Transition from video to video on command

Hey, some have answered this question partially already. I'm doing a dinner and presentation so I need to have a video loop during the dinner, then dissolve to different videos as the awards go on. There will be a video, then a background video as the presenter announces the awardees, then another video, then another background video for the next presenter, etc. Since they can take as long as they want to speak, I can't have a preset time for the videos to transition. So far keynote freezes the frame of the video when I advance the slide and dissolves to a freeze of the first frame of the next video slide, but I need to have the video keep playing so the dissolve is seemless. Otherwise I'll have to rent a mixer and hook up several DVD players in order to get the same effect. Is there a way in keynote to do this or is there another program that can do the same thing? Thanks for any help.

You could try Pro Presenter (it can do what you want, even though it's made for displaying both video and lyrics for churches). http://www.renewedvision.com
They also make an incredible app called Pro Video Player. It's expensive, but it's made to replace units like the big Edirol video players. It definately can do whata you want, but as I said, it's expensive.

Hi - also new to the forums - I am trying to do the following:
I have a slideshow with slides of people, then a slide with a video of someone talking about the person, then more slides, etc... I want to have my playlist play then pause (or fade) so that it does not conflict with the audio from the video clip when it (automatic slide show) transitions to the slide with the video - can I do this and if so how?
thanks,

How do I transition from video to picture?

I have a video and I want the video to fade into the picture. The video is a painting and then the picture is the real image that they painted. How do I fade into the picture to look like they painted the real image?

What happens when you put a cross dissolve between the two?

Occasional sharp 'beep' sound when transition from a photo to a video

Hi guys-
I've been looking everywhere trying to solve this without any luck (doesnt seems like many out there with such problem).
I'm compiling a video for a family event (comprising of still photos and video clips) but i noticed that occasionally when the compilation play from a still to a video clip- it'll emit a sharp 'beep' noise.
This is what i checked and confirm so far-
1. it happens only when moving from a photo to a video (but not always occur).
2. the video clip has original sound volume set to 0.
3. original video clip does not contain the beep.
4. background song does not contain the beep.
5. not all transition from photo following video produce such beep.
6. the beep still happens even with the background song removed (technically no voice element in the project).
Can anyone share any ideas/experience around this?
Thanks in advance!
- Ryan

Does this happen just when playing in iMovie, or after you've rendered the video into a finalized stand-alone file? If you haven't exported the movie yet, I'd try that and see if the beep is still there.

Hi I've noticed many of the standard video transitions from CC didn't carry over to 2014 can these be imported?

Hi I've noticed many of the standard video transitions from CC didn't carry over to 2014 can these be imported? 3D,2D its very much bare bones now and I was fairly used to using several of those. The ones I purchased carried over. Thanks

Kitz reports that my IP profile should be at 1 mbps (http://www.kitz.co.uk/adsl/IPprofile.htm) but I was syncing at about 600 kbps earlier today before I accidently reset my router (pulled a wire I didn't mean to pull. ) After the reset my sync jumped to the current 1184 so it's probably still readjusting, noise started at 9 dB but rose to about 20, before rising to 24 later tonight. I'm pretty sure my house doesn't have any internal wiring issues, but I suppose it's better safe than sorry. Regarding why my noise margin is currently so high, I don't know for sure but when I was first having issues I'm pretty sure I remember my IP profile being stuck at 135 kbps while I was syncing at about 1 mbps, I don't know if this could have contributed. My IP profile seems to be behaving fine now, though.
Anyway, thanks once again,

This is how you extract frames from video

right then, in answer to many posts about how to get the individual frames from video, here is my solution. it seems to work with mpg files but it doesnt seem to work with any of the avi files i tried. not sure why it doesnt work with those. i have modified javas frame access.
nothing is displayed except it prints which frame it is doing.
if anyone wants to improve it, please do. i still dont understand fully how it works so i probably wont be able to answer many questions about it. anyway here it is:

The quality of the produced video from this example is very poor.
It comes to huuuuge surprise the following fact.
If you comment the line where you set the PostAccessCodec, the chain of the codecs is:
MPEG-1 decoder -> YUV2RGB -> Direct Draw Renderer. ( The one used from the system to decode and render)
If you run the example purely as is above you get the following sequence(as long with the poor quality):
MPEG-1 decoder -> YUV2RGB -> Windows GDI Renderer.
So you say lets set another Renderer. So
you add the following line videoTracker.setRenderer( new DDRenderer() )
What comes to a surprise is the following chain of codecs:
MPEG-1 decoder -> YUV2RGB -> Post Codec -> Java RGB Converter - > DDRenderer
The quality now may be perfect but video runs to slow. The surprising thing here is that even though we have set the outputFormat of the PostAccessFrame codec to RGBFormat the system converts it again to RGB through codec Java RGB Format.
After searching a lot and reaching the conclusion that the deference between the 2 RGB's is their sizes I sudently was brought in front of a method called grabFrame(). Bels started ringing inside my head. Starts were comming up. Looking at the definition of the class com.sun.media.renderer.video.DDRenderer I descovered that this damn class implements the FrameGrabbingControl Interface. What the f.....? The problem that consumed 4 days of my life and multiplied with 10 to give hours has finally come to an and.
Summing up the solution for grabbing frames is this!!!!!
DDRenderer renderer = new DDRenderer();
videoTrack.setRenderer( renderer );
and in your actionPerformed implementation
FrameGrabbingControl fr = (FrameGrabbingControl)renderer.getControl( "javax.media.control.FrameGrabbingControl");
Buffer frame = fr.grabFrame();
The following stuff ...are stated in FrameAccess

How can i add a transition to video when using pinned audio without loosing sync

Everytime i try to add a transition to my video after adding audio from an external source the audio becomes unsync,( it doesn't matter if i pinn the audio or not) any solutions or worked around?
I'm using Imovie 11.

Try this...
Click EDIT/TRANSITION OVERLAP/HALF. This will maintain project duration.
Normal transitions take half the frames they need from each adjacent clip.
If you choose HALF, it will take the frames needed for the transitions from the unused portion of your event clips. For this to work correctly, you will need to have unused frames available in each clip. If your project clip uses the frames all the way to the beginning or end of the event clip, there would be no frames to borrow. You also need to make sure that there is no embarassing footage in the unused frames that will be now used in the transitions. If you carefully edited out Aunt Judy picking her nose, these frames of Aunt Judy may show up in the transition, if they are adjacent to a project clip with a transition.
There are good diagrams explaining this in iMovie/Help.

If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

Themes / Ken Burns effects don't render, Transitions and Video FX do render

Topic pretty much says it all. I'm working on some family vacation videos, and thought it might be nice to apply some travel themes to some sections of the video.
The red "rendering" bar that's supposed to crawl along the bottom as it's rendering, and then disappear when done, is dark red, and never fills with the bright red indicating that it's actually rendering the clip.
iMovie's at the latest version (6.0.3), and I've tried this with a number of projects, with no luck. Transitions and video effects work like a peach, so it's just something with themes and the ken burns effect on pictures.
I've deleted the imovie.plist, and repaired permissions.
I should also note, the preview, when dropping clips onto the drop zone(s), display's properly. As does the ken burns effect when setting up it's duration. It's when you apply the settings, and it drops the clip onto the timeline to start rendering it, that's where we hit a snag.
This is on the internal drive, Mac Extended (Journaled) format, there's about 40GB free space. I've emptied both the system, and iMovie trash. I've tried deleting the FontCollections folder.
I'm just rambling off suggestions I've tried from the various threads I've been gleaning in hopes of finding a solution to this.
When I started these projects, I chose DV Widescreen, as everything I film with my DV camcorder (Panasonic PVGS59) is set to widescreen.
I've even tried manually splitting the clips, so that the part(s) I want "themed" are only as long as the theme duration, hoping maybe it was choking on a longer clip (say around 1 to 2 minutes), when all it needed for the theme was about 4-10 seconds. Exact same thing, dark red "rendering" bar, but no bright red bar showing how the rendering is progressing.
I've dug through about 32 pages so far, still going and not finding anything that's actually helping. It seems though my issue is quite similar to others', it's unique as nothing that's worked for others is working for me.

Hi, Nice to be here, despite the problems!
Last night I reinstalled iMovie from the recovery disk and even manually deleted all plugins and prefs beforehand. It didn't make any difference in either my account or a new user account I set up. I repaired all the disk permissions again and also once again deleted the iMovie plist, all to no avail.
I had a software update flagged on Monday night (which I downloaded), the problem has only been since then. The other software flagged for download included a battery update and a SuerpDrive firmware update. The SuperDrive update seems to fail to operate. It would try to run it on startup but would advise that the program could find a device to update? Strange. I deleted the .pkg and also the program from nmy startup items.
So, with the version of iMovie rolled back to the original one off the recovery disk, I would have hoped that it would have started to work, which it hasn't! I subsequently searched for software updates and added a couple, one at a time to see if that would help (restarting every time). That didn't work either!
What on earth is there left to do, despite a full reinstall of Mac OSX?!
I wonder if this is an emerging problem following the latest seemingly recent software update for iMovie?

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.

[SOLVED] How to Crop an MP4 Video via Command-line?

I have ffmpeg, mpg123, and mencoder. Does anyone know of a way I could use any of those to crop an mp4 video via command-line? I am trying to take off the black space above and below a video. Thanks in advance!

I don't think it's possible to crop without re-encoding, but you can crop from the command line with ffmpeg and mencoder. Not sure about mpg123 - I think that's for playing audio but I could be wrong there.
Anyway, with ffmpeg you can do cropping by using -croptop, -cropbottom, -cropleft, and -cropright. So if you wanted to crop 16 pixels off of the top and the bottom, your command line would look something like this:
ffmpeg -i <input file> -croptop 16 -cropbottom 16 <video encoding options> <audio encoding options> <output file>
With mencoder you use the "crop" video filter, like this:
mencoder <input file> -o <output file> -vf crop=320:208:0:16 <other options>
where the "320:208:0:16" means that the resulting picture is 320 pixels wide, 208 pixels high, and the 0:16 is the x,y position of the cropped area.
These command lines are just really very basic examples - ffmpeg and mencoder have a LOT of options. Way too many to explain here. If you don't believe me, just try reading through the mencoder man page sometime. (There's an online version of it at: http://www.mplayerhq.hu/DOCS/man/en/mplayer.1.html)
Hope this helps!!

Where Is PS CS3's "Frame from Video Grabber"?

In Photoshop Elements 2 there was an excellent "Frame from Video" tool which enabled you to play video clips and easily navigate to the exact frame.
You then pressed a "Grab Frame" button and the job was done.
I can't find this item in PS CS3 Extended. The only thing I can find is the "Import Video to Layers" command which isn't quite the same.

Thanks a lot ekim wahs.
Why do I keep getting this image of a mirror .............. ?
Your information (together with a few things I have managed to dig out) has helped clarify the situation.
There are certainly more possibilities than in the old PSE 2 but I tend to like simple things ......... they go better with my simple mind.
Thanks again !

Splitting Audio From Video

Hello
I'm having trouble splitting audio from video. I currently have Final Cut Pro 6 from the final cut studio package, and my issue is that my audio is not synchronized with my video. The audio is coming in too early for the video and the voices of the people in the video do not match up. How can I fix this problem? How can I move the audio without moving the video as well?

Select the clip and hit command L to separate the tracks.
The real issue is why the footage is out of sync.

Importing frames from video help please

Why is photoshop elelments 9 not recognizing .wmv or .avi files when trying to import photos from videos. I have used this feature before without problems using .wmv videos, why did it quit working all of the sudden?

When something goes awry, start by resetting the preferences. Quit the editor, then restart it from the button in the organizer or the button in the Welcome Screen, whilie holding down Ctrl+Alt+Shift (command+option+shift on a mac). Keep the keys down till you see a window asking if you want to delete the settings file. You do.
However, having said that, are you sure these wmv files are the same as the ones you did before? Frame from video doesn't work with high-def videos, for example, and it's not great with long ones, either.

Removing camera flash from video

Is there a way to remove camera flash from video clips within PE8? If not natively, is there a plugin that can do this?
Thanks,
Steve

Here are the best answers that I can offer:
1) why do you go from Premiere Pro to Premiere Elements?
Actually, about 90% of my work is in PrPro. The rest is in AfterEffects, PrE and other NLE programs. Basically, I use those, including PrE, when they do something better than PrPro. PrE will accept a broader range of formats/CODEC's, than will PrPro, so I use it to Import those odd Assets, and get them ready for PrPro. Same with CyberLink's PowerDirector, and Magix MovieEdit Pro.
2) How do you synch the audio and video (I'm guessing that you record off-camera). I synch it by eye and ear and it can be tedious. I don't have time code synchronized equipment
Most of my shooting is actually done with camera audio capture, though usually through either a shotgun, or wireless mics, attached to and recording to the camera's tape. When I do separate audio & video capture, I slate, so that I have the visual and audio sync. When I am faced with having to do manual sync, I will look for the visual and then the accompanying audio, and just nudge and listen. This ARTICLE will give you some of the mechanics of the process.
3) I don't know much about DD 5.1 SS and this is just from the point of curiosity at present, can it be a problem keeping long clips in sync?
I do not record to DD 5.1 SS, as that is a very expensive and technically challenging process. It takes six well-designed and well-placed mics, a multi-channel recorder and a mixing panel, run by a skilled tech. My DD 5.1 SS Audio is with regard to the music for my Projects. Some of it is recorded as 6 discrete channels and then mixed, while some is faux 5.1 and is "created" from 2-channel source material.
Much of the work from Hollywood is actually faux 5.1, in that the source material is seldom recorded in 5.1. Most is stereo and mono, and is blended from myriad sources. These can be SFX, dialog, ambient audio. Most of those are mono TO separate them out from any other audio sources. Narration is a good example. Few audio techs, would consider using a stereo mic for narration and would choose a very directional mono mic, so as to better reject other audio signals.
Now, I can take a mono SFX file and pan/fade (not in the terms of a "fade" Transition, but front to rear location) it across/around the sound stage. I can place that bumblebee anywhere that I want, when I want it with 5.1 SS Audio. I'd almost always work with mono sources, so that I have the pure signal with no clues as to the source location - I set those in mixing.
I must add that with regard to mixing of music, there are constraints on doing faux 5.1. If the material was not recorded on multiple tracks to begin with, the RIAA, and other organizations, greatly frowns on creating a 5.1 "master." That came after the failed quadrophonics experiments from the '70s/'80s. With Hollywood's music, the recording IS done multi-track in the studio/symphony hall, so it IS multi-track and just gets mixed down to 5.1 Audio. This will be about the only time that the audio is done multi-channel in recording, as few environments lend themselves to doing 5.1 during the initial recording. There are exceptions, like live concerts, but that is almost a genre unto itself.
Sync, in and of itself, is not difficult to maintain, but so much depends on the recording equipment. Many, using separate cameras and recorders, often find that there is sync drift, and need to establish the % of "cure." In the old cine days, we hooked our camera to the Nagra recorder, and chose which unit's crystal clock would establish sync. Then, we had a cable between the two. Nowadays with digital, it seems a bit more difficult. There are several recent threads in the PrPro forum about the sync drift between pro-level cameras and recorders. One user has found that altering his recorder's output by 104% fixes the OOS issues. Others need to test critically. The sync clocks in different equipment just does not match up perfectly, and there is usually no universal crystal clock that overrides the internal ones - like in the "good old days."
Hope that this helps. If I missed something, please let me know,
Hunt
