Globes distorting

Post by m rixon »

I have created a rotating globe that appears perfectly round in Cool 3d but squashes down when rendered .My settings are
1.720x576 background when creating the orb.
2. 24 bit Microsoft avi ,720x576 ,16:9 25fps
Frame based
DV video encoder type 1

I want to display on a 16:9 aspect Pal tv,
How do I retain a round globe when rendering please.

Widescreen animation should be dimension size 1024x576 for PAL. Render out with Compression:None Frame-based 24 bit AVI. Once completed, import AVI into NLE using PAL 16:9 DV project settings. The globe will retain its roundness.

BETTER YET....

Save the 1024x576 animation as Compression: None Frame-based 32 bit AVI. This way the background is transparent and you can use your 720x576 image as an overlay in your editor. Make sure to use the PAL 16:9 DV template in your editor.

rwernyei; I will try your suggestion and repot back.In the meantime I have saved the 3cd file from Cool 3d and rendered it in MSP8 .The globe remained round and rendering took 3 mins. whereas in Cool 3d it would have taken 30 mins.However I lost the bacground and had to use the c3d file as an overlay.
You say your suggested method also loses the background .Whats the point in Cool allowing use of say its video background facilities if it cannot be retained in the 16:9 format ?
What is NLE ? (import AVI into NLE using....)

rwernei;Used the following settings
Microsoft AVI files
24 Bits, 1024 x 576, 1:1, 25 fps
Frame-based
Uncompressed
No Audio
Result is perfect with background retained but rendering took over 1hr.Quality is much higher than those I rendered in MSP8.
Many thanks for your help.Would still like to know what NLE is.

I'm glad to hear the settings worked. The reason why I use 32 bit for my renders is because it saves the file with alpha channel. This makes the background transparent. Allows me to use my animation as masks, multiple overlays, etc...

NLE=non-linear editor

rwernyei;Now that I know what NLE means do you use the same 1024x576 setting when saving edited AVI in mpeg format prior to creating a DVD ?I have always used the 720x576 16:9 format option,but have not been impressed by the quality.
I edit in MSP8 and create a 24 bit,frame based mpeg file fpr authoring in DVD Movie Factory 4 .

Have just checked in MSP8 there is not an option to choose 1024x576 and I don't know how to alter the "USER DEFINED " option.
I am still concerned about output quality if there are better setting than those I am using.It seems a shame to lose the quality I am getting from Cool 3d.

DVD MPEG2 standard for PAL is 720x576, this is why you cannot change your output settings. In MSP8 put all your clips including uncompressed COOL3D 1024x576 AVI on timeline, edit and save .dvp. This way you have your .dvp project and can revisit it later if needed. If your main goal is for your project to go to DVD, from your .dvp go directly to Create Video File step and create your MPEG2 file. Adjust settings under Options for best results, data type, bitrate, etc... Try to preserve the quality by not doing needless AVI renders before going to MPEG. The quality will degrade with every render.
