Stuttery, Pixellated visual playback

I have posted this problem before and no one seemed to know how to fix it. I thought i would wait for an itunes/Quicktime update but that did not solve the problem so I am posting again.
When i try to watch a video file through quicktime or a video podcast via itunes the Visual part of the playback stutters, pauseing for seconds before showing the next image which may or may not run normally for a second or so before doing the same. Often the transition from one image to the next causes the image to pixellate. The sound however is perfect throughout.
What is confusing though is that i can watch video files on websites such as gametrailers.com that use quicktime and they play perfectly.
Having looked at the Show Movie Inspector panel in Quicktime, the counter reading does not run sequentially, it seems to run as if being in fast forward skipped 20-40 seconds at a time.
I have tried everything i can think of and that has been suggested to me and the problem still persists.
My drivers are up to date, Quicktime is up to date, Quicktime Alternative suffers the same problem, I have tried uninstall/reinstall.
I have an NVIDIA GeForce 7900, running Windows Vista.

I have found something of interest, http://www.geekzone.co.nz/hadders/2273 is a forum thread of someone having a similar problem that he linked to Intel RAID array. I have no idea what that is, i have an AMD Athlon and a single unpartitioned internal HDD and an external one.
But the second post made a suggestion of running the file from an external HDD, which i did and which solved the problem to an extent.
It is now a task of finding out what is causing .mov files played from my internal HDD to play in this manner. It used to play them perfectly fine untill a number of months ago.

H264 footage is pixelating on playback

Hi
Im trying to edit some .mov H264 footage in premioere CS5 but playback in Premiere is always very pixelated. I had to convert the footage using mpeg stream so the footage would work with my pc but playback in Quicktime is fine. Also when I export the footage playback is fine. I cant edit the footage because I can hardly makeout whats going on. If I click propertys in Premiere on the clips im having problems with I get

As you can see Premiere thinks itss MPEG. Could this be the problem? How do I fix this?
This is what the bad footage looks like

Thanks for any help

Right click on your monitor window and verify playback resolution is set to full.

Pixelation on playback

I cut together a short intro scene that was fairly complicated--6 video tracks overlapping at various points. The idea is to have a small picture of each person I need to show move into a spot on a larger background, a total of eight will be shown but no more than two at once. Problem is, the video comes out very poor. The titles and background look sharp but the video clips of the people talking are very grainy (and not just aliasing). For both text and video I used the motion controls in FCP (not the Motion program) so I don't see why there should be a difference. I think the problem is in the render because when I look at unrendered footage it's very clear, as it is when I watch it from the clips I imported into the bin. When I print to video and watch on an NTSC monitor, the problem arises.
Am I on the right track thinking it has to do with rendering or does shrinking the video clips necessarily compromise quality for some reason? Will the Quick Time Pro fix I've seen on this forum help and, if so, doesn't QTP come bundled with FCP (it's not on my computer...)? Could it be a hard drive space issue? Any help at all would be awesome. Thanks.
PS - All the import/sequence/etc settings are correct.

Had you not already done a print to video and looked at it through an NTSC monitor I would have suggested Shane's Stock answer #2.
I've included it at the bottom just in case you didn't actually render eveything or disable overlays and they are the culprits.
At this point I would suggest a couple things.
First try Exporting your movie as a QuickTime movie (NOT Quicktime conversion) and make it a self contained movie. This will bring all your video tracks down to one and we can trouble shoot that as a problem. Then open a new FCP project import the QT Movie you exported , drop it into the timeline and then print to video. See if it makes a difference.
If that doesn't work then my next suggestion may then be to trash preferences, repair permissions and re-boot your computer. And I only offer this becuase I have to run out to a client right now and won't be back to check your result until later tonight.
Hopefully someone else might assist you in the meanwhile.
Here's Shane's Stock Answer I referred to earlier:
Shane's Stock Answer #2: Blurry playback
ONLY JUDGE THE QUALITY OF YOUR MATERIAL ON AN EXTERNAL NTSC MONITOR, OR AT LEAST A TV.
1. Disable overlays on the canvas
2. Make sure you've rendered everything (no green bars at the top of the timeline

Video playback requires large amounts of data and many computations. In order to maintain frame rate and be viewable at a normal size, only about one-fourth of the DV data is used in displaying the movie to the screen. However, the DV footage is still at full quality, and is best viewed thru a TV or NTSC monitor routed thru your camera or deck.

Why do my photos look pixellated during playback on a TV?

Still using iLife '08 but have noticed recently that photos I use in slideshows (whether imported from iPhoto or Aperture) look as if they are slightly out of focus (or pixellated) when played back on a plasma/LCD television screen.
After building a slideshow on iDVD and then playing it on my cinema display the images look razor sharp but this is not the case after the DVD has been burned and is being played back on a domestic DVD player and a television screen.
I'm pretty sure this is to do with the difference in resolution between the cinema display and the television screen but I am wondering if there is/are a setting (or settings) in either iPhoto, iDVD or Aperture that I should be using to improve the quality of the images when they are displayed on the television screen.
I'd be grateful for any comments, ideas or suggestions.
Kind regards,
Cliff
Brighton, UK

I've noticed a very similar thing, again with iLife '08. I've created movies in iMovie and exported them as Quicktime files and to the Media Browser. They appear fine when playing them in Quicktime but appear pixellated when playing them in iDvD preview mode, this happens for both large and medium formats.
Look forward to hearing if anyone knows anything about it.

All video content pixelated during playback.

Issue: All video content (Trailers, Podcasts, TV shows stored locally, TV shows & music videos streamed from iTunes) are pixelated. HDMI Audio is unaffected as are the AppleTV menus, screen savers and photo slideshows.
*Troubleshooting steps taken:*
Checked HDMI cable connection.
Checked HDMI cable with another device.
Checked various types of video content.
Ran diagnostics on AppleTV. No errors found.
Restored AppleTV to factory conditions.
Upgraded to latest firmware.
Synced content locally.
I have no idea what else to do. Has anyone ran into this situation? What, if anything, could I do to resolve this issue?
I have used my AppleTV without this issue ever happening before as recently as a week ago. The content that I was attempted to watch was purchased from the Apple iTunes store.

Since another device worked with the same cable and port on my Vizio TV I have, the only thing could have been the AppleTV. So I decided to go to the Apple Store. 45 minutes after unplugging the AppleTV I was at the Apple Store. Then after another 40 minutes of waiting for the Genuis, my AppleTV was plugged in and worked perfectly.
The only thing I can think of is the heat from the AppleTV always being on affected the graphics card. Let's see if it happens again.

Pixelated video playbacks

Pls hlp

Based on your description, it sounds like a driver bug. I tried it on several configs (Firefox, Mac, Safari, Chrome on MacOS, Chrome, Firefox, Internet Explorer on Win7 x64). My guess is that there's an encoding error in that stream, and the hardware decoding is less tolerant that our software video stack, which is much more complex and resilient in the face of things like network and encoding errors. The hardware is very fast, but often times less forgiving.
I would continue to keep an eye out for updated drivers from Intel. The stuff available for Win7 has had a much, much longer time to mature. The quality of Win8 drivers will also improve over time, but it's a less mature ecosystem. Writing graphics drivers is an extremely difficult undertaking, and it takes a lot of time for the long-tail of odd little edge-cases to get worked out.

After Effects pausing for a second before playback

Once a prerender has completed after effects takes a second to start the visual playback. VO starts straight away. This corrects itself once the timeline has completely played through and starts from the start.
Any ideas?

As Rick says, this is a known bug with Mac OSX v10.10 (Yosemite).
See this:

AS2 noScale and pixelation issue

We are doing a number of banners for a client in AS2 using Flash 8 Pro. The version was their specification.
Now I've generated a series of PNGs in photoshop at precisely the same dimensions an imported them directly into the Flash Library.The problem is, when we epublish this to HTML it scales up about 120% and pixelates badly. I've already explored a few workarounds to varying success. Allow me to explain:
In the swf preview (Ctrl+Enter) I get no scale or pixelation issues. The render is clean and sized correctly. The scale problem is only happening in the HTML publishing.
-I double checked the code on the HTML and the size specifications are the same as those in my FLA and PSD. Identical.
-In the publishing settings I discovered that the noScale option prevented the issue, but only for the machine I was working on. None the other test machines saw any improvement in the published banner(we have 4).
-I tried embedding a noScale Actionscript directly into the FLA. Same issues as above. Only the work PC displayed the correct size, the other machines did not.
-I tried manually setting the HTML publish size specifications. Again, same problem.
What's strange to me is that the noScale only corrects the problem for the machine the project was done on. Makes me think some caching is to blame for the misrepresentation. And the HTML Publish seems to be ignoring my size specifications for the SWF altogether. Can someone tell me why this is happening?

Well it looks like I may have resolved this issue, sort of. John (owner of the tapes) let me borrow his camera for the experiment (Thanks). This is what I did with the theory that if I captured using a sony dcr-vx2000 pixelation would be reduced.
The other night (late), I pulled some hurricane Katrina footage that I had not captured yet and capture it with the canon xl2. on playback of the capture NO PIXELATION was observed at all(I watched it three times). I took the originalvtapes that I worked with last week on the wedding and recaptured on the caon xl2. Resulted in occasional pixelation. I then took the same tape and re captured it from the sony camera. Resulted in NO pixelation when playback observed on a tv and on pc screen.
Conclusion:
even though ths is not scientifically provef true or fals, I observed that to capture from a mini dv tape if shot on sony camera, you need to use a sony camera for capture. Same thingapplies with canon.
Note: Canon and Sony, please address these issues as a professional courtesy to the rest of your customers. Thank you.

Ram audio playback issue.

So I was busy trying to sync some cuts effects and clips with some music inside of after effects. when I was going to ram preview it to find the exact times in my clips where I want certain things to happen corisponding with certain beats in the music I'm using. when I ram preview and it happens that the audio plaback along with the visual playback is at a 1.5 speed (or so it seems can't be exact)
by this I mean it's not playing back in real time. like I can here the music go by faster then it should the same fallows for the visuals. it all seems to be going by faster. now this is a big issue for I need to be able to here the song and see the visuals at it's normal speed not slower faster just it's normal 1.0 speed.
what could the problem possibley be?
I'm running Cs5.5 on mac OSX 10.6 (soon to be 10.7) and I have 8 gigs of ram installed so I can't see as to how it could be my machine lagging it? even though that wouldn't make sense for I'm not lagging I'm fast forwarding... how do I fix this?

When I go to ram preview I right click my timeline and click repview ram preview then no sound comes and it play the footage at 1.5-2.0 speed not sure exactly which speed it's being played back at.
then once it's gone through what I want previewd I press space bar and it starts to play back audio at 1.5 speed along with footage that sometimes seems like it's being played at normal speed and other times not. and the info panel will switch randomely during ram previews to red and white text saying realtime or not real time.
I don't know how to turn off color mangagment for when I go to it it gives me a drop down menu of red, green blue, etc... and one other option at the bottom when once clicked brings me to a menu with nothing about turning it off.
also I have a ram preview area set up on the right of my AE (the deafult zone for it) and when I click ram preview there nothing happens the footage plays but no audio and then when I click play again it stops??
no matter what I do I can't get the audio to play at it's normal speed unless. I right click my timeline and choose preview audio and one of the 2 options beileve they are called "here forward" and "work space"
I have no idea why it won't preview right but it won't what do I need to do to fix this?
(P.S as far as I can tell it's always been like this never used AE much (more of a photoshop/illustrator guy) but now that I do it doesn't work at all right)

Pixelation issue continues......

Hi all. I just did a edit on a wedding and there was a lot of pixelation durring the edit and on the print to tape. I did use a tv for preview and pixelation was visible. Now just to fill in some additional details. I captured it usig my Canon XL2. The shoot was done by some one else using a Sony 3ccd camera of some type. The tape is a panasonic mini dv tape (AY-DVM63PQ). Is it possible I may be having a tape,player caturing stew that is the cause of the pixelation? If additional nfo is needed please let me kow. Thanks all.

Quicktime playback staggers on large HD files

Quicktime 7.6 Pro
Playback staggers and skips frames on large files (1920x1080 1.5GB. .mov files)
VLC also staggers but plays better than QT?
I have to run files through Compressor for smooth playback.
Do i need a graphics card for smooth playback?

Apple make a program "Aperture" and that program can make slide shows of your photos.
Thanks for pointing that out. Although I am an Aperture user, I use it exclusively for photo file management and adjustments and did not even realize I could make slideshows with it.
Jon:
I see you know what your saying can you help with this one same sort of thing.
Sorry for taking so long to respond. Once I read your post, I had to go back and run some tests in Aperture before making an answer.
I made a 5min slideshow and previewed it in Aperture it worked fine. So I clicked export and exported it to 1080p .MOV file (a quicktime movie file), Aperture dose not have any setting for this just click and go. The final file plays fine on VLC but is choppy on Quicktime. WHY?
1) The "slideshow" played in Aperture is, for the most part, a live "'tween" simulation of the file that will be created and saved as a QT video slideshow. The "'tween" is basically a set of instructions telling the computer how to morph two or more images and render the results to the screen.
2) "'Tween" videos can be stored as comparatively small files and were originally used to create/view slideshows but these videos had/have compatibility issues with some of the evolving apps based on the "modernized" version of QT. The process of "exporting" your Aperture slideshow tells QT to create "snapshots" of the "morphed" images at fixed intervals in time and store them as physical video frames in a real QT "movie" file (i.e., not a QT file containing photo tracks with a "'tween" track telling the media player "how" to render/display morphing data). This "real" QT file is much larger than the "'tween" file and is the basic source of playback problems on older and/or slower platforms that cannot process (render and display) the data as fast as the platform can read it and the media application is told to play it.
3) VLC and the various QT-based media players are written to function differently with different goals in mind. In some cases the algorithms included in VLC are much more efficient than those in QT and vice versa. As I am not involved in the VLC project I have no specific input regarding the actual differences that allow it to process and render your slideshows faster/better than QT. You might remember, however, that one of the goals of VLC playback compatibility is the playback of Blu-ray disc content while Apple has yet to release any BD player app based on the QT structure embedded in any version of OS X.
4) Most Aperture export options are "presets" with fixed settings pre-programmed into them—e.g., the "1080p" option created a non-anamorphic 1080p30 file using the H.264 "best" quality auto-data rate Main Profile@Level 5 encode settings. On my system, this meant my sample file had a data rate on the order of 40 Mbps. To put this in perspective, a Microsoft 1080i60 VC-1 Blu-ray disc has a typical data rate of 30 Mbps, and a typical MPEG-4/AVC 1080p60 Blu-ray disc has an average data rate on the order of 20 Mbps. Thus, if your 5 minute file encoded in a manner similar to my test, your file is trying to play the equivalent of two Blu-ray discs simultaneously in terms data throughput. And, while my system's hardware configuration did not seem to have any playback problems, my initial guess would be that your video card(s), CPU(s), system clocking, or other issue may be preventing smoothest playback through the QT media player but is being much more efficiently handled by the VLC software.
can I put the file though some other program to make it more compatible(I know it already compatible I mean, it will not run smooth on QT) with Quicktime to give smother playback?
Yes, but my best recommendation at this point would be to make your slideshows more QT player compatible by reducing the file's overall video data rate in your Aperture export. While there may not be any user options using the "1080p" selection, you can switch your workflow to the "Custom" Aperture export option and run some tests on your own system to see it it improves matters and to what extent. In case you are interested, here are the results of my tests. Recommend you download the files for testing and comparison on your system rather than playing them via the default browser plug-in.
The following sample slideshow test files were created from unretouched photos taken by my daughter-in-law using her Sony compact digital camera and can be downloaded to your system for playback test comparisons:
http://downloads.walker4.me/downloads/Temporary_files/Jul%209,%202013.mov
The above file was created using the Aperture "1080p" preset. It is a 1080p30 H.264/PCM (38.9 Mbps/1.41 Mbps) [email protected] CAVLC encoded file. The file plays fine on my system in both QT player apps. (File provided as a baseline sample comparison with your "1080p" file export.)
http://downloads.walker4.me/downloads/Temporary_files/Jul%209,%202013-Custom-B.m ov
This is a "Custom" encoding for the same sample slideshow project as depicted above. It is basically the same encoding as the file above but with frame rate reduced to 24fps but keeping the "Best" quality level setting making it a 1080p24 H.264/PCM (31.7 Mbps/1.41 Mbps) [email protected] CAVLC encoded file. (File provided to see if the data rate reduction that resulted from decreasing the number frame "snapshots" taken each second while keeping each snapshot's quality level constant plays any smoother on your system. I.e., this is a way to minimally reduce the target data rate in Aperture slideshow export work flow.)
http://downloads.walker4.me/downloads/Temporary_files/Jul%209,%202013%20Custom-M .mov
This is another "Custom" encoded file. In this case, the frame rate and the quality settings were changed. Most people seem to think exporting at the hightest possible "Quality" setting will produce the best playback results. Unfortunately this is not always the case if the final result then includes or creates new problems. Most files can be encoded using a "Medium" quality setting with little or no reduction in visual playback. Here the exported file is a 1080p24 H.264/PCM (5.72 Mbps/1.41 Mbps) [email protected] CAVLC medium quality file. (This file was included here so you could compare playback smoothness on your system when the encoded data rate is more aggressively reduced using the built-in Aperture user settings.)
http://downloads.walker4.me/downloads/Temporary_files/Jul%209,%202013%202.mov
It is, of course, also possible to use the iPhoto app to export your slideshows. This work flow also has a "Custom" export option but it allows me to access an "Eport Movie to QT Movie" option which has many additional user options. This file is such an export. In this case the file is a 1080p24 Multi-pass H.264/AAC (16.6 Mbps/0.128 Mbps) [email protected] CAVLC file with Quality level set to "High." key frame frequency of 24, frame reordering is on, and with the data rate set automatically (but could have just as easily be set to a manual limit and optimized for CD/DVD or streaming use and/or included any of the available system filters/special effects).
In any case, you can download and compare my files or create and compare a number of your own files using any of the work flows mentioned. Good luck, and let us know if this fixed your problem.

No longer can playback in camera? No connection w/ computer?

Hi all. I have had an HDR FX1000 for about 2 years now. Never a problem with it. On the 29th of September (last Sunday) I shot a wedding on HDV with the camera. Business as usual, recordings went through, no issues.
Today (one week later of camera non-use) I try to playback the tapes in my HDR FX1000 and I get the normal blue screen which precedes visual playback... but no playback, just more blue screen. The timecode is running like normal, I just cant get any playback. I then connect it to my Mac w/ FCP 7 via FW800... and the computer suddenly doesn't detect the camera (despite restarting like 4 times and trying everything I could think of).
This is kind of like a twilight zone episode going on for me as everything has always worked like normal, the camera was idle for a week untouched, and all of a sudden these problems.
Anyone have any ideas? Thanks very much in advance for any assistance.

First, if you have the camera connected to the computer in playback mode (or whatever setup is usually required on the camera), make sure the computer is seeing the camera on the firewire bus by going to applications: utilities: system profiler and look at the firewire bus.
I'm not familiar with the camera, but some cameras have a system reset option that will restore the camera to factory defaults. Worth a shot.

Pixelated tapes...please help!

Hi
Just shot a wedding, ten tapes in total but two are pixelated during playback. Other tapes from the same camera are fine. I know this is a long shot but but is there any way to retrieve the footage or is it a lost cause. Any help is gratefully recieved.
Thanks
Adrian

I have just had he same issue with a Panasonic HVX200. I though I had dirty heads but through experimenting with other tapes recorded in other cameras I put it down to a bad batch of tapes. But this turned out not to be the case. I cleaned the heads using the recommended Panasonic head cleaning tape but this changed nothing. I asked Panasonic what I should do and they told me to send the camera into be looked at. When it came back from Panasonic there was no explanation as to what the problem was but the repair sheet said the mechanism had been replaced.
The footage was blocky and pixelated especially on movement and is unusable.

TrueColor Frambuffer on a IBM ThinkPad X23 w/ AIT Mobility M6 LY

I am building a framebuffer-only system that supports video playback on my 8-year-old IBM ThinkPad X23.
For video playback, I would need my framebuffer to have color depth of at least 16 bit. (I think)
But I am running out of ideas as to how to do that.
So far I am able to achieve this:
- my logs indicate that:
/* /var/log/everything.log */
vesafb: mode is 1024x768x32, linelength=4069, pages=1
so i think i am able to get 32 bit color depth.
- but later on in the log:
/* /var/log/everything.log */
[drm] Panel Size 1024x768
[drm] fb depth is 8
this got me quite confused.
- after it boots, if i execute "fbset -i" as root, i get:
mode "1024x768"
geometry 1024 768 1024 768 8
endmode
Frame buffer device information:
Name: radeondrmfb
Type: PACKED PIXELS
Visual: PSEUDOCOLOR
Accelerator: No
- lastly, if i execute "vbetest" i do get the option of:
[291] 1024x768 (8:8:8)
which I understand means 24/32 bit color depth.
I am guessing the "pseudocolor" means that my framebuffer cannot go higher than 8 bit color depth. But I am totally a newb in this area so correct me if I'm wrong.
Please let me know if you need any other logs/information
Thank you so much in advance.
Edit: one more thing to add. when I use vbetest to test the mode above (1024x768 (8:8:8)), the screen seems to be displaying the full color spectrum...

I would like to bump this post just this one time.
If someone has experience with FrameBuffers please help me out.
Thank you.

Playhead moves jumpy in win7/vista (even in empty comp)

hello,
after switching from winXP 32bit to win7 32/64 (and vista), im having this problem with both AE cs4 and cs5:
when i start playback or do a ram preview even in an empty comp, the playhead/cti/current time indicator red line is moving in a jerky way. The Info
panel is showing that its being played in realtime and when i add footage, the video is being played smoothly as well, yet the playhead jumps.
heres a screencap of it: http://webstuff.ic.cz/jerkyPlayhead.wmv
What i tried:
- AE cs5 in win7 ult 64bit
- AE cs4 32bit in win7 ult 64bit
- AE cs4 32bit in win7 ult 32bit
- AE cs5 in vista basic 64bit on different pc (laptop with completely different hw and drivers)
- AE cs4 32bit in vista ult 32bit on different pc
- those OS instalations were clean literally with just AE installed, i then tried installing drivers, qt, windows updates but still the same
- tried changing all AE settings i could find, as well as leaving default settings after clean install
- watched everest stats during the simple comp playback, plenty of free cpu/mem resources
my hw: [email protected], p5e64ws evo, 4gig, hd4870 512
Having tried on different pc, it should not be hardware/driver related, also not OS related within vista/win7 versions and not AE version related. So the problem should be between xp and w7/vista, something is different or missing between those.
This is my first time using OS newer than XP so maybe im either missing something which i didnt need to install on xp and should have now or is this the way how ae is supposed to behave on vista/win7? Does the playhead move supersmooth for you pixel by pixel when the visual playback is realtime/cached in w7/vista?
Any help or tips appreciated

Yes everything else works fine. Im doing alot of intensive audio syncing and altho i make great use of all the various other tools for that during the finalization stages, the ability to simply watch the cti during previews definitely helps me to get general feel and ideas for positioning and rough ins without spamming markers or deciphering scrub sounds too early, i can also quickly position main keyframes during just audio previews without waiting for full video preview in heavier comps. Its small things that add up and it generally speeds my current routine up in various situations. Iam doing alot of precise sync editing in NLEs too, and its even more about the cti there so i guess i might be just too used to it and now it feels wrong when it suddenly doesnt move smooth in AE after i switched os.
I would at least like to know whether its "officially" supposed to move smooth in vista/win7 just so i dont spend all this time investigating the problem only to find out that its actually jumping like this for everyone and they just dont care. Because ive tried close to everything by now and still cant find the cause.
