We have a 27 inch we take on the road when we need an computer and can’t bring a tower. So far it’s worked out really well for us.
In my opinion the biggest downfall to editing on the imac is the single Firewire 800 and 4 USB Connections. Does not give you a lot to work with. I have been looking at having OWC add an esata to it, it’s a pretty inexpensive upgrade.

As far as processing power and Ram are concerned you can put way more in an iMac than FCP can currently access so no worries there.
my 2 cents

That’s the correct settings, but it will only create an Alpha Channel where there is no information. So if you have a background layer on you need to disable that first.
AE’s defualt is to show an Alpha as black. Click the little checkerboard looking box underneath your comp preview to show a checkerboard where your alpha is going to exist.
This makes it easier to verify where you alpha lives but has no effect on the render one way or the other.The Animation codec creates huge files. 500MB for 60 seconds sounds pretty reasonable.

You just need to choose a codec that supports Alpha Channels. Animation, PNG, and most image sequences (tiff, psd) would work. If the codec has an option to set to millions of colors+ then you know it supports an alpha. The + is the Alpha.

Try Right Click or CMMD Click and select open in viewer. That will get you access to the position property.

Oops. Read to fast. Those are the same settings you already found.
So what you want to know is how to create a [4:2:0 GOP of 15] using the
GOP settings listed. Hopefully someone smarter than me on compression issues can chime in and answer that.Regardless, AE does a poor job as a compression tool. Rendering lossless out of AE and taking it into Media encoder is going to give you a cleaner final output.

Render lossless from AE and then take it into Adobe Media Encoder.
You should find all of the appropriate GOP settings under video>GOP Settings.-Andy George

Hi Huffy,
The footage your working with uses a non-square pixel aspect ratio. Unlike FCP Quicktime player will not handle a non-square pixel. So the key to getting the aspect ratio to appear correct is to convert it to a square pixel aspect ratio.
Your 1440×1080 footage in square pixels works out to 1920×1080. If you want to make it smaller than that you can choose from any proportional size like 1280×720, 960×540, 640×360 ect.
H.264 is a good choice for a codec if your not intending to edit these low-rez versions.
At 640×360 you could get away with some pretty small rates. I would start at about 600-700kbps and move up from there until your happy with the picture vs size. At 960×540 I would start at around 1200kbps

Michael,
Thanks for pointing that out. I had some bad information there.

Good to know you can download that player. Learn something everyday.
The h.264 backup sounds like a good plan. Im guessing the h.264 will be roughly 100-150Mbps smaller, so it’s a pretty large data rate savings. I think you would be hard pressed to tell the difference.

The speed of your hard drive is more of a factor than CPU and RAM when playing large HD movies. Placing the movie on the mini’s internal drive should give you the fastest playback speed if there is room for it.
A few things to consider-
Prores is Final Cut only so FCP would need to be installed on the mini.
Prores (HQ) is a 10bit codec. Without the (HQ) it’s an 8bit codec. Unless you shot on a very high end system like a Red Camera or Film, your not gaining anything by using the (HQ) version. It’s just making the file larger. The 8bit version will be much smaller and the quality will be the same.
If this task were handed to me I would create a lossles H.264 for delivery.
(put it in compressor and set Data rate to automatic/better)
The file size will be drastically reduced. Acquisition and delivery are where this codec does a great job.-Andy George
