Video capturing and motion detection

to anyone:
is it possible to capture video and detect motion using a web cam in a web based application?how is it done?
if not possible, what solutions can you suggest so that i can put it on a web based application?
tnx for the help..

the same as the other post so let's stay on the other...

Mega simple video capture and edit program. Cross platform.

Looking for a mega simple video capture and edit program. Am overseeing a bunch of small groups where we want each person in the group's story told. Some groups will have Macs, some PCs, some iPads, iphones, etc. So needs to be cross platform.
Really, the simpler, the better. Like targeting 5 year olds

Is there any software anyone recommends - Sorenson?
I am capturing regular dv from minidv.

Going to do a video capture and it is blurry

I got my new mac book on Thursday of last week.. I did two videos on my new Imovie 11 and they were great. Today I go to create another video (capture) and it is blurry, like it has some special effect on it. I check and there are no effects that I can tell.. Can you help?

dang it! haha. right in front of my face. I thought there was a way to do it with quicktime but couldn't find it. I guess I didn't look hard enough. and the Help doesn't tell you this at all, although maybe I didn't use the right words for Help.
thanx.

WVC210 and Motion Detection/NAS Device

I was using the CSWVM Software (latest) with my WVC210 and leaving my PC on all the time. I had the camera recording 24x7 to a folder on my PC but only when it deteced motion. Thsi was working great.
I invested in a NAS device (QNAP TS-239 Pro II) and want to have all motion deteced recorded directly to the NAS so I can leave my PC off. Since without the PC on, I did all configuration thru the web interface. All I seem to lose access to is the scheduling. I can get the camera to record ALL activity to the NAS with no problems. While trying to get the motion detection working, it seems I can't get it to record anything to the NAS. I am fairly certain I have everything configured per the Admin guide but still nothing.
Under Applications/Motion Detection I have Enable Motion Detection in all positions checked and set the area as full screen and threshold in the middle. I do not get anything to record to the NAS even with the Enable SMB/CIFS Alert checkbox checked and NAS login, etc configured. The ONLY way I can get anythign recorded to the NAS is with the option under Applictions\SMB/CIFS cgecked (Enable SMB/CIFS Recording). With this set it records EVERYTHING.
In the sensitivity section, I rarely see the red bar appear even when action is in front of the camera. I am not sure why. I know this should work, any ideas why it is not?
Also, I noticed if I record to the NAS at 320x240 I get an AVI I can play in Win7 WMP with no problem. Using 640x480, the AVI is unplayable in WMP and I have to use VLC Player. Is the codec different depedning on the resolution?
Thanks!

Thanks for the info. I do have the interval set to 0 and have tried the slider on both ends. I have the slider set all the way to the left (on -) which provides the most sensitivity. I still don't not get all motion captured for some reason. For this reason, I am recording full time to the NAS.
I agree the web interface is lacking and I am not sure why it doesn't work the same as the software. If it did, I could only record on motion and capture what I need instead of just alerts or everything. With the software it was nice to capture motion and just get activity (and all of it from stop to start) recorded.
My NAS surveillence software does not handle the WVC210 but I have gotten it to record full time but with that option I get no audio so that is no good either. Motion from the NAS software didn't work all that great because camera is not supported with the NAS surveillence software.
Arrgh. I don't want to leave my PC on. If only the web interface worked like the software. The playback of 640x480 vs 320x240 in the web interface stinks too. It has to use different codecs.

Video capture and system properties

Hello,
Two questions on mmapi and video capture:
1. On a Samsung SGH-A707 phone, I get a return of 'false' when running
System.getProperty("supports.video.capture"), indicating that it won't
allow video capture thru mmapi. However, when running
System.getProperty("video.encodings"), it returns
'encodings=video/H263'. Isn't this a contradiction? If it doesn't
support capture, why would it show an encoding? Does the return of false
absolutely mean that the phone doesn't support video capture?
What am I missing?
2. On an LG CU500, I get a return of 'true' when running
System.getProperty("supports.video.capture"), indicating that it will
allow video capture thru mmapi. However, running
System.getProperty("video.encodings"), it returns 'encodings=jpeg'. How
is jpeg a video encoding? Isn't this only for snapshots? Do they mean
motion-jpeg?
These are both new-ish phones, and both support video capture natively
(outside of java).
Last question: How widespread is support for video capture thru j2me?

Hello there,
And welcome to Apple Discussions!
I have recently bought a fifth generation ipod, and have used the video capture feature.
First of all, this should have been posted in the +5th generation iPod Nano+ forum instead of the *5th generation iPod Video* one. Here is the link to this forum for future references.

When I sync the ipod to itunes on my mac, will I lose this video capture?
No. Videos you take on your iPod have to manually be removed from the iPod either through the iPod itself or by opening up the necessary folders and files on your iPod through Windows Explorer.
And if so, how can I sync the ipod to a new itunes library without losing the video recording I did on the ipod?
Why would you need to worry about this? Was your nano previously synced with another iTunes library? If not, all you should have to do is hook it up to the new iTunes library and you should be good to go. For instructions on how to remove videos from your iPod, see pages 55-56 of your iPod's manual, which can be found below.

Problem with Video Capture, and question towards solution

Yesterday I worked on a commercial for which we captured 9 clips (roughly 10 seconds or shorter in length). The clips all had text/titles superimposed on them by an outside machine and looked good in the monitors when they were exported and captured into FCP (ie: none of the text was chopped off).
I edited the commercial and then was exporting it out, only to discover that the text on the bottom of the clips was getting chopped off.
My first question is this: is there some setting in the capture process that could have done this? something that might have gotten tweaked accidently, or corrupted in some manner? Didn't have this problem with footage captured the previous day. And since it looked good before it was put into FCP, thinking it had to be a problem with FCP.
Also, in trying to tweak the footage in FCP, I came across a 'there must be an easier way to do it' question. Is there a way to alter parameters on multiple clips (such as raising them, like I had to)? I tried selecting all and double clicking, hoping that the changes I made would affect them all, but it only affected the one I directly clicked. I'm sure there's something simple (and obvious) that I'm overlooking...
thanks!

For how and why this could have happened, would you mind sharing your capture and sequence settings?
As far as applying parameters to multiple clips, I think you can make use of the Paste Attributes function in FCP...
Alter one of your problematic clips
Select that clip in the Timeline, then press Command-C (or control-click and choose Copy from the contextual menu)
Select the remainder of your problematic clips
With your clips selected press Option-V (or control-click on one of them and select Paste Attributes from the contextual menu) to bring up the Paste Attributes dialog
Select Basic Motion - under the Video options, on your left-hand side - then click OK
(Basic Motion because, if I understand your solution correctly, you altered the Center property - either in the Motion tab of the Viewer or manually in the Canvas - of your clips. You nudged them all up a bit, right? If you did, then that would fall under the Basic Motion attribute.)
All your selected clips should be nudged up appropriately.
But, again, I'm making a bit of leap since I'm not entirely sure what caused your issue in the first place.

Video capture and than transmit it

After I made live video capture from (and play it with Man Media Player) I want to transmit this stram (using RTP) to other computer. How could I do this? Thank you.

I used VideoTransmit.java sample from Sun (JMF solutions...). My problem is: I want see what I transmit. For this I need a Player for my Data Source. If I used a player for my Data Source I cann't used it for transmit. It is already allocated. I could clone my data source and use one for player and the other one for transmit. It works thus. I tried it. But the stream locks from time to time. I need other solution. If I used JMStudio->File->Transmit... the stream is played and transmited very good.

Audio video capture and combination Nintendo64

Hi
I was hoping that someone could help me with mixing a video and audio signal for live playback.
I have a N64 with its video component hooked up to my TV capture card, and the audio connected to the line in on my sound card.
the computer i'm using has a fresh install of arch, with xfce. I currently just have alsa installed, as far a sound stuff goes and everything is working fine.
right now i can see the video from my nintendo with "QT V4L2 test utility" which is all good. I can't make this video full screen or any bigger. I do know i can use cheese to view the video in full screen, but it does not handle any audio.
so, what program can i use? or how can i play captured audio live?? is there a program (something like cheese or not) that can handle the capture and playback of both audio and video????? the latter is prefered
any input would be good, some ideas could help me along
thanks guys

ok cool VLC seems like a good option, i can capture the video just fine becasue i know the video device name is /dev/video0 but i don't know what the audio device name is..
i have been looking online for a way to find this out. but i have not yet found a way to tell me what the audio device name is for my sound card. (i have the audio input connected to a PCI sound card)
i just found this which helped a bit
http://forum.videolan.org/viewtopic.php?f=32&t=81166
it turns out that when i have a look the sound card i want to use is alsa://plughw:0,0
so i go -> show more options -> play another media synchrously and enter alsa://plughw:0,0. all goes well

Digital video capture and the K8T Neo

I was wondering if anyone has had any luck capturing digital video with a machine based on this motherboard. I've tried using various programs, including Adobe Premiere Pro, Scenalyzer, DVIO, and Movie Maker. Regardless of what I use, I end up with enough dropped frames to make the video very choppy in places, especially if I try to capture type-2 (video for Windows) DV, as Premiere Pro requires for editing.
Here's my setup:
MSI K8T Neo
AMD Athlon-64 3400+
2 X 512 MB KingMax PC-3200 RAM
Hercules RADEON 9800 Pro graphics
1 X Maxtor 60 GB Ultra ATA hard drive (model 5T060H6)
2 X Maxtor 250 GB SATA hard drives (model 7Y250M0)
Plextor 708-A DVD+/-RW
I've tried the following configurations of hard drives with no success:
500 GB RAID0 array on Via controller, 60 GB drive on tertiary IDE, running from one drive and capturing to the other
250 GB drive on Via controller, 250 GB drive on Promise controller, 60 GB drive on secondary IDE, tried capturing to each
I've run some tests of disk write speeds, and they seem more than adequate for video capture (approximately 50 MB/s write for the SATA drives, 25 MB/s for the Ultra ATA drive).
I've read that there were issues with PCI bus throughput with slightly older Via chipsets, and that there have generally been issues with Via ATA controllers.
So, has anyone successfully used this motherboard to capture digital video? What did you have to do to prevent frame drop?
Thanks in advance for any advice...

Video capture and JavaFX

I've run throgh few threads in this forums and the sites, but I could not find when (and if) video capture will be supported by JavaFX (audio is not a major problem, as it is supported in JRE). It is possible to know something about it ?
Where any roadmaps for future releases (in terms of contents / release dates) are published ?
Thanks.

JavaFX does not support flash streaming.
JavaFX does support http live streaming: http://en.wikipedia.org/wiki/HTTP_Live_Streaming
JavaFX does not support audio/video capture (there are other java/native libraries that do that).
See:
Video camera capture/streaming: example implementation "Thread: Video camera capture/streaming: example implementation"
http://javafx-jira.kenai.com/browse/RT-3458 "Camera and Microphone" (go vote for this jira to get some capture technology built into JavaFX).

Blu-Ray video capture and burning with G4 Power Book ??

Good afternoon.
Has anybody figured out this route with a G4?
If so, please explain in nauseating details! Hardware, software, etc.......
Thanks for your time!

Thanks for your reply.
It's also my understanding that OS X doesn't natively offer Blu-Ray support, and that an external Blu-Ray player/burner is required (see OWC) along with capture and burning software (Toast 10).
I'm wondering if anyone has tried and succeeded.

Web-based video capture and detection using web cam

to anyone:
is it possible to capture video and detect motion using a web cam in a web based application?how is it done?

Ironman wrote:
I'm sure it could be achieved by capturing individual frames, say one every second or so, and then doing a checksum on the image bytes and compare it with the previous frames checksum - if they were different then the frames are different and therefore motion can be assumed. If you don't want to check the entire image you can choose a tile, say in the centre of the picture, and checksum this. I use this technique to detect frozen images if CCTV cameras are causing problems. This other thread may also help :

Wow, now that is good idea. I guess you don't need external hardware to check for movement. Brilliant!

Bringing FCP video captures into Motion

Im doing a project where I have captured video in FCP from a mini DV camcorder. I captured the video using the DV NTSC default setting.
These clips need to come into Motion in the highest quality possible.
What is the best protocol for bringing those clips into Motion?
Do I export the footage out of FCP first and then bring that file into Motion?
Do I drive to where the Capture Scratch is and import the clip from there?
Do I need to turn on HiQuality Video setting in Quicktime Pro on the clips Im bringing in before I use them in Motion?
Thanks.

Take your elements (clips you want to use), stack them up in the video layers select them and ctrl-click on the stack and select Send to Motion project. Select the imbed Motion Content flag and the the Launch Motion flag. Don't worry about High Quality settings, don't worry about capture scratch - just let that be behind the scenes/under the hood stuff.
