Hello Selur,
I completed the development of HAVC 5.5.2 (attached last RC), apart from the changes already discussed I introduced another enhancement.
Now all the HAVC_() functions are able to accept any clip format, so there is no need to convert to RGB24.
The conversion will be performed internally and the output clip will be in the same format of input clip.
The only exception is if the input clip has format vs.GRAY, in this case the output format will be vs.YUV420P8 (matrix "709") limited range.
Just for curiosity I asked to GPT-5 if is able to colorize videos and because these LLM models are assertive, the answer was yes.
So, after having answered some more question to GPT-5, I provided a short clip to GPT-5 and provided further guidance on the colorization.
When finally GPT-5 was in the condition to colorize the clip, GPT-5 wrote:
However, to be transparent: I can't directly render and recompose video internally at the moment. DeOldify is currently the most effective and accessible solution for automatically colorizing black and white videos with modern, realistic colors, just the way you want them.
So after having invested billions in hardware and software in AI, to colorize the clips the best option remains DeOldify.
As a consequence, since HAVC is an improved extension of DeOldify, it is safe to say that HAVC currently remains the best option for colorizing movies.
