PS: Looks like you need a newer BD player that supports PROFILE 1.3 to play BD-RE.

I have vaio FZ21,now old model,but BD burner is same as in FZ31.It come with burning BD software,but I bought Nero8 and use it for burning discs.

I have no problems with BD-re,maybe because I use vaio for playback too connected via hdmi to my 40" bravia.

If you plan to use Nero8 always set max speed for burning,not automatic as default,because Nero choose 1X speed instead of 2X and burning time in 1x of 25GB BD is about 3 hours.

I moved all my photo/video archives to blu-ray discs.

It burn slow,but read speed is cool.

Using QUAD core should give you performance you need for smooth playback of 1920x1080 in the Source window. It seems you guys have confirmed this.

With Vegas, Timeline performance I've found to less reliable even for FullHD MPEG-2, so I'm not surprised it works the same way for AVCHD.

What I'm interested in how 1920x1080 AVCHD in Vegas 8 works when you CC one clip. Then CC another and perform 5-second dissolve between. Now with no rendering, how do each of these situations play back? I'll bet CC drops fame-rate about in half and the dissolve drops it to 0fps.

PS1: 1920x1080 is 133% more than 1440x1080. Your 60% is going to get very very close to 100% useage -- which is why realtime FX at 30fps is very likely going to be impossible.

PS2: How does Pinnacle play back from the TIMELINE? Is it perfectly smooth?

Using Vegas 8 Pro on my q6600, I played back my SR11 footage with 5.1 sound and it hovers around 20fps on preview auto. Adding a CC drops it to 8fps. However doing a cross dissolve between 2 clips is doesn't drop it much, maybe 1 more fps?

Very interesting. I wonder why? Is it possible the avchd codec is written for only 2 threads (which run on only 2 cores) so that when the second stream comes along -- it gets a pair of unused cores for itself?

Can you monitor all four cores to see what's happening before and during and after the dissolve?

Kim Fong June 28th, 2008 12:22 PM

Well all four cores were running at 90+% for the preview to run at 8fps with CC on both clips. During the crossover fading, it dropped to about 6pfs on average. I was only doing a 2sec crossfade between the 2 clips.

Trying something different, I placed the 2nd clip as a 50% transparent layer above the first, both with CC. This time the playback hovers around 4fps.

That seems to mean to get 6fps to 30fps -- one needs 6 times more computer power. Wow!

No wonder Canopus says AVCHD cannot be edited in realtime with today's computers.

With a Mac laptop I can do about 6 streams of HDV overlayed -- like your second test.

Ken Ross June 28th, 2008 08:12 PM

You can also get many overlayed HDV streams on Caonpus with a PC. HDV is simply less compressed and much easier for today's computers...no arguments there.

Jeff Baker July 3rd, 2008 12:31 PM

We went with the canon HV30 instead of the HF10 because of the codec issues and editing. But we are adding a hard drive recorder into the mix in order to make capturing faster. But we need fast turn around. You would think recoding to flash would mean fast turnaround... but not if you need to edit it. Not yet anyway.

What updates? I thought Vegas 8 already edited AVCHD.

Let us know your results.

PS: Sony claims to edit AVCHD just like you edit MPEG-2 takes 8X more compute power.

I use MainConcept's Mpeg Pro HD to edit AVCHD natively in Premiere. No conversion process is required, just import the files like any other and drop them in any timeline.

How's the workspeed, Douglas? Can you work in realtime and does premiere need to render to get a preview?
Also, do you work with a quadcore?

Do you have to buy MainConcept's Mpeg Pro HD?

Can you export AVCHD from Premiere timeline -- or Encore to red-laser?

What about on a Mac?

And, I too want to know performance as I would expect even with a Quad cuts-only would be maximum.

Jurij Turnsek September 17th, 2008 01:09 PM

Hello,

I'm deciding on buying a laptop that would handle AVCHD playback (24mbs from HF11 too) and editing...

right now, I don't own a AVCHD cam, but I am planning to buy HF11 or something similar in the future...

I am torn between two options:

a 14.1"
14.1" WXGA (1440*900) BrightView LCD
• Intel Core 2 Duo T7700 2.4 Ghz 4 MB
• 2 GB DDR2-RAM SO-DIMM
• 160 GB HDD SATA 5400rpm
• Double Layer DVD+/-RW LS
• ATI RADEON X2300 PCI-express

and 17"
Procesor: Intel Core 2 Duo P8600 (2.4GHz) 1066MHz FSB
Vezje: Mobile Intel PM45 Express Chipset with ICHM
Pomnilnik 4096MB DDRII 800MHZ (ni proste reže)
Trdi disk 250GB SMART SATA 5400rpm
Optična enota: Blu-ray ROM DVD+/-RW SuperMulti DL Drive
Grafika: ATI Mobility Radeon HD 3430 256MB
Vgrajena VGA kamera
Zaslon 17.0" TFT 1440x900 WXGA+ Bright View

Najbolj?e cene za HP prenosnik 6830S (KU425), Core 2 Duo 2.4, 4GB, 250GB, ATI HD3430, 17" - Ceneje.si

If I went for 14.1 I would buy a 24" LCD later and I'd have nice portability.

If I went for 17 I'd get more RAM and better grafics and a Blu-ray ROM... BD, however, is not a factor, because a ROM drive is as good as nothing, I'd need a BD-RE drive, which I plan to have externaly if even... But the portability is a lot smaller - I have a 17 HP Pavillion right now and I don't like to carry it around, although this one is 3kg, which is pretty good.

Now I'd like to know if the 14.1 has the ports neccessary to connect it to an external monitor and if it has the power i need. (i won't play computer games with either)

Ken Ross September 17th, 2008 05:42 PM

I've got a Sony Vaio, T8300 (2.4 gig) with 3 gigs of ram. It plays back AVCHD very smoothly. I found that if you go below a T8100, playback gets very choppy.

Len Charnoff September 24th, 2008 05:17 PM

In the next 2 weeks I plan on purchasing the Sony SR11.

My 5 year old Windows XP 1 gb computer is surely not powerful enough to edit AVCHD.

I purchased Pinnacle Studio 12 and downloaded the Corel VideoStudio 12 Pro.


I know just enough to be dangerous. I'm looking at several HP's Quads and one Gateway Quad.

Although money is always an issue I would pay for the extra horsepower if it was necessary to significantly increase the editing speed.

Question:

Is the Intel Quad more advantageous then the AMD?

Any recommendations on the graphics card. I don't intend to do any gaming.

Tnx.

Erik Phairas September 25th, 2008 08:12 AM

I bought a gateway DX4710-UB002A computer, completely off the shelf at frys.

Q6600
64bit vista
ATI radeon 3650
6 gig DDR2 dual channel

Anyway running Vegas 9 platinum pro and using a SR11 seems to work good enough. Seems if I let the machine think a while after changing something I can even watch the preview at full res at full frame rate. But most of the time it's a bit choppy. Set to auto the frame rate is just fine. I run dual monitors too. I edit in native AVCHD.

Set to auto the preview resolution drops but it's plenty clear enough to see how the video will turn out. I am waiting for the true Vegas 9 Pro to come out (whenever that is) so we get true 64bit operating system support. Can't wait to use all 6 gigs of ram and all 4 cores to full potential.

You can see an example of the native AVCHD playing at full res dual monitors in the vid.
