UniFab 2.0.0.1 Converter Often Does Not Properly Handle Video

[Mauser]

I have converted about 1,000 .mpg videos to H265.TS files with UniFab 2.0.0.1 (most in batches of 100 files each), and I now find that about 50% or more of them have not been done correctly, and they will not play in VLC. No errors were encountered while doing the conversion tasks, but Media Info shows the Video stream to be "JPEG 2000" instead of the normal "HEVC".

The problem is not specific to any file, and re-running the task may or may not convert it properly. For example, out of 10 .mpg files I tested today, 7 of them were bad and showed JPEG 2000. When I re-ran those seven tasks, 4 of them converted properly, but 3 still came out as JPEG 2000. When I re-ran those 3 tasks, 1 still shows JPEG 2000. This file name is Broken Lance (1954).mpg, and it is the last task I ran before submitting this feedback.

I do not know if this feedback will send you the logs or not, so I will also post about this problem on the support forum.

Here is an example of the MediaInfo for a normal converted file that does NOT have this problem:


And here is the MediaInfo from the last converted file I did that DOES have the problem:

Both of these conversion tasks were run using the same profile and settings. The first one, Broken English (2007).mpg, did not convert properly two times, then did fine on the third try. The second one, Broken Lance (1954).mpg has failed to convert properly three times now, but it did convert fine on the fourth try.

I have attached the logs to this post, although I do not see them (so I will attach them to a follow-up post).

Just trying again to upload the logs for this problem.

This problem is NOT fixed with 2.0.0.2.

2.0.0.4 This problem is still not fixed.

I did a full removal of UniFab and a clean reinstall from the Offline installer, and my first tests of the Converter still showed that it was randomly crating some output files as JPEG 2000 instead of the HEVC format specified in the selected profile.

As I have already told your tech support team in an open trouble ticket, this problem is only happening for me when using the AMD hardware encoder - I cannot duplicate it when using a Software encoder or on a computer with an Intel GPU.

This problem is not tied to any specific input files. I have a set of 8 short video clips I use for testing (already uploaded for your tech support team), and every time I run the converter tests with these 8 files, some random selection of them are output as JPEG 2000 and others as the expected HEVC.
