No particular reason to output small files I guess. I generally like having multiple smaller files so that damage to a file only wipes out a minute or so of the recording, instead of the whole thing. I figure there is no sense in recording a large file if I know it has to be edited anyways, and I get a warm fuzzy from seeing small, closed files instead of large, continuously growing files. Another reason is that whenever one sees HDTV content posted for download in unmentionable places it is in 100MB chunks with commercials, etc. edited out, so it seems to be a common thing. I figured that everyone was using HDTVtoMPEG2 for their editing, but maybe not if it has problems with that size files. Haven't tried VideoReDo to see how it behaves, and would prefer not to for obviou$ reasons. I'll experiment with different file sizes, and now that 1.11.83 is on the web site I'll try that too.
Just so I'm clear on which file size you're concerned about, is it the input files (which are 100MB) or the output files (which I was wanting to make 100MB)? I might be stating the obvious here, but I had no problems opening a single 100MB file and trimming parts out of it to make a sub 100MB file, but working with multiple 100MB files led to the problem. It wouldn't be the commercial scan specifically that caused the problem, since the result is just some include/exclude regions like with the single file. The only obvious difference between the two cases is the number of input files. If I continue running into issues with the small input files I'll stitch them together into a 6.5-7GB file and try that as well.
