Making a Broadcast Master

[Vishal Jadhav]

Hi,

I am editing in Premiere Pro CC 2014 on a Windows machine.

The edit is a Documentary of 48 minutes and need to create a master for distribution which is required in "Apple Prores HQ 422 PAL"

I understand that on windows machine its not possible to create a Pro Res file directly from Premiere pro cc 2014

Can any one suggest a method that worked for broadcast in such a case.

thanks

As you cannot export ProRes from a Windows machine, I would try Avid DNxHD format which will be quite comparable in quality. You could then take that file to someone with a Mac and get it converted to ProRes. Any generational quality loss should be virtually undetectable.

Thanks

2nd that - export to DNxHD then get someone with a Mac to transcode to ProRes.

I'm surprised that the broadcaster will only accept ProRes - I've found they normally prefer DNxHD or even an XDCAM export as they are more universal.

Thanks John, Jeff

I think i would be able to do a DNxHD export , i was just looking at the guidelines and i found some strange things like i need to deliver 2 copies of the Master with below audio setups

Audio set up:
Track 1 and 2: Full Mix
Track 3 and 4: Full Mix minus narration

As i see it DNH HD may have 2 tracks only or am i missing some point.

Also is there any program which can encode Prores from DNxHD on Windows.

1. DNH HD from Premiere may have 32 audio tracks tracks.
2. ffmpeg can encode Prores from DNxHD on Windows ( https://en.wikipedia.org/wiki/FFmpeg ).

Thanks Juris,

I managed to export out DNxHD from Premiere and then encode it via ffmpeg to prores.

Used the "AnotherGUI" as the front end and it was very neat to operate.

thanks a ton folks it was very helpful

Hi ,

I think i could make the Video part of this work however the audio part of the mix is something that confuses me,
I have currently 5 audio tracks, the first 4 are with foley & music the 5th one is the Voice over now i need to make only one export that has 4 Audio channels that
Track 1 and 2: Full Mix
Track 3 and 4: Full Mix minus narration

The method adopted by me was that i made a new sequence with multichannel setup having 4 Audio channels and mapped them
For Channel 1 - Tracks 1+2+3+4+5+6 Since this is to be with full mix
For Channel 2 - Tracks 1+2+3+4+5+6 Since this is to be with full mix
For Channel 3 - Tracks 1+2+3+4 As Track 5 has narration
For Channel 4 - Tracks 1+2+3+4 As Track 5 has narration

Attached the audio mix setup image used.

Is this the right way of doing it as my original sequence was only a Stereo Audio setup, i needed to make a new sequence with the multichannel Audio setup.

Now Magix Vegas Pro v14.0.0.201 can import and export Prores on Windows.

Hi,

This is a topic i started but finally a solution which may work.

I used Premiere pro to export DNxHD in a quicktime wrapper with 4 channels of audio which is possible solution over windows.

From there i used ffmpeg to encode the video into Prores 422 HQ and copied out the audio channels as it isthere by resulting into a Prores 422 HQ with 4 channels audio.

for ffmpeg the command line code you may need is as below

ffmpeg -i filenamet.mov -map 0 -c:v prores_ks -profile:v 3 -c:a copy resultantfilename.mov

thought if a solution worked its good to share
