Where exactly did you get the clips?
Thanks so much for replying.
Here is the cam. Its not mine:
It's a Sony PMW350K
XDCAM EX 2/3"-type Shoulder-mount Camcorder with Lens Package
I have this problem with a couple of different MP4 cams. I have to bring it in Vegas 1st & pre-edit the audio then bring it over to PP CS5. Is there something I'm missing?
Can you describe what you mean when you say you only "get" one audio channel, instead of four? Does only one audio channel import, or can you only hear one audio channel?
Only 1 channel is importing in CS5.
Next describe the exact steps taken with the media, from camera to PP's bin.
The files were sent to me on a HD. I copied them to my Raid 0, opened a new project, did a typical file/import, dragged 1 of the clips to the make new sequence (item), A new sequence appeared with the clip in it & only 1 audio track was present.
I uploaded a 10meg clip
here is the url for download:
The fix is in:
It appears that Mono 1 and 3 are the same, and Mono 2 and 4 are the same, so technically, I think you could get away with just 1 and 2. Do you want all four, or just the first two? I'll help you with a script to accomodate, either way. Are you using Windows?
(PS: The MP4 imports with just a single mono track, as you described. Hard to say if this is a bug or just a limitation. Might be worthy of a bug report, regardless: Adobe Feature Request/Bug Report Form)
Hi Colin thanks for the help.
I put the clips in Vegas & pre-edited the audio just leaving the tracks that i wanted than I made a new HD clip combining all of them & brought it into PP. What a pain but it allowed me to complete this project.
I get mp4's from different shooters & they each put different mics on diff channels so each job is different.
I only see 1 mono track in PPcs5 when I brought these mp4's in not 2, just 1, pretty weird huh. I hear 5.5 is on its way.
Yes I am windows based. I think CS5 is not set up to handle these clips correctly. What kind of script are you refering to? What does it do?
It's pretty simple... when you know how
- Get ffmbc - FFMedia Broadcast . This is a customized build of FFmpeg that is more geared toward broadcast formats and applications. The latest "official" release (0.5) will work.
- Open the archive and find the "ffmbc.exe" file in the "bin" folder. Drop it into the folder with the MP4s--or if you know how to set up a custom path, you could do that too.
- Create a new text file called something like "mp42mxf-4mono.bat" making sure that you can see file extensions; you need to have the .BAT extension. Make this file in the same folder as the MP4s and FFmbc.
- Paste the following into the batch file:
for %%a in (*.mp4) do ffmbc -i "%%a" -vcodec copy -acodec pcm_s16le -f mxf -y "%%~na".mxf -acodec pcm_s16le -newaudio -acodec pcm_s16le -newaudio -acodec pcm_s16le -newaudio
- Save it--again making sure it has a .BAT extension--and then double-click it to run it. It will rewrap all of the MP4s as MXF files that will import into Premiere. It will also retain the original four mono tracks as four mono tracks in the destination MXF.
That's all there is to it. Save that script, and you can recycle it whenever you get a batch of these types of problematic files in. Note that it's a completely lossless rewrapping, and should only take a few moments (or minutes, if you have a lot of footage, I suppose). Let me know how that goes.
The files were sent to me on a HD.
Out of curiosity, did you receive just the MP4 files, or the entire folder structure of the original media card?
I only received the mp4's. Nothing else.
That makes me wonder if that is the cause of this issue. The proper procedure for solid state media is to copy the entire folder structure, and use Premiere Pro's Media Browser for import, rather than File>Import.
You might suggest your client send over the full contents next time. Things may work better.
Had the same problem with MP4 files.
Been looking for an answer when I found this post.
Used your solution with great success.
Thanks a lot!
P.S. I Wonder if CS6 solves the issue...
