cs4 impossible to edit hdv in mpeg format, extremely slow
just got cs4 and it’s easy to work with sd footage…however i now have to edit an hd project, the footage has been converted to mpeg for easier editing but it’s slow as hell. i can’t even get decent playback unless i render any clip with alterations (ie. slow mo, color) like i can with sd footage. project settings are hdv 1080 60i, footage is:
type: Movie
Video: 29.97 fps, 1440 x 1080 (1.3333)
audio: 4800hz – 32-bit Float- Stereocomputer specs:
xp pro 32 bit i think
xeon dual core 3.0 ghz
4 gb ram, only 2.6 gets used out of that cuz it’s xp
raid 0
ati 2600 hd xpi can’t work like this, its going to take me 100 hours to do a project that should only take 35 hours. what the hell can i do? it’s another frustrating premiere experience, i hate this software but need to do this project on it.

I feel your frustration man, I’m used to it now but I remember feeling the same way when I started editing HD.
SD goes so fast compared to HD. I do have windows Vista though and I run 64bit. I have a 2.6G Dual core with 4g’s Ram and it still doesnt play perfectly. I does however get better after you’ve played the project several times though.
I’ve heard that running CS4 with a high performance Mac is even worse, don’t know if that’s true.

i’m going to see what i can do with an upgrade, maybe xp 64 and clean out all my hard drives and see how it goes. but it’s too slow for me to do anything, it will take me 5 times longer to edit a project and it’s not going to pay 5x as much so im not sure what the hell to do. just want to edit at the very least, the same speed as i’m used to. hd sucks!

I’ve cut projects in DV (captured in DV, recorded in HDV) and then at the end offlined the clips and recaptured the HDV recording, that’ll speed up a slow system editing, but it means you capture in RT twice.

sounds like a work around, how exactly do you do this process? I’m working with 4 files that are large mpeg format. ie. 4 – 1 hour mpeg files. I just chop it up from that, do I need to do an EDL to sync all the time codes up so it set its up on the recapture as an HD project?

In the case that you have got the HD files first I would probably send the large originals to AME via the Add button in AME and set the export to DV (NTSC wide?) – when all are in and set to DV export I’d hit Start Queue.
Then in PPro I’d make a new Seq in DV NTSC (wide i’m assuming). Go back to the original edit you made in previous seq select all edits, go to new DV seq and paste. Then in the Project panel I’d select all the clips (HDV ones) and right click to select the unlink.
Keep them on the hard drive, DO NOT DELETE THEM!
Now the clips are offline, Select them one at a time and this time right click and select replace footage… find the corresponding DV clips for each once the BG rendering from AME is finished. The DV seq should allow you to keep your editing in “DV world” and be as fast as you remember.When your edit is done, select all the edited clips in the DV timeline and paste them into the correct HD/HDV one, then go and repeat the unlink and replace footage… to reconnect the HD clips, all the edits should stay in place.

Most MPEG formats use interframe compression (sometimes called Temporal compression, or GOPs) Basically, instead of compressing each frame, groups of frames are compressed together. They are processer intensive and in my experience give PPro CS4 a very hard time. I’d convert the raw footage to uncomressed HD files or a format that doesn’t use interframe compression. I may be wrong, but something with M-JPEG compression would work if you don’t want to do uncompressed. Also, I’ve had problems properly converting MPEG’s to uncompressed formats in Adobe Media Encoder… try After Effects, Quicktime Pro or something else if available.

I know I sound like a fanboy, but a Matrox (RTX2 or Axio LE) card will bring the responsiveness, real time filters, fast rendering & export, and capture screen support you are used to in SD projects to HDV projects in Premiere. I’d hate to get along without them when editing HD (I have one of each). Note that not all PCs are compatable with these cards. Check Matrox’s website for certified configurations.

thanks, I might have to invest in one. I’ve been working on premiere for 5 years now and would like to have a machine that can haul ass and keep up with me. Cheers!

You could also try CineForm. They make an excellent intermediate editing codec.
I’m not sure what you meant by “convert it to MPEG for easy editing” as MPEG is typically pretty stressful on smaller systems…lots of proc power necesary.
Did it start as something other than HDV?

Is this a form of using proxy files to edit? Where can I find out how to use proxy files in Premiere?
