Why import into PD7 changes mpg file date?

PD7, v1714

Why does a simple import change dates of mpg files? This feature is very annoying as dates of raw footage can be very handy when trying to find past footage and so on.

1) start PD7 and import a jpg file and an mpg file into the library window
2) exit and don't save

The mpg file gets a new date and the jpg file does not. PD6 used to leave both dates unaffected. Why would the mpg date change but not the jpg? Aren't both files supposed to be unchanged and simply indexed in the library window? Attached file shows directory prior to and after import into PD7.

How strange - I hadn't really noticed that happening, but it does exactly that, and could make finding clips harder than need be. More for the developers to look at!! Seeking wisdom - finding fluff - but wise fluff!

Hi Jeff,

I have looked through your post and followed your instructions and I cant duplicate this when a file is only placed in PD.
I have right clicked on the file and selected properties, I placed the file into PD using click and drag. I then closed PD. See image 231 of file properties which have remained the same.

With another video file I brought it into PD's Media Library and placed in the time-line. This file shows as being modified. See Image 232.

In both cases the file created date remains the same in my case and when displayed in the folder.

I'm using 1714 PD7

Sounds like another 2 out of 3 so far have issues, Hall and myself. It is very hard to believe simple things like this and others noted on this forum appear so machine sensitive with PD7.

I will play around some more and see if I can isolate the issue a little better. For me, everytime a pds file is opened all mpg files that I have created and are in the library get a new date when viewed with windows explorer, very strange. Rich video, aspect ratio or something? Might PD7 try to append some knowlege that might not be there in my mpg files? All files were captured with PD6 or PD7. I see it does not happen with the aquarium file in c:/Program Files/...., sooooo.

Hi Jeff,

I used scene recognised on capture mpeg files. What are the video files you used? If by placement they're being scrutinised/changed by PD7 with Rich Video (scenes) then I would think that modification is taking place each time.

Let me know what you find.

As always I'm impressed with your thoroughness.

I think it might be easier for CL programs to have a look at the "open" statement for the file in the code and see what they allow for access and modification of the file.
Just to clarify, my pics show the modified date being changed, not the created date. From Dafydd uploaded pics, I'd have to ask the same question, image 232 shows the modified date of the file being changed. Why? What was modified? Yes, the file access date should be updated, but not the modified date.
What this means is for the second video you brought in that created pic232 then every time you use that clip in a project it gets recorded as modified. Say that is the small intro clip you have perfected that you put on all your how to demos. How frustrating that every time you create a new how to video your intro file modified date is changed. Just poor coding in my mind.
I typically capture my videos with DVD HQ profile and simple time limit duration with a Canon Optura 400. I have noticed that PD6 did not change a single modified date on any of these files. PD7 changes it every time you use the file in PD7. Even if you open a PD7 pds file and then close it, no save. The pds file modified date is unchanged since you did nothing; however, the mpg files used in that pds get a new modified date. I end up with a pds project with a modified date older than the mpg files in the project. Sounds like voodoo.

Sorry for the wind, it's not typical of me.

Jeff

Hi Jeff,
There is a case for this occurring in PD7 with mpeg files. PD7 will do file indexing to speed up file seeking and that data is saved in RichVideo. If you want to you can turn off this facility by making a change in:
Edit > Preferences > General > Rich Video - dialog box.

Thanks Dafydd, but that's not it at least for me. I have both Rich Video settings in the preference dialog box not ticked as I thought that may have been the issue. Even with them not ticked, I still get the modification dates of my mpeg files changing. That's why I suggested maybe a look at the code would be easier.
