Strange artifacts in slide show crossfade

One of my course attendees had a strange problem on her iPad.
During a crossfade from one state to another (as a tabbed panel)
the overlayed elements (some texts) appeared with a slight ring
of strange jitters around it. See for yourself, I took a screenshot:
Has anyone else seen this error too ?
It disn't show in the Desktop Viewer.

We get this artifact on Pan Only Sliders before they have been dragged out from the right (also on iPad 1)

I recently updated iphoto 11 and now I can't view my photos in the iphoto library. Screen is blank, but photos will show if played as slide show. What's going on? ? ?

On Friday, October 28th I updated my iphoto 11 because I received notice from Apple that I should do so for better stability in the program.    Today I opened I photo and found that although all my events show they are present and the number of photos in the library appears correct, when I click on an event to view the contents, I get a black screen.   I am told there are no photos in the event.   When I return to the iphoto page it again shows all my events with pictures of the photos in the event thumbnails and the number of pictures in each event.    I can not actually view these photos individually.      Now here's the strange part, when I select an event thumbnail and right click, I can choose to view the event as a slide show, complete with music and special effects and it will play normally.   But no way can I view the event photos individually.     I have one event that claims to be empty, no photos in it, yet when I click on that event all 346 pictures pop up for individual viewing, but will not play as a slide show.    I am totally confused and want my iphoto put back to normal.
Has anyone else had this problem?
How do I uninstall the update, or failing that how do I get my photos back? ?

Hi Liz,
Sorry to hear you are having a similar problem. Last night I went to the tool bar at the top of iphoto, clicked on "File", then clicked "Browse Backups" in the drop down menu.    I have an external hard drive that is set up to Time Machine.   The Browse Backups opened the iphoto pages in the Time Machine. I selected a date one day ahead of the day I performed the now infamous update, and it showed my iphoto library as it had existed that day.   I then clicked "Restore Library" at the bottom right corner of the Time Machine screen.   Roughly 2 hours later my iphoto was back to normal.   When I opened iphoto there was a message saying I need to upgrade my program to be compatible with the new version of iphoto(version 9.2.1). I clicked "Upgrade" and within seconds it had done whatever upgrading it needed to do.
The only glitch in the restoration was that it restored the library as it appeared last week, so I no longer had photos I had imported this past weekend.   I simply went back to the Browse Backups in the drop down menu, when Time Machine opened I selected the page showing my pictures from this weekend and again said to Restore Library.   Roughly 45 minutes later the library was restored including the most recent photos.
I am now a happy camper.
I don't know if any of this will be of help to you because your email says you are having trouble with photos imported after the upgrade was performed.   Have you had any pop up notices when you first open iphoto, that tell you you need an upgrade to be compatible with the new iphoto?     If so have you clicked "upgrade"?
Good luck Liz, if you have Time Machine running as a back up to your library, maybe you wil be able to get help there, by following my instructions above.   Otherwise,   good luck with your investigations.   I'd be interested in hearing how you make out.

Can I mimic a 'slide show' of stills and videos with this technique

I want to be able to mimic an old fashioned slide show on a Blu-ray disk, except that each 'slide' – I'll call them items – could be a true still, or a still with pan/zoom, or even a short video. Whatever a particular item is, I want to click a button and the show advances to the next item. If the next item is a video, the video pauses on the last frame when it is finished.
Just like the old magazine full of slides, imagine a folder full of items – some may be stills, some videos. After importing into Encore, setting up the navigation and menus, and then burning to Blu-ray, I want to be able to play them in sequence at the press of the Enter button.
I'm pretty much a novice with Encore, and to save spending more time reading the manual, I thought I'd ask if I can mimic a slide show in Encore with the technique described below. I got the idea from page 152 of the PDF manual:
The buttons on a menu are the primary navigation tool for the viewer. They control how the viewer steps through the project. Each button in a menu must lead to another menu, a timeline, a chapter, a playlist, a chapter playlist, or a slide show.
My limited experience with Encore is to set up a series of videos on a single timeline, and generate one menu with a "Start" button on it. When the Blu-ray starts up, the Start screen appears and stays there until I press Enter. Works well.
A slide show of stills using buttons only
So I thought: to generate my old-fashioned slide show (ignore videos for the moment), I would use the buttons themselves as the stills, taking my queue from the quote above: "Each button in a menu must lead to another menu…". My slide show would consist of jumping from one menu to the next. This leads to my first question:
Q1: Is it possible for a menu to have a full-screen button, call it the Image Button, that is actually the still image that is desired to be shown? So the viewer sees the Image Button, thinks it's the image (which it is), but it is actually a button. When the viewer presses Enter, the button activates and goes to the next menu which also happens to be the next full-screen image. The viewer is jumping from Image Button to Image Button, with the buttons filling the screen and being the actual images.
A slide show including videos
To include a video in the slide show, the destination when Enter is pressed would be a timeline with the appropriate video. At the end of this video, the navigation would lead to a menu which has an Image Button of the last frame of the video. The effect is that the video is paused on the last frame, waiting for the user to hit Enter to advance to the next item (still or video).
If there is an easier way to mimic a slide show of stills and videos, please let me know.

Stan – I posted 3 years ago in the Keynote Forums (I'm on Mac) about this sort of thing, knowing that eventually I would want to do it. The answer came back then that Keynote might have problems. So I've recently posted again about Keynote, but no responses as yet.
I expected problems with Encore and welcome some of them. Overcoming problems is the best way to become intimately involved with software.
I'm glad you asked why I don't just use Powerpoint (or Keynote in my case). Now's my chance to clarify my thoughts:
Macs do not upscale very well. Sometimes I may want to show part of a DVD. I've tested playing a DVD on my iMac versus on a Oppo BDP93, fed to a BenQ W7000 projector throwing a 3 metre image. There is an obvious difference in image quality because the Oppo, being hardware based, can interpolate in real time as it scales from 576p (PAL) to 1080P. DVD Player on my iMac simply magnifies the image, resulting in obvious pixellation.
Dissolves and complex effects in Premier challenge any software based h.264 player. I don't like to see decoding artifacts, for example, during a dissolve while a part of the image is also reducing in size, spinning, and disappearing into the distance. An extreme example, but an effect I used once. From my reading of blu-ray player reviews – and from my limited testing – all blu-ray players can easily handle the highest bit rates from a blu-ray disk.
I don't have a laptop so I'd have to buy one. I'd rather spend the money on a dedicated player if that route turns out to be suitable.
I don't trust computers for a presentation. Too unreliable. When I was showing multiscreen audio visuals in the 1980s (4-6 projectors), I always had a backup Tascam 4-track with me, back up soundtrack on tape, back up amp, and a backup slide projector. Even had a backup amp in the car. Speakers, well, if one failed I had two there anyway. With digital, to feel comfortable, I'd have to buy a second laptop. A good quality, backup Blu-ray player can be had for $100. And yes, I do have a backup W7000. I don't trust digital projectors either.
Running a presentation from a laptop always looks amateurish to me. Someone hunched over a tiny screen, fooling around with Windows or OSX. And usually it's all mirrored on the big screen for everyone to see. I'm never impressed. I want to replicate a cinema experience as closely as possible. Darkness, the audience hushed, and up comes the first image.
Any suggestions about automatically linking a whole heap of menus?

Premiere 7.2.1 strange artifacts

I have these strange artifacts in several files, with latest premiere cc version (see images): artifacts appear in premiere as well as in after effects, but they are not visible if same file is opened in bridge (or VLC player). These files are .mov encoded by Resolve. In previous premiere versions they didn't show any artifact.
Could you kindly give me some advice ? Thank you !!
premiere cc
bridge

I have had similar problems in the past where artefacts would appear in PP on certain frames, but not in AE or VLC and similar. Never got an explanation to what caused it and then all of a sudden they where gone when I updated PP. And since it didn't show up in my exported files I just chose to ignore it to save my sanity :).
Now the black screen when CUDA is active is probably caused by something else. I assume it affects all videos, not just the ones with artefacts? I have seen a recent thread about problems with CUDA, NVIDIA drivers and the latest PP update, but I can't find it at the moment. Maybe Ann has some insight here...

White lines appears at bottom of screen just during slide show on Keynote.

Hi, i hope some can help me with this problem.
2 White line appears at bottom of screen during slide show on Key note 2.0.2,m i have no problems on the preview, photoshop or other program that use photos.
Another thing, the same 2 lines appears in the window of the person i'm chating on messenger.
it's very strange....

After adding audio to slide show, can we...

With the help of posts from this forum I got the audio up and running on a couple slide shows. I'd like refine a couple things, so has anybody done any of the following:
1) Can the pictures in the slide show fade in and fade out for better picture to picture transitions?
2) Can the play/pause button for the audio be changed? I'd like to add volume and maybe a percent indicator while the audio is loading.
3) Could the slide show start AFTER the audio is loaded? By the time the audio starts the slide show is usually on the 2nd slide.
4) Sometimes the audio will not loop. I think this depends on how the slide show window was closed. If the same page is reloaded again, the audio usually doesn't loop. Is there a way to re-initialize the slide show audio to guarantee it will loop each time.
5) Will the audio work if the end-user doesn't have quicktime on the computer?
I've been using this section of the website for beta testing -

It can be done, but you are asking for entirely different slideshow
With the help of posts from this forum I got the
audio up and running on a couple slide shows. I'd
like refine a couple things, so has anybody done any
of the following:
1) Can the pictures in the slide show fade in and
fade out for better picture to picture transitions?
Yes, but you will have to do extra works with javascript. There is a transition variable in slideshow javascript, but there is no control over the slide duration (it's fixed and there is now way to change it). This can cause some strange effects.
2) Can the play/pause button for the audio be
changed? I'd like to add volume and maybe a percent
indicator while the audio is loading.
Yes, change one of the arguments in QT_WriteOBJECT:
QTWriteOBJECT('SF_Soundtrack1.mov', '34', '16', '',
3) Could the slide show start AFTER the audio is
loaded? By the time the audio starts the slide show
is usually on the 2nd slide.
You can put a delay time to call QT_WriteOBJECT function, once again javascripts.

QT is preloaded in a mac, but not so for pcs; so QT needs to be installed on a pc.

Strange artifact in Illustrator PDF, only when printing via Adobe PDF printer

Hello,
I've run into a strange issue with an artifact in a PDF generated by Illustrator using the Adobe PDF printer. When I "Save As" a PDF, this artifact does not show. Using the same job options, printing via Adobe PDF creates this artifact. The object is behind the content and it's a semi-transparent box that was manipulated using Free Distort. It's behind everything so shouldn't even show up, but the outline is showing up for some reason. In the past I've had similar issues with artifacts and I changed my Adobe Compatibility to the latest version, and it fixed the issue, but that didn't work this time. Any insight is appreciated. Thanks,

I had to zoom in to see the faint lines you are talking about and they are there. As a test, try printing to the Adobe PDF printer.

Slide show reflections theme suddenly renders incorrectly

Recently I mentioned a strange appearance of a slide show I've made with the reflections theme. The mirror image at the bottom of the screen is suddenly appearing as solid instead of transparant. This only happens with a screen with one ore two pictures. With 4 pictures it shows up normally. I checked the photos and I tried using other photos, still not working. Exporting the slide show still shows this deficiency. Maybe a problem with the latest version of iPhoto 9.4.3?
Is there anyone who can reproduce this? Any solution?

As a first fix attempt Try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).
or with Lion and Mt. Lion from the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder
3 - launch iPhoto and try again.
NOTE 1: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
NOTE 2: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.

Elements 8 slide show?

I'm very new at this and made a slide show (in Elements 8) and answered the question to save it so I could continue to work on it later, and now I can't find any menu option to open it again, and I haven't been able to find it anywhere. I'm sure it isn't supposed to be this hard, so I think I must be missing something. Thanks for your help

For some strange reason Adobe puts them in the projects folder under ProgramData.
The quickest way to find them is to click on the Display button (near top right of the Organizer) and then temporarily change to Folder Location View.
You should see your saved slideshow projects near the top of the folder structure tree.
Alternatively typing pse into the search box in thumbnail view will usually find them.

1.4.1 and 1.3.1 blue screen system crash when running slide show

I have a new Toshiba Satelite X200-219 running Vista SP1. I have 30 Gb free space on C: and 4Gb RAM. Every time I run a slide show I get the blue screen of death after about 5 slides. I have swapped the original memory (2 GB) back in to see if it is corrupt memory but get the same result.
Is anyone else experiencing this or are there any known solutions?

temp6, temp7, temp8 are strange.... but because it's impossible reach these temps (+127 and +0) I think those sensors are not used or bad report data
if you think it's a overheating problem, you must log temps (sensord+rrdtool)
so you'll get the latest temps before the PC crashes

Help with some strange artifacts - N580GTX Twin Frozr II/OC

hi and firstly thanks for any assistance on my issue
I bought a new N580GTX Twin Frozr II/OC card about a month ago and I have recently noticed some strange artifacts showing up.
Basically, I get light, almost pastel coloured blue and red 'ghosting' in 3d games (eg TF2, RO2), noticeable where the background is dark. They are only noticeble when I move in the environment, but they leave short-lived (perhaps 500ms), thin outlines of the edge of the image on the screen. The image might be the edge of a person graphic or the side of a wall for instance. These artifacts don't show up in 2d screens and the machine I have is perfectly stable.
I've got the latest official nvidia driver (280), don't overclock the unit and have a corsair hx 750 ps. I have read the faq and it suggests upgrading the bios, but considering it's only a few weeks old is there any other thing I should try first?
cheers!

then retest

Slide Shows iDVD 6 And the winner is ?

Ok, I'm still tryin'. Here's what I want to do with my Mac. I want to make a DVD to view on a standard Sony TV played with a Sony DVD player. I want it to look GOOD. No image flicker AND NO SOFT Images !
I've been asked in the past, "are your expectations to high" ? My answer to that is, the software makers are saying that their slide making software is great BUT in fact, they just can't get the job done. Some one needs to tell the truth about making slide shows with computers...
Ok, what do the "big boys" use when they take a OLD black & white OR color image and use it in a TV special ? Most likely NOT iPhoto, iMovie, OR iDVD. Bow to the Ken Burns effect ? I've used it and my shows do NOT ever look as good as a Ken Burns TV special. What's his secret ? Once again, WHAT DO THE PRO's USE ?
I've been told by "the Mac pro's" to soften my problem images in photoshop first. That totally defeats the purpose. If you can't make your images look sharp and without flicker as a slide show, why bother with it in the first
place ?

I've used it and my shows do NOT ever look as good as a Ken Burns TV special. What's his secret ? Once again, WHAT DO THE PRO's USE ?
They use expensive, multi-pass hardware encoders (which includes the necessary low-pass filters to eliminate interlace flicker effects).
I've been told by "the Mac pro's" to soften my problem images in photoshop first. That totally defeats the purpose.
Here we go again. Sharpness that causes interlacing flicker problems is not useful sharpness.
All digital images have high-frequency information removed before capture. Take a look at the Nyquist–Shannon sampling theorem article at http://en.wikipedia.org/wiki/Nyquist–Shannonsamplingtheorem. To include such sharpness information in the capture process would cause severe artifacts in the resultant digital image.
First and foremost, NTSC/PAL TV are NOT a 'sharp' systems by today's computer display standards - remember NTSC has less than 640x480 pixel resolution and is interlaced. Sharpness information that causes a difference in the odd field and even field that make up a complete interlaced frame image will cause flicker as the two fields switch back and forth. The ONLY way to eliminate the flicker is to eliminate the 'problem' sharpness. PERIOD
If you can't make your images look sharp and without flicker as a slide show, why bother with it in the first place ?
I think you are dealing with the issue on a 'gut' level - 'loss of sharpness is bad'. But with digital images, this isn't realy true. Image sharpness is only useful of it can be accurately reproduced in the final digital image.
I don't know what else to tell you. There isn't any 'magic bullet'. As I told you earlier, I liked the results I achieved with some slideshows put together with FotoMagico better than some slideshows I put together with iMovie or iDVD. Other people like Photo to Movie. However, still image slideshows put together with either of these two non-Apple applications will still exhibit interlace flicker. There is no free lunch when we are dealing with an interlaced system!
Things will only get better when we no longer have to deal with interlaced video images. Sorry.

HiDef Slide Shows

I have been using iDVD to make my slide shows. But I've never been happy with the HiDef resolution playing DVD's on the TV's.
Is Final Cut Pro a software that will show a better resolution for dvd's with music and blending transitions...
If I play the images directly from iPhoto, using the dissolve transitions and music, it looks beautiful.
When I make a dvd, it must not be a Hi-Definition program because they just don't look as good.
Or is there a different Mac Program, that will play hi-def images to a DVD with music and transitions that someone can recommend...
If Final Cut Pro will work, I am only doing slide programs with disolve transitions, so I don't need anything fancy. So will previous versions of Final Cut Pro work for this? I need them to look excellent when the customer views their slide show on their TV's...
Thanks in Advance....

You're making a comparison between something transferred from film using half a million dollars worth of equipment with a desktop computer albeit a very capable one.
You are also comparing moving footage with still images truth is on DVD Movies there are artifacts its just that you don't notice them because your eye is led by the motion.
SD DVD like most compression standards has an upper and lower bitrate threshold.
DVD Studio Pro will let you set this higher than the standard setting but it could be at the expense of compatibility with older DVD players.
Essentially if you want HD all your clients need to have it too Players and TV's.
I'm sure iPhoto does look great on an HDTV but thats not really something you can compare to SD DVD either.
Have you actually tried resizing your images down to SD dimensions and creating a straightforward SD slideshow DVD you may get better results if you author everything for the delivery platform from the start.

Imported slide shows in Final Cut Express are poor quality

I just bought Final Cut Express (so it's the latest). I know this problem isn't unique to Final Cut, but when I import a slide show created in iPhoto or Fotomagico into Final Cut (or into iMovie HD, for that matter), the quality is poor. What I am trying to do is to create a movie that integrates a slide show with video, and output it to a DVD. The slide show uses "Ken Burns Effect."
I have tried outputting the finished slide show in various formats (m4v, dv) to try to improve quality, to no avail. This is even before the movie is outputted to a DVD- it's just viewing the rendered product on-screen. I'm guessing that the output from the slide show apps is compressed, then recompressed when rendered in Final Cut.
For a small upgrade price, Fotomagico has an HD output option. Would that improve things or is that the wrong tack to take? How do professionals do this sort of thing? How might I do it?

Slides never look as good on TV because you are drastically reducing the original size of probably 1920x1200 to around 720x576 which ruins the quality.
Furthermore, the fine detail is likely to jitter and shimmer due to interlacing artifacts.
You can reduce the jitter with the De-interlace filter but it will do nothing for the sharpness.
The only way you can get high quality is to produce your video in high definition and play it back on an HDTV.
Having said that, I routinely apply the de-interlace filter to all my slides and when played back on my HDTV the standard definition looks remarkably good. (But they look much worse on a CRT TV.)

Slide Show Audio Problem at Beginning of Show

Very strange occurence that I have never encountered and I'm really stumped.
I have a slideshow that was created in Encore CS4 that plays directly after the main menu. The show begins normally with two blank slides at the head end for timing and to as a fade up from black. I use cross dissolves between slide. The music begins with a video at 0 level then the video fades in behind it within three ~ 4 seconds.
Just after or as the first slide advances to the second other close to this point the music stutters for about two seconds then clears up and is fine for the remainder of the show. I felt this was some hiccup with the blank slides or some wierd issue with the audio track so I used a different one and it did the same thing at the same spot. I the render the slide show in Encore and played it from the beginning--it sounds perfect with either audio track.
I then burned the project to a folder and played the DVD from the folder in a virtual DVD player in Windows--it plays fine.
I then took one of the many disk that I had made while experimenting with different burn speeds and played the disk in the computer dvd drive--the slide show was again fine.
So only when the DVD is played in a DVD player do I have this problem. This is crazy. I have done maybe forty different slide show integrations in Encore and never encountered anything like this. Why would the show play perfectly in Encore and when the burned DVD is played in the computer but not in the a DVD settop player?
This points to the pplayer but this seems odd--what is causing it. How can I be certain it won't do it in the customer's player? It does the same thing in another player as well--but it happens to be the same model but if it were a glitch in one player it isn't likely that the same glitch would be in both. I still think I am missing something here.
Any suggestions please--I can't send this out to the client like this and tell him it's a glitch that I will fix it for obvious reasons.
Thanks!!

It sounds as if for some bizarre reason, the transition is causing the player buffer to empty out.
This happens on certain - usually older - players when sequential cells are set as non sequential in compiling.
(I had this one bite me - hard - recently, although from a different application).
Best way to check this is to go get a copy of the excellent PGCEdit (shareware) and load the compiled disc.
http://download.videohelp.com/r0lZ/pgcedit/index.html
Find the main timeline for the slideshow, and double click it. (see attached image)
The "chapters" will be listed, and we need to see these ticked as sequential playback, or seamless.
If there is no tick, add one between each track, save the disc & reburn with IMGBurn (freeware/Donationware)
http://www.imgburn.com/
For some reason, certain chipsets seem to create a gap when transitioning a chapter marker on a timeline with a single sequential audio stream when the chapter is incorrectly set to non seamless.
This may not be what is happening here, but I think it is worth a look.
