Over many years, I have made 50+ Hi Def Bluray discs of between 30 to 60 minutes in length, (incl. music, titles, maps etc.) of our travels around the world. I have discovered that the shorter ones can be burnt (as a ISO file) at the highest quality, copied to a BluRay disc, and that they will play on my Sony player (as a well as my computer).
The longer ones, I usually have to reduce the quality MPEG2 Hi Def because, although they still play on the computer, the picture often stutters on Bluray player play back - I assume because its processor cannot buffer the data quickly enough. (I could well be wrong and stand to be corrected). These discs do actually play successfully on my quality Windows 10 desktop computer (Power DVD)
On a recent 60 minute project, I burnt it at the higher quality level by mistake, and did not check the Bluray disc on my player before deleting the project, and have subsequently found that the disc will not play on my BluRay player. The ISO file of the project and the BluRay disc both play perfectly on the computer, and I was wondering if it was possible to 'reverse process' the rendering to get the project back to AVI status so that I could import the project (as one block) back into Power Director and re render it to the lower MPEG2 HiDef quality that should play on my Bluray player.
I hope you can understand my problem. It breaks my heart after putting in so many hours work, that I am unable to play it on to my TV via my Sony BluRay player.
I have tried using a media file converter program without success.
Any ideas gratefully received.
