In trial. Worked great for 3 days. Now preview timeline is messed up.

It seems that this is already my configuration.

The missing audio is in the TVE source stream.
Run redetect commercial against one of those recordings that shows missing audio and examine the comskip log.
Search for 'Jump' and 'Strange' in the log.
On those lines in the log you will see the PTS jumps forward or backward in time.
Here's an example of one I had
Code:
Strange audio pts step of 2959.04642 instead of 0.00000 at frame 509
Jump in base apts from 17.52342 to 2976.56930, delta=2959.04588
Strange audio pts step of -2959.17342 instead of 0.00000 at frame 512
Jump in base apts from 2976.56930 to 17.39537, delta=-2959.17392
Strange video pts step of 2959.16028 instead of 0.03387 at frame 512
Strange audio pts step of -2959.17342 instead of 0.00000 at frame 514
Jump in base apts from 2976.56932 to 17.39540, delta=-2959.17392
Strange video pts step of -2959.10738 instead of 0.03387 at frame 514
Strange video pts step of 2959.16028 instead of 0.03387 at frame 514
Strange video pts step of -2959.10738 instead of 0.03387 at frame 516
Corrupted stream from the Network broadcaster.
Yes, it is clear now that this is a case of "garbage in, garbage out" and no software as good as it can be will ever be able to fix this.

I'm good with that.

Thanks a lot. :)

It works with frames rates too, but only if they’re reported correctly in the NALs. For H.264/H.265 that isn’t always the case.
That's interesting because I loaded the same video in Avidemux and it gave me this message:
top_gun_avidemux_message.png

However, VideoReDo didn't detect it when I tried QSF as shown in my post #8.

I guess this is a good example of "only if they’re reported correctly in the NALs"?

No this is just a sample point issue. In that dialog where you enable filters there is an option to increase the sample points and rescan. Do that until it finds this resolution change.

That dialog doesn’t scan the entire file, as that would be too slow, so it samples the file at X points, evenly spaced, looking for differences. 8 is default but increasing it to 12 or 14 shouldn't be a problem and could find missing changes.

I experimented by multiplying the number of samples by 2 until it found something.

With 512 samples, still nothing:

Finally, with 1024 samples, changes detected:
vrd_top_gun_qsf_1024.pngvrd_top_gun_qsf_1024_details.png

I chose the first one, then the second one, and saved the output files.
In both cases, I get a video with audio out of sync.

I just have to accept the fact that this source is very bad for recordings, and I will avoid it from now on.

On a positive note, it gave me the opportunity to try things out in VideoReDo.

I am extremely pleased with the support I received in this thread. :)(y)
Thanks to you, I figured out that the problem was with the source.

The Support team was great. Only 16 minutes after I sent them an email to request an extension of my trial period, they immediately accepted without any hesitation.

I am very happy to report that I just purchased a key for this wonderful program!
I am now an official user of VideoReDo. :D

Thanks again! :)
