Google AI and ffmpeg preset

[pchan]

Hi All,

I just want to share what I have been through with ffmpeg preset with the help of Google AI.
1. The format of the video source e.g. 1440x1080p(16:9) aka 1080p Anamorphic.
2. The intended video output format e.g. smartphone, iphone, smart TV etc.

It can even provide script for .bat file that produce the most compatible video.
"%FFMPEG_PATH%" -i "%INPUT_DIR_PATH%" -vf "scale=1920:1080" -c:v libx265 -crf 28 -preset slow -pix_fmt yuv420p -tag:v hvc1 -c:a aac -b:a 192k -ar 48000 "%OUTPUT_DIR_PATH%"

It's indeed a new frontier.

Just read the docs:
https://www.ffmpeg.org/documentation.html

That all AI has done, its learning machine.

1440x1080p isn't 16:9

It will be covered in the docs somewhere otherwise AI couldn't have given the answer. AI isn't magic it learns thru reading information and regurgitating it.

1440x1080p isn't 16:9

It is the blu-ray standard anamorphic DAR=16:9 SAR (aka PAR)=4:3 format. Seldom used though for commercial releases, but it is legal and blu-ray compliant.

Exactly like @Sharc wrote - this is common HD anamorphic 16:9 - for example HDV ( https://en.wikipedia.org/wiki/HDV?useskin=vector ) camcorders use this - it was also quite popular in ATSC broadcast - reducing luminance resolution allows to keep acceptable quality with MPEG-2 encoding.

@Thread... after all i would expect from AI more... this is example of quite primitive script - disappointing...

Thank goodness, for a moment I thought I was wrong.

I was in a situation that being "forced" into ffmpeg. A user who is in his 70s and he is only familiar with this old video editor that cannot output HEVC format. Now, it's iphone and google drive and not DVD discs. So, Avisynth+, Advanced FrameServer and Google AI. As you may have seen my other thread on 64-bit Avisynth setup issue. No time to dive in the ffmpeg document and all I need is to get it to work. Most importantly, automate the process into a few clicks with .bat batch file.

Of course, KdenLine would do a better job. But it cannot import old timelines. Hard to teach old dogs new tricks.

For me.. AI is the FINAL CRAP.

Learn something for real, return to the basics.

You don't need that AI ******* CRAP (and often flawed) excerpt to understand how a basic thing like this works.

Learn something. Use you brain. Be free.

When in the shorter runway, whatever works. For those who use Excel VBA and perl script, it comes handy. In an unfamiliar territory, it can open up avenue and help us learn faster. It's your choice.

I'll stick to reading the docs - just as AI does - but my syntax, after study, will be accurate, whereas AI's may or may not be.

We - as thinking human beings - are (and always will be) able to learn: AI will only be able to copy/paste and put some shit here and there..

If you ever need to create an English subtitle for a foreign language, you need have to a translator and sit through the whole film. It can do it and put it into the format that you need. No manual or documentation can do it. One can sure get there without it, but it's going to take time.

Just think of AI as just better search engine. As human, we should be able to ascertain the results. As for transcribing, do it on two languages one knows and judge for yourself. Granted that one do it manually, but it going to take time.

AI for me is pure crap, fake "helpers" based on algorithms possessed by greedy nasty corporations that want to manipulate your choices..

If i'll have to stay behind spending more time learning new things and improving.. it's normal for me.

AI teaches you nothing, never.. it's only a.. "magic" can full of crap.. that stole you something, in the end.

Be happy, it's your choice. Not mine.

You can always ask on this forum and i bet real people may provide better examples. ffmpeg is simply versatile and self sufficient tool - that's why it is so popular - script can be reused multiple times.
I started with VirtualDub and Avisynth but at some point switched to ffmpeg.

The basic, the basic, the basic ???
Yes of course, no basic leads to to a new frontier ???
