I also tried dvcpro codec:

this warning also exist in current ffmpeg git.

so after some googling around I found those answers:

it. Encoding run at 6 fps single-threaded (1.4Ghz), 16 fps at ondemand (up to

There was message on quicktime ML back in time when dvc pro hd decoding was 
added to ffmpeg:

[Libquicktime-devel] DVCPROHD
From: Burkhard Plaum <plaum at ip...> - 2008-08-30 12:20:59 
  
  Hi,

looks like ffmpeg gets DVCPROHD support these days.
I've added the relevant fourccs to cvs:

"dvhq", // DVCPRO HD 720p50
"dvhp", // DVCPRO HD 720p60
"dvh5", // DVCPRO HD 50i produced by FCP
"dvh6", // DVCPRO HD 60i produced by FCP
"dvh3", // DVCPRO HD 30p produced by FCP

This together with ffmpeg svn from today decodes at least
the one file I tried. More testing is yet to be done :)

also, compilation error for main branch with external 2.8 ffmpeg was (sorry I 
forgot to add it to my message before):

It seems to work with DV (input: dv in avi, output - quicktime/dv)
and with mjpeg (mjpeg/quicktime -> photo jpeg/quicktime)

(I looked at how fast rendering happened on slowed-down CPU, for ~8 sec. long DV 
cut down clip)

mjpeg file was encoded with ffmpeg 2.8.11:

ffmpeg -i /dev/shm/tmp/ud_04102010-small.mov -acodec copy -vcodec 
mjpeg /dev/shm/tmp/ud_04102010-small_mjpeg.mov

I also tried DNxHD, but there seems to be no such  codec at CinelerraCV's 
encoding side. Test file was encoded with this ffmpeg command:

 ffmpeg -i ~/New_hdd/new_my_videos_magic_eye_cam/20150811_180635.MOV -vcodec 
dnxhd -b:v 90M -s 1920x1080 -pix_fmt yuv422p -acodec 
copy /dev/shm/tmp/dxnhd.mov

parameters for ffmpeg converter were copied from this post to ffmpeg-users ML:
https://lists.ffmpeg.org/pipermail/ffmpeg-user/2015-January/025056.html

But I found it quite sad  cinelerraCV (main branch) can't be compiled with 
external ffmpeg 2.8.x (I saw few patches in 
https://git.cinelerra-cv.org/gitweb?p=einar/cinelerra.git;a=shortlog;pg=4 but 
not dared to try and apply them to main branch ....)

This brings interesting question - when next version of Cinelerra will be 
released? (from main branch). internal ffmpeg in main branch very old ....(like 
pre-0.5, from changelog). Is Cinelerra-CV-E not quite ready for replacing main 
version? Because I don't think moving forward TWO versions by basically 1 and 
1/2 developer is good idea ... so, if new release from main branch will be done 
soon -> CVE can become new main version, and old quicktime-based Cinelerra 
moved to branch ....
