So pleased this forum is here, and in need of yet more help.
I've inserted a number of wmv files intp powerpoint presentations, but am limited by the size of the clip when it plays. Quality is lost if I enlarge the files in the presentation, and pixellation undermines the quality of what I'm trying to show.
Is there anyway around this, via powerpoint, or external programs wjich might help.
Thanks in anticipation.

Hello again Iain,
so the clips are working now in WMV format?
That's wonderful news indeed.
You know whilst PowerPoint is very much a multimedia tool. In many ways it sadly isn't. As we discussed in the previous thread, it's not actually PowerPoint which plays the video, or the presentation into which your video files are "embedded". PowerPoint only links to the video files and Windows then plays them through the MCI Player.
You reach a challenge Iain when you want to play fuller screen high quality video as part of a presentation because firstly you are running PowerPoint and its ineractive slide features. Then ask PowerPoint to load and play video.
Video files will always have to be compressed Iain, unless of course they are in MPEG2 (DVD standards), in which case even then they are compressed, only that the compression is so muhc smaller than at MPEG1 levels that you notice it much less. But then you can't expect PowerPoint or any other application to play this level of quality "interactively" as part of a presentation. It would have to be played as part of a self running presentation (DVD-Rom) with which you do not interact.
This way Windows would use its resources (Memory, graphics card, etc) to play the video, and only the video, rather than use it to load and run your presentation. Then launch your video files and each time continue to run PowerPoint in the background.
Ultimately Iain, if you want high qaulity video in your presentation. There are only 2 things you can do.
- If you know the machine you will be running the presentation on, and know that it will only be run from that machine. You can experiment with the compression settings to get the best quality video that is still playable on your machine and with PowerPoint.
- If you really need high definition or DVD type quality video Iain in your presentation then I'm afraid you can't run it from PowerPoint or run your presentation as a PowerPoint presentation.
You can however use PowerPoint to author your presentation, but then you would need for example Microsoft Producer to export your presentation as a single high definition video file such as DVD, and then burn this to disk. But it won't be interactive and it will be a video file.
Producer works by allowing you to run your presentation as you would normally, rehearsing your timings etc., whilst it records your key strokes and what happens on screen. It then creates a video file of this which you can then use as the basis for a DVD or to run directly from the DVD drive.
You can "capture" your presentation in full screen DVD quality and play it back as a "film" which you narrate, just as you would a normal presentation. Only all timings and speed are predefined from when you recorded the presentation, so you would not be able to elaborate on a point or say more things, or open for questions without pausing the "film".
Outside of these options Iain, I'm afraid your only other option is to produce a "film" or to use a higher spec computer that allows greater opportunities in relation to PowerPoint and playing video at high resolutions in parallel.

Hi again Iain,
ultimately, it's the old addage. if it's not broken. Don't try to fix it.
Of course one can always optimize, tweak and tune. But at some point the physical limitations of the machine, i.e, memory, graphics card, etc., will determine more or less what is/ isn't possible to ahcieve. These physical forces themselves provide the framework that we must work within.
PowerPoint is in itself a resource demanding application, which makes our "multimedia" options even more critical in regards to file qualities, size, etc.,
I'm extremely happy that we were able to find a working solution Iain, and one that whilst perhaps not HD or DVD quality was far superior to the stop/ start/ inconsistent playing you were experiencing before.
Been a pleasure to be of help Iain, and any questions regarding your presentations, PowerPoint presentations, or with PowerPoint in general Iain, I hope you won't hesitate to ask. We'll be here to help.
Wishing you all the best so far.
