We need an MPEG-4 Encoder
by James Diefenderfer on Nov 7, 2002 at 2:16:11 pm

Can anyone direct me to a company that makes an mpeg-4 encoder WITHOUT a player attached. I am working with a US
Government organization that is working on new compression project and they are looking for just an encoder to work
with. I am doing the google search but I wanted to find out what the COW had to offer.

Thanks

I guess I don't understand the question. If you encode an MPEG-4 using Cleaner 6, it will be compatible with all MPEG-4 players since the resulting MPEG-4 file is ISMA compliant; which assures interoperability. Some vendors like Envivio and iVast have made command line encoders - is that what you mean? There is at least one vendor that allows an eval period of their MPEG-4 encoder - dicas. Maybe that's what you want? And there is one company, Sigma Designs, which is giving away a software MPEG-4 encoder. All of this info and much more can be found at what I call "MPEG-4 central" a.k.a. M4IF.org
Hopefully one of these answers addresses your question. Happy compressing!

Jeff- thanks for that link - not sure how I missed that one. It has everything that was needed.

Just be warned that QuickTime (and hence Cleaner) has a pretty limited MPEG-4 encoder. Check out iVast and Envivio for higher-end products.

I'm in the middle of a big MPEG-4 encoder shootout for a client right now, myself. What Profile@Level is your player targeting.

Ben,

I will get back to you with that answer Tue or Wed. I am only doing the research for my cube mate. Is that 'Profile Level' ?
The project is just to show that by encoding with MPEG-4 they can move more data (UAV footage) though a given
bandwidth pipe. Believe it or not the USAF does not encode a lot of stuff because they never had a lot of data before. Now
that more data is being used they need to find ways to use the available bandwidth better.

By the way - thanks for clarify the RealPlayer vs FlashMX webcam issue (via eMail) and I enjoyed the book very much. I did a COW review but Jeff put his own up before mine got posted.

Thanks for reading this far !

The profile and level is the conformance point of MPEG-4. A given player will support a given Profile (what tools can be used in the codec, like B-frames) and what Level (maximum values of parameters like resolution, frame rate, etcetera). So, basically, you have to pick your player, and then figure out what tools make the best files for that player.

MPEG-4 today doesn't offer compression as good as the propritary formats. This should change with MPEG-4 Part 10/H.264 next year.

Anyway, if this is a funded project, I'd love to pitch my consulting services on it!

As for Jeff's review, I only saw what he said about the first few chapters. Did he ever review the rest?

Ben's book

"As for Jeff's review, I only saw what he said about the first few chapters. Did he ever review the rest?"

I'm through four chapters. This book has an incredible amount of valid and detailed info and very little fluff. That's good, but it makes for long reads. I think there is enough here for a series of smaller books, really. I honestly don't know how you and your editors did it. Anyway, it's going to be a few weeks before I can polish off the review if I'm to actually read the entire thing. BTW, I intend to do just that. Kudos to Ben! If you can't wait for my review then my suggestion is: Just buy it! You won't regret it.

Actually, in light of what I just said; I could release the review in "byte-sized" chunks revealing the chapters as I go. At the end, I could simply compile all of the cumulative reviews into one big one. What do you think?

Ben,

I passed on the info and yes the project is funded. I have passed on your interest and I will let you know the response.

Thanks for reading this far !
