.avi file size
 

I am making animations from postprocessor of v9.3. The file size of these animations is huge ( 150 to 200MB or even more) . Any hint to reduce this file size while creating animations.?? Thanks in advance.

Re: .avi file size
 

you can select any "compression" codec before assembling the animations. FLOW-3D asks you for that. The file size is so big because it is uncompressed and high quality, but if you use any compression method (mpeg, cinepak, divx, etc...) it will become smaller as usual.

there's only microsoft compressor and i tried that. even then file size is big.......

Hi MAB i also experinced a similar issue as you. the avi file size seem to be larger than v9.2 even though with video compression option turn on. it is bugs for v9.3 again?

I usually use VirtualDub (is a freeware software) to compress the avi files. It is a very light program, no installation, it offers a wide variety of compressor format and it allows you to perform some more operations like adding logos on the movie, join two avi, etc... A very interesting software!

I am going to give a try to virtualDub .... lets hope its not virtual bug...:) Thanks stefano...

I sometimes convert the pictures to .jpg using Irfanview (also freeware) and then make .mov animations instead. I use Quicktime to view the results. Note that the picture quality decrease a bit but in Quicktime you can use your mouse to scrool forward and backward in the animation. This is extremely useful if something critical happens in the flow. The file size is reduced significantly too. Unfortunately you have to purchase the Pro version of Quicktime to create the movies but it only cost about 20$.

Lars can you provide me the link to download this Irfanview freeware? Btw, not sure flow-3d has plan to improve this feature.

I found '4u avi mpeg converter'... using its mpeg4 codec I was able to get much smaller sized avi without any noticable demage to the quality. Its also converts to other formats.

CK, the homepage is http://www.irfanview.com. It's 100% free from spyware and other annoying stuff. You can convert batches of files by choosing File -> Batch conversion. I haven't been able to find a freeware software to create the .mov files yet.

Lars Thanks for the link.

There is also an open source command line tool called ffmpeg that can be used for encoding and decoding videos. A windows port also exists. It can be used for converting videos from format to another. I would recommend msmpeg4v2 (or msmpeg4v3) codec (with *.asf file format) since it uses the efficient MPEG-4 encoding (allowing small file sizes relative to the video quality) and the playback decoder for it is installed out of box in all modern windows systems and the support on linux side is also good for it.

The downside of this tool is that it is not particularly easy to use..
