I am testing the trial version of Power Director 8. I have a clipped 20 meg WMV file to turn into video.

Produced in DV-AVI it is 538 megs!

Tried Windows AVI and will it not allow, as said wide screen not supported.

Produced as DivX it was 1.3 gigs!!

Tried various WMV settings but quality very poor.

What settings does one have to use to get near lossless output production with same size at input?

Hi Curt,

File format:

.WMV

Profile type:

Windows Media Video 9 HD High Quality

It takes a long time to produce it, but it always looks great and is quite crisp for such a relatively small file size.

Regards,
David

Hi,
The Windows Media Video 9 HD High Quality David has mentioned has one "little " issue with it as a template. It isn't a 16:9 frame sized template. It is in fact 4:3 and 1440x1080.

True 16:9 HD wmv would be 1920 x1080.

The Standard wmv selection is 16:9 of 1280 x 720.

Alternatively you can create your own template for a wmv. Please look up the following video tutorial: http://seemyworldonvideo.com/view/218/creating-wmv-templates/
Note: it was made for PD7 but it applies to PD8.

hi Curt,
I nearly forgot, DivX encoding issue has been reported and confirmed re: overly large video file size. What version of DivX are you using and what is the codec involved?

There appears to be a PD8/DivX codec conflict - one particular codec. A corrective patch is being made.

Thanks for the reply, and will try Windows Media 9.

Being a newbie I still do not understand why, when you start with a 20 meg file and render it, you come up with a much larger file.

Just intuitively it seems that the output has to be smaller or equal to the input, even with 0 % compression. How can you add data that is 30 times larger than the input?

Hi Curt,
I think you've not grasp what I've written and viewed the video information.

With the assistance of vn800rider: http://en.wikipedia.org/wiki/Video_compression

I have read about compression at length before posting. Does not mean I am anywhere an expert however.

I have tried various compression codecs as in post 1. Perhaps I am missing the concept of video, but if you take a 20 meg video, and use a compression codec than how can it end up much larger than the original?

For instance used Virtualdub and I took a 28mb AVI and ran the compression codec Cinepak by Radius and the file size was 115mb. How does this make any sense? Don't know yet how to do this in Power Director, but the end result should be the same.

I am a newbie, so if there are things I am missing on setting up the codec please let me know.

Thanks

Here's something you may want to consider if you attempt to modify the WMV HD format as demonstrated in the tutorial. In my case I didn't have the Window Media Encoder software installed so when I tried to open the files I could not open them. If you do a google search for Windows Media Encoder it will take you Microsoft's website where you can download the software for free. Once I did that I could edit the WMV HD profile for 1920x1080. One thing which I noticed in PD 8 is that now I have two profiles called WMV HD high quality. However, in the details it shows the different resolutions. Just be careful to check which one was selected prior to producing your video since WMV takes a long time to produce.
