are there any reason NOT to buy a 5D?

I've been using compressor for several years now. But my approach is a little different and more complicated but it avoids artifacts. Basically I don't convert the final edited video as a whole. Rather I flatten any effects sequences, media manage the project, batch convert each final clip with compressor, reconnect the media in a 24P timeline and finally put it all back together. You're converting the same amount of material because the project is media-managed to only include the footage you need for the edit and by doing it this way it prevents any cross-contamination of one clip into the next. But this approach isn't perfect and can be a head-ache for a complicated edited piece like say a heavy effects based music video. For narrative work where most of your cuts are just that straight cuts it works well.

When you get some examples up please post. It's not the cross contamination of clips, more-like the artifacts in conversion footage. also, please post your method if it's any different than the other FCP to Compressor Workflows.




Not evidence just what I got to show. Don't hate the messenger - that's why I've got.

I mean it in a good way. People test, report results, that's what we need.

ANd no joke it really is a mac. I've been really surprised with how good the machine runs. And I was able to connect an ATA DVD burner from an old machine and use a PCI-X RAID card as well because PC motherboards maintain the older connections that Apple always decides to drop. The Psystar is right there with our Quad 2.6 Mac Pro speed wise and it cost as much as a mac mini. It's not my fault Apple refuses to make a smaller desktop and leaves everyone stranded with the imac or shelling out $2600 for the Pro.

I've had a "Hackintosh" for two years now. 3.6Ghz Machine that still crushes newer systems, naturally, Custom Built. I know all about Psystar and Hackintoshes. There's a massive thread here on DVXuser about it. Plan on adding a Sixteen Core system in the next month revolving around i7 Archtecture, same deal.

Not sure I would ever actually recommend a Hacktinosh for serious work but it's worked out. Mostly, if the system ever has something wrong with it you may be in trouble. Second, if Apple ever decided to ham string the next update your install will flub, and you're screwed unless you know Console commands and have a general understanding of programming language.

Incompatibility with component updates if you ever decide to update hardware, etc etc.

I built my own from the ground up, I'd never do it for anyone else.

That 780.00 box you got is probably a Q6600 on a standard Lg775 Board munchin' on DDR2-600... maybe 800? Dual-Channel PNY Dimms?

Psystar got sued by the way, I'm surprised they're still around though.
 
heat issues ? cmos overheating? cant film for 30 minutes in a row without heat problems? professionals buying a second unit so they can continue shooting while the first one cools down ?

I can film without any of these problems with the GH1 :Drogar-Smoke(DBG):

Thanks.

Please do a time test of 30P to 24P including length of project, output resolution (hopefully we're talking full resolution, as that's the most efficient way to output even for lower resolutions.), and rendering time for project length. Be sure to include processing horsepower at your disposal, etc then report back.

Painless, efficient and simple are all subjective terms. Please make the facts known, we already know the opinions.

Just tried 1 minute of converted video on my old office system (q6600 XP X64) took ~25 minutes using twixter.

We have an i7 that can convert 1 minute of video in approximately 8 minutes. Probably less, I can't get to it right now.. That's 60 minutes of video converted to 24p in about 8 hours.

Output is 1080p, which is then archived on the server and finally converted to delivery.

These numbers are estimates, based on a test set of short conversions.

Twixtor is quick. Not bad at all.

So far Twixtor seems to be the fastest. Can you post method and an example to go along with so we can start a full on comparison?

Thanks Daniel.

Are you on a Server Class Nehalem processor as far as the i7 goes? I'm having trouble deciding between server class or desktop specifically because of a price-power thing.

I'd also like to get away from XP and sit on an MS X64 Platform but RED support isn't really there outside of more expensive solutions... oi.

Oh yeah, filthrich, mostly for RED and VFX processing, especially during farming.

Is that a bad thing? I know nothing about PC internals.

By no means a bad thing at all. Depending on the stepping (revision) of Q6600 it could be an incredible thing.

It's OLD architecture by computing standards, but those are standards that change every three to six months. My current desktop is built around a hand-picked Q6600 G0 Stepping Processor that runs at a pretty low temp for what it is (stacked cores instead of true quad). Think, if I remember right, it's about 72 TDP max?

Because of that, with proper cooling you can clock the sob super-high. The G0 Revision/Stepping in general could see an easy 4GHZ OC on Liquid (water cooling).

Mines is on high-end air (expensive-ass fan) and running at a stable 3.6Ghz constantly. That's a one-hundred percent stock "overclock" from factory rating, which still means it'll burn a newer 45nm (Nehalem/i7) processor as far as raw power goes.

Gets beat when you reach bottle necks like transfer rates in memory, but again for what it is and the cost it's the perfect Farm Brain. If you had a source for hand-picked processors or scrubbed enthusiast wastelands for G0's, you could probably build an incredible farm to QMaster or distribute processes sans anything much more expensive than a Gigabyte Ethernet network and a few extra throw-away computer parts.


This is why I'm always sick, by the way.
 
Great Thread, but stop it guys you're scaring me,
we were gonna buy a 5DII , boo hoo, so are we now thinking GH1?
Or there reasons"Why i should'nt buy a GH1 as well, oops maybe that's thread jacking , sorry lol
Cheers

I've got an identical setup, however I switched my settings back to its default due to some random crashes. What forum do you go on for overclocking? Do you have any guides/log settings of your setup?
 
Look what I have done. Psystar!

Kholi the Psystar is Q8300: Gigabyte motherboard and Intel processors (Q8300) 1.33ghz FSB with 4GB 800mhz RAM & EVGA Nvidia 9400GT all in a basic PC box. The EFI they use is all the hacking required which means none for the buyer. Just push power and it works. Everything is installed and ready to go. And with the restore disc you can reinstall the EFI program and then reinstall Leopard if you brick your machine by installing an Apple update that shuts you out.

I'd post examples of my 24P conversion but I've only used this process with 60i video I've converted to 24P. I just thought the artifacts you were talking about were the "ghosting" of 1 clip into the next that happens. Processing the clips individually avoids this. I'd post the clip I just did but it was shot a long time ago and I have no idea what the shutter speed was so that would be counter-productive. I'd need to just shoot new footage with a 1/50th shutter and then do the compressor conversion. But if you're seeing artifacts with compressor besides the ghosting my approach wouldn't change that.

In the end I'm feeling pretty confident about 24P coming natively to the 5D sooner rather than later. So I don't know how much time is worth investing in all of this. Besides it was easy to see the difference in my footage when I converted from 60i to 24P but to my eyes 30P to 24P isn't dramatically different. It's more of a necessary evil if you have to deliver 24P or more likely 25P for distribution. Purely my opinion, however. I know people have strong feelings about 24P.
 
I did a little search, here's a sum up. The ranking is from fastest to slowest, the first numbers indicate the ratio of render time to footage length:

(6:1) 3 minutes of interview compress/convert to 24p in about 18 minutes on an 8 core.
(If you have a quad core or 8 core, it'll need to be configured in qmaster if you want to take advantage of all the cores.)

(8:1) 8 minutes for 1 minute of video on an i7 with twixter .

(14:1) 1 1/2 hours for a 9 minute clip on an 8 core mac and Compressor 3
(If you have a quad core or 8 core, it'll need to be configured in qmaster if you want to take advantage of all the cores.)

(25:1) 25 minutes for 1 minute of converted video on an old office system (q6600 XP X64) using twixter.

(46:1) 46 min. for 1 min. prores 30p clip to prores 25p. "best" motion compensation in Compressor. MacBookPro 2.4ghz

(55:1) 20 min. for a 22 sec. clip (8 core). (Compressor?)

(63:1) 26 minutes to convert a 25 second 5D H.264 raw clip to 24P and Pro-Res using compressor with the best rate conversion setting. With a quad 2.5 hackintosh, just bought for $780 (psystar).

(95:1) 35 min. for a 22 sec. clip (recent macbook pro). (Compressor?)

(96:1) 8 hours for a 5 minute clip in After Effects using Twixtor 30p to 25p AND Color Finesse, AND resized to PAL on a Core2 Duo E6600 PC

(130:1) 1 Hour to process 27 Seconds of 30P to 24P in After Effect's Pixel Blend on a Octo-Core (8) Mac-Pro, 12GB of Memory.

(300:1) 2 1/2 hours for 30 seconds of 30p into 25p using timewarp in AE. On an older g5 dual 2Ghz

A+ and bookmarked
 
I have been watching hours and hours of 5D video. Because my wife is gone and my kids are asleep. I have not seen 1 second of narrative footage anywhere. Not on Vimeo or Youtube.

And can you even move the damn the camera? Jello is so abundant I'm finding it hard to watch a lot it. I'm gonna have to wait to see what they do about that.

OK, watched them all. Lots of talent & big fun:thumbup:. But you also see that the camera doesn't make a movie on its own...
