Question

Presenter for syncing 1hr video to PPT slides

I'm looking for a solution to sync a 1 hr video to PPT slides. I came across Presenter but I seems from what I can tell only allows videos PER slide and not 1 video with cuepoints for all slides. Is that correct? Can anyone recommend a solution that I can use for this?

thanks

BTW, higher the bitrate of encoding, greater are the chances that you have dense keyframes. Thats still a guarantee but that should reduce the overlapping of missing words.

Or maybe there is a way to insert keyframes into flv files. I don't know any, but if you come across some, then please post it here.

yeah, I agree precise control of time is a problem. But, that problem exists because when flash player is asked to sync to a particular time it actually picks up the closest keyframe to that time and plays the movie from there.

The ideal solution would have been that Presenter had the capability to edit/trim video internally and play the whole of it, rather than just providing the time parameters which don't tend to be so accurate at runtime.

Hmm. I see I can edit the XML to call the same files by adding the <video> node, but it doesnt seem to be very precise as it loads each slide. There are overlaps in words and missing words even when the time codes are the same.

For example:

slide 1
<video url="video_heads_258_2_28170.flv" StartTime="0.000000" StopTime="25000.000000" MuteAudio="0" IsH264="0"/>

slide 2
<video url="video_heads_258_2_28170.flv" StartTime="25000.000000" StopTime="33000.000000" MuteAudio="0" IsH264="0"/>

Its a shame you can't load a movie with cuepoints and trigger the slides. definitely a bummer.

One other question. As I'm encoding my 1 hour video, I'm thinking of how the presentation is going to load the same video over and over again. Is Presenter smart enough to not load the same video? And if not, how will it handle calling a 1 hour movie and as I'm gettign towards the end of the video have to play from say 50 min into it.

If you would update the urls for each slide, then the browser cache would take on the smartness part (in case the content is seen from simple web server).
Although, things are a little different if the content is uploaded to Connect. With Connect the video would be streamed and hence every frame of the video would be fetched while viewing (even if you rewind the same slide).

Thx catholicon. i'll give it a try. Do I have to add the video to every slide (91 slides) or can I just edit the XML after I do the first few. Presenter is really slow it will take me forever.

Hey. Thanks for the reply. that looks really interesting. I foudn the EDIT VIDEO section of teh slide. but the EFFECTS, START AFTER and TIME (sec) are greyed out. Am I missing something?

Also, what does THV mean in your other post. I did a HELP search for it but didnt find anything. Is it really obvious and I'm just missing it.

Thx again
