Corrupt render files

Can corrupt render files cause artifacts like small square white blocking?

Yep, seeing it on footage that has been rendered on the edit suites I was working in at uni. Capture Scratch footage(raw captured footage)seems fine. Artifacts appear on canvas and external monitor. Monitoring via firerwire 400 port through mini dv deck on ext monitor. Working from an external firewire drive on a lacie pci firewire 800 port. Uni runs fcp 4.5 with OSX 10.4.2.
Brought drive home to work on my system with fcp 5 artifacts still appearred until I reconnected them to the captured files and did a re-render. The artifacts have dissappeared, i think. I have saved a copy of the original to work with fcp 5 so i still have the original to work with at uni on fcp 4.5. I need to be able to work at uni as well as home.
Do you think this problem stems from corrupt render files? To begin with I thought it might have been a tape problem but tapes play back clean, the clean captured raw footage seems to back this up.
cheers for help

Corrupt Oracle9IDS Files

Trying to download Oracle9iDS from the following page:

But after downloaded all files and following the directions, double clicking on the exe file opens up winzip which said that is it not a valid zip file. In addition, the file size of the file1, file2 and file4 are not 100MB. We are using Windows XP and IE to download.

Render File Offline; Project in a Loop

I was rendering a complex part when FCX stopped and said a render file was offline or something. It was so many steps ago, I forget exactly.
Eventually, I had to force quit FCX because it "froze up" on me. I went back to the autovault and got a slightly earlier version before all this started but now if I try to render that same part, FCX stops with the message "La Cie 250/Sequence 2 Op-FIN-0000015d" Render file offline. I had to force quit again because the program won't let me go anywhere.
Am I going to have to trash preferences, repair permissions and restart again? Just had to do this a few days ago. If so, what is the problem? I try not to have too many apps open at a time, do things one at a time, etc.
Any help MOST WELCOME!!

See if you can play the material using Opt-P without
rendering.
Sorry. . . . .what does "using Opt-P" mean?
Look in the capture scratch folder in
column view and see if there are preview windows for
all your clips. If any show up with a generic icon or
the preview is a generic QuickTime icon the file may
be corrupted.
There seem to be files all over the place in the folders where I designated what was to be the destination for the scratch disk. (I wasn't 100% sure about how to set up the files for the scratch disk because I had to transfer all the project files from one external hard drive to another when the first drive died. I was so afraid of losing all the work that I did what I thought best at the time. Have been a little afraid something like this might rear its head.)
Tom, I don't even know how to begin explaining to you what is where in that external hard drive.
This may be too much for a discussion group question.

Missing Render Files / Problem Exporting Quicktime Movie

Everything was going great on my 21 minute project.
I had exported it to iDVD via a Quicktime movie and it looked great in widescreen format. It worked perfectly.
Now, for whatever reason, when I load my project, I get a message saying the Render Files are missing. I am unable to locate them anywhere. I had them stored along with my project on an external firewire 400 drive.
So I press "continue" without finding the missing files.
Now when I export my movie, it appears 4:3 with gray vertical bars on the side!
When I view the project on the canvas, it looks perfect as 16:9. Everything looks normal in FCE.
Did a render file get corrupted or something? Is there a way to delete all the "old" render files and tell Final Cut Express to re-render my entire new project? Would that solve my problem?
Any help is greatly appreciated!

I did what you said and the "exported" file says:
Kind: Final Cut Express Movie File
Under More Info it says:
720x480 Integer (Little Indian) Timecode
Total Bit Rate: 30,313
Why am I trying to export?
Before I ran into trouble, I would export my FCE project using the Export Quicktime Movie command.
I then used iDVD (set to 16:9) to burn to DVD.
It worked perfectly before.
But now, all of a sudden, the same project always shows up at 4:3, whether played in Quicktime or when burned to DVD using iDVD set to 16:9.
The version of FCE is 4.0 and the version of Quicktime is 7.4.5
Thank you again for trying to help me!

Missing Render files, won't play, General Error message

I have Final Cut Pro 5.0.4 on my Mac 1.8 Ghz Power PC G5, using Mac OS 10.4.10.
I just opened a Final Cut Pro project and got a message that several render files were offline. No idea how that happened, and I couldn't find them to reconnect. Now, when I try to play the video, it stops and a "General Error" message comes up.
I tried re-rendering the whole thing,and reconnected all my media files, but it still won't play. Any ideas on how to save my project?

There are just too many possibilities for us to start guessing. Try searching for GENERAL ERROR and MISSING RENDER FILES, both topics get posted often so you'll find several suggestions and possible causes. However, not many people bother to close their threads around here so there's no way to know if any of the information we passed on was of any help.
FCP 4 and 5 had the odd super-power to make files disappear as if they had never existed. General Error often indicates a corrupt project file so try to open one of your AutoSaves.

FCPX Crashes On Open- Render File Problem

Hello-
Right now I cannot open FCPX. I've been working on a 15 minute project with a moderate amount of effects.
Tried to edit today, and after opening, quits after trying to render.
Ran Pro Maintinance Tools which generated this crash report:
Effects Rendering
This crash appears to have occurred while trying to render effects on a clip. Possible causes for this include corrupt or unsupported media, a bad filter, a graphics card issue or too many filters applied to a single clip.
Suggested Actions
Use Corrupt Clip Finder to check for corrupt media.
If you are editing with long GOP media (H.264, HDV, MPEG-2, XDCAM, WMV, etc), consider letting Final Cut Pro X transcode them to ProRes for better performance.
Consolidate filters where possible. For instance, if you have multiple color corrections on a single clip, try to achieve the same colors with just one filter.
Remove third party filters from clips, or use Plugin Manager to disable them completely.
Make sure you are running the latest version of OS X.
Relevant Line

I've deleted every render file.
I've deleted every thumbnail file.
I've trashed all preference files and caches.
Deactivated all filters within FX Factory.
No corrupt files found in Events or Projects folders.
I've uninstalled, and reinstalled FCPX 10.0.4
I've updated the OS to 10.7.4
My external LaCie Rugged has only two folders on it, Events and Projects. The entire drive is for one project.
Nothing. Crashes on open.
I'm completely out of ideas. Anyone who can help me solve this will have a slave for life...or certainly my deep gratitude.
Thank you.

This line from the Pro Maintainence Tools crash report seems to suggest it's crashing when it tries to render a "retiming" effect:
0 com.apple.Flexo 0x0000000100cc12ce -[FFEffectStack(Retiming) retimed] + 30
But I don't have any third party retiming effects applied, which means it might be crashing with the native FCPX retiming trying to render.
How could I possibly get at a built in effect to disable it? I have many clips retimed on this project.

Getting a Rendering Error "No Video in File" and now corrupted video file

I've been working with some video footage in Final Cut that I recorded directly to my hdd using adobe Onlocation. I used the chroma key filter on it and then added an animation clip from After Effects, in the form of a .mov file to my timeline. When trying to render my timeline I get the "no video in file error."
I used the render manager and trashed all the render files, then I manually searched my hdd and trashed any other render files I could find. Still getting the same error message. Gave up and decided to start from scratch except that now my original video file that I recorded with Onlocation is corrupted and I can't preview it in Quicktime nor play it in Onlocation. It also imports into final cut as a white screen.
This is the only copy of the file I have (I know, stupid me right?) so any help or suggestions would be greatly, GREATLY appreciated.

Thanks so much for your suggestions, the File Salvage option from digital rebellion worked!! Good as new!! made a backup and going to attempt to complete my project, but any ideas on why adding the AE clip to the timeline caused the corruption of the video file in the first place?

Render files disapearing

Lately I have been having issues with quicktime exporting. When I need to export I go to "export using quicktime conversion" (in this case) or occasionally I just use "quicktime movie". In the past I was able to export this way and then take the files into media cleaner 6 and batch compress them into windows media. Recently, if I attempt to batch compress, I get a message stating that following:
"The movie file "sequence 1-FIN-00000003" cannot be found. Without this file, the movie cannot play properly."
For the past few weeks, if I export one file and go directly into media cleaner, the one file will process fine it was only when I tried to export multiple files, only the last export would compress properly.
Today, I am trying to export "using quicktime conversion" and I am getting that message on the file BEFORE the export. It refuse to export the movie because it cannot find this file. I don't know why this started happening, I can't figure out any settings I have changed or conflicts that may be arising.
I tried throwing the prefs away and that hasn't helped.
I am working on a G5 with dual 2 gig drives, using FCP4.5.
Any ideas?
Thanks

What is happening is the program is looking for render files that seem to have disappeared/ become unlinked. This can be the result of corrupted FCP preferences or moved scratch locations.
* Download and run FCP Rescue. Just Delete (trash) your preferences for now.
* Verify the location of your scratch disk and if necessary change the it to the apporpriate drive. Once set, don't change the location.
* Delete all your render files using the Render Manager. Don't worry, any that are needed will be regenerated.
Good luck.

Corrupt audio files

i'm 3 months into cutting a short film and have noticed that every once in a while some of my music tracks (in aif format) seem to get corrupted. The head of the clip is sometimes not accurate. Almost as if it randomly picks up a few notes or seconds into the original piece of media.
Does this happen after multiple dissolves and renders have been added and taken away?
It's a little frustrating as many of my edits are music-driven.
(i.e. the film would be very boring without the time spent on the music cues).

I have the exact same problem and was actually going to post my own forum on this.
I've had issues with .aiff or .wav audio clips mixed with other layers of audio. When the Aif/Wavs are rendered the first time they are usually fine. But usually if a change is made and it needs to render again FCP seems to merge the two render files together; even being visible in the waveform. Other than listening to the cut and hearing a hit in a song that isn't supposed to be there, there's no way of telling it's happened.
It's a huge headache because everything I cut is to music. I wind up having to check each section of music to see if anything funky popped up. The only workaround I've found is to keep old sequences available so I can just paste in the non-corrupted audio.

Disappearing Render Files

I finish working on a project, render, save and close. When I reopen the project some, not all, of the render files disappear and need to be re-rendered.It doesn't always happen, and I've only noticed it happening after the Mac has been powered off for a while. It's not a big problem but it is inconvenient. Any help is appreciated, as always.
Thanks,
Frank, Cranford, NJ

Others may have a better answer...all I can tell you is I've seen this happen from time to time, no particular reason...same with corrupt files...etc...'it's all just ones and zeros'..poor little buggers must just get tired...
I just re-render and move on.
Kevan
EDIT - follow up to Bogie's query...for me, they've always just disappeared...I've tried reconnecting, searching manually..just gone, oh well. You could tell me to trash preferences, but frankly, I've only done that once in two years, just for kicks....just work it out and move forward.

Changing Render Files, Capture Cratch, Audio Scratch

Okay... I just got a new Lacie External 1.16 TB Hard Drive. (I only have an 80 Gig normal one, and it's full.) I've looked through the manuel, (I probably missed somthing) But, How do i put my Final Cut Express Render Files and Scratch Disks on my External drive? I don't want to mess anything up.

for video work it has been argued that having journaling on can possibly affect performance by slowing things up as it has to write changes to the disk although possibly not enough to make any perceptible difference. Some believe that this could add to any cumulative effect resulting in dropped frames. It probably won't make much difference unless working with uncompressed material.
IMHO, any unnecessary slowdown in performance is surplus to requirements and whereas ordinarily it is a good idea for journaling to be enabled in any other drive, on a media drive for video work it's simply not necessary as any final cut video file being worked on at the time of a crash/power-cut/drive failure would result in an unusable corrupted quicktime file.
Having said all that, I've worked with journaled and non-journaled media volumes and not noticed any difference!
(But then again, I've also worked on G4 imacs with 512MB of RAM and capturing to the system drive via a canon camcorder daisychained thro' an external FW drive with no problems - I must've trod in some lucky s*t! - but then the good Lord gives and takes away - I also live in Barnsley and support Leeds United!)

Corrupt Dock File?

Hi,
So on my dock, I have my Applications Folder on it to use as a shortcut, but just recently, it started to display two of every application. See my picture:
I also have my Downloads Folder on my Dock. When I drag things from the Downloads folder into the trash can, nothing happens. But then when I click +Show In Finder+, it shows the file as deleted.
So it seems my Dock is not refreshing or something? So what I did to fix it was just remove the Applications and Downloads Folders from the Dock, and drag the Applications and Downloads folder from my hard drive to the dock. But everytime I log back in or download something else, the problem will arise again.
Do I have a corrupt dock file? I didn't want to try messing with that until I consulted +Apple Discussions+ first.
Thanks, Alex

if recreating those stacks doesn't help try resetting your dock preference file. delete the file /users/user/library/preferences/com.apple.dock.plist and enter the following terminal command
killall Dock
your dock will be rest to the default. see if the problem goes away.

Project cannot open: "Searching for Movie Data" in render file

My feature-length project suddenly stopped loading today, pausing at 47% to complain that a bunch of render files are missing, and that "this movie cannot play without the file..." I've seen these error messages when trying to open Quicktimes that refer back to files that no longer exist, but not when trying to open an FCP project file. My autosaves are giving me the same problem. The render it lists is "Rough Cut" something or other, which refers back to sequences I haven't used in weeks.
I've done the usual fixes: restarting, throwing out preferences. I ran FCPRescue. I opened a blank project and did a Render Manager dump. I did a Render Manager dump earlier today (as part of my workflow), but didn't have any problems at the time. I don't know how to get around this, and I don't know why those files are supposedly missing.
There's an earlier post about the same problem, but he didn't find a solution. Thanks for any and all help!

It sounds like you used a reference quicktime in your project and the media that the quicktime referenced is deleted or that the system has some how or other lost track of it. This can be a tricky problem to fix. Andy's advice may get you up and running, but you will still be unable to work with the problem quicktime. I always try to export selfcontained qt's because of this potential problem.

Error -32810 occurred at The FieldPoint server initialization failed. Possible causes: 1. Missing or corrupt configuration file; 2. Failed to create callbacks. : FP Open.vi

I have two cFP-2120 RT controller. They both have NI-Serial RT2.5.6, DataSocket for LV RT4.2, NI-VISA 3.6, FP Drivers 5.1.0, FP VI Manager 3.1.0 LV RT 7.1.1 installed. But one same vi can run on one controller but not another.
the error message got when it runs on another controller is "Error -32810 occurred at The FieldPoint server initialization failed. Possible causes: 1. Missing or corrupt configuration file; 2. Failed to create callbacks. : FP Open.vi"
I wonder by what it is caused?
Thanks

Hi Matthew,
As mentioned previously, this KnowledgeBase article may be of some help. Also, if your code is being run on an embedded controller and then a network controller (not embedded), you will need to run the program differently. On the embedded controller, you should deploy your VI in a Project Explorer or programmatically (as described here.) However, you do not need to deploy the program to a network controller, but simply run the VI.
I would also suggest creating a new .IAK file. Do you still see the same error? Also, double-check that the software installed on the controller matches the software installed on the host PC. If you have any file paths associated with one FieldPoint controller, ensure that you are changing them to match the second controller.
Please keep us posted on your troubleshooting steps. Have a great day!
