@Vanyok — Just use the official encoding profiles for MeGUI. Get them here: https://longplays.

Hi! Sorry, if my question will a little stupid. Can I use MP3 codec for audio compressing? I tried asked admins in IRC chat, but I didn't recieve an answer. Thanks in advance for response!

On the YT channel (in About section), you'll find a Discord join link. Much better than using the IRC, plus that you can check back without needing to log in every time.

KAGE-008 How do I Submit and Upload my longplay?

I remember watching that when I was 11 (I'm 24 now). It was so great lol.

I'm curious, Do you watch Happy Tree Friends?

Yes, it is.

Is it okay If I upload my Kid Chameleon? KAGE-008?

You don't need to ask for a permission. Everyone is free to record anything and submit them. Remember to use the tools we use for encoding.

Can you just be flexible and let me upload my Kid Chameleon longplay? KAGE-008
