Hi,
I need to convert movies that I made with quicktime to mpeg-1 format, because the journal to which this movie (and the article it accompanies) will be submitted only accepts mpeg's. I've used FFMpegX to do this many times before, with no problems. However, the frames being converted at present are bigger format than before --- 1072x720 --- and I cannot get the converted movie to retain the right frame size. Even when I select "unconstrained" in the menu, it changes the output to 972x720 which messes up the aspect ratio and the quality of the results. The really irritating thing is, I ran into this a couple weeks ago and somehow managed to fix it, but of course I don't remember what were the magic settings that worked. Has anyone else run into this problem, and if so, how did you get around it? Many thanks for your help!

The most hard core Mac fanboy that I know of admitted to me that he runs Windows on his Mac in a virtual machine because there are some programs that simply have no Mac equivalents. -
Thanks Baldrick for your cunning plan! Originally I ignored that program because the listing on the Video Software List under "Type" says Mpeg StreamClip is Windoze only, and a search on that site for Mac-compatible software came up with very little. After seeing your answer I went to the original website and there's a Mac version too. Someone should update the Video Software List.
Thanks for your help too, jman98, even if we are of different religions ;^> . I have never run any Windows programs on any of my Macs, starting over 20 yrs. ago. Don't intend to break that record either! -
follow-up for completeness: MPegStreamClip does not convert QuickTime to MPEG-1. I have contacted the authors to find out whether this capability will ever be included. OH well.....

Perhaps your output file was fine all along... -
Case points out an important fact worth keeping in mind: QT reports the resolution it is currently using for display, not necessarily the fundamental resolution of the file. The basic rule is to ignore what QT is telling you about resolution -- use something else.
