Default FAT32 drive and Procoder

I recently tried to convert some Microsoft PAL DV files, into Quicktime PAL DV and MP4 files. This was done on a USB hard drive formatted in FAT32. (So as to be Windows and Mac compatible.) The Quicktime files were converted OK but when I re-set procoder to make the MP4 files, there were no MP4 files at the completion of the processing. Have I missed something or is this a bug?

Using an NTFS formatted drive, it was OK.

Using Procoder v3.05.91

I'm not sure, but I seem to remember there are file size limitations with FAT-32 formatted drives, perhaps constrained to less than 4 Gb.

Unless you are moving around small clips or images with thumb drive, etc., it is best to have all your video editing drives formatted as NTFS.

As you have discovered yourself, NTFS is the way to go.

Files on FAT32 volumes are limited to 4GB maximum size. The volume itself can be much larger, but no file on the volume can be larger than 4GB.

Files on NTFS volumes do not have this limitation..

Thanks for the replies so far. I should have added that the original DV AVI files are all circa 5 mins long, so circa 2 GBytes in size. The MP4 version I was trying to create was for flash video use and so its filesize will be well under the FAT32 4Gbytes limit. Does this change anyones ideas?

The drive is FAT32 so as to be read/write compatible on Windows or Mac OS.

While the file size limitation for FAT32 is 4GB, there is also a limit of 2GB for certain AVI files, which is around 9 mins for DV format. But if the DV files are only 5 mins long they should be well under 2GB, so there should not be any problem with file size.

I don't understand what is happening with the MP4 conversion, but a quick solution would be to use an NTFS drive first, and then copy the converted files to the FAT32 drive. If this doesn't work, it shouldn't be anything to do with Procoder.
