Quote: Hi

I am having a strange problem. I had edited a clip in the past and all had worked fine, today i went to open my saved edit file and all looked normal except one clip in the timeline was not playing, it almost looked like the video file had been removed from it's location and it was playing a empty container. The time was running but no picture was moving on the clip, every other clip on the timeline was normal.

I then went to the location of the clip and opened it up to see if everything was ok, and all seemed fine. I then deleted the clip from the timeline and re-added it. Now it adds the clip but for some reason it only adds 32 seconds of the clip where as the clip is over 6minutes long.

I then closed PD completely and then opened a fresh empty copy. I then added the same clip to the timeline and still it only adds 32 seconds of it, where as before it was reading the full clip fine. I have checked multiple times now if the clip is ok. all media players play it fine.

I had recently updated to the beta version so i thought maybe that was the problem, so i uninstalled PD and reinstalled it to the latest version without the beta and still same problem.

My specs are below

Windows 7 64bit
i7-3930k
8gb ram
GeForce GTX 580
160gb SSD that PD and video file are on

Video: MPEG2 Video 1440x1080 (16:9) 29.97fps 25000kbps [Video - MPEG2, Main Profile, High1440 Level, 1440x1080, 29.970 fps, 25.00 mbit/s (0810,e0,00)]

Any ideas?
Thanks

Hi Karaarslan,
1. Do you use Shadow Edit files option checked in Preferences or activated when you bring HD video into PDR12?
2. Please provide the MediaInfo on the clip - see guide Part J.
3. Please provide a screenshot of your project, Edit Workspace - see guide Part E & F.
4. When you re-opened your project initially, you should have had a pop up message requiring you to Browse for a missing media clip, did you?
5. The black space in the track where the clip was, indicates the file has changed location.

I really don't know what has caused the 32 seconds only to display of the 6 minute clip. It may be the Shadow File (if created) is 32 seconds long because it hasn't completed the full 6 minutes. It may be the parameters of the Mpeg changed after 32 seconds and fail to comply with PDR12 rigid mpeg settings (I doubt this). I'd like more information on the situation. You may need to run the file through a converter program and resolve the matter that way - because the file is seen by PDR12 as being corrupt.

I have disabled shadow files, and have deleted the temporary files manually when i had used the feature in the past.

I didn't get any messages about any files being missing when i had opened my saved project. I now copied the video file to my desktop to make sure it is ok. I then open up PD and drag the media file to the timeline and it still adds it as 32seconds... It gives no warning or nothing about the file being corrupt

If there is any other info you need please let me know. I don't see the point in making a screenshot of the timeline as there is really no info there apart from showing the clip being 32seconds long.

Hi Karaarslan,
You may just have a corrupted clip as this appears to be a "one off, one clip" issue. Run the clip through a free video converter software, output the file to the same resolution/fps and then return and start editing.

Hi Dafydd,

Yea sure i can convert the clip and make it readable but it still sucks that PD can't pick-up on the file being corrupt, if it really is a bad file.

The problem is if i have many projects saved with many edits and now if i go and open those saved projects it will be hard to tell if some clips have become corrupt and such, specially with no sign of PD detecting it.


Thanks for your help anyway!

Hi Karaarslan,
This has only happened once for you and not elsewhere in the PDR12 forum. The fastest solution in this instance, is to run the file through a converter program.
