FCP should do Real Time in ucompressed HD right? Well it doesn’t, why?

[Steve Connor]

HD playback is real time in FCP, there must be a problem with your settings somewhere, probably in the codec, can you list your exact settings for the Quicktime file you created, I think you would need to select the Apple Uncompressed Codec rather than no compression in orderto get the RT.

[Levan Bakhia] “This is my workflow. I shoot on film, I transfered from film to targa sequence in uncompressed HD 8 bit. Then I made a quicktime file in quicktime with this targa sequence, I chose no compression at all when I edit it in FCP it requires render on everything I do except for just cutting the matterial. Even the simple transition between two track need rendering.”

It sounds like you’re not working in a standard FCP codec or something. Did you basically create an uncompressed HD quicktime using the Lossless (Animation codec) setting? If so, then yes, you’ll need to render everything.

I’ve worked with 8 and 10bit 720p and get normal RT performance running Fibre Channel arrays. For 10bit HDCAM you need the absolute fastest drives running to get RT performance and you need to work in a native FCP setup.

In this workflow there is no RealTime anything.
Apple has never said that you Uncompressed HD in real time in anything other than the apple or panasonic compression format- Avid and others share the same philosophy.

And the RT that Apple speaks about is in 720p, not a 1080 timeline with no compression to the video at all. In reality it actually surprises me that the a single scsi array can handle the data rate for 1080p video using “none” for compression (something near 320mgs a second or nearly the data stream of Dual Link)

I wouldn’t agree with that – until MC Adrenaline HD was released, DS was the only HD enabled product and with the Nitris configuration you can easily do 2 streams of HD 10 bit uncompressed – each layer with a dve and colour correction applied.

Just to be clear…

[Paul Ingvarsson] “and with the Nitris configuration you can easily do 2 streams of HD 10 bit uncompressed – each layer with a dve and colour correction applied.”

And what is the price of the AVID DS/HD with the Nitris configuration? It had better do the dual layers with DVE and Color Correction for the price of it.

But that does not equal better picture quality. The output of my Kona 2 is equal to that of the AVID DS/HD. Do I need to render more? You bet. Do I have a higher profit margin? You bet!

I am torn between Apple/FCP and the Matrox Axio. Saw a demo on Axio,
the demo guy was doing 3 layers and 2 graphics in real time with
uncompressed HD footage. An entire Matrox HD set-up runs $22,000-$30,000
A comparable Apple set-up – a bit less. In the end I am leaning Apple
because of it’s acceptablity in the Advertising industry, I would like to have
that level of compatibility. So the original question… Does FCP do real-time
at any level Uncompressed HD?? I have read all the specs but have not seen any
demos with FCP & uncompressed HD.
Matrox seems great but if no one has heard of it
and does not understand it – even if it might have a real-time edge….

If you use the Apple or third Party uncompressed codecs, you get real time playback, some configurations will give you RT colour correction in 8 bit uncompressed.

We get round this by Offlining using the DVCPro HD codec which gives you loads of real time effects and multistream playback and is almost identical visually to uncompressed. Then when the edit is finished we recapture to uncompressed and render transitions and effects.

99% of the time the client doesn’t even spot the difference in quality!

Hello Steve,
So after client approval you re-digitize the footage??
How long of a show are we talking about??
Thanks

Paul the original quote Apple has never said that you Uncompressed HD in real time in anything other than the apple or panasonic compression format- Avid and others share the same philosophy.

I said to get real time playback you need to use an Apple or Panasonic codec, –No Nitris system I have ever heard of would play back 2 streams of some “none” compressed HD on any type of machine. To get real time DVE and color correction on any platform you need to use the custom codecs and setting each of the manufacturer supplies— not something random that you choose.

I stand by what I said.

Actually, iQ can play uncompress Targa files natively

Of course iQ is in a different league 🙂
