how to force ffmpeg to encode mpeg2 interlaced ?

[hydra3333]

Hello.

I am having difficulty trying to get ffmpeg to encode mpeg2 interlaced and would appreciate advice on how to do it.

No matter what I try, ffmpeg always treats the avisynth input as progressive and refuses to encode mpeg2 interlaced.

I had thought this on the ffmpeg commandline would force it:
-flags +ilme+ildct -top 1 -alternate_scan 1

As a test, I tried a native interlaced source file (not avisynth) and it re-encoded as interlaced OK.

My source is an mp4 720p 30fps - trying to convert to DVD, interlaced 576i (interlaced for "motion smoothness").

Commandline and output:

"C:\SOFTWARE\AVISynth\AvisynthRepository\AVSPLUS370_x64\ffmpeg.exe"  -v verbose -f avisynth -top 1 -i "test_a.avs" -sws_flags lanczos+accurate_rnd+full_chroma_int+full_chroma_inp -vf "setdar=16/9" -f dvd -video_format pal -b:v 8999999 -target pal-dvd -flags +ilme+ildct -top 1 -alternate_scan 1 -g 15 -strict experimental -an -y "test_a.dvd.mpg"

I don't know what your source looks like but motion interpolation often doesn't work well.

The output of your AVS script is progressive, 25p. The output of your ffmpeg encoding is interlaced, 25i, but the frames are progressive. So you won't have smooth video. You've commented out the parts of the code that convert 30p to 50p and then interlace 50p to 25i.

Also, for the purposes of an alternative option and checking the work,
open the script directly in HCenc GUI

Thank you. OK. It's a funeral, fairly static. I am open to other methods of 720p30 -> 576i25 and would value your expertise in that.

open the script directly in HCenc GUI

OK.
I have HCEnc, however avisynth is not "installed" (no registry keys and nothing copied into system folders, ffmpeg works if in the same folder as avisynth.dll), however I have not been able to get HCEnc to work in the same way, hence use of ffmpeg.
Looks like I may have to install avisynth to use HCEnc I guess.

yes that is so. Use this one

Thank you. I just tried again before I saw your post.

Using AVISynth-Universal-Installer (edited to not install registry keys or copy files into system folders) https://forum.doom9.org/showthread.php?t=172124 item 9 (Avisynth+ x86) if I pop HCEnc into the same folder as that avisynth.dll and run the gui, it says "Warning, Avisynth not installed" ... HOWEVER, if I press on, by loading a .ini and an avs script, it all loads and works fine (saying "Avisynth.dll loaded. Avisynth successfully initialized.") after all providing that I find and use all x86 filters.

Note that I added more to the reply. If you don't fix your script you won't get smooth motion with HcEnc either.

Good enough if it works. The install and uninstall of regular Avisynth is clean, for future reference.

Ah, ok took another look at your post.

I don't know what your source looks like but motion interpolation often doesn't work well.

The output of your AVS script is progressive, 25p. The output of your ffmpeg encoding is interlaced, 25i, but the frames are progressive. So you won't have smooth video. You've commented out the parts of the code that convert 30p to 50p and then interlace 50p to 25i.

Yes I commented them out just to test, since the ffmpeg log for the Output kept saying yuv420p(progressive).

I changed the script back to look like

# input is 720p 30fps
video = DGSource("G:\DVD\Ted-Funeral\2021.06.23-Funeral-TedJackson-ready.dgi",deinterlace=0).killaudio()
video = video.trim(0,-100)
#
# make double-framerate PAL progressive 50p
video = JohnFPS(video, num=50, den=1, Sharp=1, rFilter=4, BlkSize=8, Search=3, dct=0, ml=200.0, Mask=2, Blend=False)
#
# resize down to PAL SD (progressive) for DVD
video = video.Spline36Resize(720,576)
#
# make interlaced PAL 576i
video = video.AssumeFrameBased().AssumeTFF().separatefields().selectevery(4,0,3).weave() # make TFF interlaced 25fps, i.e. TFF 576i, for motion smoothness (could have converted to 576p instead but more jerky)
video = video.AssumeTFF().AssumeFPS(25) # test just do assumes ... same result through, ffmpeg does not encode interlaced
#
video

with result "yuv420p(progressive)"

Good enough if it works. The install and uninstall of regular Avisynth is clean, for future reference.

OK, thanks. Having multiple versions of AviSynth (I usually use x64, or vapoursynth) available seemed easier with AVISynth-Universal-Installer, as I try not to used Admin priv or to install stuff where I can avoid it.

I wonder if I missed seeing an x64 version of HCEnc ?

I don't believe there is a 64 bit version of HCenc. One of the good things about Avisynth Plus, 32 and 64 bit environments enabled

I changed the script back to look like

# input is 720p 30fps
video = DGSource("G:\DVD\Ted-Funeral\2021.06.23-Funeral-TedJackson-ready.dgi",deinterlace=0).killaudio()
video = video.trim(0,-100)
#
# make double-framerate PAL progressive 50p
video = JohnFPS(video, num=50, den=1, Sharp=1, rFilter=4, BlkSize=8, Search=3, dct=0, ml=200.0, Mask=2, Blend=False)
#
# resize down to PAL SD (progressive) for DVD
video = video.Spline36Resize(720,576)
#
# make interlaced PAL 576i
video = video.AssumeFrameBased().AssumeTFF().separatefields().selectevery(4,0,3).weave() # make TFF interlaced 25fps, i.e. TFF 576i, for motion smoothness (could have converted to 576p instead but more jerky)
video = video.AssumeTFF().AssumeFPS(25) # test just do assumes ... same result through, ffmpeg does not encode interlaced
#
video

with result "yuv420p(progressive)"

ffmpeg always sees YUV 4:2:0 output from AviSynth as yuv420p. Just encode it as interlaced MPEG2 and you'll be fine.

[hydra3333]

OK, thank you.

That's the bit I'm stuck on, for me ffmpeg won't encode interlaced

Sample attached.

It's working fine for me with (essentially) your AVS script and ffmpeg command line.

#

#
# make double-framerate PAL progressive 50p

#

video = video.Spline36Resize(720,576)

#

#video = video.AssumeFrameBased().AssumeTFF().AssumeFPS(25) # test just do assumes ... yields same result through, ffmpeg does not encode interlaced

Here's your Extract.mp4 video with the same processing:

You are a saint

A CKI issue by the looks. You pointed it out before and I did not understand it.

ffmpeg reports "yuv420p(progressive)" below, which to me is misleading.

However, mediainfo etc do report it as Interlaced/TFF !

[jagabo]

There's no way for ffmpeg to know whether the YV12 output from AviSynth is progressive or interlaced.

[hydra3333]

That makes sense (now you have pointed it out).

I'm happy enough with the output from this process
