Hi Scot,
What is "HD footage"
Are we talking HDV or mpeg4 .h264 or AVCHD?
You will get away with a lot less if you have a HDV camcorder vis the newer .h264 ones.

Hi Tony,
I am sure you have posted this before elsewhere but what is your target playback device eg HD media player onto HD screen, for DVD production for distribution to others etc
I ask as this does affect what you do with your editing process.

This is the first post I have seen someone using level 5 profile. It is just possible that PD7 cannot cope with all that bitrate
PD8 needs to come sooner rather than later to deal with all the escalation in consumer product specs.

As a result is I get artifacts and jumpiness when the movie is produced.
The reason you get artifacts is that the AVCHD render engine is substandard in PD7. Any rendering will cause the artifacts. I use native video at less than 14800kbps and get crystal clear images from the camera. As soon as it is rendered at the same bitrate it intoduces artifacts.
The only way to avoid it is to use SVRT and of course you are stuck here as well because as you say, the bitrate limit is exceeded.
I am hoping the rumours about a new AVCHD render engine will come to fruition.
The best way to preserve image quality is to render to Mpeg2 BD profile but of course this doesn't help you if you want to use hybrid DVDs.

pjc,
Are you talking about a PDS file?
Hi Phil,
What I am suggesting is to create DVD folders on your hard drive. In the disc burning module there is an option in the final burn menu to create DVD folders and NOT to burn DVD disc.
You end up with a folder on you hard drive which is in DVD structure. Most PC based DVD players can play from folders. This way you do not waste physical disc determining if PD got it right or not. If the DVD folder creation was successful and it plays OK to your liking then you burn the actual DVD using eg Nero or freeware such as IMGburn.

Hi Phil,
To add to Robert's advice, I suggest you always burn to HDD (create folder) and then test the DVD structure and playback using your PC based DVD player eg Nero Showtime or PowerDVD.
If all is good you can then burn to disc (and I suggest you use a third party application here as well - saves re-encoding and has a better success rate for me)

Hi Tamas
that if we e.g. delete the last frame, using Panasonic's HD Writer program, and saved the m2ts file (quality / parameters remains the same), then PowerDirector SVRT function was working
This is interesting. I shall follow this up. I have not been able to get PD to recognise SD9 clips as compliant ever.
Supposedly Cyberlink are going to improve the awful AVCHD rendering with the next patch but I am a bit skeptical.
A work around is to use GPU rendering to AVCHD which does a reasonable job or use mpeg2 Blu-ray profile which gives excellent results albeit with the larger file size. Unfortunately you can't use mpeg2 for hybrid discs.

Again on the AVCHD side of things.....
Your card may be able to do rendering but you will need to update your drivers. Have a look here to see if your card can do it
Nvidia http://www.cyberlink.com/products/powerdirector/cuda-optimization_en_AU.html
ATI http://www.cyberlink.com/products/powerdirector/ati-optimization_en_AU.html
edit : I forgot to say hybrid discs can only be encoded with AVCHD and are not played on all BD Players.

I'm adding my support to your letter. My sentiments as well.
|
|
I have not seen the audio problem - very odd.
As for the Mpeg2HD > AVCHD ..... PD rendering of AVCHD is not as good as it should be with artifacts and compression blocking being introduced. They are addressing this apparently.
If your videocard can support video rendering then try using GPU rendering. My 8600GT does a better job and produces acceptable AVCHD hybrid discs.

Hi Nicholas,
Have you tried to render to a file only (either Mpeg2 or Mpeg4 AVCHD) ?
If you can create a file you might have better luck using a new project to create a disc from the rendered single file.
|
|
The answer is yes under certain constraints.
You need to use the SVRT function of the programme and unfortunately it is pretty fussy. If the original file is not pretty well exactly the same as PD's version of the output file it will get rendered.
Use the view SVRT option under the main menu and see if your M2TS file is recognised as compliant.
If it is compliant, you should be able to split the file, delete the segment you don't want then use SVRT to produce the file.
If your clips are from a Panasonic HD camera then you are out of luck

Hi Don,
I assume Cyberlink choose .m2ts container for their AVCHD as it is linked to BD standard and PD is aimed at Blu-Ray disc compatibility.
You can output .m2ts as individual files, not just to disc.
Many players (both stand alone and PC based) can handle .m2ts - and so they should as it will be very common format while BD is around.
I have no problems playing the .m2ts files on my gear. I do have a problem with the PD encoder but that is another story......
I do of course convert to lower res .mp4 for my iPhone and iPod.
|

But how can I move the time line, for example to the left ?
Unlike other NLEs you cannot do this in PD.
The work around is, for your example, to place a black colourboard on the video track in front of your editing and set the duration of the black video to 20 mins.
|
|
Set the default duration of titles (and other things) in "Preferences"
Alt+C>editing (third tab from left)>durations (lower half of window)
|
|
Why are you posting here....surely "Windows" notified you of the solution?
Sorry ... but you got to love Vista. (from an XP user )

Hi Robert,
Imgburn has settings to reduce burn speed and also verify burn. Although this is much longer it will result in more consistent burn.
Some DVD players will tolerate data errors better than others. PC based players are often the best but not always.
I have been in the situation where I have burnt 30 DVDs for school projects but never 100!. That is a lot. You would expect a few failed burns in that lot! Had you considered getting the master copied by a local business?
|
|
I have some interesting problems with the magic fix function as well.
Although it is seemingly wonderful when previewed in PowerDirector the rendered file plays back with some artifacts on my PC and when I use my networked mediaplayer to display on an HD plasma it produces an interesting artifact causing wide horizontal bands of distorted picture.
This happens if the file was shot as progressive or interlaced and rendered either as 1080i or 720p
The distortion is dynamic so I have taken a photo of the plasma display to illustrate. Notice the vertical poles on the trampoline and legs on the low table.
I can't pin this one down.

Hi Robert,
Do you have Nero or equivalent on your PC ie software apart from PD to burn discs?
If so try using the other burning software to burn the DVD folder you created.
The PowerDirector burn module is flawed and puts up lots of errors and has incomplete burns. These problems seem intermittent hence the trouble I suspect for Cyberlink to track down the problem(s).
For what it is worth, if I use the PD create disc module I always
1. burn to folder
2. check the disc structure using Nero Showtime then
3. use Imgburn (freeware) to actually burn the physical disc.
Hope this helps

thanks..... I got it working as far as the sound.. it was my avchd player I was using.. now what about eporting to an M2t file?? my camera shoots in M2T HD 1080I. I can then eput the chip directly into my blu-ray player and it plays the M2T files.. I want to be able to edit the files, then export back to M2t. how? I can do this in premiere elements... just cant figure out how in power director...
Hi Hauss,
I have the SD9 but I will make an assumption the files are the same.
The Panasonic records in the proprietary format AVCHD which has the file extension .MTS when created on the camera. When transferring to PC using the supplied software(HDWriter) the file extension is changed to .m2ts but the file is not altered. Panasonic have their own slightly tweaked algorithm which makes its handling by editors even harder.
You can of course just use the .MTS files in PD without changing the file extension.
After you produce in PD the resulting .m2ts file is different to the original as it uses more standard characteristics of AVCHD which makes it more compatible with different players (both PC based and stand alone). This is also why SVRT in PD does not work with Panasonic files.
I am sure you know how to make AVCHD (.m2ts) files in PD but just in case:
Produce>Create a file>AVC.MPEG4(use 1920x1080 & DD5.1 for best quality)>start rendering
You can then put them on a SDHC card (or USB) & your player should be able to read the .m2ts files if it can read the .MTS. (Is your BD player a Panasonic?)
A word of advice about PD:
The AVCHD rendering engine is not particularly good and it introduces artifacts and blocking. GPU rendering is better if your PCC/Videocard allows this. Apparently Cyberlink are addressing this in the next patch.
In my experience rendering to MPEG2 1080i Bluray profile results in the best PQ when compared to the original files off the camera (which is fantastic I must say). Of course the resulting file is larger than for MPEG4

Are you enquiring about PowerDirector or Power DVD?
