Can some please help me.

I have a 30 second advert. The brief states under 100MB in size once compressed and in a codec playable in university (DivX prefered).

I am ready to render the video. I tried choosing DivX from the list but once rendered would not play in windows media player. Stated "codec required". I do though hax the DivX codec installed as I have seen other DivX movies.

I want the upper most quality from this file while keeping under 100MB. Can I have some recommendations and advice on why DivX will not work for me?

I'm no Divx expert, but I believe you need the Divx encoder, NOT just the player. Not sure if you already have it, but it's a seperate download from the Divx site (http://www.divx.com/divx/) and costs $19.99.

Also, in my opinion it's a really bad idea to render out directly to Divx. You should probably render out of AE in an uncompressed format such as Animation Codec, then use the Divx encoder application to make your Divx file. If it's under 30 seconds then staying under 100MB should not be a problem at all.

Also, did THEY say Divx prefered? I'm assuming that even though you said advert ,you don't mean it's actually for broadcast...

University Project. Definatly not for broadcast!

Ooooo, then DivX is out of the question then. Can you advice any other? Im getting the file at around 100MB using Sorenson 3 < think it's named that but the quality is noticeable lower than the full 800 MB uncompressed. Only option I have is to export and compress from AE.

quicktime mpeg4 is pretty darn nice. I'd suggest you take a look at:

An incredible little program, and yes it can compress to DivX.

Hey thanks for the cool link Ian. I am checking this prog out now, seems pretty nice. Can't beat free!

And yes, I would agree - Mpeg4 is a good choice, I also like Sorenson 3. The trick with Sorenson is in the settings, you need to experiment with different data rates etc. to get good results. If you want to use Sorenson, try these settings for starters:

1. 2-Pass VBR (Variable Bit Rate) - you should almost always use this setting, improves quality and size
2. Keyframes - leave this on auto if possible, OR set to around 5-10X your source file's framerate.
So for 29.97 video set keyframes to around 300.
3. Bit Rate - totally depends on the medium this file is destined for. If it is to be played on a computer, then you can probably get away with a data rate of at least 1,000k (cdrom quality) or more. This is where the most experimentation is required with any codec to get the smoothest results on your playback device.

Good luck!

If you want to stick with divx, the free download version (divx Play) at www.divx.com (http://www.divx.com/divx/) has the codec included, which is all you need to make divx files. The charged version just includes their own converter to make things easier, and a pro version of the codec that you probably don't need.

As for encoding the movie, steer clear of direct divx output as if it screws up or isn't high enough quality you have to re-render. I'd recommend a free program called virtualDub at www.virtualdub.org (http://www.virtualdub.org) or for download at http://virtualdub.sourceforge.net as it is the best free program for making avis, and can import .bmp or .tga image sequences from your rendered output. It has a bit of a quirky interface, but there are plenty of tutorials out there. Feel free to email me if you're not getting anywhere.

That's right, I forgot the pro version just has an "allegedly" faster codec with more options, and yes their own converter. I don't think I've used Divx in 4 years so I would be the last person to comment on such things, even though I did ;)

I just noticed this is in the After Effects section, so you don't need me plugging virtualDub!

Sorenson and QT mp4 are great codecs, but I think divx wins out as more Windows PCs can read it. As beenieweenies says, I guess what you use should depend on what your university wants.

I'll leave you to the pros *gets coat...*

Sorry but this simply isn't true. Sorenson is included by default with Quicktime AND Windows Media Player AND Flash video (the most ubiquitous of them all), whereas Divx requires a user specifically going to thier site and downloading it. Am I missing something here?

Sorry, my bad... The only version of sorenson I've noticed has been used in .mov files, which need Quicktime to run (itself a bitch of a download, what with iTunes bundling, and restricted non-pro versions etc.) I didn't realise it's supported natively by Windows Media Player these days...

I stumbled onto this After Effects thread following one of Tezler's 3D modelling threads, and ended up a babe in the woods of video codecs... ;) I knew a bit about divx so thought I could help out, but didn't intend to fan the flames of a codec war I know nothing about!

Peace, Y'all... :thumbsup:

yeah the bundling of iTunes with QT is a pretty lame idea, I don't know what they're thinking. At least now when you download iTunes updates it doesn't default back to QT standard, forcing you to dig out your serial number and re-enter it... That REALLY sucked!

Hopefully my post didn't sound too harsh, wasn't trying to bat you down! Just pointing out Sorenson has a pretty wide user base...
