Scene Detection

I have a number of avi files that I have copied to hard drives from various camcorders. I find that PD14 doesn't do a good job of detecting scenes even when using timecodes. Is there any way to combine scenes in the library? Windows 10 64 bit on Puget Systems i7-4790K. 32 GB memory. Hard drives everywhere.

Not sure what you mean by 'combine scenes in the library' but.... have you right clicked on a clip in the timeline and tried Content Aware Editing?

Does this address your issue?

There is a "Combine" option for clips on the timeline. What I want to do is combine scenes in the library area. I really wish it did a better job of detecting scenes. Windows 10 64 bit on Puget Systems i7-4790K. 32 GB memory. Hard drives everywhere.

You can import them again to your hard drive without scene detection. That is how I do it.

I don't think you understand what I am trying to do. I imported video from several sources into another program and saved it all into an avi file for storage purposes. When I import the avi file into PD14, I want to break into the original scenes, as identified by timecode, in order to edit.

PD14 breaks the avi file into a lot more scenes than I originally imported. i.e. I have 1 camera run that PD14 has divided into 5 scenes. I want to combine them back into the original camera run in the library. It's a pain because PD14 is so inaccurate in detecting the scenes, but I don't want to have to put all the scenes into the timeline before combining.

I don’t have any of that experience of saving all my dv-avi files into a single avi file for storage. I believe that the original time codes won’t be written when you combine and resave them like that. My only experience is to capture the original dv-avi with software and a firewire card and use those files unmolested. Those do contain the time codes.

Page 67 of the PD14 user manual show you how to combine, or merge two or more screnes into one longer one in the library. Read the last 3 bullets. What you probably have is scene detect by change in scene brightness/contrast and not time code because there are not any.

Let us know if this help with your scene detection.

I think it best to do scene detection at it's lowest setting, and I am almost certain after detection finishes you can fiddle in that same window with adding/merging/adjusting before heading to the Edit window. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)

I'm almost sure that the timecodes are there because Pinnacle Studio 15 automatically breaks the avi up into the proper scenes when I open the avi, no detection required.

I saw that page, but once again, it is not in the Library Panel. I would have to play the whole avi in order to know which scenes PD14 did not detect. BTW, it does detect a lot of scenes when set on timecode, it just doesn't do it properly. I guess I'll have to continue to use Studio on these files. I was hoping for something better. And Yes, I am detecting by timecode. Windows 10 64 bit on Puget Systems i7-4790K. 32 GB memory. Hard drives everywhere.

I am well familiar with Pinnacle Studio 15. The DV-AVI capture is type 2 while the capture is type 1 for PD14. They are not compatible and must be converted if used on the other editing software. The produced mpeg-2 files however can be used in either with smart rendering. You have this versatility.

BTW: That is not true on my PS15. In the Capture Tab. I have a choice of No Scenes detection, Detect Scenes by Timecode, or Detect Scenes by lighting/contast changes before capturing.

Good luck with your editing.

There is no capturing going on at this point. I open and avi from my hard drive and it opens in scenes. I originally captured as Scenes by Timecode, then outputted an avi. Do I understand that I can open an avi in Studio15, drag all the scenes to the timeling, then output as MPEG, then import that to PD14 and it will be in or detectable as scenes?

I tried making an MPEG-2 file out of an avi in Pinnacle Studio 15 and importing into PD14. Still no joy, but closer. Detected 17 out of 21 scenes. Still a pain to find the other 4 scenes, scrubbing in that small Scene Window. I wouldn't want to do it on a long avi. Windows 10 64 bit on Puget Systems i7-4790K. 32 GB memory.
