How to encode DNxHD 100i with ffmpeg?

[Selur]

I assumed:

ffmpeg -y -noautorotate -nostdin -threads 8 -ignore_editlist true -flags +ildct+ilme -top 0 -i "C:\Users\Selur\Desktop\input.mov" -map 0:0 -an -sn -vcodec dnxhd -profile:v 0 -b:v 100M -vf scale=1440:1080,zscale=rangein=tv:range=tv,setfield=bff -pix_fmt yuv422p -vsync 0  -sws_flags spline -mbd 2 -flags +ildct+ilme -top 0 "E:\Output\test.mov"

should work, but it returns:

Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

If I remove the '-flags +ildct+ilme -top 0' ffmpeg produces DNxHD 100 without a problem.

So what is wrong with my command line that ffmpeg complains about incorrect parameters?

Ps.: the file complete black test file I used: here, also created a thread about this over at videohelp, but since nobody could help I thought maybe at doom9s are more DNxHD users,...

[nevcairiel]

The hint is the "Profile selected is experimental" log message. It means it refused to use it due to the experimental status. You can add "-strict experimental" to the command to enable experimental features.
Of course often the experimental status is for a reason, so I would strongly recommend to verify the output afterwards.

[Selur]

@nevairiel: sadly adding '-strict experimental' didn't help.

ffmpeg -y -strict experimental -noautorotate -nostdin -threads 8 -ignore_editlist true -i "C:\Users\Selur\Desktop\input.mov" -map 0:0 -an -sn -b:v 100M -vf scale=1440:1080,zscale=rangein=tv:range=tv,setfield=bff -pix_fmt yuv422p -vsync 0  -sws_flags spline -mbd 2 -flags +ildct+ilme -top 0 -vcodec dnxhd -profile:v 0 "E:\Output\test.mov"

didn't either. but it seems like the bit depth conversion is the issue

[FranceBB]

What are you guys doing up at 5AM on a Sunday?! O_O
Anyway, we do encode in DNx with ffmpeg using FFAStrans and the files are accepted by AVID Media Composer, AVID Media Director and AVID Interplay Access.
Give me a bit / few minutes to get up, shower, have breakfast and get to work and I'll give you the right command line.

[Selur]

No hurry and thanks for looking into it.

[Jamaika]

Hi Selur
What did the developers improve in ffmpeg? "Constify frame->data pointers for encoders where possible"
https://github.com/FFmpeg/FFmpeg/com...dec/dnxhdenc.c
I'm a lousy advisor. How does codec work with thread 1?

[Selur]

Sadly using '-thread 1' instead of '-threads 8' doesn't change a thing.

[FranceBB]

Ok, so, sorry for the late reply, but it is Sunday after all ehehehehe
So, for the DNxHD standard, you have different version according with the different framerates, so basically it changes if you're encoding in 25i or 30i (or indeed if you're encoding their progressive counterparts).
Also please note that there's a difference between DNxHD and the "new" DNxHR and today I'm only gonna talk about the "old" DNxHD.

Let's crack on, shall we...

Currently you have the following possibilities in terms of resolution and framerate in DNxHD:



- 1920x1080 60p
- 1920x1080 59,940p
- 1920x1080 50p
- 1920x1080 30i
- 1920x1080 29,970p
- 1920x1080 25i
- 1920x1080 25p
- 1920x1080 24p
- 1920x1080 23,976p
- 1280x720 59,940p
- 1280x720 50p
- 1280x720 29,970p
- 1280x720 25p
- 1280x720 23,976p

According to each of these profiles, there are different specs and indeed different bitrates.
Since you're interested in the interlaced modes only and I'm gonna talk about 1920x1080 30i and 1920x1080 25i only.
If you go for 1920x1080 30i, you can have DNxHD 220x or 220 (the one with the "x" is 10bit, while the one without is 8bit) or DNxHD 145 which is 8bit only.
If you go for 1920x1080 25i, you can have DNxHD 185x or 185 (the one with the "x" is 10bit, while the one without is 8bit) or DNxHD 120 which is 8bit only.


From your post, you're targeting the "100" version in PAL which "doesn't exist" as it's DNxHD 120 8bit.
You see, I don't know if you're familiar with things like AVC Intra Classes in H.264, but essentially it's the same in DNxHD.
In H.264, when we talk about "Intra Class 100", we don't mean 100 Mbit/s for ANY given framerate, in fact Intra Class 100 in H.264 gives you 112 Mbit/s for 25i, 223 Mbit/s for 25p etc.
So... in DNxHD, the 100 class is:

- 290 Mbit/s for 1920x1080 60p and 59,940p
- 240 Mbit/s for 1920x1080 50p
- 145 Mbit/s for 1920x1080 29,970p and 30i
- 120 Mbit/s for 1920x1080 25p and 25i
- 115 Mbit/s for 1920x1080 24p and 23,976p

so the one you're interested in is 120 Mbit/s 25i, in your case.
As to the audio, the standard dictates either discrete PCM mono channels 24bit 48'000Hz or PCM Stereo channels 24bit 48'000Hz OR if you have like 5.1 you must use DolbyE while for 5.1.4 Atmos you must use DolbyED2 and aside for PCM, none of them can be encoded with free open source software 'cause they're proprietary codecs that belong to Dolby.
Anyway, even for 5.1 etc, most studios will accept them as discrete Mono PCM channels (1ch per track), so it won't be a big deal.
Last but not least, if you're gonna go for .mxf, DO NOT use the FFMpeg mxf muxer as it's really bad and full of flaws, so it's much much better to mux (or remux) using BBC BMX Transwrap, which is free and open source too! (but most importantly it's proven to be working with AVID appliances).


The command line would then be:

AVS Script:

ColorBars(1920, 1080, pixel_type="YV16")

ChangeFPS(25)

Trim(0, 1500)

BAT File:

ffmpeg.exe -i "AVS Script.avs" -vf "sidedata=delete,metadata=delete,setfield=tff,setdar=16:9,setsar=1" -timecode 10:00:00:00 -tag:v AVdn -profile:v dnxhd -c:v dnxhd -strict -1 -b:v 120000000 -r 25 -pix_fmt yuv422p -aspect 16:9 -field_order tt -top 1 -flags +ilme+ildct -color_primaries bt709 -color_trc bt709 -colorspace bt709 -color_range tv -chroma_sample_location topleft -signal_standard 4 -c:a pcm_s24le -ar 48000 -af loudnorm=I=-24:LRA=12:tp=-2 -f mxf -max_muxing_queue_size 700 -map_metadata -1 -metadata "creation_time=now" -y "pre-final_output.mxf"

bmxtranswrap.exe -p -y 10:00:00:00 -t op1a -o "final_output.mxf" "pre-final_output.mxf"

pause

And the resulting file is gonna be:






Of course if you have to create really interlaced contents, make sure to go to 50p and divide in fields like this:

ConvertFPS(50)
assumeTFF()
separatefields()
selectevery(4,0,3)
weave()

as you would for any PAL stuff.

This is a folder with everything in it: https://we.tl/t-lp4Q4NRrmZ

[Selur]

wetranfer link gives me: "Yikes, that page can’t be found."

I was aiming for

[dnxhd @ 00000182e21c0e00] Frame size: 1440x1080i; bitrate: 100Mbps; pixel format: yuv422p

which is listed by ffmpeg and is also listed over at https://en.wikipedia.org/wiki/List_o...HD_resolutions

I only encode to .mov not .mxf.

Also I want to use ffmpeg only not Avisynth.

-> can't get this to work here at all.

Funny thing is, if remove the "-flags +ildct+ilme -top 0" from:

ffmpeg -y -strict experimental -noautorotate -nostdin -threads 8 -ignore_editlist true -i "C:\Users\Selur\Desktop\input.mov" -map 0:0 -an -sn -b:v 100M -vf scale=1440:1080,zscale=rangein=tv:range=tv,setfield=bff,scale,format=yuv422p -pix_fmt yuv422p -vsync 0  -sws_flags spline -mbd 2 -flags +ildct+ilme -top 0 -vcodec dnxhd -profile:v 0 "E:\Output\test.mov"

and thus call:

ffmpeg -y -strict experimental -noautorotate -nostdin -threads 8 -ignore_editlist true -i "C:\Users\Selur\Desktop\input.mov" -map 0:0 -an -sn -b:v 100M -vf scale=1440:1080,zscale=rangein=tv:range=tv,setfield=bff,scale,format=yuv422p -pix_fmt yuv422p -vsync 0  -sws_flags spline -mbd 2 -vcodec dnxhd -profile:v 0 "E:\Output\test.mov"

thus aiming for:

-> problem is that I want the

[dnxhd @ 00000182e21c0e00] Frame size: 1440x1080i; bitrate: 100Mbps; pixel format: yuv422p

but I can't get ffmpeg to encode to that.

ffmpeg -y -noautorotate -nostdin -threads 8 -ignore_editlist true -i "C:\Users\Selur\Desktop\input.mov" -pix_fmt yuv422p -map 0:0 -an -sn -vf format=yuv422p,scale=1440:1080,zscale=rangein=tv:range=tv,setfield=bff,colormatrix=bt601:bt709 -vsync 0  -sws_flags spline -vcodec dnxhd -profile:v 0 -b:v 120M -mbd 2 -flags +ildct+ilme -top 0 "E:\Output\test.mov"

does work, but create DNxHD 145,... so from my point of view something does not work as it should -> https://trac.ffmpeg.org/ticket/9865

You need to put it after the input file (eg. after the -i <xx>), so that it applies to the output encoder, instead of the input.
All options before the input file pertain to the input, all options after the input file pertain to the output. If you use multiple inputs, then the same rule follows on a per-file basis.

As long as your output log contains this line, you did not properly enable experimental mode:
[dnxhd @ 000001f07f321b80] Profile selected is experimental

@nevcairiel: Thanks! You were right! adding '-stric -2' does help somewhat, but using

ffmpeg -y -noautorotate -nostdin -threads 8 -ignore_editlist true -i "C:\Users\Selur\Desktop\input.mov" -strict -2 -pix_fmt yuv422p -map 0:0 -an -sn -vf format=yuv422p,scale=1440:1080,zscale=rangein=tv:range=tv,colormatrix=bt601:bt709,scale,format=yuv422p -vsync 0  -sws_flags spline -vcodec dnxhd -profile:v 0 -b:v 100M -mbd 2 -flags +ildct+ilme -top 0 "E:\Output\test.mov"

the output is DNxHD 220i :/

-> something is still wrong with the call.
