Distortion..

[shikodesign2000]

Hi,

 

I have a problem in my present project, it's an interior animation of an appartment, I'm using the famous way: calculating Light cache+Irradiance map for the whole animation then rendering the final sequence.

 

My problem is: I find a lot of distortion in the final video, I don't know why?

 

The resoultion is 640*480, the compressor is "Cinepak Codec by Radius"

 

The image sampler is: Adaptive subdivision

 

The antialising filter is: Catmull-Rom

 

I think the solution is in the AA filter, and I must use blurring filter, if this true, can I know what is the best blurring filter? Video or Area? or something else??

 

And is there any other options are important in rising interior animation generally.confused:

I wouldn't use the cinepak codec, I bet that's the reason you're getting a lot of distortion.

 

If you can, render out each frame as a .png or .tga then put those through software like combustion or after effects.

 

If you can't or do not have that software, try the windows media 9 codec. I've generally found that it's better than the cinepak, though you still will get some compression issues.

Ok, I rendered 150 frames as test with .png extension, then I merged them in "combustion" into 1 video file with extension .mov for quick time player.

 

The quality is very good , but the file size is very big: 119 mb, I think the solution is to compress this file:confused: or I'm wrong?? and I had to produce the sequenced files in "combustion" to another extension, (not .mov)??

 

What have I do to produce a reasonable file size with good quality??

Use divx

i like the option of buying quicktime pro, and using it to stitch together individual frames. you can use import an image sequence and export it out to specific parameters. I tend to use the H.264 quicktime compression, it is excellent. also, since it saves out as a quicktime movie, it can be viewed on most computers. Apples come with quicktime installed, and most PCs have it, altho i have found that some of my client's workstations wont allow quicktime movies, they that doesnt happen often.

 

you can also save out to H.264 compression thru Adobe Premiere, but i havent really used it that much in all honesty.

 

Good Luck!

Do you mean that this way can produce high quality with reasonable file size??

[Tommy L]

Depends what you mean by 'high quality' and 'reasonable' filesize. If you compare anything to uncompressed you get a reasonable filesize.

So....have you tried divx?

I just use Combustion to import (the 150 .png stills) then merge them together and specify divx as codec exporting, but the result is the same as I rendered them in max with divx, very low resolution.

 

I just liked the quick time quality, but the problem is it's very big size, 95 mb for just 150 frames, I have about 5500 frames for all the appartment!!

 

I'll try the h.264 quick time compression and see if it'll work or not.

I found that when I use Quick Time pro (the last version), I can export the big (quick time file 119 mb) which I made it in combustion and produce very similar quality and very good size 4 mb, a very few differences between the 2 versions, I think this's the best solution, if anyone knows better solution let me know.
