Detecting changes in video

Greetings all. I'm new to video editing and Premiere.
Is anyone aware of a plug-in or software that can detect changes in video? I have been setting up my camera to shoot lightning vids, then walking away for minutes at a time. Needless to say, the flashes can be as short as a couple of frames, and locating these extremely short sections of clips can be very time consuming when visually searching frame-by-frame.
I would think there would be a need for something like this for not only my situation, but for nature video or surveillance. The ideal app would locate changes in the scene and mark or log the locations.
Thanks for any advice.
Jeff Barnett

Ok, wise guy! Are you telling me that you wouldn't chase lightning with me just because I've been hit before? Basic math: The odds are the same for me being struck now as they were the first time when I was 9. It's not like I go out wrapped in tin foil and climb trees to catch the perfect shot!
And I'm sorry, but I ain't 18 no more ... I'm 55. I finally realized that I'm not indestructible like I was at that age. Besides, call me a weenie, but lightning images with interesting content (cityscape and North GA mountains in the distance), shot from within a giant Faraday cage (office building), is more visually interesting than from under the eaves of an aluminum strip shopping center with a tree shrouded 7-11 in the foreground! We have lots of trees here! LOL Like I said ... never found the great shot!
Actually, my Canon does have a pre-roll function, but only 3 seconds, if I recall correctly. Really cool feature that I've used in conjunction with my remote to record a wren repeatedly returning to feed her hatchlings in a barn.
I've used slaves for still work, but I'm not sure if I can get one to trigger my camcorder. I would either have to have some kind of PC (flash trigger) to infrared remote converter, or one that converts to the LANC input. Maybe other options, but I haven't discovered them.
Thanks for the info, chuckle, and vote of confidence!

  • Is it possible to change the video card of a pavilion g7-1075dx?

    So, I have an HP Pavilion g7-1075dx Notebook with Windows 7. I'm an avid gamer and wish to play the newest games. However, there's one problem thats keeping me from doing so. Alot of the newer games require newer video/graphics cards. This particular laptop has an ATI Mobility Radeon HD 4250. The newest games seem to require ATI Radeon HD 4850 and above. This is the only thing thats keeping me from playing games like Starcraft II on the highest settings OR in the case of Star Wars: The Old Republic, it almost keeps me from playing the game, period, due to the graphics being too much for my current card to handle, causing massive lag. I was hoping I could change the video card. Upgrade. However, i've heard that with most laptops or notebooks you can't upgrade anything other than the RAM. I'm hoping anyone on here can help me out and tell me if it is possible to get a new video card for my laptop. We don't have a desktop computer so this laptop is my only hope for a long time to play newer PC games.

    Alright, let me put this in a simpler message: Does anyone know if it is possible to change the video card currently in my laptop, the HP Pavilion g7-1075dx, for a newer and better one. ATI Mobility Radeon HD 4250 to ATI Radeon HD 4850 or higher.

  • Using a function to change Netstream video size.

    Hi folks,
    forgive me I am new to script in Flex.  I got an Application that has two scripted functions.  The first is called at creationComplete and sets up a netconnect/netstream video playback.  And a second that is fired when a button is clicked, which sets the application to Full Screen.  What I want to do is resize the video at the same time.  For testing purpose I am using hard coded values that match my monitor size.
    The problem I am having is that the code I wrote to change the video size spits out an error "1120: Access of undefined property vid."  - Is it possible to have one function access the vairibles of another function?
    My code:
    <mx:Script>
            <![CDATA[

                    var nc:NetConnection = new NetConnection();

    Hello,
    I have an XY-Graph with 4 plots. How can I detect, for example, the color change of the second plot in the legend. The active plot, using a property node, is always plot 0. So I am not able to detect changes in the 2nd/3rd ... plot.
    Any ideas?
    Thanks a lot.

  • Change of Video Frame One Sample Out of Sync with Correct Point on Timeline

    Change of Video Frame One Sample Out of Sync with Correct Point on Timeline.
    It has been found on the author's PC that, in Audition 3 in Multitrack View, a video file displayed in the video window will change its frame one sample later than it should do with respect to the correct point on the timeline. This has led to extra work having to be done by the author, as detailed later.
    To demonstrate this issue:
    Create a new multitrack session. Enable the Time and Video windows. Enable only 'Snap to Frames'.
    Using an external program, render a two-frame video clip at 25fps. Let the first frame contain the letter 'A', and the second frame contain the letter 'B'. Making sure that the Display Time Format is set appropriately, in this case at 'SMPTE 25 fps (EBU)', lock this clip on the multitrack timeline, ensuring that the clip starts at time 00:00:00:00.
    Create a mono audio clip of silence at 48kHz 32-bit that is two frames long. Lock it on an audio track, ensuring that the clip starts at time 00:00:00:00.
    Place the cursor at time 00:00:00:01 and create a cue marker at this point by pressing F8.
    Zoom into the timeline so that approximately twenty samples are visible, with the cursor lying on the cue marker in the middle of the screen. The Time window should display 00:00:00:01. The Video window should display the letter 'A'.
    Move the cursor back in time (leftwards) by one sample. The Time window should change its display to 00:00:00:00, whilst the Video window should still show the letter 'A'.
    Move the cursor forwards in time (rightwards) by one sample, so that it overlays the cue marker again. The Time window should change its display back to 00:00:00:01, whilst the Video window remains showing the letter 'A'.
    Move the cursor forwards in time (rightwards) by one more sample. The Time window's display should remain at 00:00:00:01, but the Video window should now display the letter 'B'.
    As can be seen from the above steps, the video's change of frame content occurs incorrectly one sample later than it should; the change of video frame content should occur simultaneously with the change of the frame number displayed in the Time window, which is at the point that the cue marker has been placed.
    The practical effect of this issue is that it has caused the author a huge amount of extra work on an 89-minute long soundtrack-for-video timeline. There were over 1100 changes of shot which the author wished to mark by placing cue markers at the beginning of every shot. This should have been a quite simple process of enabling 'Snap to Frames', stepping through the video, and laying cue markers down by pressing F8 when the shot was seen to change.
    Because currently the Video window (referencing the cursor laying over a cue marker
    i that has been placed on the timeline using the 'Snap to Frames' option
    ) will actually display the end moments of the previous frame rather than the beginning moments of the current frame, laying down a cue marker when the shot is seen to change will actually place that marker at the beginning moments of the second frame of the new shot, not at the beginning moments of the first frame of the new shot, i.e. the cue marker placed will be one frame later in time than it should be. If it is wished for the cue marker to, as best it can, represent the beginning moments of the first frame of the new shot, it has to be manually repositioned so that it is at least a sample later in time than the time at which the shot has actually changed, in order for the Video window to correctly display the content.
    The author had to manually reposition all 1100+ cue markers.
    Ideally, the Video window should display a change of video frame in synchronization with the change of the frame display in the Time window, which occurs at the position of the 'Snap to Frames' point.

    P.S. Can you please tell how this forum can be identified code \ listing?

    Hello,
    I don't know if there is a way to change the video. But I think you can easily use your own videos by using a local .mpg or .3gp file via InputStream. Just change the player's parameters in video/mpg instead of capture://video.
    Hope it helps...

  • I mistakenly changed the video type to iTunes U

    I was intending to classify it as a TV Show. Now I cannot see it on my Itunes U library therefore I cannot change the video type to the originally intended TV Show. I know the file exists by using Finder and browsing all the way down to Itunes U folder, but I can't edit the information (actually the "get Info" box in Finder is completely different from the "get Info" box in Itunes).
    How can I make this files show up in Itunes U so that I can change the video type once again? Is there a way I can change the video type form outside Itunes?

    Does it show up if you create a smart playlist with the rule Name is <Name>, or a similar constuction using the details you can recall? If so then you will be able to reset the Media Kind.

  • Event Structure's value change, not detecting changes when tabbing thru array of clusters

    Hi!  I have an array of clusters (int, int, string, int) control, and want to detecting changes made to the it.  I used the Event Structure's value change case on the array, it works excellent except that it'll only detect the changes when you click out of the element or press the enter key (the one by the numbers, not carriage return).  I want it to detect the changes when I tab thru the cluster or array too, but I can't figure it out... Does anyone have any ideas?
    Thanks!

  • ITunes U can not change the video view size to 1x

    After updating to iOS 6, I realised that the iTunes U video play can only display the maximal size view which makes the video quality very poor and there isn't any way for to change the video to 1x size. I wonder if anyone has found a solution for this issue yet. Thank you and look forward to hearing answers about this issue.

  • Help! How to change the video frame size during RTP transmission

    Hi there.
    In a RTP transmission:
    How can I change the size of the frames of the video while I have the processor in the server running?
    i.e. while the server is running, i want to change a video from 400x200 to 200x100
    Thanks

    I am trying to implement the same functionality. I've tried to reset the format using the trackControl.setFormat method but this only appears to be supported while the processor is in a configured state. I'm still investigating, but if you happen to know a solution please let me know.
    Here is what I'm trying to do... In the middle of a session, I'm trying to change the video format from h263/rtp:352x288 to h263/rtp:176x144

  • Detect changes in an instance

    Hello,
    how can I detect changes in an instantiated object? I could serialize the object and write it into a file. After some minutes I could write it a second time into a file. Now I could compare the two files. But I thing this is not the best way for doing this, isnt't it.
    Any suggestions?
    Thanks

    it can be of any help, here's how I implement object changes:
    /** Interface for object instances comparison */
    interface ContentComparable {
       /** Returns a string describing the object instance for comparison */
       public String getCompareString();
    /** Custom class sample */
    public class CustomClass implements ContentComparable {
       private String    customField1;
       private int       customField2;
       /** Constructor */
       private CustomClass(String field1, int field2) {
          this.customField1 = field1;
          this.customField2 = field2;
       //------------------------------------------------------------ ContentComparable ---
       /** Returns a string describing the object instance for comparison */
       public String getCompareString() {
          String content = this.getClass().getName() + "["
                           + "customField1='" + this.customField1 + "', "
                           + "customField2=" + this.customField2 + "]";
           return content;          
       /** Returns TRUE if the object is equal to an other object
        * @param   otherobj  the other object
        * @return  TRUE or FALSE
        * @see #getCompareString()
       public boolean equals(Object otherobj) {
          if (otherobj instanceof CustomClass) {
             CustomClass classobj = (CustomClass)otherobj;
             return this.getCompareString().equals(classobj.getCompareString());
          return false;
    }With that, you just have to keep a copy of the getCompareString() of the object before any changes are made.
    When you want to test changes, call this method:
       // private member to hold copy of unchanged object string
       private String oldObjectValue;
       // Returns TRUE if object has changed
       private boolean testDataChanged() {
          if (oldObjectValue == null) oldObjectValue = object.getCompareString();
          String newObjectValue = object.getCompareString();
          return !oldObjectValue.equals(newObjectValue);  
       //...Hope this helped,
    Regards.

    I'm not sure of your question.

    It edits in 720P HD, which is 1280x720.
    You can make it a bit bigger so you can zoom in.

  • How do you change multiple 'Video Kind' values at once?

    Hello,
    first of all, sorry if this has already been asked, but I tried searching for a straight answer in here and in other forums without any luck..
    .. but I was wondering if there is a way to select multiple videos, and change their video kind to something else, all at once(eg. from Movie to Music Video)...
    ...When I select a group of videos and click get info, it doesn't give me the option to change the video kind, so I've had to change each one, one at a time, (which gets very tiresome :P)...
    ...so is there a way to change multiple 'Video Kind' values at once, or should I pray that it becomes available in the next update of iTunes?
    Pentium 4 3.0 ghz Windows XP

    You can't do it right now. Wait for the next update, and hope it's there.
    For the moment, I suggest selecting Get Info on one song, changing the setting, then hitting the next button at the bottom to go right to the Get Info for the next song. You can rapidly change lots of these that way.

  • Changing multiple video tags in iTunes7

    I feel fortunate to say that I've had no problems at all with iTunes 7, which seems to be a fabulous upgrade. I've upgraded all three of my Macs with no problem.
    I'm wondering, tho: All of the video I've ripped from concert CDs then converted for iPod thru Quicktime Pro shows up as "movies" in the new video tags pane. However, changing them one-by-one to "music video" is going to be tough, with 700 of these files ready for conversion. But when I select multiple files, it does not let me go to the VIDEO tab option (it only shows up in the single-file info box). Anyone know a way around this? Thanks in advance...

    This shortcoming of iTunes has bothered many of us for a long time. All the TV shows I offload to DVD-R for space and then later bring back into iTunes become "Movie" again, and I have to fix each one. There is no way to batch-edit the Video Kind choice in iTunes.
    The easiest workaround I've found is to select the first TV show in the playlist or library, Get Info, change the video kind to "TV Show," and then use the Next button. The Video Kind box will remain active, and you can press arrow-down on the keyboard to choose "TV Show" again. Click Next, arrow-down, click Next, arrow-down . . . Soon you will have fixed all the files in the list.
    Now start at the top again and type "South Park" into the Show field. Copy the words. Click Next, and paste the words. Next, paste, Next, paste . . . Now you will have given all the shows the correct name.
    Another oddness about this Video tab: See the box for episode number? ITunes doesn't use that in the TV Shows library. It uses the music track number on the General tab.
