Scene Detect on Existing Clips

I have about a dozen 20-30 minute films I have captured to video tape and have loaded into my system. Because of some of the content of the tape, and historical/geneological images, I would like to break the films down to individual scenes and then attach metadata and other info to the scenes for later tracking or sorting. (Through Bridge)
With the films captured, though, it is a bit problematic. Making sub clips, or "converting to master clip" doesn't work (which was expected) but is there any way to use scene detection with the existing AVI file, to break the films down to individual clips? Or, is my best bet to re-capture the films with scene detection set to on and use those individual clips?
Thanks,
Bill

Yep, that's what I thought. I was thinking of scenealyzer as well...

Scene Detect on a clip after it's been captured?

I've got a clip with multiple interviews on it. I'd like to cut it up into the individual interviews (which all have a fixed camera). I know it can do this when you're capturing a tape, but is there a way to have Premiere autodetect where the cuts were and split up the footage automatically for a clip that's already in your project?

FAQ:How do I do scene detection with video files?

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?

Using Auto- Analyzer for Scene detection only (and save time)

As a completely new user of Premier Elements 8 (running on a AMD phenom 3 core, 4g Ram, 500G Sata HD, Win Xp prof) I brought into Organise in the PE8 workspace clips imported in through Windows Movie Maker from my old DV video camera. I wanted to dectect the scene boundaries so I ran Auto-Analyse from the PE8 workspace. This took upto 4 hrs to analyse a 1hr clip which puzzled me as Movie maker only took about 20mins to detect the scenes on a much slower and lower spec laptop.
Tip
If you just want to Scene Detect don'r run Auto-Analyze from Premier workspace instead start with your first clip via the Organiser.   Reason - In the PE8 workspace "Edit" "preferences" Auto-Analyze does not appear so it will run with the defaults which is all tag options selected e.g "focus" "face recognition".
Instead go into Organise from the front page launcher, in "Edit" "preferences" Autoanalyse does appear with all the tag options selected as default   If you deselect all options and then run Autoanalyse on the video clip only scene detection runs on the video (the 1 hour clip was analysed with just the scene boundaries in less than 15mins!) The change from the default seems to apply when you run from the PE8 workspace after this so subsequent scene detection on other clips runs quickly.
P.S.
Old hands may know this trick but so far I had not picked anything up from the web based docs and information - so this is for novices such as myself. There may be other ways of scene detection but in my limited experience have not come across any yet.

Capture with Scene Detect: Clip Name Keeps Changing

I am editing weddings and my raw footage is usually on 3 tapes. I capture with Scene Detect checked and I name the clip "Clip", so Premiere labels each clip as Clip 01, Clip 02, Clip 03, etc. But when I put in my 2nd tape, Premiere starts labelling them Clip 01 1, Clip 02 1, Clip 03 1, etc. How can I get Premiere to continue from the last number of the previous tape, (the same way that Scenalyzer does automatically)?

How can I get Premiere to continue from the last number of the previous tape
You can't. Once you stop capture, PP will always restart the numbering, even if it's from the same tape.
What I do is use Bridge to Batch Rename the clips.

Use of AUTOMATIC SCENE DETECTION on already existing huge file

Hello to all for the first time,
I have 6 HUGE already imported video files of my videos diary from Himalaya, so they are each 1 hour long files now and to edit the story I need to brake each of those HUGE imported files into individual clips!!!
Of course I can make new smaller clips manualy but my TIME SAVING question here is how can I make iMovieHD AUTOMATIC SCENE DETECTION work on already imported huge file? So that I just play the HUGE file and it automatically brakes the individual clips and makes different files/clips.
Got it?
Hope somebody into the know will read this.
Thank you
Vladan
G 4 titanium Mac OS X (10.4.9) love it

Thank you Sue,
Thank you for wellcome, great you want to help.
So I imported all my video (from Hi8 - remember) trough firewire in using iMovieHD ... and that is how I got here where I have those huge documents, each 20 Gigs, on my external drive.
so thats where I am at and I would like to RETROACTIVLY (I quess) use that automatic scene detection and out of one huge file (clip) get say 15 smaller clips.
Is that clearer
thanks again

Speedgrade crashes every time I use split into clips function as part of scene detection.

Speedgrade CC (latest version) crashes every time I use split into clips function as part of scene detection.
I can use the keyframe function fine, but if i split it into clips it crashes 9 out of 10 times... so to get the job done i simply keep reopening the project, cliping and praying it works, then it crashes.... and i repeat this until it doesnt crash!
File format im using is a 22min long Prores422 HQ 1080 25P file.
Any ideas?.... im guessing im going to get the old "reinstall the software" one first... anything else?
also have issues with Speedgrade just crashing for no good reason at random times while im grading too but ive come to expect that from the buggy software.

I've got several 1080p mov's that have multiple sequences with 20 to 40 minutes a sequence I've regularly run over to Sg from PrPro. Granted, they're pretty straight forward, mostly simple cuts with a few transitions/wipes, no more than 3 video layers a sequence. Only one has any Ae stuff on it, and again, pretty simple.
But as noted, there are those who do programs for broadcast with it ... I'm wishing one would chime in. Maybe shooternz ... I think he does b-cast work. Vastly more experienced than I am, PrPro, Ae, Sg, Audition ... the "suite". There's several others around here, though they tend to 'hang' in the PrPro forum more than here.

Speedgrade scene detection clips export easily into premiere pro??

I have a .mp4 movie and want to scene detect it to get different clips using speedgrade.
Then I want to switch to premiere pro in the most easy way!
I dont want to change the order of clips. the clip splitting is just for speedgrade adjustments.
(Im just starting to use the programms)

SG erzeugt keine Clips. Die Szenenerkennung wird nur intern verwendet, um separate Korrekturen voneinander zu trennen. Wenn, dann müßte jedes Segment separat exportiert werden. Aber umgekehrt kann SG wunderbar vorseparierte Premiere Sequenzen verwenden...

Scene Detection On Previously Captured Clip?

Is it possible to split an already captured clip into scenes (much how scene detection works during capture) on a sequence timeline?

For DV, check out DVdate; you can split a DV file both by time-of-day timecode and optically. It will bust the scenes out into individual AVI files--I'm assuming you're using a Windows machine, here.
For HDV, check out HDVSplit. I haven't split an HDV stream after-the-fact, but that capability is supposedly available in HDVSplit.
Both programs are free.

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

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

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).

Automatic Scene detection

Hi,
I just purchased a Powerbook and I am a new Apple user (converted from PC). I used to use a Pinnacle program but now I am very excited to try the iMovieHD which comes with the laptop.
Unfortunately, when I tried to create my first movie, I have a problem already with importing my images. My images won't split into clips. The program only shows everything as 1 long clip. I checked my preferences to make sure that the automatic scene detection feature is on. I didn't set the time and date of my camcorder.
My question is: (1) Is setting the date and time of my camcorder really criticial when you import the images? (2) eventhough the date and time is not set, i have several scenes which were shots at different time, but iMovie still didn't pick it up as a new clip, eventhough there was a good 5 seconds of nothing in the tape. How can that be? (3) if setting date and time the only way to do an automatic scene detection, what will be my next option to create several clips. Is there a way to do it manually (please...I hope this is not the answer).
Any tips are greatly appreciated. I already convinced my husband to convert from PC to MAC, hoping that for media stuff MAC is better and friendlier than PC. Please, show me that this is true.
Thanks in advance,
Amanda

Here is a link to an Apple Article about automatic scene detection:
http://docs.info.apple.com/article.html?artnum=61412
My clock was not set, but as soon as I turn the "internal clock" on, it shows the correct time and date right away.
I'm a bit confused now! If the clock is showing the correct date and time then it must be set and shouldn't be causing a problem with scene detection. With my camera (see details below), when I switch to record (standby) mode and select the menu item Clock Set, it shows the date and time, but there is no switch to turn the clock off or on.
It might be worth doing a short test recording with, say, 3 or 4 short scenes with a break of about 10 seconds or so between each scene. Import that to iMovie and see if the scenes are automatically detected (make sure the preference is checked first). If not, it might be worth deleting (trashing) iMovie's preference file - it's in your User (Home) folder under Library/Preferences and named com.apple.iMovie.plist. A new default preference file will be created by iMovie next time it is opened - you may then need to change some settings to your own preference, as required. Note that preference files in OS X can sometimes become corrupted - trashing them can often fix minor issues.

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 on Capture?

Primere Pro has an option when capturing "scene detection", makes capturing individual clips easy and fast. I would think there's a similar feature in FCP 5.1?

Start/Stop detect does not, on its own, make individual clips. You use it in a process to make 'sub-clips'. Sub-clips are pointers to the main clip, they are not individually editable files.
If you are shooting HDV, FCP5 can create new clips on GOP frame breaks which is the same thing as scene detection.
If you are shooting DV, you need a 3rd party app (for example CatDV + Live Capture Plus) to create individual clips from long captures.
good luck.
