Quicktime video capture from VCR

Hey Guys….
I have this issue quicktime and I'm not sure what is going on. So basically I'm capturing video / audio from a VCR into quicktime. Sound works fine. The video is coming through, and the color is fine. but the video is distorting slightly. I know it's not the VCR because when I plug into the TV directly, the picture is fine.
I'm using one of those USB 2.0 Dongle's that capture video / audio through composite cables. Quicktime is picking it up as I see the video on the screen, it's just distorted slightly. Kinda like when you used to hit the "tracking" button on the VCR back in the day.
I'm using OSX Lion on a 2007 Macbook Pro.
Driving me nuts. The capture dongle says it works both PAL and NTSC. Any help would be appreciated.

1). To answer your questions. I am plugging the VCR into a receiver, So it comes up on the TV, and through the Receiver A/V outputs I am using the dongle. I took a picture of it. And yes I am using the dongle's Composite inputs, and then the dongle plugs into the Mac via USB. I thought it could be the receiver, but then I plugged the VCR directly into the dongle with the same results.
Currently unable to view posted images. (Not sure if this is an issue with the files or the Apple server—i.e., the link appears good but nothing loads to browser page. Was hoping the image might better identify the problem as I am now wondering if some sort of double encoding in taking place with USB device encoding data, passing it to the QT 7 app which is the re-encoding the data.
2). It appears to have a MPEG 4 decoder, but I'm not sure on that. I plugged a Nintendo Wii into it to test it, and the picture came up fine with the Wii.
Still not clear on how the USB device works. Can you provide make and model info so I can look it up on the internet?
3). Quicktime version 7.6.6 pro
Which preference setting are you using? What are the stats for the "captured" file contents.
4). The distortion is like when the "tracking" was off a little when watching VHS tapes back in the day. The image sharks a little and sometimes there are blurry lines. But you still can make out what is on the screen. I've attached a picture to show.
Unfamiliar with your use of the term "sharks" here. Are you referring to a general decline in picture quality as individual line progress across the display or the normal "comb" effect caused by the motion of objects in motion across the display between the two fields that compose a single video frame. (I.e., the distance an object moves between the capture of odd and even fields that compose the video frame.) The latter is quite common when capturing interlaced (VCR) content in an application like QT 7. (I.e., your TV and the Wii could be displaying the fields at a frame rate of 60 fps or more which better approximates the display of an older analog TV displaying interlaced fields as separate frames rather than QT 7's attempt to capture the two fields as a single interlaced frame.) If this is you problem, you could try deinterlacing or decombing the captured content but would likely degrade the quality in the process.

Unable to capture from VCR

I am trying to capture some video clips from VCR into Final Cut Pro to create a historical record for the family.
I have done this successfully in the past using moviebox dv however I recently upgraded my IMac and the new model has a firewire 800 port instead of a firewire 400 port like the last model I had. Since this upgrade I have been unable to use the moviebox dv as final cut does not even recognize it is there.
Are there any compatibility issues that anyone is aware of?
I am using a 3.06 Ghz Intel Core 2 Duo 20" IMac with osx 10.6.5
I have already posted in the wrong forum and got some suggestions,
http://discussions.apple.com/thread.jspa?threadID=2709119&tstart=0
but none which have helped yet. They suggested I try in the FCPro forum, so here I am
Does anyone have any other suggestions or feedback?

Excellent ... but sadly you can confirm that the unit is operating properly with this cable?
Unfortunately this has been the experience of some folks trying to work with DV (FW100) devices connected to FW800 host ports on their computers. I don't know the cause of the issue specifically, but one workaround that has worked for many, including myself, is to pass (daisy chain) the signal via a different device that hosts both FW400 and FW800 ports ... for me, when using a Sony J1 deck, that was achieved by using an external FW drive that I had available. I connected the drive to the computer via FW800 and the J1 deck connected to the drive via FW400. It worked.

Problem with GF4 MX460 VTP - Module Capture from VCR

I have problem with my GF4.
When i try capture from VCR, the bottom of image has a distorsion, like a cut off peace.
I don't know if the driver, software of capture (Ulead Video Studeo 6.0), the "excellent" Windows XP Professional or simply my VCR.
Somebody can help me.
Thanks

Walter,
I have the same problem. I don't think it's a software issue (unless the capture driver causes it). The bottom 7 lines of captured video seems like shifted right.
You can use VirtualDub ( http://www.virtualdub.org ) to capture, setting crop options to ignore last 7 lines.
I agree with CrazyCamel, use virtualdub and HuffYuv codec http://www.math.berkeley.edu/~benrg/huffyuv.html
This codec does lost free compression, and is *very* fast. You can capture at 320x240 writing average 2.2 MB/s (against over 5 MB/s uncompressed). It allows you to capture 640x480 or 720x480 (DVD quality) with low frame lost (maybe none, depending on your system).
I hope these links helps you.

Transmiting video captured from a webcam to another system through internet

Hi there, I developed an application catch video stream from the webcam and transmit it another system within LAN network , I would like know possibility to senting it over internet to another system?? is it possible sent this streams to more than one location simultaneously. Any idea?
Best regards

hi tony
Thank you very much for reply, I very appreciate this.for tansnsmitting video using rtp protocol we need to specify the network output for media transmission(ie Medialocator).what i mean is we need to create a medialocator specifing the destination of our broadcast. which look like a typical url rtp://address:port/content-type ,here the address is the address to which video must be tansmitted.to transmit in unicast mode this address should be the address of the intended machine.its working fine.to transmit in mulitcast mode with a subnet we can do this by replacing 255 with last field of the address part.it also working fine within subnet so that we can display video captured from one cam to multiple destination
** this is the real problem whcih i m facing now is how to make it to work in internet? to mutliple destination? whether i need to create multiple medialocator url??? anybody have any idea? plz help thanking u in advance?

1080p live video capture from camcorder to MacBook

Is there a device or adapter that will connect the 1080p from a video camcorder's HDMI out to a MacBook's thunderbolt or usb port with QuickTime receiving the camcorder's video and audio when "New Movie Recording" is selected from that application?
Or more succinctly, can I turn my 1080p camcorder into a webcam?
Camcorders have better image quality than webcams (okay, maybe not necessarily JVC, but Canon's do) and more features, such as 38x zoom. And my MacBook has a much nicer and bigger screen than that little LCD fold-out piece all camcorders have. So combining the superior video capture of the camcorder with the superior display capability of the MacBook along with the advantage of live recording directly to the MacBook's harddrive (no intermediate SD card file transfer step from device to device) would result in an enhanced video capturing experience. All that is required is some adapter that will take HDMI from the camera and translate it into something the MacBook will see as a webcam (usb or thunderbolt). So where do I find such an adapter?

What brand and model is your camcorder?
From this we can determine what format it outputs in, because you capture with the output format from your camcorder. You then, after editing, use PRE to Share your project as MPEG2.
These are the import video sources supported by PRE:
If your camcorder manual is telling you that it outputs MPEG2 (this is a standard definition format) try the 'DVD Camcorder or PC DVD Drive' format.

Video Capture from Elgato

Hi all,
I'm entering into the Video Production world and I'm evaluating to buy a tool to get old VHS tapes into my iMAC.
Reading on newspapers, webs, etc. I found the Video Capture product from Elgato.
Is someone using it ? How it works ? Can I consider it to enter in a professional manner into VHS to DVD conversion ?
I know that there is a similar product (Roxio easy VHS to DVD) but from a US MacWolrd video it seems that Elgato is better ?
Is someone able to comment on that ?
Thanks
Giancarlo

Neither of the products you mentioned is the correct product if you plan to edit the video. The Elgato Video Capture website claims: "Elgato Video Capture transfers video from a VCR and other analog video sources to your Mac in a format that is ready for iTunes®, an iPod® or iPhone™, YouTube™, and iMovie®"
None of those formats are suitable for editing. The same is true of Roxio's Easy VHS to DVD.
If you don't plan to edit the footage, then either will do. But if you do plan to edit "in a professional manner" then you'd need a DV converter like the Canopus ADVC line of products. A DV converter (or qualified DV camcorder or VTR) will convert the analog video/audio signal to a Firewire signal that can be captured on your Mac in a format that is native for most NLEs. The ADVC300 adds a TBC - further enhancing/stabilizing the analog signal.

Capturing from VCR?

I'm currently making a showreel of my work, however some of it is on VHS. Is there anyway I can link a VCR to my Mac Book Pro and capture from it on FCP? If not can my Mac link to the VCR and turn the programmes into Quick Times or similar?

You'll need an I/O device and there are loads of them available but it may be that you already have one that is ideal for capture to edit purposes ... do you have a DV camera? If so then it probably has an AV in port to which you can send the output of your VCR, you can then pipe the DV output into your MBP via firewire and capture into FCP as DV.
In the loads of them category there is Blackmagic's aptly named Video Recorder: http://www.blackmagic-design.com/products/videorecorder/
its pretty cool but nowhere near as cool as Matrox's MXO2 Mini which is standout awesome:

How to fix audio of a video captured from DV output of camcorder using Adobe Premiere Elements 8?

Hello,
I purchased Adobe Premiere Elements 8 about one week ago. I installed it and everything seem to work well in my first project. I am new at editing videos but I was succesful in testing it by loading an existing video file in avi format from my computer and then doing some very basic editing (I splitted 2 scenes and added a title).
After my first succesful project (described above) I started a brand new project. Here, I want to capture a one hour video from the dv output of a video camera. So I connected the camera to the PC and then started adobe elements 8. Before starting the capture I only checked the boxes that said "capture video" and "capture audio" (the other 2 boxes that said download to timeline and autoanalyze were left unchecked). After that I started the capture process.
After the video capture was completed, a small window opened at the bottom saying that a PEAK FILE was being generated. After the peak file generation finished, I looked at the captured video. The video looked perfect. However the audio of the video was too fast. By this, I mean that the voices of the people in the movie were like they were speaking at more than twice the normal speed. Or to explain it in a different way, they sounded like the chipmunks.
So now I come to the question of this thread I started. Is there a way that I can fix the audio part of the video I captured? I will appreciate any help on this. Below I listed a few additional details in case this is needed.
Thanks,
ronel_8
PS. Here are some more details about my system:
1) Operating System: Windows XP
2) I am capturing the video on an external drive with 40 GB of available space. The external drive is connected to a PC via a USB connection.
3) Computer CPU: 2.4 GHZ
4) Computer RAM: 1.25 GB
5) Video tape is about one hour long.

Hello Bill and Steve,
Your responses are very helpful. Although I was not able to fix the problem yet I do seem to think from what you both say that my system may be too slow to capture the one hour video. In any case I will copy below more details about the system as you requested:
1) Results from running Gspot:
The audio section of the Gspot window was blank. That is, no information was there. The File and Container sections say:
File Size: 12.6 GB
Note: 7.63 GB unneeded bytes at the end of the file
DV Type1 AVI
2) I did run the Gspot on another good avi file (captured to the PC with same camcorder) and says:
Codec PCM Audio
32kHz 1024 kb/s tot (2 chnls).
I suppose these are the audio settings from the camera.
3) Yes, I am capturing video from a miniDV camcorder (JVC GR-D70U).
4) I did not defragment the external drive prior to capturing the video with the audi problem. So I will give that I try and see if it solves the problem.
5) The external drive I am using is formatted to NTFS.
6) The computer is a Dell Dimension 2400, CPU: 2.4 GHZ, RAM: 1.25 GB
7) HDD Size=74GB and 11 GB of free space. But I am downloading video to external drive that has 60 GB free space.
One last piece of information that may be useful. If I open the AVI file (that I captured with Adobe Premiere Elements) with Windows Media Player, the audi sounds good. However if I open it with Adobe it has the problem I mentioned in my previous e-mail.
I'll aprreciate any further hints.
Thanks again,
ronel_8

Location of video captured from within iMovie?

When capturing video directly from iMovie using the built in iSight in my macbook Pro, where are the video files saved on the mac?
Thanks.

I knew about the project file, though I was not sure if the actual video media was embedded within it.
This project does not have any imports, it was used to capture new video.

Finally.... Video captured from applet in Vista!!

Hello!
Hurray!! finally I can see myself smiling and waving back in browser in Vista.
I mentioned in another thread just a day earlier that I will post a new topic if I succeed in capturing from applets in Vista, so thats what I am doing.... This thread is all about how achieved it.
I have seen many posts mentioning problems in capturing from applets in vista. I was also one of the sufferer. And most people including me blamed that on restricted sandbox of Vista. But surprisingly it was all about classpath.
I think I mentioned in some earlier thread that the 'Java console' shows the classpath to be *"{JREHOME}/classes"* instead of the classpath specified in CLASSPATH environment variable. You can check that by pressing 's' which *'dumps system and deployment properties'* in the Java Console. You can check the classpath by noting the value of *"java.class.path"* field which for my case was"C:\\PROGRA~1\\Java\\jre6\\classes". This turned out to be the main problem. The applet was not accessing any classes from the real CLASSPATH instead it was considering the classpath to be jrehome/classes. So, now I had enough hint what to do next. I simply created a folder 'classes' in {JREHOME} and copied the jmf registry files to that folder. By registry files I mean *'jmf.properties'* and *'jmf.properties.orig'* files in *'{JMF Install}/lib'* folder (actually i don't which among them has got some thing to do with the registry but I copied them both). So, after doing this, all my capture applets, whether signed or unsigned started running. Earlier they all were throwing *"java.lang.RuntimeException: No permission to capture from applets"* exception even after I have allowed capture from applets in JMF registry. That was perhaps not taking affect because of classpath issues. So, thats the story.... if someone faces the same problem he can use this workaround or you can say hack ;-)
Some questions which can be asked from me would be:
1- Did you set your CLASSPATH environment variable correctly?
ans: Yes, infact all my jmf applications were running correctly, the problem was only with the applets.
2- What classpath other systems (e.g. XP) mention in the Java console ?
ans: surprisingly, the same classpath that Vista mentions i.e. {JREHOME}/classes. I tested on XP-SP3, but it supposedly had access to the real CLASSPATH also.
3- Is this problem really Vista specific?
ans: Can't say... but it can be. It maybe the case that Vista does not allow access to real CLASSPATH, but this problem can easily be my system specific, it would be called a general vista problem if this happens on all Vista systems, I need volunteers for this test. captfoss, can you please test this on your system? :)
4- Is this problem JMF specific?
ans: Chances are low. I am going to test this by making my own test library and adding it to classpath and then try to access it via applet. If this fails then this problem is not JMF specific.
Drawbacks of this work around:
1- This can be a pain for ordinary users , copying registry files from JMF/lib to JRE/classes.
2- Whatever you change in JMF registry would not be effective to the applets. As the old registry files are to be replaced with new registry files every time JMF registry is changed for changes to take effect in applets.
The real big question:
How can we force Vista to look in the real CLASSPATH? this is the real question, if this can be done just by changing some settings then all this workaround is useless :) I am looking forward to the answer of this question.....
captfoss, I would highly appreciate your comments.
Thanks for reading this rather long post.... :)
Thanks!

A couple of comments here...the answer is, in fact, no, you didn't set your classpath correctly. One, you're probably using a JAR file to run your applet from (I'm not an applet programmer but I do believe that a JAR is required) which do not use the environment's classpath, they use their manifest classpath. No, the applet was not jared.
Second, I believe that the browser itself specifies its own classpath, which you cannot modify. I believe this would be considered a security feature...Both IE7 and firefox3 fail.
"You have little control over the CLASSPATH used by a browser for an Applet"
[http://mindprod.com/jgloss/classpath.html]
Ok this maybe the reason, I will go through the link....
2- What classpath other systems (e.g. XP) mention in the Java console ?
ans: surprisingly, the same classpath that Vista mentions i.e. {JREHOME}/classes. I tested on XP-SP3, but it supposedly had access to the real CLASSPATH also. There isn't a "real" CLASSPATH, there is just the classpath stored as an environmental variable. It's no more or less real than the one in the browser.Thats what I thought.... but I think {JREHOME}/classes is the default class path used by the jre whether we set any CLASSPATH variable or not it would be there, something of that sort.....
Lots of possibilities, but my best guess is that Vista doesn't let code running in the browser read environmental variables.Yes, I fully agree with this. I think I should file a bug report.
4- Is this problem JMF specific?
ans: Chances are low. I am going to test this by making my own test library and adding it to classpath and then try to access it via applet. If this fails then this problem is not JMF specific. Definately not. It would apply to any code that wants to access something on the classpath. You are right... as I said I would test it, I tested by making a small library, added it to classpath, made an application and an applet. As expected, the aplication worked while the applet failed.
Any application with a custom classpath would be affected.I don't understand what you mean here, do you mean 'Class-path' header in jar manifest?
I like the "installation requirement" part. I'd suggest looking into that. Alternately, there may be something in the security settings to allow access to environmental variables.I will try to look into both.
I just tried this statement in applet:
System.out.println( System.getProperty( "java.class.path" ) );It threw this exception:
Exception: java.security.AccessControlException: access denied (java.util.PropertyPermission java.class.path read)
I don't know what conclusion should I draw from this... this does mean applet has no right to know what the classpath is.... but this doesn't mean even jre plugin responsible for running applet does not know what the classpath is :)
Finally, I want to say that due to some problems I could not post earlier, and I may not post for few more days. But I appreciate your comments and would appreciate more of them.
Thanks!

IPad Mini with iMovie ap. Hooked up iPad to my Windows via USB in an attempt, through iTunes, to copy some QuickTime video files from my PC to my iPad. As I followed the instructions, it seemed I can only copy from the iPad to my PC and not vice versa.

Using iTunes on my PC, I wish to transfer some video files from PC to iPad mini. Can this be accomplished?

Hello there, FlatusMaximas.
Here is a great Knowledge Base article that should show you how to do just that:

No audio when capturing from vcr using canopus100

When I log and capture, the video is there, and the audio tracks "show up", however, the audio cannot be heard during capture (previewed), nor is it heard when I export the movie using QuickTime conversion.
I exported the file as a QT movie and played it back in QT, and of course, no audio.
Which switch have I not thrown here?
Thanks
JD

OK, I suppose it would help to know the details to provide a proper analysis of the situation.
1) Canopus 100 is connected to vcr through the s-video input, and the audio is going in through the standard mini-jack interface.
2) FCP Capture Settings are:
Device Control: Non-Controllable Device
Capture/Input: DV NTSC 48 KHz Copy
Scratch Disk Free Space = 852.3 GB
3) The audio tracks "show up" when I do a capture...meaning, there are 2 tracks placed in the timeline. I can view some audio activity in the Waveform Monitor, but I do not actually hear any audio.
On that note, audio plays fine when capturing video from my Sony PD150.
Also, when using the same set up with the Canopus using iMovie, the audio previews, captures, and plays back just fine.
Thanks again. Any additional info needed just let me know. I really appreciate it!

Isight only choice for BTV, Quicktime Video Capture

Until I installed an iSight camera, I could capture video from TV via USB and Quicktime, Interview, or BTV.
With iSight connected, Quicktime's "video source" choice is "iSight" or "Automatic".
In BTV and Interview, the only option for "video source" available is "iSight". The other video source options are grayed-out.
How do I get the video input options back?

Thanks for the new info, yattaman
I do not see a question in your latest post, but it seems to me that your TV capture device or its software is probably conflicting with iSight or your other applications.
The software that you use to drive your iSight always "takes over video input" while it is in use, so that may be your problem. As explained in this Apple kBase article, iSight can be used by one application at a time.
If you are using only one app at a time but still have the problem, be sure all your software, including the TV capture software and QuickTime are up-to-date. If your problem persists, the only suggestion I can offer is that you disconnect your TV capture device and uninstall any software that was installed with it. Carefully follow the instructions for uninstalling in its documentation. If the problem goes away when the TV capture device is not installed and returns when you install it again, that device, or its software, is the source of your problem. If the problem remains, the only workaround I know is to uninstall the conflicting device / software while you need to use the other applications that experience the problem you describe.
If you do not get the help you need here, you may be able to find additional help from the "Support" section of the web site for your TV capture device. Some of them even have a dedicated forum for users of their product.

Correct preset for video captured from VHS tape

I have bought a cable which connects to my PC USB slot and has red, white and yellow component connections to connect to my (old) VCR or Video-8 format camera. It comes with software called ArcSoft ShowBiz that allows me to capture the footage. I have used it for both VHS tapes and Video-8 tapes. The only options I have when capturing are the filename and a choice of MPEG1 and MPEG2, with MPEG1 being the default.
I have successfully captured footage (in MPEG1 format) and now I want to edit it in PE10. The trouble is I do not know what preset to use. The VHS tapes were in PAL format. If I open a project as DV PAL and add the footage to the timeline it has a red line above it, which I assume means I will lose resolution when I render. The quality is already not great and I don't want to make it worse.
Any advice would be appreciated.

Most likely that footage will not work well or look good in Premiere Elements. The capture device you're using is a low-end digitizer and likely came with some software for editing (ArcSoft Shopbiz). It's designed to work pretty exclusively with that software.
MPEG1 is a very low quality format.
You can try using the project settings for Hard Disk Camcorder/Standard Defintion for that footage -- but I make no guarantees about the quality.
The best device for capturing analog video is a DV bridge, like the Canopus AVDC, as we discuss in this FAQ.
