Error Retrieving Frame

Hello, had the same issue with converted .mxf files.

Here is what our strategy was that seems to fix that issue:

1. Shift+Premier - delete cache files.

2. Do not open projects, just Premier and delete   All cache files through preferences

3. The most important: Delete the local user account Windows cache by the folowing steps:

Initial Steps (Enter Recovery Environment):

1. Enter Recovery Environment (If you are unable to get into the recovery environment via a menu, you can turn off your system during the initial boot when the Windows logo is on the screen and the dots are circling. Do this at least twice and you'll see the message "Starting Automatic Repair").
2. Once the recovery environment loads select "See advanced repair options", then "Troubleshoot", then "Advanced options".

Method #1 (Via Command prompt - assumes basic command prompt knowledge):

1. Click "Command Prompt".
2. Change directory to your boot drive if necessary (for example, type c: and press <ENTER>)
3. Type "CD %windir%\system32\config\systemprofile\appdata\local\microsoft\windows\caches <ENTER>
4. Type "DIR <ENTER>" and make sure you are in the right path. You should see one or more .db files -- usually just cversions.3.db. If there are no files in this directory see the addendum below.
5. Type "DEL *.* <ENTER>"
6. Reboot and test

Method #2 (Via Safe Mode and File Explorer - may require adjusting permissions):

1. Click "Start-up Settings" and "Restart" to reboot the system and get the option to enter Safe Mode.)
2. At the Startup Settings screen press "4" to boot in Safe Mode.
3. Log into your administrator-level account.
4. Open File Explorer and browse to %windir%\system32\config (example: c:\windows\system32\config)
5. Gain access to systemprofile (you may be able to just double-click it to gain access)
6. Drill down to %windir%\system32\config\systemprofile\appdata\local\microsoft\windows\caches
7. Delete all files inside caches
8. Reboot and testFinally, create NEW Premier Project and import old project assets (sequence by sequence).

Hopefully, these steps will help.

If you reinstall Premier or move back to a previous version and the issue persists, the problem has to be corruption in the media file that's dropping frames. I cured it by deleting the file, running chkdsk with repair (windows), then re-importing the file and it worked fine.  I'm sure theres a disk check utility for Mac that can repair a corrupt sector.  Run that and see if it reports any disk errors, then run the repair and impot again.

In rare cases a cosmic ray can corrupt a bit on a disk, causing it to work one day and then not the next, or the disk surface starts to fail for no good reason.  SSDs are not impervious to glitches either. Since it worked for a while then quit, the original on the card is probably OK.  Hope you haven't wiped the card yet.  (I always back them up to another drive before wiping a card.)

For now I would recommend moving back to whichever version of PPro you were using, when these files displayed no issues.

So you tell me what to do now. Please help me I am having a lot of trouble.

Thanks for the detail! 

It may not make any difference, but Media Browser supports additional metadata from card-based file structures (when available), including spanning clips (>4gb). Drag-n-drop import misses that information (which means it's not likely to be involved).

> Do you import the media directly from a camera card structure, or do you move the .mxf files to other directory structure(s), first?

First Card copy in my External SSD then SSD to import my project.

> Do you use PPro's Media Browser to import the media?

No. I just drag and drop

Confirming: Every single piece of media that matches that description worked fine in previous versions of PPro, but now all display similar behavior?

Do you import the media directly from a camera card structure, or do you move the .mxf files to other directory structure(s), first?

Do you use PPro's Media Browser to import the media?

Camera - Canon XA70

Format - XF-AVC

1920*1080 / 50fps

shutter speed - 1/60

Bit rate - 45mbps

Cool!

Could you provide all available details about how these problematic .mxf files are being created? 

I have uninstall premiere pro then Reinstall But same problem
