• [x] My stickers do comply with all animated sticker requirements

Problem Description
I have downloaded the latest Android demo app version and I've changed the animated sticker pack with my stickers. I'm getting an Sticker file might be corrupted or invalid error when adding the animated sticker pack. The problem is with the last sticker (Winnie Pooh) because when I do not add it in the content.json, I can add the animated sticker pack with no problem. My question is why am I getting this error when my sticker complies with all requirements? winnie_pooh.zip

Thank you in advance.

Hi @imagetag6608 , I had looked your file, i was tried look into your gif file 1.gif, and when i delete 1 frame with 13 ms delay, i can add it to WhatsApp, maybe you should check another gif and try to delete frame with over 10 ms delay.

And here is the proof i can add it to WhatsApp

I wonder how can @imagetag6608 use an animated sticker that does not comply with one of the requirements:

Animated stickers must have frames with minimum duration of 8ms

[imagetag6608]

@the2hl yes i did not understand. i am new in animation things and I am using photoshop frame animation. can you please guide me how can I send 8ms between two frames or explain the thing rule. if yes then its big thank you.

And the rule is 8ms minimum between two frames, so @coroman image has 3ms delays for every frame. so how its work?

I know its all every basic question but I did not have proper knowledge so sorry for that.

Hi @imagetag6608. I'm also new in animation and I am using GIMP as image editor. In GIMP, you can set the frame duration between parenthesis: (XX ms) You can check this tutorial: https://www.linuxtopia.org/online_books/graphics_tools/gimp_advanced_guide/gimp_guide_node80_001.html According to the requirements (README.md), you should set at least a 8ms frame duration. I don't know why @imagetag6608 has been able to add your sticker having frames with 3ms duration.

I can't understand why pack is available after deleting a frame with over 10ms delay. Anyone or @coroman knows it? I could not find it from requirements.

@BattleShipPark Actually, i didn't know either. But @imagetag6608 says that his stickers is under 10 ms, and when i looked up and founded one with 13 ms delay, then after delete it, i can add the sticker to whatsapp.

@coroman Thanks. Additionally, that frame is not 13ms but 130ms because ezgif uses 1/100 second not 1/1000 second

@simonzhexu I believe there is a bug in WA. Some frames with different duration might make problem.
