CPUs for HDV/AVCHD editing

I am starting to put together my system, piece by piece (I am cheap so i wont buy till I find it on sale)
I have read on this forum alot about the i7 920 being the best cpu to get.
As I have spoken to some of the retailers (only one who seem to know what they are talking about)
They have mentioned i7 is last years technology and that video editors
like it because it can be greatly over clocked.
But since its last years news what about the i5 (this years news).
It is less powerful?
I have been told it cant be over clocked, is that a feature Intel purposefully removed since it has the
power and doesnt need to be over clocked?
What about AMD Phenom?

In my opinion it is. The i7-870 is pretty expensive in comparison to the 920. This is of course offset by the mobo price (P55 are a lot cheaper than X58 boards, but more limited in both PCI-e expansion, graphics capabilities and memory capabilities, not to consider Gulftown capabilities).
I still have to see i7-870 benchmark results, but take into consideration that my system, which is based on a i7-920, holds the top position on the http://www.passmark.com/baselines/top.html list with a score of 6055, that my same system running at only 3441 MHz holds rank 9 with a score of 4623 on that same list (see BL# 106949), which leaves all the other systems running at 4000+ MHz in the dust, further consider my top position at the PPBM4 list and I think that I can safely say that I have a pretty decent system and if I were to build a new system today, I would not change anything relevant today, despite that my system is already 6 months old. Maybe a Noctua NH-14 cooler instead of the NH-12 I have, or some SuperMicro disk cages. But that is all.
Look at the results below to see how my system performs in comparison to others, and you may be convinced:
This is at a clock speed of 3441 MHz

AVCHD editing in Final Cut Studio 2 vs. HDV? Which workflow is smoother?

How is AVCHD editing in Final Cut Studio 2 compared to HDV?
I am in the process of buying a new camcorder.
Thinking about the Canon HV30, but I am considering AVCHD and the HG 10 or HF 10.
I just heard that AVCHD is tough to edit... Is this true?
I have a 24" iMac 2.8GHz Extreme Core 2 Duo with 4 Gb RAM, and I wonder if that would be enough horsepower to edit AVCHD. I also have a 1 terabyte Raid for storage.
I love the idea of being able to just transfer over clips rather than Log and Capturing through an entire dv tape, but is the workflow of AVCHD more work in the long run.
I am more concerned with workflow than even picture quality.
I have so far only worked in SD... so any thoughts from people with hands on experience and can give a good comparison of the two workflows would be greatly appreciated.
Thanks!

AVCHD isnt any harder to edit then HDV. We are running the SONY EX1 which is Sold State Camera. You have to use Sony XDCam Transfer software to get it into FCP.
Here is what we found.
AVCHD is a lot faster to ingest (ive found 4x realtime) and because you have to use the Sony XDcam Software for transfers you end up with better Loggin metadata (mostly because its easier at the time of transfer)
AVCHD is more expensive to run currently. With 16GB cards giving you 57 minutes of video they cost about 400 Pounds a card (im in the UK). On the plus side is you can view your footage instantly with a MacBooK Pro using the ExpressCard slot to plugin your solid state card and XDcam Viewer software.
Backup can be done in one of to ways. Use a SONY XDCam deck and store the footage on their XDCam Cartridges (way too expensive option). or use external Hardisk (we use 2 one for storage on location and second for Backup and later on for long term Storage in our Library).
When it comes to HDV we use the HDV-Z1 cameras and the process with the Z1 is just the same as with a consumer Level DV camera. It takes longer to ingest video because its realtime. But once in it runs fine. For backup its already done by the tape and again we store all Footage on Harddisk for long term storage once the project is done with the Tapes as backups. Oh.. and also the tapes are really cheap compared to the Solid state cards.
I have to say i was happy with AVCHD at first because the initial setup was very expensive. BUt once setup the workflow is smoother and faster the HDV tape based system. I do find the quality to be better as well on AVCHD.
I hope that helps

Best editing card for HDV

what is the best editting card on PowerMac G5 that i can work either DV and HDV without lossing any quality especially in HDV
i getting a new PowerMac G5 & gonna use it for editting, i have DV & HDV camcorders , im trying not to loose quality for HDV when capturing
Thank you

None, really. FCP 5 is meant to handle DV and HDV (and DVCPRO HD) over firewire with no loss of quality.
BUT...if you are talking the JVC and 720 24p...then you'll need a capture card. AJA LH or LHe, depending on the model of G5 you have.

Exporting fce4 avchd edited movie to dvd-r for ps3 play back

Hello,
Im trying to figure out how to take an AVCHD edited movie from fce4 and burn it to dvd-r so i can play it back on ps3 at full hd resolution. Thanks for any help!

You can't do it with iDVD.
You can do it with Toast 9 and DVD Studio Pro (which is part of Final Cut Studio).

HDV or AVCHD editing = processor utilization = import/exp. quality loss

Hello,
my question about processability of HDV/AVCHD Movies with iMovie. I have learned that HDV and AVCHD files are transfered in the AIC format. That should mean editig a movie would be always in the AIC format and I assume no difference whether I come from HDV or AVCHD format it should be similar demanding to the core2duo processor except initial transcoding from H264 to AIC - is this right?. When I save a movie out of iMovie do I save it in AIC or in HDV/AVCHD? Is there a quality loss transferring a movie back and forth from/to HDV/AVCHD to AIC since HDV employs mpeg2 and AVCHD employs H264 which are both compressed formats? Practically does this also mean that AIC can work as a bridge to between both formats?
Thanks for your replies to my several questions!

I have cut/pasted this from another thread where I posted it following a question from a Canon HV20 owner. The info applies to all HDV and AVCHD cams though. Might help you decide.
This comes from www.camcorderinfo.com
Compression (7.0)
The Canon HV20 (Review, Specs, Recent News, $903) uses HDV compression, a very efficient MPEG-2 codec with a fixed data rate of 25Mbps, identical to the data rate of standard definition DV compression. HDV excels in capturing stunningly high-resolution video, but it is inferior to DV in terms of rendering motion realistically, due to its dependence on interframe compression. This means that at 1080i, only one in fifteen frames is a full-frame picture, while the intervening frames are compressed in relation to each full I frame. Interframe compression is much more efficient than intraframe compression, and allows HDV to squeeze a full 1920 x 1080 picture into a 25Mbps stream, recordable to inexpensive MiniDV tapes. DV uses intraframe compression, so each frame is a fully independent picture, allowing much better motion capture. DV also uses a superior 4:1:1 color space while HDV encodes via a truncated 4:2:0 color space.
The inherent weaknesses of HDV have led many networks to deem the format sub-standard for broadcast, but it is still the best high definition format available on the consumer camcorder market. Most consumers find the stunning resolution of HDV trumps the superior motion handling of DV. A professionally lit HDV interview (or any HDV shot without too much detail or motion) can look nearly as good as footage shot in a professional HD format on a $20,000 camera. AVCHD, a new HD format that uses H.264 compression was introduced in 2006 and compresses video even more aggressively than HDV. Our tests of Canon's UX1 (Review, Specs, Recent News, $729.95) and SR1 (Review, Specs, Recent News, $1119.99) last fall show that while AVCHD video is very sharp, it suffers from grain and artifacts much more than HDV compression. The wildcard in the consumer high definition arena is a new MPEG-2 format developed by JVC, the MPEG Transfer Stream codec, which appears for the first time in the Everio HD7 (Review, Specs, Recent News, $1529). MPEG Transport Stream compresses video at up to 30Mbps, and may rival or even outclass HDV compression.
Media (6.0)
Like other HDV camcorders, the Canon HV20 records to MiniDV cassettes, the same inexpensive and widely available format used by standard definition DV camcorders. MiniDV cassettes have a run time of 60 minutes in SP mode, but can hold up to 90 minutes of more compressed LP video. Unlike the DVD, memory card, and HDD formats, MiniDV tapes are linear media so moving clips to a PC from tape is a real-time process. For anyone serious about the quality of his or her video, HDV recorded to MiniDV cassette remains the best consumer HD option available. To date, consumer non-linear video formats do not support the highest-quality video compression codices for high definition (HDV) and standard definition (DV).

RAM...KIT or DIMM for HDV Editing?

I need to add some more RAM to my Power Mac G5 Quad (pre-Intel), should I get KIT or DIMM (I don't know the difference), what works best for HDV Editing in FCP?
Also, any brand or vendor suggestions?
Many thanks. : )

Crucial.com. Other than that, I don't know, because I always buy direct from a distributor or the manufacturer at reseller pricing.
BTW, when I referred to 'matched DIMMs', I was referring to DIMMs with consecutive serial numbers, as Kingston used to do it. Don't know if they still do that, but 'matched' means, or used to mean, more than just the same size. FWIW.

Intel 960 vs dual Xeon E5520 for AVCHD editing

Like many people on this forum I am trying to determine the best hardware to purchase for my use of Premiere Pro. For the last several years I have been using Liquid Edition but decided to move over to Premiere because of its support for AVCHD editing.
I have narrowed my system choice between a single processor i7-960 and a dual processor xeon E5520. From the PPBM4 benchmarks it appears that a 960 system is sligthly ahead of the xeon system which surprises me. However, the results does vary based on task. An added benefit is that the 960 system is cheaper to build. On the other hand, Adobe seems to recommend a dual processor system for HD editing.
My question is which system is better at AVCHD editing? For the tasks that you routinely do in Premiere which configuration would better suit me?
Thanks for any help.

There are a number of things to consider:
1. Price/performance
2. Number of CPU's and cores
3. Clock speed
4. Memory slots
5. Overclock ability
What are the factors in favor of the i7-960 in comparison to dual E5520:
1. Price/performance
3. Clock speed
5. Overclock ability
so that means that dual E5520 have in in their favor:
2. Double CPU's and double the number of cores
4. Twice the memory slots (12 or even 18 versus 6)
When looking at the PPBM results, the i7-960 @ 3.2 performs around equal to dual E5520 @ 2.26. So effectively double the cores and lower the clock speed gives around the same performance. However, overclocking can have a significant impact as you see in the top results and that is where dual Xeons have a problem. Servertype mobo's are very difficult to overclock if at all (the same applies to Dell XPS BTW, because of their crippled BIOS). But the servertype mobo's have double or triple the memory slots of an X58 mobo and with CS5 around the corner, that may be a distinct advantage, because you can at reasonable prices go for 24 or even 36 GB memory.
However you remain limited to the standard clock speed and E5520 are not very fast. On the other hand if you were to build the system yourself, you could get an i7-930 at half the price of a i7-960 and overclock it to let's say 3.6 and it will be faster than both a single i7-960 and a dual E5520 at stock speeds.
Unfortunately, there are no tests specifically for AVCHD (there may be in the future for CS5) so a definite answer can not be given to your question, but keep in mind that all the top scores were achieved with raid configurations, so that is an aspect that should not be forgotten.
My advise: Depending on your budget, calculate between 30 - 50% of your budget for disks and raid controller. That will probably limit your choices.
If you have indefinite means available, I would go for dual W5590 or the new Gulftown hexacores, at least 24 GB RAM and an Areca 1880iX-24 with 24 Seagate Cheetah 15K.7 600 GB disks in raid30 and 4 SSD's in raid10 for boot disk. Add a nice nVidia card and a Tesla C2000 co-processor and you are equipped for the next coming years.

Multi-camera AVCHD editing workflow in Premiere CS4

I have a client project that has me wondering what workflow to use and I someone on this forum probably has the expertise to know the right solution. My requirements...
1. Client is recording a scene using 4 cameras at once, like a live TV show is shot, all AVCHD footage, 1920x1080px 17mbs, square pixels.
2. I must playback in Premiere the 4 video streams in real time and choose one camera to output, like a director would switch a live TV show. So, all 4 streams are playing in Premiere's multiple-camera editing windows. Each show I'm editing is about 1 hour long. The advantage of multi-camera editing of course is I can play all 4 cameras at once and live switch between them in Premiere to arrive at a 1 hour show in 1 hour of editing time.
3. Until I can upgrade my hardware that can possibly handle 4 streams of AVCHD, I'm stuck needing a workflow to convert the original AVCHD to some lowres format, edit those offline low res copies to get my edit decision list, and then reconnect the online HDV AVCHD clips to export through Media Encoder for a final production. My output format is Flash F4V 640x360 px square pixels for Internet playback.
4. Hardware: I'm running Windows 7 RC using CS4 Premiere 4.1, 4gb RAM, 2.4ghz dual-core processor with 64mb Intel turbo boost on a notebook PC. I do have 4 hard drives to hold each camera's footage on its own drive, and a fifth drive to ouput the edited version to, in addition to a drive to hold my OS and Premiere. The external drives are connected via eSATA to the notebook.
Question 1: what do you suggest as the lowres format I should convert my AVCHD footage to for multi-camera playback/editing in Premiere?
Question 2: do you think it's even possible to buy a desktop PC that can handle playback of 4 multicam AVCHD native format files in Premiere in real time? I'm concerned this may be too much for even the most powerful systems, and I would need to resort to editing lowres footage even with the most powerful desktop. As you know, decompressing one or two AVCHD streams is taxing to a PC so 4 at once is a challenge.
Question 3: an alternative workflow would be to feed live video out of the HDMI connectors on the cameras into four HDMI capture cards (Intensity Blackmagic) and capture uncompressed HDV bypassing AVCHD compression altogether, but the disk space required would be substantial. Does this make sense? I've even considered feeding those 4 HDMI feeds into a video switcher between the cameras and PCs but the cheapest solution I can find that can provide genlock (frame sync) between the 4 cameras for clean glitch-free switching is quite expensive, thousands of dollars invested.

I must playback in Premiere the 4 video streams in real time
Good luck with that. Many folks have trouble with even one stream.
edit those offline low res copies to get my edit decision list
I'm not sure offline editing with AVCHD will be possible because of the folder structure. You may not be able to 'replace' the lower res copies with AVCHD.
My output format is Flash F4V 640x360 px square pixels for Internet playback.
Oh, man. Shooting HD of any flavor is just overkill that adds unnecessary work to the process. Have your client shoot in DV.

HDV, AVCHD or What?

Well, it's July 2009. Assuming you have a powerful enough computer, does PPro CS4 easily support AVCHD? Or should I only look at HDV cameras?

Can you explain to me what the benefit of this approach is in comparison to just firewire?
Quality wise - Absolutely none and i have not even claimed that there is or should be any. I know all about "Once you have your shots on tape...". already and dont disagree on that.
If one has the need to work with uncompressed HD or with the Cineform codec i think the benifit is that i dont need to transcode the footage when the FireWire capture is done. Any MPEG2 can be frustrating to work with for many reasons so the ability to easy conform the media into another codec in real time during the HDMI/HD-SDI capture for a smoother editing experience is worth it sometimes. And, HDMI + FireWire, HD-SDI + FireWire or Component + FireWire keeps the original timecode in the captured file for easy frame accurate re-captures when/if needed.
Some people will disagree and some people will agree.
The actual video capture is done throught the HMDI/HD-SDI interface while the FireWire cable only carries the timecode and give the user the ability to control the camera/deck. (I dont know if any metadata is carried over since i never use it nor have the need for it...)
But again, there is no gain in picture quality. However, for post work with multiple render generations its a great benifit though as long as you avoid the Blackmagic Design Motion JPEG codec.
Btw, HDV is 1440x1080.

What exact file format for exporting AVCHD to HDD of Sony HDR-SR12E (AVCHD) Handycam?

When you are finished editing AVCHD files with Adobe Premiere Elements 11, what is the correct file format for exporting back to the hard drive of the Sony HDR-SR12E handycam?
I used Sony Play Memories software to import AVCHD (.m2Ts) files at 1920x1080i PAL resolution. I tried rendering to several file formats after editing, but the files could not be exported in high definition back to the hard drive of the AVCHD camera.
I WAS able to import files from camera in Play Memories and then export them straight back to camera WITHOUT any editing, but of course you wouldn't bother doing this normally.
I grew to love using Premiere Elements 10 for editing sd footage from my mini dv camera. However, I've just purchased the AVCHD handycam and expect to receive my newly purchased copy of Premiere Elements 11 in a couple of days.
Can anybody suggest the correct file format to produce for exporting AVCHD footage edited in PE11 originally captured on the Sony HDR-SR12E back to the camera?
- Regards, Phil

Phil
Premiere Elements 10 has the Share/Tape (Record to DV). And, even that is for just DV, not HDV. There is no such choice in Premiere Elements 11 and 12.
So, you are going to have to match up the properties of the original with Export settings and try to get the file exported onto the camera's hard drive if that is possible. Does the Sony user guide give instructions for how to import one of your video to its hard drive?
The theory depends on how close you want the export of the edit to match the camera's original. There is no .m2ts file extension in any of the Publish+Share/Computer/AVCHD choices. If the .m2ts file extension is a must..
One scheme to get a AVCHD.m2ts 1920 x 1080i25 for your camera's hard drive - lots of ifs
1. Publish+Share/Disc/AVCHD and burn to folder using presets = H.264 1920 x 1080i PAL Dolby.
(The preset cannot be customized so you will go with the Adobe bitrate.for the preset)
2. Then go to the folder saved to the computer's hard drive, open the BDMV Folder, then the STREAM Folder of the BDMV Folder, and use the 00000.m2ts file there as your file destined for your camera's hard drive.
If the hard drive will accept ..m2t, then you could use Publish+Share/Computer/AVCHD with Presets = M2T - H.264 1920 x 1080i25 and customize the export settings under the Advanced Tab/Video Tab and Audio Tab.
Please review and then let us know if any of this works for you.
Thanks.

What are the REAL system requirements for High Definition Editing?

According to Apple, you can edit HD in iMovie with: a G4 1GHz or faster processor, 512MB RAM or higher, and OSX 10.3.6 or higher.
I am running a G4 iMac 1.25GHz with 512MB DDR SDRAM and Tiger 10.4.3
My machine can barely import HD from my new Sony HDV1080i camcorder. It imports at anywhere from 1/8th speed to 1/2 speed.
But more importantly, the playback in iMovie of my HD clips is not smooth -- the playback looks jagged, as if the computer cannot quite keep up at full speed.
Would upgrading from 512MB RAM to 1G RAM likely solve my problems with the slow import and the jagged playback?

Would upgrading from 512MB RAM to 1G RAM likely solve my problems with the slow import and the jagged playback?
No. A faster Mac with a faster video card will help.
The playback in iMovie is never as good as it will be on TV, even on DV. It must be even more difference for HDV.

Sequence settings for HDV 720p 24 fps

Okay, now that the French is gone I'm back on track, but still confused. I've captured my HDV 720p @ 24FPS footage using LumiereHD & it's separated & ready to go. What sequence settings/editing timebase should I use? I've noted people here saying DVCPro, but others said DVCPro is just problemic/not correct for HDV . . . and the Lumiere forum reccomends using the Apple Intermediate Codec, which I think people here said NOT to do . . . and there's a 720p24 option in Lumiere, but not in FCP . . . is it just like using 24p DV where you edit at regular 29.97? My head is turing into goo. Any sage advice, O sage ones? And I'm finishing on DVD, if that's usefull. Thank you!!!

Don't stay nervous for ever, you're missing out on a lot of good stuff.
1. Repair Permissions.
2. update to OS X 10.4.8
http://www.apple.com/support/downloads/
3. update QuickTime to 7.1.3
4. make sure you have Motion 2.1 already installed
5. update all your pro apps with Software Update
http://www.kenstone.net/fcphomepage/whats_new_5.1.2balis.html
http://discussions.apple.com/message.jspa?messageID=3213777
Still nervous?
I can't tell you what setting in FCP 5.1 to use, because I no longer have 5.1.
I would convert the HDV to DVC PRO HD 720p.
Editing in native HDV is a pain because of the frame structure.
You will end up with larger files with DVC PRO HD, but since it's all "I-frames" editing and compositing will be much, much faster.

How is this for a PC spec for home video editing?

OK - we've decided to get the new PC now, focused around decent performance for video editing at home when we do it. Any feedback on the below would be greatly appreciated. I've tried to put in my "principles", but as you note I've highlighted some questions around these.
Principles
* Decent computer for Home Video Editing - so when we do it want it to be reasonable from a performance point of view (not annoying). Also want assurance for the video data that a single HDD crash won't mean lost data.
* Hard Drive Configuration - Assume RAID 1 for data
C: 500GB - Operating System (1 x 500GB)
D: 500GB - Swap Area for O/S (1 x 500GB)
E: RAID 1 Redundancy for Data ( 2 x 1TB )
* 64 bit Windows 7 Pro
* Questions re Principles
Is it really worth having a separate drive (D: drive) for Swap?
Is there any real need to have a drive F: (another one) for exports? This is non-real time so it shouldn't be an issue should it?
Any major improvement re moving say the C: drive to SSD? (or not worth the $$)
SATA II versus SATA III drives? (I've assumed both are ok when picking)
The Spec
CPU - Intel Core i7 960 Processor LGA1366 3.2GHz 8MB Cache CPU
Motherboard - Gigabyte GA-X58A-UD3R X58+ICH10R QPI 6.4GT/s DDR3 2000 PCI-Ex16 SATAII SATA3 USB3.0 RAID GLAN ATX
RAM - Kingston 12GB(3X4G) KIT 1333MHz(PC3-10600)
Video Card - NVIDIA GTX560 - Gigabyte GTX560 OC 1G GDDR5 PCIE DualLink DVI [?? matches motherboard / is this overkill ??]
RAID Card - Adaptec AAR1220SA-SGL SATAII RAID0 1 JBOD/2 PORT/Low Profile/PCIEx1/OEM/No Cables [?? is this ok - seems cheap ??]
HDD (non-RAID) - 2 x Western Digital 500G RE4 SATAII 7200rpm HDD 64MB Enterprise [?? only SATAII this is ok no??]
Case - CoolerMaster RC-942-KKN1 HAF X 942 Black No PSU [?? is this overkill - just took someone recommendation here ??]
Power Supply - Corsair HX-850 ATX Power Supply w 140mm Modular Cables [?? power ok? again just took a recommendation ??]
O/S - 64bit - Microsoft Windows 7 Pro 64bit OEM(Microsoft OEM Terms&condition apply)
Note - I'm looking at the following local site re where to source if this assists: http://www.umart.com.au

Greg (correct me if that's not correct!),
You're spec. looks like a great start for what you are trying to do. I have a few comments, and also two questions!
Comments:
- Spec. generally looks fine
- I particularly like your case and p/s choices!
- For a home PC, you may consider bumping up your OS choice to Ultimate, which adds some nice multimedia capabilities
- Regarding the D drive for swap (and I assume you mean Premiere Pro media cache and media cache database too) will definitely speed up aspects of Premiere Pro, but likely be unnoticeable for other home PC day to day use. Why not build out the system and decide then if you need the extra speed for Premiere Pro - it is so easy to add something like that later.
- I'd vote no regarding a need for a F output drive for this system
- Regarding your OS drive... Speed and responsiveness versus cost - what do you choose? This really is a personal choice. I will say that a 2x1TB RAID 0 OS boot array would probably be a bigger step up in performance than a similar priced SSD option and a 2xSSD (60 to 80GB) array will perform better than a single larger SSD.
- Sata II vs Sata III - I have some of each now, and I would agree with other posters and articles on the Internet that say the often larger cache size on the Sata III models is more important than the Sata III interface. Keep going like you are going, with the assumption that both are OK.
- finally, your CPU; personnaly, with the new lower cost pricing on the i7-970, I'd suggest you downgrade to a i7-950 and same some money or upgrade to the 32nm 6-core i7-970 CPU and jump to a significantly new level of performance and power per watt
Questions:
- what version of Premier Pro will you be running?
- what will be your workflow (i.e. DV, Sony consumer AVCHD, Canon DSLR, etc.)?
Cheers,
Jim

Correct settings for HDV capture

Hi. I'm using Premiere CS5.5. I went on a few forums to get the correct settings for HDV capture.
I can record the footage fine. However I saw a few things which didn't seem right.
After capturing the HDV footage, the file was a .mpeg file. Secondly, the clip was 1 hour and 10 minutes and
it was only 11.3 GB. Does this sound right? A 55 minute .avi file is 11.6GB. I thought a HDV clip would be quite a large size file.
If this dosen't sound right, is there somewhere I could go to, to check that my settings are correct? By the way I'm filming and capturing with a Canon XHA1.
The footage is 1080i. HDV. I've exported it and it looks fine. Just want to make sure I've captured it correctly and to the best quality.
Thanks for your help.

The HDV format was advanced by Sony and others to use the same miniDV tapes used for SD. In fact, your Canon XHAI can record and play either without changing the tape transport speed.
Your observation in relative file sizes is due to the fact that HDV is highly compressed (MPEG), whereas, SD (AVI) is not as highly compressed. This is one of the reasons folks (such as Harm) don't consider HDV to be an edit format, but just a delivery format.
Note that what Harm was saying is symantics--you capture an analog source through a capture card that digitizes it. When you transfer a image file from HDV or SD, it is already digitized, so a bit-to-bit transfer occurs.

[CS5] Project Manager Trimming not supported for HDV footage?

Yes, I have the licensed version of CS5 Production Premium.
The Premiere Pro "Project Manager" allows you to create a "trimmed" version of your project. That is, only the footage actually used in sequences (along with some handles) is placed in the new, trimmed project. For example, I have a project which uses only 1 second of an 11 second HD Quicktime clip.
original project folder which includes the clip = 352MB.
trimmed project folder is = 26MB
My problem is with a similar project using only a small portion of an HDV clip (M2T):
original project folder = 232MB
trimmed project folder = 232MB
There is nothing I can find int the Adobe help file regarding limitations for HDV files with the trim feature. This problem is not limited to CS5. I experienced it also in CS4 but resolving it was not a priority at the time. But I now have a large number of projects I wish to archive.

Jeremy, I am assuming that this is harder to solve, because it gets into Premiere and/or the mainconcept codec being used, not providing smart rendering. You can't just take the middle of an mpeg clip without rendering. Premiere could do this, but there would be a quality hit. Is there any chance we will see a more sophisticated approach to mpeg inside Premiere? And I am also interested in whether the long gop formats are/might be addressed differently from others.
Todd, here is the CS5 help file that should have this.
http://help.adobe.com/en_US/premierepro/cs/using/WS1c9bc5c2e465a58a91cf0b1038518aef7-7c74a .html
And it does not.
In earlier versions (I'm still CS3, and I think it was CS3 in which there was this discussion), I found that you could not work around this by creating a subclip. In fact, the original full clip would be repeated for each instance of the subclip.
