Converting ProRes Files to MPEG 2 for Broadcast after edit in FCP
on Jul 4, 2013 at 3:59:27 pm

Hi all,

I'm a fairly new editor working on a low budget web-series, and have just been asked to prepare our episodes for delivery to a broadcaster in the following format:

Stream Type: MPEG-2 Transport or Program Stream
Wrapper: MXF – XDCAM HD422
Essence Format: MPEG HD
Video Codec:Sony XDCAM 422
Video Format: MPEG-2 Long GOP
Frame Size : 1920 X 1080
Aspect Ratio: 16 X 9
Frame Rate: 29.97i
Bit Rate/Type: 50 Mbps CBR
Profile: 4:2:2
Closed Captions: EIA708/608 + SCTE20 (optional)
Audio Stream Type: AES
Audio Bits: 24bit
Audio Sample Rate: 48kHz
Audio Channels: 8 Channels (Optional beyond Ch.1 and Ch2 Left/Right)


There are two sets of files I can convert from:
-ProRes 422 (HQ), 1280x720, 29.97, Linear PCM 16bit, 2 Channels, 48000Hz

or

-MPEG-2, 1280x720, MPEG Layer 3, 29.97, 48000Hz, Stereo (L R)

I've been going through the various settings in Compressor, Mpeg Streamclip and other 3rd party programs to find a customizable solution to match these specs, but no luck so far. Does anyone have any advice or recommendations on getting the material converted?

Thanks in advance for any help... really appreciate this community.

Compressor can't create mxf XDCam files. Also you should always convert from the sequence format which I presume is the ProRes HQ. MPEG is compressed so best not to re compress.

Not sure what software can create those files. You might need to send your ProRes to a facility that can encode. Clipwrap has been mentioned here many times in relation to converting mxf files but I don't lnow if it offers encoding to that format as an option.

Hey Michael, thanks for the info! Very helpful. I'll take a look at Clipwrap and see if it could help in any way, and otherwise we may have to go the facility route as you say, if there's no leeway spec-wise for delivery.

And I appreciate the advice to stay away from re-compressing compressed material (those mpeg files had been created a while ago for delivery to iTunes by another editor)... bit of a silly option on my part, in retrospect.

Thanks again!
S

Make XDCAM-HD422 and rewrap them as MXF with this free file converter:

FC can do the same with the "Export to XDCAM" function, but the files are limited to 4GBs.

Episode (Pro), Sorenson Squeeze and Adobe Media Encoder are alternatives to Compressor.

Adobe Media Encoder has a preset for this.

Do AME makes MXFs?

Rafa, I just checked my CS6 AME and there is a preset for XDCam MXF OP1a streams that match the spec so Steve is right.

Michael,
Thanks for the info.
I have AME but have never explored much the options.
I've never been requested for MXF files.

The company I work for was asked to help re-edit and caption an infomercial. It was originally for the web, and we had to edit it to 28:30 and get captions done.

We outsourced to get the captions transcribed and asked for a .scc file. The spec sheet we got for video delivery from ABC did not mention captions at all.

Long story short: It was a nightmare figuring out how to get captions delivered to them. Neither the original media ingest site nor the outside company that replaced them would tell us what we needed to do to correctly deliver a mac edited movie with captions to them.

Here's what finally worked:

Step one: We used an .scc file provided to us (by an American caption vendor*) to a QuickTime movie with Compressor 4. The specs were 720p, 59.94fps H264 at 45000 Kbps. The .scc file had to start at 00:00:00:00 because the .scc file that started at 01:00:00:00 would not work correctly or at all. (*The first vendor we used outsourced the job to Chile and the got all the idioms wrong.)

(Note: The first time we sent the aforementioned QuickTime movie, it worked. After that, subsequent movies we sent in came in garbled, according to the ingestion department. They looked fine on our end.)

We finally got an engineer that worked for the new ingestion company to tell us that they re-encode most files they receive to .mxf movies.

So hurray, they really want .xmf, not QuickTime or MPEG-2 files, which the spec sheet had listed.

After proofing the captions in QuickTime 7, I used Adobe Encoder CC 2014 and selected the XD HD 50 NTSC 720p60 preset to create an .mxf file. Please note that I had to manually change the preset so that the closed captions were embedded.

That finally worked.

Try this iMixMXF, you can adjust your parameters to meet your customers' needs. And if you want to do some edits, then I suggest you convert your fiels into Apple Prores, if you want to stream them to your customers, then Mpeg-2 would be better.
