    1 - How do I use the sequence editor?

    Contributed by Michael.

    The best tutorial for the sequence editor is Bart's work in "The Official Blender 2.0 guide" this book is recomended for it has a complete listing of the 3d modeling and animation functionality(not the gaming).

    First open up the sequence editor, either change a window or open 'SCR:screen.002' on the top header that gives you an ipo, prewiew, and sequence window. A quick sequence: first you need a movie, with the curser in the sequence window 'shift a' click on 'Movie'.

    In the file window click on the movie you have made, it will appear in the sequence window as a blue strip, move it to channel 1(channel's start from the bottom with 1) and to the left. Add the same strip a second time, place it on channel 2 and off set it by half of the frames(if it's 40 frames long off set by 20 frames). With the 'a' key deselect both segments, then with the 'shift+rmb'(the same as you use in the 3D window for multipule selects) key select both segments, bottom one first. 'shift a' click on 'Add' place it on the third line. Move to frame 20 and you'll have two overlapping frames of the same movie offset by 50%.

    To render or animate, in the display buttons set the 'Do Sequence' button pick the file type, add a name, set the start frame to what ever the overlap is and the end frame to the end of the overlap and animate.

    You have enabled field rendering. This is an option that you only need when you are planning to output your animation to video. To disable this, switch to the Display Buttons (F10) and disable 'Fields'.

    3 - Reversing a sequence in the sequence editor.

    Contributed by Michael Thoenes.

    Do you want to make that sequence reverse? No problem!


    Follow these steps:(Presumes Default Blender Screen Configuration)

    1. First you need to work from a folder of rendered stills. Blender does this very well. If your already there, skip to step 2, If not, here's how:

    1a: In the display buttons, browse to the render destination folder you have already created by clicking the square in the upper left of the display buttons window. (The one left of the button that says "/render/")

    1b: Set your render output buttons to JPEG or TARGA, set the Start and End frame buttons. (Shift-Left Click the button and type the frame numbers in , or click click click) Set the size, Quality, RGB, BW , etc. Also, I prefer to have extensions on my image files... Click the extensions button (Lower left of the panel)

    1c: Click ANIM button. (Your folder will now fill with a sequence of images.)

    2. Go to Sequence Editor (Select "SCR:screen.002" by pressing the minus next to SCR:screen... at the top of your Blender window.)

    3. Put your mouse cursor over the Sequence Window (Middle window vertically), Shift A brings up "Add Sequence" menu, select "images" and browse to your folder full of images.

    4. Now for the fun part!
    In your image file list window that appears, you will have 3 ways to sort your images before inserting them. Find the "A/Z" button (That's alphabetically). If you do a Shift A in the widow to select all and hit enter, you will insert the images in rendered sequence (Forward). Find the Check Mark button to the right the "A/Z" button. Click this and your image file list will display the rendered order from most recent to oldest. (This is the reverse of what you had with A/Z). Now do a Shift A in the window and hit return: A sequence of frames in reverse order is inserted into the sequence editor:
    The third button sorts your images by file size.

    Cool Right!

    What if you have an avi to reverse? Well as best as I can tell, you will need to put it into the sequence editor and render a folder of stills to insert in reverse order by clicking that check mark button. Blender does this very quickly.

    Hope this helps someone out!

    Blend On!
