Posting lots of slides with video slow playback to a halt

In our slide of about 50 slides, when we have one video slide, it plays ok, but each slide we add after, makes the captivate play slower and slower. In this case, we have about a dozen slides with video, and with all video slides in, the playback is not useable. Video is set to progressive video download and are only a few meg in size
How can we handles several slides with video?
Thanks

This sounds like a bandwidth issue.
Do you encounter the same slow playback issue if you publish the course to your local PC and play the course from your hard drive? If not, the issue isn't likely CPU-related.
If local playback is also slow, your CPU/RAM resources might be unable to keep up with decoding your video at it's current compression or size. You might need to use smaller, lighter video.
If you want to see whether or not your issue is related to bandwidth limitations, download the Charles web debugging proxy software (http://www.charlesproxy.com/download/) and use this to watch the actual downloads in progress for the videos in your course. If you see that Captivate is downloading more than one video at a time, this might explain why things start to bog down. You might need to restructure your course so that each video is downloaded separately as the user comes to it. At worst, tThis could require breaking your course into more modules.

Exporting a slide with video content

I started a slide show in keynote. A few of my slides have video content. I am trying to export my slides so that I can edit them in iMovie. It's harder than I thought. When I export it, the video content does not play because it exports a picture of the slides. How do I export my slides with video content so that it still plays when I bring it to iMovie. I already tried making that slide a Quicktime movie with no luck. Maybe I missed something in that process. Thanks for any help you can provide.

You need to export from Keynote as Quicktime using either Fixed timing (in which case you specify enough time per slide for all the builds to complete) or using Recorded timing.
You can read more about the different Quicktime Export options in the Keynote help menu: http://docs.info.apple.com/article.html?path=Keynote/5.0/en/kyntc6c24df4.html
Hope that helps.

Keynote slides with video - not linking in Ibooks Author

Hi
I have a problem with linking Keynote slides containing videos in Ibooks author. I am using the latest version of both programs on Yosemity (6.5.2 keynote, Ibooks Author 2.2 )
The keynotes is set up with ‘Links Only’ and it works perfectly in Keynote. In Ibooks author the ‘link only’ is not working and the slides just progresses to next one. Like the Presentation type was set to normal, whether or not I press the link or outside the link. The exact same keynote slides without the video doesn’t have this problem and links perfectly in Ibooks Author. The result is the same testing the Ibook directly on the Mac or on the Ipad Air (8.1.2)
To make sure about the video types I tried a number of different ones (different Mac/Ipad video conversion programs) all with the same result. The result is also the same whether it plays ‘on page’ or ‘full-screen’ in the Ibook. The videos all plays perfectly but the links are not working.
Saving the keynote to 09 seemed to solve the problem. I am new to Ibooks author …. And the whole Mac environment. But I am thinking it’s supposed to work without having to do this????
The same happened when I tested a linked keynote example from Lynda.com. ‘Ibooks essential training’. Only in the 09 version it was working with the links, when the slides had videos. This example was off course also created in an earlier Keynote version.

This is a problem that I've reported both here and via bugreport.apple.com. However, I don't think that it has to do with screen resolution (retina/non-retina). Rather, I think it has to do with setting the widget to "full screen" where transport controls cannot be used and selecting a "Links Only" presentation.
I used simple forward and back arrows set (Control-click on object) to go to next slide or previous slide. What I found was that while this works as designed when played back in Keynote (OS X or iOS) but not in the Keynote widget. The links only setting and these hyperlinks are totally ignored in the Keynote widget. Tapping anywhere went to the next slide. Tapping on the back arrow also went to the next slide,

How to go to the next slide on click during a slide with video playing? (for export QT)

Hi,
I have a keynote presentation that i want to export in QT at the end.
I have a slide 1 with just a video in full screen.
I wish i could go to the slide 2 at any time of slide 1 video.
It work in keynote when i launch the slideshow but not in QT export !!!
In qt export, the video of slide 1 play from the start to the end and i can't click to go to next slide !!!
Is it possible ?
Thank.
Toto.

i can't click to go to next slide
Using Keynote version 6.3, there is no setting in QT export to manually advance.
The only choice is self - playing.

Advance to slide with video already playing

A client wants to be able to advance to a slide with the video already playing, this is for a live presentation, normally done by rolling in video from tape and using switcher to cross fade from text to moving video.
Any solutions would be appreciated
Thanks

Welcome to the discussions, Magneticone.
If all you want is the equivalent of a crossfade, it can be accomplished quite easily.
In Keynote, video can play behind other objects, and can be set to play immediately upon slide transition. These two features allow you to emulate a cross-fade.
Set up the first slide in its final state, and take a screenshot of it at its full-size (100%). Set the transition to the next slide as "None" (the default).
On the second slide, insert your video file, and set it to play immediately after the slide transition (this is the default). Now, place the screenshot on top of the video image, align it so that it exactly matches the first slide, and give it a Dissolve build out, to run immediately (or with whatever delay you want) after the slide transition.
What will happen is that the first slide with transition to the second "invisibly", since the same image is on both. Once the second slide appears, the video behind the screenshot will start playing, and the screenshot will then fade to reveal the already-playing video. The effect will be of a slide crossfading with video.
(As is often the case with Keynote, it is helpful not to first approach presentation problems in terms of actual "slides", but instead in terms of what the effect should be. Many time you can fool the audience into seeing more or fewer "slides" than are actually used in the presentation, and this can make achieving certain effects possible, or easier.)

Presenter Slides with Video Buffer forever

We have several Adobe Presenter presentations hosted on Rustici Cloud, and the problem we have is that each slide buffers for a second or two before playing. But the real issue is that slides with mp4 video in the slide, appear to buffer forever.
These courses were originally authored in Presenter 7, and then recently opened and edited in Presenter 8 to make small changes. It appears that once the course was published in Presenter 8, the buffering issues began.
Anyone ever experienced similar and any ideas for how to fix it?

Presenter 8 changed the default setting for controling pre-loading of flash content. In 7 and older, there was no limit on preloading content, unless you set it. In Presenter 8, the default is to disable the pre-loading for Flash content (SWF, FLV, MP4). This is what is likely causing each slide to buffer and the videos to have a long buffer. You can change this setting in Adobe Presenter > Settings > Quality and it will be the option in the image below. Un check it and then republish.

Slides with graphics slow to display

In CP7 I have multiple choice questions slides with graphics in it, when I move to the next slide there is a hesitation of several seconds before the next slide is displayed. On slides with NO graphics the next slide is displayed almost instantaneously. Any help?

It could be the quiz timeline that is causing the delay.
Quiz slides pause on enter, once you 'click anywhere or press y to continue' (after feedback caption if you have one) captivate unpauses the slide and contunues playing the timeline, then changes slide.
Example:
If the quiz slide length is 10 seconds and is set to pause at 2secs, and your image is displayed for 10 secs in your timeline, when you 'click or press y to continue', captivate will play the remaining 8 seconds and then change slide.
So make sure that your quiz slide pause, and your image is the same length. (or alternatively set the slide to something like 3 secs and make sure you set to pause after 2.9 secs, that way it will change straight away once you click to continue)
E.g. make sure its like this:

I am having a very bad time with loading videos into Keynote, which I have used for 7 years in medical lectures given all over the US and the world. Yes there are a lot of slides with cine loops, but I have never had these crashes before. A

Is there anyone at Apple that I can talk to about this Keynote issue of losing sldes after saving?

Question Slide with video

Hi, I'm trying to create a question slide that has 2 videos and then a queston to display after the user has watched both videos, however, the question displays at the beginning when the slide is viewed and stays showing. There does not seem to be a Timing option to Appear After so many seconds.
Is there a way to do this

You are correct that you cannot time the captions and other elements on a quiz slide as you can with other slides. If you must use a quiz slide, your better strategy is to place the videos on a slide before the quiz question and only progress to it after watching the videos.

Problem with Video unlimited playback on xperia z1

Hello,
I am having a problem viewing a video I purchased on Video Unlimited. I* have purchased and viewed videos on my Xperia Z1 before. The video shows up in my 'movies' folder but when I click on it, it begins loading then I receive the message 'Cannot play video'.
Any suggestions?
Thanks,

Did you copy it to another storage device or from another phone or did you download it directly onto this device and then try to play it?

Issues with video/audio playback and Source window

I have some video that I am trying to import to get into my sequence. Anytime I open the video into my source window (or drag it to the timeline), the audio goes crazy. It starts skipping around and jumbling itself. When I open the video file in Quicktime on my computer, it opens and plays fine. Also, I don't know if it is unrelated, but sometimes when I open a video in my Source window, there is no audio. I can drag it to the Sequence and double click on it to bring the Sequence video into the Source window and it plays fine.
The video that I am having issues with is a .mov filmed from an iPad (not sure which iPad model). It is filmed in Portrait mode, not sure if that matters. Please let me know what other information might be needed to troubleshoot this issue.
Thanks!

Ooh. Sorry about that.
- I am using Adobe Premiere Pro CS6 v.6.0.3
- I'm sure I have the latest update. I'm using Creative Cloud, and the Adobe Application Update Manager says everything is up to date.
- Operating System is Windows 7 Professional (Service Pack 1)
- Source footage is a .mov filmed in portrait mode (I didn't record it.. Haha) on an iPad, not sure the model.
- I am getting no error messages.
- I was just dragging the video file from the Media Browser to the Source window. Nothing special.
- This is working on all of the other clips filmed from the same iPad at same resolution, etc. Also, this particular video plays perfectly in Quicktime. It's just when I try to play it in Premiere Pro.
- Other software that is currently running is standard stuff: antivirus, Outlook, Gtalk, Dropbox. Nothing that uses audio.
- I have installed K-Lite Codec pack when I got the computer.
- I have a Dell Preision T7600, Dual Xeon Quad-core processors (2.00GHz), 16 GBs of ram, Nvidia Quadro 4000 (2GB), and running off of a 256GB SSD.
- I am using the Mercury Playback Engine GPU Acceleration.
- The issue is happening on playback, both in the Source window and the Program window when I drag the video to the Sequence. It plays fine in Quicktime.

Problem with video file playback

Hi,
I just converted a music DVD file to ipod using itunes. It plays fine on my 5th gen ipod, but I'm unable to scroll through the file to the point I want to hear - it lets me scroll but then automatically reverts back to the beginning of the DVD (ie. 0:00). Is this normal and unavoidable (I really don't want to have to listen to an hour's worth of video before I get to part I want to hear) or is there something I can do about it? Thanks very much.

I have the same problem and I know that it is due to my PCI Audio driver not being compatible with WIndows 8.1.
iTunes isn't the only program that can't direct sound to the built-in speakers anymore. The obvious solution would be to update the drivers, but unfortunately Dell does not provide an updated driver for my model, so I am stuck with that.
However, saying that, only my laptop speakers are affected by this. I can use sound fine on applications where I can choose the output device and direct sound to the head phones, but for some reason iTunes does not let you choose the audio device manually.
To listen to music I imported the iTunes Library in Windows Media Player and changed the audio output using the following instructions: http://windows.microsoft.com/en-us/windows7/c00d11ba
However, I would also like to rent movie's from iTunes,
Would be great if iTunes would let you choose the output device, too, like most other applications using sound from Skype to Windows Media Player,...

Looping Slideshow with Videos. How please?

Hi
I just downloaded Keynote 09 as 08 did not support 1920x1080 Res. I'm pretty au-fait with Keynote but I'm a bit stuck with something.
I'm trying to create a looping slideshow with images and text and also videos. I want the slide show to just run on it's own without any clicking of buttons at all
The problem I have is that when I click play,the Presentation starts off fine, and shows the first few pages with static images and text, but when it gets to the pages with Video on, it plays the video for five seconds then moves on to the next slide, I don't want the slides with Videos on to move to the next one until the video has finished, how can I do this? I've looked at "recording a slideshow" but have been unable to fathom how that helps.
An answer would be much appreciated.
Thank You.

A few different ways about this. You could split the slide show into smaller sections that are withi the limits for posting and then post each section.
You could try a different encoding to make the file smaller. What settings did you use when you created and exported the slide show?

How do I get my project with video onto my website?

I just want to be able to upload my project, which is a mixture of slides with video. There seems to be multiple ways to upload, but I don't know which method to use over another and while I've tried doing so the videos don't work.
So I tried again and tried to link my videos that I currently host on Amazon S3 into my project, but it won't let me do that. Is there a way to do that? If I can't use Amazon S3, where should I host my videos? What am I doing wrong??
I'm using Captivate 7 (32 bit)
I've slides with audio added and videos embedded as a video object.
Much of Captivate is very easy and intuitive to create projects, but I want to get this up online.
Maybe I'm completely missing the point and it's really easy, but I'm now so confused I don't know what to do.
A simple guide to uploading a project would be very helpful.
Thanks

Have you tried bouncing yet? Underneath your Main Stereo Outs there is a little button for Bouncing. Hit that and a menue will open. Choose the format you want to bounce (44.1/16 Bit perhaps) and set the beginning and end point of your Song. If you setup a cycle for the whole length of the Song it will automatically take the Locators as the the Bounce In and Out Points. There is also the option "add to iTunes Library" in that menue, so choose that and later burn a CD from your iTunes library.

Have also heard that the ipad3 revamped version is around along with the mini pad rumor..too much information - lot's of confusion pls help

Lindsay,
Your iBookG4 is still a pretty awesome Mac. Like already said, it has the power to run Leopard, but it depends if you have an internal DVD drive.
Then I suppose you have to add up the cost of the OS, perhaps another 512MB RAM, iLife 08 and replacements for any favourite apps that you currently use (Leopard breaks a lot of stuff, but Intel breaks even more). Compare it to the cost of a new MacBook, which wil have all of that included and be 3-4x faster too.
It also depends on what you want to achieve with your iBook. My PMG4 still cuts it today, I still use it in preference to my new Mac Pro, It's about the same age as your iBook, and I'll only stop using it when it becomes "painfully" slow. My 1 year old son currently uses the Mac Pro (parts for a Mac Pro are easier to replace than those for a PMG4).
I think your choice is simple, if you can a cheap copy of Tiger, use that, it'll get your iPod Touch up and running. It came in DVD and 4 CD version (by request).
Leopard will work for you too but a lot of the best eye-candy requires quite a meaty graphics card and you may need a RAM upgrade and replacement software - OS9 Classic is not supported in Leopard.
