converting AVI to MP4 - unknown error 32771

When trying to convert older AVI content to medium MP4 quality (having recently imported Sony Digital8 DV-AVI format using PMH import), at end of the MP4 conversion process the Conversion Results window displays, "An Unknown error occurred. (Error code: 32771)", immediately after which the generated MP4 is deleted.


process: Convert to MP4 and Save:  Video Quality: 1920x1080 25p/30p 14 Mbps


Following the error, I restarted PMH and tried again - the same problem occurred again.



As a workaround, I used the opensource "VirtualDub" program, created a copy of the original AVI file (simply performing a "direct stream copy") of both video and audio.  I then attempted to perform the conversion of the copied AVI to MP4 -- which completed successfully - no problems detected - resulting MP4 played fine.



OS: Windows 7

PMH Version:



  FIle Size:  2.97 GB

  Video Format: DV / AVI

  Audio Format: PCM

  Duration: 14mn 15s

  Total bitrate:  29.8


OUTPUT (having used the copied AVI file):

  File Size: 1.37 GB

  Video Format: AVC / MP4

  Audio Format: AAC

  Duration: 14mn 15s

  Total bitrate:  13.7 Mbps

Re: converting AVI to MP4 - unknown error 32771

Any update on this problem?  I have the same problem.

Importing from a Sony Handycam  DCR-HC52 4mm tape via firewire.  That seemed to work good.

Play Memories Home 5.4.02

Microsoft Windows 10 Pro


I tried your virtual Dub program.  I don't see how to do all of my files at once.  It converted one at a time straight to mp4.
