Can't finish/edit video

[robirdman1]

One of my Nikon Z7 sequences is 1.47G.  When I try to play it. the slider keeps moving but it freezes and I can't tell what is happening.  Then it turned sky blue about halfway.  This is PP CS6.  Rendering didn't help.

Moved to the Premiere Pro CS6 & Earlier forum.

Try resetting the preferences:

FAQ: How to reset preferences in Premiere Pro?

If that doesn't work, try resetting the Workspaces:

Reset a workspace

Reset the current workspace to return to its original, saved layout of panels.

1. Do one of the following:
   • Click the Workspace menu icon and select Reset to Saved Layout.
   • Choose Window > Workspace > Reset to Saved Layout.

If that doesn’t work,,try updating or rolling back your graphics driver directly from the video card manufacturer’s site.

[robirdman1]

Neither action solved the problem.  I was able to use the frame by frame button, and delete a lot of useless footage that made the smaller segments play better, with less freezing.

[Peru Bob]

What are your computer specs?

[robirdman1]

I noticed that I missed the part about the rollback.  Looked that up and saw my Graphics Card needed updating, so did that.  Might have helped a bit, but still lots of freezes, requiring stopping and starting again in sections.

What is your hard drive setup (how many, what kind, what is on each, and how full)?

[robirdman1]

This picture will show the usual basic setup. D is mostly a backup of Z.

Z is where video projects and exports are.

Y is where all images and videos are stored

W is a backup for much of Y

G is just some miscellaneous stuff.  Used to be the C drive but quit rebooting and replaced, everything reinstalled on current.

Y and W are external, the rest internal.

Sometimes I have more externals connected. I have about 16 more, mostly backups for smaller selections.  Does connecting more slow things down?

Move the images and video that you are working with in the project to an internal drive.

Use externals for backups.

Where are the Media Cache and Media Cache Files?

[robirdman1]

Using the externals sounds like it could well be a good reason for this problem, and I will definitely try moving some for a problem video that I need to redo.  However to move all my video source sequences would be a much bigger problem.  My images and videos are all organized by subject matter and are mainly of living things sorted phylogenetically.  So there are parent folders for birds, Arthropods, mammals, etc.  Then subfolders, such as Orders, Families, even to species.  Many videos don't accept metadata such as keywords, so organizing them would require duplicating the whole structure of thousands of folders, and not done readily.  Also I don't think the internals have enough space for all the video sequences.  But if the test works, this would be a good long term plan, to store and organize videos separately. 

I have to redo one that I uploaded to youtube at Accipiter cooperii COOPER'S HAWK immatures - YouTube

It has mixed sequences from both the Nikon D4 and Z7 cameras, and although it looked OK compiling and editing (as far as I could judge despite the repeated freezing), on youtube, the larger Z7 files are cropped with the bird's head cut off.  I had made an earlier video setup for the Z7 instead of the D4 and that one used both types but didn't have the problem, while this was set up for the D4.

[robirdman1]

I moved are redid the latest video that was stopping and it made a big difference.  I moved the whole 'unused video' folder to the internal drive and loaded Piping Plover sequences, of which there are dozens of Z7 files and also playing without stopping, so definitely alleviated the freezing problem.  How do I check the media caches.  Thanks!

How do I check the media caches. 

By default, both the cache files (in the Media Cache Files folder) and the media cache database files (in the Media Cache folder) are stored in these locations:

Mac: /Users//Library/Application Support/Adobe/Common

Windows: \Users\<username>\AppData\Roaming\Adobe\Common

NOTE: By default, AppData is a hidden folder. Check this tutorial on how to access it: How to Find the AppData Folder in Windows 10 - YouTube

You can change the media cache location under Preferences > Media in Premiere Pro

FAQ: How to clean (delete or trash) media cache files?

[robirdman1]

So they are there in the C drive.  Should I move?

[Peru Bob]

Normally, I would say to move them to a separate, fast, internal drive, but if it's working OK for you now, just clean them as necessary.

[robirdman1]

Should I have deleted the media cache as well as media cache files.  Each 41,000+

[Peru Bob]

Yes.  It will be recreated if necessary.

[robirdman1]

Though the video does not freeze as before, there are some momentary hesitations and jerkiness in some places.  Does the choice of scratch disks affect, and any suggestions there?

[Peru Bob]

Try adding another fast internal disk and put it on that.

[robirdman1]

I ordered a 7200rpm 6T drive.

The latest video, where is sometimes shaky from shooting at a long distance from a vehicle at some Whooping Cranes, is proving awful to edit, because it is hard to discern which jerkiness is from vibration and which from the stop-start playback.  Not only that but I have changed the scale of one sequence from 100 to 130, 150, 200, and 400 and it doesn't change. Spending hours reducing a 17 minute compilation.

[robirdman1]

The exported video showed a lenght of 20 minutes, when the edited sequences totaled less than 7.  I reopened and found that the work area went far beyond the sequences and wanted to pull it in, as in other cases, but it has no orange end handle to grab and pull in, no matter what magnification I use to try to get to the end.

[Peru Bob]

Try double clicking here:

There is also a keyboard shortcut to designate that the end of the work area bar is o be placed where the Current Time Indicator is.

Go to Edit > Keyboard shortcuts to find it. Mine is different than the default, as I have customized it.

Answered in your other message Can't shorten video

[robirdman1]

While things were going well for a while, now I have a problem when I create a new project with Z7 video files, and press spacebar, nothing happens, and in the buttons, there is no play button.  If I close the project and reopen it is playable, though wtill jerky or hesitant in parts.
