Premiere Pro, Lag and Lag everywhere, WHY ! Please aid me in optimizing my System.

[Sibel Zivy]

Davis you know I’d rather cut back on quality than go through that rigorous process of encoding, because some of the clips I have are very long(40mins) and I only need/use a small portion(7min MAX) portion from them.
So I’ll record @ 1/4 less of the base quality and try to optimize my PCto ensure that there isn’t any performance hidden or kept out due to my ignorance.

Here’s my email: qwasiz-ex@hotmail.com

I really can’t thank you enough for what you’ve thought me Davis! Thank you!

You might want to invest on a modern computer.

Also Jeff would you mind explaining the difference between the green and black WD drives, when I view their specs they were very similar, the retail guy said that the black had a longer life span which is why it was more expensive, I do feel deceived, But why is the black better and can I go for a better option ?
I’m starting to think my bottle neck could be the drive..

Thanks Jeff

If I had the $$$ I would.

The reason I’d go through all that encoding is to troubleshoot.
By encoding it properly to an intermediate set of formats, You can identify where the problems are. WIth a proxy in an intermediate, you should play back quickly, but have great quality. If you don’t, we know it’s something in your configuration. Then we check your rendering configs. Start by turning off the more advanced rendering architectures, then turn them back on one at a time, rendering a small work area each time ( 30s would do) and checking for lag times. With a compressed format, the renders take longer because they have to be decompressed, edited, and recompressed. WIth an intermediate format, there’s a lot less “Guessing” in the algorithm, and it’s shorter. My comp is a dinosaur, so any speed bump I can get is gravy. I rent studios to render and farm it when I can on the output side. But rendering previews I do on my own machine. Quality you never sacrifice… …resolution, maybe. Drop out a proxy at a lower resolution and interpret that to your sequence, then try again. But check your specs and configs. Some newer tech and software haven’t been playing well as of late, and you may have fallen prey to those bugs.

Is this a single drive enclosure?

If so… …That may be the problem. USB 2 is limited to 480mbps max and rarely goes above 50 in most enclosures. USB3, while rated at 1.5-5gbps rarely goes above 300mbps on quad core machines with HDD’s (it’s a limit of processing more than the bandwidth). Most HDD’s cannot handle much more than 300mbps because of their mechanical nature. RAID is a technology of combining the speeds of several drives (as well as the space), and they are better to use for video editing than a single drive external for a multitude of reasons. 2 cheaper, smaller space drives can be faster than one bigger drive since the data is written in stripes (across both drives, alternating packets) and twice the data can move in the same amount of time. This also results in fewer writes to each drive, extending the life of the plates. They can reach data rates of 800mbps to 1.3gbps with 2 drives set up to stripe. More drives allows more speed, and more space.
Remember also, with HDD’s your spin is a big part of your speed. 5400 to 7200 is a pretty big jump in speed. But reading an original is what happens in rendering. Using a raid with 2 5400rpm drives (cheaper drives) is better than using a single 7200 at the same space of the combined 2, for speed reasons. Put your originals on their own RAID and you’ll be able to read them faster as well. Reads are usually 12-100mbps for most usb HDD’s. FOr RAID, the device will transfer much faster to several drives. 400mbps-1.5gbps depending on your interface (usb3 will max at about 1.3gbps with 4 drive raid at 5400rpm on each drive; at least that’s been my experience on some newer towers with windows, and 1.2 with mac 8cores).

[Jeff Pulera]

The “Green” drives are all about POWER SAVINGS versus PERFORMANCE of the “Black” drives. Green drives will spin down every chance they get. Just not ever recommended for video editing which needs constant, reliable throughput without interruption.

Ht – I now understand your suggestion to use proxy editing, as you stated your computer is a “dinosaur”. I think most folks on the forum on using something at least from the current decade, so when they have performance issues, we look for solutions other than proxy editing which would be a crutch when perhaps there is a better solution to their issues.

Thanks

Hey Jeff !!! I took your advice and I found this amazing HDD, WD’s Velociraptor, It’s in my Amazon my cart and the 1TB version is on sale @ 193$,Luckily I can barely cough that out with my budget, So would you recommend it or is it way too much power for my application, mind you all I’ll be using is H.264, So what’s your verdict ?

[Jeff Pulera]

I didn’t say to get a Velociraptor…you can get the “WD Caviar Black” for less than half that cost and it will be fine for your needs. Maybe get a 2TB instead and still cost less.

Thanks

I’ll get your recommendation,
the 2TB Caviar Black has better value plus I’ve seen benchmarks, the 70$ difference isn’t really justifiable for the Velociraptor.

Thanks Jeff and god bless !
