This may be too simplistic an answer, but you should try "-top 1" after "
+ildct+ilme"
-top 1 sets output to top field first
-top 0 sets to bottom field first
-top -1 senses what the input is and adjusts for

May have many other issues, but at a minimum you should add " -movflags

700hz up to 3.5khz is probably a good range.
Avoid boosting below 400hz (muddy) and above 10Khz (zingy).
I guess I'm suggesting some sort of EQ before the volume increase. Not sure
how that is done in FFMPEG.

Put this on Redbubble to see what they would charge. $24 seems like a lot.
Probably cheaper through CustomInk:

Is there an MTS SD format? I though it was AVCHD and supported 720p and

haven't used Windows / Directshow for a few years, but back in the day I

HuffYUV is available for ffmpeg, but can't

the 16/9 DAR and they will play back correctly. (This
is highly over-simplified without doing the math).
This, of course does not address the framerates. Either the 25fps PAL or
the 29.97fps NTSC will need to be converted to the other.

I have also been trying to teach FFMPEG skills to video editors in my
