Can Premiere CS6 WIN Export ProRes?

One of the biggest problems I have had in the past Under Premere windows is the inability to export ProRes codec. Can CS6 Export ProRes? Also, can Premiere CS6 work in 24 bit audio or is it still 16 bits only? Thank you.
 
There's no legal path to writing ProRes files on Windows.

Premiere Pro actually conforms audio files to 32 bit floating point for internal use, always has.
 
I never understood the definition of "WRAPPER". What is the difference between CODEC and WRAPPER? Are you saying tha exporting H264 n QUICK TIME MOV is the same as exporting it in AVi or MP4?
 
Cinemartin converts to PreRes but it does not allow me to export PRORES directly from the Premiere Timeline. This means I need to export in Cineform and then convert to ProRes which is a generation loss. Is there no way to export ProRes from the Premiere timeline?
 
Simple, just export to an uncompressed or lossless codec and then transcode to Prores. Why would you need to export using Cineform?

OK, this is complicated, but let me try to explain as best I can....

A movie consists of audio and video. Because uncompressed audio and video are absurdly big, they are usually stored compressed; and to preserve the maximum quality in the smallest file size, the compression is EXTREMELY sophisticated.

Now, the way you compress video is (in real implementation terms) nothing to do with how you compress audio. Video compression is done by a completely different piece of software / hardware from audio compression. So when a movie is recorded, the video data and audio data are handled separately, and each is compressed independently, resulting in a bunch of data for the video, and a separate bunch of data for the audio.

The most mainstream FORMAT today for video compression for end users is H.264. ProRes is another format, used in production. A popular audio FORMAT is AAC; another is MP3; etc.

A CODEC is a piece of software (or software and hardware) which converts from one format to another; e.g. you can use the X264 CODEC to convert uncompressed video to the H.246 FORMAT. When you play back, another CODEC is used to uncompress the video, and another one to uncompress the audio. Note, though, that people often say "codec" when they mean "format".

Now, the easy thing would be do deliver the video and audio in separate files; however this would be a big pain for everyone. So instead, they are bundled together in a container file (or "wrapper"). You can think of this as being like a ZIP file; but an actual ZIP file wouldn't work, because all the video would be first, and all the audio would be after it, which doesn't work at all for streaming. (Unless you want to hear the soundtrack of your movie after watching the pictures.) So a real-life container file cleverly interleaves the video and audio (and alternate audio streams, and subtitles) so that they all play at once. It also includes synchronization information so that the audio can be played exactly in sync with the video.

Container ("wrapper") formats are formats like MP4, MKV, MOV, etc.

It gets very confusing because sometimes container formats also specify a video compression format and an audio compression format. For example, MPEG2 has its own video format, MPEG2 part 2 (which is actually H.262). Also sometimes people talk about a container format when they are trying to talk about a specific video format, and vice versa.

Bottom line, if you have a MOV file, there's no way you can tell from the filename whether your computer can play it, because "MOV" is just a container. You would need to examine the file to see how the video and audio are actually encoded.

And yes, wrapping your H.264 video in a MOV container will produce the same pictures as wrapping it in an MKV container, or MP4 container. However not all possible combinations of wrappers and video/audio streams will work.

Hope this helps....
 
To the thread starter, think of the wrapper as the file format like MOV or AVI but within those formats you can use different codecs. For example AVI can be compressed with different codecs like XVID, DIVX, etc.. so its the same thing with MOV Quicktime files. Within Quicktime you can have DnxHD, ProRes, Sorenson, mpeg, the list really does go on and on...

Premiere running on a MAC can generate ProRes files so if this is one time project where you need prores consider using a MAC to do your conversion or asking a friend to do it. You can render a high quality output file from Premiere and run it back through the MAC to get a prores version. But if you don't want the "generation loss" and want a prores file directly from Premiere you would have to get Premiere running on your MAC (mac version) and re-render it that way. You can probably use a trial version of Premiere for MAC to do this for you.

If all that sounds like a hassle, then you're back to buying a third party convertor program for your PC so you can convert it after the render.
