How to properly output FLV’s from After Effects?
Hi Folks,
I want to output an FLV movie from After Effects to show in Flash Player on a website and I want it to look good! The only problem is that so far the FLV outputted looks bad!
I have a fairly big movie – my comp size is: 880x 496.
I want to make a FLV from this comp, keeping the size the same (880×496).The way I’ve been doing it is not giving me good results…the resulting FLV always looks grainy or low resolution…
From After Effects 7.0 I’m using: File > Export > FLV and even when I use a high encoding profile (700kbs or higher – Video Codec: On2 VP6) the quality is bad – the image looks grainy or low rez.
Currently my FLV file size goes up to 5MG and it still looks bad…
The duration of the composition is about 40 seconds, so already I’m thinking this is too big. But apparently I would have to make it bigger…Now I came to realize and on Creative Cow, there are very long video tutorials with a large comp size of a very good quality!
So it is possible to have a good, quality video of a reasonable file size…but how?
How does Creative Cow do it?
Or what would be the best way to output a good quality FLV from AE, and to keep the file size low? Should I use a different setting…or a different export option…or maybe some other software? Should I forget about FLV’s altogether and use another file format?The bottom line is, I want to show a video in Flash Player…and I want it to look good!
Thanks for any insight,
Regards,

well in order to export from AE, you usually do not use the “export” thing.
You use the render queue (I have French soft so I don’t know the exact name) so you select you composition in the timeline, then you can go with the shortcut: Ctrl+Shift+< then in the "module de sortie" (so something like "Output Settings") you click the yellow link saying "non destructive" and it opens a window. There you open the scrolling menu "format" and select Flash Video. Then you go in "format option" and do your thing. Quality has to do with the bit rate settings. I go for 2048 most of the time + OnVP6... the renders are perfect that way...

If the file size is a big concern for you, I suggest using other software. Adobe products do not offer 2-pass encoding of On2 VP6 codec. Programs like Sorenson Squeeze can do 2-pass, which can cut your file size almost in half without any loss in quality.
Your file will most definitely be larger than 5MB for a 40 second clip at that resolution (with decent quality). Just as an example, the promo video for my Texture Packs has a duration of 53 seconds, a resolution of 386×216 and came in at 3.62MB.

Your video has 5.2X the number of pixels than my promo video has. Even though its not quite a linear equation due to compression algorithms, your video is expected to be in the range of 11MB – 14MB at a decent quality, with variable 2-pass encoding. With single pass encoding from After Effects, expect it to be even larger.
