Glitchy, moire pattern artifacts after exporting h.264

I just exported an h.264 1080p video and got these strange glitching artifacts at random places in video. They hapen for about 1-2 minutes and then go away.
I checked the timeline and could find no pattern to the glitches.
Attached are a few snaps of what Im looking at.
Im exporting at the correct framerate.
Im using vimeo's preset for 1080p video.
I upped the bitrate from 5mbps to 6mbps. (vimeo had it at 5)
Any ideas on what went wrong? Should I make the bit rate higher? Do the target and maximum bitrate need to be the same? Or should max be slightly higher?
First time Ive had this happen...

The only way I know of for artifacts like that to be introduced is during shooting. It's a factor of the details in the scene the the resolving power of the camera.

Computer shuts down after exporting H.264 from mts file

My computer shuts down after trying to export a H.264 file from a .mts file. I did this with no problems a few days ago, twice! This time line is longer, about 6.5 minutes. I have a I 5 processor, a gtx 660 graphics card and 8 megs of ram. I exported audio as a wave file and added those to the timeline. In the events panel, I get a message: "file importer detected an inconsistency in the file structure of audience_end_short.wav. Reading and writing this files metadata (xmp) has been disabled". it said the same for another short bit of audio, .wav file. I thought maybe there was a over heating issue, but to no avail. Do I need to get an I 7 processor? Please help!

sorry about the spelling! Still going. About the driver issue. I was updating Geo Force drivers and my friend said to revert to the original install, which I did a while ago. That helped, but obviously didn't cure it. Wonder if I should do the same for windows updates. So although I'm still rendering after 2 hours, perhaps the new user acount will get me through this. So strange that I was able to render/export the exact files the other day. Like I said, this mts clip is longer by a minute. Plus, I got rid of the wav files that had a meta data issue. Thanks for helping me everyone. I'll keep you posted. But I do believe an I 7 processor will at least help in the speed department right?

Stair-stepping artifacts when exporting H.264 426x240 video for web

I'm trying to export a 16:9 video clip for web using H.264 compression at 426x240 resolution from compressor using square pixel aspect ratio. No matter what bit rate I set it at -- 600kbps-6,000kbps I still get these really jagged edges. Even though my source is DV, the original file does not have anything close to this; also I have never had this issue before. One other thing to note is that if I export at full resolution H.264 -- 640x360, I don't get any stair-stepping.
Here is a frame grab of the video with the problem:
http://salsunproductions.com/misc/crapy_artifacts-h264-frame.jpg
You can download a video clip of it here (data rate is around 600-700kbps):
http://salsunproductions.com/misc/crapy_artifacts-h264.mov
I'm also noticing some sort of horizontal lines in the artifacts?? This is progressive scan footage shot on a DVX100B 24pA (and captured properly w/2:3:3:2 pull down removal, the original file doesn't have this)
Any assistance would be greatly appreciated. This is getting really annoying having to export huge files...
PS: I'm using Compressor v3.0.2

It could be some scaling artifact. Make your stream progressive using frame controls (stay away from the best setting) and that should help.

Red color clips after export to H.264

Dear friends,
I am very new to try use Color. I sent seq. from FCP to Color, changed some clips use Color FX, and than back to FCP.
After export seq. from FCP to H.264 for web, some of the clips appeared red.
Thanks for any answer.
Libor

Do you mean red render bars or the clips are actually Red? With Color you should avoid H.264 until after any rendering. ProRes or Uncompressed are the best codecs to bounce between Color and FCP.

Distorted (interlaced?) look after export in AE CS6

I am working on AE CS6. My current footage is a .png photo of a model in plaid clothing. I need to zoom in the photo. The problem is, when I export my project, the clothing on a model are completely distorted (interlaced?). I uploaded a sample on Youtube so you can see it BUT ACTUALLY Youtube somehow converts it the way it looks quite good: test - YouTube. But on a computer, video (on clothing area) is completely smudging and flickering, I can't give it to a client like that.
Here is a picture of the clothing pattern that causes the problem:
I already tried:
- exporting to different formats
- switching project settings from 8 to 16 to 32 bit
- setting "Upper/Lower Field First" in "Interpret Footage" settings of a photo
In every case effect is the same. I also tried to export the same photo in Premiere Pro - and it looks great, only AE has a problem... I need really quick help on this! THX!

For the technical explanation and the physics behind the phenomenon, search for "moiré" and the apparent visual artifacts created by the interactions of frequencies that are out of phase. Your weaving pattern has a static frequency of white/black/white lines. The number of pixels on the video image, its frequency, is also static. When the those frequencies are harmonic, the image is stable. When those frequencies shift phases at different rates as you zoom out, there is an interaction between them that produces the moiré patterns. As Myl. says, you reduce or eliminate it not by changing the frequencies but by altering the waveform. You waveforms now are rigid, on/off. By softening the waveform into a sine wave you will reduce the interactions. You cannot alter the waveform of the video so you apply a bit of blur to the weave.

Moire pattern

Hi all:
My slot loading iMac G3 400 has developed moire pattern on right side of screen. This developed after all of the below had taken place.
Original Problem: Screen very dark; some spontaneous shut downs.
Connected a Viewsonic 17' to VGA port. Calibrated Viewsonic darker [it's a much brighter monitor]. This made iMac display extremely dark [not a biggie since I was using the external VGA]. Worked fine for a couple of days until the power was turned off in my building for 8 hours [iMac not on when power was turned off]. When power came back on, iMac would not boot -- start button would flicker, then switch off. I thought: Hmm ... maybe the battery is dead ....
Installed new battery. Wouldn't boot, but sometimes got startup sound and gray/blue, pre-boot screen, but no happy mac. Attempted to boot several ways[disconnected VGA; printer; DSL modem; Belkin powered USB hub; reset button; zapped PRAM; Command + Control down, but no luck & no longer got startup sound. Shut it down for a couple of hours, then booted successfully, but iMac screen still seemed a bit dark. Recalibrated and improved. Reconnected Belkin hub, DSL modem, but not the VGA monitor or printer[but would like to].
Would appreciate any help, specifically re. moire pattern, but general info on above also welcome.
thanks.

Reshoot with a different tie?
Depending on how much movement there is in the frame and etc there are several things you might do.
If it's the typical medium/close-up corp shot, you might just try duplicating the video to the second layer garbage-matting in to the tie and blurring it.
Or export representative frames to photoshop and from those frames build a tie overlay that you've blurred in photoshop.
Any way you do it, it'll be messy.

How can I eliminate a green rectangle showing up after exporting?

After exporting in FCP and viewing in Quicktime, a green rectangle on the right side of the Quicktime window is showing up for about 1 second at a point where there is black between two clips with fade in/out transitions. There is a slug there which I thought might have something to do with it. I tried deleting the slug but the green rectangle persists. Can anybody help me eliminate this green monster?

Nick-- Thanks so much for your reply.
CODEC is H.264.
In Sequence Settings I have the Quicktime Video Settings Compressor set to HDV 1080i60.
After rendering and saving the sequence, I click
File >
Export >
Using Quicktime Conversion. After window opens to save the file
Format: Quicktime Movie
Use: Most Recent Settings
I click "Options" >
Settings, I choose H.264, then click OK (the green rectangle appears regardless of quality setting (I tried 2 kinds: Best and Hight), (also, encoding doesn't matter, either. I tried Multi-pass and Single-Pass)
Click Size, choose NTSC 720 x 480 16:9 (using this just for a smaller file to FTP to show progress)
I then uncheck Sound and Prepare for Internet Streaming (no soundtrack on this yet), then click OK
I then click Save.
As I mentioned I tried it several different ways and each time the green rectangle shows up. I am nearing the end of this project and this is really becoming a problem. I hope you can help eliminate it. If you would like to see it I can email a small few second clip that will show it.
Thank you again--

Quality not the same after exporting movie made up of jpg images

Basically I made an animation sequence on Autodesk Maya and rendered the sequence as 2000 jpeg images each representing 1 frame, put it in one folder and on Adobe Premiere imported and dragged the folder into the timeline to make a moving image so in other words my video is made up of hundreds of jpg images.
Now on the editor it all looks HD and fine but when I export it via file > export > media, in order to match the sequence to the screen I must click on 'match sequence settings' which will snap the whole movie into the window rather than have it widescreen and once I do this I can't modify anything else such as codec, etc (codec is automatically set as MPEG -Frame and the output automatically is mpeg), is this normal? Why is it mpeg ajnd not avi...
So once I export the video with these settings (image uploaded) the quality is ok but not as good as what I see in the Premeire editor, why? What can I do to improve the quality?
On the other hand if I don't click on match to sequence settings and personally customise the paramaters such as avi, I use max settings for many things but after exporting my picture quality actually goes worse compared tomatch to sequence settings? (which has less parameters)
Why is this happening, all my jpeg images are high quality 720p and I should just be able to export it as normal...
I am trying to make a cut-scene to get into Unity so the codec is important as well.
How can I make my video best quality as possible being mpeg or avi? What settings do I need to play with?

Maybe I misunderstood, but did you actually put 2000 still images on the timeline? If so, there is another way. Go to Import and find your folder, and select only the first still in your sequence, then check the box at the bottom of the import windows that says "Numbered Sequence" or something like that. This will import the stills as a "video" clip.
Regarding Export, don't check Frame Blending or Max Render, the first being for a change of frame rate and the latter being useful for a downscale of the frame size.You are doing neither.
Also, never use "Match Sequence Settings". Leave that unchecked, and then choose whatever format YOU want to use for the export, whether .avi or H.264 or whatever.

Media Encoder will export H.264 720 but not 1080

I'm on Windows 7, using Premiere and After Effects.
I've installed updates for the OS, Quicktime, and Adobe applications. I've, opened Premiere under a different user, tried holding shift and alt on opening Premiere and uninstalled Premiere and After Effects. I even tried taking the Media Encoder directory out of the applications directory, then reloading Premiere and After Effects (no joy). The Media Encoder directory didn't rebuild itself.
The problem is specific to exporting H.264 in 1920x1080. It doesn't matter if it progressive or interlace, or any of the other variables, up or down. 1080 fails and 720 will export.
Does anyone have another suggestion for me to try?
Thanks in advance.

I was able to uninstall Media Encoder by uninstalling a long list of CC applications; Prelude, InDesign, Flash, After Effects, Premiere, Speed Grade, and Photoshop. In addition to uninstalling the applications, I did a search on my drive for any file with "media encoder" in the name or directory and deleted them. That search, by the way, was the only way I was able to confirm how many applications were connected to Media Encoder. There was suprisingly little on the subject in the Adobe library.
When I reinstalled Premiere, Media Encoder came along with it. Media Encoder is now working again.

Black text on white background has horrible glow after export & viewed on TV.

I'm wondering how to correct a glow that develops around black text after exporting. Black text is on white background of course.
Export settings:
H.264
HDTV 1080p 24 HQ
I've checked of 'use max. render quality' as well as 'render at max. depth'
If someone could help, that would be greatly appreciated!

If you want to try the contrast change.
In Titler ..make the White Fill less than full white. ( Color Picker Fill) 235 to 245 should be fine.
I would not mess with the Black and you should not need to Key line anything with Grey.
But maybe you did not make this text in Titler.
If not..you need to make the changes in original application. eg PhotoShop.
What TV is involved in viewing this?
How does the Text look in the PPRO Monitors?

Poor quality on movie after exporting it from Premiere Pro CS5.5

Hi!
As a part of my bachelor thesis in industrial engineering, I am making an animation that shows how different types of water turbines work.
The animation it self, I've created in a program called Autodesk Inventor. From Inventor I get an uncompressed video. This video is usually not possible to open directly, but when I convert this with FreeMake video converter, it works
Conversion in FreeMake:
From:
RAWVIDEO
1280 * 720
16:9
663,554 Kbps
30 fps
To:
. Avi, mpeg4
1280 * 720
16:9
3283Kbps
30fps
The video looks great now, but now when i have finished editing the film in Adobe Premiere Pro CS5.5 and exported it, the lines are very blurred and bad. I've attached a picture showing what I mean. I have tried many different settings in Premiere, but i cannot get it any better.
The picture on the left is after exporting, the image on the right is after converting it in FreeMake Video Converter.
Have tried with the flicker removal, but with poor results.
Does anyone have any tips on what I can do?

Thank you for the warm welcome
Yes, the video from autodesk is uncompressed avi. These files are impossible to import in Premiere, and i cant open them in either VLC or WMPlayer.
After a conversion with FreeMake VideoConverter they are possible to import, and they look very good in VLC.
My Sequence settings are:
Editing mode: HDV 720p
Timebase: 29.97 frames/second
Video:
Frame size: 1280*720
Pixel Aspect ratio: Square Pixels (1.0)
Fields: No fields (progressive scan)
Display format: 30fps Drop-Frame Timecode
Audio:
Sample Rate 48000Hz
Display format: Audio samples
Video Previews
Preview File format: I-Frame Only MPEG
Codec: MPEG I-frame
With: 1280
Height: 720
Maximum bit depth and Maximum render quality is checked.
I have tried with a variety of export settings, but my current ones are:
Output:
Format: Quicktime
Video Codec: H.264
1280*720, 29,97 fps, Progressive, Quality 100, 48000Hz, Stereo, H.264
Aspect: Square Pixels
Render at maximum depth
Depth: 24bit
Use maximum render quality.
One thing I find quite strange is that i have to short clips at the beginning, which both seem fine.

After exporting, the sound in some areas goes crazy

So like the title explains, after exporting the sound in a couple of areas goes crazy, like static. I tried twice, still the same result.
NB: I exported in H.264 in Apple devices 1080p, MBP retina 15 inch 2.6 GHz i7, FCPX 10.0.8
Thank you

When in FCPX, the sound works fine (in mono) but when exported in H.264, the sound becomes static.
I recently had a similar problem, with Final Cut playing the audio fine but in the exported file the sound was static. The source of the problerm was that the audio was just slightly less than 48 kHz. After using Compressor to transcode the media with audio at 48 kHz and importing the transcoded file into Fianl Cut, the exported audio was fine.

PDFs dull in Acrobat after exporting from Indesign - again

Hi folks,
I am aware of a previous post which discussed this issue which was apparently resolved, but it appears to have reared its ugly head again. The problem - since updrading to Mavericks and the Creative Cloud, pdfs in Acrobat are very dull after export from Indesign and it is not a transparency blend or Indesign issue. I understand Adobe blamed Apple for not updating their colour management software and the reply from Adobe was:
"We have found the root cause of this issue and are in process of providing a fix. Once this is done, we will test it to make sure that it works as expected and will release an update patch for all our users."
I am running the latest version or everything but it appears to still be a problem. I have also uninstalled Acobat XI and tried earlier versions without success. I have a print job to send off tomorrow and I am very nervous about how this will print.

Sorry about that, I apparently forgot to attach the file; have done so now.
The method I'm using for creating outlines is simply to use the "Create Outlines" command under the Type menu within InDesign. Then I create my PDF files by using the Export command under the File menu and choosing the PDF/X1a option. 99% of the time I get perfect results, it's only when I try to make outline type that I encounter this problem. You'll clearly see the artifacts in question in the example attached.
I don't know whether or not the press would have printed these artifacts, as you suggest, since no printer has been willing to execute a file that shows any anomaly in the proof process. I can't say that I blame them.
Hopefully you will see what I'm talking about and can recommend a solution, though I like your idea of simply giving them a properly executed file and then telling them to get a life. It hasn't worked so far, as I unfortunately deal with a lot of Neanderthals around here, but I suppose it's worth putting forth again the next time this issue arises. It will.
By the way, no print house of my choosing is this far behind the curve, if at all. These cavemen are always printers who have long-standing relationships with my clients, and for whatever reason (generally lowest cost I'm sure), the clients think they hung the moon. We, of course, no otherwise, but it does it profit a designer to tell his client he or she is crazy for using a printer who is a decade behind the technology curve.
We cowboy up and seek solutions, eh?

Stuttering playback after export

Hi,
Sorry if such a question has been answered elsewhere but I have looked around for the past few hours and been unable to find an answer. However I am new to Adobe Premiere Pro (and video editing in general really) so perhaps I am missing something fundamental.
My basic problem is that I have created a video which plays fine in the Premiere preview (I have CS4) but after exporting it, the video becomes very stuttering and jerky. To be honest I'm a bit unsure of a lot of the technical terms etc but i'll try to provide all the info that may be of use.
I own a Sony HDR SR10E camera and so my orignal video files are shot (to my knowledge) in 1080i 1920x1080 25fps PAL AVCHD ... (I've probably repeated myself there or something). I am trying to put the video on youtube/vimeo and so have read to try to encode using the H.264 codec, at 1280x720, 25fps, trying to deinterlace it (didn't entirely understand what that meant but read that if you choose "None(Progressive)" under "Field Set" AME would automatically do it. I've tried a number of variations of the settings but every time after it has finished its very jerky etc.
I did try exporting it as a f4v file and the jerkiness had gone but i'm not sure if you can use this format to upload to youtube/vimeo etc, and anyway I don't understand why the h.264 codec is causing this problem when it all plays fine in premiere itself.
If any more info is needed, please say. I'm sorry if i'm making some massive error but although i've spent the last 8 hours trying to understand all the technological terms and sort it out myself I haven't been able to and any help is very much appreciated!

i have the exact same problem... i used all the same settings as I did in CS3 but the h.264 output is ALWAYS choppy. I even used the program "gspot" to make sure all the settings were EXACTLY the same, and they were... but anything output in cs4/adbone encoder comes out choppy. It's not a framerate issue, it's not a problem with the source files (projects in cs3 work just fine).
I am so frustrated at this, mainly because I can't open my CS4 files in CS3 and I *need* to encode in h.264. Output to other formats like WMV work fine, but unfortunately the place i upload my videos rejects the files i upload, even though they look OK on my computer.
very frustrating, I have no idea what to do. I've tried everything in project settings as well as encoder settings but the problem still exists. All my old movies, encoded in CS3, all playback flawlessly. Again, every single setting is the same, and I have applied the Premiere update, as well as the encoder update without any luck.

Premiere CC export h.264 with artefacts

Hi!
I am very disappointed how Premiere CC export h.264.
Every time exported movie have artifacts.
Every time in different places.
I have delete all cache, changed nvidia drivers., finally removed all nvidia drivers and expored without them.
The result is - always artefacts - like colored squares on video or
like this
http://savepic.net/3898131.htm
Premiere cc 7.01
Nvidia gtx-660
Sequence-match export-1920x1080 25p 16Mb CBR.
Footages Not spanned MTS from Sony Nex-100
Effect - fast color correct.
What can I do? It is impossible to work!!!
Update.
Just export to lagarith from Premiere
The result is also with artifacts.
http://savepic.net/3879699.htm
Then import lagarith avi to media encoder and export to h.264
And what I see - there are new artifacts.
http://savepic.net/3882771.htm

This is exactly my experience with Premiere CS6 and CC h264 export.
The artefacts I had are not as bad as you show in your pics, but always exist in every export.
Now, I'm using UT-codec to export and convert it without artefacts with TMPGenc x264.
