FFMPEG: how to encode in target size mode?

[marcorocchini]

Hi,

in this days I have try a new NLE called ***** ***** that I have use to export videos of my cats, one video have duration of 1 hour and 15 minutes and it is 468GB (the video part) because is and uncompressed HD

I have cats.avi and cats.wav

cats.avi is a YUY2 uncompressed video, interlaced, BT.709
cats.wav is a 48Khz L+R stereo audio file

Now I would like do with ffmpeg two types of encoding:

- one in MP4 using the best compression (crf?), in progressive mode, keeping HD 1920x1080, keeping bt.709, at a target size of 9 GB and keeping the 4:2:2 colorspace

and

-one in mpg SD suitable for DVD (4:2:0?), interlaced, scaling the original HD master (cats.avi) from HD to SD and convert into BT.601 at a target size of 4,7 GB

Kindly I wonder: what is the commandlines to do this?

thanks

mux those video and audio streams together, then use this Dmfs Avi to mp4.zip , you have one batch file there, so you drop one ini file and that avi onto that batch or simply call that batch, one pass only so far, so find your CRF before:
_AVI_to_MP4.BAT "some.INI" "your.avi"
where you just grab suitable INI in that folder and tweak it to what you need (with your Avisynth script etc), give it a new name, like my_new.INI and use it in that above command line

for DVD you use this dmfs from Vegas.zip where you drop that muxed avi into "DVD from HD interlaced.BAT", command line could be:
"DVD from HD interlaced.BAT" "your.avi"

do not ask about how to modify those batch scripts, if needed, I think you can do it yourself now
