converting a spot to mp3 (audio and video)?

[Shane Ross]

Aren’t MP3s audio only? I never heard of a video mp3. There is mp4 (MPEG 4) that is both.

What is this for?

that’s what i had thought, too. client says they need and “mp3 version of our latest spot for inclusion in a PowerPoint presentation”.

i never use PP, so not sure if they really know what will work…

anyone else have an idea here??

Mp3 does carry video.

I recently had to encode moves for smart card and needed to deliver in this format. I believe I had to use cleaner to do this as it is a muxxed file.

Compressor or QT Pro did not do the trick.

Well, in the technical sense MP3 IS only audio. It’s the audio-track of MPEG-1 video. So if you have video with it it’s not really an MP3, it’s an MPEG-1 video file.

But I don’t think we need to get technical. I doubt Mortimer’s client literally wants an MPEG-1 file. It sounds to me like they just want something that will play in Powerpoint, no matter what that is. You should search the web to find what formats Powerpoint accepts and just pick the one that looks easiest for you to do.

i read about Audacity, but it didn’t work (unless i did something wrong). i dug into PP some more, and my ancient version (Windows PP 2000) will play videos that are labeled, “Windows Media Audio/Video”, and “movie file (mpeg)”. after testing several codecs out of FCP, it looks like “mpeg-1” (under web download, QT 6 compatible) was the only successful candidate out of FCP, but the quality certainly wasn’t all that good – hopefully good enough? i’ll soon see… : )

thanks Jeff. i think that’s exactly what i found out by trial and error out of FCP. MPEG-1 seemed to do the trick!

“… MPEG-1 Layer 3 (or MP3) is a 1- or 2-channel perceptual audio coder that provides excellent compression of music signals. Compared to Layer 1 and Layer 2 it provides a higher compression efficiency. It can typically compress high quality audio CD data by a factor of 12 while maintaining a high audio quality. In general MP3 is appropriate for applications involving storage or transmission of mono or stereo music or other audio signals. Since it is implemented on virtually all digital audio devices playback is always ensured

Thanks to its low complexity decoding combined with high robustness against cascaded encoding/decoding and transmission errors, MPEG-1 Layer II is used in digital audio and video broadcast applications (DVB and DAB). It is also used in Video CD, as well as in a variety of studio applications.

Layer 3, or as it is mostly called nowadays
