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.
File > Export > Movie To Image Sequence > Options > TGA.
Make sure to create a dedicated folder as the destination...

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.

Exporting SpeedGrade Project with Embedded Alpha Channel

Hello! I am currently writing with a problem I can't seem to find a solution for in SpeedGrade. My problem is that I imported footage with embedded alpha channel enabling me to chroma-key out a green screen. I would like to export this file now with the alpha channel still embeded to be delivered to Premiere. Is this possible?
Your help is greatly appreciated!
Philip

Thanks Fran,
I'm using uncopressed QT, animation.
I did the color correction on a grading track and I think that's what killed the alpha, because when I selected the track with the footage the alpha was being read properly. So what I did instead is I saved a .look file and imported it in After Effects, I rendered from there.
Can you have the grading track read the alpha from the original footage or if not can you copy the attributes from one track to another, as if I was moving all the grading from the grading track to the footage tiself instead of having to do it again from scratch?
Thanks again,
David.

Export H264 pass-through movie with embedded text track QuickTime Pro 7 Windows?

Using QuickTime Pro 7 for Windows, I add a text track with closed captions to my H264 .mp4 videos.
The text track works great until I try to export it. After I've added the text track, the text track is displayed as long as the track is selected to be active using the Movie Inspector track GUI.
My movies are encoded as H264 for cross-platform compatibility, and need to remain in this format. The only way to save them in QuickTimePro 7 for Windows is to Export Movie to MPEG-4. I select Pass-Through mode to retain the resolution and bandwidth parameters that I initially encoded the video with.
Unfortunately, after I export to MPEG-4, the caption track is lost. It disappears. When I open the newly exported MPEG-4 caption file, and select Movie Inspector, the caption track is missing. Inspector only shows video and audio tracks.
If QuickTime Pro 7 for Windows correctly exported my text track with the video and audio tracks, then users would be able to view the closed captions upon playback in QuickTime Player by selecting View--> Show Closed Captioning (Ctrl+Alt+T).
Anyone been able to export to MPEG-4 pass-through movie with embedded text track QuickTime Pro 7 Windows?
Thank you!

Exporting to QT on Keynote with embedded narration or audio files doesn't work

When I create a Keynote presentation, I often publish them for viewing after the presenttion. I have been making presentations for a long time and never had luck with Keynote using narration. When you edit a narration, it first "appears" to erase everything from the point you choose to edit forward.   However, when you finalize the presentation and export to QT as a movie (yes the edits sound fine when you are using keynote itself) EVERY PREVIOUSLY RECORDED TAKE on each slide will playback at the same time making the audio incomprehensible. I'm using a 2013 2.3 GHz quad core i7 with 16 GB DDR3 and the newest Keynote 6.01 2013.   Narration has NEVER worked properly on any previous version, and still doesn't.
I had some advice to try recording QT audio and adding to the slide. Now, when recording to Quicktime, it does embed it, but in recording the presentation, it either doubles up the audio giving a strange echo or does the same thing if you ever edit the presentation.
Keynote is simply a buggy inferior product for use in recording presentations as far as I am concerned, and I am very very disappointed in Apple for not figuring these issues out.   It's not a new product, and it's not as if most educators are not participating in on-line posting or sharing their work as movies for later viewing by students.
I'd appreciate hearing what others do to work around these issues before heading back to Powerpoint or having to make complex i Movies with slides as images and adding qt narration to the movies.   Keynote claims to do this... it just but I've never encountered an apple product with more bugs.

I had some advice to try recording QT audio and adding to the slide. Now, when recording to Quicktime, it does embed it, but in recording the presentation, it either doubles up the audio giving a strange echo or does the same thing if you ever edit the presentation.
The problem Keynote has is that the sound and image content are not locked together which causes out of sync errors. This is why many users choose video editing applications when using sound in the presentations, as they have both image and audio tracks to sync sound properly together.
Start a new presentation to remove the previous sound recording, Keynote is holding onto the other sound files.
Add the graphic items to each slide and one sound file to each slide for the voice over
1 - In Inspector > Transitions; use start transitions automatically and set each transitions delay to the duration of the individual sound file.
2 - In QT export, set Fixed Timing and delete the value in the duration box, QT will then use the custom timings for each individual slide.
This procedure does work exactly as needed, Iv used this for nearly 6 years using 4 different versions of Keynote.

How would I export a text graphic jpeg with an alpha background?

Hi,
I made a simple text title and am trying to export it as a still frame jpeg and I can't get the export to have a alpha background? Any suggestions?
(I am using this text title for a new website.)
(I just got photoshop elements and don't know how to use it.)
Thanks

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

Encoding with an Alpha Channel Using Quicktime Pro

I am pulling my hair out trying to encode a green screen video that will play on a website so the website shows through the transparent alpha channel. Problem is when I encode to .flv or .mp4 the alpha channel is never retained even when I check "encode alpha channel" in the .flv export setting window. I have downloaded a trial version of Sorenson Squeeze and even that couldn't retain the alpha channel.
The video I am using was exported out of Final Cut Pro 7 using Quicktime Conversion using the Animation Million of Colors PLUS codec and when I test that it does indeed have a transparent alpha channel so something is happening when Quicktime Pro is encoding it.
Can anyone recommend a way to export a .mp4 or .flv with the alpha channel?
Thanks in advance for any help you may be able to give.
Benjamin Jones

You can also export a RGB video (without alfa) with any codec, and a second pass with obly alpha - it depends if you need that as a final export (then use codec than can export alfa) or intermediate format (then you can use image sequence or 2 pass video).

No more alpha in exported QuickTime movie from Keynote '09

Hello
In Keynote '08, I create a slide with no background (None).
I add some text with some fancy text IN and OUT features.
I export using the Animation codec and the transparency option.
When I reimport the movie in another Keynote '08 file, it inherits the transparency of the imported file and thus everything is perfectly blended.
In Keynote '09 it is not possible anymore.
Even if I import an exported QuickTime movie from Motion with a transparent background, it is not possible to have a perfect blend, all layers are opaque.
Last but not the least, adding transparent files on top of each other in QuickTime player does not preserve transparency despite the fact that the Animation + transparency features are added in the files.
Thank you in advance.

Hey Gary - first off, thanks for your reply! I am currently forcing spotlight to re-index to see if that might help me out. After that I will try your suggestion and run a system software check.
I need a ProRes export as this is going to be combined with IMAG footage from a live presentation as well as additional video from an Arri Alexa. I want to preserve as much quality as possible so that there isn't a discrepancy in the final edit. Originally, I was rendering a small test to the desktop to gauge output quality of animations etc. I did go ahead and re-export a second time to an external drive, but it doesn't seem to matter as Keynote appears to initially render everything to the startup drive no matter what. The second export still ate about 15 gigs from my startup disk and I am unable to find any sort of temp files anywhere!
I am showing all files in Finder and searching around the ~/private/tmp folders to no avail. In the image below there appears to be a discrepancy in the size being reported by finder and the size I'm seeing listed in terminal...

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.

Problem with embedded captions in quicktime export

Hi,
I'm trying to add embedded closed captions to a video. I just installed the latest version of Premiere Pro yesterday on my Mac. Should be simple, but alas!
I have this 3 minute video file: https://www.dropbox.com/s/5t9s1kgpa8s3f76/Revver%20Introduction-1080p.mp4
To which I added this .scc caption file: https://www.dropbox.com/s/2ickt0al7v6ggb2/rev3.scc
Things look great in the Premiere preview pane: http://screencast.com/t/HFZLVj6OX
But when I export as a quicktime video with embedded captions, I get a garbage output: https://www.dropbox.com/s/j3bmcx9yk5uuhy0/Revver%20Introduction-1080p-CC.mov
The closed captions display way more rapidly than they do in the Premiere preview pane. I didn't mess with any of the export settings - here's what I selected to get the export: http://screencast.com/t/dgx8a4v5sl7
What's going on? Why is this not working?
Rory

Wow that's awesome. Thanks Kevin.
I downloaded your project, located the source files as being on my machine instead of yours, and tried it out. Unfortunately the export still had some issues, but looking at what you did helped me figure out how to start again from scratch and do it correctly.
I think I understand now - I had been creating a sequence by dragging the video onto the new item. So the sequence used the attributes of the video clip. I hadn't realized I could create a new sequence with different attributes, as described in this article http://helpx.adobe.com/en/premiere-pro/using/creating-changing-sequences.html
So I created a new sequence, made sure it had 29.97 fps and correct dimensions (1440 x 1080), dragged in the video and scc, and exported.
Seems like it worked!
Here's the final verions, with captions embedded. You'll need to download it to see the captions, since dropbox's player doesn't support caption playback:

Export recorded slideshow, with embedded quicktime, to quicktime...

...doesn't capture the video.
I'm trying to export a Keynote '09 presentation, with recorded audio. The presentation also contains embedded quicktime video (a screencast). However, the resulting exported quicktime does not run through the embedded video (the initial video still is shown throughout the whole narration of the screencast). I'm using the "recorded timing" playback.
While its exporting, the Keynote preview actually shows screencast playing fine.
The embedded video plays fine when I export without the recorded audio.
Any idea what might be happening here?

Well i just found this and tried it, it worked
1) Go to export to QT as usual.
2) Click the second drop down (Formats) and select 'Custom...'.
3) A new window will pop up, click the 'Settings...' button.
My 'Compression Type' drop down was set to 'H.264'....I was told to
4) Change the 'Compression Type' to 'MPEG-4 Video.
(I do not think it is related to the fix being suggested or just as a preference, I was told to slide the Compressor - Quality slider on the bottom left to 'Best')
5) Click the 'OK' button on the bottom left
That window will close.
6) Click the 'Next' button and continue with your export.
Not sure why this works but it did. But i still cant do it the normal way.

Keynote does not support exporting with embedded Quicktime Movies

I hope this helps a few of you out before you run into this problem.
Keynote does not support export to Quicktime with any slides that contain a quicktime movie.
Created a 27 page slide show with transitions, music, narrations and 6 Quicktime movies (Actually LiveType Text scrolls)
When I attempted to export it never finishes the export cutting it short after about 20 pages.
And the pages with the movies, don't start playing.
It exports fine as a quicktime movie without the movies inserted though.
Spoke with Apple Support and they confirmed that quicktime placed files within Keynote playback is only supported from the native Keynote Application.
I read somewhere on this board that it was an issue with Quicktime version 7.5, not so as I tried the same test on a mac with Quicktime 7.42 and it had the same issue.
So, beware.
LJS

Maybe I didn't understand well what you said but it is possible to export a Keynote file with embedded Quicktime movies to a quicktime movie. Actually, I'm doing it and I works. BUT, the issue I get is that I can't get my embedded videos to loop. Grrr...

Exporting Quicktime with alpha channel

Hi,
I'm currently editing a piece full of talking heads that will eventually be converted to flash to be used on a website. The heads were shot on DVCPRO 50 on green screen and keyed using advant edge. I am using DVCPRO 50 timelines. I need to export quicktime movies including the aplha channel so that the resulting flash movies (which are to be encoded by another company) appear without the background on the website. When I look at my files on the screen they appear over the checkerboard background. I exported using animation codec set to million of colors +. Just as a test to see if that would work I encoded a flash movie from the quicktime file using the new Flash 8 "encode alpha channel" option. When I viewed the file it was over a black background. As a further check I imported the quicktime movie I had made into a new sequence set to animation millions +. It also appeared over a black background. Did I lose my alpha channel somehow? When I view the format info on the quicktime file, it lists the alpha channel as being "straight", which I assume means that an alpha channel is present. Can anyone help me out?
G5 Quad PPC Mac OS X (10.4.6) 2 GB Ram, Aja Card

OK I changed the sequence settings to animation millions + (as they were previously set to DVCPRO 50). When I did this all of the files became unrendered, which was the desired effect. I exported a 5 second piece animation millions +. It had a black background in quicktime, but when I imported the quicktime movie into flash encoder my subject appeared over the white default flash background. We have a winner! Now my only problem lies in export times. It took nearly 8 minutes on my quad to export that 5 second clip, and I have 34 clips that are at least 30 seconds apiece. I think I'm best off setting uyp a batch export to run over the weekend. Thanks again for all the help guys! I would have never figured out that the files had to remain unrendered in order for this to work.
