Subject: DV-L] Anyone editing in AVCHD?
Hi there,
I'm wondering if someone here can share their experiences editing
AVCHD footage. I'm aware that for most editing machines, you will have
to use an intermediate codec - the question in my mind is whether you
can actually live with all this intermediate codec stuff if you had to
edit this format on a daily basis (as opposed to editing footage a
client brought in shot on his home camcorder).

Right now with P2, you stick your memory card into your computer and
edit away. Which makes me wonder if it is at all smart to even
consider an AVCHD cam for a pro workflow.

Is it too slow? Is anyone editing AVCHD in real time? Is anyone HAPPY
editing AVCHD?

For my professional work video I shoot HDV, 24fps, with an XH A1. However, I have a little Sony TG1 just for home movie type things. I use FCP, Studio 2 until this week when I installed Studio 3.

There's basically no difference in FCP between editing AVCHD and anything else. You plug in the card and instead of going to capture, you go to  log and transfer menu. All the clips appear in a window and you can choose to load all of them or drag and drop selected clips to the window below.

The first time you do this you choose what you want. I use the high quality ProRes. You only have to do that once unless you want to change codecs.

Click OK and the footage transcodes and each clip appears in your browser window. I haven't timed it out, but I'd say a clip loads a little faster than it does with tape, plus you don't have to log every clip since they all appear at once. So overall it's faster.

Editing is normal. No problems at all. The only thing is with FCP you have to have an Intel Mac. The older pre-Intel Macs won't do AVCHD, but any one with the Intel chip does it easy. I don't like tapeless at this point and wouldn't use it for work purposes, but it is OK for the small amount I shoot for home movies.

Thanks for the input, Bill.

My question is actually regarding the use of AVCHD in a pro
environment - meaning daily editing of AVHCD footage, tight deadlines,
demanding edits, reliable output, etc. While it seems that FCP can
handle it using the Prores intermediate codec, I'm wondering if this
is workflow is practical in a pro environment (as mentioned above),
because I've got my mind set on the new Panny HMC150, which is like
the DVX100, but using the AVCHD codec. If its a bummer to edit, then I
might have to reconsider my choice.

You are saying that transcoding is a little faster than real time - I
guess that means there's some advantage there vs tape based formats
(DV, HDV, etc). But I guess its not the same as P2 which is stick in
the cartridge, dump the data and edit.

If anyone else has input, please let us know what you think!

My main consideration of using AVCHD / tapeless workflow in pro
environment will be a data backup and storage.
In tape, when the event has done, just eject the tape, and put it on archive.
In tapeless workflow, download from memory, then burn the data to backup disc.

I don't know about the rendering process to DVD resolution in FCP,
will it be longer (due to downscaling process also) ?
In Sony Vegas, downconverting process to DVD takes a bit longer rendering time.

Perhaps you want to try to make a test by downloading AVCHD raw
sample, make a test edit with available footages.
Google for 'HMC150 AVCHD raw sample'...

Hope helpful,

Setiawan

I'm not sure what you mean by dumping the data in P2. How long does it take for it to copy over? If it goes really fast, then P2 would be faster. If it goes in real time or slightly faster, then it would be the same. Transcoding is about the same as loading from tape, no more hassle. I wouldn't have a problem with editing it daily as I do footage from tape. My only issue with any tapeless format at this point is that I don't want to have to download and back up the data on location, which is what you do with P2. I shoot so many tapes for professional purposes that would be impractical, and on some shows the shoot may happen a couple of months before the edit and I don't want to spend the time to load and backup things.

But that's not relevant to your issue since you're acclimated to tapeless already. If P2 lands in your browser immediately, then you wouldn't have the loading time you do with AVCHD. Other than that, it should be the same. You don't have to transcode the AVCHD to ProRes 422, you can use anything. Basically, you can't tell any difference from the footage just capturing in the normal manner. I would be inclined to go with the AVCHD camera because the media is not a proprietary and expensive thing. The cards are cheap enough so a guy could buy extra and not worry about offloading and backing up several hours of footage every day if you shoot a lot.

That would be the logical thing to do--a test. See how it works for you. I don't think compressing for DVD would be any different. I export my timelines as a 1920 x 1080 H.254 best quality before compressing for DVD, or to PNG if time permits, though frankly I can't see any difference from the H.264. Lots of people export directly from the timeline to a DVD compression in FCP but I always do the H.264 which becomes my master that I  save with a backup to DVD storage.

Thanks for the input on this - I was all set to download some HMC151
AVCHD footage and do some tests, when I realized that I was editing on
FCP5.1, which doesn't have the integration with AVCHD built into it
yet. Aargh.

I've ordered FCPStudio3 which has AVCHD integration built-in via
transcoding to Prores, but its arriving in a week so have to hold off
on that test.

I suspect, though, that AVCHD and other long GOP codec is the way the
world is going. In a year or so, the faster multicore CPUs will be
everywhere and we may all be editing AVCHD natively.

I've not personally tried P2, but SxS (XDCamEX) goes in at around 6x on a
decent laptop. I would imagine P2 is similar.
XDCamHD is limited by the BlueRay process to around x2. I would imagine the
consumer card systems would be similarly limited.

FCP edits AVCHD via an interim 'ProRes' codec. It would be interesting to
know if there are any edit systems that keep it 'native' in the AVCHD codec?

Sony Vegas Pro does it natively, whether that is Sony's AVCHD or
Panny's AVCHD (requires minimum 8.0c).

Subject: RE: [DV-L] Re: DV-L] Anyone editing in AVCHD?
I thought AVCHD was a joint Panny/Sony standard (with others) and therefore
the same (like DV and HDV). DV was notorious for having different 'versions'
of essentially the same codec. Quicktime (for instance) wouldn't open a DV
movie with the wrong 'publisher's' version. I always suspected that there
was more politics than science in this situation!
Interestingly a computer magazine I was browsing in a store yesterday had a
review of consumer video edit apps - they thought Vegas Movie Studio was the
best performer but was perhaps too different an interface to be readily
accepted. It was of course derived from an audio editor and therefore does
seem rather alien to the video fraternity!
I would expect a native editor to require vastly less storage resources for
the rushes (compared to one like FCP using an interim codec). In these days
of cheap TB drives I guess that it may be irrelevant to most producers.

I have Sony CX7EK, and got a chance to make test recording during
HMC152's road show several months ago.

First I found them different is when I put Panny's AVCHD to VegasPro
8.0a, the apps goes crashed immediately. Then in VegasPro 8.0c release
notes, written Panasonic's AVCHD is now supported. The folder
structure in memory card is also slightly different.

Opening Sony's AVCHD in Panny's AVCCAM free utility (can be downloaded
from their website) is also directly rejected.
(Message Box : "The Application only works with Panasonic Cameras!")
https://eww.pavc.panasonic.co.jp/pro-av/support/desk/e/download.htm#a...
Just found and remembered that there's a free tool too to convert
AVCHD to P2 DVCProHD.

Adobe CS4 able to edit AVCHD natively too, but I never tried it.

Sony Vegas, yep, it's interface feels very different as it is
basically an audio software before. But, what I like with Vegas Pro
right now is it also feels like After Effects, freely to move the
tracks up or down.
I agree too as doing editing natively if possible, so, the video files
are ready to edit, no need to do conversion of anything.

In this case you are using DVCProHD as an interim codec, it just happens
that it is an acquisition codec as well. I have no real knowledge of this -
but my gut feeling says that there must be better edit codecs around if you
don't need to go back out to DVCProHD. Lossless would be better if you have
the space.
It's a little old - but this site may give you some thoughts:

Subject: Re: [DV-L] Re: DV-L] Anyone editing in AVCHD?
I believe this is what gives P2 systems their advantage (hence
additional outrageous cost) - the ability to go right from camera to
edit with no transcoding. For some folks (Maybe news crews) that speed
advantage is worth paying for, much like Betacam was in the linear
days (you pop in the tape, you edit the shot, you are done).

With AVCHD, you save on the acquisition but pay on the editing side.
Then again, my attraction to AVCHD is that computer power gets very
cheap very fast, while P2 cams stay expensive very long. This is why I
am thinking that AVCHD has a bright future ahead of it.

Its interesting how Vegas can edit AVCHD natively, while others still
can't (or in the case of FCP, wont). Probably means there is a lot of
improvement yet to be seen in editing systems.

Perry,
I can't imagine how we can discuss uncompressed codecs in this
context. If AVCHD is hard enough to edit with existing hardware, wont
this be the same problem with uncompressed?

BTW, that link you shared earlier was sooo hard to understand. Is that
the stuff you read for entertainment?

Subject: RE: [DV-L] Re: DV-L] Anyone editing in AVCHD?
Basically you have two problems in the edit domain:
1)Storage space and data rate
2)Codec processing power

Uncompressed HD consumes around a Gb/s, call it a 100MB/s. This is still a
very serious data rate but it is now well in the ball park of a normal
desktop computer. A modest RAID system will allow you to edit multiple
streams. A hour of uncompressed footage is several hundred GB, but with TB
drives now the 'norm' it is no longer a real barrier for even consumer use.

Modern processors, often with Graphic board acceleration, can munch through
common long GOP codecs with ease. However, in my experience there is some
way to go to make this a 'gimme'. In an edit you may well need to be
decoding several streams of AVCHD data, processing them together in some
form of 'effect', displaying all the relevant pictures, and probably
re-encoding back to AVCHD (or whatever selected) for the rendered result. It
has to do this over many frames at the same time. It is no wonder that this
is at the cutting edge of current processor technology!
Uncompressed has no such processor demands - basically the less compression;
the easier it is to process.

Sorry about the article - I just found it in a Google search and it seemed
relevant. It seems to be a university thesis! (I must confess I only read
the synopsis)

So.....in easier words:

Uncompressed:
The Hard Drive and Storage speed is challenged, while computer
processors remained 'cool & relaxed', but you got a perfect & clean
picture of every frame.

in contrast, AVCHD:
Storage is not much a problem, BUT, computer's processing power for
'decoding' picture is challenged.

On the link that Perry shares, as long as I know, these are Lossless
and, perhaps, freeware/opensource codecs, well, those can be an option
too, although no idea of how they works or affects the video quality,
or how they are going to be in professional environment.

Anyone here ever try, as suggested on that review, Lagarith compression ?

(A bit different topic)
I have one here installed, but haven't been used.
Reason: I surfed and found the 'Deshaker' utility (as a 'plug-in') for
freeware apps of 'VirtualDub'.
Deshaker able to minimize camera or picture shakes.
But, VirtualDub (or any graphics and video utility) unable to read any
of Sony Vegas internal codecs (these codecs only works in Sony Vegas
apps) or HDV or AVCHDs.
So, maybe Lagarith can become a bridge.
A bit strange thought perhaps, but, don't know if it works... I
haven't been able to try them.
