Flash != MPEG4?

Here are the specs from the client's client's client's technical people:

Video + Overlay. Overlay not to be progressive JPEG.
Size – each video to be under 10mb. (try under 5 mb – if possible)
Sample rate this is a multiple of 11.025 KHz. Sample rate must be lower than 48Khz. Recommend 22.050Hz. Sample rates not in a multiple of 11.025 KHz will need to be rejected.
Keep encoding bit rate low (16Kbps – 32kbs)
Video codec to use: MPEG4
Video size: 16:9 aspect ratio
- Ideal lxh (small) : 250x140
- Ideal lxh (large) : 450x253
Image depth:
· Try 8 bit first and go to 24 bit only if quality unacceptable

Now by my brief reading of the info from the on2 site Flash is not mpeg4. And yet I was given this job to encode to Flash using the above specs. Have I missed something?

Looks to me like the standard 300K FLV broadband setting with a modified audio to 32 and an upped frame rate (from 12) would do the trick. Don't know about the mpeg4 business, probably neither do they.

Thanks,
I might go back to the cleint's client and see if they want me to deliver it as Flash to all those specs minus the MPEG4 part.

Thanks again,
bought the on2 Pro encoder and all seems to be turning out OK.

Then again that encoder is one buggy piece of code. The codec might be great but the code around it could use a serious rewrite. I forget how good and stable Vegas is until I have to wrestle with these kinds of nightmares.

I should also mention their licencening stinks.
Installed it one one PC, it seemed to hang on the splash screen forever so I re-installed it. Same result. Tried to install it on another PC just in case. Ha, no sorry you've exceeded your installation limits, please try resetting your install counter. Jumped though that hoop but still no dice, that only permits you to re-install it on the same PC. Would have taken a phone call to the USA to get this fixed.
Fortunately the install on the other PC finally ran, the eternal hang was caused by it trying to phone home to check for upgrades and home wasn't answering!

So finally it runs but trying to batch encode, yish, if I'm very careful and follow a very narrow path I can get it to not crash.

Bob,

Did you try Super? Even the freeware version sweems to work well for the purpose you stated. It is also not buggy on Windows XP.

Not sure if you can return on2 or not, but Super is worth a try especially for free IMO. The website has a good FAQ section. Your screen size needs to be a minimum of 1024 x 768 to install and view Super.

I had downloaded Super quite some time ago but could never quite get it do to whatever it was that I was trying to do with it at the time. I should put some more time into it, along with a zillion other things.

Anyone John, thanks for reminding me about Super. On2 has encoded all the files, just took more coming to grips with how to work around the bugs than I think is reasonable in something you have to pay for and comes with enough DRM to keep Fort Knox safe.
