Scene Detection off by two frames

I'm using CS5.5 on a Mac. I'm capturing DV footage from a digital 8 tape. I captured the whole tape and selected scene detection. I noticed that the last two frames of each clip were actually suppose to be the first two frames of the next clip. So in other words what should be the first two frames of clip 2 end up being the last two frames of clip 1 and clip 2 starts on frame 3. Is this normal? Is this just a programing flaw?

PE10 for Mac: Scene Detection off by two frames

First I didn't relized it, but all my captured DV scences have 2 frames at the end, which belong to the following scence.
I used a Canon MV-200 and a Panasonic NV-280 (both MiniDV cameras) for capturing and scence detection by timecode.
I think I can exclude them for being responsible - they work excelent with iMovies (Mac) and Pinnacle (Win).
Then I found the Device Control Preferences and thought that's it!
But unfortunately, the timecode offset (positive or negative) has no effect on the sence detection.
Hmmm, now I running out of ideas and the resources about these settings are very rare.

Scene Detect 8 + 15 extra frames on every captured clip

When capturing HDV in CS5, using Scene Detect creates extra frames.
Imagine clip #1 when it captures its footage, instead of stopping at the end of the clip, it continues for another 15 frames into Clip #2 and tacks this on to the end of Clip #1.
It then starts to capture Clip #2 but first it rolls back (this is done by Scene Detect electronically. The tape does not actually roll back) into Clip #1 and starts the capture 8 frames back into Clip #1 before it continues capturing the footage and proceeds to repeat the 15 extra frames capture from Clip #3. Everything is repeated throught Clip #3, Clip #4, etc. until the end of the tape.
These things did not happen in CS3. This is a CS5 problem.
Essentially each clip starts with 8 frames of the previous clip and ends with 15 frames of the next clip. The extra frames contain both video and audio in perfect sync.
When capturing, I am making no adjustments on the frames control which is what the Adobe Service suspected. I ran a capture with them on line demonstrating the problem.
Although I can still edit with this footage, using scene detect, with 280 clips per hour tape, it is not pleasant removing 8 frames from the front and 15 frames from the back of each of the 280 clips.
Is there a solution to this problem or perhaps a quick-automatic way of removing the frames from each of the 280 clips?

Exporting cuts off last two frames of project

For the last while now, Premiere CS6 and Media Encoder continue to cut off the last two frames of any project I export. It doesn't matter what export formats I choose, it always happens. My short term solution has been to extend the project by two frames but sometimes that doesn't even work. Anyone else have this issue? It's really becoming a bother. And yes, I've checked to make sure the entire project is selected in the export and media encoder windows.
Thanks

Thanks for the follow up information.
Before we advance on the cropping details and considerations, let us rule in or out the set up of the project as well as the export choices and settings as causes of the problems.
If you have video 1440 x 1080 HD anamorphic 16:9, then the project preset should be (assuming NTSC setup)
NTSC
AVCHD
HD1080i30
Now, when you go to export your edited Timeline content, if we go for a H.264.mov export
Share/Computer/QuickTime with Presets = NTSC DV 16:9
Click on the Advanced Button there.
Under the Advanced Button/Video Tab, set according to the screenshot for Video Tab....
Some of the export settings in the screenshot got cut off in the screen capture. The essential ones are the ones you see (for now).
The BItrate which is further down (not seen here) is left with no check mark before "Limit Data Rate To...". We will work on that later if file size becoms an issue. The main purpose of the above is to see if we can get a good video just with attention to project setup and export settings.
We will be watching for your results.
If any questions or need clarification on any of this, please do not hesitate to ask.
Thanks.

IMovie and auto scene detection

i would really really like to turn this option off.
in previous versions iMovie imported full clips - how do I get it to do this again with iMovie 9??
I looked in preferences and do not see the option to turn auto scene detection off.
I use iMovie to import and then i turn around and export to QuickTime Full Res for use in Final Cut Pro.
Thanks!
Enero

iMovie does not capture timecode...which is one of the most important things in video editing. If you edit and spend months on a project, and the drive containing your media dies...gone...then you are hosed. Because you cannot recapture the footage exactly the same way you did before...you'll have to re-edit from scratch.
If you have timecode, then when you went to recapture the footage, it would keep the same IN and OUT points and recapture the clips and your timeline would remain intact.
A better way? What is wrong with capturing with FCP? It is designed to do this you know...
A better way would be to get a capture card like the AJA Kona LHe and capture the footage as DVCPRO HD. MUCH easier to work with than HDV native, and not as lossy picture wise as AIC.
Yes...the AIC has significant quality loss. But..depends what you are editing.

I am having problems copying and pasting clips from one project timeline to another. When I do this they often alter in length. Sometimes by two frames. Other times they lose a chunk off the end of the last clip in the sequence. Has anyone else found

You need to give a lot more information about the media specifications and the project properties you're using in the different projects.

Turn off scene detection?

Three years ago I edited a project on FCP, then recorded it back to mini DV tape.
Now, when I try to import that tape, imovie rearranges all the shot, cuts out the transitions,
and makes each one a separate shot. It imports everything, but cuts it up and rearranges everything.
Is there some way to turn off the scene detection? I've tried using the manual import, but that does no better.

No, sorry, there is no way to turn this off. This is the default behaviour of iMovie 09. It does not play well with older, edited projects from the Apple software offerings. The transitions will not work in the new iMovie.
You can try iMovie 6 HD and see if that works. Or start from scratch.

IMovie Scene detection when capturing and hot keys

Two questions please (this is on a new imac) :
1) I have scene detection turned on for capturing (using a XL2), but it doesn't seem to stop and split up the scenes.
Does the scene detection only work when the time-code is broken - ie;
when the machine is powered off and on? Does it detect when it is paused?
2) Is there a list of hot keys for editing like the RAZOR tool etc?
Thanks in advance,

Scene detection normally works, so there must be something going on with you old camera.
I have a bunch of old analog 8MM tapes that I imported through a DV 8MM Digital camera. These all came in as 1 long clip.
It is true you can delete a frame and then use iMovie to split the events. However, I have found a much quicker way that is non-destructive and allows you to enter the date metadata.
1) Download and install MPEG Streamclip from Squared 5. You can google it.
2) Drag your long clip into MPEG Streamclip. (If you don't know where it is, Right-click on the clip in the imovie event and select "Reveal in FInder".
3) Think if dividing your long clip into Events (everything you shot on a single day, for example) - and Scenes (clips) - an individual unit of footage within the Event.
4) Move the MPEG Streamclip playhead to the beginning of the 1st scene and press I for in point. Movie the Playhead to the last frame of the scene and press O for out point.
5) Now, FILE/EXPORT TO DV. Save it to a location you can easily find, like a folder on your desktop. Give it name in the following format: clip-yyyy-mm-dd hh;mm;ss.dv This will preserve the time metadata for later when you are editing. You may want to have your camera handy so you can easily see this data.
6) Repeat this process until you have all clips done. You should find that the playhead is still at the out point. You can simply type I and you have set the in point for a totally nondestructive capture of the next clip.
7) Finally, open iMovie and use FILE/IMPORT/MOVIES... and navigate to the place where you saved all these clips. iMovie will import and sort into Events (you may have to check "split days into new events". Let it generate thumbnails and you are done.

Scene Detection Broken in CS6?

I'm having awful difficulty capturing video in CS6. Specifically, every 60 seconds or so CS6 keeps prompting me to save the scene it thinks it's captured, even though scene detection is *not* checked (it is off) and abort on dropped frames is also off.
I'd be happy to just have it capture the tape as a single scene, but it refuses to cooperate.
I am unable to disable scene detect, it seems.
The only other reports I was able to find relate to CS5 and the suggestions there do not seem to make any difference.
Re: Possible Work Around for Capture and Scene Detect
Anyone else seen this problem?
Setup:
Mac OS X 10.10.2
Canon GL2 (mini DV; firewire)
Premiere Pro CS6

I ended up enabling scene detect and babysitting this particular tape. That was extremely painful and not what I expected from a professional product like Premiere.
As a side note, it seems like scene detect works and that this is perhaps a problem with a separate mechanism that tries to detect the end of tape or something.

Scene Detection Question

I have used scene detection successfully several times but I have one clip where scene detection has identified 40 scenes correctly but when I split to clips many of the identified scenes do not split. The clip is 2825 frames long and it splits the last four detected scenes but not the first 36 detected scenes.
To get it to work correctly do I need to change the sensitivity and rescan?
Any help or insight is appreciated.
Dave

I discovered the solution; so for anyone else with this problem. It was apparently an issue where the scene detector identified two frames side by side in a couple of spots. I changed the sensitivity to exclude those frames which were actually part of a longer scene. Then I split to clips and all is well!
I guess I should have experimented more before posting.
Dave

SG Scene Detect is a NOP -- how do the sensitivity controls work?

I have a four minute clip that produces a complete flatline in SG Scene Detect.
My guess is that it may have something to do with the content: it is 8mm film partially digitized to HD (i.e. SG/SD is part of the process) so is letterboxed on L/R... I'm thinking maybe all that black is driving the detector crazy.
In any case, NONE of the documentation I can find gives any hint at all as to what the "sensitivity" controls do. Is there a document anywhere on this?
What I see for controls:
- Large arrow (and digits) that can be moved with mouse or shift-mouse (for speed). Default value 2.0
- If the value is changed, a blank box shows up on lower right. It appears to reset the value.
- A small square below the line appears to signify nothing, at least for now
- Tooltip says "Press ctrl to toggle Gang" -- so there's a set of ganged controls somehow
- The normal slider range is 1.25 to 4.0
- If I go beyond those values high or low (even negative), two extra markers show below the line, and approach from both ends simultaneously toward the small box
- Sliding left increases the number without limit (I dragged up to 35 billion). The two lines appear to touch the box at around +130
- Sliding right decreases the number below zero also without limit. The two lines appear to touch the box at around -130
Pressing 'ctrl' may toggle a Gang but I guess I'm not a Gang Member -- I can't see where the Gang is hiding out
In any case. I'd love to know what these controls do. And I'd love to actually detect a scene in my clip!
Thoughts?

Yes it is possible to secure the network so that only your family members should access the internet ......
Open router set up page using http://192.168.1.1 ....you will see username & password screen .... leave username blank & in password use admin.....
Click wireless ...change the network name to any non-linksys network name .... click save settings....
Click on wireless security ..... use either WEP or WPA security level...... have a note of the key ..... click save settings ...
On wireless computers once the wireless utilitied are configured to all computer .....only the configured computer will go online

Scene Detection in Final Cut Pro

It would be really awesome if Apple could develop some sort of scene detection software for Final Cut Pro and Color. A lot of color correction work that we do in the DaVinci comes from edited programs off of tape. It would be nice to speed up the notching process to open up Color to people not using Final Cut Pro.

yes that would be lovely, but it would require realtime playback to make it worthwhile. No, COLOR isn't a daVinci in that department. And besides, daVinci never detected dissolves or other subtle scene changes --and could generate spurious event boundaries with fast-moving objects or wildly varying contrast.
I agree that it would be great especially since correcting a "baked" show is really a serious compromise to begin with. In this scenario, you're always going to be faced with keyframing transitions, the colour non-linearities associated with that, and likely a drop/non-drop issue if you use "Import as Cut List". See the release notes. Otherwise, hand-cut french fries-- and ALWAYS a better idea to do that in FCP before sending to COLOR. Trust me.
Nope, bringing in the layered sequence from FCP, even if it has been translated via AutoDuck from some other edit package, is the method of choice.

Premiere Pro CS4: Timecode issues (Scene Detect, Free Run)

Hi folks,
I am most familiar with Premiere Pro CS3. In the past, I have created multi-camera sequences that are synchronised by timecode. I have been shooting using the Free Run timecode feature across all cameras, as to maintain a sync'd timecode.
Now that I am using Premiere Pro CS4 at work, I am running into a few issues in preserving my timecode values during capture. I have recorded HDV footage using two Sony Z7's. I downconvert the HDV footage into DV upon capturing - this is so that I can use the scene-detect feature, and still supposedly preserve the timecode for each media file. I captured all of the tapes using scene-detect, and the timecode values were correct for each media file captured.
Having saved, closed, and reopened my Premiere Project the next day, the timecode values for the majority of the media files have been reset (ie, they all start at "0:00:00:00". This is very odd! Only a few of the media files have retained their correct timecode values.
Has anyone else experienced this? Could they please shed some light on this problem or quirk? Am I taking the wrong approach in capturing/organising media? I am following the same procedure as I had done in PPro CS3.
I have since deleted the Media Cache/Preview Files, requiring Premiere to re-index, and re-conform the media files. The timecode values are still incorrect. When I select all of my media files and tell them to go 'offline', the correct timecode values re-appear.
Many thanks for your help,
Andrew

Does anyone have an answer to this problem?? I think I am having the same problem. I don't have as much experience as the others on the
forum, but basically what I tried to do was filming a multi-camera event in free run timecode, then
captured in HDV split, and assumed I could get Premiere to align the clips accordingly. Anyone have any idea how to do this????
Any help is appreciated,
Thanks,
Aaron

My scene detect in Premiere cs3 on WIN 7, 64 bit is ghosted and can't turn on

I have my premiere cs3 on two computers one with xp pro and the other with win 7 64bit and I can't activate my scene detect on either operating system, I read manual and did some on line searches but it assumes in the tutorials it is already active. Am I doing something stupid or is there a way to turn it on
Joan

Yeah, sorry I should have been more specific. There is no way in Premiere to split it, which still amazes me. HDV split works great though. I just noticed the name of the OP, you would think that they would know that....

Automatic scene detection: Pros and cons

I am new to Premiere Pro. I have used Pinnacle Studio, where scene detection involves the storing of the scene information in a separate file from the captured video, which is stored in a single AVI file. I run Premiere on Windows, so as I understand it, the options I have are to capture my video to a single file, or to use scene detection, which creates one file per detected scene.
On the one hand, having a single file per DV tape is convenient. On the other hand, such a file is rather large.
On the one hand, using the scene detection feature will result in a large number of files. On the other hand, any files for scenes that will never be used can be deleted, saving disk space.
What I'm looking for is how others prefer to capture video -- either in one file or in multiple scene files -- and why you prefer to do it that way.

Scene detect.
I discovered the hard way long ago that each of my camera ops needs to set date/time on their camcorder or else it doesn't work (why they never set it, who knows...).
Add to that, if the little battery dies in the camcorder, it'll toss out the date and all saved functions - including white balance - each time the camera is turned off. Little things you learn....but anyway....
Yeah, scene detect, for all the previously mentioned reasons. I do multiple attempts at some shots, even in event work. By having individual files, I can toss the unused clips once I'm done selecting my shots (or at least set them as offline).
