - completely random. This is in spite of resetting the temo on the project (which shouldn't be necessary)
Any help would be appreciated

Hi Erik,
I 'play' in my drums by 'drumming' on my keys - is that also called 'programming'?
My definition of 'drum programming' is:
It is acceptable to say you are programming if you're editing MIDI events or regions in the process, recording/editing within a composition of multiple MIDI performances, if entered with a controller or manually, modifying the sounds or samples used by a performance, and many other scenarios. 'Drum programming' encompasses most things which are aided by a sequencer or a sound generator (I'm not considering live drums in this explanation). 'Programming' is such a vague term, there is nearly always a better word to use (assuming you want to be specific), because the term can be used for just about anything related to MIDI events or sound generation/reproduction/sound design for a drum track or loop.

Low frame rate with mask

I added a mask to a mpeg1 .mov file to remove the letterboxing, and now it plays at like 6-7 fps. I had no trouble with the original file, and my computer should obviously have no problems keeping up (the file is only 320x176). Any ideas on what the problem is or if this is common?

That is not an inherent problem with masking mpeg1 files. I just did it in QT 6 to a similar sized 29.97 FPS mpeg and it didn't slow down the FPS playing rate. Perhaps you should try it with a different mpeg and see if the problem is unique to that first one. If it is a general problem with mpeg then try it with a .mov file. If the slow down remains when masking then it probaably should be reported to the QT team at the feedback page:

Sync'ing ITUNES Contacts list with MS Entourage

On my IMAC I have 2 contact/address books. I have 1 I migrate into Entourage with phone contacts and important EMAIL address and then for the IMAC address book that contains just EMAIL addresses. I can't find an option in ITUNES to sync my Contacts in Entourage which is the contact/address book I what on my IPHONE.

I did some "digging" and answered my own question. I first merged my Entourage Contact/Address book into Address book. Then in address book I created 2 groups, IPHONE and IMAIL. I then went in went into the address book area showing all of the addresses and contacts and just "drug" which addresses I wanted into which group. Some I "drug" into to both groups. I then went into ITUNES and under Contacts in the INFO tab I checked "Sync address book contacts" and checked Selected groups and then check my "IPHONE" group.
Round about way but it works.
