Viewing video feed from medical camera (Keeler video ophthalmoscope)

O video experts, I need your help.
I'm trying out a specialist medical camera. It's for looking in people's eyes, and it has an integrated video camera which gives a constant feed via a USB2 cable. It would suit my work very nicely - but of course it's only windoze. I could run Boot Camp, but I'd much rather deal with it in the OSX system if I could, and so I seek your expertise.
First of all - I've tried plugging it in, and nothing happens. IMovie doesn't register a camera being connected, neither does iPhoto or Image Capture.
So I figure the video stream must be some sort of non-standard codec that the mac isn't recognising. So perhaps if I could find a driver for that codec the mac could 'see' the stream? Once I can see the stream, I then need to be able to record it too (last step is that I need to be able to review the stream, and select frames to export as still images).
But I don't know what the codec is. How might I find out? If it helps, the instructions for installation on windoze starts with installing 'Lame MP3 Encoder' and 'FFMPEG Library'. Maybe I need mac versions of those? Do they exist?
Supplementary question - Do FCExpress and/or FCPro have extra codecs? Might they handle it for me? Easy would be good, even if it costs a few dollars. Are there other programs I should be experimenting with to see if they can handle this little gadget's video stream?
Thanks in advance,
Paul.

two probs:
• codecs.. the mentioned two ones (first is audio...) exists, ffmpeg is a cross platform project..
• connection/'drivers'.. a constant stream of data at the usb-port.. +so what?+ says MacOs.
for usb-devices even MacOs needs drivers, as Windows. for the usual suspects, MacOs comes along preinstalled with drivers (harddrives, some camcorders, still-cams, some speaker and mics, printers), BUT if there's some driver for THAT device for Mac-platform.. ? I mostly doubt..
Ask the manufacturer

Possible for 7970 to display a feed from IP camera?

I need to set up a security surveillance system using the 7970 to display a feed from IP cameras. Is it possible and if so, what kind of format can be displayed on the 7970 screens?

If your camera publishes its image as a URL you can just use an image object in Ciplets to point to that URL and set to loop back on itself every second for an update. It handles conversion from other formats such as JPEG and scaling.

Can hear but not view .mov files from digital camera

My daughter has a Samsung Digimax camera which takes video in MPEG-4 format (.mov). Since upgrading Quicktime, we can hear the video but not see it. The screen is black. I made sure I upgraded to the latest version of Quicktime (7.1.6). I have tried "Safe mode" as recommended in another post and I still get the audio but now the video is white. The movie info says "Apple MPEG4 Decompressor, 320 x 240". We were able to view all her videos with no problems before the QT upgrade.

Welcome to the Apple Discussions.
How big are the files? iPhoto won't import large files from your camera. As Larry says, move them to the desktop with Image Capture and import to iPhoto from there.

How to view tagged images from the camera in Lightroom?

How do I see a tagged image from the camera (tagged using the lock button, to remind me of a image I want to find quickly) once imported into Lightroom? This is possible to do in Photomechanic, as I can see all of the tagged images from the camera once opened in Photomechanic. Yet so far I have not found a way to allow me to do this in Lightroom so far. Any solutions welcome please.

There isn't a way to do it that is part of Lightroom. There is a plug-in that might help you, though. Check it out here: Locktastic
It doesn't say if its compatible with LR4, but you can try it to find out.
Plug-ins aren't usually as efficient as built-in functionality (like PM), but it might be a solution for you.

Error Message when trying to view/edit clips from Flip Cam

I am trying to edit some video from a flip cam on Final Cut Express 3.5.1 and it won't play. I've imported it both from an external HD and also the laptop itself and both times I get 2 error messages. First "General Error" then "Error: Out Of Memory"
I've already tried deleting my preferences but that didn't work.
Please help

Having owned several flip cams, I can tell you that the raw video clip coming out of the camera itself is a .avi file. If by chance someone had changed the extension of the raw video clip to mp4, or whatever that FCE (final cut express) likes, that will not change the fact that the clip is unusable without washing it through a conversion process. Im all in agreement on free.

Viewing images directly from the camera in Aperture?

Hello to all. I was at a seminar last wednesday and the photographer was saying that I could connect my D300 directly into my Mac and with Aperture I could see the images right after I took it. Is this true because I haven't been able to find anything on the aperture guide nowhere...
Thank you in advance and have a good one!

Hi,
This is called tethering -- watch the tutorial at:
http://www.apple.com/aperture/tutorials/#organizeimport-tethering
I haven't used it myself, as I only use Aperture on my Mac Pro Desktop, and I don't shoot in a studio.
Good luck, and check out all the other tutorials available on that same site.

Can I use my macbook air to view video from my camcorder

I have a Panasonic HDC S9 HD digital vide camera, which has a mini HDMI port to coonect to an external monitor to view playback directly from the camera
I have a Macbook Air 13" bought 5 months ago
I have bought a thunderbolt to HDMI cable and have used that to connect the Air to the video camera via HDMI
But I dont see how to see the playback from the camera on the air.
Any ideas?
I am hoping that I am not about to be told that the Air will only export video via the thunderbolt port and will not allow video IN to show on the Air screen... please help?
Many thanks

Thanks SP
But I need to do something more immediate than that.
One of the things my partner does is to advise her clients on their presentation skills. So she wants to video them doing a presnettation to her, and then immediatley play it back so they can both look at it whilst she critiques it.
There is no time to transfer video files and move between aplications.
If we connect the video camer via HDMI to the TV, we can play back clips on the TV directly from the camera - no need for data transfers
What I want to do is use the Air as the TV monitor for this playback so she can do this on client site in any room with her own equipment - not needing a TV
I had hoped that buying the thunderbolt to HDMI lead would enable the Air to act as the out put monitor
But I cannot see how to get that to work

I have just went to the Apple Retail Store and purchased an HDMI adapter that plugs into the bottom of my iPhone 4. When I asked the sales person if I could watch the videos and pictures from the camera roll I have taken on a T.V. he said I could.

I have tried to watch the videos and see the pictures from my iPhone's camera roll on a televison but it is not working. It is like nothing is connected to the T.V. set. I have tried with cables that attach to the bottom of the iPone. I have used an HDMI cable and a component cables on two seperate Televisions. How is it supposed to work.
I plugged the HDMI cable into the HDMI #4 jack into the T.V. and turned on the iPHone and watched the camera roll on the iPhone bu tnothing appears on the T.V. screen. What would have to be adjusted to view the pictures from the camera roll on the T.V. screen. The same thing happend when I used "Composite to iPhone" cables to a different T.V. I even tried with and iPhone 3GS, still no display on the T.V. screen.

Warranty on iPhone is not international, but valid only in country of
original sale. Since you purchased the iPhone in Australia, your warranty
is valid only in Australia. You must either personally return the iPhone
to Australia for evaluation and possible replacement or sent it to someone
in Australia to take into Apple for the evaluation. Apple will not accept
international shipments for repair nor will Apple ship out of the country
after replacement.
Sorry to be the bearer of this news, but it is the way iPhone warranty and
replacement has always worked.

I can't import image files from my camera to Photoshop Elements

My iMac recognizes my camera (a Canon Powershot S100 Digital Elph). I know this because it automatically starts iPhoto and loads the images. The problem is, I am sick and tired of iPhoto, and I want to use Photoshop Elements instead. When I connect the camera to the iMac (via a USB port), I do NOT get a camera icon signifying a new volume or drive on my desktop. So when I open Photoshop 4.0, I can't find the files to import. I could allow the computer to import automatically into the iPhoto library, then manually drag the image files into a different directory for use by PSE, but that seems way too complicated. Why should I have to do that? Please help if you can.
John

I'm using OS X 10.4.11.
Maybe I didn't explain it very well. Let me try again:
I would like to be able to connect my camera to the USB port of the iMac, turn on the camera, and then view the images from the camera memory on the screen using Bridge (the subroutine for file management in Photoshop Elements). I have not been able to do that.
Instead, my iMac immediately displays the camera images by opening iPhoto. There is no option in iPhoto for importing the images to anything other than the iPhoto library. So I have to go find them there, copy them into the directory were I want them, and then erase them from the library (which is a little tricky by itself). Then I can manage them in Elements/Bridge.
I thought when I bought Photoshop Elements that I would be able to open it and then tell it to import the images from my camera, into a directory of my choosing. That would be less error-prone and a lot less work.

I can't import and view videos from a camera.

I can't import and view videos from a camera. Even if I open the file and copy the .avi files onto the hard drive. I have tried iMovie, Quicktime, and Flip player. Flip player will open it but I only get the audio, Quicktime freezes, and iPhoto tries to automatically import only to then error saying the files are not compatible.

Hello Hese,
try the following:
1. delete preferences (com.apple.iMovie.plist) and empty the trash
2. repair disc permissions with Disc Utility and reboot your mac
3. use Diskwarrior or MacJanitor for disc clean-up
4. disconnect any other firewire devices
5. take off any non-system desktop pictures
If nothing else helps, you might want to consider resetting your Firewire port(s)

Live video feed from camera and other PC

My Mac Pro is being shipped as we speak. I'm new to this, and not up with all the lingo so please bear with me. I'm hoping you all can help me figure out what I'm trying to accomplish:
I currently VJ (Video Jockey) with certain software on a PC and send that video mix out (DVI or VGA) to a Plasma TV. I just bought a Canon A1 camera and a Mac Pro w/FCP studio. How can I mix the live video feed of the Canon with the video feed from PC (preferably in HD)?
I also want to be able to record and edit the footage from the Canon later.
I was told by the guys at the Apple store that I could do this using FCP multicam. Is that true? I read a couple posts on here that say FCP is just editing software and can't do live feed. Then what is the purpose of multicam? Please help. Thanks-
mac pro Mac OS X (10.4.8) Two 2.66GHz Dual-Core

The Apple people probably didn't understand that you wanted a live mix. FCP can't help you there.
MultiCam is an FCP feature "post-switching" multicamera recordings for that live-to-tape look. It is fairly complex, and especially with only two "cameras" you would be muchn better to start off editing them on the timeline.
As for a live switch you need a video switcher. Outside the realm of FCP, but http://bhphoptovideo.com is a great place to do research.
Then if you're really serious you can record both feeds plus optionally the live switched output for further manipulation in FCP or elsewhere.

Video uploaded to an iPad from a camera

It says under the tech specs that the iPad can import (with camera connection pack) photos and VIDEOS from your camera.
I have a Canon camera that shoots 1080P video...the iPad doesn't list 1080P video as a supported type...
1) What happens to those imported videos? How do they show up under the iPad interface?
2) Is there any way to view those videos on the iPad (without manually converting them on a mac 1st)? Can the iPad do some conversion of its own to show the videos after they are imported?

Try putting the video file in the photo sync folder, launch itunes and highlight the file in the folder. Then go to itunes, advanced pulldown menu and selecting "Create ipad or apple tv version". If the file is compatable, itunes will tell you. If not, it should start conversion.
The above is from memory so a step may be slightly different, but the idea is there.

Problem regarding the transmission of video Through TCP/IP acquired from USB camera

I want to transmit video using TCP/IP protocol acquired from USB camera. Acquisition is done well but when I place the TCP VIs in the acquisition VI then the trouble begins and I can’t even get the video in that particular VI which was acquiring video and working fine previously.
Interesting thing is that both Cam Server and Cam Client VIs was transmitting video in the very first run. After that I don’t know what happened.
I am using lab view 8.2.1.VIs are attached.
Please help me out.
Regard,
Aftab

Hi Shoaib,
Here's an example I was testing mixing IMAQdx and the Simple TCP/IP Messaging Protocol (http://zone.ni.com/devzone/cda/tut/p/id/4095) to send up a video client/server app with a USB camera that I was testing with.

Only photo's & not video's downloaded from my camera?

I downloaded photo's from my Sony camera into Adobe Photoshop Elements 12 & Adobe Premier Elements 12, but video's from my camera did not download. Why? And how do I download my video's into Adobe Photoshop 12? Need an answer and solution to this problem.

Hi,
When you open the dowloader, click on the Advanced button if not already in advance mode. Is the option to hide videos turned on?
Which Sony camera are you using?
Since you mentioned Premiere Elements, you may also like to ask the question in that dedicated forum.
