Thank you for letting me know. How do I see that it is AVI ?
As I said above this is not my area, and I have just done what a
friend advised me to do.

mencoder defaults to AVI and does not try to guess the output format

Re: Kino to compress files

Dear Dan & Dominik

Thank you for the information
It give me something to try out and work on
I must just say one thing about vesak2006
That was one of the first encodings we did, and I am not shure we used
the same script
anyway vesak2007 is using the present script.

Also the info on flash is very useful since we are just about to
convert things to flash.

with much gratitude to both of you

regards
Mettavihari

Dan, thanks for taking time to respond to this.  I was wondering if
you might be able to comment on an edit process that I have been
doing.  We capture with dvgrab, then do some fairly complex editing
with avisynth, producing an 8:3 aspect ratio video consisting of two
4:3 videos side-by-side in H.264 avi format. I like the convenience of
being able to script it all and batch the rendering in virtualdub.

But I'd like to be able to save our final version in
quicktime-compatible h.264 mp4.  Do you know of a good solution for
this?  Preferably one that can read the avisynth files directly (which
I assume would have to be windows-based), but barring that, one that
could take the h.264 avis and convert them to quicktime-compatible
h.264 mp4s.  There are so many options for video conversion that I'm a
little overwhelmed.

I am not exactly sure, but I think avidemux2 is a good thing to
investigate. It is cross-platform, supports AVIsynth, and is
scriptable.

Aspect ratio of imported still images?

Hi there

This may be a case of user severely limited in his understanding. Say I want 
to import a still image into kino, and want to keep circles "round".

I am using 16/9 PAL. I start off with an image in, say, 1600x900 containing a 
circle.

When I import this into kino, my circle is now an oval, similar to an egg, 
that is, pressed on the sides.

What should I do to make it appear a circle in kino? I tried changing size and 
resolution in gimp - to no avail....

I did try to search the docs and google for an answer - sorry if this is a 
newbee question - I seem to remember doing "something" at some point in time, 
to make this work? I can't remember what though...

Please help - it is quite embarrassing... 

Regards

Mads

Just in case you didn't try it yet: sound of a PC shutting down
(a change in cooler sound and especially hard drives parking
their heads) can provide worse sleep interruption than just
sleeping...

You might be interested in researching "silent pc" and getting
yours to be just non-intrusive.  Basically it involves energy-
efficient CPU (Athlon64 BE 2350 was reported OK, recent Core2
Duos might be good too -- didn't hear on it though), *massive*
and low-RPM/auto-regulating CPU fan, good PSU (with 12cm fan
of course), and hard drives which are more or less silent
(Samsungs are out-of-box, and Hitachis can be regulated with 
both a self-bootable Hitachi Feature Tool or hdparm -M).

A friend of mine recently reported huge success in making a
dedicated home theatre system which is turned on day and night
and one of crucial goals was "no noise"; another being "look
and perform really good", it took him ~$1000 in parts and free
MythTV plus some time to adapt it.

Unless you've got something like iron-hot Pentium 4, fan-related
measures should cost $200 at most (and probably just ~$100).

Just for the record, I use 350W/12cm noise killer Chieftec power
supply and Thermaltake "Light" series cooler right now.  Given
that there are two more coolers in full tower case with three

I just tried it, and it works fine:

0. Make 640x360 image in Gimp of black circle on white background
1. start kino
2. Edit>Preferences>Defaults: PAL 16:9
3. click OK
4. restart Kino just to be sure everything is initialized correctly
5. FX>Create>From File
6. choose file created in step 0
7. preview looks fine
8. click Render
9. looks fine Edit mode

Do you have a video loaded into Kino when you do this?
If so, what is the aspect of the first video in the project? The

Dear Dan

I have installed kino 1.3 on a test machine and found a few errors
during the installation
I also tried the scripts and also have included some errors on that

I run Slackware 11 and I have all the required lib's installed.
This machine is normally working well with kino 0.92

when I start up this is what I see.

I can save a file
I can open the test.kino file again.
I can do most other things in the program like save preferences etc. as you can se below
but I cannot open a .mov file or change a dir

When I change try to change Dir or open a file or do drag / drop of a file 
then the program will crash with the errors given below
