Video Tracking in Flash

Does anyone know how to do video tracking in flash? I want a
camera to record movements and transfer them in real time as
commands to an object in Flash. Is this even possible?

Doable. Yes.
Easy. No.

  • Does Flash Access support encrypting the specific audio/video track in a multirate video file?

    Hi,
    It seams that Flash Access supports encrypting the multirated mp4 file. By setting encrypt.contents.video=true, encrypt.contents.audio=true, the encryption process will encrypt all the video tracks and audio tracks inside this mp4 file.
    I am wondering:
    Does Flash Access support encrypting the specific audio track or video track by giving the trackID for a specific bitrate inside this multirated mp4 file?
    Thanks in advance,
    Xia Hui

    I am not aware of existing or new feature which allows to encrypt particular track. You can encrypt all audio, all video or both.

  • Monitors for each video track?

    Is there a way to have seperate Monitor windows for each video track, so as I scrub through a Sequence I can have a preview of what is on each  track all at the same time (without using the Multi Camera editor)

    What I do is find a sync point in the first clip and add a numbered clip marker to that point (for example, a camera flash or a music hit), and then edit it into the sequence. I do the same for the next clip(s), using the same numbered marker, and add those into the sequence. When I've added all the clips, select them all, and go to Clip > Synchronize > Numbered Marker, selecting the numbered marker that is common to all of the files. Once you hit OK, all of the clips will be synced around that point.
    Definitely easier than looking at a four-up display and trying to figure out which one is which, IMO.

  • Video Encoder can't read MPEG-2 video track

    I've recorded some MPEG-2 videos from a new Sony camcorder,
    and I can't turn them into FLV files using Flash CS3 Video Encoder.
    Each time I open the settings window, it says "This file has no
    readable video track."
    However, the mpeg's play fine on ALL my media players (Real,
    Windows Media Player, etc.).
    I've found a workaround -- I have to use some freeware to
    convert the MPEG-2 files into MPEG-4 files, and then the encoder
    can read them. But I'm still mystified as to why the Adobe encoder
    won't read the MPEG-2's.
    Any ideas?
    Peter

    I wrote an article on MPEG-1 and MPEG-2 usage in Flash Video
    encoders on Community MX. It's a free article, and it might help
    you get your MPEG-2 encoded without any transcoding to MPEG-4. If
    you have any questions after reading the article, let me know:

  • Syncronize movie w/ separate sound/video track

    I need to embed a movie into a flash-file (there's only the
    movie with sound in the project).
    at importing the avi, I had to separate the sound-track from
    the video-track because I needed to add an improved version of the
    audio.
    Since I don't know much about Flash, I put the Movie into the
    timeline of a layer and then I put the new audio on top of it.
    Now I have the problem, that on every machine the movie is
    ending not at the same time like the audio.
    Is there a way to synchronize them without the need to
    reimport the movie? does loadMovie help? (Reimport of the movie
    with joined tracks is a pain because I would need to redefine
    import-scale and -clipping dimensions on 5 movies.)
    The Flash-movie should be compatible with as many players as
    possible, I think the minimum therefore would be player version
    6?

    You can move clips by frames on timeline by using the keyboard.
    First select the clip you want to move, then hold down the option key and press either the left or right arrows.

  • Long load times for large video tracks

    Is there a recommended file size to stay under for video tracks in iTuens U? I know the hard limit is 500Mb per upload, but it seems as though any file that is more than about 10 minutes in length takes upwards of 10 minutes or longer to load. A short video (under 5 minutes) will load immediately. Is iTunes content not really streamed?

    No, it is not streamed. But iTunes U isn't setup to be a streaming service. If you sniff packets (I didn't want to, but our security guy made me because of a local issue ... long story), you'll see that content is grabbed by way-of-an HTTP GET. There is a certain sense to that ... iTunes and iTunes U are, effectively, aggregators of content. You can get iTunes U to stream ... sort of ... but it is not a true streaming service (and, in fairness, it wasn't designed to be).
    There is a trick you can play with encoding ... I don't have my notes with me (someone will remember) ... wherein you can ask that content be encoded to play as quickly as possible ... "instant on". There are a couple of apps, I believe, that help automate the process. It is not the same as streaming, but is helpful in situations in which you want a streaming effect.

  • Lots and Lots of video tracks...

    Hello Ya'all:
    Just reporting some bugs/discoveries I made in FCP 5.0.3, when using storage which is almost infinetesimally fast. I know FCP supports a maximum of 99 video tracks, but I wonder how many have actually been tested (realistically): Here's some problems I have when doing lots and lots of video tracks:
    Qty. Description
    Up to 10 Fine - no problem.
    12 Program intermittently crashes with no error, when
    sitting idle.
    14 The scroll bar on the right side of the video
    portion of the timeline stops drawing properly,
    but the crashing above goes away.
    16 Crashing is back - scroll bar still not operating
    properly.
    20 Crashing stops, but scroll bar still not drawing
    correctly.
    24 Same as above.
    25 Seem to have hit some sort of maximum, as the
    video portion of the timeline header turns red.

    I rant for lots of reasons...as does Jim.
    I rant when someone with NO CLUE as to the post production process tries to tackle a complex process thinking that FCP is easy. Especially when said people, who previously edited home movies or short films on FCP, suddenly think they can edit broadcast television.
    I rant when people think a simple plugin will edit for them, or suddenly make everything ready for broadcast.
    I rant when someone assumes that FCP can do something it cannot, and is mad for FCP not being able to do it.
    I rant when people don't do their research, buy gear, shoot hours and hours, only to find that it won't work on ANY system...and they blame the system for not working with the new gear, even though the gear came out AFTER the system.
    But mainly I rant for the first reason. Too many people think that editing is easy and that they can just buy a G5, monitor, camera and a few books and be ready for Prime Time. No no no. Even Robert Rodriguez, the ultimate film rebel, took a long time to learn what he learned. I have spent a large part of my career learning post production...broadcast standards, specs, color correction, show timing, audio post...not to mention the art of storytelling. And it really gets on my nerves when someone thinks that they can take an Mac Mini and camcorder and edit a broadcast show...and get angry at Apple for things not working properly.
    Get the proper tools. Get the proper training. Cut your chops by editing a lot and a lot and a lot. Research everything before you buy and jump into a project with a huge deadline. I am venturing into HD...I start editing next week...I have been researching the topic since July and am STILL testing gear and my workflow.
    I am sure there are plenty more reasons I rant, but those are the ones off the top of my head. I just have little patience with people who think that editing is easy and instantaneous. It is hard and time consuming, and if I didn't love it to death I wouldn't do it.

  • How can you collapse several video tracks into one track?

    Hi, I have a stack of five video tracks that make up an identification placard for a speaker. I need to create motion on this, but don't want to have to do it to every track individually. I believe there is a way to incapsulate all five tracks into one track. Does anyone know the method of doing this?
    Thanks so much, Bob

    Select the tracks and type Option - C, or go to the menu Sequence > Nest Item(s).
    That will nest the tracks in to one clip on your timeline. If you need to make changes in the nest, double click on the nested clip in the timeline and it will re-open the tracks that have been nested.

  • How do I get the audio track to stick with the video track?

    Whenever I move or cut the video track I want it's audio track to move or cut with it, how do I get them to stay together so I don't have to do double work?
    This should be an easy one...Let's see who can answer first.....ready, set, GO!

    Sounds like Linked Selection is switched off. Check the button in the upper right of the timeline window. Shift-L will toggle it off and on.

  • ERROR message (iDVD) 'no video tracks selected'  where is 'SHARED'

    (I think everyone's asleep on the iDVD boards, so I've taken the liberties of posting here also, sorry.... ssshhhhhhh....)
    My first time using iDVD (it's 5.0) --
    Exported sequence from fcp as QT.....
    Dropped into into 'drop zone' hit 'burn', and get "no video track defined"
    I searched this forum (iDVD) and it seems I need to tweek "shared" setting.... since I made the sequence in fcp (not iMovie), where is this 'shared' menu?
    Very perplexing...
    Thanks.
    Mark

    Here'w what Ken says from his article detailing iDVD:
    Once you have set all your markers, set an in and out point on your Timeline, File Menu > Export. From FCP 4.5 and FCE 2, select QuickTime Movie (not 'Using QuickTime Conversion').
    There is an option in the Save box, "Make Self contained". If you uncheck this box the movie that is generated will consist of pointers to your media. The export process will happen quickly and the resulting file will be small in size. This is a good choice if you will be using iDVD on the same Mac as your editing application. If you chose to "Make Self contained" the resulting movie will contain all of the media, it will take longer to export and the file size can be quite large, (about 22 gigs for a 100 minute movie). If you will be moving to a different Mac to work on iDVD then you'll need to have your movie be self contained. In either case, leave 'Recompress All Frames' unchecked.

  • Looping a video track with escape -- Bug or Pilot error?

    [The next 2 paragraphs are a repeat of my previous post. I'm including them for context.]
    I'm working in DVDSP 4 and have encountered a few "anomalies". I wanted to see if I am doing something wrong or if I have found a bug. I will break this into two posts because they are two different issues.
    Basically I am creating a DVD that will back a live presentation. The video track is timed to approximate the length of the presentation. But I want to have several "escape hatches". If a segment does run a little long then the presentation will dump into another track that has a still image and a background music track. I don't want to pause the play, because I want full-field video and audio. I also want to advance through the presentation by simply clicking the NEXT CHAPTER button.
    [/End repeated section]
    So the other problem with looping a still on a video track is escaping the loop. I've set this track's END JUMP to go to the "Chapter 1" marker of the current video program. (It's the only marker on the this timeline.) I've targeted the "Next Chapter" button to return me to my main timeline. Whether I simulate OR burn this DVD program I get the same results. The playhead does not jump tracks. Instead it returns to the start of the current timeline and begins playing again.
    Is this supposed to happen? DVDSP lets me assign all these actions, and the manual and support seems to indicate this should work, but it doesn't. Not sure if this is a bug, a problem with the DVD spec, or simply my lack of knowledge. (please help)

    Houghts & Aldershot -- thanks for your reply. To add a little clarity the project goes like this:
    The MAIN track is 20 minutes long. If the speaker finishes a section early, he can "NEXT" to the next section (next marker). If he runs long, when he gets to the next marker the dvd will dump him into another track (Lets call it WAITING TRACK) that will "hold" (with some music) until he hits NEXT again. So far this all works.
    The problem is getting OUT of the WAITING TRACK loop and back to the MAIN track. Putting a second marker near the end of this track (as Aldershot suggests) will jump me to the end of WAITING but how do I get back to the marker in MAIN? Can I just set an end Jump to go back to the marker I want in MAIN? Will the presenter then have to hit skip forward twice? (I guess I'll have to try and see.)
    I guess I could target this marker in main with the MENU button, but then the presenter would have TWO buttons to worry about. I'm trying to make this as zipless as possible.
    By the way, if I don't loop the WAITING track back to the first marker, this scenario works. The problem only arises if I loop back to Chapter1. Making the end of the track an infinite hold looked to be a promising option. But it seems to put the player into pause. The user must hit PLAY and then NEXT. Two buttons again.
    I'll keep digging and follow up as I learn more.

    Hallo Mylenium,
    Du hast absolut Recht! Meine Anfrage war derart allgemein, dass Niemand damit etwas anfangen konnte. Ich habe das Problem mit dem Adobe-Chat lösen können, es hatte mit meiner AMD-Grafikkarte und einem anderen AMD-Gerät zu tun, deren Treiber aktualisiert werden mussten! Das nächste mal werde ich mich deutlicher zu verstehen geben;-)

  • How to watch flash based videos without adobe flash installed using Safari

    How do I watch flash based videos without adobe flash installed using Safari?

    Once you have Chrome installed, activate the Develop menu in Safari (go to Safari Preferences > Advanced > Show Develop Menu). You then will see under the Develop menu the Open Page With option and Chrome will be listed there.
    So each time you open a page with Safari requiring Flash, you use that menu option to open the same page in Chrome.

  • Audio and Video tracks don't go up/down together EVEN when linked selection is checked!

    I'm sure this is something really simple but I just can't figure it out. And it must be a button or a option that I've checked because it didn't use to do that a few days ago.
    Basically, I have a clip on the timeline which has a video and an audio track. I want to move the video clip up to the next video track but I want the audio to move down to the next audio track too. Right now it's not doing that. Only the video file moves up to the next track and the audio clip remains in the same track. How do I fix that so that however many tracks I move the video up by the audio goes down by that same number of tracks?

    Not sure how other NLES manage it but I think it would be a pain if audio  automatically followed video in this respect.  eg Blocked layers b'cos something is already there.
    FCP &, and earlier behaved that way. I prefer the way Premiere Pro does it. You often do not need to move the audio to a different track when you move video to another track. I want to control the placement of audio and video separately now.
    Thanks,

  • Brightness differences between Menus and Video Tracks

    I am trying to learn DVD Studio Pro 3.
    My project has a "roster" menu that leads to several submenus. I want an animated transition from the "roster" menu, to each of the submenus.
    I built each of the animations in After Effects. They all start with the same first frame -- the "roster" menu. Each animation has a different ending frame -- one of the submenus. I rendered the animations as QuickTime movies in After Effects.
    Also in After Effects, I used the "Save frame as" menu to make a flat .PSD file of the first frame (for the "roster" menu,) and each end frame (for the submenus.)
    I imported all the files into DVD Studio Pro. I laid out the menu structure, drew buttons, and connected them all the way I wanted. Each button on the "roster" menu points to the start of a track, and the End Jump of that track points to a submenu.
    The logic of all this works the way I expect, both in DVD Studio Pro's simulator, and on a burnt DVD. However, there is a noticeable brightness difference between the video tracks and the menus.
    How can this be, if they are derived from the same graphic source?
      Mac OS X (10.3.9)  

    There could be a ColorSync issue with the PSD. Either take it into Photoshop and try no ColorSync (or a different setting), or take a single frame of the video and make it last a while, and use that as a motion menu.
    I have cured these differences both by changing the ColorSync settings of the PSD, and also by setting the monitor to generic RGB. That was enough to make DVD SP ignore the ColorSync settings in the PSD I was using.
