Downloaded video can't be captured. Maybe imported if it uses the proper codec, which is doubtful with downloaded material.
I'm not trying to capture anything. All of my footage is playing back fine on the timeline with no color lines above it (no rendering needed). Just trying to get Premiere to send signal through firewire into the box so I can view it on an analog monitor as I scrub/playback the timeline. (Like I did with all the older versions of Premiere.)
Click on Start -> Control Panel -> System -> Device Manager (up on top left), or just click the Start button and search for "device manager."
Swivel down the entry for "IEEE 1394 Bus host controllers, and right-click on the item that is revealed (will depend on your computer/card manufacturer). Select "Update Driver Software."
Click the "Browse my computer for driver software," and then the "Let me pick from a list" button.
In the list of drivers, select the one that has "(Legacy)" at the end; click Next, and then Close all the dialogs.
Try output now.
"Legacy" drivers made sense, but still didn't work. My very old Sony DCR-PC1 gets signal just fine from the timeline. I've tested the cable and DVMC-DA1 box (DV output from a camera). Everything is in working order. Don't know why Premiere just refuses to acknowledge it.
