Using TMPGEnc Plus 2.5: The problem lies after selecting the file (where there is no problem and no error message is displayed) and going to stage 4/5 on the project wizard (bitrate setting). Here it tells me the estimated file size will be 153.56% of the disk size. Average video bitrate is 2000kb/s, and i cant reduce it to any less. Audio bitrate is 384kb/s. The problem seems to be in the fact that its telling me that the length of the video file is 371mins, even though i know it is only 140minutes long (which is shown in Windows Media Player and other video playback software). So somewhere along the line, it is recognising this video as a lot longer than it should be, so the output file will be too large. This now happens to all my AVI files i am trying to use, where with each file, the recognised source length is well over 2 times what it should be. I don't know why this has suddenly happened, because two weeks ago this software was producing output files with no problems. I have tried updating the program software, but i have had no luck with that. It just seems strange that any other video playback software i use sees the video length as what it should be, its just TMPGEnc Plus which sees it as longer than it is. Thanks in advance for any advice you can give me.
