What preset are you using in Premiere?

Adobe might run some specials on CS5 at NAB – hard to predict – but I doubt they will be substantial.
Are you a heavy CS5 user? Will your workflow take advantage of CS5’s performance enhancements and new features? If so, the time is right… 🙂

[Anthony Hartis] “1) which is the best compression and, 2) how should I prep the files in Photoshop? Use square pixels for monitor viewing, import large files into Premiere, etc.? I just want the sharpest image possible, like I see it in Photoshop. I know my files are large enough”
In addition to what Vince said – and if your system can handle that – you could do the edit as a 4K sequence and upload it to YouTube as a 4K file that they now support. Granted, very few systems can benefit from 4K playback – most can’t display more than 1080p – yet this way, you ensure the best possible quality YouTube can handle – and YouTube will do the scaling and re-encoding for you, for 1080p and lower resolutions.
From what I’ve seen, high detail 4K videos use 25-30Mbit/s bitrates peaking at 55Mbs – so encode accordingly. Maybe do a short test edit and upload first, to gauge the quality and ease of editing.

[Ann Bens] “Imo its better and easiest way is to set the hdv camera to downconvert and capture it as DV through firewire on CS5 directly.”
I think you’re right that it’s the easiest, and should be possible – e.g. Sony FX1, Z1 and Z5 all support down-conversion on the fly via FireWire/DV.
James did say his camera wouldn’t let him; is it possible his camera doesn’t support on the fly down-conversion?

Is this a Premiere (not AE) issue? (I know this is a Premiere forum – I am just checking to be sure.)
What are your systems specs? (Make/model, CPUs, RAM size, OS version, storage.)
Pr and Ae CS5 do need more RAM than their CS3 counterparts and if your system is low on RAM, they may start running very slow.
Please elaborate on those exploding file sizes – which files are getting bigger – project, cache, media? Is it easily repeatable – e.g. can you create a project with 1-2 clips and repeat the file size expansion every time you do that?

[Hannah Radcliff] “I mean, FCP5 on a PowerPC with 2GB ram and a 128 MB graphics card cut through the footage like butter., and I was in and out in about 15 minutes.
So if that machine can handle it with no drama, seems like my laptop should be more than capable….”
Possibly, Premiere doesn’t like that specific file format or codec, and doesn’t work with it as well as FCP.
If you can bring your project onto a known-good CS5 system, it would help – at least you will know if it’s a general Adobe Premiere issue, or a system-specific issue that you could try digging into.
If you are experiencing playback issues within first 10-20 seconds of a clip, would you be willing to make a short clip available for testing – e.g. upload is somewhere?

“The Matrox folder is gone” – containing presets? I would re-install Matrox utilities first and see if that fixed the problem; if you’d like to investigate this further, Matrox forums or Matrox tech support might be the way to go.

[Keith Moreau] ” I upped my RAM to 24GB and added some SSD for boot and scratch disks and things are at least cosmetically speedy.”
Smoking!
[Keith Moreau] “I have a few days left to decide to keep the Quadro or just use my old but apparently powerful GTX285”
The GTX 285 has almost twice the memory bandwidth of Quadro 4000 (159GB/s vs. 90), half its RAM, similar number of CUDA cores. It also uses more peak power – 204W vs. 142.
The faster memory bandwidth easily explains why GTX 285 is faster in some tests.
If it was up to me, I’d keep the Quadro: about the same performance in Premiere Pro and AME; it’s cooler (literally); should be faster in OpenGL apps, takes one slot rather than two.

[James McLean] “We shot 5 hours of HDV footage.
Our camera wasn’t set on “Down-Convert” (we tried to set it but it wouldn’t let us) so we couldn’t capture it onto our normal editing program (old version of Adobe Premiere Pro, number 7 I think, which only plays DV footage).
So we captured it on Final Cut Pro but that captured it in HDV. So now we need to convert it to DV.”
I think that in-camera down-conversion only works on analog and uncompressed digital (SDI) output but not DV/HDV.
Two options then:
- re-render your footage in FCP or other software (Squeeze, AME, etc.);
- re-capture using a different mechanism: set the camera to down-conversion; connect its S-Video port to a GV ADVC-110 or similar analog-to-DV converter; capture the output of the converter via FireWire into FCP or Pr.

[Rick Diamond] “Actually, I just tried to open another job and the Matrox presets are mysteriously missing. How can I find them?”
Can’t think of a reason it would. Have you tried restarting the system?
