- Open Blender.
- Set your green cursor to the 0+00 frame.
- Go to Add-->Movie.Add→Movie.
- You only need to worry about your set frames-per-second (in Blender) being wrong if the video and audio clips show up as different lengths.
- If you have multiple clips:
- Set the green cursor to the end of the first clip, then do "Add → Movie".
- The new clip and its audio should be automatically selected.
- Press "g" (Grab) and then "y" (restrict movement to the y axis) and drag it up to a higher sequence.
- Note that you do not need to click and hold to drag the selected clip. Just move the mouse up without clicking.
- Set the X and Y dimensions to 640x480. YouTube will adjust the video to look right with a wider screen.
- Set the number of frames to 500 and do test runs to make sure everything looks and sounds right.
- Determine the total number of frames through trial-and-error.

- Container: AVI
- Codec: H.264
- Output quality: Perceptually lossless
- Encoding speed: Medium speed
