Quicktime RTSP multiple video tracks

I use QT to view my camera using RTSP/RTP H.264 protocols. After DESCRIBE request, QT sent two SETUPs to confirm two video tracks and assign RTP port numbers, but it failed to display two tracks separately. In the movie property, I saw only one video track and two videos are overlaped. Please advise.

BTW, VLC player played videos well. It popped two windows to display two tracks. I wonder why QT doesn't.

Snow Leopard iTunes 10.5 will not play multiple video tracks in QuickTime .MOV files

I recently discovered that Snow Leopard iTunes version 10.5 won't play multiple video tracks in a QuickTime .MOV file.
Both video tracks appear and play correctly when playing the file in:
- QuickTime Player 10 or QuickTime Player 7.7 on the same Snow Leopard machine
- iTunes 10.3.1 on another Snow Leopard machine
- iTunes 10.5 on Leopard or Windows 7
So I think the problem is iTunes 10.5 on Snow Leopard (although I haven't been able to test iTunes 10.4).
First test file is two 640x480 video tracks side-by-side (total dimensions 1280x480):
http://160.94.17.23/demo/two-video-tracks-1280x480.mov
All I see is the first (left) video track, and not the right one. iTunes "Get Info" command incorrectly reports the video dimensions of the file as 640x480.
Second test file is two 640x480 video tracks played one after another (duration of 10 seconds each):
http://160.94.17.23/demo/two-video-tracks-640x480.mov
All I see is the first video track, and although it reports the correct file duration (20 seconds), the second video track never appears -- it simply freezes on the final frame of the first video track for the last 10 seconds.
Anyone else see similar behavior? Unless I'm missing something, I suppose I should submit this as a bug to Apple.

I have the same problem, i tried re-installing, converting it to AVC H264 but none seems to work so far

How do I copy and paste text style for multiple video tracks?

hello,
I am creating multiple video tracks with text. I want to easily copy and paste the style, i.e., Font, Color, Size - rather than having to scroll down the giant list of fonts to find the one I want, then change the color, then change the size - each and every time. This is arduous.
I tried copy / paste of one text onto a new video track, but when I type in a different word, it alters the original.
I have 9 tracks of video for 9 different texts that will pop in and out of my video. I would like to be able to copy/paste then just change the text. This would save me a huge amount of time.

I know of no way to alphabetized the Adobe Styles that come with the program.
If you had the time and the inclination, you could rename them all to force them to appear alphabetically, but that does not seem all that practical.
But, if your interest is in the Styles that you save and you do not hit the Reset File List, the new Styles will be at the bottom of the list and you can name them so that they appear that alphabetically at the bottom of the whole Styles list. But that does not address the matter of you having to scroll to the bottom of the Styles list.
In some instances, some things that you think that you cannot do in Premiere Elements obvious features, can be done by computer keyboard shortcuts. I check the keyboard shortcuts under the Edit Menu/Keyboard Customization and unfortuately did not find any that would be applicable to this situation.
As for your changes in one text file popping up unwantedly in another text file, that is because you have text files with the same name. Look into creating duplicates (with different file names) in Project Assets at the onset.

Multiple Video Tracks

With Imovie HD, just wanted to know if it was possible to have multiple video tracks and how? Also I cant seem to find the 'project library' or any 'advanced' tool section...
Cheers!!

Hi
No there are no "Multiple video tracks" in iMovie any version.
If it is the effect "Picture in Picture" Then You can add plug-ins from
third part developer that can give this.
Stupendous software http://www.stupendous-software.com
GeeThree http://www.geethree.com
cf/x. http://www.imovieplugins.com
Apple http://www.apple.com/downloads/macosx/video/ezediapluginsforimovievol1.html
http://www.imovieplugins.com/fxhome.html
But if it is real "Multiple video tracks" You need cheapest and "best" solution
is FinalCut Express.
If it is so that You shoot/record with multiple Cameras/Simultanious AND Continous
Then You would gain greatly on FinalCut Pro (Studio 2 bundle).
To work with this multi-clip function is Great.

IMovie to handle multiple video tracks?

Would iMovie also be able to handle multiple video track? (like in a split screen format, but not in the form of the template)

For example, here's how to do a split screen.

Sync edit multiple video tracks

How do you sync multiple video tracks so edits effect all of them? For example, we have 3 items in video 1, 2, & 3. If we do a cut and delete to a track in video 1, we want it to do the same thing to video 2 & 3. We have the sync track on for all video, but it only cuts & deletes in the track we are in. We're using PPro CS4 on a Vista machine.

Thank you!! That's what we were doing wrong, we were just using the Razor tool, not Sequence
>Razor at Current Time Indicator. I just tried that and it worked perfectly. Thanks again for your help!!

Multiple video tracks to line up with audio- iMovie or Finalcut??

I am trying to make music videos, like this: http://www.youtube.com/watch?v=aEzpIAdsur8&feature=channel_video_title
I have iMovie, and my main problem is getting the video to line up with the audio. I can make the audio tracks like up just fine, but then I am stuck with just one video clip to use, I cant go back and forth between different video clips of me playing different instruments because I can't line them up perfectly with the song. Help?
I have been debating wether or not to get final cut express 4, because from what the reviews say it allows multiple video tracks to be used. Would that solve my problem?

This forum is for mobile iMovie (iPhone & iPad).

Dislaying multiple video tracks in FCE

I have 3 video tracks I want to view all at once. I am an iMovie guy and only use FCE for multiple video tracks where I have several cameras on the subject at diffferent angles. I've read a technique here on how to do it but I don't understand it. They talk of shrinking the tracks to 1/4 size and puting them in separate corners. My tracks are sychronized does moving them to separate corners mean in the time line, if so there goes the timing. Could someone list a simple step by step process for this. I'm guessing they mean 3 canvas windows showing each track but I don't know how to get there.
Dual G4 1.25 ghz Mac OS X (10.4.6)

1. Double-click the topmost clip and open the Motion Tab in the Viewer.
2. Move the Scale slider down to 50% and drag the small image in the Canvas to one corner.
3. Do the same with the other clips. You will end up with 4 quarter size images in different corners of the Canvas.

Synchronize multiple video tracks

How can I synchronize multiple video tracks using iMovie? i.e.: I want to make videos of myself playing different instruments, and then use clips from each to make a music video (with the sound track being all the instruments combined). The problem is having each clip synchronized to the music.

You would be much better off with Final Cut Pro 7, as it supports multi-cam clip editing. This feature allows you to do what you want. iMovie and Final Cut Pro X don't support this type of feature.

Transitions applied to multiple video tracks

Is there a way to apply a transition, such as a cross disolve, to multiple video tracks by only placing it on the top track and having it applied to the others below it rather than duplicating it on each track below?
For example: Say I have 3 video tracks that all start at the same time. Can I apply only ONE cross disolve somehow and have it affect all 3 tracks so they disolve at the same time? Or do I have to have 3 separate copies of the transition?

If the edits are lined up you can command click to select them together and apply the transition. A separate transition gets applied to each track. If you're going to black or to a single piece of video you can also add a transition to a slug or the video on a higher track to go to that.

The point of multiple video tracks

I am half way through the Adobe Premiere CS3 Classroom in a book and the only time multiple video tracks have been used is when working with multiple cameras and still there the multiple tracks where used only to sync up the four different cameras. In the book, to determine which camera angle to show the sequence had to be dragged into another sequence that was set to multi-camera.
I see different marketing shots of the Premiere screen with lots of video tracks. How sand or why do folks use multiple video tracks? It seems that all the video transitions are between different clips on the same track, can a transition span tracks? Might there be some good videos or books that might enlighten me to some more advanced usages?
Sam

Here's an example...
Video Track 1 - Clip (main program)
Video Track 2 - Title (lower third graphics)
Video Track 3 - Title (lower third text)
Video Track 4 - Over the shoulder graphic (think "news report")
Video Track 5 - Bug/logo lower left corner
Audio Track 1 - Clip (main program)
Audio Track 2 - Music (underneath)
Audio Track 3 - Sound effects (whoosh! zing! bang!)
Audio Track 4 - Audio commentary (director, talent)
Just something to get your brain going. I've never used more than 10-15 video layers simultaneously (doing green screen work, titles, mattes, etc), and never more than about 6-10 audio tracks. But that's just me....many people need more than that to accomplish whatever they're doing.
Another thought...even though you "can" do transitions and cuts all on one track for most simple projects, some people prefer to use the track numbers as an organizational structure. Put all your cuts for scene 1 on track 1, all your cuts for scene 2 on track 2, and so on. This can be very useful for scanning the timeline and looking for specific changes in the overall storyline (whereas a single, long track would require another system of organization...either sequence markers or perhaps pure memorization).
Hope this helps!

HELP!! Multiple Video Tracks

I need to know if you are able to have multiple video tracks and once they are all lined up in the sequence you want, am I able to cut from one video track to another just like you would edit from scene to scene with 1 video track (like in Imovie)? I need to edit a dance recital with video from 3 cameras, so i need to line up the videos so they are all in sync as far as time is concerned, then switch from one video track to another without seeing the other tracks playing at the same time...in essence "mask" the other video tracks I don't want to see, but keeping all three video tracks in time and sync'd.
If yes....then I'm buying Final Cut...if no...I need something else!
Hope you understand what I'm asking!!!
Thanks, DJ

You can do it though FCP does it more efficiently.
It is a bit fiddly in FCE though Piero's free PIP filter makes it a bit easier:-

Can quicktime play an video track with multiple alternate audio tracks?

Hi,
If I have a video track with multiple alternate audio tracks (say different languages), can a user select the audio track of his choice and play in Quick time?
Thanks,
Apurva

Does quick time/ safari have this capability?
QT (i.e., the QT structure embeded in current Mac OS/device IOS versions) has the ability to switch between alternative audio tracks assuming the file is properly encoded and the compression format is supported. QT 7, QT X, iTunes, and similar app player GUIs can switch between such tracks during playback but the QT plug-in cannot. In a similar manner, devices like TV can switch between such tracks but an iPhone cannot just as an iPhone can select "Chapters" but the QT browser plug-in cannot but an iPhone file programmed with both chapters and alternate audio tracks can be played back through a TV device and access both chapters and alternative audio tracks.
What I want to use is one video track with alternate audio tracks in a set level manifest and play this using HTTP Live streaming. I'm using the manifest mentioned here :
http://tools.ietf.org/html/draft-pantos-http-live-streaming-07#section-8.7
Since I do not use playlists, I am not familiar with the approach in your example. If I want alternate audio and/or video tracks, I create standalone video files with these features built in. Nor do I use RTSP if that is what you mean by "live streaming" of content. If I want to "stream" the content, I use "Fast Start" files programmed to open in the QT player app which supports these features or create reference or QT Media Link files that do the same thing.
As you mentioned, Safari on my iPhone is playing the default/first alternate audio track mentioned but not giving an option to switch tracks.
Neither Safari nor the Video app GUIs on your iPhone have a built in switching option. The only way to switch to alternate audio tracks is to do so with QT 7 Pro or possibly iTunes before loading or streaming the video file. (Am still speaking about a standalone file here and not a programmed playlist/RTSP switch.)
However Quick time on my Mac machine only plays the audio with the the video stream and not the alternate audio track.
The QT player app GUI only switches between tracks that are stored as part of the standalone file. Basically, QT files may contain up to 99 individual data tracks. In alternative audio videos, multiple audio tracks are added to the file by an editor like QT 7 Pro but only one track is designated as "active." All other tracks are designated as "inactive." The QT player GUI allows the viewer to select which audio track he or she wants to hear and then turns off the current audio track and turns on the selected audio track. Otherwise all active tracks would play simultaneously.
Is there a way to switch tracks on my iPhone on Safari?
As previously noted, the default track can be manually changed by QT 7 Pro or, I believe, iTunes (used to have this capability) before actually loading or streaming content.
Does quicktime have this capability?
As far as I know, only with regard to stand alone files programmed with multiple alternate tracks. I am not a HTML, HTML5, or Java programmer so I assume there may be web alternatives here but they would be beyond the scope of my expertise.
Do you know any free player that can do this?
Again, I don't use either playlists or RTSP so I've never had a need to look for/use alternative players that might meet your needs. I simply find it easier to build files that work correctly in current player app/device GUIs already having these capabilities.
Or the very last option, can I build a player to do this? If yes can you suggest where/how I start?
Once again, I assume this might be possible but not part of my experience since, for my part, easier work flows are available.

Mkv with multiple video tracks

Hi. I have a load of Matroska files which contain a few (about 5) short video clips and an audio track. The video clips in each file are of the same event from different angles, so I want to watch all clips simultaneously. I have installed Perian and while the files open, I can only see one track, and I don't hear any audio. (MKVinfo tells me there are definitely multiple tracks.) Is it possible to use Perian/QuickTime to watch all video tracks simultaneously? If so, I can't figure out how, so I'd appreciate any pointers.
I've tried VLC, and while this also opens the files (and shows all tracks), it invariably crashes soon after opening.
If anyone has any other suggestions how I might solve this, that would be great too.
Thanks in advance,
wrathkeg

It could be a 'difficult' form of Matroska file. FYI Matroska is just a container like MOV or AVI, and some mkv have the video encoded with Real Video Codec (RV9 RV10). Perian+QT can't decode this, but VLC will play .mkv files just fine on OS X, as long as they don't use H.264!
It's a bit of a lottery until Matroska decide to support the Apple platform. I have found this:
http://mkv4mac.free.fr/index.php?lang=en&p=lec
which may help.
But there may be another workaround: 1. Get Info the mkv file
2. Change to extension to wmv. Save as wmv and that could work better.
Or this link may be helpful:
http://www.squidoo.com/mkv-converter-mac
Recently, a poster (ZachP14) suggested this:
"There's a program called Plex that runs .mkv files awesome on my 2.0 ghz macbook."

Maybe worth a try?

Multiple Video Tracks - Selectable

I cant for the life of me figure out how to put more than one video angle within one quicktime file and make it user friendly.
I want to create a file similar to a DVD with selectable video angles. I can get my files combined and in the movie properties turn the video tracks on and off. But how would I develop a file that a user could easily turn on and off the different video streams dependent on what they want to watch without having to open up the movie properties?
So in summary:
V1
V2
V3
V4
The user decides while watching which angle they want.
Thanks much in advance.

That's a good example and helps showcase LiveStage software but there are other issues.
Notice the example uses true "streaming" media. These files can be started from any location in the file as soon as the stream is connected.
A QuickTime user that wanted "multiple angles" (different video tracks) would only need a method of selecting a different part of the streaming file. These extra parts could be put at the "end" of the file and then simple "Chapters" tracks could link to them.
Since a true streaming file can jump to any point in the file a click on a new chapter could bet set to a different part of the stream. The same can be done with "local" files but Web based files would be difficult because of these extra tracks. The file size would balloon so large that viewing would be a real bother until the entire file has downloaded.
A local file could "react" a bit faster and would be a better distribution method. The same "chapter track" method could link to the other parts of the file.
QuickTime files can have up to 99 tracks and in, addition to chapters, can also be "linked" via the Languages menu (Alternate track in the Movie Properties window to set them).
QuickTime files can also allow parts of the file be "pre-loaded". This could help the Web based version but you would need very patient viewers.
QTVR files can also have "hotspots" that could, in theory, point to other non QTVR files. You could make a "Stage" using QTVR and set the "angles" as links to regular QuickTime movies.
Very complicated and I don't have the time or software to test any of these methods.
