This is gonna sound a little strange, but I assure you I have tested this a lot. The problem is that MP4 output video files from both UniFab Converter and Compressor will not play properly with my MECOOL KM2 PLUS video player and Kodi application. Files created the exact same way with DVDFab 12 ALL play perfectly.
More detail:
I have many thousands of .mpg files that I have ripped from home-recorded DVD+R and -R discs. These files are not compressed, and they all play perfectly.
I have recently been converting/compressing all of them with DVDFab 12. I use MP4 as the output profile simply to make it easy for me to see which files I have compressed this way - I have a lot of other MKV video files that are either downloaded or ripped from commercial movie discs with DVDFab, so I did not want to use MKV output from these newly compressed files.
When I convert these mpg files with DVDFab 12, I use the (MP4.H265) profile that come with DVDFab 12 (no changes), and I set the Video Quality to Standard. I have converted over 1,000 of them so far this way, and every single one of them plays perfectly with my MECOOL video player.
Yesterday I converted 200 of the same mpg video files using UniFab 2.0.0.0, and NONE of them play properly with the MECOOL video player. The audio plays fine, but the video is either not there at all or frozen. Unfortunately, all of these UniFab output files do play fine with any video player on my computers, so I cannot duplicate the problem without using the MECOOL KM2 PLUS video player.
For additional testing, I re-ran the same conversion tasks with UniFab using MKV output profile, and those files DO play fine, so the problem so far is very specific to the UniFab created MP4 output files.
I have carefully compared the MediaInfo details from the same files created with both DVDFab 12 and UniFab, and other than some minor differences in Overall bit rate and Bits/(Pixel*Frame), there is nothing different at all, so I do not know were else to look for the cause of this problem.
While it is tempting to just say that the problem is with my video player, I want to repeat LOUDLY that the MP4 output files from the exact same conversion tasks done with DVDFab 12 ALL PLAY PERFECTLY, while NONE created with UniFab play correctly, so UniFab ABSOLUTELY MUST be changing something in the MP4 output files that is causing the problem.
(but I also must acknowledge that the files do play with everything else I have tried)
