HD in after effects (storage, proccesor, etc)

[Steve Roberts]

Get at least 8 GB of RAM.

For storage, read this:

The processor is fine.

The graphics card must be supposrted by Adobe, otherwise it doesn’t matter what you get. Switch OpenGL off until Adobe imp[lements it better.

Thanks my friend for your help but…

How can I manage that amount of Ram ??

As far as I know my After effect just read 2GB of Ram. I will update my windows to XP64 but how the After Effects will read the 8 GB ?

Thanks my friend but..

how do you manage the 8GB of ram in After effects ?

As far as I know the After effects just can read 2GB of ram.
I will update my Windows XP to windows XP64 but this will read the 8GB?

Is it something that I have to set in after effects to read that amount of ram ??

Thanks for your help.

If I understand well

They are talking that for video you will need 120GB per minute ?
I am not sure if that is correct for this .The footage is HD SR 1920×1080 59i 4:4:4.

At your understanding, how much GB do I need per sec ?

[Steve Roberts]

Well … though the format you stated seems to run at 800mb/sec, meaning 100 MB/sec, 6GB/min, 360 GB/hour … I assumed you’d be working with *uncompressed* TIFFs, which would equate to uncompressed video sizes, I’m assuming.

If you want, you can make a TIFF at 1920×1080, check its size, then do the math.

Anybody else, please feel free to correct my figures …

Steve:

I understand your point but if I had the chance of knowing the size of one tiff frame I wound,t be asking help hahaah !!!

I am a little confused because some collegue that works at post production house facilities told me that the size of one tiff frame of HD SR 4:4:4 is 10MB. Hence, it would be just 18GB for one minutes of footage at 30i frame rate.

But I still think that is not as much hard disk space as it would be.

Regars..

Is this the tape format?
https://en.wikipedia.org/wiki/HDCAM_SR
Note that you will receive TIFFs that have been made from this format.

An uncompressed 8-bpc 1920×1080 TIFF (which can be made with AE or PS alone) came out to be 5.9 MB. Maybe your Post person is talking about 10-bpc TIFFs. (10-bit-per-channel)

There’s no such thing as “a TIFF frame of HD SR 4:4:4”. I think we’re talking apples (TIFFs) and oranges (HD SR compressed footage). You will not be working in HD SR format — you will be working in 1920×1080 uncompressed TIFFs, right?

You need to know if they want 8-bpc or 10-bpc TIFFs, at what compression, if any. You must know *exactly* what the post house wants from you, in terms more specific than you’ve given us so far… 🙂

HDCAM SR is 10bit RGB.

Work with Quicktimes/DPX/etc – formats that supports 10bits and your data rate will be 180MB/sec @ 24P.

Work with TIFFs, etc that are 16bit and your data rate will be 60% more, as you say, maybe a little less if you use LZW. No reason to use extra bits as they are not there to begin with. Render at 16bits/float – but store in a 10bit format.

General recommendation is 2gig ram/core – the 8gig ram suggestion is to make the most use of your extra cores for rendering.

Steve:

you are being a big help to my doubts. I appreciate your time you are spending on me.
I am sure that they want a 10 bpc tiff secuence. what I am a bit confused if it is ok for them to recieve from me a 10 bpc tiff secuence to join with the rest of the video that was transfer to HD SR 4:4:4

What I haven’t told you is this… The footage will be capture on film and then it will be transfer to HD SR 4:4:4. They will work ON LIne at that resolution, I will make the effects with tiff secuence of that footage and they will end up delivering the final video with my effects integrated to TV channel in HD SR 1920×1080 59,97i.
That will be the process.
