Hi anyone,
I would like transcode from .mxf to .mjpg with FFMPEG but my NLE (In Sync Speed Razor 5.51) don't read the output files that I generate with ffmpeg.
I have upload my input files C0020.MXF on my dropbox: you can download it if you go on www.dropbox.com ad logon into it with this credential:
user: mrocchini@email.it
pass: centrale
My source is C0020.MXF and my reference output il C0020.AVI
I can not directly import .mxf files in Speed Razor, but I can use .avi/mjpg file e.g. the C0020.AVI I have in the dropbox.
This C0020.MXF is generated exporting C0020.mxf from another NLE (In Sync Blade 2.2) but the same results I can achieve using Virtualdub (I have previously installed the PIC Mjpeg compressor/decompressor in my pc).
I prefer use FFMPEG because I need of a -vtag MJPG [virtualdub generate as video tag "mjpg" but Speed Razor can use only "MJPG" and not "mjpg", but when I modify the output file .avi of virtualdub "mjpg"--->"MJPG" with a HEX editor the file is correctly readable by Speed Razor, so I can prefer use ffmpeg. There is another reason for using ffmpeg: ffmpeg export the same timecode to the .mjpg/avi file of the souce, Virtualdub loss the timecode metadata tag]
For trascoding C0020.mxf I use:
ffmpeg -y -i c0020.mxf -vcodec mjpeg -pix_fmt yuvj422p -vtag MJPG -an output.avi
but output.avi don't work, the NLE import the file but don't play it.
I would like to achieve a c0020.avi with ffmpeg that have same caratherics of the one I have in the dropbox, this is ok, I can play this file on the NLE:

It seems to me the only difference from c0020.avi (the ok file) and ouput.avi (the wrong) is c0020.avi is "progressive".
Can I achieve the progressive with FFMPEG? thank to all

I was able to open the video in VirtualDub after a straight remux with ffmpeg:
Code:ffmpeg -i c0020.mxf -vcodec copy -acodec copy c0020.avi

My NLE can manage only Mjpeg files. Remux.avi is a mpeg2 and Speed Razor can not manage directly mpeg2 video files: it can do it teorically but the playback is jerky because using VFW codec.
Speed Razor support native Mjpeg and my target is only Mjpeg.
My source = .mxf files [mpeg2 hd 4:2:2] ; my target Mjpeg al least 50 Mbs 4:2:2
using zeranoe version of ffmpeg seems possible achieve directly mpeg2 files:
ffmpeg -i c0020.mxf -vcodec mpeg2video -an output.avi
(in low bitrate mode)
But I need Mjpeg -

Have you tried encoding with ffmpeg with 4:2:0 chroma instead of 4:2:2? Does your editor accept that?

Is not possibile because it does not support natively Mpeg2. It have a plugin (mjpeg_avi.rzf) that can manage directly only mjpeg format... it's an old but powerful NLE. Unfortunately the software-house (In Sync) manufacturer has closed just before release hd-version.
It have a brother: Blade 2.2 that can import also .mxf and mpeg2 but the external call to vfw files causes many problem of jerky playback and other problems.
Speed Razor 5.51 and Blade 2.2 can only manage directly mjpeg .avi files: I have do a series of test with .mjpeg using matrox .mjpeg and PIC .mjpeg video codec: at the best results the quality is 99,9% the original files.
If I transcode a .mxf avi source with the PIC mjpeg I achieve in mjpeg practically the same quality even if the disk size is 200% greater the source.
By many and many tests I conducted with broadcast monitor I can say that the loss of quality is absolutely not visible to the naked eye: using PIC mjpeg if the quality ratio is 19 the quality of transcoded video is 99,9% the same.
I can tell you that in this case the loss of quality is absolutely non-existent.
If you do not believe try to use the pic exactly as I have configured and compares the source and destination in a HD broadcast monitor: without knowing during the switching you will not be able to distinguish the origin and destination.
My problem is this: transcoding in .mjpeg I used blade or virtualdub but for practicity I need to use a command line system.
My question is: I need use FFMPEG to achieve the same results (c0020.avi) of virtualdub. When I open a file generated with virtualdub is all ok, but my nle don't open files mjpeg generated in FFMPEG, maybe because it don't do the progressive -
my problem is encoding with a "MJPG" tag: ffmpeg do it, virtualdub not (virtualdub write mjpg and not MJPG)
my problem is in encoding, not in decoding
My NLE (speed razor 5.51) have and internal decoder, and can manage mjpeg file by a specific plugin (mjpeg_avi.rzf) so this allow to decode and internally-manage directly the video files, this allow to avoid the use of VFW-codecs and and all the problems that this implies. Unfortunately it can manage only mjpeg files.Last edited by marcorocchini; 25th Sep 2013 at 13:53.

tHE source file is on my dropbox [C0020.mxf]
here I upload the first 30frames reencoding in Matrox Mjpeg @ 10 MB/s (if you need matrox mjpeg codec please go in my dropbox, I have upload the codec in pub folder)
I have used Virtualdub to encode, and the Mainconcept .mxf reader to load the C0020.mxf in virtualdub
I found the 2 videos are indistinguishable -
yes it's strange, seems the ffmpeg don't do a type of file clearly interalced or progressive: virtualdub produce mjpeg file clearly interlace (in mediainfo) and blade produce mjpeg file clearly progressive (in mediainfo) and both are playable in the nle speed razor.
Using FFMPEG, mediainfo don't specify interlaced or progressive... and the speed razor can not read nothing of the ffmpeg output -
excluding the problem on video, using ffmpeg I have 2 important advantages:
1) the file output have the correct header ("MJPG" and not "mjpg")
2) I can trasfer timecode in the ouput
... but the video part are not readable from the NLE
Using Virtualdub, the video part is readable... but the header is not correct (I have to use an Hex editor and manually set "MJPG" in place of "mjpg") and I loose timecode
It's very strange because ffmpeg is a good tool
... ... Is there a way to use VFW codec by ffmpeg? -
Have you tried remuxing the output from ffmpeg with VirtualDub (Direct Stream Copy mode)? At least as a test. To see if it's something about the way the file is muxed. VirtualDub includes an ODML header and arranges the chunks differently.
Or what about using -pix_fmt yuyv422 in ffmpeg? -
I have try this:
ffmpeg -y -i c0020.mxf -vcodec mjpeg -pix_fmt yuvj422p -b:v 50M -an -vtag MJPG testout.avi
Next passage:
load the testout.avi (in my system the default mjpeg codec is "pic mjpeg codec v.4"), set No audio, direct stream copy and savi to avi testout2.avi
import testout2.avi in Speed Razor: not readable
Header of testout2.avi seems ok but file not readable -
Very-Good question --- ffmpeg can't use VfW, BUT Mencoder can:
http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-video-for-windows.html
NOTICE: Don't take that table of "supported codecs" too seriously, up-to-date documentation has never been the strong point of the Mplayer project

The "-b:v 50M" helps the image quality a lot.
Did VirtualDub display the video properly? What decoder did it use? You can use File -> File Information -> Decompressor to see what decoder was used.
Did you try using -pix_fmt yuyv422 in the ffmpeg command. I'm thinking whatever decoder you're using doesnt like planar 422. -
MediaInfo thinks it works

-
The "p" in "-pix_fmt yuvj422p" stands for planar, not progressive. Ie, the video is stored as YYYYYYYY... UUUU... VVVV..., not YUYVYUYVYUYVYUYV...
Since each scan line of YUV 4:2:2 video has its own chroma the video is progressive if the 4:2:2 source was progressive, interlaced if the 4:2:2 source was interlaced, regardless of what's flagged at the container level. -
^ Well-spotted, jagabo
So I had to give a try to yuv2lav (from the MJPEGtools package),
and probably it'll be as good ( or bad ^.^;; ) as Mencoder for the OP

I tried to change strategy: in the project setting of the Speed Razor ha have set the using of external-codec call.
So this way the Speed Razor use PIC mjpeg codec for render parts, transitions ecc.. but I can not set the Speed Razor for use a Mpeg2 codec because playback is wrong, I can use only mjpeg files.
Using:
ffmbc -y -i c0020.mxf -vcodec mjpeg -pix_fmt yuvj422p -vf colormatrix=bt709:bt601 -sameq -vtag MJPG -an testout.avi
it all ok, Speed Razor import clip and work properly when the Speed Razor use the PIC mjpeg external codec.
Using:
ffmpeg -y -i c0020.mxf -vcodec mjpeg -pix_fmt yuv422p -vf colormatrix=bt709:bt601 -q:v 0 -vtag MJPG -an testout4.avi
don't import correctly.
And yet the two compilers semms are virtually identical but using ffmbc testout.avi is playable, with FFMPEG no.
So your question is: why you don't use FFMBC? because FFMBC don't copy the timecode metadata tag.
