Exporting multi-audio channel C300 footage to use in Premiere
on Apr 18, 2019 at 11:15:20 am

Hey,

I'd love some help with this... I've used Final Cut for years and carried on into FCPX. I have to work in Premiere for a new project though and having a problem with something.

I imported some C300 footage into FCPX. I don't have the original cards just what was imported into FCPX.

I tried importing this footage in Premiere but it only reads it as a single audio track - no video.

I exported the files from FCPX as Master Files (I realise this isn't ideal but...). When I import these into Premiere, the audio channels are mixed into one.

Is there a simple way to export the files without compression and without turning 4 audio tracks into 1?

I bought XtoCC to try exporting and converting XML but Premiere can't read that either.

Many thanks!

Eleanor

I has questions:
1. Did you re-wrap or transcode the footage prior to ingest?
2. Does everything look as it should inside FCPX, including number/config of audio channels?
3. Where are the files that you tried to import directly into PPr?
4. What versions for OS / FCPX?
5. Do you have VideoSpec or something similar? It's a small app that analyses media files and shows detailed information about tracks, encoding, container, bitrates, etc.

Hi Doug,

Thanks so much for your speedy response.

In answer to your questions:

1. Did you re-wrap or transcode the footage prior to ingest?
I don't actually ingest it so I don't know. I think they just used the C300 plug-in for FCPX.

2. Does everything look as it should inside FCPX, including number/config of audio channels?
Yes, it does.

3. Where are the files that you tried to import directly into PPr?
I tried importing the files saved in the FCPX "Original media" folder. That only showed as audio in PPr. I then exported them as Master Files and saved them in a different folder and here the video showed up but the audio didn't (I guess this is where I need to re-export them but do something to ensure the separate audio channels are conserved? Not sure of best way to do this).

4. What versions for OS / FCPX?

High Sierra - 10.13.6
FCPX 10.4.6

5. Do you have VideoSpec or something similar? It's a small app that analyses media files and shows detailed information about tracks, encoding, container, bitrates, etc.

No, I don't....

Thanks again for your help and any thoughts you might have.

Eleanor

Just to be clear, we're talking about XDCAM with 4 audio channels, correct? I've got some C300 cards that have stereo audio, and none with 4 channels.

Yes, it does.

If I'm not mistaken, PPr will write data to your source media after ingest, which could cause relinking issues in FCPX. I'm not 100% certain of this, but do recall others having problems related to non-matching file sizes / modification dates with their camera originals.

High Sierra - 10.13.6
FCPX 10.4.6

No, I don't...."


Check one of your source files with this, and maybe post a screen shot of the details. Could be a codec issue, or something to do with the way the files were transcoded:
