Don't know what you problem is/are but length of the .mov is not the issue (I put my money on it, hehe).
I'm trying to convert some video files I took into a format I can use in Pinnacle i.e. avi or mpeg, for some reason my Panasonic digi-camera records in .movs.
The problem is the files are at least 5min long each, except for one, and whenever I've tried to open them in a converter the converter screen freezes. It continues to use as much of my cpu as it can although the RAM usage steadily decreases. This is just opening the file, not actually hitting the 'convert' button yet.
The smallest file was converted successfully.
I thought I'd try splitting the movs into smaller files to see if that would make it easier...but they have the same problems as the converters. In fact I think they're just converters with the addition of being able to split the files.
WinMPG Video Convert
Any Video-Audio Converter
Video Splitter Remove
...and another one which I've already deleted.
ps. I'm going on holiday for a couple of days, but any responses in the meantime would be great
