Why Block Video Output?

I have just purchase a brand new shiny Yamaha AV amp and Yamaha iPod dock (which was supposed to be video compatible) with the hope of using the on-screen facility to select music tracks. But oh no, thanks to someone in Apples ludicrous decision to block video output unless you're using Apple's own dock and cables I can’t!
Apple - please unblock this ridiculous restriction!

Hi,
I'm not condoning it, but in my estimation this will not change. Apple implemented this to secure the video so that they could reach the agreements they have with the film companies regarding online purchasing and rentals. If the limit is ever officially removed I'm sure Apple would lose the iTunes Store content overnight. It's for this reason that the first video iPod (the fifth generation) can accept rental films.

Why Is Video Output File So Large?

Hi, everyone,
I have a video screen capture demonstrating a piece of software that I work with. The video is 5:30 long at 30 FPS. It is 7.5 MB, encoded in H.264 (I transcoded it to this format myself.)
I want to cut out 1:30 of the video. So I opened iMovie, added this video to a 30 FPS project, cropped the two portions I want from the event (minus the 1:30 I don't want), and placed them together in the project with a fade-to-black transition between them. I exported the video to the same size, using the same H.264 encoder.
Now the file is 75 MB.
Can someone tell me what I have done to increase this file so much? I would love any tips to get this file back down to 7.5 MB.

there are a few other 'knobs' to play with ... :
usually, there's no need for 30fps on a screengrab - who cares when the mouse cursor 'stutters'?
for a public viewing, 15fps would reduce file size by half.
next, for screengrabs, I wouldn't suggest h254 but Animation ...
last, and most important: bitrate. in the many option&sub-options of the Export with Quicktime dialog, you're allowed to set manually the bit-rate. for plain graphical content as a sreen-grab you can experiment with ultra-low settings, <1.000kB/s or even <500kB/s ... even for a 1920x1280 video (iM had changed the res of your grab into that res).
if the grab had a smaller res, you can re-size that on export in the same dialog too.
lowering frame-rate, bit-rate and probably resolution will help you to accomplish the goal.
for the last grain of quality on low bit-rate, I would also suggest the free x264-encoder which imho performs on low rates better than the original h264.-

Lowlevel video output switch controls? Modulized, why?

Hi
Well, i use Arch on my laptop. And there is one thing, which makes me wanna jump on it. The Lowlevel video output switch controls kernel module. I need this activated in order to switch between the projector and my laptop, I have my finals soon so its important this works as it should.
Would it be possible to enable this module in later pacman-versions of the kernel? At the time beeing, I would have to recompile everything my self. Which I have yet to become successful at, something is always wrong. But I`ll summarize what I would like to do:
#Build a kernel with this option, choosing it from grub at boot-time. But still have the "pacman-version" in case i mess up somethings up.
NOTE I use luksEncrypted root, does this option do anything to the kernel? Since the installer asks if you need to boot from an encrypted volume. Just asking...
Anyway, can I just download the kernel source. Run make menuconfig, activate the Low level video output switch controls. Then -> make modules_install? And then copy the kernel-version over to boot, and use it? Or what else?
Thank you so much for helping, took me ages discovering this feature was disabled on purpose.

Not before next weekend. My best guess is next Wednesday or later.

Why is multicam source not switching cameras on video output?

When I have a multicam source sequence loaded in the source monitor and I select different cameras nothing changes on the video output (have tried both Decklink and AJA stations). It just keeps outputting camera one.
Did something break with Premiere CC 7.1.0? Anyone else running into this? Any idea how to fix?

As far as I know, there's no workaround within 7.1. If rolling back to 7.0.1 is an option, then that should get Transmit working with multicam editing. But whatever you do, DON'T roll back to 7.0.0--in case you weren't aware, it had a gnarly multicam bug.
If you revert to 7.0.1, please consult this thread: http://forums.adobe.com/message/5823746#5823746#5823746.

Premiere CS4, NO hardware video output aceleration?

All Premieres for Windows, from early ones up to CS3 were supporting hardware acceleration in "video space" for output via OVERLAY or DIRECTDRAW (VMR that is just a bit slower). That allowed to archive very low CPU utilization, very FAST video frame draw and refresh, very clean colours... And possibility to mirror on full-screen devices (e.g. TV, calibrated monitors etc.)
Today I'm testing new CS4(with updates)... And they removed this so essential feature!
WHY!? How could they stop supporting Overlay ?
Do they, in Adobe, think that everybody in industry are so crazy to move to Vista that has no 2D video acceleration?
Do they think it is very funny to catch dropped frames and frame disruptions during playback?
I have not very slow station on C2Q9650 with tons of hard drives and accelerated by nVidia that I love for good YUV overlay support, various outputs and easy colour setup...
And with CS4 I dropped on the level of 90th with buggy S3/Trident video and Pentium-Pro.. The performance so horribly degraded.
ADOBE! Come to senses, bring back 2D accelerated video output to Premiere Pro CS4 ! You are ruining whole experience!

Do you understand difference between 1) clip mixing/effect processing and 2)video overlay matrixing/up-downscaling in native accelerated YUV space?
Yes - CUDA is ideal for clip mixing and effect processing, predominately in RGB24+ spaces.
I personally use OGL accelerated FFT3D filtering via AVISYNTH. It unloads 30% of CPU time for other preprocessing code.
But this is NOT video output mixing/ fast DAC output!
It uses the same RGB GPU RAM space as conventional 2D/desktop graphics uses.
Overlay uses separate accelerated hardware block that works without double framebuffering for scaling, but scales on the fly.
Overlay works in native YUV colour space, what is much faster. And overlay multiplexes output to various display devices via hardware without penalty!
Actually, what was done is SOFTWARE rendering on GPU device. This is NOT hardware accelerated output!
Yes, you can buy a $3000 GPU and overtake $0.001 classic overlay accelerated chip block... with HUGE graphics board which needs regular maintenance!
(and still you'll get some frame phase dislocations on output device. Main DACs are not necessarily field/frame phase-locked as Overlay block)
Bye-Bye notebooks for "field operations"! Welcome oilcan for regular gpu-fan lubrication!

Satellite P300-13J - S-Video output shows no picture

Hi,
I need a little help here.
I have P300D-13J and I bought it with OS Vista HP 32-bit. I have tested S-Video output few times after time I bought my computer and it worked fine,no problems.
But,after a few months I needed S-Video output and I connected cable like any other time I did that(same cable,same TV),and it didn't worked!
I thought it was some software problem,and in that time my copy of Windows 7 HP came. I've installed Windows 7 HP 32-bit on my computer and everything is working super,but I still have the same problem with S-Video output. I need to say that with instalation of W7, I installed all newest drivers from Toshiba web page.
When I try to move screen on TV, I use FN+F5,and it has a button called TV. But if i chose TV,my FN shortcut key blocks and nothing happens.
When I go to Display Settings and connect TV on S-Video,I have second monitor (No.2) and it is called Non PnP Generic Monitor or something like that. I can not change any settings on that monitor,not even a resolution.
So,does anyone has this kind of problems or solution for this?

Hey Stevan,
I had the same issue that I couldnt see a picture on my external monitor that was connected via S-Video cable. The solution for this problem was very easy: I had to change the TV-standard from NTSC to PAL!
Of course its depending on your country where you life but you can find this option in display driver options.

Video Output ALWAYS dictates Audio Out!!??

I have a Black Magic card in my system. To save space on my working monitor, I'm viewing my movie from the output of my Black Magic card on an external monitor. However, the audio is also being sent to this monitor. I'd like to do my mix with my headphones, and not on the crappy monitor speakers, but every time I change the video output, the audio always gets sent to the monitor. I have to watch the video in a window on my monitor to be able to listen over headphones, which is a waste of space. Why can't I control this?
In my audio prefs, audio output is set to built-in output.

Weird, I have both setup, Windows 7 with Lenovo Graphic Driver and Windows Server 2008 R2 with Nvidia Driver, both have audio output.
Try to go to Device Manager to see if there's anything called Nvidia High Definition Audio, for me, I have 4 same devices. If there are unknown devices, install it manually with inf files.
Best Regards
Peter

No video output to 23" Apple from Windows XP

I just built a new computer with; Intel E6400 CPU, Asus P5W DH Deluxe motherboard and an EVGA 8800GTS video card. This setup will not give me any video output to my 23" Apple display that was working fine before. It will not post into the BIOS. I have not installed Windows yet. I hooked the computer up to a 19" Samsung LCD and it posted right into the BIOS with no problem. I talked to EVGA support and they think I may need a firmware update. Any idea where I could find out about this problem? The Apple is the second generation with the aluminum frame.

Let's be constructive:
BUT WHY doesn't it work? and how can we fix it/make it work?
my cheap 'non apple' video cable works fine initially, then a message pops up about it not being an 'offcial' cable or some such, then asks if I want to enable airplane mode (both with or without it already disabled), and disables video out completely. Contrary to the many others that have overpaid for your proprietary cables; I'm NEVER EVER EVER EVER going to pay you for your atrociously overpriced cables, because you're action of 'disabling' 3rd party cables is monopolistic in any sense, destroys any hope competition in this area, hinders innovation by third party peripheral developers, and is downright unamerican imho because it does so. You've gone to far this time apple! I've come to the conclusion, you obviously don't care about functionality, as your hardware is almost always overpriced, proprietary, good looking junk, and you keep shaking my pockets for more money with your overpriced accessories and constant barrage of itunes streamery.
Anyway, how can I use my device to do video out on this officially licensed apple dock I have? It doesn't seem to work; and I paid a lot of money for it. If there isn't a solution; maybe you should give out refunds for all the devices that now don't work? Thanks

One long repeating beep and no video output

Sometimes when switching on a system build with KT6 Delta , I get one long repeating beep and no video output. The problem usually is solved if I unplug the monitor cable from the vga card and plug it in again. Still, I am thinking why does this happen since the cable seems to be connected fine?

1 Beep: DRAM refresh failure
Explanation: The system is having a problem accessing the system memory to refresh it. Refreshing is done on all system memory to keep its contents active.
Diagnosis: This code usually means a problem either with the system memory or with the motherboard itself.
Continuous Beeping: Memory or video problem
Explanation: The system is producing constant beeping in no specific pattern, or a fast "ringing" sound.
Diagnosis: This is usually caused by a problem with the system memory, or possibly the video card. The memory is more likely--the system complains long and loud if it can't find any usable memory, as there is no way to even start the boot process when this is the case. The motherboard itself could also be the problem.

TOSHIBA Video output

We need help with a 2000 toshiba television set. We were given a 2000 toshiba televison set, as we planned to use it to set up a home security system.. When my son tried to set it up he came across a problem with the video output. On the menu it states 'Video Out Put Blocked'. Under that their is a place for a pin number. We did not have the pin number, so we called the previous owner and asked him about it. He said "I wouldn't know about that, I just brought it home and plugged it in"
Is their any way to get this video input unblocked without a pin number? Any suugestions would be appreciated

What model number is the TV?

External Video Output

Hi,
I'm having trouble sending the image from Color to an external monitor for accurate color balancing. When I go to Video Output pop up menu in the set up preferences, the only option they let me click is "Disabled". It's an HD image to a Sony HDV deck which converts it down to a SD monitor, but IO can do it in Final Cut, so I'm not sure why I can't do it in Color. Any suggestions?
Message was edited by: jesterhead

You'll need a third party i/o device to handle the conversion for you. If you have a MacPro, the Black Magic Intensity cards (at the low end) up to the AJA Kona series cards (at the upper end) will work. Mid way are the Matrox MXO series of external boxes - most of which will work with an expresscard34 capable laptop as well.

Photoshop CS4 video output

Hi, could i get a broadcast video output in Photoshop CS4.
I would to check colors on a PAL monitor, and i have only dv out
Thanks

You can get Firewire previews from PS Extended already. Please check the online help. If your Firewire ports and the device outputting the video signal to anlaog (your camera or a converter box) are not OHCI compliant, it won't work. the rest is unclear. That's exactly why people use compositing programs like After Effects with respective preview plug-ins for broadcast work or do it in their edit suite in the first place...

4.0 Video Output

Just curious to see if the 4.0 software update on the iPod Touch will allow video output on older/3rd party cables?
Currently, the 3.0 and 3.1 OS blocked that capability.

Mailbox effect between shared and quicktime video output

Here are some screenshots from a movie I'm making. You'll see the kid doing the limbo in the clip at the centre of the top image is mailboxed with black top and bottom. I've added some type to the frame (lower portion of bottom screenshot) and it looks like it'll fall outside the image, but when I export the movie as a medium shared video, it turns out fine (upper part of bottom screenshot). Make sense? I can't figure out why this is happening and where the edges of my frame are. The problem gets serious if I export to Qucktime because the mailbox effect shows while it doesn't show in the medium shared video output.
Any advice appreciated.

Hi this worked for me... After you've changed the stuff within the browser close it out completely, Open the actual QuickTime on your PC edit-preferences then you will see both player and QuickTime separately. You need to uncheck automatically start play in both preferences, in the second one it has a browser tab when you click that the default is set checked for automatically play in browser uncheck that go through each tab in both preferences and make sure autoplay is not enabled anywhere, Good luck Rhondar35

After Effects warning: Couldn't open Quicktime video output component????

Hello,
I was wondering why this warning is coming up every time I open After Effects-
(After Effects warning: Couldn't open Quicktime video output component.)
It also reappears every time I go to a different program then back into After Effects.
I am currently on a-
MacBook Pro running OS 10.5.5
2.6 GHz Intel Core 2 Duo
4 GB 667 MHz DDR2 SDRAM
After Effects CS3
Quicktime 7.5.5
GeForce 8600M GT
2 external storage drives (Western Digital, Lacie)
Matrox MX02
I just upgraded quicktime and this started appearing.
ANY IDEAS.

Sorry,
Here;s another. I have Quicktime Pro installed. I have CS3 installed. I also have AE v7 which runs a few plugins I am still thinking work in v7. CS3 runs OK but in version 7 it gives me the "Couldn't open Quicktime Video Output Component " notice. I had a client working in v7 so I tried to work in v7, it was a bad idea. I lost days of work and finally just went to CS3 to get the job done but couldn't use one anothers files between versions.
What can I do to get the AE v7 Couldn't open Quicktime video output component fixed. Make it simple if you can... I'm an artist.
Thanks
jm
