VS takes 90 seconds to load

[jparnold]

I have noticed lately if I had a video library containing a lot of clips selected when I shut down VS the next time I start VS it can take 90 seconds to finish loading before even a project is opened
It seems that this long delay is only if the library selected on starting VS is particularly large (ie contains many clips) and it is a video library.
When it is a small video library or a library containing a small total 'filesize' eg. an audio library or image library then the delay is minimal. It is as if VS is reading every video clip in the library on startup.
Is this normal? Is there any way around it apart from trying to remember to select a smaller library before closing VS?

I didn't know you could select a library when you open VS. How do you do that?

In any case, I seem to have another side of your problem. You get the long delay when you reopen VS. I presume that the first time you open VS, it is quick. For me, the first time I open it in the same boot session, it takes approx. 90 seconds, so we agree on that time. But if I close it down, and then later reopen it in the same boot session, then it opens in under 20 seconds. This behaviour is, moreover, consistent.

I tried to explain in my question that I select the library BEFORE I close VS and then when I start VS later the library, which was selected before I closed VS seems to be automatically selected (well it is displayed on the right of screen) so I can only assume that VS 'remembers' which library was selected/open the previous time it was used.

If that library displayed doesn't contain many clips and/or they are not video clips (which are large if filesize compared to others) then the startup time is quick and if not it can take 90 seconds (in my case) with that blue rotating circle displayed. Yes the startup time is shorter I just tested and it took around 8 seconds instead of 90 if I restart VS and I have NOT shutdown my PC. If I have shutdown my PC and startup it can be 90 seconds.
There seems to be a cache? used perhaps but that cache will not be there if the PC was shut down before restarting VS. I do not understand why VS (it seems) needs to read all files in the library. 90 seconds seems an eternity to wait. I will have to ensure I make sure I have selected a 'small' library before shutting down VS.

Strangely after PC shutdown and start VS with a small library 'preselected' and then I select the large video library it does not take 90 seconds. It's really crazy and not understandable.

VS does automatically open to the last folder open before closure, can't say that I have noticed any difference in load time depending on folder size

[jparnold]

This is crazy. I have just done a proper test and times how long it took VS to start and be ready with my large video library selected..
Restart VS without shutting down the PC - 11 seconds
Shut down PC, restart PC and WAIT until Windows etc to fully start (no 'waiting' icon), Start VS - 14 seconds.
Now I must state that the extra long VS start with the large video library preselected took around 90 seconds (I did not use any timing device but after the first 2 or 3 times it happened I then SLOWLY counted from 1 and got to around 90 so it was an estimate but still much longer).
Maybe something else was running in the background such as my virus checker (checking entire system) to slow things down although I have never noticed noticed any delay in any other software startup.

I just don't get it but better mark this as solved.

Well its (the long delay with VS starting up).
I had been using my PC fro all sorts of things this morning especially using Blender a 3D object creation tool.
I just decided to use VS and I counted the number of revolutions of the 'busy icon' (the blue rotating circle) after VS displayed its screen and my large video library was preselected. I counted 111 revolutions YES 111 revolutions and I think one revolution takes about 1 second. So I waited, not very patiently, 111 seconds after starting VS before I could use it. I had NO other applications running at the time and it was probably 4 hours since I first booted up my PC.
It's so annoying and it doesn't happen every time so its not easily repeatable.

So I waited, not very patiently, 111 seconds after starting VS before I could use it.

What does Task Manager tell you that VS is doing, e.g. disk, network, etc?

Good thinking. Next time it happens I will check Task Manager.

[jparnold]

Well this I think tells all. I used Task Manager when I just started VS again and when it once again took forever to start.
Note the DISK ACTIVITY. All the time while VS was loading (around 111 seconds) the disk usage remained high. What is VS trying to read? All I can think of is every video clip in the video library. And why?
Very annoying.

When you run X10 are you starting the program from the desktop icons
Or are you selecting a VSP that will open X10 then launch the project.

Check your library folders to make sure all clips are intact and that non require a relink

[jparnold]

Thanks Trevor,
I rarely if ever start VS from a vsp file and certainly not recently.
On checking all the clips displayed in my video library I found one for the entire rendered project which is 4.6gb in size. Maybe that caused problems?

I have NO IDEA why there would be an 'entry' in the video library for the entire rendered project and have no removed the thumbnail.

Is it normal when you output a project to video that an entry be placed in the video library as I certainly didn't do it and wouldn't want it anyway? I output my rendered video to a location nowhere near where the video clips used in the project are stored.

[asik1]

Any rendered project will be placed in a library.
It's been so for ages

Personally rarely use the video library so I've not experienced this problem. That said, I see the same slow startup when opening a large VSP. The reason for the slow startup is because VS has a file integrity checker that calculates a hash value for files in the library and the active VSP and stores them in a database. The checker is run dynamically to calculate and compare the current hash values of files in the library and the active VSP against those in the database. If there is a mismatch then VS knows that a file has changed or is missing and alerts you.

You have created a large number of folders containing a large number of files per folder (see image). In TM, you can see the CPU and disk activity as VS's file integrity checker is at work (see image). This checking takes time, so if it's a nuisance, then reduce the number of folders that you have created and the number of files per folder. Of course, the other option is to simply wait for the file integrity checker to finish it's work.

I have NO IDEA why there would be an 'entry' in the video library for the entire rendered project

VS always creates an 'entry' in the video library once a VSP is rendered, however, you can delete these entries.

P.S. Your profile lists "Hard_Drive_Capacity: 2048Gb mix". If it's a HDD, then you might want to switch to a SSD as that will speed things up somewhat.

Thanks
I have been using SSD drives for some time.
Yes I am aware of the fact that a large project can take a long time to load and realise why and so accept that.
The delay I experience is that VS can randomly take 111 seconds just to get to the point where I can do anything. My somewhat large project (which I open once VS completes its startup) takes longer to load but that is understandable as it is quite large (edited rendered file runs for 26 minutes)
I take your point that VS may do integrity checks along the way but this startup time randomness maybe be because the video library (which was the last one used of the previous time I used VS). I state this as if the last library used was a small one or one which doesn't contain many clips (in file size) I NEVER have a problem with startup times.

I have just re rendered my project after some minor modifications and the thumbnail for the rendered project was added by VS to the currently selected video library (I selected a small video library before the 'output). At least that is know now and I must remember to either select a small library before rendering and/or remove the unwanted thumbnail.
I also feel that the long delay in VS starting up is at least partly attributable to having a library selected (when VS was last closed down) which contains a thumbnail for a large rendered file.

All I need to do now is to remember what I mentioned above.

1 / Library clips
Yep you will forget that the new rendered file has a clip placed in the library, but its useful to be able to play that new video, we can easily move the clip from one library folder to another, simply drag the clip over the new folder listed on the left. You could create a new library folder called rendered files.
A right click for Locate on Computer is an easy way to locate on hard drive allowing us to play with our media players.

2 / Video Studio editing speed
I find working with MTS type video is much slower than other formats, Initial loading of clips to the library or timelines are much slower to complete
MP4 types seem easier for VS to manage, given like for like types 1920 x 1080.

3 / Video Studio Launch Speeds
You mention that times vary and some launches are faster whilst others take a while, or is it always slow, on every launch?
As the library content has not changed It seems difficult for me to blame the library.
You have checked the library content for clips requiring re-linking and all is well.

4/ Can you tell us how large your library is, how many folders.
Are all files used in the library on your hard drives or are any on an external drive?

5 / You could try resetting the library
First you should Export the Library, this will save a copy
How - Settings Library Manager Reset Library, browse for a save location.
This will save the library as a copy.

With that saved you can Reset the program by renaming the 20.0 folder to (20.0_old) Do not delete this folder
C:\Users\UserName\AppData\Roaming\Ulead Systems\Corel VideoStudio Pro (x64)\20.0

Starting X10 will start with a fresh / empty library
Try restarting the program, do you still have issues with launch times.

Import the library
Settings Library Manager – Import library – browse for the folder / files created in 4 above
Your library should return with original content
