Some question about FFMPEG

[kucing]

hi, this is my first post, sorry if my English is bad, I am not a native English speaker,
and I have some questions about FFmpeg:

1. does FFmpeg support h266/VCC encoder? if yes how to use it, if not, any info on when they probably release it?

2. is there any way to copy the current time in FFplay (it is called timestamp right?) or export it to a TXT file?

3. how to add audio in the middle video, let say I have a 1-minute video, I like to add 'C:\Windows\Media\tada.wav' in the second of 30, how do I do this?

4. I don't know how I must explain this, I like to combine this:

with this:

so the result is similar to this:

(I know the images don't match, but you get it right?)
can FFmpeg do it?

5. how to add a subtitle to the video but make it "unextractable"? or make it like a watermark?

6. I like to make screenshots images from a video every some second, but the output images format is monochrome BMP, how to do this?

thanks for reading

my 2cents,..

1. does FFmpeg support h266/VCC encoder? if yes how to use it, if not, any info on when they probably release it?

No. No there's no eta about vcc supoprt in ffmpeg.

2. is there any way to copy the current time in FFplay (it is called timestamp right?) or export it to a TXT file?

I don't think there is.

how to add audio in the middle video, let say I have a 1-minute video, I like to add 'C:\Windows\Media\tada.wav' in the second of 30, how do I do this?

You either manually 30seconds of silence to the file using some audio editor. Or you create a filter chain that does it for you, see https://superuser.com/questions/579008/add-1-second-of-silence-to-audio-through-ffmpeg

4. I don't know how I must explain this, I like to combine this:

might be possible with chromakey + overlay , see: https://stackoverflow.com/questions/8299252/ffmpeg-chroma-key-greenscreen-filter-for-images-video

5. how to add a subtitle to the video but make it "unextractable"? or make it like a watermark?

6. I like to make screenshots images from a video every some second, but the output images format is monochrome BMP, how to do this?

I don't get the question, ...

thanks alot Selur for replying
1. clear
2. clear
3. I think I must edit them using video/editor if the case like this
4. I bookmark I need to study it
5. clear
6. if you open an image using ms-paint, you can save it as monochrome BMP, maybe the better question is how to produce images "monochrome grayscale"

anyway thanks again for the reply, I really appreciate it
