Comment on XDCAMHD422Encoding in ffmbc

Comment by phillclarke:

Can you confirm that the -vtag option is only valid for XDCAM HD422 in a
MOV container? And not valid for MXF output?

Obviously the interlaced tags are only valid for 1080i options, but is that
also limited to only MOV output and not MXF?

Comment by baptiste...@gmail.com:

Yes MXF do not use fourc. I should probably rename the -atag and -vtag to
-afourcc and -vfourcc

No interlaced options are valid for both obviously

Comment by louk...@gmail.com:

Could someone be so kind as to provide a recipe to encode what Final Cut
Pro calls "Sony XDCAM HD 1080p24 (35 Mb/s VBR)"? This is my preferred codec
for editing quick projects in Final Cut. It's super compact, takes very
little cpu power, and looks very good considering it's small size.

How can I add pulldown to my 24p element to encode as 1080i60 for xdcam?
Do I need to put an AVISynth script as the source and add it in there or is
there an all-ffmbc option?

Comment by ericjol...@gmail.com:

Are their any switches or parameters that affect quality when encoding to
XDCAM HD 422? I'm noticing a lot of blockiness and banding being
introduced that isn't present when I encode to MPEG2 in ffmpeg. However,
ffmbc creates a file that Final Cut recognizes as XDCAM; ffmpeg does not.
Source footage is AVC MTS files.

Yes, there are you can use 2 pass encoding to improve the encoding and use
-mbd rd

Comment by cjpla...@aol.com:

I've got the encoding to 8-channel Mono MOV going using AVISynth to insert
my pulldown. Every time I load the AVS into VDub, the video and audio is
complete at 1 hour long. When I encode it with FFMBC, I only get the first
few mins of the content. No frame length parameters are given. Thoughts?
Would a STDout application be better than feeding it directly into FFMBC?

I do have a m2v(in.m2v) file and two mono wav files (inL.wav, inR.wav)

Hi Baptiste,
Thanks for this excellent fork of ffmpeg.

I would like to do a XDcamHD422 with 5.1 audio (6 mono channels)
Is it possible to do that, I don't found documentation of
the "-map_audio_channel"

If it can help, my source file is an avisynth script with
atotal=MergeChannels(a1,a2,a3,a4,a5,a6)
Audiodub (video, atotal)

I really hope you can help me

Regards,

Christophe

It depends on what your source file is.

Mxf audio remap example above does not work.

Comment by russells...@gmail.com:

Using the .mxf example above, would it be possible to map the stereo
channels to 4 separate tracks(repeating the channels twice)? If so could
you show code?

[ff...@googlecode.com]

Comment by russells...@gmail.com:

Okay, so finally figured everything out, but resultant file will not import
into xdcam browser, which probably means it will not copy to xdcam disk.
This should be the next item on the list: make the .mxf files actually
compatible with xdcam disk technology.

Well if you specify "-an" which means no audio channels what doe you expect?

Because all the parameters need to be on one line, or you need to escape the end
of line:-

ffmbc -i MVI_2013.mov -s hd1080 -target xdcamhd422 -an MV2013.mxf \
-acodec pcm_s24le -ar 48000 -newaudio \

Hello Baptiste,

I just tried the ffmmbc to create an MXF file compatible with the XDCAM 422
format, but it does not seem to be working with the XDCAM Browser software
v2.1 from Sony. My intention is to create MXF files and later ingest them
into XDCAM media using the Browser, and the same procedure seems to be
working if I select the MXF files that were originally created by some
XDCAM VTR.
I was able to match all characteristics from the original XDCAM VTR clip
using ffmbc, but I guess there must be something inside the MXF structure
that prevents me from using this clip with the Media Brower.

[ff...@googlecode.com]

Comment by Shirley1...@gmail.com:

For native editing in FCP, I convert MXF to ProRes MOV. The problem is how
to preserve multiple audio tracks in raw XDCAM MXF file? Finally I got
Aunsoft TransMXF Pro for Mac. Well, it do pretty good job to preserve and
separate multiple tracks in MXF.

I have created some XDCAMHD files with ffmbc but could not copy it to the
clip directory of the PDW-U2 drive.Error 0x8007054F any idea ?
The Sony XDCAM Viewer PDZ-VX10 Version 2.3 plays it normally.

[Bouke (VideoToolShed)]

I've done this with succes to a PDW U1.
Trick was to create files in QT container, then use the XDcam transfer tool
to copy it to disk.
There is a command line tool for this that you can riip out of the package,
forgot what part, but i'll try to look it up if you can't find it yourself.

I have looked on the Sony Home-Page for that transer tool but only find a plug in for Mac.I have some other MXF-XDCAMHD Files created on other third party products (omneon,avid,digitalvision...) and  copying these files to the clip directory is possible.So I think it  must something  incompatible with FFmbc  to the Sony standard.

How merge 8 mono channels in 2 stereo pairs?

[Andrew Green]

This is what I've figured out so far, this example allows me to run conversion on a folder of .mpg (anything really but mine are MPEG-TS (1080i59.94) with 5.1+stereo AES3 audio (4 stereo streams)) and output an XDCAM422 1080i60 (59.94 interlaced) for use with Premiere Pro CC:

#!/bin/sh
for file in /home/video/input/*.mpg
do
 echo "Converting $file"
 ffmbc -threads 8 -i $file -target xdcamhd422 -tff -vtag xd5b $file.mxf -map_audio_channel 0:1:0:0:1:0 -map_audio_channel 0:1:1:0:2:0 -map_audio_channel 0:2:0:0:3:0 -map_audio_channel 0:2:1:0:4:0 -map_audio_channel 0:3:0:0:5:0 -map_audio_channel 0:3:1:0:6:0 -map_audio_channel 0:4:0:0:7:0 -map_audio_channel 0:4:1:0:8:0 -newaudio -newaudio -newaudio -newaudio -newaudio -newaudio  -newaudio
 echo "Done converting $file"
done
echo "Finished Converting input files!"


As for the map_audio_channel command:
-map_audio_channel 0:1:0:0:1:0 -map_audio_channel 0:1:1:0:2:0 -map_audio_channel 0:2:0:0:3:0 -map_audio_channel 0:2:1:0:4:0 -map_audio_channel 0:3:0:0:5:0 -map_audio_channel 0:3:1:0:6:0 -map_audio_channel 0:4:0:0:7:0 -map_audio_channel 0:4:1:0:8:0

Map Input File 0 -> Stream 1 -> Channel 0 into Output File 0 -> Stream 1 -> Channel 0 (XDCAM wants 8 mono audio streams in PCM)
Map Input File 0 -> Stream 1 -> Channel 1 into Output File 0 -> Stream 2 -> Channel 0
Map Input File 0 -> Stream 2 -> Channel 0 into Output File 0 -> Stream 3 -> Channel 0
Map Input File 0 -> Stream 2 -> Channel 1 into Output File 0 -> Stream 4 -> Channel 0
Map Input File 0 -> Stream 3 -> Channel 0 into Output File 0 -> Stream 5 -> Channel 0
Map Input File 0 -> Stream 3 -> Channel 1 into Output File 0 -> Stream 6 -> Channel 0
Map Input File 0 -> Stream 4 -> Channel 0 into Output File 0 -> Stream 7 -> Channel 0
Map Input File 0 -> Stream 4 -> Channel 1 into Output File 0 -> Stream 8 -> Channel 0

Input/Output files start at 0, Streams start at 1, Channels start at 0

You'll need a -newaudio flag for each map_audio_channel as you're starting with an MXF with no audio streams. This will also insert silence into the channel if there's no input audio.

If you want interlaced MXF then make sure you use the -tff, I don't believe the -vtag has any affect with MXF, it's only for MOV.

Hope this helps you/someone!

-Andrew

[Rens van der Zwan]

Yes you can. I've used below commandline on Avids Airspeed 5000 clips to create mono audio tracks and leave the video part as it is. The input format is xdcamhd422 and audio is in pairs

ffmbc -i <infile> -an -vcodec copy -timecode 00:00:00:00 -target xdcamhd422 <outfile>
-acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:1:0:0:1:0
-acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:1:1:0:2:0
-acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:2:0:0:3:0
-acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:2:1:0:4:0
-acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:3:0:0:5:0
-acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:3:1:0:6:0
-acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:4:0:0:7:0
-acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:4:1:0:8:0


-map_audio_channel infile:instream:inchannel:outfile:outstream:outchannel

If your transcoding from one file to another single file then the infile and outfile will be 0.
The first audio track is on stream 1 (assuming video is on stream 0) . The first audio channel is on channel 0 and the second one is on channel 1.

I'm having problem with re-wraping avchd422 MXF file into MOV container.
I've tried your example and got mov file BUT:

- it has only one mono audio channel when checked trough movie inspector,
but displays four audio channels on PPmeter. (that is not that important
for me)

- it seems that it resets timecode to zero (doesn't read correct timecode
from source - it's there, at least it shows up in premiere) - i can't check
that, but console output tells me that it's 00:00:00:00

- when opened in QT player it displays black video, and I can't open it in
any other program (Premiere, Nuke, ...)

- when opened in VLC I have normal picture :((

It seems to me that I just forgot some flag or something which VLC ignores
and other programs do not. Data is there, I just cant figure out what I'm
missing.

And As sidenote, exactly same thing is happening in ffmpeg
