QuickTime flickering during Video Tutorials?

I've uncovered yet another quicktime bug. In order to eliminate the borderline artifacts in full screen, I returned to normal viewing mode. However, when I pressed play, it did not play at all. Instead, the progress arrow at bottom moves, the double vertical lines replace the left arrow (to indicate playback) but without playback. This is not a one time phenomenon: I was able to duplicate the problem over and over.

The thing is, I was so glad the flickering was gone, I ignored these two bugs I've just documented.

Wow, you're right. There are thin border lines on the right and bottom on my Macbook when viewing a quicktime movie full screen. I never noticed it since I too was just happy that the flickering was gone. I hope they fix this now...

Oh, and there is yet ANOTHER bug with OS X video playback. This time in the DVD player.

If you play back "fullscreen" video, you will see the same type of "border" lines evident in fullscreen quicktime playback. I only see the problem when the source is video, not film. Second, these border artefacts are only evident at the low grade deinterlace setting of "better."

PS: The deinterlace setting descriptions are very confusing. It's clear that "optimal" is meant to be, well, optimal. However, it's unclear whether Apple intends "better" to be better than "good" or vice versa. Someone was DEFINITELY working overtime (and not in a good way) when they were re-writing the DVD player software for Leopard...

I just downloaded the update 7.5. The computer just hung for the longest time before restarting. All apps were very slow to open after restart. I notice:

1. unfortunately, the odd borders in full screen are still present. I notice now they are even present when inside the controller window.

2. the video looks GREAT. I mean fantastic. Could be a placebo effect.

I am still getting flickering in quicktime with the quick tip videos.

Works fine for me.

The solution to your problem, and its causes, are probably contained earlier in this thread, which is now far too long, with far too many participants, to be of any value.

NVM, it is only when I use Opera 9.51. When I use Safari, it works fine.

I don't mean to hijack the thread but can you define flickering?

If I watch the pro videos or tutorials and do not move the scroll bar, it plays fine.
If I scroll the page down while its playing it flickers.

Is that normal?

Thanks

The behaviour you describe is normal, but might not happen if you had more RAM.

Hi, not sure if you are talking to me....

Not normal though, have been working with film/audio for years and PC for a long time.

Normally, its either hardware, software (drivers), player, et-cetera, or content.

It would not happen when I allowed the movie to fully load as often anyway.

Then I upgraded (QT Pro anyway) from 7.1 to 7.) and upgraded to 10.5.4.

Problem solved, and pages do seem faster as well. Now off to test Safari beta.
Last time I had 10.5.4 and Beta Safari, terrible GPU problems, at least now, 10.5.4 is stable and if there are problems, I can uninstall safari.

Thanks just the same.

Everyone else, make sure you update to latest Quicktime at least I am sure that solved the problem and not 10.5.2 or 3 in fact, I will test updating to quicktime on a 10.5.2 machine and report back.

peace

This issue is also happening to me with my PB and 10.4.11, so it's definitely a software issue.

I am having a similar problem with quicktime, but it also happens with other video programs. The videos look great on iMovie after importing them from my camera, but after exporting the video to quicktime or to iDVD, I get a mysterious black line that flickers. Usually it is in the same spot throughout the video. I have a screenshot--maybe this will help explain what I mean. The horizontal black line that I am referring to is above the bird's head towards the top of the screen.

PLEASE HELP! It happens every time I export a video and try to play it back, regardless of how high the quality is.

Thanks.

Potentially good news: my boss had the flickering issues on a new MacBook and asked me about it. As with everyone else, VLC could play the same movies just fine. I found this thread and read most of the messages, enough to know that there's no certain solution so far. But I did also know that there's the update to 10.5.4 from a few days ago, as well as the one to QuickTime 7.5 from before that, and so I told him to just do all the Software Updates he was offered. That was enough to fix the issue.

Maybe then either 10.5.4 or QT 7.5 did take care of the problem.

An update to this: I am a technical journalist covering this issue. My own MacBook Pro is affected by the problem, and like everyone else I have been waiting for a solution to the issue from Apple.

I now strongly suspect that the issue is hardware related, because after contacting Apple's media relations department I was asked to bring my MacBook Pro into the Apple Store Sydney for repair and lent a loan-pool MacBook Pro. The loan MacBook Pro does not have the problem at all... neither the scrolling graphics corruption nor the flickering/flashing animation/video problem.

The notebook they've lent me is almost exactly the same config as the one I had problems with too -- a 2.6GHz Core 2 Duo with the 512MB NVIDIA 8600M GT graphics chip. The only difference with theirs is it only has 2GB of RAM, whereas I had mine upgraded to 4GB.

Looking at the System Profiler info, I can see the NVIDIA chip has the following device info:


Chipset Model: GeForce 8600M GT
Type: Display
Bus: PCIe
PCIe Lane Width: x16
VRAM (Total): 512 MB
Vendor: NVIDIA (0x10de)
Device ID: 0x0407
Revision ID: 0x00a1
ROM Revision: 3212

Can someone with a faulty machine look at their System Profiler > Graphics info and see if their ROM revision or Revision ID is different?

here's my graphics card info:

GeForce 8600M GT:

Chipset Model: GeForce 8600M GT
Type: Display
Bus: PCIe
PCIe Lane Width: x16
VRAM (Total): 256 MB
Vendor: NVIDIA (0x10de)
Device ID: 0x0407
Revision ID: 0x00a1
ROM Revision: 3212
Displays:

And here are my specs:

Model Name: MacBook Pro
Model Identifier: MacBookPro4,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB

Bus Speed: 800 MHz
