Posts: 92 		Hi - could the forum take a quick peek at the 30 sec clip here http://1drv.ms/1g7oK5d and notice that there is a "shiny gloss" / rainbow circles on:
1 - the middle, brown toon building
2 - the "Apt 3A" wall
3 - the toon door being opened
My settings are:
I've turned my "Ambient Light" setting to "0"% and only using "Directional light" combined with "Point Light" - for sure the "Point Light" is causing the shininess on the apt 3A" wall...but why?
My Make Video settings are: output: "Video"; Codec "Microsoft video msvc"
My video card is a NVIDIA GeForce GT 630 (pretty decent card - no?!).
The frustrating thing is that this doesn't show in the MZu camera view - only after rendering - so it's a bit of a pain to trouble shoot...any help or insight is greatly appreciated!
thanks,

Most of us use either uncompressed video (limited to 2GB before going haywire) or targa sequences which need to be put together in an external video editor. You could get more codecs but this is risky because they're often from shady sites where you can pick up malware.

Posts: 92 		I rendered the clip again using uncompressed video and that did the trick - thanks MDW13 & ukBerty for the quick and helpful replies!

It won't play if it's over 2gb - it's a problem with the version of avi Muvizu uses. You could render small (20 second?) segments, and if that doesn't work, have a go with tga.

The codecs compress it so it's not so big, but some (especially the microsoft one) take it out on the quality of the output.

Posts: 92 		Ahhhhhh, so glad I'm not (completely) insane....a few weeks ago, I also couldn't play the uncompressed format and that's one of the reasons why I switched to the Microsoft video msvc codec...then today...I did a test clip (having forgotten my previous failure) using uncompressed avi for a short, test clip (10 secs) & it worked...then I did the larger clip (1 min & didn't think it was 2G as you previously warned) and it failed...reminding me of my previous failure and leaving me scratching my head saying "but wait, didn't this uncompressed avi work an hour ago?!"
Ahhhhhhhhhh....
Thanks for restoring my sanity!
Back to rendering shorter clips in uncompressed avi.....

Posts: 92 		Ok...now from the frying pan into the fire...I just did the math...only being able to do 10-20 secs at a time when each of my scenes are 1-2 mins long - 1) I'm afraid it will not be seamless and look choppy after editing 2) that's snot load of space 2g per 20 secs!!!!
What are other options? Use tga? Can you educate me a bit on the other MZu video option pros & cons?
Can I use Nero media software to edit a tga? Will the end quality be as good as the uncompressed avi?


thank you, thank you...

I have yet to ever create a scene that hits one minute long and I have allergies to muvizu cameras even then its unusual for me to not cut to another camera within 20 seconds... I just dont move them whenever possible..
