Page 1 of 1: MOV to AVI Conversion Guide


Please note: New version of QuickTime/MOV files cannot be converted by this method, and so, you should use the updated QuickTime to AVI (using QuickTime Pro) Guide instead.
The program used to protect these files isn't a $500 program called Sorenson Video but a freeware program by apple called Plugin-Helper. There is a Win32 And Mac version but only the mac version can protect the movies. This guide will hopefully teach you to convert MOV files to AVI/DivX, using mostly free applications.


Required Software

Here are the app names to use to convert protected mov to avi :

  • RAD Video Tools - Convert mov video to avi - May not convert audio
  • TMPGEnc with the QTPlugin - Convert mov audio to Mp2 - No Video
  • VirtualDub - used to join/multiplex the converted audio and video



  • Instructions

    1. Use RadVideo to convert the MOV file to DivX/AVI. Leave all the settings alone, unless you know what you are doing. The audio may not be converted by this tool (although some files will work fine), and if this is the case, we'll need to separately convert the audio in the next step.


    2. Please only follow this step if the audio did not come out properly in the previous step. Install the QTReader VFP plugin for TMPGEnc (copy the .vfp file into your TMPGEnc directory) and convert the audio to a .MP2 file. You can then convert the MP2 file to WAV using this guide.


    3. The last few steps involves putting the (converted) WAV audio file into the AVI/DivX file using VirtualDub :


        1. Start VirtualDub and load in your converted DivX file.


        2. From the "Video" menu, select "Direct Stream Copy".

          VirtualDub's Video Menu


        3. From the "Audio" menu, select "Full Processing Mode".

          VirtualDub's Audio Menu


        4. From the "Audio" menu, select "AVI Audio" and load in your normalized and/or amplified WAV file.


        5. From the "Audio" menu, select "Compression" and select "MPEG Layer-3" and the same or lower bitrate/attributes (eg. 128 kBit/s, 48000 Hz, Stereo) you used earlier to make the DivX movie (in FlasK MPEG).


        6. From the "File" menu, select "Save AVI" to save the AVI to include the normalized audio. This shouldn't take too long as only the audio is re-encoded/compressed - the video will be left along.


    Additional Notes

  • If the above method fails, i use Ulead VideoStudio 5 to convert to avi


  • If that fails, use Dumpster to edit the resources of the mov file. How to use dumpster: (read the readme file distributed with the app)
      1. Make a backup copy of the mov file
      2. Drag the mov file onto dumpster (easy right)
      3. look for the string "NASV" and change values to all zero's


      4. *This method doesn't work with fullscreen mov's because it has the sprites and all that extra JUNK so you'll be unable to find the "NASV" string.

    Here is an alternate method that is a bit simpler and does NOT need Quicktime installed. Install AVIdemux. [Its free and safe - no registry changes: www.avidemux.org or http://codecguide.com/video_conversion_pack.htm ] Open the MOV file in AVIdemux. Set Video to "MPEG-4 ASP" (Xvid4 or lavc). Configure the codec as you please or use the defaults. Set Audio to "MP3 (LAME)" Configure it as you please or use the defaults. Set Format to AVI. Save the file (add ".AVI" to end of filename). If you get an error "Encoder initialization failed - Not activated" followed by the "Error initializing audio filters" message, then try clicking on the Audio Filters button and turn on "Resampling (HZ):" (you may be able to lower the resampling to as little as 16000 hz for files that have only talking), and then Save again. With AVIdemux, you can also edit the file (cut out unwanted parts). Its a great little program similar to Virtual Dub with built-in codecs and support for more file types.
