Discussions concerning Premiere Elements version 1 - 4.

I'm working with HDV pulled from a canon hv 20. I've put all the video onto the timeline and did my edits. When I preview before render it's fine, but after a render certain clips are completely black. There's no effects applied to any of the clips. The other curious thing is that the clips show a re red line when dragged onto the timeline? not sure if this is normal. (first HD project)
I'm using Vista 64 bit
any help appreciated.

When you restart the program, do the same frames remain black?
I wish I were creative enough to write something witty here.

Yes PE has problems with time stretching MPEG material. You see the same problem if you time stretch standard MPEG 2 video... usual solution is to convert to DV-AVI. Not sure what you can do if it is high definition MPEG2, apart from exporting as uncompressed AVI and time stretching this.. however the files will be huge.
If you drag HDV MPEG2 to the timeline of a HDV project there should not be a red line above it, have you selected the correct HDV project preset?

Paul, couldn't one then convert the uncompressed AVI to a DV AVI and so reduce the file size (if necessary)?

Hi John, not if he wants to maintain the media as high definition... by exporting uncompressed the video can be maintained as high definition.

Yes - silly me. Overlooked that HD bit.

I bet not... This may have been due to moving the project over to my new quad core system. Now that I think of it I think of it I think I had Canon preset specifically installed and these new presets would not be on my new system... Thanks for nudge Paul... bet that's it.
