ffmpeg in 720p

Question

fmpeg

There are a lot of videos from fotik in fullhd, all this weighs indecently a lot.
I would like to overtake ffmpeg'om in 720p.

No matter how much the settings are tormented, the quality loss is still quite noticeable, primarily in terms of sharpness.
ffmpeg -i p_%%F -vcodec libx264 -b 2000k -bt 2500k -ab 256k -ar 44100 -ac 2 -vol 256 -skip_frame none -coder 1 -async 1 -flags +loop+mv4 -me_method tesa -nr 0 -wpredp 2 -g 250 -qcomp 0.60 -qmin 10 -qmax 51 -bf 16 -sc_threshold 40 -qdiff 4 -keyint_min 25 -deblockalpha 0 -deblockbeta 0 -b_strategy 2 -cmp chroma -me_range 16 -flags2 +wpred+dct8x8+mixed_refs+mbtree -trellis 1 -partitions +parti8x8+parti4x4+partp8x8+partb8x8 -i_qfactor 1.41 -psnr -y %%~nF.mp4

Can anyone share their settings?

Do not offer other software :)

Answer 1

Have you tried the -sameq switch?

Answer 2

I don’t see something in this line, where is the actual scaling to 720: -s 1280x720

Answer 3

Since libx264, so why not use x264 itself, is it easier and clearer there?
x264 --crf 18 --preset veryslow --tune film --resize:width=1280,height=720,method=lanczos --output output.mp4 input.mkv

Answer 4

A friend helped me to make m2ts 1080i 50 > 720p with watermark overlay + screenshot creation from the second second. As a result, from a 327 megabyte file, an mp4 with a size of 23 megabytes was obtained. The quality of the stream was set to 2850 kilobits.
Everything is done with one run of the bat file. Since I need it for work (a lot of video files), the bundle works in batch mode. Once you run the file and forget, everything is converted for you, watermarked, a screenshot is taken. Plus, we increased the conversion performance due to multi-treating. Patched AviSynth. Here is an example of the output. Watch in 720p.
