Connect 7 didn't support MP4 video content, as I recall. Another issue is that Connect rooms are using Action Script 2 (AS2) while Presenter 9 uses AS3, and the two code languages don't play well together. You don't mention if you are using the meeting application to display the presentation, but it is worth mentioning. If the presentations are stand alone, then the AS3 issue should be non-existent, but the MP4 support may be.
Is there a reason you haven't updated the Connect software to Connect 9 (or at least Connect 8.1 where the Connect application became AS3 as a whole and supported MP4 content)?
Thanks Jorma. No we are not running the webinars in a meeting room, they are being run as stand alone presentations that we've provide public viewing to via the URL.
We weren't sure that we needed to update our Connect software.... but I did assume this might have been the issue. So based on your knowledge, if we upgrade our Connect application then the video playback issue should be resolved?
I suspect that would be the case. Stand alone Content is a little less restrictive than in-meeting content, but since MP4 content wasn't supported then, I'd say it's very likely. If you have a test/development server that can be upgraded first, you can use that to verify if it does or does not change the playback, before affecting the production server(s).
Ok. I am trialing Adobe Connect 9 and have published (as stand alone presentations) several of my webinars; however, the playback issue still exists. Although there is much less of a delay and the videos play through once they start, there is still a delay which results in the slide cutting off the last few seconds of each video. I have also tried using Adobe Media Encoder to convert the videos from MP4 to FLV; but the video issues still exists. Any other ideas?
I'd look at the specifications for your videos. Generally speaking, HD media will only demand additional bandwidth, and my cause buffering/delays. When prepping a video for Presenter, I try to keep the video content near these specs:
720 X 480 resolution
MP4 and FLV content should play back in pretty much the same manner, so try those settings and see if it helps.
