Re: CineForm SDK is now open source

Wow! Top news! Has been one of my fave codecs since its inception. Now hopefully others will pick it up.

Re: CineForm SDK is now open source

Thought that would never happen ! Finally some prospect of a Cineform encoder in ffmpeg. Also the existing ffmpeg Cineform decoder, that was developed by reverse engineering, is not well optimised; the original code is several times faster and has all features, so hopefully someone will port it also.

The latest Lightworks V14.1 beta now has CineForm as an option for transcoding and exporting.

Re: CineForm SDK is now open source

This is very good news. Selling cineform to gopro was a very big mistake. I hope some of the tools will also be available. Particularly the ability to multiplex and demultiplex 3d streams. I would also like to be able have a container wich supports cineform with 5.1 audio. As far as I am aware the avi and mov containers only support stereo with cineform.

Why do you think so? AFAIK there is no restriction of audio based on video. If some programs do impose such limitations they must be mad.

Re: CineForm SDK is now open source

I think this is a limitation of many software implementations. Premiere cs6 has no option for the ciniform avi or mov and vegas crashes with avi and exports as 6 seperate streams in mov format.

But not likely any time soon, as it would appear:

Re: CineForm SDK is now open source

It is a interesting response.
"On that note, the code quality of the Cineform SDK and the fact that it doesn't present a clear and usable interface for clean integration (basically, its not meant to be a re-usable library) mean that any such attempts would require a *significant* effort to meet the FFmpeg guidelines."

See the odd thing is the CineForm SDK was designed to be a library to integrate the codec into third party video tools, has it has be now for over 10 years. It actually predates FFMpeg. Yes is wasn't designed with FFmpeg guidelines, that would be have hard to plan for. ;)

Re: CineForm SDK is now open source

I now using VirtualDub-FilterMod almost daily, as it has native deep-color support for CineForm and MOV I/O, so it is an excellent companion to Adobe tools which way prefer MOV (their AVI support in 8-bit only.)
