Thanks for posting the clips and the info about ffmpeg.
Could you explain in detail how to use it.
I've tried to demux the clips, but can't figure out how to use the script.

Have you downloaded ffmpeg and got it working?

To test it, put all files in the ffmpeg folder and try running it from a dos prompt.

Try
ffmpeg -y -i inputfile.mp4 -vcodec copy -f mpeg2video outputfile.m2v -acodec pcm_s16le outputfile.wav

If you want to run the script from C:Program Files or other you must set the path in you environment.

Andreas,
I have been reading your blog with great interest while waiting for my camera to come in. It finally has. The clips import beautifully into speededit but Premiere cs3 shows the audio track as empty of wave activity. This was also the case of the sample files of yours that I downloaded, except one. I tried you ffmpeg script to mpeg2 and it split my clips into separate audio and video but with the audio now present. Is it possible to modify the script so the export is to a single file with both the audio and video in this playable format? I appreciate anything you can suggest.
Regards,
Jim Spatz

Jim, send me an email using the contact form and tell me what you want to get and I'll see what I can do.

I made an ffmpeg wrapper so it's just point and click. I figure other people might be interested so I'll temporarily post it here:

If you set your import settings in Avid properly (maintain, square pixels and 709 color space), Avid will Fast Import your quicktime with no additional transcoding (besides the mp4 to quicktime translation). This isn't an Avid product and it's the first version, so use at your own risk. That said, it's worked successfully for me for getting footage into MCSoft on both PC & Mac and also into a Nitris.

Thanks Brad.

I'll try it out but over the holliday I don't have access to any NLE's to try on. I will post this on dvinfo.net later also.

Could you send me a message using the contact fields so that I get you email adress?

The problem with the native EX audio is its Big endian (a la motorola) not little endian (a la Intel) which is why its mute unless you convert it.

What have people done about preserving the timecode of the clips?

Andreas on 02.02.2008. 13:39

At this moment I guess they don't care about the timecodes. That will work when the NLE's get full support. The ones using ffmpeg to convert the files are more interested in getting files that can be edited before the NLE's get support for it.

Any idea if this will allow import to After Effects?

Andreas on 02.07.2008. 19:16

I think AE can import EX1 files by it self now.
