Animation stalling

[ZFact]

Hi all;

I have a meeting tomorrow with client re: an animation. I have used a sorenson codec

but not sure whether to use sorenson or sorenson 3? He will be viewing this work

on his PC using quicktime.

The animation is 150meg when compressed, it plays fine on my machine probably

because some of it is a cached file. However if i play on a new machine it tends

to stall alot, if i play it once or twice over it must cache as it plays smooth everytime

from then on. What can I do to make this play smooth first time round?

Cheers

Paul

You'll need to reduce the quality of the animation in the codec in order to get a smoother playback.

i played it on a third computer just now, and it plays fine first

time on that... why is this? Is it something to do with the

graphics card.

 

Whats my alternatives for presenting this to the client?

 

Thanks

There are all kinds of factors, speed of hard drive, CPU, Memory and video card. The faster the computer the better it will play back the material, unfortunately there isn't one codec you can use that will insure flawless playback every time.

Ok;

I just reduced the quality of compression to its lowest

setting and compressed the music and it came out

the other end an even larger file. Up now to 180meg??

 

Why?

What compression would you use Devin and at what setting

in order to achieve maximum quality but generally play back

smooth on most machines. As this animation will be sent

out to the masses eventually.

 

Thanks

What program are you using to compress the animation?

Adobe After effects

I recently had to get a 7 min anim. to play directly from CD on various pc/laptops using windows mediaplayer at a resolution of 1200 x 900. I found that a .wmv file encoded to 8000 kbps would play back well on all but the oldest of machines, however there was a noticeable drop in quality if a different player was used (quicktime, real, etc). Hope this is of some help?

Try using the H.264 Encoder with the bitrate set at 90,139. Kbps

thanks;

but my file siz e has now gone up to 215meg, shouldnt files size come down with higher compression?

 

Why a bitrate of 91,139 kpbs?

I think your decreasing your compression instead of increasing it, if you’re using the H.264 codec you are also getting a better codec so the file sizes may be bigger. To answer your question yes higher levels of compression usually mean smaller file sizes but the quality will also get worse.
