It's a good idea to point to the new data with the same length. VIDEO STRIP: Simple Cross Fade You could do Fades by keyframing the Opacity (inside Properly subpanel) of any particular Strip. Keyframing on any parameter value can be done just by pressing I while hovering on that value. Actually the animation is quite straightforward once you understand. But, there is another way, which does not require keyframing. Follow the steps below: 1. Firstly, you generate a Color Strip block of just a simple Color. Shift+A (add), Effect Strip, Color ~ This Color strip is set to Black color by default, but perhaps you want to fade into certain color, you can change that easily under via the Property panel (N). Color Strip can be any color you want. 2. Set the Strip block so that they are a little bit overlapping each other at different Channel like shown below. The area where they overlap will be where the Cross fade will happen. Prepare the overlap for Cross fade. Now, all you need to do is to select both 2 strips (Shift + RMB) and then add *Effect Strip - Cross.~ Your channel will now looks like below. Based on our common understanding of layering, the higher block in the channel will cover the lower channel at the bottom. The Cross effect added at the very top. Ensure that Blend is set to Replace on the Property Subpanel and now you can have a nice fade from that Color strip into your other Image Sequence or Movie Strip. 3. You can also create Cross fade between 2 videos or image sequences. AUDIO STRIP: Simple Volume Fade In and Out For Audio, to make the volume to fade in, you do that by keyframing the Volume parameter. Keyframing is not difficult, you just simply create 2 keyframes, one to key the Volume at 0 and the other to have the Volume at 1 (default volume). Blender will create graph curve that will interpolate the volume in the background. AUDIO STRIP: Draw Waveform ~ This option is available inside the Property subpanel. Select your Audio Strip and activate Draw Waveform. MORE VIDEO EFFECTS ~ For any of your movie or image sequence Strip block, you can check some available effects available for you. Select your Strip first, and then Shift+A (to add) and select Effect-Strips ~ Try all the different effects and filter available. Maybe you want to use *Glow effects or even Transform and animate* your video. There is also Speed control effect to *speed up or slow down* your video. BLEND: ALPHA OVER ALPHA UNDER ~ Let say you want to have a setup where you want to have Video or Image Inset on top of another. So, for any video you want to inset, you certainly want to Scale down the size first. You do that by using Transform Effects. Do Shift+A (to add) and select *Transform* Once you do that, there will be effect strip on top of your Video/Image strip. Now, you can Scale, Rotate, Translate and animate your video basically. But you are not finished, you need to turn on Alpha Over and Alpha Under, this is to ensure the Blender understand the video is modified and it will create Alpha (transparent) on top of video below it. Once you set this, your Video Inset is ready. Transform Blend = Alpha Over (Upper layer) Video/Image Blend = Alpha Under (Actual Image/Video) Remember that when using Effects Strip, watch the Property subpanel (hit N) and experiment with different parameter and settings. You actually have Color Balance adjustment also inside the Property subpanel. Blend paramater is certainly one that is important key when you are doing layering of one sequence strip on top of another. Similar to Photoshop where you can have different kind of Blender, here it is also you need to consider how one strip will blend into another strip. PLUGINS http://wiki.blender.org/index.php/Doc:2.4/Manual/Sequencer/Effects/Plugins EXPORT / RENDER OUTPUT By default, Blender will render out at 1920 x 1080 but at 50% of that set resolution. You can see this if you switch to Default 3D View Panel, and check under Properties panel. Blender by deafult will also render out image sequences as PNG sequence, and without Alpha (you need to set to RGBA if you want alpha channel to render) at the temporary folder called TMP. Just change this under Property panel into what format you want Blender to output it out. Clicking on Render - Animation will output your final sequence as the format you like. CTRL-F12 is the hotkey to render animation. Select the format you like to output the file as. I usually export this out as AVI Raw for maximum quality and then I will compress it using FFMPEG. But you could also just render it out from Blender as AVI MP4 compression. Output settings for Video and Audio. That is pretty much what I like to share for basic Video and Audio editing using Blender Video Sequence Editor. Hopefully this post is useful for you. You should now be able to edit, remix and produce some videos using Blender.

Tip: Key Frame = Any Frame number where transition takes place ? Tip: You can add speed ramp strip for slow motion. Tip: Great tutorial about making highrise building using blender: http://vimeo.com/13123241 Blender tutorial: blenderguru.com/high-rise-building/ Tip: Use only standard size videos and images!!! (800x600 etc). Otherwise you may see ffmpeg refusing to process. ??? (not sure). ======================================================================== - Press Middle Mouse and Drag (not scroll) to drag menu items to view. How to Video Edit ======================================================================== - In the top "Info" View, Select from the drop down 'Video Editing'. This is the layout name. You can create your own layouts and save them. - I am going to import couple of videos: install1.mpeg and install2.mpeg Dimensions: 880x610 10fps - Before you import video into the timeline, you set the format in Panels window with proper fps (frame per second) setting. Otherwise the audio will go out of sync. - In panels thereis a little box which says "Scrub", if you enable it, you can preview the scenes ??? - Audio(Hd) means keep audio in hard drive - Set form to 720p
