Alternate between video tracks?

I am wondering if it is possible to have a QuickTime movie alternate between different video tracks. For example, we record both a speaker and their presentation. Currently, we present both side-by-side, but for portable devices, we would like to present them both in one frame so the image isn't so wide.
Yes and no.
Yes it is possible to create MOV files with multiple audio and video tracks that can be keyed to switch tracks via either the built-in language selection (in the QT Player View menu) or using sprite switches embedded in the file for use with a mouse.
No from the standpoint of possibly not serving your needs adequately. Normally the alternate track switching is keyed to changes in the audio track, so switching of audio is actually keyed to an switch in audio track. This means the simplest approach would require paired AV tracks to provide proper control. As I assume you want to be able to switch back and forth while the movie is running, there is the problem of the finite delay in the amount of time it takes to actually make the switch and the fact that sometimes the player may begin to drop frames severely. I.e., sometimes you get a smooth video switch and playback continues smoothly and sometimes you don't. Normally this is not a problem with alternate language/alternate video viewing of a movie since the user can always stop/pause playback to restore a smooth playback.
Is there any way to do this in QuickTime? I know you can set which video track is in the foreground and which is in the background, but I do not know how to alternate them. Is there some kind of wrapper or command/text track that could help us with this?
The simplest form of switching is actually built into QT. If you have QT Pro, you can set the switches very easily. In any case, I am posting a one minute sample file which you can download and to examine the switches in the Properties window (if you have QT Pro) or try playback in the QT Player to simply see how the switching works. I.e., in the case of the sample file, one track pair is keyed to "English" and the other is keyed to "French."

Transition Between Video Tracks

Is there a way to make a transition between video tracks? Or is it only possible with menu-track and slide-video?
Thanks.

Richard
Using DVDSP transition from track to track won't work the way you want or think it will. Thats not what transition in DVD were designed for. There is no solution. DVD is a linear technology and placing transitions between tracks means the laser of a player must refocus to a different part of the disc as to comes from 1 track to a transition to the second track.
Why not just make 1 track. If thats not an option then you need to re-think the title.

PRE8 - Transitioning between multiple video tracks

Hi,
I've been making Youtube vids for awhile with a web cam, and using a Microsoft app to sync my audio up with the webcam.
I now have a second camera, and have purchased PRE8 for some of the effects, and to try to sync the video closer to the audio (as well as adding multiple camera shots).
I've recorded all my video angles (5 in all) and have been trying to switch between video tracks.
I first set my audio track into PRE8, then the first video. I work to sync the two, then mute the audio track from the webcam video clip.
When I add a second video clip in, can I add it as a new video track, and then transition between them?
The book I have only uses separate video clips, all stacked onto one video track.
The problem with me doing that is, I need to pull all 5 video clips in, sync them to the audio track, and then change in between them.
Having to clip them duration wise for every transition is going to take awhile, and seems like it would be hard to get right.
Does anyone have any suggestions?
Let me know if you need more information from me to help.
Thanks!

Well, the Multi-cam feature would simplify life a bit, but there is a big difference in the cost of the two programs.
What I would do is look at a workflow, something like this:
Import your main footage, probably a Clip with a medium wide shot, and drag it to the Timeline. Now, does this Clip contain the full song, or was that recorded separately? Either way, check for the sync for the entire Clip. When you play this Clip, use the * key on the numberpad (with NumLock ON), to place Markers where you think you will want the "cut-away" shots. Don't worry if they are not exactly where you will end up placing the cut-aways, as they are just there to remind you. Now, with the cut-aways, Import one of those into Project. From the Project Panel, Dbl-click on it to open it in the Source Monitor. Set the In and Out Points to suit, and then from the Source Monitor, drag that Instance of the Clip onto an upper Video Track. Let any Audio go where ever PrPro wants it, because you will Alt-click on that Audio, and Delete it. Now, slide it along the Timeline, until it syncs up with the "master" Audio Track. You have the benefit of knowing which strings you are plucking, or which chords you are using, so it will be much easier for you. Were I doing that, I would not have a clue, and would have to use that Clip's Audio to try and match up the visuals.
Remember, that source Clip can have its In & Out Points set as many times as you wish, and you can add any number of Instances to the Timeline, where you wish, and repeat the process of visually syncing to the master Audio.
Repeat for the other desired angles.
When you are done, just add a Cross-Dissolve to each end of each of the additional Clips, as desired.
From an aesthetic standpoint, you might also want to think about doing some of those "different angles" as PiP (Picture in Picture). I have seen that treatment used very successfully with musical pieces, especially if they are instructional in nature.
Let me know if the above workflow seems logical for what you have, and what you want to do.
Good luck,
Hunt

Prem El 7: Previewing individual video tracks

Hi All,
I am new to Prem Elements 7 and have been spending a lot of time on my first project.
Some simple things are holding me up and I can't resolve with the Help centre.
I have 3 video tracks stacked in the timeline.
A key problem is how to select and preview in the monitor panel each video track.
As default, the monitor will only preview the top video track in the stack. So for me, it will preview track 3.
But I want to be able to switch between video tracks and view the content of each track in the preview monitor to help with editing decisions.
Can anyone help please?
Many thanks.

Mike
You can do as SG suggests in that you double click the video clip on Video Track 1, 2, or 3 to bring up its Preview Window.
But, consider the following when and if applicable:
a. staggering the clips of Video Track 1, 2, 3 (train arrangement) and then clicking above the Timeline to move/direct the Timeline Indicator to the video clip location to view that clip in the Edit Mode Monitor.
b. if you wanted a before/after, doing a split screen effect where you drag the Crop video effect (Effects/Video Effects/Transform/Crop) into the clips and use the Edit Efffect to crop the clips to display side by side in the Edit Mode Monitor....if find, more space to do that with 16:9 project.
As has been stated, if there are no transparencies in the clip in Video Track 3 and you are not adjusting Opacity, all that you are going to see is what is on Video Track 3 in the Edit Mode Monitor.

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.

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.

Alternate video tracks not visible

I have video files that occasionally display very different content to the primary video content, especially the first time they're played. The video stream with start to disintegrate and for a few seconds something completely different is viewable. It's also not easily repeated. Its not like pristine video content suddenly appears. The main content becomes visually corrupt or fragmented, pixilated, smeared, etc and alternate content becomes visible for brief periods.
What can I do to separate or remove the primary video track enabling the covered tracks to be visible?
I'm viewing these video files with vlc and premiere pro in a Windows 7 environment, but not skilled enough to devise a procedure to expose the underlying content.
Answering questions is not a problem.
Thanks for any suggestions or links to relevant material.

If you are willing to try anything, how about importing the file into AE?
I'm guessing the encoding is corrupt or non-standard since you are seeing the same problem in several programs.
How to get the correct frames? Well, if you are seeing different frames each time you play through it, you may have to do a manual save of each frame and then try to put them in the correct order.
I'd try to open the file in several other video programs and see if it works in any of them. Have you tried Handbrake, for example?

Video tracks disappear when changing between sequences in premiere CS6

Dear people, can you please help me find out why video tracks disappear when changing between sequences in premiere CS6.
All it shows is the audio track and it is maximized to the first frame of the sequence. Video tracks are there but hidden - although video IS showing up in the program monitor.
When I pull the tracks down in the timeline window using the dividing line between the video and audio tracks and set the sequence work area back it works fine, however it is a great annoyance having to do this every time when i swap between sequences.
Can anybody please suggest a solution to this?
I'd appreciate any help.
MD

This is the audio tracks problem i cannot overcome:
https://forums.adobe.com/thread/1586025
(basically every type of audio i drop/place onto the timeline becomes left channel only, regardless of it being music or camera-recorded audio.
In the source monitor everything plays back just fine, but when placed to the timeline - it becomes LEFT only.
Weird.... (or am I and not it)

Cross dissolve transition between multiple video tracks?

I'm wanting to cross dissolve between 2 clips, with each clip consisting of 2 or 3 video tracks (one clip is a still image in track v2, sitting above a color matte in v1; the other clip is motion footage in v1, with another cropped motion image in v2 and v3). When I put cross dissolves between the 2 clips (ie 2 dissolves, one for video track v1 and one for v2), the dissolve is "messy", showing the cropped images in v2 and v3.
To make the dissolves "clean" I can render and export the multiple-track clips, but then I have to add handles to allow the dissolve, and then it takes time to resync each clip, which is very annoying!
Is there a technique for making cross dissolves between multiple-track video clips?

Any other suggestions? <</div>
Practice and logical deconstruction.
If your original clip is 10 seconds and your nest is 10 seconds you must trim off 2 seconds of the nest to perform a 2-4 second dissolve. If that pulls too much of your original clip out of the timeline, you must add two seconds to the original clip so the nest is 12 seconds long so you can trim off the 2 seconds requried to perform the dissolve.
An easier way of accomplishing this is to stack the two nests and apply a keyframed opacity ramp to the upper track. This will help you visualize what you're doing wrong and how to add more handles to the upstream clips.

How to do a locked split-screen between two different video tracks

I'm creating two time-lapse videos and then I'm planning to to play them side-by-side in one sequence.
The way I was planning to do this was to scoot one video track over using the "center" tool in the motion panel, and then crop it on its right-hand edge to reveal the other video track beneath.
The problem with doing this however is that, as the camera gets bumped or moved slightly as the months go on, and I then have to cut and reposition the "center" location for the clip, I have to then adjust the amount of crop on that video clip since I've moved its position. This means the center split-screen location keeps changing as I move the video around.
Is there a way where I can just lock the split screen smack in the middle of the frame as I tinker with each side of the frame (video track) independently? I tried adding a split-screen transition in the very beginning to the top track, but I can't make cuts on a transition to then adjust the motion attributes.
Any ideas on how to simplify this process would really be appreciated. Originally, I thought there was no easier way to do this, but I was so blown away by all the answers to my motion effects question today (and all the things I never knew about FCP) that I thought it wouldn't hurt to see if someone out there had one more ace up their sleeve. If not, I'll assume this is one of those things that can't be simplified anymore than what I'm doing.
Thanks again guys,
Chris

Though David's Motion Tracking suggestion would eliminate alot of later finagling, you could try something similar to Reink's, without using Photoshop.
Try this...
1. In a seperate timeline, drop a Matte/Color Solid into the new timeline (using dropdown at bottom right of Viewer window).
2. Dbl-click the color solid, click on Controls tab and set Parameters as H/0, S/0, B/100. Then click the Motion tab/Crop Right-50.
3. Click the Viewer's Video tab and go to Export/QTConversion/Still Image (png) and name it something like WhiteMatte_CropR50.
4. Import that into your project.
5. Now with your two timelapse clips on V1 and V2 with in/out points at head/tails and both tracks highlighted...'Nest' the sequence...Main Menu/Sequence/Nest Item(s).
6. Next, with the nested sequence active (single clip will look light purple)...option-double click on it and and drop an Image Mask Filter on it, then drag the WhiteMatte.png clip into the 'image well' (little box that has a question mark in it). Keep the channel on Luminance.
7. Now, if you dbl-click the nest, it will open it's host sequence, that you can do your 'Motion Tab/Centering' on, without affecting the 50% split down the middle.
May seem like alot of work, but it's not really.
K
p.s...there are probably other ways to do this as well.

Can't Rename video tracks in Bootcamp

Hi,
I'm using Adobe Premiere Pro CS4 on my Macbook Pro on the Windows 7 bootcamped partition. I try to rename my video tracks by right clicking (or control clicking for that matter) but all that happens is they become highlighted or unhighlighted (or nothing if the track is locked). My right click works for other applications as well as other parts of Premiere (renaming the sequence, etc) but not the video tracks. How can I fix this?

Make sure that you are Rt-clicking ON the Track Name in the Track Header. Otherwise, you will just Target the Track. Depending on your screen rez, you might have to be very exact with cursor placement. It can be rather like finding the vertical zoom handles, between Tracks - a pixel hunt!
[Edit] Just tried this in PrPro 2.0 (obviously on a PC), and the cursor position was not anywhere near as critical, as I suspected. Anywhere in the Header got me the Rename option. Guess that I always did it right on the Track Name, and made an incorrect assumption. Sorry for that.
I've not heard of Bootcamp loosing the Renaming capabilities, but have to admit to being a PC-only guy.
Good luck,
Hunt

Toggling between video clips (not audio clips) in the timeline

Hi,
I was wondering if there is a solution to this small inconvenience I am experiencing in FCP 5. When I have snapping enabled, and press the down arrow key, the playhead jumps to the next audio or video clip in the timeline. I am trying to find out if there is a way to jump between video clips only.
Thank you
-Peter

Thanks,
Do you know if there is a way to make the up/down arrows snap to only the video cuts on the video clips in the highest video tracks in the timeline? Thanks.

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.

Audio and video track strangeness

Hi,
I have a few camera angles that have 4 audio tracks associated with them, and other camera angles that are just one track...
I was attempting to stack all of my camera angles in fcp, so that I could sync the audio up for the various angles, and then cut between them and drag various pieces to the top video track (I assume this is a standard way of working).
Anyway, so the problem I was experiencing was, I had one video track with one audio track, and then the next video track above that had 4 audio tracks connected to it... So if I tried to take a slice of the 1st video track, and move it to the next track, the audio would go ontop of one of the 4 tracks....
I thought I could solve this by locking the video and deleting 3 of the audio tracks so everything would just have 1 audio channel (I dont need the other 3 for my editing purposes)... However, it still causes the audio to behave oddly and jump 2 tracks rather than one....
How do I fix this?? I don't even understand what is really happening here.
-p

Hmm after looking at it, it seems that what's happening is even though 1 audio track is assigned to each video track, FCP thinks that there should be 2 audio tracks? So when I move a video track to the next video channel, the audio is moving down two audio tracks instead of one...
Ok, so atleast I do understand WHAT is happening, I just don't know why.

Video track luminosity blend mode weirdness

Applied sharpening to a video track and set the blend mode to luminosity (so that I could put a blurry multiplied layer in between)
Now wherever the luminosity layer finds an overexposed highlight it renders as black. If I turn down the opacity of luminoisty layer it stays black, if I switch it off it dissappears. !

Hi Chris,
Thanks very much for your straightforward and helpful answer. So, it would appear that my simplistic understanding of the Hue blend mode as 'replacing' the hue of the underlying layer(s) is incorrect. Would a fair rendering of what the Hue blend mode actually does be as follows?
"The Hue blend mode will perform a direct replacement of the hue in the underlying layer(s). The brightness and saturation of the underlying layer(s) will not be affected *unless* the resultant hue, saturation, and brightness 3-tuple would result in an illegal HSL combination, in which case the saturation and brightness of the resultant pixels will be altered to bring the HSL values into compliance."
Also, is there a way for the Info panel to display HSL values?
Thanks again,
Matt
