Playback drops frame rate when context menu opens

Hello,
I was wondering why is frame rate of the video drops when I open the context menu, the playback seems to go down as much as 5fps, and it goes back to normal when the context menu is closed.
Thanks in advance.

lghtanddrk, if you send me a link to your AVCHD MTS file, I can trying exporting it as a MOV file and see if I get the same issue. For me QT seems to be slowing no matter what HD file I give it.
What camera did you use to shoot your footage and how big is the AVCHD file? What's the data rate of your MP4/H.264 file? Again, if it's possible to get some of your MP4 footage, I can check if I have problems playing it.
I have two partions on my machine: one is WinXP SP2 without the updates and QT7.3.1 (for Avid XPress Pro) and the other has WinXP SP3 with all the updates and QT7.6.4 (I think that's the latest one). So, I can try on both to see if there are issues.
When you export as DV AVI, are you exporting as a SD (720x480?). I know that HD is square pixels and SD is non-square. The HD is 16x9 and the SD is 4:3. You could try and export your AVI as 720x540 square pixels or 720x480 non-square i.e. NTSC (CCIR 601) or try exporting as 854x480 square pixels to give your original 16x9 widescreen at SD resolution. I haven't looked at this stuff for a while, so, I'm kind of guessing here!

Drop frame rate when start saving avi file with GigE basler camera

Hello all,
I use 2 Ace basler GigE cameras at 60 fps to capture animal locomotion. I experience randomly this kind of problem. When I start to record by a start/stop button and save the videos in the hard-disk sometime the frame rate drop to 20-14 fps and a skip 2 or 3 frame. After that the frame rate became stable to 60 fps.
These are the overall settings and spec of the program:
- I use a producer/consumer loop (I never experienced a filling of the queue even when the drop frame rate occur)
- I fixed the bandwidth of the Intel 100 GigE card to 500 for each camera
- size of packet sent = 8000
- firewall disabled
- vi execution in highest mode
I observed that the dropping of the frame rate occur when the vi run for a while without interaction with the operator (the operator set others parameters in another computer, so the vi only acquire the videos without saving them)
I have attached the vi
Thank you for your help

GRAB 2 CAM SAVE AVI TTL SEND C-P LOOP 0.1.vi ‏151 KB

Alex,
Does this drop in frame rate occur with both cameras or does it only occur with the "left" or "right" camera acquisition loops. I think what is happening is that your producer loop is overwriting the images before they get written to the AVI. In addition there may be some memory conflicts as queues are generally not recommended for IMAQ Images. Here is an explanation stating that instead of enqueuing an Image Object you are actually enqueuing a memory location to an image. This means that when you produce a new image it is writing to the same memory location you are trying to read from when you write the frame to AVI. This forum offers a possible workaround.

Detect when context menu opens or closes

Is there an easy way to detect when a (righ-click) context
menu is visible? I wish there was a "visible" property for the
Contextmenu class, but there isn't one.
I've tried to listen to events to know when the menu opens or
closes but it would seem as though there are far too many
(undocumented) events to take into account and some of the events
may be OS specific.
For example, the following 3 events cover much of the
scenarios of when the menu opens/closes...
cmMenu.addEventListener(ContextMenuEvent.MENU_SELECT,
onShow);
cmMenu.addEventListener(Event.DEACTIVATE, onHide);
stage.addEventListener(MouseEvent.MOUSE_DOWN, onHide);
But you can also click either the f10, alt, esc, or enter
keys to also close the menu. There could be other ways to close the
menu, but since it is not well documented, I can't be certain.
Too bad Event.CLOSE isn't dispatched when the menu closes.
If anyone knows of a resource that documents how to determine
when a context menu is opened or closed, please let me know.
thanks! :-)

Hello,
I'm also having problems with this topic. I'm developing an AIR app that uses context menus, and I've noticed that if I bring up a context menu, mouse around it and highlight items, but DON'T select them (i.e. click off to close the menu) that the main application loses focus. There seems to be an invisible window or something blocking mouse events, until I move the app or do a command-~ (I'm on a Mac...it's as if there are multiple open windows and this toggles them.) Note that this only seems to happen in the exact sequence above - selecting an item or avoiding the items altogether after the menu pops up results in the correct (expected) behavior when the menu closes.
I'd like to be able to catch a close event of some kind for the context menu, and even better, find a way to prevent the problem described above.
Below is a very simple AIR app that will demonstrate the problem. (I'm compiling with Flex 3.4.1 framework and running it on Snow Leopard...) Much thanks in advance to anyone who can help me with this problem!

Playback dropped frames - worst when re-starting computer

I'm editing a short 3 minute project - DV-NTSC sequence - and am getting those **** occasional dropped frames during playback (not in the same place) and cannot figure it out for the life of me.
I'm new to editing and am using FCE HD 3.5
New mbp 15" 2.16, 2 Gig Ram, 160 hard drive
10.4.9
Seagate 400gb ext. drive (325gb free, FW800, Mac OS Extended, journaling off) built by OWC (Mercury Elite Pro al) w/ media, waveforms, thumbnails, etc
Settings: Safe RT, Dynamic video quality, Full frame rate, Real-time Audio Mixing to 4 tracks - low quality playback.
Canvas/viewer etc are not overlapping. Am viewing at "fit to window" size
Easy setup - DV NTSC - and all my media is DV/DVCPro - NTSC, with 48khz, 16-bit audio. Some files are anamorphic and I've changed distort and motion to make them fit 4:3.
Activity monitor shows FCE using 20-36% of CPU during playback.
Energy Saver set to Never sleep computer, Never sleep display, don't sleep hard disks, no screensaver - and am running Spindownfix. Universal Access is off. Firevault not enabled. No other programs are running
I am new to editing so please let me know if doing this could be the culprit: in some places have 3 tracks of video overlapping - not because i need to but out of laziness; in others have 3 overlapping video with a lot of keyframes adjusting opacity. ALSO: Am setting Au dynamics processor for lots of the audio - and also changing the level db in the stereo track for the same audio - should I be making these changes in the au dynamics filter instead?
Also, problem seems to be worse when I first re-start the computer - and tends to get better as I go along....?? (I assume its okay to restart my mbp without unmounting my external drive? - that it does that automatically?)
I am rendering everything (although isn't it supposed to play without dropping frames without doing so?) At one point, my project wouldn't let me render portions of audio (they were marked red, but nothing would happen when I tried render all audio or mix down etc). I trashed my preferences and that seemed to fix that problem.
I feel like I've tried everything. I'd really appreciate any advice. (Since the problem isn't all that frequent, should I consider just taking off the "report dropped frames" warning until I'm closer to a final cut?) This is a new machine, so if its a hardware problem i definitely want to get it fixed sooner than later. Thanks!

The first thing I'd try is to mixdown audio (alt-cmd-R), and see what happens.
In addition I wouldn't leave overlapping clips unused in the tracks, even though I'm not sure it makes much difference.

Final Cut Pro dropped frame rate issue

Hi there, i currently shot a short film on the canon 5d mark II 30fps and i am trying to edit it in final cut studio 2. I have recently bought the new macbook pro 15inch 2gb module.
Now the canon footage is h.264 but when importing the clips into final cut pro 6 there is a lot of dropped frame rate issues but I thought this machine could handle HD footage?
Can someone more advanced than myself recommend what i am doing wrong or a work flow that i can work with to stop dropped frame rates and render times.
Last piece of information, the project will be entered in film festivals in the spring its only a 3 minute short and i have 5 folders of footage under 4gb each which was taken from the camera
Thanks for your help.
Michael

You are missing a huge conceptual point. If the file can not spool off of the hard drive fast enough, you get dropped frames. It isn't a processor or ram issue right now, it is a hard drive speed issue. Your system drive is overtaxed trying to run OSX, applications AND spool video. It just can't keep up. Changing the graphic card isn't going to help (and how do you change the card in a laptop?)
Get an external esata drive - with the new MacBookPro you'll need an esata Expresscard34 adapter for the computer to connect the drive. Firewire is not an option with that machine and USB2 will not cut it with high data rate formats like ProRes.
When you drop in the ProRes clip to the timeline and it tells you there is a mismatch, this means your preset for the timeline is something other than your clip. You WANT ProRes and you need the sequence to match your clip - tell the program to CHANGE the sequence to match the clip.
Video is not easy and it isn't inexpensive. Time to open up those manuals and your wallet!
Good luck,

Can I chnge the context menu "open in new tab / window" options back to the previous version (reverse order)?

In Firefox 4, the context menu "open in new tab / open in new window" options are in reverse order compared to 3.6. Can this be "fixed," i.e. change the menu item order? I use this feature constantly and it's a matter of habit, also still use some 3.6 machines.

You can use the Menu Editor extension to re-arrange the menus - https://addons.mozilla.org/firefox/addon/menu-editor

Changing animation frame rate when rendering in photoshop does not change the length of the video?

I made a walk cycle animation in Photoshop CS6 and want to render it into a quicktime format. I'd like it to be 12 fps, but when I rendered it at 12 fps the video seemed to be missing frames, and the video was 3 seconds long. I have 98 frames to my animation; doing the math, at 12 fps it should be 8 seconds long. Not 3.
I was confused and for curiosity's sake I rendered the video at 6 fps, trying to really slow it down. The video ended up being STILL 3 seconds long and only maybe 20 frames. I was missing literally 70 frames. I'm so upset with this rendering thing, I could chuck my computer at the wall.
Does anybody know of a solution to this?
edit: If it means anything, I've tried rendering it straight from the frame view and the timeline view. Each time I render it I have the timeline frame rate match the rendering frame rate as well.

Photoshop CS6 and CC support two types of animation Frame animations and a Video Timeline
Changing the frame rate should not change the length of a video timeline. It should just change the number of frames that are rendered. To change the length of a video you need to change the length of the video timeline. If you increase the length of the timeline and there is audio I'm quite sure there will be a problem with it, The Video part will most likely be better then the sound. The required number of extra frames can be generated however the video may look like slow motion. If you decrease the length the motion will speed up. The length of a video is normally done be editing video clips which are trimmed and stitched together to get the desired duration. Not normally done by altering the duration of a clip.
The duration a of Frame animation is the sum of the times each frame is displayed. In a frame animation the length of time a frame is displayed can be varied it not a normal motion picture video. To have a smooth frame animation you need a sufficient number of frames that are different from each other to show smooth motion. You can use Photoshop Frame animation tween feature to have Photoshop manufacture frames to help with a smoothing the animation. Once you have a frame animation the length with the motion you want you can have Photoshop convert it to a video timeline and render a normal motion picture video. It will not have audio but you can add audio to it.

Changing frame rate when exporting from iMovie '09 using quicktime has no impact on duration. Why?

Changing frame rate when exporting from iMovie '09 using quicktime has no impact on duration. Why?
I have a file created by digitizing an 8mm film at a rate of 24 fps. I would like to create a downloaded movie at a frame rate of 15 fps. The Export using Quicktime option seems to provide that capability but the resulting file has the same duration as the original 24 fps file. How can I get the exported movie to be slowed down?

joegez,
There is a feature you can use to slow down the video. In the project, move the mouse pointer over the clip, then click the gear icon. That brings up the Inspector. Click the Clip tab. Then you will see a feature there called Speed. Move the slider to the left to slow down the clip. Or you can enter a percentage in the box on the right.
Hope this solves the problem for you.

Posterize Time VS Preseve Frame Rate When nested

Hello Every one.
When Nesting Two Compositions with different Frame Rates, I heard Posterize Time, Is a old Effect that many people use it. But It can cause Lots of problems.
So, Is It better Inside Composition Settings- Advanced: To Check Preserve frame rate when nested or in render queue ?
Thank You.

If you have to preserve the frame rate, I would just choose to preserve the frame rate. However, there are many times when you don't even need to preserve the frame rate. So, if you don't actually need to preserve it, don't.

When I right-click, the same context menu opens up (the menu for hyperlinks, with "Open Link in New Tab" and the like) regardless of what/where I right-click.

Regardless of where I right-click on a displayed webpage (NOT the menu bar at the top of the screen), be it highlighted text, a blank spot in a webpage, or anything, the context menu for a hyperlink pops up (with the options for opening it in a new tab, window or private window, bookmarking), and none of the options actually do anything even if it is a hyperlink I'm clicking on. Using keyboard shortcuts like Ctrl + clicking work fine. I haven't installed any plugins recently, and it only started a few hours ago. Wat do?

Try disabling Firebug and see how it is.

Preserve frame rate when loading one swf into another

Is there a way to preserve the frame rate of a swf when
loading it into another swf that plays at a higher frame rate. I'm
loading some flash ads that mostly run at around 12-15 frames a
second into a portfolio site that runs at around 40 frames per
second. All my ads play too fast. The link is:
www.dg8tal.com/portfolioidea.html
Thanks!

As far as I understand it, there is no option to override the
frame rate designated by the main movie you are loading into. The
SWF file you are loading always inherits the framerate of the SWF
you are loading it into. Here are some suggested work-arounds that
might help:
1) Lower the frame rate of the main movie on the website that
you are loading into.
2) Expand the timelines of the advertisements just for use in
your portfolio
3) Put your menu and thumbnails in one HTML frame that can
then load each item in another HTML frame above it. Since each SWF
would load on its own, the framerate of your main swf would not
matter. You would lose your nice resizing effect though unless you
did some more complicated integration with javascript I imagine.
I would recommend going with option 2, since that will take
the smallest amount of work while preserving your overall design.
However, with the faster framerate, your advertisements would have
difference performance characteristics that you'll need to assess.
I'm trying to think of more options, but these seem to be the
first things that come to mind.

Dropped Frame Errors When Time Remapping DVCPRO HD 720p60 Clips

Wondering if this is common due to FW800 throughput limitations or abnormal behavior.
I'm editing several DVCPROHD 720p60 projects and cutting them in FCStudio is like butter on a Dual 2 G5 connected to a FW800 G-Raid. I needed to time remap a clip and lo and behold, some dropped frame errors. Recreated and retimed several times with the same error. Dropping down the playback quality fixes this but wondering if it would be a normal occurance to see this with DVCPRO HD footage.
Any thoughts?
Dual 2 G5, 17 & 15 PB Mac OS X (10.4.7) Monitors, G-Raids, and Cameras, oh my!

It may be normal... a lot depends on which machine you're using, but If it drops frames, render it...

Right click context menu opens then closes quickly in Finder

After my upgrade to Snow Leopard, I now have a problem with Finder. When I right click on something to get the context menu, sometimes, it works fine, and others, the contextual menu shows up for a second then closes. The only way I can select any of those options is to right click and hold, then select. This is getting annoying.
It seems like maybe a corrupt preference? Anyone seen this before or have an idea how to solve it?

I knew I wasn't alone! This has happened with my install of Snow Leopard as well. The only difference is that this started happening immediately after the install and I did a fresh formatted install, not an upgrade.
I made a short video about it here:
http://qik.com/video/2742618
Any help on this would be appretiated. It seems like this isn't too widespread an issue, but who knows. People might not be piping up about it. It is incredibly annoying, however.

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!

AE CS6 on Windows8: H.264 Coded generated very strange frame rates when rendering

funny things are happening:
I import 300 jpegs (canon 6D raw exported from LR as jpeg at max quality)
create a new composition (with 25fps)
render video in h.264 @25 fps
videos rendering works fine, plays well at external player.
drag and drop video from file explorer to AE project window:
framerate: 0.081
how does that happen and more important: how can this be fixed?
even more funny: until using 200frames to render, frame rate ist at 25fps,
having more frames in the video, framerate goes down below 1 close to 0...
is there some know issues with the h264 codec in ae?
thanks
Claus

Definitely. If you use a temporal (time based) codec like H264, the Render Queue will create inefficient results, as it can't look ahead or behind while it renders. AME can, which means you get superior compression results.
If you need to render from the Render Queue - for example, if you're rendering multiple output segments and formats in one pass - then use an intermediate codec, then convert to H264 later using AME or any other decent compression tool.
