HD-editing in VS X4; Very much noise in previewwindow

Post by Jan-61 »

I edited the project-properties to HD, according to the hints Trevor gave in this topic:

http://forum.corel.com/EN/viewtopic.php?f=1&t=43801
As a work-round----Change the project properties to use 1920 x 1080 and your images will be 1920 x 1080.

Settings-Project Properties (Alt+Enter)
Edit File Format ---Microsoft Avi Files
Edit
Avi Tab
Compression to Microsoft Video 1 (there may be others you can use—Div X ??)
General Tab
Frame Size---User Defined to 1920 x 1080

Ok now the screen shots should all use the larger image size.
(I had also to choose 25 fps in order to get PAL Video, as we use this in EU)

It works, but ! get a awful noisy, snowy preview.

I discovered that the noise dissappears there where a title is underneath in the timeline.
And it dissappears also when:
- played in the Clip-playback mode or when moving the slider underneath the previewwindow while a clip is selected
- a filter has been applied onto a clip.

So it hasn't do to with the performance of the hardware I guess.
What then can be the point of this issue?

Putting on Smart Proxy didn't work at all (there were even not proxyfiles generated in the assigned proxyfolder!)

Regards, Jan.

EDIT: Also the snapshots were noisy. I did the following workaround: via trackmanager I created a second title-track. I made a title -- black point with size 1 point and dragged it in the corner of the previewwindow. It is hardly visible. I stretched the titleclip underneath the entire project. For this it works, the playback looks good now but it is occupying the entire second title track.

Yet the question is: is there a better way to resolve this?
I also enlarged the pagefile to twice the RAM-amount (initial value 4096 Mb; maximum value 8192 Mb).

Hi Jan

Not heard of this problem before?????

So if you start a new project, leaving the project properties as default.

Add video files from the library, the samples provided by VS do you still see the “snowy preview”.

Now add your own video files……..any difference

Have you installed the patch, Service Pack 1 available from Corel.
