Dear friends of CLIC:

I'm happy to announce that the CLIC 2025 website is now online. Please check https://compression.cc for information on how to participate!

We will still be adding a few more details as we approach the start of the validation phase next month. Let us know if you have any questions or concerns at this point.

All the best –
Jona, on behalf of the CLIC committee.

Hi Jona, 

Thank you for the exciting news! 

Is it possible to know the range of the target bitrates that the video compression tracks will use? 
For example on the Image Compression track there are bpps listed, is there a bitrate range that can be shared with us for the video compression track? For example 50-500kbps? 

- Darren R.

Hi Darren –

thanks for your question. This year, we decided to adapt the bit rates to each sequence to better account for vastly different content, and we are still finalizing our selection.

But currently, it looks like bit rates will end up in the range 40-400 kbps, averaging to about 200 kbps. I don't think that will change dramatically.

Best!
~ Jona
