Rendering targa sequence with only alpha

Can I render a targa sequence with only alpha channel (RGB transparent, not black)? So that if I open a frame in Photoshop the RGB channels are transparent and only the alpha channel has content.
I'm going to use the alpha channel in another software as a mask (but it has to imported as a image sequence, can't choose only alpha). That means that if there is anything in the RGB channels I'll see it on screen where the alpha is...

I don't quite follow. Alpha cannot exist without RGB pixels, as in technical terms it's not transparency, but the blending amount between foreground (pixels in the image) and background (other pixels that will be placed below). If exporting the Alpha as a b/w matte does not serve your needs, then apply the Alpha to a black solid in a black comp and export that.

Export quicktimes as targa sequence with embedded alpha in HD

I'm receiving some HD Quicktime files tomorrow which I understand have an embedded alpha channel. I need to export them as targa image sequences, which I've never done in FCP before.
Will the alpha remain embedded in the targa sequence?
What TGA option do I choose (eg: million of colors, millions of colors+)?
Will I wind up with "high definition" targas? I understand HD Targas are just giant-sized images, is that right?
Anything else I should be aware of?
thanks

Open the Files in QuickTime Player. No need to use FCP.

Make sure to create a dedicated folder as the destination...

AME CC 2014 Rendering with only One Core

This seems to have just begun recently (within the past month) where AME CC 2014 is only using 1 core (out of 12) to render video. No, this is not the CPU Parking issue - I have made the regedit tweaks and also changed my Power option to Performance, all with no difference in AME. Premiere Pro CC 2014 renders the same video just fine using all 12 cores, so it seems this problem lies not with Windows software, nor Premiere Pro, but just AME CC 2014. Was there a recent AME update that might have included this bug?
Adobe, please look into this and resolve it ASAP. Not being able to queue up video renders is killing my productivity.

I just installed Premiere Pro CC 2014 this week and had the same problem, my media encoding time tripled (3 times longer).
The same sequence in Premiere Pro CC (Old Media Encoder ) still encoded at its normal fast speed.
Only one of my eight cores was running during encoding in Premiere Pro CC 2014.
After making the registry changes (below) all eight cores were running and Premiere Pro CC 2014 Encoder was back to normal speed.

After you have read the Adobe Forum link above, go to this link below.
This registry change is for Windows 7, I'm not sure about Windows 8
The registry link may be different but you can still look.
Than call Adobe and have their tech go to this link below.
Than have them suggest what to do.
I did call Adobe back and told them it fixed my problem and they were appreciative and said they would pass it on to all their techs.

Just a note,
I was in touch with Adobe earlier this week with this same problem.
I gave them control of my computer (from India) and after an hour the tech concluded it must be my video card causing the problem.
I am using a Nvidia GTX 560Ti, which is not a certified card. I preformed the card hack.
After getting off the phone with them I did some additional test and found that my old AME rendered my sequences with all eight cores.
The new AME CC 2014 was only using one core.
This registry change above keeps all the cores running.
After I made the change all the cores were running during encoding and the speed was back to normal.
Hope this helps,

Targa sequence, how to import it only with Final Cut

Anyone knows how to import a targa sequence, without first making it a quicktime movie with QTPP(pro)?
I know the method of the 1 frame duration of a still, I want the final cut to recognize the targa sequence as a SEQUENCE...
Is that too much too ask from such an editing platform like Final Cut? I hope NOT

do not have QTPP
I read about that way
any way to do it without QTPP?
normal QT does not allow me to export in alpha channel...as my graphics are supposed to play on top of shots not on their own...
I'm desperate, have to deliver the project 2 days from now and I'm not good in compromising with anything at all...
thanks you in advance...

Rendering Sequence with Motion 3 Template Crashes FCP

I am using a template with 8 drop zones from Motion 3 in FCP 6.0.2. The template is used about 10 times end to end with a slight overlap. As FCP renders the sequence about 23% of the way through it crashes FCP. The templates contain still images - no video.
Any thoughts? (Besides don't use templates)
Thanks!

Exporting Targa Sequence and Alpha Channel

I have a couple of targa sequence containing graphics that I need to export. One has an opaque arrow which rolls out over the film underneath. The second has solid text which will be laid over the arrow as it animates. I have run the image sequences in Quicktime, the arrow sequence comes out as a block of black and the solid text comes out against a black background instead of an alpha channel and I can't seem to manipulate them. I have FCP 6 which i thought had Quick Time Pro to handle alpha channels. What am I doing wrong, can anyone help?

hi,
what exactly are you doing?
why are you exporting from quicktime? why dont you import the image sequence directly into motion/fcp? Not saying you;re wrong, just wondering that 's all.
Have you got the export settings correct. Not many codecs support alpha channels. Your best bet is Animation set to Millions of colours +. the + is the alpha channel.
However motion or fcp should be able to read the image files just fine.

Set up After Effects CS 6 for network rendering with only a single license.

I have searched on and off a couple of days to find specific setup instructions for submitting projects to network rendering but all I can find refers to somehow installing AE on several machines in a non-license mode and, essentially, submitting a "batch" type job that get distributed, sync'd and collected. OK, I get this. But I find nothing on the details of installing on several machines.
So assuming I understand things to this point, the question is really how do you install multiple AE6 copies to systems with only a single license? I have a single license key with a CS 6 Premium Suite and would expect that I wouldn't be able to get past Activation after installing or am afraid of trying lest Adobe think I'm attempting to circumvent licensing.
Thanks in advance for any help.

> am afraid of trying lest Adobe think I'm attempting to circumvent licensing
Have no fear. Just do it. There's no risk to trying to install software on as many machines as you like. Even in the cases in which you only have a license to use our software on two machines, the worst thing that happens is that you are told to deactivate on one computer before activating on another.

Rendering Interlaced Targa Sequence - Frames Missing

I have an AE CS3 project.
I'm using a transition in my project - Dissolve - ripple.
I've previewed my comp and everything looks just how I want it.
I setup the render queue to export my comp as a Targa Sequence (24-Bit) Interlaced. The render runs fine. However when I previewed my targa sequence in both bridge and in Premiere Pro CS3 - the frames containing the Dissolve - ripple are totally black. All I see is the text layer that was above the layers that had the Dissolve - ripple transition.
As a test, I exported to a DV-AVI Interlaced - previewed it in PPro CS3 and I'm having the same problem with the AVI file.
Does anyone know why that won't render to a Targa Sequence or AVI (for Interlaced Vide)?
Thanks
FOO

I can repro this. The source footage has to be interlaced and you have to render to interlaced. I played around a little- it doesn't occur if you reorder the effects. It seems to have something to do with the animated Opacity control on the Solid Composite effect in the preset. I can also make it happen with completely different effects (Bulge and Fractal Noise), as long as the second effect has an Opacity control that is animated.
I filed a bug with Adobe about it.

Rendering sequence with Warp Stablizer

I'm getting ready to render out a sequence with multiple clips that have the Warp Stabilizer effect on them. I noticed that this time after opening the project, many of the clips with WS on them want me to click "Analyze" again, even though I've done that previously. I haven't deleted any rendered clips that I know of.
Here's my main question: Do I need to go through all my clips and click "Analyze" on each one before rendering out the final sequence, or will PP analyze it automatically when I render it out? Thanks.

Export with transparency / alpha

I am doing a green screen key, and I prefer to compose the background with the keyed foreground i FCP. I am achieving great results with DV-keying in shake, and would like to export my keyed clips with their alpha layer, so that FCP will import it with alpha/transparency.
I have tried exporting targa rgba, but cannot seem to render them out as a sequence. (Only one image is rendered, and the other frames are rendered in the same file, overwriting it).
Is this possible, either trough a video format or through an image sequence or something?
Regards, Espen Dale, Norway

You need to put special characters in the filename to tell Shake where to put the frame numbers. # is for a 4-char padded number and @ is for an unpadded number.
For example:
MyFile.#.tiff returns MyFile.0001.tiff and MyFile.0100.tiff
[email protected] returns MyFile.1.tiff and MyFile.100.tiff
MyFile.@@.tiff returns MyFile.01.tiff and MyFile.100.tiff

Keying with an alpha channel

I have a client that needs some footage that we shot over green screen delivered to them with the green keyed out and an alpha channel already in place. The end deliverable that they are looking for is the talent over an "invisible" background that they can simply drag and drop into FCP without having to key it themselves.
So my question is, how do I key out the green and an add alpha channel to preserve the "invisibility" of what was once green?
I hope that question makes some sense!
Thanks!

The most straightforward solution is to export your keyed sequences
to Animation, PNG, or JPEG 2000 using millions of colors +.
Make sure the sequence is NOT RENDERED before you export.
(In other words, if you want to render and preview to make sure it's good,
do that, but delete your render file before exporting.) The only problem
is that the resulting files are huge and will really bog down your client's
edit.
Another solution is to export two files per clip, with the second file
being a black-and-white version of the alpha channel.
To create the second clip, add the Channel Swap filter with
red, green, and blue all coming from alpha.
Then your client places the two files over each other, with
the "alpha" clip below the regular version, and the Composite
Mode of the upper clip set to Travel Matte - Luma.
In fact, if your client already has the clips, you can just
send them the alpha versions.
The big advantage of the second solution is that you can
stay in the same codec, which should make your client's
editing go a lot faster.

How to export a video with an alpha channel that can be switched off

Hi!
I'm stuck with something that I think might have a simple solution:
I need my video to have an alpha channel while still keeping all the RGB information in place too. This is for Syntheyes, which can take the alpha channel for a video and use it as a garbage matte while tracking.
The problem is that if I draw a mask around my video and then export as a PNG (with alpha), the RGB information seems to be gone even when I choose to ignore the alpha channel. I know how to edit the alpha channel in Photoshop while still keeping the RGB elements untouched, but how should I do that in AE?
Any help will be appreciated!

Okay I will answer my own question:
This worked as soon as I did a proper export as a PNG image sequence. I did my tests with only single frames by using the "save frame as file" -function, which did not work properly (the rbg information was gone).
So the simple solution to this question was:
Draw a mask on the video layer and export with alpha. The RGB will be there, even though the mask hides it in AE.

Export uncompressed targa sequence

I work in a television station using Final Cut and LiveType to make graphics. Our clip server imports image sequences, but can only recognize uncompressed targa files. Exporting as a targa sequence from either program applies some sort of compression to the images. Currently we use GraphicConverter or Photoshop to do a batch convert to uncompress, but it would be handier to be able to export directly uncompressed. Is this possible? Alternatively, is there a 3rd party utility that can convert a DV movie to an uncompressed targa sequence. We have Cleaner, but it uses the same compression as Quicktime.
Thanks.

Thanks John. I get codecs and how they work (I've been making film and commercials for broadcast and cinema for over 10 years) what I find confusing is that apple have removed the choice to render / export with no codec at all - 'none'. We shot a film on Sony F3 with S-Log using an Aja Ki Pro to record directly to an external drive as ProRes 422, there's a weird problem with s-log and prores where the white highlights are clipped but the information is still in the file, because we recorded prores the only way to fix this problem is to apply 3way color correction in FCP (because prores is native to fcp) and bring the highlights down to 99IRE. We are adding CG set extension etc to a few shots so VFX dept are looking for 16bit tiff sequences so that there is no colour loss on their clips so everything will composite together properly in Nuke before online and grade. The only way to do this is to apply the colour correction in FCP, render as uncompressed 'none' then bring the uncompressed file into AE and export the tiff sequences. That way there is no loss of colour information or how the a codec will interpret colour. I've had to export with 'none' hundreds to times but with Lion that option has vanished. It's still there on Snow Leopard, which is what I have to use, but it's gone from Lion. Which is weird, no? Maybe Apple want to force us to use one of their codecs
