Every time I try to export my animation with a transparent background, I get some kind of "saw teeth

missnamis

hello!

I hope you can help me with this topic!

Every time I try to export my animation with a transparent background, I get some kind of "saw teeth" in some areas of the clip.

I do not understand it, because the layers are perfectly cut and without background.

Any idea what can happen?

Thank you!

Hello again. The problem persists.
When I check the "Show canvas" option, a background with squares appears.

All the best.

Hello, I have already attached the files.

Let me know what the problem is please.

I have exported the animation in several ways, but they all give the same result, strange bits keep appearing on the character.

Thank you for sending us the model files and other information.
The squares that appear in the exported video are patterns that represent transparency.
Please try to set the background color so the squares will not appear.

Best regards.

missnamis

I have sent you several mp4 video formats with a "transparent" background because that is how I need it.

I don't need the video with a colored background, but TRANSPARENT.

Why does a look wrong when exported without a background?

Exactly the same thing happens in your official files.

Thank you for your reply.
As shown in the manual previously provided, this is the output due to the specifications.
The way to avoid this phenomenon is to export Still image (sequential number) and then make them into a movie using different software.
We apologize for the inconvenience and thank you for your cooperation.

Best regards.

I don't understand what i have to do to solve this. Why my transparent mp4 looks bad?

@missnamis
There is nothing wrong with the file you created.
We have looked at the file you sent us and confirmed that it is exported according to the specifications of the Cubism Editor.
The specifications are as described in the manual.

Cubism's video export is a straight output of an image with alpha due to its specifications.
For this reason, when a file exported in H264 is played back in a media player, the translucent representation may not be displayed correctly.
If you want to create a video that can correctly display translucent expressions in H264, check the [Show Canvas] checkbox at the bottom of the [Video Output Settings] dialog box and export the video.

When the canvas is displayed, the background is not transparent.
The way to avoid this phenomenon is to export Still image (sequential number) and then make them into a movie using different software.

That is all for your information. I will refrain from further replies. Thank you very much.

what type of software?
