I have read through the forum and found a couple solutions for outputting with an alpha channel but it does not seem to work for me. I am trying to get a video file that I can use in Adobe Premiere with a transparent background. I have a photoshop file that I have saved as both a png file and a targa file. I can import just fine into crazy talk 6. When I output and bring into Premire, I get the file but it has a white background. Any suggestions? Thanks Ted

Hi Ted, Crazytalk can't output video with a transparent background. If you want your output with an alpha channel then you should choose Sequence Image format (PNG, TGA etc). Once you have outputted to this format you can then add these to your video editor to compile your movie. Hope this helps. :)

I'm trying tp export a png or targa sequence with transparent (alpha channel) background. How do I get rid of the white background? I am using CTAPro As long as you don't add a background to your scene then exporting to Sequence PNG will include a transparent background. For example add one of the comic characters, apply an animation and then export to sequence png. All the exported images will have a transparent background. If you are using your own custom character and that character has a white background around it then you will need to remove that first. You can find out how to do this HERE.

I'm still having issues with this process, using CTA Pro. I open the program, and import a previously masked PNG file of a head shot photo with alpha channel included. I then do the CT face fitting exercise successfully, and put the fitted face in stage mode. I anitmate the head. I never touch the background, although from the get-go the "stage" background is white. I simply want to export a sequence of the head being animated for use in After Effects. Exporting as a PNG sequence is leaving me with a white, NOT transparent, background. I tried puting in a green background to be keyed out in AE, but this doesn't work well with the image I'm working with. Please advise. Thanks.

The first thing to check is that your image has a transaprent background in CTA before export. You can do this very easily by adding a background into the preview window. If your character does have a transparent background you will be able to see this immediately. Once you are happy that your character has indeed got a transparent background you should be able to export to sequence image successfully (remove the background first obviously). If you find that your character does not have a transparent background in CTA then you will need to remove it first using the method I linked to in my previous post.

Well, as I indicated in my prior post I put a green background to see if I could key it out in AE. That confirmed for me in CTA that my image indeed has a transparent background. Is there a way to know whether the white background in the empty stage mode is a solid or transparent? For example, in Photoshop, transparent backgrounds can be represented by a grey and white checkerboard pattern.

Is there a plan to export to FLV with alpha channel at some point? This would be a really useful feature for integration into other Flash movies. Exporting to SWF would be great, too, if that also had a transparent background. Without this the process for doing what I'm trying to do is very cumbersome and makes the product hard to use.

Thanks for the feedback.

I found what is for me the easiest solution to export an animation to Premiere Pro First, I create a new project in Animator, I click on Settings and i create a colored background (blue or green, depending on the colors already in the picture, with further chroma keying in mind) Then i work on the project, up to final phase (video export) Then i import the project into Premiere Pro, I add a chroma keying effect to the clip, and I erase the background color. It's easy, it works fine

Peter, would you mind pointing me to some further instructions as to what to do in the video editor once you have published to the format you have suggested? I do need to be able to have my cartoons without background, ie. transparent like a PNG file. Thanks! :D John McConchie

The process will vary between different editors, but basically you would just load your sequence images into the video editor in the same way you would load a standard video. This is normally done using an Open or Import function to add them to the editor timeline. Then you can export to a video format of your choice.
