Converting AVCHD to AVC Intra Crazy?

...and also...I have never used a RAID .

MY main system specs are relatively humble...but a custom built system dedicated to Edit , audio and Graphics

Win 7 - I7 - 24GB RAM - 2x Nvidia GTX Cards.

I believe spreading the sources on various drives is advantageous and necessary considering no RAID. I have always done so. Makes sense to me. Must add - they are organised as well.

Erik, have you seen the suggested drive setup on the Adobe forum, like Shooter's?

This thread isn’t new but it has lots and lots of info.

I have to try spreading out the media across several drives and see if it helps with performance. At home I can do this since I use an external five drive eSata port multiplier RAID0. I’ve used this setup for a few years and it’s pretty fast.

AJA Speed test.
207mbs Write.
236mbs Read.

At the station I have an internal three drive RAID0. No more drive bays left. I still have legacy and other projects that require FCP 7 unfortunately, and splitting up that RAID would be a chore.
 
I just did a conversion of one AVCHD card with 14.64 GB of media on it to AVC-INTRA 100 and the new P2 card is 110.52 GB. Thats huge and way larger than I originally projected. A little under eight times the size of the original AVCHD media card. I used Adobe Media Encoder to do the conversion.

What were the specs on the AVCHD footage? 1080p24? p30? 60i?
 
I found this on Wikipedia:

More over, the AVC-Intra Class 50/100 is now extended to Class 200 and Class 4:4:4. The Class 200 mode extends the bitrate to 226 Mbit / sec for 1080/23,97p, while the Class 4:4:4 extends the possible resolution from 720p to 4K with pixel depths at 10 and 12 bits.

Perhaps that's why it's 8 times larger instead of just 4?
 
Interesting. I can’t pick the quality of AVC-INTRA in Adobe Encoder so not sure what the nitrate is. I need to take a look at a clip inside Premiere to see.
 
I was reading in one of the adobe forums about this and they think this is a bug with CS6 that Adobe is currently working to fix, in the meantime a lot of mac premiere avchd users say that cs5.5 works perfectly...
 
Erik, I just ran a test on a sample of AF-100 files from a card that was about 3GB in size, and the resulting AVC-I folder was 12GB, which seems correct to me (24Mbps vs 100Mbps). Granted this was 1080p24, so perhaps that could be an issue? I am running the latest version of Media Encoder CS6 on Windows 7. I set up a preset to do AVC-100 1080p 23.976 with Render at Maximum Depth and Use Maximum Render Quality both checked.
