https://www.youtube.com/watch?v=cCsPmzrwXG0 AS you can see it is limited to the black line. Im sure theres a way to make it view the WHOLE of your video, but i dont know how and i cant find a tutorial to do it. thanks, Bye
I'd be willing to bet that you need to set the frame range. The length of your video is pretty close to 250 frames, which is the default.
Check out #2.
The length of the video is also controlled by frame RATE. Make sure this is set to the same frame rate as the original video.
Check out "Frame Rate" set to 24fps below.
At the bottom left of the 3D window, click on the view icon and choose "Timeline". At it's low edge can be found the frame range settings. it usually starts at 1, the next to the right being it's max. It's probably set at the default 250 frames.
Change this to whatever the loaded video is in length. If you're not sure, put in 1,000 and see what happens. Re-select the 3D window (Bottom left icon) and choose "3D Window again), then ALT-A to make it play.
I struck this problem myself when first using Blender. Hope this helps
PS: You can drag the 3D window down from it's top right (triangular hatch pattern) so you have 2 windows. Set the bottom one to the Timeline view. Leave the cursor in that and press the "HOME" key to adjust it to cover the current frame range.
