USB Video Input

I'm not sure if this should go into the iMovie section or just general OS X section but, I'm going to put it here.
I'm working on a project for my job where I need to transfer some instructional videos that are VHS to DVD. So we (the people I work with) bought an LG GSA-5169D "One-Touch Video to Disc" DVD burner that has RCA in (to connect the VCR to the Burner) and then USB 2.0 out (to connect to the computer). It comes with Windows software, that once installed allows you to... do what the product is advertised to do, import a playing VCR to a video file and then burn that to a DVD. The point is, it allows video capture from a USB Video Input device.
Well, I have a Mac Pro (that also has Vista Ultimate installed on it) which makes me not only the best candidate for ANY video processing work but, everyone I work with has pretty old machines and none of them can transfer the video at high enough quality (the Windows software locks out certain levels of transfer if it reads a CPU that is too weak).
But, we thought that what might be possible is to use iMovie to capture video from this device. And it would be possible if we could get iMovie, or rather OS X, to recognize the connect USB device as a USB Video Input device. Now I know that since 10.4.3, OS X has a UVC class driver so, shouldn't it be able to see the input? Am I just grasping at straws?
(By the way, for those of you thinking I should just install the software on my Vista partition and do it that way, the software just locks up when I attempt to install it on Vista. Braindead, BS LG software.)
Basically, to lay it out simply, my goal is to somehow get some sort of adequate video capturing software to recognize and receive and USB Video Input.
I'd appreciate ANY kind of help or suggestions.

The only hope I've ever found for doing it straight through, with no passthrough camera, is using VideoGlide (http://www.echofx.com/videoglide.html) but I can't quite figure it out. When I go into Video sources, USB Video Input is grayed out even though that's what it's supposed to do. It even lists the drive that I have on the page as a supported device! I don't know.
Yeah, I figured there were plenty of people with my predicament and you gave me a solid reply so I'm just going to mark this question as resolved. Thank you.

USB Video Capture

Hi
Does anyone know of any USB video input/capture devices compatible with a Mac G4?
I've had a look on the net, and the only one I can find is the Interview XLR8 but that only captures 1/4 screen. Anyone know of anything better?
Some discussions on similar topics suggest doing it through a video camera, however I do not currently have one of these, and would like something that stands alone.
PowerBook G4, 15" 1.5GHz Mac OS X (10.4.5)

Actually the Pinnacle Pro USB is not Mac compatible. It requires Windows.
However, Elgato recently released the EyeTV 250 which is a fairly reasonably priced solution. I am thinking about picking up one myself.

How can I connect my iPad to a TV that only has an s-video input available but also has a usb port on the satellite box available.

I would like to connect my iPad to my older TV but the only inputs available are the s-video input port on the TV itself and there is also a USB input port on the satellite box that feeds the TV. I could also split all the RCA jacks to accomodate another input here. Thanks in advance for any and all help with this problem of mine..............RR.

There is no s-video cable available for any iPad.
The USB port on the cable box is for maintenance use only.
There are RCA cables available:

Video input via USB?

I know I can't input to iMovie via USB.
But I have a Pinnacle analog to USB video converter/adapter that I'd like to use to import video from VHS tapes to mac.
The Mac doesn't seem to recognize the signal.
Is there a way to manually select the source?
Any suggestions on an encoder, I also own Final Cut Express , 2but never installed it.
Thanks,

Yes, pinnacle software is definately not mac compatible, some of their hardware devices seem to indicate mac compatibility via firewire however.
What you are viewing are their packages that bundle the capture device and variations of their editing software, which is the basis for windoze MovieMaker.
I am looking for anyone who might have knowledge on how to utilize the video signal as the pinnacle capture device delivers it via usb.

Capturing video input via a usb connection

i have a usb converter from interview 2.0. one end is the usb input and the other end has two different input options . . . one is an rca video input and the other is an s video input.
is there a way to get this to work with imovie or something else on my pwerbook?

iMovie is a video edit app meant to work with firewire connected miniDV camcorders
.. firewire isn't just a plug and a cable, it is also some protocol standard... that's why you don't need any "drivers" to make iM work with any fw connected camcorder...
some link to the manufacturer of your "converter" would be useful, I can not google any specs with your infos...
but I'm afraid, that is a "PC only" product...
so:
a) no, doesn't work with iM
b) needs some additional apps to get any input into a Mac... usb uses a very "slow" and instable connection, so my guess is, it uses some kind of compression, which isn't natively supported by iM (as mpeg) => needs conversion.... not useful.

S-Video Input

Hey guys!
I would like to replace my current Intel Pentium 4 PC and cannot decide if I should get an iMac or build a PC. Anyways, I am not going to ask that here since I know what the outcome is going to be.
What I would like to know is if the iMac supports S-Video input via an adapter / splitter like most PC video cards with VIVO do. The reason why I need this is that I have a DVB-C receiver which I would like to use with my computer because currently, I don't have a TV. I know that I could buy something like the Elgato eyeTV if I needed S-Video, but that would be too expensive right now and also a waste of money because I only need the S-Video input - no need for a TV tuner or the ability to record shows.
Seb

There is no video input on an iMac. The only way to get video into an iMac is through Firewire or USB.

Package for DVC80 USB Video Interface

Gents;
Some info sources say that a linux app can be provided which will permit the DVC80 to respond to NTSC video camera input.
The DVC80 operates well in windows, permitting capture in Irfanview and a program called Dazzle.
The following data describes a possible application which may be compatible with arch. The interface in video apps, especially from USB, can be daunting. Audio is also provided on NTSC basis for camera input via the DVC80 input connectors(stereo).
The data below describes how it might be built in linux:

Readme for kernel 2.6.x Linux device driver for the Zoran/Nogatech USBVision Video Grabber
Author: Joerg Heckenbach <[email protected]>
Homepage: http://www.emuit.com/webcam.html (Dwaine Garden)
INTRODUCTION:
This is a driver for the USB video bridge USBVision from Zoran/Nogatech, a USB-only cable used in many "webcam" devices.
It supports streaming and capture of color or monochrome video via the Video4Linux
API. Most V4L apps are compatible with it, but a few video-conferencing programs
do not work yet.
If you need more information, please visit the Zoran/Nogatech homepage at the above URL.
usbvision-0.9.6 is the first prerelease of the 1.0 driver. I did many changes in the code and I hope I
didn't break working features on different devices. The decompression is completed. Just from time to
time there are some black or white error pixels in the image on slower machines. Maybe it is a timing problem
in the isoc interrupt routine. We stay a third of the time in interrupt and so it is likely, that the parser
is called twice. Let me cleanup the routine for performance, move the parser to user-context and add a lock.
For 2.6x kernels we can use the saa7111 from the kernel tree, so the make will not compile the saa7111-new
for these kernels. The bt819-new.c is not coded to 2.6. kernel yet.
I have tested the driver with kernel 2.6.1, 2.6.2 to 2.6.7 with devices "Hauppauge WinTV USB FM 1" and
"Pixelview PlayTV USB Pro FM" on a 600MHz PII system.
WHAT YOU NEED:
- If you want to help with the development, get the chip's specification docs at
http://www.emuit.com/webcam.html
- A Video4Linux compatible frame grabber program (I recommend xawtv or Kwintv)
xawtv is available at: http://www.in-berlin.de/User/kraxel/xawtv.html
- Radio Application to take advantage of the radio tuner. (some of the devices)
GQradio is available at: http://gqmpeg.sourceforge.net/radio.html
HOW TO INSTALL THE DEVICE DRIVER:
First way (The easy one)
It works with most modern standard installations.
a) In the usbvision directory do
make; make install; modprobe usbvision
b) Start your video application.
c) Enjoy.
If c) doesn't work, something went wrong ;-)
Second way (Not as easy as the first one)
You need this, if either usb-, i2c-, tuner- or v4l-support is missing in your kernel.
a) cp the following files into the directory /usr/src/linux/drivers/usb/media
usbvision.c
usbvision.h
saa7113.c
i2c-algo-usb.c
i2c-algo-usb.h
usbvision_ioctl.h
c) In the makefile of the dir /usr/src/linux/drivers/usb, look for the line "obj-$(CONFIG_USB_IBMCAM) +=media/",
insert an additional line then added the line for the usbvision driver
obj-$(CONFIG_USB_USBVISION) += media/
e) Add the line to the makefile in /usr/src/linux/driver/usb/media/
obj-$(CONFIG_USB_USBVISION) += usbvision.o saa7113.o i2c-algo-usb.o
f) Edit file /usr/src/linux/drivers/usb/media/Kconfig
Paste the following lines below after the entry for the IBMCAM.
---------------------------- Begin Paste ------------------------------
config USB_USBVISION
tristate "USB Zoran/Nogatech USBVision Video Grabber Support"

---help---
   Say Y here if you want to connect a Nogatech NT100x, or a Zoran
   ZR36504/ZR36505 chipset based video/tv/radio grabber, to your
   computer's USB port.
   For more information, read <file:Documentation/usb/usbvision.txt>.
   This driver needs the following support: Please enable (Y or M in config)
      Video For Linux API
I2C API.
BT484 Device Support
DPC7146 demonstration board Device Support
   This code is also available as a module ( = code which can be
   inserted in and removed from the running kernel whenever you want).
   The module will be called usbvision.o. If you want to compile it as a
   module, say M here and read <file:Documentation/modules.txt>. This
   video grabber has several configuration options which can be specified
   when you load the module. Read <file:Documentation/usb/usbvision.txt> to
   learn more.
---------------------------- End of Paste -----------------------------
h) If it is not already there (it usually is), create the video device:
mknod /dev/video c 81 0
i) Sometimes /dev/video is a symlink to /dev/video0
You will have to set permissions on this device to allow you to read/write
from it:
chmod 666 /dev/video
chmod 666 /dev/video0 (if necessary)
When configuring the kernel choose Zoran/Nogatech USBVISION video support as
module. You are going to need also to select i2c and v4l, and if your
device have tuner you need to compile also BT848 support or other modules
that compile the tuner.o module.
a) Do a make modules, make modules_install.
b) If the USB Support and the Video4Linux was compiled as modules.
   modprobe usbcore.o
modprobe usb-uhci.o <OR> modprobe ohci-hcd.o
   modprobe videodev.o
b) Install the modules:
      modprobe usbvision- For a great radio application, try GQradio.
The usbvision module will also load the i2c-algo-usb, i2c-core, saa7111, saa7113.

FINAL NOTE:
If your device isn't known, add it to usbvision_device_data and usbvision_table in usbvision.h.
You can speed up tuner detection, when adding "options tuner addr=your_addr" to /etc/modules.conf.
If your device isn't known, edit line (modprobe usbvision CustomDevice="0x0573 0x4D31 0 7113 3 PAL 1 1 1 5 -1 -1 -1 -1 -1")
in 'usbvision.rc' file then 'usbvision.rc start'
also edit "etc/rc.d/init.d/usbvision" if you use it
Please tell me your experience ([email protected]), or contact ([email protected]).
=============================================================
As described it is a PAL device. There are options for TV included.
I am interested in single frame capture and video stream capture via the camera input connectors(NTSC-stereo audio). My camera is a PIXERA and has video NTSC output.
The following is reference to the USBVISION tar.gz which seems to require ZORAN in the kernel. It used to be called ZORAN/NOGATECH.
It would seem necessary to enable ZORAN in the latest kernel in order to implement the device. Other requirements are likely as well.
Perhaps a pkg could be built but certainly seems a big challenge!
My DVC80 is recognized in USB.
Hopefully, it can be done in arch!
EDIT:The tar.gz reference below:
file:///root/Desktop/usbvision-0.9.8.2.tar.gz

I use this one with Windows 7:http://www.chronos.com.tw/Product/E/2/USB%20Movie%20Editor/USB%20Movie%20Editor.htm
It worked bad with out of box Windows 7.
But after all updates it works very well and stable.
A nice thing is that it has little USB extender cable included. So it is less harmful for laptop usb port.

No video input for external devices on iMac 24" display???

I got a 24" iMac a few days ago and love this thing. (Was in PC **** for last 30 years...) But one thing I am disappointed in is that there appears to be no video input to display video or to video capture. Is the only way to display video from an outside source by using a USB video capture device? For example, if I have a cable box or game console I want to display on the monitor, how can I do that? Seems silly to need to use a capture device to simply display video. Please let me know if there is simple way to do this. Thanks!

I don't see how using a camcorder would help especially although it would be technically possible to use it as a bridge between other devices I can't see how it would be worth your while.
Obviously not speaking from experience since almost all if not all DV cameras have passthrough, and feed video into a mac via firewire from the analog audio and video input port on the DV camera. They have been used for ages as decks (and are many times cheaper than DV decks) and as converters vs. buying a Canopus box etc., which are basically the same thing.
The EYE TV 250 does the same thing with a USB connection and its own software but for the myriad of DV cam owners the passthrough is a fine idea.

View HD Video Input on iMac Screen

I would like to view the high-definition output of my cable company's hi-def cable box (via firewire, hdmi, dvi, usb, or composite connections) on my iMac's scree. Is there any such device that will do this? I have a high-def tv stick that does work with over-the-air ATSC broadcasts, but its only other input is standard analog cable at standard definition.
Would something like this ADS Pyro video capture device work for this?
http://www.adstech.com/products/API-558-EFS/intro/API-558_intro.asp?pid=API-558- EFS
It appears to have hi-def inputs and output capability, but I'm not totally sure.
Thanks!

The iMacs support Video Input since iMac mid 2009 i have Play Station 3 connected on my new 27" iMac mid 2011. Im using the Belkin's HDMI to MiniDisplay Port Adaptor (It is only posibble to use the "DisplayTargetMode" from iMac-OtherMac, you have just to press cmd+f2) For all the other devices you will need an Adaptor cuz' otherwise u won't be able to input at all, or you will not be able to use High Resolution hope this helped ppl, gl.

Video Input Tecra S2

How can I put on a Video input on my Tecra S2. I want to play Xbox 360 in HD on my Notebook. Is that possible? Maybe there is a dockingstation or something like that.
Hope someone can help me
greetz

Hi
I agree with Jaba. Your unit has no video input port like some newer units and you will not be able to use notebook display for something like that.
I believe that the only solution can be some external device that can transfer the picture into notebook using USB port or even PCMCIA card. For example I have connected my VHS recorder to my older Portege using Pinacle studio xxx. Sorry but I can not remember the right name of this hardware part.
Bye

Video Input on set top

How can I use the video input on the HD set tops? How about the USB?
Solved!
Go to Solution.

The short anwer is you cannot use either video inputs or the USB port on the STB or a DVR..
The only part of the USB port that is functional is the DC power. The inputs (and USB port) other than the Coax Cable are not supported by firmware, and as a result, are completely non-functional. As of IMG 1.9 the e-SATA port on the 7216 and 7232 DVR's is functional, and can support an external HDD for more capacity. Prior to IMG 1.9, the e-SATA port was non-functional.

Usb video

I am looking at a couple of devices for Powerpoint presentations and have come to the realization that I will not be able to do composite video out from my macbook pro with the mini-display port.
So I found a couple of pico/led projectors that have usb input. Will my macbook Pro work with these? Does the MB Pro output video through it's usb port.
http://www.hmdxaudio.com/review/product/list/id/1426/
thanks for the help

There are USB video adapters that work with MBPs, so yes, it can output video via USB. I don't know whether or not those adapters require proprietary drivers or prefpanes; if they do, your projector will too. Here's an example of such an adapter:
http://eshop.macsales.com/item/NewerTech/VIDU2DVIA/
You may want to call OWC and ask whether that adapter needs a driver or just works without one.
You could check with the maker of the projector, though I suspect they don't want to be bothered with any questions: the link to the projector's instruction manual on the page you linked goes nowhere. I wonder if it even comes with instructions.

Using iPhone 4 as video input for iMovie

Hey everyone,
I've been wondering if it is possible to set up an iPhone 4 as the video input source for iMovie 11 so I can see on the Mac's screen what I'm pointing to iPhone at; to make sure it is in focus, etc. I know it's possible to set up other video cameras but I don't seem to be able to get the iPhone to work this way.
Is it possible, or am I on to a loser here?

Not possible. iMovie does not import from iPhone in real time. It will most likely be faster than real time based on how fast your Mac is.
If you have a USB web cam or a FireWire tape DV cam, you may be able to do this. Thes importn in real time.

Iphone capable of video input?? Ccd and camera installs???

Please apple and consumers... Does iphone have the capabilities of any video input?
If not directly, what about a usb adaptor and an app?? It would be a perfect tool for me to set up cameras and other ideas i have... Please teach me??? Apple, i suggest this highly for future products if not seen now...

You are not addressing Apple here. If you want to let them know what you are thinking, you can provide feedback here [www.apple.com/feedback/iphone.html]

L2321 versus L2230 LCD Monitor - video input and preset modes differences

If someone can help clarify this so that I can understand which is the better monitor and the reason for it, I would be very appreciative, or perhaps they are much the same and it is the difference in the size which makes them appear to have a difference.
Thanks!

I am trying to decide between the ThinkVision L2321 and L2230 LCD monitors, and although the obvious difference is the size (ie. 23 in versus 21.5 in), the only thing I have a question about is the difference between their Preset Modes Text and the Video Inputs description which I found on the Lenovo Website when I do a comparison of the two.
L2321 - 23 in.
