Introduction to Sequence Editor in Realvideo 13 minutes

Post by thorax »

(realvideo, PS- if you have zonealarm, you can give realshed.exe zero
access to the net, it works for me and prevents ads.. There is also
options in the new realone player that you can use to turn off a lot of thje
annoyances.. I use realvideo because DIVX still isn't this good for me
at 64Kbitstreams, although I master in DIVX..):

http://www.bl3nder.com/BlenderSequenceEditorFast.ram

(to download the video, use the same url with just ".rm" at the end..
Enjoy..

PS-
I did this tutorial literally in the last 30 minutes, its 13 minutes
long and quickly introduces one to Sequence Editor (blender's Adobe Premiere-like compositor program, actually I don't know if its like
premiere).. Anyhow, some things I left out, you can find in the
blender manuals.

M-key is meta key..
Alt-M unMeta's something..
Shift-A is your add menu..
Most all other commands are the same as in all of blender
for zooming, grabing a clip in G-key.. Also you can
append a scene in the append menu, make sure you select
the "scene" in the blend file you append when using a
scene as a clip.

If you have anymore questions, get a copy of the blender 1.5
manual, it should be in there.. Or ask someone else.. I hope
this at least helps those who are trying to do animation work
and have need for a video editor.. Also get a copy of VirtualDub
available on sourceforge, or use google to get it, one nice feature
in virtualdub (that I really like) is combining a AVI with audio
without recompression.. Very cool feature..

Anyone interested in any other tutorials?

I'm going to try to create a set of quick realvideos for the
website, that can be used by new Blender users as
kinds of quick tutorials on blender..

If anyone has a particular interest, preferably not with Game Blender,
which I don't know about, I can get some tutorials made..

yes. Please do not use real video. Use Divx or mpeg4 or avi or 3ivx or even
mov.
Please let the rest of the world see them.
There are just to many apps out in the world. We all need movies that can
be seen with the most basic of softwares. So no need for more downloads.
And FAR les need for more apps with crapy ads and spam mail.

^v^

I second that, a big thumbs DOWN to realvideo...

And don't even think about .wmv, .asf or any other M$ format, mpg and divx is IT.

Run linux. Use mplayer. All your video format problems go away :)

The most important thing to say is: thank you for your time!
It's nice that somebody tries to teach others the dark way of the sequence editor.

Otay Einstien I dare you to try compression with DIVX, I use DIVX
and Realvideo I have done th tests, DIVX does well at high bitrates but it absolutely and positively sucks at modem rates..

thorax,
I have been using camstudio to make Blender Training Videos. I am teaching Blender at a local college. I plan to make them available on a server soon. I am still experimenting with different compression formats too. I appreciate your efforts. Perhaps we could coordinate a bit if you wish. I will check back in this thread.

Here is a sample - best to download rather than try to open online. It is not streaming video.

7.4MB Windows MPEG4 compression

Well I could tell from the video that it looks very professional,
but I was more interested in getting something together to get the users interested in blender and learning quickly how to use blender basically.

WEll its not so hard to get the Realvideo streaming, it shouldn't
be that hard for DIVX either since DIVX can constrain a video source
to a specific bitrate.. Just DIVX is not really designed for modem
rates it doesn't do well with variable frame rates which is how realvideo
copes with the problem, I think it also uses a cummulative-encoding
approach where screens if left idle for a amount of time get more resolute, whereas in DIVX the focus is on maintaining a frame rate so
the bits get chopped between frames.. If you've messed with low
bitrates of DIVX you've seen the flickering artifact on text.
I'm trying to get DIVX to do a multiple pass encoding where it can determine from frames ahead and behind how best to compress the video.. That's how I get the high-res in Realvideo is with 2-pass
switch in HelixProducer. If I encode straight, it doesn't attain the
resolution.. That's what I've been trying to do with DIVX
that is producing nothing but crapped up AVI files.

The tutorials I am doing are a little less formal too, I was turned on by how 3DBuzz is doing tutorials for Maya and Softimage (www.3dbuzz.com). And thought I can do that.. I actually find
it entertaining, but he is more entertaining. You could probably
stand to loosen up your style and get a few friends to cut-up
on the demo.. I figure I sound pretty dumb, but I like doing them,
I'd feel bad if I had to make it too structured, as blender has bugs
and its okay to show they exist too.. I just BS around them.. But
even Maya has bugs.. Wavefront TAV had a bug in "Render" that
was accompanied by a flag that determined how long it would render
before killing the render job and restarting it. So bugs are not something
you say goodbye to when using high-end software.. So my tutorials
are very raw, and what I learn I show, so as to not act to artificial about
the concreteness of the program. We all work around them,
you have to.. But there is no excuse for bugs, that's why I've been
informing the developers as well, we need to stress object oriented
programming.. Its not cliche and its not passe, its a proven
way to make bug-free software and it requires real programmers
not code hackers. I say no to hackers, sorry but if you want to waste your life digging your own grave be my guest.. But I don't
have interest in a grave for everyone with your name on it.

Blender must become trully object oriented, it needs to be scalable
and expandable, but without loss of its functionality and mobility..
That means say no to plugins, please don't include hooks for
proprietary plugins in the blend files.. Just because blender is open sourced doesn't mean commercial developers couldn't sabotage the source distribution.. In fact I think it is happening.. Ton and the group are
very careful this doesn't happen.. May be why they are particularly
protective against Tuhopuu and Cessen and the others developing it. I could be flipping my identities, who knows if Ton and them are trying to develop another method to leverage blender. I think the users ultimately are not going to stand for it. But the energy surrounding blender is
just too attractive to businesses.. I'm sure there are plenty thinking "how can we leverage this". I'm in there thinking the same thing..

My selfish desire is to see blender as a portal for 3D work, a way
artists can collaborate, so that I can stay at home, design 3D
objects or teach people 3D art, without having to move to Los Angeles,
and I think giving tutorials on how to use blender is just to kickstart that..
I know Eskil is looking for a way to tap into the 3D talent by creating a collaborative 3D environment, and I know the idea has been very attractive to Ton and Bart. It has to be done, it should be the focus.

Anyhow..

Well I could tell from the video that it looks very professional,
but I was ... quickly how to use blender basically.
Thanks, and I agree with you...I have since reduced the pomp and circumstance-it grows the file size too much. I have no critcism of your style and I appreciate the rundown on your efforts with real video/divx, etc... It great to see more people trying to do these training videos, we can all learn from them. I will say that I thought quality of the image in your real video was poor, but mine wasn't so good either. Not sure what the MB/minute rate was on your real vid, but it was a fairly small file... I just never have been real pleased with the quality of realvideo.

I did this late at night and had to be quite so as not to wake my kids.... I appreciate the suggestions - I have listened to the 3DBuzz tutes as well.

We share a similar vision.
Teaching sure does force you to learn it well too. Blender opened up my 3D world. Once I started using it, everything else I tried seemed clunky and inflexible not to mention..slow. High end software is now within my reach, but I have so much fun with Blender. I have been working ona Christian Animation Project with a friend. Our company site is http://www.creationanimation.com Our work is about ready to go to distributors for the big pitch....

Regarding the Videos, I will see if I can get some others posted this weekend - and I will work on loosening up my style. My students told me the same thing basically, they like it when I mess up in the tutorial - It helps them out when the run into similar situations.

Well its the best that can be done at near modem rates..
I doubt it would get much better than this in any other
compression unless I had used Flash.. I think I had proposed
using VNC with vncrecord + vnc2swf . But it wouldn't work
very well for interactive 3D stuff.. I've had need for flash for flat 3D
tutorials. Another approach would be to add sound recording support
to blender and be able to record a session of blender and play it back,
that would be really quick!!
