Capturing media on a laptop with only one firewire input
So, this question may or may not belong here: I have a MacBook Pro with its single Firewire port. I have an external firewire drive for my scratch disk. But how do I capture media from my tape-based Canon HV40 onto the external disk with only the one firewire port? Is there such a thing as a firewire Y-adapter (i.e. two into one) or is that even possible? I'm thinking I may have to capture one tape onto the laptop's drive, then disconnect the camera, connect the external drive, drag the files there, and finally, after all is done, let Final Cut know that the scratch disk has been changed and the media is not on the laptop drive any longer but on the external firewire drive. Suggestions welcome, please.
I realize that the slower device on a daisychain will mean that the fastest speed is limited by the speed of the slowest device
My understanding is the speed of the bus will be restricted if you have the SLOWER of the two devices connected directly to the computer. If it is: FW400>FW800>Computer, each device should connect at their normal speed.
In any case, count yourself among the lucky as Canon cams often will not work when connected on the same firewire bus with other devices.

Capturing Video on New iMac with only 1 FireWire Port
Using one of the new Apple iMacs, what is the best way to capture digital video footage (Mini DV) into Final Cut using an external drive as your scratch disk? The iMac offers only one FireWire 800 port. Is it advisable to connect the camcorder to the FireWire port and use a USB 2.0 to connect the external drive? Or can you connect the drive via FireWire 800 and connect the output of the camcorder to one of the other Fireiwre ports on the drive? In this instance I am using a Lacie Rugged Hard Disk that has one FireWire 800, one FireWire 400, and one USB 2.0 port.
They often do not play well with other firewire devices on the same bus. And since all the firewire ports on a Mac are on the same bus, it can lead to incompatibilities during capture. On some computers they work fine, on others they collide.
Try it and see if it works for you. If it does, be happy. If it doesn't, you'll have to do the external drive/camera shuffle.
It goes like this:
• turn off the computer and all connected devices,
• disconnect the external drive
• connect the camera using a FW800 to FW400 cable
• turn on the camera
• turn on the computer
• launch FCP, set the capture scratch folder to the system drive then capture
• shut down the computer and the camera
• disconnect the camera and connect the external drive
• turn on the drive
• turn on the computer
• launch finder and move the captured files from the system drive to the external
• launch FCP and reset the capture scratch folder to the external drive
• open your project and reconnect the media.
Or, use a different (non-Canon) capture device.
Or, get a computer that has multiple internal drives or has expansion capabilites so you can add a firewire card to create a second independent firewire bus for the camera.
Good luck,

In FCP X How do I capture tape-based media (hdv clips)- which I want to import-to my external hard drive? There is only one firewire 800 port on the back of my I mac. The FCPX manual says to import tape footage directly into final cut, which works, but then I lose my external hard drive Do I have to import it into an event, then copy it over to an external hard drive? On Larry Jordan's tutorial, he has 3 external hard drives that show up on his monitor WHILE he imports his tape based media. How is that done? I can only get either the camera to appear OR my external hard drive. thanks for your help.
Thanks for your response, but that doesn't solve the problem. Yes, the LaCie hard drive has 2 firewire ports-
I have always done what you suggest (works fine in FCP7), but in FCPX when I do that the camcorder icon
does not appear. It only shows up when I DIRECTLY import the footage via firewire. ???? -
Importing m2t into iMovie with only one conversion
Ok, so m2t files have been beaten to death in these forums, but I'm still puzzled. Here's my situation. I have a Canon HV20 and only replay the tape once to avoid wear and save time (really?). So I capture to m2ts. Fine. Now I'd like to be able to use these in iMovie with only one conversion. I can convert the stream to a framed (QT) format like AIC. But I'd like to do this just once. Meaning, when I convert clip.m2t to clip.mov I'd like to drag this to iMovie and have iMovie just "copy" an not import/convert. Can I convert to a format where I can just drag to the media folder in the given iMovie project?
For those watching. My toolchain is
1. rewind the tape
2. capture with HDVsplit (win), DVHScap (mac), or whatever
3. split/clip the m2t files with HDVsplit (win) or MPEGstremclip (mac/win), or HDVxDV (mac) and leave as m2t
4. convert the m2t clips I want in my movie to QT+AIC
5. import these QT+AIC .mov clips into iMovie
6. edit
I'd like to optimize 4 and 5. (And by the way, someone should port HDVsplit to mac.)
Thanks,

MPEG Streamclip allows you to export as QuickTime with Apple Intermediate Codec (also QT Player can do this but I prefer MPEG Streamclip for these tasks). I think you should set the resolution to 1440x1080 because that's what iMovie uses internally for 1080i.
I did a quick test and iMovie seems to accept such AIC-encoded .mov files directly to its Media folder. But run some tests through your complete workflow before trusting this will work!
Ok this was helpful. If I take 1440x1080 QT/AIC output from MPEGstreamclip, I can efficiently copy the file in the project. Works like a charm and looks great in iMovie. (I can also now take the 1920x1080 QT/AIC output from streamclip and do the same; not sure what change there. I did a test on a 1:24 length mpeg-2 stream. The 1440x1080 with and without deinterlacing were 700MB and 600MB respectively, while the 1920x1080 is at 800MB. So it makes sense to do 1440x1080 since iMovie handles it fine.)
In summary (hope this helps someone), here's what I do:
0a. Macbook with iMovie HD
0b. LaCie macos formated external drive drive (hfs+)
0c. Canon HV20 filmed at 1080i (not sure what do with the 24p cinemode)
1. use DVHScap (mac) to capture the stream from the HV20. This gives file.m2t, for example. This can be viewed with VLC, for example. (on windows use HDVsplit to capture). Copy the m2t file to the external drive.
2. now use MPEGstreamclip to disect the m2t file. use the 'i' and 'o' to mark inputs and outputs and then "save as". Save this as file_clip.ts for example. The .ts is the same as an .m2t file, so save it as either.
3. now you should have 1 or more file_clip.ts depending on how many times you do step 1 and 2.
4. use MPEGstreamclip in batch mode to take the file_clip.ts or m2t files and "export to Quicktime". Select Apple Intermediate Codec as the type compression type. Yank the quality up to 100%. Select 1400x1080 (4:3) as the frame size and click "deinterlace video" (my opinion on the deinterlacing). Save the movie on the external drive as file_clip.mov.
5. now start a new iMovie HD project and save the project to the external drive. Quit iMovie. open-apple-click on the myproject.iMovieProject to "show package contents". After this you can move your file_clip.mov files to the media directory under this package. A move is best since copy does an actual copy. Move just moves a pointer.
6. start up iMovie and view the trash can when prompted ("Some stray files were found in the project...."). Now drag the trash files to the clips area in iMovie.
7. now edit.
This is a nice approach for a couple of reasons. The .m2t files are great storage formats. The conversion from mpeg-2 stream (m2t) to a framed format like QT+AIC (mov) is done +only once+. And the quality is maintained. Also, I can do this all to an external harddrive, which is nice since I'm limited on my macbook.
I don't have HD gear. Currently I archive SD DV to tape and to big harddisks. In the future I would like to continue to archive HD content in its native compressed (non-AIC) form. Obviously this works via DVHScap, right?
Yes. The m2t files are a great archival format. The 1:25 long clip above was only 275MB while the framed formats were 3 times that. The stream saves differences so it's a lot more efficient (but you don't have frames for editing). VLC is also quick as quick for viewing these. DVHScap never drops any packets (mpeg-2) when capture (for me at least). HDVsplit is also great, but only for windows. HDVxDX also worked like a charm.
Well anyway, thanks for the chatter.

How can I synch my ipod & iphone music (purchased from itunes on my old laptop) to my new laptop? I keep getting the same message on my itunes on my new laptop: " The ipod/Iphone is synched with another itunes library. An ipod/iphone can be synched with only one itunes library at a time. What would you like to do - Erase and Synch or Transfer Purchases?" What do I do?
A couple of other items:
1) I am guessing Apple does not keep a history of all my music purchases? As I did not have my entire library backed-up anywhere, and relying on the music I have on my ipod and my iphone as my only source of itunes music....I have lost over 500 songs!!!
2) I used to have an Apple account under another account name, and since have switched to a new account name. Is there anyway to find the history of purchases from my old Apple account name and transfer these over to my new account name and onto my new laptop?
I hope someone can help, I am having a very difficult time trying to obtain answers. AngieThe iphone/ipod is NOT a storage/backup device. Not maintaining a backup copy is a big mistake.
You can transfer itunes purchases from your iphone/ipod to your computer:

How to connect many devices with only one FW800 port in iMac?
Hi,
I am upgrading to a new Intel iMac from a 2004 vintage Dual2.0GHz PowerMac. I currently have 8x d2 Quadra drives chained by FW800, and 2x Iomega drives connected vis FW400 hub which also connects HD cams.
My questions is that with only one FW800 port in iMac, I think my devices connectivity is the following?
(1) Get a FW 800 hub (I can only find 2 port ones at the Apple store and BestBuy)
(2) Connect the d2 Quadras to one port of the FW800 hub
(3) Get a FW 800 to FW 400 cable
(4) Connect my 6 port FW400 hub to the 2nd port of the FW800 hub
Thanks for reviewing this solution, and I would also appreciate other suggestions or hear about your experiences if you have a similar set-up.
WillIn addition to your listed considerations, you should consider the following.
Many storage needs do not required FireWire 800 speed. For example, USB 2.0 works fine for your Time Machine backup drive. If you are just storing user data such as your iPhoto or iTunes media files, USB 2.0 is more than fast enough. So, as much as possible, if any of those external drives have USB 2.0 connections and the data storage does not need FireWire 800 speed, offload as much as possible to USB 2.0. I used to be a +FireWire snob+, but since getting an Intel iMac, I find that USB 2.0 works quite well for most data storage purposes.
There are new hard drives that are power efficient and as large as 2TB. Consolidate your data storage needs onto a smaller number of very large drives, partitioned as needed. This will make your setup more reliable (smaller number drives), and save reduce power consumption. If any of your current externals are SATA, you can probably replace the existing drive with an extra large one.
So, I think you setup should be, extra large FireWire 800 drive connected to the FireWire 800 port directly. Using a 9-pin to 6-pin cable, connect the FireWire 400 hub. Connect any non-storage FireWire 400 devices there. Do some data transfer testing to make sure having the 400 hub there on the chain does not cause the 800 connection to slow down.
Connect other drives as needed using USB 2.0, existing or new. Retire the smaller of your external drives. -
Counting (interneal timebase)events with only one counter
Hello,
i am using a PXI-6115 card. This card is external clocked with 8 MHz. But I want to measure only about every second. So I divided the external clock with the internal counter 0. This works fine.
Now my problem. Now I want to know the external clock rate. Is it possible to build a pulse period measurement with only one counter??
I thinking of counting internal timebase- pulses with counter 1 and to start and stop the counter 1 by the output of counter 0.
Is this possible and how??
Thanks for help, RuedigerYes, there's a way to measure pulse periods with a single counter. The trick is to perform a buffered period measurement and sum the periods. The size of the buffer will determine the quantization/roundoff error.
The source of this error is that you have no control over the initial phase relationship of your external clock and your internal timebase. There's a nominal ratio between the two frequencies, and you'd start by expecting ratio * (buffer size) total cycles counted.
However, your actual count must be an integer, so you'll get either the next-highest or next-lowest integer, but you can't predict or control which one.
Example: If you collect 1 period at 8 MHz using the internal 20 MHz timebase, you'll capture either 2 or 3 e
dges from your timebase, implying a measured frequency of either 10 MHz or 6.6667 MHz.
If you collect 1001 periods, you'll capture a total of 2502 or 2503 timebase edges, implying a measured frequency of either 8.0016 MHz or 7.9984 MHz.
Notes:
1. In many cases, you can set up for buffered event counting, using the internal 20 MHz clock as a source and your external 8 MHz as a gate.
The advantage is that the buffered values already represent cumulative time so you don't need to sum them.
A disadvantage would be that the internal 24-bit counter value will roll-over in less than 1 second at 20 MHz. I typically capture periods and then sum in software because I can convert to floating point between capture and sum if necessary to produce both high-resolution and long duration measurements.
2. You should typically ignore the very first value in the buffer and work only with the others. If you want to capture 1001 legitimate periods, size the buffer for at least 1002

How can I play different videos with only one MediaPlayer?
I want to play two videos with only one MediaPlayer:
private static MediaPlayerBuilder mpB;
private static Media mLogo;
private static Media mSaludo;
private static MediaPlayer mpLogo;
private static MediaView mvLogo;
private static Group gLogo;
public void start(final Stage stage) {
mLogo = MediaBuilder.create().source(myGetResource(VIDEOLOGO_PATH)).build();
mSaludo = MediaBuilder.create().source(myGetResource(VIDEOSALUDO_PATH)).build();
mpB = MediaPlayerBuilder.create();
mpLogo = mpB.media(mLogo).build();
mvLogo = MediaViewBuilder.create().mediaPlayer(mpLogo).build();
gLogo.getChildren().add(mvLogo);
sActual = new Scene(gPozos, WIDTH, HEIGHT, Color.BLACK);
stage.setScene(sActual);
stage.show();When I want to play mLogo:
sActual.setRoot(gLogo);
mpLogo.play();Then, when I want to play mSaludo I do this:
mpLogo = mpB.media(mSaludo).build();
sActual.setRoot(gLogo);
mpLogo.play();or this:
mpB.media(mSaludo).applyTo(mpLogo);
sActual.setRoot(gLogo);
mpLogo.play();or this:
mpB.media(mSaludo);
sActual.setRoot(gLogo);
mpLogo.play();But is impossible to change the Media. It doesn't work. Sometimes I play mLogo video and sometimes (depends on the code) the video mLogo doesn't start and I see an image of the first keyframe and nothing else. I have no exceptions, no errors, nothing.
I want to play mLogo and then mSaludo. How can I do this?
Thanks
NoeliaOk, I understand, if I have 100 videos I have to build 100 MediaPlayers but only one MediaView.
Here I post my code with only two videos, I included all the asynchronous errors.

An iPhone can be synced with only one iTunes library at a time
I recently bought a MacBook Pro, and I figured it would be pretty simple to move my iPhone to sync with iTunes on the Mac from iTunes on my pc, afterall it is the same program and both are designed for the iPhone.
I have been successful in getting the Contacts and Calendar to sync, but the Music, Applications, Video and a few other things give me this message when I check the sync box:
"The iPhone is synced with another iTunes library. Do you want to erase the iPhone and sync with this iTunes library? An iPhone can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPhone with the contents of this iTunes library."
Obviously, I don't want to erase everything. Actually, I don't care about Music, Videos, Podcasts or Ringtones as I don't have any, but I do care about Photos and Applications. Actually Photos I can reload too, but I don't want to loose the apps I have purchased with the iTunes App Store.
I even tried going back to the PC and unchecking the Sync boxes on it, hoping this might disassociate it from the phone, but now even on that PC I get the same message.
How do I disconnect phone from the old iTunes and be able to sync it to the new iTunes? This should be simple right?I made an appointment with a Mac Genius and I will say that while it was better than getting to talk to India on a poor quality phone call it was just about as helpful. Sure she was cute and friendly, but I left without my issue resolved and was surprised that I didn't even get a followup from anyone asking about my experience (hence my venting here)
Anyway, I found a solution for my issue here: http://tinyfish.net/2008/07/18/how-to-sync-iphone-with-multiple-computers/
This is a real solution to the issue, and has the benefit that I can do this to as many machines as I need and sync at any of them instead of just one. Hopefully, Apple doesn't delete my response since it truly is the answer to the problem and others might be looking for the same solution. -

Same as you would if you bought a pc; copy everything from your old computer to your new one. Then you can just sync everything from the new computer, as you did with the old one.
