Prores equivalent?

[Shane Ross]

Exporting to DNxHD to take to a place to convert to ProRes is an OK idea. There is an issue with gamma shift when going from DNxHD to ProRes, so whoever does the converting needs to watch out for that.

Thanks Shane,
well, most likely I am doing converting – can you refer me to any thread/website where I can get better knowledge of this gamma shift problem (or better step by step what should I do). I guess I can convert it using programs comming with Apple FCP version 6, but is there any other 3-rd party application suitable for this?

Don’t know if I know the solution…or if there’s articles out there on it. I did find this:

https://www.drastic.tv/index.php?option=com_content&view=article&id=202:prores-colour-shifts-in-post-production&catid=59&Itemid=94

But it’s always something that I’ve had to fix when I brought it into another NLE or if the encoder allowed for it.

Other than FCP 6, what options do you have? Episode by Telestream? Squeeze (on mac), Compressor….?

Compressor, MPEG Streamclip (if this is any help)…

From Pr, I usually just export 10bit Uncompressed YUV 422. I have Cinec on the PC which can then make ProRes files. Uncompressed is universal and YUV means no gamma shift.

I can also bring the uncompressed into Compressor on my old MacPro which is still in the system.

Premiere Pro CC also offers GoPro Cineform on both PC and Mac. This codec is also very similar to ProRes and Avid DNX. It has both YUV and RGB settings.

Don’t be fooled by the GoPro name. This codec is not the same highly compressed H.264 codec used by their cameras.

thanks guys, this is a good hint!

Had a similar situation. Edited a film in Sony Vegas Pro 12. Needed ProRes 422 HQ.

So….

If hard drive space isn’t an issue…render in UNCOMPRESSES QUICKTIME.
My 80 minute film was 700 GB uncompressed.
I ran that through MPEG Streamclip and the ProRes 422 HQ file looks GREAT. No color shifting, either.

Of course, you’ll want plenty of space on a hard drive.

Hi everyone,

I will be switching back from Mac to PC very soon due to several reasons. Mostly because of the Cuda based and Perfomance ones. The only thing I will be missing is the Prores Codec. I read about the GoPro Codec here and I know that this Codec is TCFKAC (the Codec formerly known as Cineform) – that Codec was even superior then, when Prores was invented and I used it alot. It used to cost 500-1000$ per licence if I remember correctly. But it was limited to 1080p the time I switched to Mac.

1. Does anyone know if this is Cineform and is it still available in After effects and Premiere CC ?
1.a. Is it capable of 4K ?
2. Is there any other performant Codec you can advise (besides uncompressed of course) , when switching back to PC ?
3. Does the Prores Decoder for Windows still suck ?

cheers,
David

[David Bhulapatna] “1. Does anyone know if this is Cineform and is it still available in After effects and Premiere CC ? “

Yes, and yes.

[David Bhulapatna] “1.a. Is it capable of 4K ?”

Yes.

[David Bhulapatna] “2. Is there any other performant Codec you can advise (besides uncompressed of course) , when switching back to PC ?”

Premiere Pro also has native support for Avid’s DNxHD/DNxHR.

[David Bhulapatna] “3. Does the Prores Decoder for Windows still suck ?”

No. Adobe has a licensed, native ProRes decoder on Windows now. A QuickTime installation is no longer necessary for reading ProRes files.
