Photorealistic animation

How do I animate and obtain the photorealistic image quality of a stillife
render?

Even when I set the resolution to 1280 x 1024 the animation still has a
'blotchy' look.

How do I get optimum image quality from my animations?

 

Try increasing the frames per second (FPS) setting when you set the file to
save. I would use a minimum of 15. I believe your typical movie (in a
theatre) is about 30-40 FPS.

 

Solidworks is terrible at image compression. Try rendering with an
uncompressed format, and see if it changes your blotchiness.

 

Thanks for the info Jerry. Sounds like you know your film an TV.

Sorry if I made myself unclear. Its the image quality that I cant seem to
improve. The image colour seems washed (as if it has a watercolour look) out
not pin sharp as with my still-life rendering.

 

Sorted it now. It was the compression setting. If I have no compression then
its fine.
As a matter of interest what is the best compression setting to give you the
best results?

 

Basically, for TV they duplicate some of the frames. It's called something
like 3:2 Stepdown. Since 30 and 24 are both divisible by 6, for every 5
frames in the TV, you've only got 4 frames in the film, so one of the 4 gets
duplicated. How 4:5 got a name like 3:2 is way beyond my ability to
understand.

Hi,

My 2 cents...

A Motion Picture Film Projector may actually run the film at 24fps, BUT the
projector flashes each frame twice, so the result is 48 flashes per second.

The reasoning is that while the temporal information can be at 24 frames per
second (each image that changes) the eye will perceive flicker, especially
when the dynamic range between dark and light is maximized, like in a
theater. Human eyes (amongst others) suffer from contrast sensitivity. So
to reduce/eliminate that effect, on playback the film projector flashes each
frame of film twice to raise the apparent frequency of strobing and thus
reduce the apparent flicker.

Note: A incredibly beautiful film to video format exchange is frame to field
transfers, where the subject is filmed at 60fps and the film is transferred
to video such that each film frame is one field, the resulting video
images/pictures are awesome.

Likewise, a DLP projector "chip" is always refreshed at 60fps. So even
though the image may be at 1080i, the actual image you are seeing is not
1080i @ 30fps but 60fps, still interlaced but at twice the frequency. There
is a new advertising campaign going on for the last 6 months(?) that has
focused on 1080p, actual frame updates at 60fps. The DLP system can be very
complex given that the time per RGB value is clocked at very different
rates, and the DLP Pixel (MEMS element) can move at 50,000 tilts per second,
and the newer generation DLP chips at 100,000, quite astonishing really. In
actuality some pixels may refresh at up to 96hz, but DLP timing is a complex
discussion for here, contact me for more info.

But as usual I digress...

My preference minimum is 640x480 @ 30 frames per second (~ broadcast
quality) no compression to a maximum of 1280x1024 @ 60 frames per second no
compression <-- now that's allot of render right there! Now the new worry,
a $olidWorks render farm!

Also, the American Cinematographers Guide has various tables, including
those for maximum pan and tilt rates to avoid what was an original question
further up this thread (blotchy renders, maybe related to choppy pans???),
can't find an informative link on that right now.

So for nice looking motion renders all of this must be taken into
consideration, and all will look like you were an ASC award winning
cinematographer in a $100,000,000 movie!
