  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

avid mxf red workflow

hello all
this is a public apology
I've already done one in private but i thought a public one wouldn't go amiss.
I have used some of Mike Costelloe's footage in my test videos (now removed)
Click to expand...
I remember one IBC going round a corner and being surprised to see some of my stuff on a 60" plasma. The manufacturer had "forgotten" to clear it with me first and I was none to chuffed either... Its easy to overlook such things in the excitement of making something happen.
 
Jamie,

No worries, no harm done I'm sure but thanks for removing it and the apology. It is usual to see one's footage in many places, but my daughter Amy wasn't too happy about it. :yikes:

Mike Costelloe
 
Tim
that's exactly right my common sense had been replaced by this
"ohmygodican'tbeliveitworkedQuick-do-a-video-ornoonewillbelieveme!!!"
and the only stuff i had was Mike's.
there you go.
I'm so glad he's not too mad at me though,he's one of the good guys.

FUZE NEWS FUZE NEWS FUZE NEWS.....
right.
had chats with lovely developer chaps today.
they were a bit amazed at how much an idiot like me had achieved.
Boss and developers all agreed to release it with the same functionality it has now but with a PROPER GUI and....25fps support!!!!
(i told you it would be here first)
so don't panic everyone it'll be out soon.
the 1st edition will probably be available through KAGI (a shareware type site) fo the massively hiked up price of......$49
I am "lead talker to red people around the world" on this project so ANYTHING you want to be in a future version PM me or post out loud.
I'm really pleased that it resolved itself like this. I thought it was dead and buried but
Lo I riseth from the ashes like a small furry mouse with asbestos pyjamas.

seriously get your requests in now there's talks of JamFuze PRO (goodness knows what that means....)
j:)
 
i request more specs for MXF files.

i want SD MXF files as well. Not just DNxHD.

Now that this is getting VERY real, and talk of JamFuze Pro is out there, I think as many permeatations as possible should be offered, as many AVID editors seem to still want to work in SD world. Is this possible? Am I asking for something silly?

Glad to hear the news Jamie! You deserve it!
 
more mxf types

more mxf types

for 25fps DV mxf is easy peasy (even i can do it)
for 23.98..... not so much
most SD things don't do 23.98 they only do 29.97. I'm not sure how you'd track back to do the online pull from the R3D but AVID editors (and MichaelP) may know of an easy way to get it (the 23.98 timecode) out in the EDL at the end of the edit...chime in if you want it.
Boss DEFINITELY wanted 25fps DV done- so it shall be.
the mjpeg out of redline looks nasty so don't know about 15:1s and stuff like that but maybe if i speak to Tim and/or the ffmpeg guys it could happen somehow.
it will just take a bit longer as there's an extra encode step.

i did a test 100 R3D file -dnxhd36 offline encode today-worked fine
made a 1min45s sequence from those files (about 60 or 70 different files used)
ONLINE PULL to DNX185 (25fps) perfectly.
cool.
keep suggestions coming.
my "copy and paste into an email" kung fu is strong...

jamie,

previously i had asked asked about adding a dnxhd 175 option in the 'offline' version for those of us that do more tv work and might not necessarily want/have to go back and reconform from the .r3d files. you didn't think it was a problem.

could it be added?

david
 
175 for "offline"

175 for "offline"

OK i will ask for that to go in.
175....we're getting into territory where "offline" doesn't accurately describe what's going on.
Should that bit of the process be called something else?
Prep?
1st stage transfer?
something else???

I passed all the code and scripts and stuff over to the posh developers today so we'll see how it goes from now.
I expect a few phonecalls (ie why the hell did you do it this way Jamie you loony...) tomorrow but I'm grading 2 short films.....both shot on the RED camera!!!
weird coincidence.
j
 
I have tried, and failed to get RedLine piped into ffmpeg, RedLine seems to refuse to use pipes!
I have also tried letting ffmpeg chomp on the mov before it was completed, *but* RedLine doesn't seem to use the "optimise for fast streaming" tag, so the important header info is at the end of the file, not the top!!!! Grrrr.

Getting ffmpeg to demux to a video and wav files simultaneously speeds things up a bit compared to doing it sequentially like JamFuze, but that's about the only optimisation I can spot.

The other thing of note is that Interplay still barfs on the writeavidmxf files. This is a know issue awaiting a fix.

Avid mjpeg is best made with mjpegtools not ffmpeg...
it will just take a bit longer as there's an extra encode step.

I found that recoding rather than just demuxing added very little overhead and could be done in the same pass

How did you select the actual 60 or so clips to pull from the original 100 or so? That's where the FCP XML really scores.
 
online pull and other stuff...

online pull and other stuff...

hey tim
the online pull is sorted out by the avid EDL from a decomposed sequence this gives you everything you need just to do a relink and the sequence just rebuilds beautifully.
Avid knows its stuff when it comes to "tracking" shots i guess.

the ffmpeg stuff is good to know. I know 1st hand how much of a whizz you are with that.
mjpegtools is something i've not come across before..
so i would (for avid 15:1s Standard def type things) make redline output a 640x480ish or 720x405 thing (redline doesn't seem to handle non 4:3/16:9/2:1 ratios easily) in say uncompressed or h264 because that seems to go very fast
then use that to feed mjpegtools to make the 15:1s mjpeg based avid mxf?
is mjpegtools out there on the interweb for me to look at?
i would have defaulted to using ffmpeg I think (only because i now know a bit about how it works)
I have some "playtime" tomorrow so i can investigate.
It's a bit weird not being the developer any more.
I can't really just write it and stick it on my website and let you guys know. Odd.
but i'll do it just to find out anyway.
cheers
I still haven't managed to pin down Boss and ask him if we can integrate with clipfinder. I will try and ask that tomorrow.

Off the top of my head I cannot remember the settings for 15:1, I know SC had to tweak them by eye.
The code is all in the Ingex sourceforge CVS along with writeavidmxf. I think mjpeg tools expects raw input, it certainly won't like h264. You could always try to do it with ffmpeg since you are not trying to do it real time from a live stream, however I have no idea of the best settings. (Frame size is 320x288 istr)

My real question though is why on earth make 15:1 for HD material, you won't see focus errors etc. I thought DV had become the standard for HD offline, which is why your boss wants that option in.
 
15:1

15:1

yep DV was as far down as i wanted to go but choice is important if people are paying for stuff...
if it's an option in the AVID i guess people want it as an option in whatever i produce.
Actually... DNx36 was as low as I wanted to go but I understand the reasons for DV (more machines capable of editing it/slight space saving etc etc)
so it'll be done as soon as me and chris figure a way of doing it easily.
I think ffmpeg may be it. i couldn't find any real easy way of FILE transcoding with mjpegtools cos i am stupid.
ffmpeg is cool and will probably do the trick.
j
 
I am almost done with the SD version of the transcode process. Involves MPEG Streamclip and MetaCheater since it does the proper timecode conversions for accurate 30/24 or 25/24 tracking when working in SD.

timecode tracking

timecode tracking

hello MichaelP
if jamfuze puts the DV 29.97 (1st frame) timecode in the START column but the original R3D timecode in the TC24 column would the avid track it all perfectly so as long as you output an edl with TC24 as the "source" timecodes it would all work?
I think i can do that because i had to figure out how to take the ale to pieces....
cheers
jamie
 
That is basically it - also a Pulldown Look Up Tape where "A" frames map to non drop timecodes ending on :x0 and :x5.

Michael
 
hey michael. i am trying to put DV25 files i have made through Red Rushes export and then AVID import into 23.976 NTSC formatted AVID project, but the clips, when played, have a timebase of 29.97. I would like to cut in 23.98/NTSC, with these DV25 MXF clips. What I am doing wrong? Go easy, I am an absolute AVID novice...
 
FYI, camera is at 23.98, editor wants to cut on DV25 MXF files in Media Composer. Then will need to conform at another facility using the EDL output from Media Composer. My goal is to make the DV25 MXF clips for the editor and make sure the metadata is all correct (I used Metacheater for this) so the conform goes smoothly.....
