Exporting .mov to .avi and retaining file size

[CathProd]

I just bought Quicktime pro, because I want to export my .mov quicktime file (which I "shared" from I-movie) to an .avi file, so that windows users can view the movie on my website -- some windows operaters have said they couldn't play the quicktime file. The .mov file is 16.7 megs.
Well, when I export the .mov file in Quicktime to an .avi the file size jumps from 16.7 megs to like 300+ megs, no matter what settings I have tried adjusting. Can anyone help me export this .mov file to an .avi and retain basically the same file size for my website?

Thanks!

What bitrate are you saving the AVI at?

[CathProd]

My settings were originally at 95 kb/second. However, I just changed the exporting settings to the following and it came out to 43.8 megs, but the picture is awful:
Video: Compression - Cinepak
Frames Per Second -12
Key Frame every 24 frames
Limit Data rate to 15kbytes/second
Compresssor - Depth: millions of colors
Quality - Medium
Audio: Compression - None
Rate - 22.050 khz
Size - 16 bit
Use - Mono

Any help?

Since you added the "awful!" description, I'm guessing that you want the filesizes to be similar AND you want the quality to be similar...

Well, that depends alot upon what codec you used in Quicktime (for your MOV file) to begin with. The best of all worlds is a codec that has an AVI analog. These are:

• None
  Cinepak
  DV
  ...some 3rd party addons (like DivX)...

Then, you could "losslessly transcode", here meaning it would unwrap the stream from the MOV container and re-wrap it in an AVI container with NO re-encoding. aka Demux and ReMux.

You could do a similar thing with MOV vs. MP4, using the MPEG4 or H.264 codecs. And then you could conceivably use a PC app to LosslesslyTranscode from MP4 to AVI. But that's a little roundabout.

AFA quality, if you can't do the Demux/Remux because of your choice of codec (something other than was listed), you'll HAVE to re-encode.

What codec do you currently have in the MOV files?
What codec do you WANT your AVI pals to make use of?

To be perfectly honest, I'm not certain what a codec is. I just read a brief description of it, but it doesn't seem to help much, given, I'm sure, there is far more to it than the small paragraph I just read.
At any rate, all I want is for Windows operating folks to be able to click on the icon and have Windows Media Player be able to play the video -- AVI doesn't HAVE TO BE be the format -- but it seems to be the only one that WMP will play that can be exported from Quicktime Pro, no?

Thanks.

"Audio: Compression - NONE"
Could mean you're re-encoding the audio from a small compressed audio stream into a large wav audio stream.

"codec" = code/DEcode = a way to compress video/audio and DEcode the compressed file for playback

Lots of codecs out there - DivX, Cinepack, h264, Mpeg

AVI, MP4, MKV are "Containers" - envelopes in which you place your compressed video and audio files.


Quicktime is an odd beast when it comes to file creation in the PC world.

[Cornucopia]

Open your MOV file in QT player and do Ctrl+I (or Apple+I for Macs) aka Show Movie Info.

Under [Format] it'll give you the codec(s)--both Video and Audio (and usually in that order) and their specs.

In fact, if you'll let us know some of those other info as well, like [Data Rate], it'll be much easier to estimate what you're going to need to give those AVI folks.

How do I find the data rate of this present file? I can change that when exporting it into the avi, but I don't seem to be able to find what the data rate of the present .mov file is.

Thanks
