As on date all the editors which you have listed have trouble editing AVCHD.
pjc 's post shall also be noted.
PD7 doesn't have trouble editing AVCHD - it goes it very well. Rendering is another story.
One caveat though - I agree with others that if the project gets too big it becomes a little unstable. I limit to about 30 mins for each section and have no problems.
AVCHD is a compressed format
So is just about every other format.

Hi Nick,
I own (or have owned) all but Premiere 7 (my last version of Premiere was 6).
Unfortunately for you no solution is "the best"
Without getting the topic locked by talking about the virtues of the other editors, Powerdirector is probably the best for AVCHD editing at the moment if you take into balance features, stability and ease of use. However search AVCHD on this forum and have a read about AVCHD rendering. My workflow is to render to MPEG2 1080i due to the problems. We are hopeful that Dafydd (Mod) is onto it for us and we might get some action on the AVCHD rendering front soon.

Hi David & welcome,
The clips you present seem to exhibit interlacing artifacts probably because you are converting progressive footage to interlaced. We all know there shouldn't be a problem with changing progressive to interlaced but it looks superficially that the field order has been switched and the first field from one progressive frame has been combined with the second field from the previous frame.
What the rest of this thread is mostly about is introducing blocking and compression artifact with resultant loss of "definition".
The artifacts I get are reproducable whether the clip is an individual with no "editing" or in a large project with losts of manipulation. Thanks for adding some more interest to this topic. : Nice camera BTW

The ShadowEditFile folder is a temporary storage folder, the contents are normally deleted when you close PowerDirector, however, files can remain if PD7 crashes. You can safely delete the contents of this folder.
Robert
I disagree with parts of that advice. My "shadow files" are copies of AVCHD files which are created if I use the "smart proxy" feature. They are not deleted when I close a project and I am glad as then they would have to be re-created every time I open the project.

Thanks pjc.
Another question. On a very fast computer, how long should it take (approx) to produce titles for mpeg2 and burn a DVD that is 1 hour in length?
Thanks,
- Andy
Quad core 2.8GHz (Q9550)
1hr of mpeg2 to DVD HQ (no SVRT) 25mins CPU at 30%
1hr of AVCHD 1080i to DVD HQ 40 mins CPU at 75%
1hr of DV to DVD HQ 25 mins CPU at 55%
I aborted rendering at about 20% each time after the "time remaining" was consistent but should be a pretty accurate estimate for the 1 hr of rendering.

producing titles is the process of converting your video footage in the project to DVD compliant mepg2 format before it burns to DVD. You may even be using mpeg2 footage in your project but if the parameters are not DVD compliant then it will render them all. DVD specifications are pretty fussy.
The time to do this depends very much on your processor.

Have you downloaded the latest forceware drivers, as the checkbox should be enabled amd the 8600 does have CUDA ability.
Have done that thanks David. I was using CUDA before the last patch but didn't bother as it actually slowed my rendering down.

Its quite off putting - and although probably unrelated, if i make a normal (SD) DVD from my AVCHD files, the quality is noticable degraded Russ
Hi Russ,
I absolutely concur. If I want to make a DVD I render to Mpeg2 HD (blu-ray profile) to avoid the poor AVCHD rendering then use another application to burn to DVD to avoid the poor downscaling. This is a shame as the disc module in PD is pretty flexible for an editing programme. Luckily I usually just stream the Mpeg2 HD to my media player.
Another option I use if I know the project is just for DVD is to use the bundled camera software to convert to mpeg2 prior to editing then PD is great all the way through.

What are the other specs of your PC?
I found CUDA to be uninspiring so far.
Intel E8400 with 4GB memory, Vista 32
I haven't enabled CUDA since the last patch. I notice now it has a note saying it will be disabled if your graphics card is not up to the task.
I suspect my combination of Q9550 and GT 8600 means no gain in GPU rendering and it is not enabled during rendering (check box is greyed out).
Anyway it is so limited to which effects it is used there is no real point for me.

Do PDR developer read this? Come on man! It doesn't take much to program and fix this!
The answer is no they don't read this but Dafydd the moderator does and he seems to have very good communication channels with Cyberlink. He has taken the issue up which is great so maybe we might get some action on the AVCHD front.
It is not just the poor implementation of SVRT but the poor rendering engine in PD for AVCHD. I personally don't mind rendering all the clips if the output was of the same quality but it is not. That said it would be best if SVRT and rendering were both fixed.

HF100, not technically mine but I use it a lot - I like to have two angles for lots of stuff.

Cool, thanks for that,
I will only import the .mts files into PD and see how I go.
Hi Bobby,
Just read your PM, sorry about that (and to Dafydd as well for lack of response to a PM). Only found it when I PMed Dafydd on another matter.
Anyway I will describe my workflow but remember I have PD7. This is for stuff from my SD9 not the HF100.
The best result in terms of preserving quality is definitely:
transfer .MTS files from SD9 to HDD by simple drop & drag>import .MTS into PD and edit>render to file using Blu-ray MPEG2 format> play using networked mediaplayer to HD Plasma.
If you want the best preserved quality for a standard DVD:
Transfer .MTS files from SD9 and convert to mpeg2 (standard definition) using HD writer>edit in PD> burn in PD
or
transfer .MTS files from SD9 to HDD by simple drop & drag>import .MTS into PD and edit>render to file using Blu-ray MPEG2 format> create DVD using 3rd party application.
Essentially although I am very happy with PD for it's interface and features, it's rendering and converting of AVCHD is not yet as good as some of it's competitors. That said I stilll use it as my preferred editor over Studio, Vegas and Videostudio.

- pjc, rendering to mpeg-2 present several disvantages. First, increase in file size. Second, the re-encoding always results in lost of quality. Third, longer rendering time. fourth, the re-encoding always results in lost of quality (yeah, it's bad, inadequate, unsatisfactory, deficient, malignant, carcinogenic, etc), sorry I can't stress this enough.
Juan
Juan, I can't agree more but in my workflow MPEG2 is the only real option at the moment.
SVRT works as you say for the first clip for my Canon but SVRT doesn't work at all for my Pana SD9 due to the slight quirks Pana have used when using their own interpretation of the AVCHD codec.
So at the moment I am stuck until they sort it out.
As for the clips to Dafydd - I cannot believe Cyberlink wouldn't already have access to clips of all the main players in AVCHD cameras. But I shall PM him and send a clip from both cameras.

I have posted several thing about AVCHD in the past (search AVCHD) and have essentially given up on PD7's AVCHD rendering. I render to MPEG2 (Blu-ray template) and this is almost indistinguishable from the original AVCHD files but of course lose the benefits of file size.

Hi Angel,
I can confirm that I have no problem importing AVCHD or Mpeg2 files with 5.1 DD audio.

I have opened a support case with Cyberlink about the AVCHD final quality. I would suggest that everyone else who is noticing the same issue also open support cases, that way they realize it is a widespread and noticeable issue that needs to be addressed.
I submitted a support ticket a while ago but I got such inappropriate responses that I gave up.
PD7 is still my preferred editor of the four I have but it would be much better if I could not have to bypass AVCHD rendering in production.

AVI is a container format which can contain many different video and audio types.
Also just because other media players have access to codecs installed on your computer it does not necessarily mean PD uses them.
What was the original file from?
It might help if you downloaded an application like mediainfo which can let you know what is inside the files.

In it's current state though (on the 32" 720p LCD next to my computer for PS3 gaming), I can't tell the difference between a raw MTS file and a PD7 burned AVCHD disk.
Have there been edits with the .MTS files to require rendering or would they have been burnt using SVRT and hence be identical to the original?

Regardless, I turn on the CUDA option just in case it does something good.
As I have pointed out, depending on your processor/video card specs there may be a detrimental effect using CUDA.
