Render glitch in AE (and FCP7)

Every so often I will get glitched frames in AE, and also in FCP7 . The glitch happens when a clip is rendered. Most often, a diagonal line appears in a frame. Sometimes there are other issues, such as artifacting. The glitches never appear for more than one frame, and it is rare or more than one glitch in a single clip. The way we have been fixing the problem is to cut the clip around the glitch and re-render the affected area.
We haven't been able to pinpoint the cause. It doesn't have to do with a certain filter being used. We primarily use BCC, FxFactory, and CoreMelt plugins, and haven't seen any correlation between any one filter being used and glitches appearing. We tried the usual fixes, and just recently reformatted the computer and reinstalled from scratch. It seemed to work better for a couple weeks, but the glitch came back.
Here are two examples. I used an artist sketch filter on the video. The first glitch is a diagonal line, the second is distortion of the video/filter. The clean frame came between the two glitches.

If I've left out any information, please ask. I'm just typing as I think.

What codec are you using? What version of AE. I'm not having any issues with any of the ProRez formats CS6 and OSX 10.7 0r 10.8

Motion and Final Cut render glitch

I am having a problem with renders, The Problem seems to be in Final Cut and Motion. Usually when I bring .motn in to my Final cut sequence, though some times the glitches happen in Motion as well. When I rerender, the glitches will usually appear in a different location than the first render.
These are picts of what the glitches look like.

I am running Final Cut Studio 5 and editing HD 720p30
I will be monitoring the thread so ask for clarification as needed. Thank you.

In the olden day, when SCSI was the drive protocol, render glitches that occurred in different places on every render were usually caused by bad connections between the drives or between the drives and the computer.
Render glitches that happen in the same place each time are almost always caused by errors in the media files. Sometimes they are invisible until an application like Motion or After Effects tries to use them.

AE CS6: Render glitches with timeremap expressions

Version:
11.0
OS:
Mac 10.7.4
Source Footage:
.ai files
Problem:
First of all, we've been using this method for character animation since AE 7.0. We have had minor glitches here and there, but nothing consistent enough to a real problem. We're currently using CS5.5, and considering the CS6 upgrade.
I am filing an official bug report for this, but am curious if anyone else is experiencing this. I don't want to share my project here as it's for a TV show in production.
Starting with CS6, we're experiencing random, arbitary render glitches all over the place. Our character comps are generally two comps deep. Meaning in the character comp, we have timeremapped comps for sequences of eyes, eyebrows, mouths, etc. Inside those comps, there is a lot more going on than just an image sequence. We have mesh warp keyframes and other stuff.
All of this is controlled by various expressions that link everything to some simple master controls. I'm sure this sounds familiar -- it's very similar to the method used in these tutorials, but not even as complex.
As for the glitches, they are hard to pin down. There are different glitches depending on whether the character is continually reasterized in the scene or not, which comp we're in, etc. Really random. The problem is resolved by proxying those precomps (the eyes, mouths, etc) with prerendered sequences. This is an OK workaround for most cases, but we can't depend on it.
Thanks for any help. In the meantime we'll be sticking with 5.5.
Bryan

Has anyone had any success talking to Adobe about this?
I would really like to know if they can fix this in CS6, and not wait to fix it in the CC version. I am not sure I can convince my studio to make the plunge onto the cloud, and so we may be stuck with CS6.
I found what sounds like a similar bug described in the previous patch (11.0.2):
Fixed difference in rendered result between ray-traced 3D renderer and Classic 3D renderer when using time-remapping on precomposition layer with collapsed transformations.
If they were willing to fix this, maybe they could fix this other time-remapping inconsistency bug.

Premiere CS 5 render glitch

Hey guys! Im having serious render issues with Premiere CS5. I always
use to render the work area before the export of a session. But this
time there is a serious glitch during the rendering: The progression
bar takes an insane amount of time. Even though the Sequence is just 2
minutes long. For example: It takes 30-40 minutes to get from 90% to
95%!! The percentage number just goes back and forth. I shot a 20
second clip where you can see this weird glitch
http://www.youtube.com/watch?v=MR_TGW6hLhA&context=C4ed381fADvjVQa1PpcFP9KzFRiX7LQnV7VMzVl f1eSBV1JS7qhgg=
does anyone have an idea where this glitch could come from ?
btw: when I go directly on "export" instead of rendering the sequence,
everything works fine!
cheers

Not familiar with an issue where the render doesn't work and export does (I've always had export fail, too), but when I've had those issues with rendering/exporting, it's always been one of two problems: a) I've got a "black hole" in my video where there's a couple frames without any video in one of the tracks, or b) I've got a still image that's too big for Premiere to process.
Honestly, though, unless you've checked the box for the export to "Use Render Files" in it's encoding, there's no need for you to render before you encode. I never do, and I have beautiful results. The only time I ever render is if I need to have a smooth playback of a complex timeline involving several layers of RED material and I need to have smooth playback at 100% for client approval before the encode. But even then, I never let the encoder use those render preivew files...
My understanding is that it's easy for those files to get corrupted, so you can end up with unsatisfactory results in your export by using them.

Render (both for preview and export) takes forever

I'm running Premiere Elements 12.0 (really 12.1) in a MacBook Pro Retina running 10.10.1 (14B25)
It has quad Core i7 each 2.7 gH, NVIDIA GeForce GT 650M 1024 MB, 16 GB of ram, and a 750GB SSD disk. There are no other applications running on the computer, and there is at least 300 GB of free disk space on the SSD.
I am trying to edit HD video from my GoPro Hero 3+. I'm just loading the GoPro files using Add Media. Then I cut out boring parts, add in image stabilization and some titles, etc. The sessions typically have 6 to 8 files, each about 2GB of video. It represents 2 to 3 hours of capture. The goal is to get maybe one hour of nice video.
Previewing viewing is terrible, with video out of sync from the audio by many seconds. You can't see any movement in the video for 10 to 30 seconds. This gets better if I use the "render" button on the timeline, but this process takes 15 to 30 hours. And the improved preview speed only stays effective for a short while, as I do edits, add effects, etc. it gets slow (aka unusable) again.
Once I've fought the program to get ready to do an export, I've got another multi-hour wait. Usually this is a bit shorter than the initial rendering, since the editing process has removed an hour or two of content.
I know, these are big input files, and the resulting movies are big (a couple of gigabytes). But this is one of the fastest and most expensive laptop computers sold in the world. I'm just using a GoPro, not some fancy Red or 4K camera.
I need to have the editing process be 3 times faster, I want it to be much better, ten times faster.
I thought that quad real core with 8 threads, 16GB of ram, and a 750GB SSD was fast.
I'd like concrete answers as to how I can get there.
Are there settings for Premiere Elements that will help? Would I be happier with Premiere Pro? Would I be happier on a Windows machine with 2 or more high end graphics cards?

thanks for the reply. I'm new to GoPro and Premiere Elements, so I don't know exactly what some of your stuff is.
The video is taken on my dirt-bike, a motorcycle going through trails, woods and rocks. Its unwatchable without stabilization.
The files are all taken as a single ride, single push of the shutter, and I go off and ride for a couple of hours. The GoPro automatically switches to a new recording file when the old one gets to 2.4 GB (which is about the maximum file size for 32 bit file formats.
I copy all of the video clips to the SSD from the GoPro. Then I load them as assetts. Since that it the only disk I have, everything is there. But an SSD should be fast enough to handle swapping, file reading and writing. I don't think that you can get two separate SSDs in a MacBook Pro Retina. It has no optical drive (which you could replace with an SSD in older models)
I'm not against buying Pro if I have to, I'm cheap, and would rather not, but if that will make the workflow feasible, I'll cough up the money.
All of clips (everything) have "Motion" "Opacity" "Stabilizer" and "Image Control"
I actually have no clear understanding of what Motion does vs Stabilizer.
Timeline rendering takes 10+ hours. More if the Mac sleep mode sets in. I have no idea where the rendered files are. Whereever PE defailts them. Still SSD
What is "the Edit area monitor"? Do you mean the smallish video window above the timeline? Sometimes the video looks pretty good, other times the viewing of it lags 30 seconds or more behind the sound and timeline pointer.
I don't think I understand your comment about when to stabilize. I agree that I should be able to work and do edits, titles, etc. without stabilization, and then just turn it on at the end. Or maybe even render it for export and then stabilize that file. But I don't know how to do any of that.
Thanks
Pat

Is it possible to render the clips individually and relink- such as with Color/fcp?

I'm fairly new to Ae/ PP, and am trying to figure out a good workflow for grading (using resolve lite) Basically, I need to denoise my footage first (neat video) and then send that footage to Resolve, then back to pp. Now, this works fine with Resolve's scene detector as it can cut up the footage, but if there are any dissolves, etc, then I need to do this via xml instead.
What I would like to do is: Edit in PP. Send to AE to denoise, render (the denoise need to happen before grading) and replace the original files with the new denoised clips in pp. Then send the xml to Resolve. So far this would work if it wasn't for AE rendering everything into one clip, eliminating the cuts/layers.
Is it possible to render the clips individually and relink- such as with Color/fcp? If not, any other workflow that could work for me?
Hope someone can help- dynamic link is driving me up the wall.

Simply use Dynamic Link to send your whole timeline to AE or use AE's Premiere project import. Then once you have a working AE project, you can use scripts like rdPreCompose to create separate sub-comps for each clip which in turn you then can render separately. Still, the limitation will always be the kind of transitions you use. Essentialyl you should avoid anything that isn't a hard cut or simple cross dissolve 'cos there's no way to recreate it in AE without eating up the handle of your footage. You'd essentialyl be shooting yourself in teh foot if you jump ahead too far in Premiere and already add too much finishing there.

Parallel use of fcpx and fcp7 in late macbook pro 2011

I am happily running fcpx under Lion, however, have a lot of old projects on fcp7.
I was unable to install fcp7 under lion to the late 2011 macbook pro 17, and this might anyways be a bad idea, as it eats a lot of terabytes on boot volume.
Just want to share my workaraund, as it took quite an effort to figure out:
1) MAKE A BOOTABLE CLONE OF LION BOOT DRIVE ON EXTERNAL FIREWIRE DISK USING SUPERDUPER OR CARBON COPY CLONER.
2) BOOT FROM THE EXTERNAL LION BOOT DRIVE AND PARTITION THE INTERNAL DRIVE ON LION BOOT AND SNOW LEOPARD BOOT
3) CLONE THE LION BACK TO THE LION PARTITION
4) BOOT FROM 10.64 SNOW LEOPARD INSTALLER DISK AND INSTALL SNOW LEOPARD 10.6.4 TO THE SNOW LEOPARD PARTITION OF INTERNAL DRIVE
5) NOW BOOT FROM THE NEW INTERNAL SNOW LEOPARD DISK, AND RUN SNOW LEOPARD 10.6.8 UPDATER
6) INSTALL QUICKTIME 7.6.6 (THE LINK IS SOMEWHERE ON THE APPLE PAGES) IT SPECIFICLY NEEDS TO BE 7.6.6., NOTHING ELSE.
7) INSTALL FCP7 FROM THE ORIGINAL INSTALL DISKS
NOW YOU CAN BOOT FCPX OF LION PARTITION AND FCP7 OF THE SNOW LEOPARD PARTITION, DEPENDING WHAT YOU WANT TO WORK ON.
NOTE THAT THE LEOPARD PARTITION ONLY NEEDS 24 GB OF USED SPACE, IF YOU DONT INSTALL MOTION AND AUDIO CONTENT PARTS OF FCP7.

You dont need lion at all, but you might need an external boot disk for the preparation.
Some resellers have reported cernel panic type problems if trying to install snow leopard directly on a macobook pro IF that macbook pro originally shipped with Lion. They say, there might be a chip preventing non Lion installs.
So, I would just for safety, prepare everything on an external drive, then boot of that exptrenal drive a couple of times to be sure it works, and then clone it over to your internal boot drive.
Anyways, if I put the Snow Leopard as startup drive in system preferencies, I would be able to work only on Snow Leopard environment. Personally, I like having both, as I like studying FCPX's possiblities in projects which permit it.

If I've left out any information, please ask. I'm just typing as I think.

so what are your clip settings (select a clip in the timeline and hit command-9)? Frame rate, pixel dimensions, pixel aspect ratio and codec (or compressor) and field dominance are what we need to know. And what are your sequence settings (in fcp) or compositon settings in AE?
I'd think of 3 obvious things that might be responsible; a non fcp friendly codec like h264, mismatched frame rates and mismatched field dominance.

Preview and Render Glitches

Hello I am working for past 3 years on same system and hardware setup, till this days everything was fine. Glitches like this show up:
<iframe src="https://www.flickr.com/photos/jnatheanimal/17043805548/in/set-72157651694316889/player/" width="800" height="450" frameborder="0" allowfullscreen="allowfullscreen"></iframe>
System info:
Windows7 Professional, SP1
Intel Core i7 2600 3.4GHz
8gb RAM
Nvidia GeForce GTX 570
Adobe Premiere CS 5.5 - updated
Footage info:
Canon 5D - 25fps - works well
Canon 7D - 50fps - gives glitches
I tryed to block CUDA, in Premiere and from the icon toolbar, nothing changed. Have updated quicktime, divix h.264, but doesn't helped at all.
Do You have any ideas?

Well, I don't really have a clue. The only other thing that springs to mind is a CoDec breakdown/ incompatibility in the given environment, but you made no special mention of what footages you use (and I forgot to ask, admittedly). Do the renders go thru without any external footages (simple text layers, internally generated effects)? I would also look into the media cache and disk caches. Especially the media cache can get humungously large sometimes and then disk access will be erratic, even more so on a notebook where disk speed is limited. Use the preference options to clean it out and maybe move it to a more suitable directory than the default one in your user home directory.

Render glitches in Final Cut Pro 4.5?

Anyone else having a problem with audio and video glitches in the render files when using Final Cut Pro 4.5? I'm operating on a G5, OS 10.4.1, and 4 gigs of RAM.
-Patrick-

I recently updated the OS, and I'm running QT 7.0. This just started happening 2 days ago. So I don't think the OS is the issue. Everyone else at work is running 10.4.1 and they don't seem to be having the same issues.

FCPX and FCP7 different yet similar re: AVCHD

With regards to AVCHD, is the primary difference between FCPX and FCP 7 (or 6), is that one, FCPX, renders the prores transcode in the background, and the other,FCP7 (or 6) renders the prores transcode in log and transfer? Is it correct that neither works with AVCHD natively (Like Adobe Premiere)? Is it correct that the only difference between the two is that FCPX lets one work during the prores render while FCP7 (or 6) requires one to wait untilafter the prores transcode to begin work.

Thanks, Tom.

Win 8.1 update - sound popping / glitch in MetroTube and all APPS when scrubbing video

My phone Nokia 1020 was working fine. I then downloaded the over the air update for Win 8.1 and Cyan on Thursday 7th August from O2.
Since then I have experienced a loud popping / static noise when playing video in all apps (except StoryTeller)
Using built-in speaker:
When I play video in any App with a video scrubber and I scrub the time-line and realise the scrubber it makes a loud click or static pop.
It happens in everything including:
Mytube
Metrotube
Tubepro
Photos App (i.e Microsoft one - playing a recorded video in they all now have a loud click / static pop)
Xbox Video App (i.e Microsoft's own App)
Using Headphones:
There is no load click (It plays how it used to)
The odd bit is using the speaker and playing music tracks (mp3s etc) and scrubbing there is no static popping click it plays fine.
Video In Web Browser Fine:
Playing YouTube Videos in the web brower there is no popping / static click noise.
I have just downloaded 'xVideo' App and played a HD Music video in it and used scrubber and there is NO loud click.
Sound Glitches in Audio Clips at end of recordings in all these Apps:
Babbel - Learn Spanish
Coolang - Learn Spanish
Zeemish - Learn Spanish for Beginners
its really annoying and makes trying to listen and remember pronunciation of words difficult and frustrating. Phone was ok before Microsoft Windows 8.1 update now have this issue and issue with static build-up causing popping when fast forwarding through
videos. :( I am feed up
Conclusion:
This is software bug? please can anyone help/advise me on how to fix this and if anyone else is having same glitch with 8.1 update :(
All I can think of to fix is to somehow downgrade to Windows 8 if that's possible? :( *update its not possible using Nokia Recovery as it puts back Win 8.1.
It is a Software bug introduced in Windows Phone 8.1 update. It effects everything! including
Microsofts own Video Xbox App and
Photo App. See other people frustrations on this issue, its been going on since April!!!! please can you fix this is ruining my Windows Phone experience:

Microsoft need to fix this Video Popping urgently, I have tired to want to like Windowsphone but they keep going backwards and I am loosing faith.
If is not fixed soon i.e next few months I will never buy a Windows phone again and will recommend the same to friends and family. I had so much hope and expectation for 8.1 update :( love the Notification bar and battery icon but I can't live with
all this. :(

Hello,
You should ask in the

As the Microsoft Community is on a different platform, we cannot move the question for you.

Photoshop CS5 Video Render Never Finishes; Mac and Windows

Hello,
I've tried rendering a video using Photoshop CS5 and it never finishes. The progress bar reaches the end but the process never completes. The video is only three seconds long (it's the video rendering exercise in Adobe Photoshop CS5: Classroom in a Book, Lesson 12). A 3D postcard is being rendered. First, I tried the settings in the book, H.264, Medium (quality), 15 FPS, 700 x 700, one-pass. That is only 150 frames! It never finished. Since then, I've tried all sorts of output formats from a 70 x 70 pixel WMV file to standard-def DV/DVCPRO NTSC. Nothing finishes. My Mac Pro has 12 GB of RAM with over 8 GB free. Photoshop is at the latest update.
Now, here is the kicker. I had my students try the exercise in the lab at the university where I teach. We have very up-to-date Windows PCs in our lab and Photoshop CS5. The exact same thing happened on the PCs with six of six students, the render never finished.
I've searched to no avail for a posting about this problem. I'm stumped. Thank you in advance for any suggestions.

The serial number is platform specific. So your current serial number will only work on the Mac platform. You will want to purchase an additional license for Windows. Alternately once the Creative Cloud is available you can subscribe have one install under Mac OS and another under Windows of the soon to be current version, CS6, if you would like. You can find more details at http://www.adobe.com/products/creativecloud.html?promoid=JQPEQ.

Thought I already asked this, but don't see it. Want to know what the "Render" feature is for and how you use it.

I've watched several of the tutorials. I was able to upload a video yesterday to YouTube, but today, I made a new video, and after three tries, never could get it to upload. Kept getting an error asking if I wanted to TRY AGAIN.
As I was editing my video, the sound never seemed to work right with the video. The video would freeze, and the sound would keep going. Strange. I figured I needed to push "Render", but have no idea what it does. Can't find a tut on it.
Any help will be much appreciated. I have six versions of PS, and I have never been able to get videos to upload to YouTube except for the one I got to go yesterday. Failure today.

Big question. After you pressed the Render button and the Timeline rendering was completed, did the video portion play back better in the Edit area monitor?
Timeline rendering is just a preview feature. It does not fix a problem. It is the program telling you if you are viewing the best possible preview that the project has to offer. The program uses a color indicator line over the Timeline content to tell you if you are seeing the best possible preview.
No color line or green line = you are seeing the best possible preview, no Timeline rendering needed or available. In this condition, if you hit the Render button, all you will do is play back the Timeline content in the monitor...no Timeline Rendering. An orange line over the Timeline content is the program telling you that you do not have the best possible preview and in order get that you need do Timeline rendering. You can do that
a. pressing the Render button above the Timeline area
b. going to Timeline Menu/Render Work Area or use the shortcut for that, just press the Enter Key of the computer main keyboard.
You do not have to do Timeline rendering, but it is your window of opportunity to catch a problem sooner than later. It is particularly indicated
when for titles, effects, transitions, and non native formats.
And, if you are getting the orange line over content suggesting that you do Timeline rendering, you can select the area where you
want the rendering done under that orange line.....you set the gray tabs of the Work Area Bar to span the area that you want rendered.
Also, the process of Timeline rendering deposits preview files on your hard drive automatically. These preview fields for a SD project are DV AVI files (whether you render a still or video file) and for HD project are MPEG2.mpg files (whether you render a still or video file). You should keep watch for pile ups of those preview files if you are getting in a free hard drive space crunch.
Screenshot from Premiere Elements 11
This screenshot is from Premiere Elements 12
I could go on and on about Timeline Rendering. Do you want more?
As for the workflow problems that you are now having, have we discussed them before. I will look for any of your prior threads to see
if we have talked about these problems before.
Please let me know if you are OK with the above.
Thanks.

IPhone 5 Glitch - Text Messages and E-mails

So basically when I have any application open that uses sound, such as a game for example, if I turn down the volume within the application, when I exit the application the volume of my text messages and e-mails are set to the same level as whatever I set the volume to in the application that I was just using previously.
For example, if I go into Temple Run and turn the volume almost all the way down to the lowest setting, when I am done playing the game if I receive a text message or e-mail I can barely hear the alert because the volume of those alerts will be set to the low volume from when I was playing Temple Run. I have to go back into Temple Run and turn the game volume all the way back up again to get text message an e-mail alert volumes back to normal.
I thought maybe this was an issue with the new iOS 6, but I had a few friends test it on their 4 and 4s iPhones and they did not experience this glitch. So I think maybe it's only a glitch on the iPhone 5. Can someone with an iPhone 5 check to see if it happens to you too? If not, maybe I just got a defective phone.
Thanks,
Jesse

I just updated my iPhone 4S to IOS 6 and I am now having the same problem. I play The Sims Freeplay, but keep that volume set at 2 or 3 bars, sometimes even on mute. When I left the game, my text tone was barely audible. I messed around with the volume settings for a while, but I couldn't get it louder. Then I finally went back into The Sims Freeplay, turned the volume up to about halfway, and then exited. What do you know? My text tone is now about as loud as it used to be. I went back and turned the game volume back down again to check, and that seems to be what it is basing the text tone volume off of. It is a bit ridiculous. I am really hoping that Apple fixes that bug very quickly, because I should not have to leave my games on blasting loud in order to hear my text messages or emails. Other people have been complaining about the low text tone (or none at all) on other forums, but yours is the only place I'd seen someone else discover the game volume as the way to fix it.
