JVC GY-HD100 is unable to capture to final cut pro. It shows "no communication" in the log and capture window. But It will capture useing IMovie with no problem. This creates an extra step in my workflow. Please Help!

Hi,
Yes, service manual of JVC GY-HD100 can be downloaded from HERE for small fee.
Thanks.

Push during 2, 3 seconds the "status" button on the side of the camera.

IS THE BATTERY FULLY CHARGED?

Are you using HDV, make sure you set the signal to DV on the camera. Does it have a signal out option to switch from video to dv / firewire? Have you checked to see if it is supported? Also just keep trying, turn camera on and off, restart the computer with firewire connected then without. I had this problem with a deck and it randomly started working after my 5th try.

lcd flexible cable is common problem in this model . try to move up down rotate if you see any picture change the flex cable

It is a very small fuse (about the size of a grain of rice) that is directly soldered to your circuit board. It is not a user replaceable part. You'll have to send it back to JVC to replace. In the future, what you need to do is power off when changing the battery.

you have to get to th camera admin menu

Are you shooting 24p? Make sure you're using the correct capture presets. DV NTSC 48k 24Pa (presuming you're shooting 24p advanced)
if this doesn't help, close final cut and delete your com.apple.finalcutpro.plist file from library>preferences. This should solve additional cadence problems.

Many HDV cameras and decks are able to play and record DV as well as the higher-resolution HDV format. Additionally, many of these HDV devices will attempt to automatically change their settings to match the format of the tape that it's playing. Here are some tips for using these types of devices with Final Cut Pro / Final Cut Express.
Tip: Make explicit settings on your HDV device. Instead of using an "Auto" setting, make your own settings on your HDV device to keep the communication going between it and Final Cut Pro / Final Cut Express. This also helps Final Cut Pro / Final Cut Express keep things running smoothly with HDV devices that handle both DV-NTSC and DV-PAL.
For example, say you're using an HDV deck to capture footage from a tape that was recorded as DV-NTSC. Before capturing in Final Cut Pro / Final Cut Express, make sure that you set the deck to DV mode specifically—don't rely on Auto mode. With some devices, you may need to disconnect it from FireWire to change the mode.
For a common capture workflow, this sequence of steps can provide the best results:

1. Quit Final Cut Pro / Final Cut Express if it's open.
2. Insert your tape into your HDV deck or camcorder.
3. Use the device's menus to set it to match the format that's recorded on the tape.
4. Connect your HDV device to your computer with a FireWire cable.
5. Open Final Cut Pro / Final Cut Express.
6. Choose an Easy Setup for DV or HDV (whichever matches the format recorded on your tape).
7. Proceed to Log and Capture.

Tip: Quit Final Cut Pro / Final Cut Express before changing modes. It's generally a good idea to quit Final Cut Pro / Final Cut Express before you change the mode on your device from DV to HDV, or from HDV to DV, and then re-open the application again.
Tip: Use an Easy Setup to play back non-default HDV format footage on your HDV device. You can use Final Cut Pro / Final Cut Express to make your HDV device play back footage in its non-default HDV format. For example, maybe you have a 1080i60 HDV device and want to play back footage that was recorded as 1080i50. Or perhaps you have a 1808i50 HDV device and you want to play back footage that was recorded as 1080i60. To do this, follow these steps:

1. Connect your camera to your computer.
2. In Final Cut Pro / Final Cut Express, choose an HDV preset Easy Setup that matches the format of the tape's footage (you don't need to restart Final Cut Pro / Final Cut Express).
3. Your device's LCD display should automatically display a switch to 60 or 50, indicating the type of media that's being played.

Playing back non-default DV format footage on your HDV device You can also use your HDV device to play back footage in its non-default DV format too. For example, maybe you have a 1080i60 HDV device and want to play back footage that was recorded as DV-PAL. Or maybe you have a 1080i50 HDV device and want to play back footage that was recorded as DV-NTSC. If so, follow these steps:

1. Make sure that your device is in DV/DVCAM mode.
2. Put your device into Play/Pause mode, then open the Log and Capture window in Final Cut Pro / Final Cut Express.
3. Make sure that your device's LCD (or other readout screen) displays the same format as your tape or Final Cut Pro / Final Cut Express will misinterpret what type of device you have.

Tip: Avoid recording both HDV and DV formats on the same tape. Use separate tapes whenever you want to record in a different format. If you need to record over existing footage in a different format (for example, you have a tape with DV-PAL on it, but you want to record over it with HDV 1080i50), it's a good idea to black and code the tape, or completely record over the old footage with contiguous recording in the new format. If the tape contains even a second of, say, DV in the middle of an HDV tape (or vice versa), it could cause unexpected results later when you try to capture video from that tape.
