Full screen firewire preview... before capturing

hi there. i'm new here. i'm trying to find a way to connect a cam to my mac and be able to have full screen live feedback and then (as seamlessly as possible) start a pre-recorded material of the same situation. this is for a performace i'm tryin to put together for a festival.
i suppose it's a sort of composite using live and recoded material..
anyone any ideas.... thoughts..... anything???
thnx a million

May simply be a compatibility issue with whatever graphics card you are using and/or Apple's Cinema Desktop stuff in a more general sense... pöerhaps Dave and Rick can shed some light on this. I'm not a Mac guy, after all...

Full-screen (spacebar) preview quality testing

[For background story, please read http://forums.adobe.com/thread/1056763 but be warned, it's very l-o-n-g!]
In brief: some people have noted that Bridge full-screen (spacebar) previews (FSPs) don't accurately reflect the sharpness of a photograph. Sometimes this can be explained by individual configuration problems, but it's clear that this is a common issue amongst people using Bridge to assess/score photograph sharpness, without having to build/examine 100% previews for every image.
[It's worth noting that one common reason why FSPs aren't very sharp is because the Bridge advanced preference "Generate Monitor-Size Previews" hasn't been ticked, as this produces a higher resolution image cache. Another cause of very fuzzy previews is random and unexplained, but can usually be solved by restarting Bridge and/or clearing the cache for the selection.]
This discussion concerns the lack of sharpness seen only in FSPs. It can be described as "a subtle but significant loss of detail and sharpness, similar to a slightly out of focus photograph"; imagine a photo with a little bit of blur filter, or a Photoshop PSD at a non-standard zoom setting. This "softening" of the image is caused by Bridge asking the graphics processor to resize the image cache to fit the display. If you select the Bridge advanced preference "Use Software Rendering", you can improve a poor FSP slightly, at the expense of speed, by bypassing the graphics processor.
The test
Visit this web page and download the last image ("2362x3543 pixel, 4.5 Mb") to your computer.
Browse to this image in Bridge, and view it full-screen by pressing Spacebar. Take a screen capture, and save it as a TIFF or PSD.
Adjust your slideshow settings (Ctrl/Cmd-Shift-L), picking "Scaled to Fill", then click on "Play". Save the screen capture, as above.
You now have two screen captures: one FSP, and one cache JPEG reference shot. Examine them side by side at 100%, or layer them in Photoshop and use the hide layer button to flick between images. Pay particular attention to the two left-hand photos, the sharpness check text, and the converging lines.
Make a note of your computer's operating system, graphics processor and driver version, as well as your largest display's pixel dimensions.
Post this information below, together with high quality (10) JPEGs of both screen captures, labelled FSP and REF, and any observations, so we can all see.

OK, it usually takes me a while to let the penny drop, especially when it comes to maths...
I also am busy with the transition of my new Mac pro but with al this here are my results. I include several screenshots but due to upload limit of 2 MB per image in here I downsized the original screenshots a lot, but hopefully it will be clear.
For full screen screenshots I have the asked FSP and REF but also the 100% preview in Bridge with space bar and click. Don't know what your file size is but using EOS 1Dx with 18 MP CR2 files (converted to DNG) it does take me about 1,5 - 2 seconds for both loupe and FSP to build a 100 % preview, and I seem to recall this was not very different behavior on my previous (6 year old) Mac Pro.
You are right (of course... :-) ) regarding the difference between FSP and REF, when studying closely there is a significant detail difference between the FSP and the REF. However, only the 100 % preview matches the original jpeg. The FSP file is on closer look not so good with details but the REF file is only slightly better, both are not correct and therefor the 100 % is still needed.
Here is the FSP screenshot:
and here the REF screenshot:
also the 100 % preview in full screen screenshot:
and finally a composed file with details from original, 100 % REF and FSP:
As said before, at first sight I can't spot significant difference between all options and the full screen (as the preview panel HQ preview) let's me spot the vast majority of unsharpness issues, hence my multiple rounds of sorting and incases of doubt the 100 % option.
So while your theory is correct I'm afraid I (still) doubt the usefulness of this all. If neither the FSP and the REF (although the latter does show a bit better result) can match the results of the original but the 100 % does it well I don't see an easy solution for improvement.
I agree with the quality from the screenshots Curt provided, but Curt also uses the embedded thumbnail instead of HQ preview option. Depending on his needs and hard ware availability it would be nice to see new results with the HQ and monitor sized previews options enabled.

Vertex Array Object deleted after full screen RAM preview

Hi,
I'm writing a plugin where I use OpenGL VAOs. Everything works fine, also RAM preview, but when I cancel full screen RAM preview and render a new frame the VAO is somehow deleted. I called glGenVertexArrays for testing and the handle it returns is 1, which was previously the handle of my valid VAO.
Has anyone had this problem? It only happens when using full screen RAM preview. I also tested this in the GLator sample by generating dummy VAOs and it's exactly the same.

Hi Rick,
Thanks for the reply.
I've changed the .mp3 file to a .wav file and that seemed to fix everything, for the time being...
It previewed for 10 seconds fine, but after about 15mins of working on this the RAM preview area has started to shrink again and it's only previewing just over half (5 seconds).
I changed my memory and allocated 4GB to other apps, also turning off rendering multiple frames... (by the way for some reason I can't get my 'actual cpu's that will be used' to change from 0? This seemed odd). Still no change.
I've attached a screenshot of my comp details below, along with a shot of my screen when RAM previewing... (you can see the green bar does not go all the way). I'm not working with ANY footage which is why this is most peculiar, just the wav file so I can edit to the beat.
Once again if there is anything else you can think of...

G4 ti4400 video-in preview before capture

HElp can anyone tell me how to simply PREVIEW video BEFORE I capture to my hard drive?! Id like to just be able to watch video from jvc camcorder on pc. Capture does work w s-video or firewire card i have installed. Do I need a Tv tuner card ? I would assume its possible to JUST WATCH video without having to save it to hard drive first.Running wxp, win movie maker and winproducer installed. THNX

Okay, could be other issues.
What exact versions of OS / FCPro / QT?
Has this procedure been functional in the past?
If so, did you do any recent upgrades/updates?
FireWire NTSC Basic is usually used for Canon hardware, due to funky FW implementation. You might try changing it to standard FireWire NTSC.
I notice the Pana AD-DV2000P is on the list of qualified devices for Final Cut Studio 1 (FCP 5).
http://www.apple.com/finalcutstudio/resources/devicelist.php#results
That deck is not listed for FCS2...(one of the reasons for my first question above)
Another reason for question #1 is the possibility of a bungled QT install (incompatibility between OS/FCP/QT), so your answers will help diagnose the issue at hand.
You might try the 'Guinness Solution', posted by Studio X, here...

Post back with more info, then maybe try the Guinness approach.

Full Screen Preview Choppy/Freezing

Ok I saw another post similar to this one, but it didn't seem to be exactly the same issue...
I recently started having a seemingly random issue with my external monitor. What happens is when I am previewing a movie, the preview window IN Final Cut works just fine, but the external monitor (where the video preview is full screened) shows the video for a second, then becomes really choppy, then freezes completely. All the while the preview window in FCP is still showing the video just fine. I have tried buying new Mini Display adapters (I've now tried both DVI and VGA), I bought a new DVI cable, a new VGA cable, I hooked it up to other external monitors, and it has the problem every single time. I also recently discovered that if I switch the video playback to "Desktop Preview - Main" (where it simply full screens the preview on my laptop screen) it has the same problem! Also, my external works fine in every other regard, only previewing has an issue. And this came out of nowhere! It was working just fine, then suddenly one day this was happening. Oh, and I have tried FCP 6.0 AND 7.0, both of which produce the same result... It was also suggested I mess with the timeline video settings and so far that hasn't proved helpful either.
I am using a MacBook Pro 10.5.8 - 2.4GHz Intel Core 2 Duo.
And like I said, I haven't changed a thing that feels like it would make this happen. It just suddenly stopped working...

Sounds like maybe it could be some sort of issue with your video card. NVidia, GTX, Radeon? Anyway, I would run a test using some a firewire I/O box. See if the problem persists sending to an external monitor from an AJA or some other breakout box.

Satellite A300-20P - Games with Windows 7 not working in full screen

I have Satellite A300-20P and VGA ATI 3650
I made upgrade to Windows 7 Professional
All games working well but not in full screen. I installed the last driver for ATI for Windows 7. It was working in full screen in Vista before I make upgrade.
Same problem on my brother`s laptop after he make upgrade to Windows 7.

Hi
Normally you can change the screen resolution in every game and if they should run in full screen mode or not. Check this!!!
Can you also tell us what display driver you have installed? The drivers from the Toshiba page are for desktop cards and not for mobile cards. So please use only the Toshiba drivers.

Full screen vertical scroller sometimes works, sometimes doesn't

Curious to know if anyone else has had this problem or there's some information that my elucidate this mystery:
Our publication ran a page with a full-screen vertical scrolling overlay today for the iPad. Inside of Viewer the folio flipped from page to page just fine, but once published we were unable to move between pages any longer once on this particular page. We've run full-screen vertical overlays before without incident and we're stumped to understand why the Viewer elicited no issues while the final publication did.
I put this question to you, Forum: Any thoughts?

Full screen images on page?

I would like to have full screen images on a page that fits to most browsers. I don't know what would be the best width in order to acomplish that.

Hi. I am also trying to have my images appear full screen when previewing in a browser. I realize you can do this by adding an image to the
background of your Muse Document. However, this is NOT what I want to do. Here is a link to website where the images appear full screen,
no matter how you size the browser window. http://www.lexusls.asia/ I too would like my images to appear full screen when appearing in
a browser. I have also included an image of what I am getting when I try this. See how the city image floats in the middle? I want it to fill the
entire screen when viewing in a browser.
Thanks to all who may reply.

Minimizing compose windows in full-screen mail under Yosemite

How do you minimise the compose window when mail is in full-screen mode? Before Yosemite you could click on the full-screen button in the top bar, and get mail out of full screen. That was a lousy solution, but it was working. Now it's not possible anymore. So how do you do this?
This is a seriously annoying bug.
Thanks!

I am also having this issue. However, it is not consistent. I installed Lion a week ago and it started off working fine. Only in the last couple days has it started doing this.
Running the first aluminum unibody MacBook from 2008, 2.4 GHz Intel Core 2 Duo Processor, 2GB 1067 MHz DDR3 RAM, 500GB WD Scorpio Blue SATA HD, everything else stock.

HT3771 Previewing a document in full screen before printing?

How do i preview a pdf doc in full screen before i print it (or any document for that mater)?
I need to check that i can see all the pages before i print it, as i am printng 6 slides on one page.

Welcome to Apple Support Communities.
There are lots of useful tool 'buttons' available in Preview that are not included in the default toolbar.
Open a multi-page document in Preview, and then select Tools, Customize Toolbar.
I find Print, Actual Size, Zoom to Fit, and Page (number) to be useful when viewing, editing, and printing multi-page pdfs.
Be sure to drag the lower left corner of the pdf Preview window to full size or click the double-arrow to see all the tool buttons you've added.
If you view a multi-page pdf with the Sidebar visible in the right column, you'll have the advantage of seeing page thumbnails and still able to check the full-size document in the left window.
I use the Actual Size button to quickly zoom the left window, but you can also click the '+' button to increase the document to 100% size, to verify the contents of each page.
Clicking the 'Print' button seems to take away all of that, showing only a thumbnail of the each page again.
BUT...
click the pdf button at the bottom left of the screen, and select 'Open PDF in Preview'
I know this seems redundant, but it reopens the document in a scrollable (6-image per page) view where you can still zoom AND has a 'Print' button at the bottom that will start the printing immediately, once you're satisfied with the result.
Hope that helps.

Monitoring full screen HDV over firewire from camcorder

Hello,
I am a recent switcher from Windows to Mac. One thing I haven't figured out how to do yet on my Mac is to simply use my MacBook Pro screen to monitor (in full screen) the HDV video that comes off the Firewire cable of my Sony camcorder.
On Windows XP, I used to use VLC for this. I posted a message a few weeks ago asking for help with this on my camcorder's forum:
http://www.sonyhdvinfo.com/showthread.php?t=13728
but haven't gotten any solution yet.
The thing is that the Mac version of VLC doesn't have the 'Open from Capture Device' feature that the Windows version does, and I haven't been able to figure out any other way with Final Cut or Quicktime on my new Mac to do this.
Again, I simply want to MONITOR full screen the HDV video that comes off my Sony camcorder's firewire. If I use the logging tool in Final Cut, I only get a small preview window (which I can't seem to get full screen). Same in Quicktime. Of course I can CAPTURE the tape to Final Cut and then playback full screen, but that is a step I'm hoping to avoid.
Do you Mac folks have any other tricks for doing this?
Thanks for the help!

Thanks for all your replies, but I still haven't found a solution for this one:
@Red Door:
It looks as you might be right! Thanks for confirming what I've found to be true: this may not be possible on a Mac!
@Studio X:
Thanks for this idea. I already do this when I have a HDTV available. But the idea here is that I'd like to be able to use my laptop monitor for this when I'm on the road (and don't have an HDTV, or the HDMI cable, available). As I said, with my Windows laptop and VLC this was a great solution to monitor my HD camera when I'm on the road with just my laptop and camcorder. Its a shame I can't get my gorgeous new MacBook Pro with the beautiful almost-HD resolution monitor to do this!
@Thomas & Andy:
Thanks for these recommendations .. they almost worked! I tried both and neither quite did the job. BTV looks like a really old program (last release 2002?). It looked promising, but alas couldn't get it to recognize my HDV camcorder.
Monitor Magic looked even more promising, as it is a new piece of software specifically made for this purpose. Indeed, it did recognize my HDV camcorder no problem, but alas it still couldn't do the job. First, you can't monitor full screen! (That's my whole point.) Additionally, I didn't get any sound and also the video quality was really poor in the preview window. No way to deinterlace and lots of dropped frames. I got a better preview window out of Final Cut and Quicktime.
Anyway, thanks for your recommendations but my search continues! (At least until a better version of VLC for Mac comes out!)
I remain really surprised how hard this is to accomplish on a Mac! Macs have such a good reputation for video/media editing. Regardless, this was pretty tough to get working on my Windows laptop until I discovered VLC.
Thanks again!

Can't check photos to import in full screen preview

Hi All,
Bit of a frusting bug, unless I misunderstand it, but when I import photos using Aperture from a SD card, I can only do so in the tiled view (max 9 photos to a screen on my 21" Mac)
I'd much prefer to select the files to import in the much larger single photo view so I can see them better before deciding to import.
As in the screenshot above, there is a check box in the single photo preview, to the bottom left, but it doesn't seem to do anything. Only photos checked in the list or tiled view are added to the photos to be imported.
Any ideas why this doesn't work (or what the check box in the single photo preview is for if not this??)
Thanks in advance.

Just to be clear, it might be easier to screenshot!
I tick the checkbox in the large import preview - notice the import checked remains greyed out - it doesn't recognise it:
If I then go back to the grid view. The photo is still checked, but Aperture still doesn't recognise that it is to be imported:
However, if I stay in the grid view, remove the tick and add it again, Aperture import does recognise it and adds it to the import list. I can now use the import button.
Not the end of the world obviously, but when going through hundreds of photos, it would be very handy to scroll through full screen previews with the arrow keys so I can see them better and check them to be imported as I go.

I have a new Macbook Pro. When watching Youtube videos, it works perfectly until I attempt to watch the video in full screen. When in full screen, the video freezes immediately and the audio continues. When minimized it works fine as before. Help?

I have a brand new Macbook model A1502. I am taking online college classes that incorporate youtube tutorial videos. I can watch the videos if I don't maximize the screen to full screen. When in full screen, the video freezes immediately and the audio continues uninterrupted. I can press escape and go back to the previous screen and the video continues to play with no problems. Can anyone help me please? This machine is literally just out of the box with maybe an hour of use. Thanks in advance

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Playback only stutters in preview screen, not full screen.

Brand new iMac 5k, maxed processor and graphics driver, and loaded up with 32gb of ram. Files live on internal 1tb drive. Originally 1080p 30fps MP4 with h.264 codec. Have created proxy, have optimized, have used compressor to switch to prores format. The files play, freezes, then plays again and freezes. Occasionally I get a dropped frame alert when playing on timeline or when previewing original file. Files do not stutter when doing full screen playback! I have turned on and off background rendering also. This is my first foray into FCPX so any help is appreciated. Timeline is set to match the frame rate of clips when I load it in. Beta testing the new Yosemite, could that be it?

Same here. I sent feedback to Apple since this stuttering didn't occur for me before the beta. I suggest you do the same.

Full screen preview in AE CS6

Hi everyone,
I'm testing the CS6 trial right now before to purchase, and I'm wondering how can I get Full Screen preview on a monitor.
I just swithed to Lion on a Mac Pro, with 2 graphic cards. I have 2 monitors for my user interface, and I have a great third monitor with Color Space management feature. This configuration was working last week with Snow Leopard and CS5.5, but not anymore with Lion and CS6.
Why?
What I was doing: I was diging into Preferences/Video Preview, I was selecting Computer Monitor Only, and from there, in the Output Mode I was able to select my monitor.
Now when I come here, in CS6, it's grey and I can't select anything there...
Any idea?
Thanks in advance

May simply be a compatibility issue with whatever graphics card you are using and/or Apple's Cinema Desktop stuff in a more general sense... pöerhaps Dave and Rick can shed some light on this. I'm not a Mac guy, after all...
