Paul Caggegi has updated his super populer video editing tutorial for Blender 2.78!
Hi Blendernation! I've recently released a new two-part tutorial outlining how to edit video using Blender. In the video, a free python script is applied adding a keyconfig which remaps shortcut keys to be more like Final Cut Pro or Premiere.
I take the novice from initial project set-up, through customising the Blender interface, adding media, transitions, working with meta-strips, and even editing audio.
This is a start-to-finish, easy to follow tutorial which requires no prior knowledge of Blender. A link for downloading the Python scripts is supplied in the video description.
I'm curious about final render times. An hour-long piece, with colour correction on each clip, took about 24 hours to export from Blender. On the same box, projects in that series took about 4 hours exporting from Lightworks, Kdenlive, and Flowblade. Have you found the render times out of Blender, when using effects, to be longer than expected?
Yes they are longer, because all effects, any compositing, etc has to render. In general however, it shouldn't be taking 24 hours even for an hour edit. How big is your composition? What size/format?
Even with Premiere these issues occur.
Great, I'll give Blender another try as an editor, in that case. Thanks.
This should help you with exporting video
On almost every occasion I've tried, after importing footage the audio track is a different length to the video. The only footage that has ever been reliable is 25p from my Canon 550D SLR, whereas stuff from a Panasonic TZ-7 compact seems to have an audio offset built into its files. In Blender, there is the Timeline window's AV-Sync option, the Scene panel's Audio settings area, plus some more Sound settings in the System panel of the User Preferences window. I think a video devoted to sorting out audio sync problems could be useful...
In the Timeline window, next to the playhead, there is a panel which is labelled "No Sync" by default. Switch this to "AV-Sync". Provided your video and audio is the same across all media (ie: all video is the same framerate and all matching audio the same bitrate) this should solve the issue.
I show you how to set this up to facilitate playback in the tutorial, and it should solve any render issues as well.
Other than what Paul suggested, it usually helps if you determine fps in advance, then set that fps to the rendering settings in blender BEFORE importing the audio/video clip. In this way, the imported audio/video tracks usually have same length.
But it could also work after, according to this answer on BSE: https://blender.stackexchange.com/questions/43298/video-editing-audio-and-video-strip-have-different-length
Thanks, an interesting read.
