Drop Zones: Video and Alpha Channels

Is it possible to create a drop zone where the asset is a video clip that contains transparency by way of an alpha channel such that portions of the video allow for the background image to show through?
I am familiar with setting up drop zones and custom shapes and I have used static images with transparency, but I've never done the same with video.
I am away from my system right now or I could test this myself. Thanks in advance for the help!

hi
depending on how complicated your shot is, you may be able to get away with simply placing the image within the frame on top of the background shot. Then resize down to fit. You may then need to tweak its corners using the corner pin tool to get it to sit in the right perspective plane. You may find you need to soften the edges of the top layer image so its not so sharp and hard. For this you probably would need to add a mask and soften its edges. Then you might need to add some noise and/or colour correction to make it sit naturally with the background image. and finally if there are any shadows cast over the picture frame you will need to add them back over the new image. You can use a black shape, with its opacity cranked down with a blur filter on it.
The manual describes all of these process pretty well.

Drop Zone Video Preview

I've gone into settings and changed the timeframe for motion but the drop zone video still plays 30 secs, but I only want it to play for 5 seconds, does anyone know what I'm missing.
Thanks

Hi
It is at least possibly to use some buttons like this - But to get this right I had to make special button movies from the big original movie.
My problem started when I used the original movie that I could not go back far enough for the last buttons and not precise enough either - so by making the small button movies I got 100% control.

Trying to figure out how to use a video's alpha channel to define its hitspace for a button

Hello, I'm trying to figure out how to use a video's alpha channel to define its hitspace for a button. I would greatly appreciate anyone's help with this.

Currently I'm doing an image sequence inside of a movie, and putting the movie in the button. I hope that's what you're asking. Not sure if I entirely understand your question. (Been a little while since I used the interactive side of Flash)
Anyway if you have a specific process that you personally do that works I'd happily conform to your solution.

Can someone point me to a tutorial on image masking and alpha channels?

Goal is to make a picture in a picture frame become a moving image.
I am trying now to figure out how to make a hole in a video by subtracting a 16x9 sized rectangle.
Thanks.

FCP X / Motion 5 Drop Zone Video Freeze Frames Only!

Hmmm, well, I've followed the other discussions here regarding what appears to be an on-going issue with videos not playing (freeze frame only - usually the first frame of the clip) in a Drop Zone. I'm using the latest versions of both FCP X (10.1.1) and Motion 5 (5.1). I created a video generator in Motion with 15 drop zones for use in an open for a project I just started on. These drop zones are sliding left and right in three bands across the canvas. I can't get any of them to display moving video. I've used drop zones before and had some success with getting video clips to play in them, but in this case I'm batting zero.
Has anyone found a way around this problem? I may just import the videos into Motion and render them there since this open more than likely won't ever be used for any other project; nevertheless, I'd like to be able to use the Motion 5 template as it was designed to be used.
Thanks.

The good news, Russ, is that I've made some progress! To say that using Drop Zones can be a bit quirky is an understatement! Nevertheless, your Pro Res hint seems to have fixed my issue. I've been recutting the clips from the master archived files and saving them as Pro Res 422. The file size is considerably larger that the H.264 files, but since it works I guess I won't argue that point! :-)
I need to do a bit more investigation of this next point, but it also seems as if I need to move a frame or three into the clip before inserting it into the drop zone. I had just been taking the clip and dumping it in as is. When doing that I noticed that in some cases the clip either didn't play (freeze frame) or it started at some random (or at least what seemed to be random) location within the clip. However, since I moved the start point in 2 or 3 frames (end point doesn't seem to matter) so far, at least, the clip plays every time and starts from the proper point.
I don't know if this mattered or not, but I completely deleted the library with the project and event that I was originally trying to edit to. Since it wasn't working anyway there is nothing lost and I felt it was worth starting the project "fresh", so to speak.
So far I've only re-clipped and inserted 5 of the 15 drop zone videos but for now, at least, they are all working!
Thanks again for your help and suggestions.

Problems with Apple ProRes 4444 and alpha channels in Motion 4 after upgrade to Snow Leopard. Has anyone seen this?

We've just now upgraded from Leopard to Snow Leopard and are having a problem with Apple ProRes 4444 and alpha channels in Motion 4. A clip with an alpha which keyed perfectly before the upgrade, now will not key. If I convert the clip to the Animation codec, it keys perfectly. If I export the Motion project as a ProRes 4444 self contained movie, it will key when brought into FCP 7 but if I import the project into FCP 7, it will show the key in the viewer but not the canvas. Has anyone seen this or have any suggestions on how to correct this? Is it a bug?
Thanks,

Motion 4.0.3
It just doesn't seem to recognize the alpha at all.

Custom drop zone shapes and button shapes

Are there any packages out there of designer created drop zone shapes and botton shapes? I am learning how to create my own, but I'm fairly new to design programs such as Photoshop. Are there designers who have created ones, and are they available to download?

why pay someone for this when its so easy to create your own custom assests?

How to link video and audio channels of multiple clips

Importing iMovie08 sequence via XML ends up with unlinked video and audio channel (only one of the stereo channels; see other post).
It is possible to link each clips audio and video track individualy.
Is there a way to do it in batch mode for all the clips in de timeline??

1. After selecting the in points on main audio and one of two video tracks, the "merge clips" is greyed. Yes,in case you're wondering, the audio is on the HD.
Your use of language is confusing me I'm afraid. You opened the AIFF file and set an IN then opened a QuickTime movie and set and IN and then with them both selected in the Browser (and the Browser the active window) that you cannot select Modify->Merge Clips... ?
I wasn't wondering anything about your audio, but now I'm wondering "What does 'the audio is on the HD' mean?"
2. The other issue is that the starting point is silent, so the only I know how to find the actual beginning is by counting frames back from the first sound. Is that what I have to do? Is would seem to me that there must be a "marker" that's not and "in" or "out" that will allow me to merge the tracks. No?
If you set an IN point in two clips you can merge them using the Merge Clips... command with the in points option. The IN points you choose can be anywhere and for anything. They can be where the clapper hits and sounds, they can be where a drum stick hits a cymbal, they can be where someone is clapping, they can be where a body falls from a building onto the sidewalk... Anything that helps you sync the sound with picture.

Captivate and Alpha channel video insertion black background

I have been trying in vain to insert a green screen video into a Captivate presentation. I used Serif MovieMaker5 to export the video as a ".mov" with the chroma key as a transparency. It works great if I want to overlay the .mov format file over another video in other SW platforms, but when I run it through the "Adobe Media Encoder" (AME), the background ends up black. Importing it into Captivate just ends up with a black box containing the subject of the video on top of the slide.
I think I've tried every setting in the AME with no luck.
I've seen this problem elswhere on Adobe forums, but I haven't seen a solution. Why the black background after encoding with the AME, and is there a setting I have missed? Do I need to start from a different format...say .AVI, but the output doesn't give me an option for a transparent or alpha output. The problem seens to be with the AME, but I don't know for sure.
Any ideas? I'm using Captivate 5 and the Serif, MovieMaker 5 editing SW. The output seems to work everywhere in the ".mov" format, but not when converted to .f4v by the AME

I actually solved the problem by trying to use the Adobe Media Encoder (AME) on CS3. CS3 only codes in ".flv." It worked fine! I also noticed in CS3 that there was a check box for including an "alpha channel." I could not find one in AME CS5, but there was an "exclude Alpha" box. So I looked, and I see that the AME CS5 was exporting the file as ".f4V." For some reason, my installation defaults to .f4v, and it never occured to me to change to a ".FLV" output. When I did, a box to "include Alpha" appeared, and the video works just fine.
One of the issues was that the format was listed as "FLV/F4V" on the "Source" screen. I just assumed that, since FLV was first, that would be the default output. I never looked at the suffix of the converted file. Shame on me! I was also surprised that the default was F4V, since FLV is more common, and F4V is supposed to be an improved version.
CP GURU Wrote: I don't know "Serif MoveMaker", but isn't it possible to export to FLV / F4V directly instead of .mov? I normally use Adobe Premier or Adobe After Effects and here I can export an FLV/F4V with an alpha channel that works well in Captivate.
Unfortunately, the Serif MovieMaker SW does not output to "Flash." It's one of the better of the "inexpensive" video editing SW offerings. Since I am only making short training courses, quality isn't a big concern. The big thing is that it be easy, and have chroma key capabilities. It is, and does, and I'm happy with it. I would love to have "Adobe After Effects" (AAE), but the cost can't be justified. I am seriously thinking about a cloud subscription, but the eLearning suite is not included, and I'd rather spend my limited budget on upgrading to eLearning CS6.
Thanks for everyones help!!!!!!!!!!

Video with alpha channel causing frame size distortion

I have a lower-third which I built in AE. The content only occupies about 2/3 the width of the frame however I made sure I exported it at the full frame size as the rest of the video in my Premiere project. Also, I exported it as a quicktime movie with PNG settings to incl. the alpha channel.
When I import it into Premiere CS4, I drop it in on the Video 2 layer over Video 1 which is the main VT and in the preview, it all seems to be appearing as you'd expect. If I hit enter to start rendering, when it finishes I find that the lower third has been stretched the full width of the frame and additionally, Video 1 has been stretched too. I know there's an option in Preferences > General to default everything to the frame size of the sequence but having that tickbox on or off doesn't make any difference.
Does anyone have any ideas what's causing it?

Windows. Alas neither of those options worked. In the end, it was terribly convoluted but I had to export the footage from Premiere without a graphics, then import the video into After Effects and layer my comp over it - then export the final version from AE rather than Premiere. It seemed a very back-to-front way of doing things but if it works...

Using video with alpha channel

I purchased a video clip from istock, the video clip is an .mov and has a alpha channel included. The video clip is santa clause over a black background and tagged at the end is a white solid of the video (I assume this is the alpha channel) How do I use the alpha channel to help key out the vidoe clip that I need. here is a link to the actual video clip I purchased. http://www.istockphoto.com/stock-video-11011749-santa-claus-with-alpha-channel-ntsc.php
Thanks Ja

As Szalam said, the b/w image can be used as a luma matte.
Also check if the actual piece of footage has an embedded alpha channel, i.e when you import it AE should know there is an alpha channel and let you know in the top of the project window when you select the element (or "interpret footage").
Alternatively just drag the footage to a comp and enable the checkerboard background to see if there is transparency. These three approaches are the same...just different ways of finding out about the alpha channel.

Drop zone video playing too fast

I am building a Motion title sequence with a drop zone for video. I placed it into FCPx as a connected clip (purple timeline box), and associated the video under it to the drop zone. It all works except the video dropped in plays super fast, far out of sync with the audio below. Not sure why.
My FCPX timline, source footage and motion file are all the same frame rate, 23.98. Any ideas?

Where can you place a marker en set the project loop end. Because can place a marker and then go to edith marker. But i see no list as above?
1. Deselect any objects in the Timeline. Select Mark/Markers/Add Marker. If that menu item is not available, make sure there are not layers selected in the Layers window.
2. A timeline marker will be created at the playhead. When the playhead is on that marker, the Edit Marker menu item will become available.
3. Select Mark/Markers/Edit Marker. This brings up the dialogue where you can Name, Comment and select the marker type. Choose Project End Loop from the Type menu, then click OK.
4. Drag the Marker to the end of the timeline.
Adrie, I have not encountered your problem with freezing drop zones. In the past I have had many drop zones playing simultaneously, so it should work. If you suspect that you have a bad install, you should probably reinstall it before troubleshooting any further to eliminate that possibility. I am running a fresh install of 5 on a system that has never had 4 on it.
Where did you find that tutorial? do you have a link.

Cinema 4D in AE and alpha channel

So I used C4D to render out a logo animation. I used openEXR format and made sure I checked the box for alpha channel. When I bring it over to AE, it's just the standard black background and I can't figure out how to get stuff to show up behind it. (I was trying to play with some Particular stuff.)
Anyway, I'm sure the solution is uber simple, but I'm just overlooking. Thanks in advance for responses.

Actually I did change the compression to None in C4D when rendering out of there.
Yes I'm hitting render to picture viewer, it renders, I save it as openEXR, then drag and drop the folder that it is exporting into back into AE.
I don't know C4D, but maybe the picture viewer doesn't hold an alpha channel. Is there another option to render to a file directly?
What you see in AE seems to indicate no alpha is in the file. You can grab a sample EXR like this one to verify that alpha channels do generally work.

Loss of quality in drop zone video

I am creating a DVD project where I've created a drop zone that is approximately half the size of the screen, split vertically (446 x 480 pixels). I have a video asset I wish to use in this drop zone, but no matter how I export the video (from Motion), it loses quality in the drop zone. It is not a matter of bad compression settings. It almost appears as if the footage has been scaled up from a smaller image.
Is there a limit to the resolution of a drop zone? If I scale down the image, the video looks crisp again... of course then my original layout is no longer intact.
Any idea of a workaround for this? Hopefully I am not missing something obvious.
thanks,
ak

You really don't have to use drop zones at all, just make everything part of the background. you might have to combine your motion workflow with some editing in FCP. I would suggest not using Uncompressed Animation, but simply using the DV-NTSC project preset.
You have the option to either import the .motn file directly into DVDSP, exporting your motion project as a quicktime movie, or a quick edit in FCP and export as a quicktime movie. I would suggest whichever route you take, export it as a quicktime movie and use compressor to encode to MPEG2 before importing your asset into DVDSP. This will give your greater flexibilty and control on the quailty of your final video.

Making a PDF with an image that has both spot colour channel and alpha channel

Hi I have a logo that was supplied to us as a PSD it has a transparent background, it also has a pantone colour channel. I have made a alpha channel from the transparent background as well.
The graphic looks fine in InDesign (alpha channel selected in the import options), ie the background is transparent.
But when we try to make a Hi Res PDF the result is that the graphic is on a solid white background.
If I go back to the PSD and merge the spot channel with so that it is just CMYK and try again the PDF is fine, but we obviously loose the spot colour.
How do you make a PDF with a transparent PSD that has a spot colour?

You know that annoying response from support staff? "We cannot replicate your issue". Well....
I created a PSD in CS5, with a bunch of process stuff, then loaded a spot color channel and painted in some pawprints using Pantone 172C:
Saved this as a PSD file, default settings (maximize compatibility on, but it doesn't make any difference in this situation).
Created a new InDesign document in CS5, added a gradient and some text, then placed the PSD. ID understands the PSD has an inbuilt background so there's no need to bother with a dedicated alpha mask:
Exported from ID using the High Quality Print option (PDF/1.4, which keeps the live transparency):
Re-exported to PDF/X-1a (based on PDF/1.3 which flattens transparency) - looks exactly the same. In all cases the spot channel is intact and the see-through regions of the PSD are maintained.
