How to proxy edit HD(V)?
This is one of the most touted features- but I cant seem to find it – how do I enable this?
I have JVC HD100, I downloaded the presets, and the 720/30p playback is jerky – so I was trying to do an offline/proxy edit (edit using lower quality proxy files) to work faster…(I dont want to spend $500 on AspectHD)
searched here.. and also the help file… there doesnt seem to be any direct reference to it…
thanks

HD Proxy editing
Save disk space and boost rendering speed with full-featured editing of low-bandwidth fi les. With proxy editing, progress on your high-resolution projects can continue even when you are working away from high-end, video-optimized machines. Low-bandwidth proxy files allow HD and SD projects to be edited on laptops and other general-purpose machines, giving full real-time features and performance without overwhelming the hard drive or the CPU. A proxy file may be used whether the master clip is online or offl ine, allowing for a choice in scaling the workfl ow and system performance while you edit. When the master clip is offl ine, you can later re-link the master to the proxy or recaptured at full resolution -

The bitrate of the HDV format you mention is the same as regular DV. If it’s not playing smoothly then possibly your project is setup to some other format.
What are the specs of the system you are using including drive types?

I have a HP Media Center PC:
P4 3.2GHz Hyper Thread
3GB RAM (was 1GB, added 2GB more, no difference 🙁
250GB HDD (donno the RPM)
Windows XP Media Center Edition
HP f1405 19″ LCDProject Preset – I was using HDV 720/30p, but since Adobe released an HD100 update 2 weeks back, I tried it, it did make a bit of difference in the m2t playback. But it still jumps, jerks at some points (and CPU load increases to 75-80%)
So I was hoping to do a low-res edit, and export to High res in last step.

You have two problems 1. your system is slightly underpowered for HDV, 2. It appears you only have one harddrive, you need at least 2 Harddrives, one for the OS and Apps, the other for video related tasks to have proper throughput.

The feature you are quoting did not make it into the final release much to many people’s surprise. Including mine.

What is the minimum requirement for HDV? Isn’t it that the maximum RAM an application can use is 2GB? What will you do to make a system like his HDV friendly? Is his processor not fast enough?

The minimum requirement for HDV without using Cineform products is listed as 3.4GHz and 2GB RAM. It is possible to get Premiere Pro to use up to 3GB with a switch but that is really only of value when you have 4GB not 3GB. Remember that Windows takes much of 1GB anyway, and you will often want to open AE or Photoshop even if only temporarily.
The best way to make a system HDV friendly without Cineform is to get a dual core processor, or two processors.
Since I am Cineform’s biggest fan, I am amused at the lengths that people will go to avoid getting better quality and faster editing speeds.

>the lengths that people will go to avoid getting better quality and faster editing speeds.< Hi Steven: I agree the cineform is a good app, but the extra horsepower payw off in other places, Particularly if you are using something like AFX, Boris and/or 3D apps, also the dual core processors tend to run cooler than the P-IVs

Oh, I agree, and I am getting a new PC built around the new Conroe chip as soon as the guy who is building my new system gets them in. But in my opinion, anyone who edits HDV using Premiere Pro without Aspect HD is crazy. Maybe just a little crazy in the case of people with fantastic new systems. But crazy nonetheless.
Not stupid. Maybe not even ignorant. They just have their priorities mixed up. The value of editing using wavelets instead of what Premiere Pro does to a native M2T is pretty well established. And the realtime effects are a huge timesaver. But hey, I am Cineform’s biggest unpaid cheerleader, so take that for what it is worth.

Hi Steve…
So PPro does run ok with the 3gb switch?
I’ve been wondering abot that…

This is secondhand information. But reliable enough that my new system will have 4GB of expensive RAM.
