OpenGL ES and Screen Capture

Aloha...
I have an app for the iPhone that utilizes a number of different views including two views that are openGL views. The program also has the ability to take a snapshot of the screen and store it to the photo album.
If I snapshot my non-openGL views, everything works properly. However, if I snapshot any of the openGL views, any non-openGL components are captured properly, but the openGL image itself is black (in this case, there is a non-openGL frame around an openGL animation... the frame gets captured perfectly, but the animation is missing).
I am using the following code to capture the screen:
screenRect = [window bounds];
UIGraphicsBeginImageCOntext(screenRect.size);
CGContextRef ctx = UIGraphicsGetCurrentContext();
[[UIColor blackColor] set];
CGContextFillRect(ctx,screenRect);
[window.layer renderInContext:ctx];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UImageWriteToSavedPhotosAlbum(newImage,nil,nil,nil);
UIGraphicsEndImageContext();
Again... non-openGL graphics are captured and stored properly. Any openGL rendering does not capture and the space it takes up is blank.
Thanks!

In my case I wrote a custom exporter for C4D which outputs all of the mesh information which my code then reads in. The X-File format is okay but there is a **** of lot of information in those files that you don't need and will end up taking valuable space - especially if you are working on iPhone.
The Milkshape format is pretty simple to read but if you are looking for an okay source on this kind of thing take a look at: http://www.amazon.com/Focus-3D-Models-Game-Development/dp/1592000339

Album and Screen Captures

Minor annoyance:
When you take a screen capture and you want to crop it, to send it (or do anything to it), you press on it and the Tap To Set Location menu etc pops up. The probalem is that the menu pops up up ont he top and bottom, but the picture itself does nto shrink to fint.
So what you have is a picutre, in which you cannot see the top or the bottom and it makes it harder to figure out to figure out if this is the right picture if the top and bottom are important.
Solution:
Can sony make it so that when the Tap To Set Locaion and the top portion of that) menu pops up, the picture shrinks to fit within those fields?
A lof of the other photo processing applicaiotns already resize to fit the screen, so that any menu that pops up, doe not actually block any part of the picture you are looking at.
Thank you.

The bars are semi translucent.. they have some icons on them for actions such as delete, set location or send as sms ect.. They do block the top and bottom.
I cannot see the clock in the top right cornver of the screen shot, for example.
When the menus pop up, the clock on the screen shot gets replaced with the current clock and the current battery life etc. (same info as on the screen shot, but current, not from the time of the screen shot)
Does that make sense?
I have to assume this is a general Sony Album behavior, not limited to Z1C

Flicker removal on horizontal lines and screen capture text

Hi All,
I often have to include a PC screen capture (such as an Excel screen) in a video. How do I minimise the amount of flicker when playing back on a CRT.
I understand the problem is in the interlacing. I have tried the anti-flicker filter and this just seems to make things softer without much improvement in the flicker.
I have seen a post which recommends using progressive frames for still images but does not explain how to do this.
Any assistance gratefully received!
Regards,
Duncan Rosie.

> If you are making NTSC projects, keep within the color gamut (15-235).
That should be 16-235. And, assuming you are working with RGB files, Premiere and/or Encore will automatically scale the RGB to fit within the 16-235 luminance range. PAL also uses the same legal luminance range. It is not exclusive to NTSC.
Here is decent trick -- it may not eliminate your flicker, but it will greatly help offset the severe blurring that occurs when applying Anti-flicker or variants of this technique (such as a vertical gaussian blur) to screen captures of GUIs, spreadsheets, etc.
1.) Open the screen capture bitmap file in Photoshop and scale it to exactly 200% using "Nearest Neighbor" resizing
2.) Bring that file into Premiere and use Motion to scale it to fit (scale with be 50% of what it was before you resized it)
3.) Apply Anti-flicker filter as neeeded
The nearest neightbor resizing method makes for "blocky" resizing that is horrendous with photos, but it ideal for screen captures -- so long as you only scale by 200%, %300, %400, etc.
This generates "extra pixels" by replicating exisitng ones that will help:
a.) The appearance of the image when scaled to compensate for aspect ratio
b.) Maintain better legibility even when strong softening filters (such as Anti-flicker @ 1.0) are applied
c.) Allow for tighter zoom-ins of your screen shots while maintaining relatively sharp edges

Screen Capture won't capture window

Hello, I'm using Snow Leopard on a Mac Mini with a single monitor. When using the screen capture keyboard commands, I can do everything except for capturing a window. I'm supposed to be able to hit command+shift+4, and then spacebar, and the pointer will change into a camera that will capture only the window I click with it. I recall being able to do this a long time ago, before I upgraded to Snow Leopard. I also use a widget called Screenshot Plus that acts as a front-end to those keyboard functions.
When I try these days, the cursor changes into a camera, but the entire screen is highlighted as if it will be selected. When I click, what gets captured is a blank white area the full size of my screen. The Screenshot Pro widget produces the same incorrect result.
I've seen another discussion about this topic, but it seemed to center on the Grab utility. On my system, Grab works correctly, including the window capture function. So I have a way to get the results I want, but I would be interested in a solution that allows me to use the keyboard method again. Thank you.

Noondaywitch, I created a test account and screen capture of windows worked correctly in it. Thank you!
So now I need to look for something about my account. I'm going to try disabling all startup items and see what happens.
UPDATE: Disabling all startup items and rebooting fixed the problem. The window capture function now works in my user account. Now I can put startup items back one by one to see which one might have caused the issue.
Thanks to all who gave advice.

Expression Encoder Won't Screen Capture Sims 4

The program works, because my recording shows everything happening on my screen until I hit the icon to start Sims 4. After that point, I just have a large, blank, white window, with a white cursor moving around through the blankness. What's
going on? Why won't it record what I am doing in Sims 4?

Screen capture failed

We recenty got a new iMac at our house, but there are a few problems. We went through the setup, and transfered all the files from our old iMac (an old flatpanel with the dome hard drive underneath the screen) which was running Mac OS X 10.3.9. Now there seems to be a problem with Screen capture.
We also recently bought another family member a new iMac (22" iMac 2.2 GHz [?] 1 GB Ram w/ Mac OS X 10.5). That computer came with Mac OS X 10.4 installed, but came with a 10.5 CD. We did a normal setup without trasfering any files, and Screen capture works fine.
Details:
When I try to use screen capture, I get a message saying
"*Screen capture failed*
The attempt to take a screen capture has failed. The
error is: 'Unable to create type string.'"
Any solutions?

Open Disk Utility, select your system drive (I think by default, they are named "Macintosh HD"), just select whichever drive is your OSX one, then click REPAIR PERMISSIONS.
It will take some time to complete, particularly if you haven't done it in a while.
Also, you should do this BEFORE and AFTER any installation that uses an INSTALLER.
And like I said before, it's kind of a "Odd things 101". Lots of little weird behaviors can be remedied by using it.

How do I connect two video cameras to my computer have them both show up on the desktop at the same time so I can see and capture both images using a screen capture program?

Hello,
I am a teacher and want to make some videos to post online for my class. I would like to have it set up so that I have a powerpoint presentation going, a video camera pointing at a piece of paper I can write on and another video camera pointing at me. How do I do this? I have seen several solutions but they seem to be for switching between videos whereas I want both video images to be on at the same time.
Also, is there a screen capture program you would recommend?

Go to System Preferences - Sharing and change the computer name there. You can also, optionally, change the name of your hard drive to further clarify the origin of your backups. Click once on the "Macintosh HD" on your desktop, then click its name to allow you to edit it.

I have a 17" Macbook pro with flickering red and cyan(blue) lines across the screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem.

I purchased my Macbook (17") through a certified apple tecnition in August 2012, it was refurbished and the motherboard was completely replaced. I do a lot of photo editing, but I have been unable to do so because of the red vibrating lines that interrupt my screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem. I brought the computer back to the technition I purchased it from and he said that it was a problem with my fan, so I have two new fans but the issue is still occuring. He says he doesnt know whats wrong. Does anyone have any information on this issue?
Here is an image of the issue
http://www.flickr.com/photos/67839707@N08/8884847081/

I recommend having your Mac serviced by someone competent. A force sufficient to "blow apart" the fans was clearly excessive and may have damaged the display cable, as well as any number of other problems.
Dust is properly cleaned with a vacuum, preferably one designed for computer service, and they are not cheap.
Compressed air should never be used. It just blows dust everywhere, often into places where it can no longer be removed.

CRASH REPORT Product: Adobe Photoshop CC Application running on: Apple iMac 3.5GHz / Mavericks 10.9.2 Application crashes without warning. . Symptom: Drop down boxes go blank white (I shot screen captures of blank drop down boxes) and application

CRASH REPORT
Product: Adobe Photoshop CC
Application running on:
Apple iMac 3.5GHz late 2013 / Mavericks 10.9.2
Application crashes without warning. Symptom: Drop down boxes go blank white (I shot screen captures of blank drop down boxes) and application stops working, actions for appox. 10 minutes preceding crash are lost. Force Quit required to quit unresponsive / frozen application and then Restart of Adobe Photoshop CC
Crash Frequency: Three time in this work day, 5.6.14 Once a day sporadically (approximately 10 times) in past two weeks.
Other applications running at time of crashes: Adobe Bridge - NOT effected. Computer was on line with no browsers open.
Otherwise computer continued to operate normally.
I have been using Adobe Photoshop CC for approximately two months.

Thanks, Chris,
I hope that this is the solution.
re: "And a crash report without an actual crash report (a long, detailed text document available from the crash report dialog), is not all that useful" :
I did in deed submit a homemade crash report.
I would have submitted "an actual Crash Report " and sooner, but: When this event occurs. there are NO dialog boxes. All frozen / blank. No possibility of "actual crash report" !
Thank you!

How to Get Proper Video Screen Captures (Screencasts) of Photoshop and Lightroom in Win?

Hello. I would like to get proper screen captures of Lightroom and Photoshop on Win 7/64, showing all screen elements as you see them. I tried FastStone Capture 8 and SnagIt 11.1, but they have various differing issues. Do you have a good hint?
What's more: In my screen capture, i also want a mouse-click-sound each and every time the mouse is clicked. This is not "system audio", because the computer doesn't play a sound for every ordinary click. The capture software must add that sound. (I'm aware i can add the sound manually in post production, but want it recorded together with video.)
Experience with Faststone Capture 8's video captures:
I get well usable footage
Does optionally record mouse-click-sound for each click, with adjustable volume
Does not properly record some elements of Photoshop or Lightroom screens:
- cursors sometimes look rough or double-sized
- Lightrooms "TAT (Target Correction Tool)" disappears while being dragged on the image
- the color selector box of Lightroom's Adjustment Brush is not shown, while the cursor working within that color selector box is shown
- Lightroom's three-second-splash-message after Undo etc. is not shown
(All these missing elements do show up in *still* captures with Faststone Capture. They also *do* show up in video captures done with SnagIt, see below)
Experience with Snagit 11.1's video captures:
Does properly capture all those elements that FastStone does *not* capture (listed above)
Does *not* optionally include a mouse-click-sound for each and every mouse click (they record "system audio", but a sound on every click is not "system audio", so a regular click on a menu item has no sound)
Videos are less smooth, cursor sometimes "jumping"
Now, do you know a screen capture software for Win 7 that can
properly record *anything* that's seen within Lightroom and Photoshop
and automatically add a mouse-click-sound for each and every click i do
and produce smooth footage without "jumping cursors"?
Thanks for your real-life experiences!

Myles, thanks again, here are my findings with Camtasia:
Camtasia:
DOES record overlays like adjustment brush's colour selector
.camrec format isn't offered for recording, only .trec and .avi (on Win 7), but trec is usable just as .camrec i guess
Exported MP4 looks blurry and has colour blotches, that are not visible in the initial recording, only after exporting; this doesn't change at all after setting very high quality MP4 options; i guess i didn't look properly
i see how to add mouse-click sounds; i don't like the sound they provide so much; maybe it can be exchanged.
Other tests:
Camstudio:
mouse click sounds very weird (my mistake?)
does NOT record LR overlays like adjustment brush's colour selector
Screen-cast-o-matic, optionally online, free version:
DOES record overlays like adjustment brush's colour selector. Mouse-click-sound not in free version. "System audio" is promised in paid version, but that does not necessarily mean a sound for each mouse-click. Contacted support for more
Straightforward using, lots of short video tutorials (useful for absolute beginners).
Free downloaded program 1.4 only works on primary monitor, the online launched app also records on secondary monitor
Don't see option to record a "window", only set resolutions
More "jumpy" than Faststone
More interesting pro-version seems to be rent-only-licenced, at 15 USD per year, not a one-time-buy

Version 8.1 Can't Activate, Can't Update, Can't create/export NX *.prt Files to 3D PDF. Screen Capture feature does not properly represent Model/Bodies. Printing from NX does not recognize Adobe Acrobat 3D as a printer to try and export.

Version 8.1 Can't Activate, Can't Update, Can't create/export NX *.prt Files to 3D PDF. Screen Capture feature does not properly represent Model/Bodies. Printing from NX does not recognize Adobe Acrobat 3D as a printer to try and export.
I was able to register it though.

Not a surprise. The Acrobat 8 product family passed into End of Support back in 2011.
Be well...

Premier Pro CS4 and Camtasia imported screen capture

I have a question from one of you professionals regarding Camtasia screen capture video imported to PP. I used several settings that was suggested in the posts in these forums and others and the quality of my video is still very bad. Please Help:
I am making a four minute training video that includes some screen shots of software. The final video will be put on DVD and Flash for website.
My capture settings of Camtasia are 1024 X 768. I used Tech smith codec and I used Logarith codec to produce the video in AVI from camtasia.
I set my PC screen size to 1024 X 768 as well.
My Premier Pro CS4 Setting HDV 1080i, 29.97 frame rate. 1440 X 1080 Frame size.
I also used the following frame sizes DV NTSC, 29.97 frame rate. 720X480 frame size
I also used MPEG2, HDTV 720p, 29.97High quality, 1280 X 720 frame rate
None of the above settings worked. Please help
Thank you

This ARTICLE and the included links might be helpful. Be very sure to look at all of the replies by Jeff Bellune on using the TechSmith CODEC's from Camtasia. I think that he replied in most linked threads.
Good luck,

How can I change the screen capture default filename and location?

AS3 and AS4 screen capture keystrokes create badly named files in a bad location, i.e., picture1.png, picture2.png, etc. on the desktop. This is silly, as it creates un-differentiable files. I would at least like to change the filename template, and at best also the location that they go to, but I can't figure out how to do this, if it's even possible. (The filename should have a timestamp, not just a sequence number, for example: picture_200911181234.png or whatever -- pretty much anything but a simple sequence number!)

Use TinkerTool to change the download location for the screenshots. However, AFAIK, you're stuck with those names unless you a folder action to the download location such that it will change the names according to some scheme you devise. For that, try a google search for *folder actions mac*.

Lion, Quicktime Screen-capture, and Photoshop

I've used Quicktime's screen capture tool to create Photoshop video guides in the past and it's produced really high quality, high fps results in a small file. However, since I've upgraded to OS X Lion, my entire computer is brought to its knees during a Photoshop recording session. As soon as I hit record, boom - Photoshop becomes really choppy and it's almost impossible to create a decent video.
Could anyone else here with Lion do a quick test to see if you get the same results? Just open up a Photoshop file, open Quicktime, go to New / New Screen Recording, and see if you're able to use Photoshop without any performance drop.
I'm running CS5 on a dual quad-core mac pro with 12 gigs of ram. It's about 3 years old, but I shouldn't be running into a performance hit like this.
Any feedback on your own experience or tests would be greatly appreciated.
Thanks!

Under OS X "Lion," every screen capture tool I have (Snapz Pro X, Screenflow, Layers, iShowU HD Pro) will no longer capture a DVD frame—if the DVD is being played by Apple's DVD Player. The resulting screen cap shows a "transparent" window. VLC still works in that regard. I've also noticed that the iTunes app no longer has a free-floating video window, which was always my preference. Videos now show within the boundaries of the iTunes window, or full-frame. One more note on Apple DVD Player is that invoking full-frame playback will slide in a new "space" with a background similar to that seen on iPads or behind the Desktop Widgets.
I realize capturing DVDs is not what you're trying to do, but all of the above indicates a complete change to the way OS X handles any streamed video. I have yet to make a test, but I suspect that output-to-NTSC through monitor ports may also be inhibited for certain things; Apple may be plugging the "analog hole" with software. My guess is that whatever background routines are responsible for this may be sufficient to slow the frame rate of your tutorial captures—in the same way that heightened security at airports now significantly slows boarding procedures.

Screen capture and PNG format?

Hi,
When I use the screen capture feature (SHIFT  4) I always get a *.PNG file. Is there a way to setup the screen capture to a JPG file format as default?
Thanks

I dont think so. I know that the Grab utility can save as TIFF, but I am not aware of it being able to save as JPEG.
However I believe that you can use Preview to export the screen image to a JPEG file. However this is not exactly what you want.
I know OSX has some frustrating features, and in some areas and ways I miss OS 9. But then again screen capture to JPEG was not available in OS 9 without third party software.
