Big “oops, I deleted that”

November 25, 2008

Just realized that I accidentally deleted the editing files for a very short film I was working on. ;(  This means I will either have to start over with the editing process (I might still have the PNG title sequences) or give up on it.  I lost all other .blend files I was using with BlenderAVC before I moved my hard drive to this PC as well. 😦

So, in other words, oops. 😉

I am also realizing that shutter speed and frame rate are two totally different things. LOL.  Yeah, I know, I may sound amateur, and I am, but I am learning… some. ;D

So, for now, adios!

P.S. I will most likely not complete NaNoWriMo this year (2008 for those of you who have lost track) because I did not spend enough time on it, and I am only to about 20,000 words so far.  Hopefully I will get 25k before the deadline hits.  Oh well, there is always next year … and this January (2009 for those of you who forgot about the New Year) three of us will hopefully be doing a “homemade” NaNoWriMo – same goal, different month.  This means more writing for me, so that’s great… You can still see my NaNoWriMo user page here. Ciao!

Blender green screening, VSE – and how to make your own greenscreen!

June 8, 2008

I am endeavoring to learn some of Blender’s (blender.org) VSE (Video Sequence Editor) and node compositing editor.

With the VSE you can arrange video clips and do effects, such as achieving a fade out to black (using three strips – video, gamma cross and color generator.)

Using VSE as a simple video editor may be very useful, and as it develops hopefully it will overrun such commercial monster products as Adobe Premiere Pro.  One advantage over Premiere Pro 1.0 that I have found is that Blender’s VSE accepts an .avi compression that I use, whereas Premiere Pro 1.0 doesn’t.  Besides that, Blender is completely free and open source, and is an alternative to Windows Movie Maker.  WMM can be very useful for shrinking file sizes and doing some simple editing (and you can do text effects and transitions,) but Blender’s VSE seems less dumbing.

And now about the greenscreening:

With the node compositing I am endeavoring to make a successful chroma keying – taking out a certain color, like bluescreening, also known as split screen – but it is proving quite a bit harder than I hoped. It seems (as is perfectly logical) that to have an effective keying I need very clear, pure colors to key out. Otherwise you get grays when it looks blue and your footage becomes very spotty.

Hopefully I will get some good results soon. Here’s a screenshot of my first work with chroma keying – overlaying a video on an image – not so great, but I’m learning.

Also, doing further testing this evening, this chroma keying business may be much more difficult than I had hoped. Looking online for professional options, I found these two sites: (the first site recommended the second site.)

DIY (Do It Yourself – Bluescreens, Greenscreens, Backdrops and Background stands) Highly recommended to check out – you can find out about how to make your own greenscreen the cheap way. (not fool proof.

EEFX (green/blue screen backgrounds and backdrops(?)) Great for seeing professional quality equipement, seeing the prices, and learning about what makes their cloth special.

Hope you enjoy – looking forward to filming soon! Praise God!
