Blu-ray Copy not utilizing cpu to 100%

[tc3racr6]

Hi all,

I've scanned the forums and can not quite answer my question.

During blu-ray compression, dvdfab is not utilizing my cpu at 100%. It will fluctuate between ~75-90%. My computer specs are listed below. I have lightning recoding enabled. My HDD does not seem to be pegged. All GPU acceleration is turned off. I can't seem to figure out what the bottleneck in my system is.

Any help would be appreciated. Ive pasted a screen shot to show my hardware usage.

Computer Specs:
AMD Phenom II x6 1100t (OC'd to 3.6 GHz)
COOLER MASTER Hyper N 520
Thermaltake V3 Black Edition (Case)
HIS H685FN1GD Radeon HD 6850 1GB
BIOSTAR TA990FXE AM3+ AMD 990FX
OCZ ModXStream Pro 700W Modular
G.SKILL Ripjaws X Series 8GB (2 x 4GB)
LITE-ON Black Blu-ray Burner IHBS112-04

cpu 100%

tc3racr6,

Try turnning off "Lightning Recoding" and hit the green check mark on top right conner and check to see if "Enable Turbo CPU for maximum cpu usage" is checked! It will be under DVD/BLU-RAY, convert!

If you read all over the forum you'll see "Lightning Recoding" causes more problems than it helps!

Your time in M/B's (6.43) is very slow, I have an Intel i5 2500K, Quard Core O/C'ed at 3.75 and my M/B's run up around 17's to 19's!, but my CPU doesn't max out eighter!(75%-85%) Never had a blu-ray over 35min's!

Give that a try and see what happens, its wroth a try! Maybe someone else will chime in and give some expert advice!

I was looking at your ram usage 42%, I have only 8GB too! Consair Vengence 2x4(1600) and it stays around 20% to 28%, with your set-up I would think it would be flying! Maybe more ram for your 6 core CPU! Just guessing!, but I would try it without "Lightning Recoding" enabled!

Lightning Recoding

I have found that lightning recoding (LR) really speeds up my compressions. Going from 2.5+ hours down to roughly 80 min. I have had no quality issues with LR enabled, no artifacts, skipping, data loss, etc. I am pretty sure I have "Enable Turbo CPU for maximum cpu usage" checked.

I will test your method tonight and post my results.

I have disabled lightning recoding, ram settings are max, turbo cpu is checked, also I changed my quality setting to fast/normal quality. I seem to be getting higher CPU usage, but my compression times are still relatively the same. Also, why has my video rencode bitrate change? Is that due to the high vs. low quality setting? I have included a new screenshot. Below is my most recent internal logs also:

Dang. I would kill to have 8 MB/s !!

Also, why has my video rencode bitrate change? Is that due to the high vs. low quality setting?

That would have more to do with the length of each movie + type of Audio you are using. You are using 2 different movies, they may have 2 different audio codecs where one takes up more bytes. So now the video needs to be compressed more to reach the same total. Remember that when compressing a video to fit on a 25GB disc the software is shooting for a specific number of total bytes. So if the audio takes up 10% of that total then the video needs to compress down to 90% of that total. If the audio takes up 5% of the total then the video can use up to 95% of the total.
