One area of Blender that is often over looked, or people are downright unaware of, is its video editing capabilities. Hidden behind the 3D functionality we all know and love, under a layer of yes… sometimes confusing UI, lives a remarkably capable NLE non-linear editor.
In this tutorial I am going to look at some of the simples and most common features Blender offers when it comes to video editing. We are going to look at a couple extremely common tasks, and how you would accomplish them using Blender. Without further ado, let's jump right in. The first step is to fire up Blender. I personally am using Blender 2. NLE functionality was also available in 2.
The NLA editor sequence area is where we add all of our video elements, such as video, audio and images. In the top right it is in preview mode they are both the same window types , showing a preview of the video we are creating. The timeline view is where your timeline controls are, as well as controls for setting keys, video duration etc. The graph editor is for fine tune control using f curves and will not be used much in this tutorial.
As is pretty common, we want to have a static "Title Screen" of sorts. In our case it is just a simple png image we are going to display for 5 seconds. We are recording at 30FPS, so that means frames. First we need to add an image. This is because I am working in p output. Use whatever you wish. Locate the file you want as a title screen. In the left hand side, locate start frame and set it to 0, and end frame and set it to Finally click Add Image Strip.
The image will now appear on Channel 1 of the NLA sequence, like such:. The left hand side, the vertical axis represents the different channels composing your video. In the crudest sense you can think of these like layers in a graphics program with obvious exceptions, such as the fact they can overlap, and contain sound.
Then in this case, the purple object represents your image. Different components have different colours as we will see. The length of this bar represents the duration that the image is visible in the timeline. You can navigate this window using many familiar Blender hotkeys. The most important for now is G rab to move the active item around. The middle mouse button pans around, while the scroll wheel zooms in and out. While the ".
With only a single channel, these two features aren't really all that useful yet. So, that's the sequence view, but you should also notice at the top right corner, the other NLA window is showing an active preview, like so:.
Just like before, select the movie file you want to add. Set the start frame to , and set channel as 2. As you can see, the video starts right where the image ends.
Depending on the video file you uploaded, you may have gotten two channels like I have… what is going on here? Well, the blue strip represents the video portion of the video file we added, while the green portion represents the audio track.
In this case we want to keep the audio. If you didn't, getting rid of it is as simple are right clicking it, then hitting X to delete. There is one potential problem though, the audio isn't synced by default. Let's correct that right away.
Right click your video in the NLA Sequence window and take a look in the properties to the right hit N if the properties Window isn't visible. Locate the Length:. This added another frames to our total length, for a total of frames. We need to update our video length. In the timeline, locate End, click it in the middle and update to Now you can go ahead and preview your handy work up until this point.
Just to the right of the end frame you just specified, are a set of VCR like controls:. The field to the left currently valued represents the current frame, while the buttons are for controlling playback. The preview window at the top right should update as you got from frame to frame.
Now we have a title screen and a movie with audio, synced and playing back. Let's look at one of the next most common tasks…. Adding a watermark or signature to a video is one of the most common tasks you need to perform when editing a video, and fortunately it is remarkably simple. In fact, it works exactly the same as when we added the title screen. All we are doing is adding a mostly transparent image over top of our scene for the entire duration of the film.
Create a p image in whatever image editor you prefer, just make sure everywhere except your watermark is transparent. I used this image:. Nothing really exciting. On the left hand side we want it to start at Frame 0, go until Frame and be on channel 4, like so:. If you look in your preview window, it probably just went all black except the watermark, like so:. In the NLA Editor sequence, make sure the watermark image is selected by right clicking it, then in the properties window hit N if not visible , select the Blend drop down and choose Alpha Over, like so:.
Then voila, in your preview Window everything is back to normal, just now with a watermark in the bottom right corner! This process thus far assumed that your video was perfect and continuous, something that is rarely true. So now we look at…. Just like back in the days of physical film, cutting up and reordering video is a remarkably common task.
Fortunately it is also quite easy. We are now going to split our image in half, and put an interruption in the between the splice. First thing you want to do is select the point where you want to make the cut. You can do this using the vcr style controls, by left clicking anywhere in the timeline, left clicking anywhere on the VLA Editor sequence, or directly entering a frame in the current frame box.
The green line indicates the currently selected frame:. Once you have your video where you want to perform the cut, hold down SHIFT and right click both the video and audio portions of the video strip the blue and emerald bars. With both selected, hit 'K' to perform a hard cut. At this point, you have essentially "cut" the film and audio tracks into two separate entities.
Let's put a pause of 60 frames 2 seconds in between our cut. SHIFT select the audio and video strip on the right, press G to move them and move them 60 frames to the right, like so:. Now let's insert an image to be displayed during the gap. Using the same method we did before, add an image. In my case I want it to start at frame , end at frame and be added on channel 4, like such:.
Now if you play the video you will have a 2 second pause in both video and audio, while your image is displayed. We are getting to the end, now let's add a simple effect. Let's fade our video to black over the final frames. We now want to select frames from the end of our video. The easiest way to do this is probably in the timeline, although it is still only going up to ! You will see the timeline now goes all the way up to , now left click around the mark.
This will move the current frame to , in the timeline, the VLA Editor window and in the current frame box:. In the properties window, make sure the resulting effect starts at and has duration of We then want to set the opacity to 0 making it completely transparent , set Blend to Alpha Over like this:. This will add another effect the results in the color getting slowly drawn over the movie.
In the sequence it will appear like:. Finally, lets fade out our audio file. In the timeline, move to around the frame mark. In the properties window N if not on screen , scroll down and hover over the volume button, like so:. Hit the "I" key. This will set a keyframe. The keyframed value volume will turn yellow:. Now we want to advance to the end of our sequence frame for me , and this time change the value to 0, and set another keyframe. Like so:. Now if you look in the graph editor window which has been collecting dust until now , you can see a curve representing the audio falloff we just set:.
Setting Blender up for video editing
The Blender Foundation and online developer community are proud to present Blender 2. New stroke modifiers were implemented, allowing for a wider variety of user-defined line styles: Noise, Tangent, 3D curvature, Crease angle, Simplification. Have a look at some of the above mentioned features in the demo videos made by the Blender community. As for every Blender release, hundreds of bugs were fixed, thanks to the hardworking Blender developers.
