Power Point Presentations transfer to videotape

    When I videotape events such as town meetings, there are power point
    presentations that are not easy to view due to too small font and/or
    too much info on one page. I thought there must be a way to make or get
    a copy of the 'power point presentation' onto video tape. I would
    continue taping the presentor's discussion and then do a 'video insert
    edit' using the taped 'video power point copy' for a much clearer power
    point screen.
    Has anyone taped this type of meeting and found a good method to
    present the power point portion onto the video recorded tape so the
    viewer could easily read what is shown?
    I'm seeing more power point presentations at meetings and less
    'slide type projector' presentations as it was most popular in the past.

    Yes, plenty of us have done this many times.

    If the fonts used in the PP presentation are too small to read when
    projected, they will be way to small to read if converted to video.

    In which case, the PP presentation needs to be redone to the proper
    fonts and aspect ratio.

    Then there are a few ways to get it into the video. PP can
    "export" its slides as Jpeg files which can be used with any NLE
    system.

    Or, the PP show can be run from the computer through a scan
    converter to videotape, or patched directly into the NLE, or
    switched live during the event, if that's an option.

    You just need to learn what's the best method for you...

  3. I have produced a great many programs where I took the
    presener's PPT file and exported each slide as JPEG.
    Then you can drop the JPEG file into the timeline of your
    video editing application at the point where they should
    appear. It could hardly be easier.

    Note Mr. Jandro's warning, however that many PPT slides
    use fonts that are too small for viewing on standard-definition
    TV.

    Also watch out for slides that have text anywhere in the 10%
    edges of the picture (i.e. outside the "safe title area").

    The advantage of the scan converter is that you get to keep the animation.
    With JPEGS you loose all of that unless you recreate it in your NLE.

    The advantage of the Jpegs is that some of the time you can
    rework the graphics to make them more readable. People making
    PowerPoint presentations break every video rule you can think of.

    They use fonts that are way too small. They use color combinations
    that are often very unforgiving in video, and the run text and graphics
    much too close to the edge of the frame.

    I find that using PowerPoint presentations are almost as much, if not
    more, work than creating the graphics from scratch. The exception
    is when you can talk to the presenter before the presentation is created,
    and convince them to take these concerns into account when designing
    the presentation.

    I am trying to do precisely the same thing, and now experimenting with
    Scan Converters. I posted a message here a few months ago and got some
    useful tips, and I have read replies to your posting too. I am
    interested in talking about this offline to solve specific issues.

    My aim is to record a whole conference in the way you describe. There
    will be many people coming to the podium, each with their own laptop and
    their own software. Although 99% of the world might use PowerPoint, some
    may not. I use Keynote on the mac, and my friends use the Linux
    operating system. So I need a solution that is device independent.

    Another advantage of this approach is that you don't need to chase
    authors for their files, in my case with a speaker coming to the podium
    every half-hour or so.

    So a scan converter that will catch anything that is coming out of the
    computer and into the projector is the solution I am looking at. Not
    being a video expert, I purchased a cs-320
    (http://www.tvone.co.uk/cs-300-400.shtml) to experiment with.

    It takes the VGA output from the computer and passes it onto the LCD
    projector via another VGA port. Then it allows the video to be saved via
    S-video or A/V. I have successfully saved via S-video onto a DV
    camcorder.

    As the experts here say, video resolution is limited, but the quality I
    get regarding contrast and color is very good.

    One problem is that as soon as the unit is switched on, the screen
    resolution of the computer (Mac OS X in my case) becomes 800X600, which
    is too low. I am assuming a higher spec scan converter will allow a
    higher resolution. Any advice on this appreciated.

    Another way of getting more resolution might be to record in HD. I
    intend to video the conference using HD. I wonder if there are any scan
    converters that produce HD output. Have not found it so far.

    I create titles for some of my live band videos using PowerPoint and my
    laptop. The laptop has an S-Video Out connection and the headphone
    jack. It's simple enough for me to connect to my miniDV camera with
    those options. I simply run the PowerPoint presentation as a Slide
    Show and record it to tape as it runs. It's really simple and the
    results are pretty satisfying.

    I would go along with what the others have said. PowerPoint is a pain.
    If it is possible, you could instruct presenters to use the proper
    fonts and to obey safe areas. But I'm sure this is difficult if not
    impossible.

    I used Camtasia as well as scan conversion on a project that contained
    PowerPoint.. The Camtasia was far superior. The scan conversion was
    muddy and blurry. Don't know if it was a problem with the scan
    conversion but it was not worth a darn.

    Exporting to jpegs will certainly work but you will lose any
    animations.

  9. One trick I discovered to help with the video safe area is to take the
    resulting video slide show and convert it to AVI, then reimport it and
    use the MOTION filter to zoom the picture down to about 80%, then
    surround it with black fill. This is easily done in Premiere. I don't
    know about the others.

    The trick I use for that is similar. I put 2 copies of the video or still
    on the timeline then squeeze the upper layer by as much as needed
    allowing the edges of the lower copy fill out the edges.

    If the background is a solid color or simple gradient, the edges
    will hardly show.

    If you export to jpeg, then go to video from there, will you get a
    better result than going straight from a scan converter? If so, why? Are
    you not looking at the same video resolution at the end?

    Going to jpegs was not an option for me, because animations were used
    extensively. I believe exporting to jpegs does result in a better
    image than scan conversion. We just did not have much luck with it. We
    were using a solid Sony converter. But, as I said, the colors were
    muddy and text was blurry. I may be that the scan converter was not
    set up correctly. Another guy was running it.

    I gave a lot of thought and investigation to this and for me Camtasia
    was the way to go. It is not without problems. Uses its own codec
    which seems extremely slow and costs $300.

    PowerPoint is a pain to convert. Avoid it if you can. If you can't
    Camtasia works best for me. My $.02. Your mileage may vary.

    I don't think so, because I want to catch the higher resolution of the
    movie before it is turned into video. I don't think this device would
    give me any higher resolution than an SD video.

  14. Yes, same resolution. But in the case of JPEG stills on the
    computer, you have a great deal more power and sophistication
    in doing the scaling, conversions, etc. than in a cheap scan
    converter hardware box. Of course if you are using high-end
    scaling and conversion hardware (like the Folsom equipment
    Mr. Jandro has mentioned), you are likely to get equivalent or
    even better results.

    Of course you can always do some manipulation of the Jpeg images. I am
    currently working on a lecture presentation where the woman used about
    a dozen different fonts, many too small and a number with really bad
    color choices. The worst is a title page that is black letters on a
    dark red background. Even with a large font, it is close to unredable.

    The thing that gets me, is that she has given the talk previously and
    should know by now, that some of it barely readable to the audience. In
    this case it was made worse by not being able to fully darken the room.

    I'm fortunate that the shows I do are of such a calibre that the PP
    is done professionally, by people who understand the concept.

    Macs do that. Windows computers will not change their resolution

    You'll need to force the Mac's resolution back to what you want.
    Yes, the Sony DSC-1024HD scan converter will ouput HD for recording.
    There may also be others.

    As I said earlier in the thread, I did not have luck using the Sony
    scan converter. Muddy and blurry. Could this have been a problem with
    settings on the machine?

    Smile!! Would that it always happens the way you describe. The words I
    hate to hear are, "Oh, he's bringing his own. He'll have it on a disc (on
    his laptop, etc)". Or, the speaker will use the PPT he always uses for
    these presentations. I can assure you that no matter how blue the blue chip
    company there will be speakers that 'like to roll their own', often on a
    schedule that precludes intervention by a qualified PPT designer.

  20. Scan converters come in prices ranging from under 100 bucks to over six
    thousand. I have access to some at each end of the scale, and for the
    ones at about a grand and up, you do get what you pay for, in terms of
    superior qality, better scaling, superior flicker-compensation for
    where the lines are too thin. My guess about your Sony is, if it was a
    high-dollar unit, then you may have had the flicker compensation turned
    up too far. It reduces flicker from parts of the lines and text that
    are less than 2-3 scan lines thick, by applying a dither or blur. A
    little of that goes a long way. Then too, too many generations of
    digital/analog transfer will take their toll as well.

    As to preserving the cheesy powerpoint animations, there is not one
    such powerpoint provides that you couldn't do with better quality
    motion and resolution in your NLE program; it's simply a matter of
    taking the time to break the graphic down into the same elements, then
    applying motion paths and perhaps rendering, depending on your system.
    Yes, it takes more time, and you have to gauge whether the extra time/
    money is worth the additional quality. Sometimes the project doesn't
    rate the effort, that's hard for us to bear, but it's true. You may
    want to cook them a steak, but they are only asking for tater tots, and
    a good chef gives the customer what they want. Save the steak for the
    next client with better taste. If a PPT file is particularly bad, and
    I have the luxury of time, I do a cut/copy/paste of the textual
    information into a "real" CG program. Other times, I will just go back
    thru the file and tweak the slides to increase the font sizes, color
    scheme, and add drop shadows on the text wich seems to help a lot with
    readability.
