Ah, that was probably the problem, then. You effectively had two audio steams, one in MPA (that came with the video) and one in AC3 (in the separate file), and the authoring program was probably tryin ...

So when you render the audio and video separately, the file sizes match the expected sizes?

What was your compressor rendering in your first attempt? A single MPEG-2 file with embedded AC3 audio? ...

As you can check by doing the maths:

80 min. x 60 = 4800 seconds

4800 sec. x 320 kb/s = 1536000 kb = 192 MB (183 MiB)
4800 sec. x 7100 kb/s = 34080000 kb = 4.26 GB (3.967 GiB)

Total: 4.452 G ...

When you say it jumps and freezes, which of the following are you talking about:

a) Playing back the VIDEO_TS folder on a computer.
b) Playing back the DVD on a computer.
c) Playing back the DVD ...

The clicks in the audio shouldn't have anything to do with the bitrate. They are caused either by problems in the source audio, problems during audio compression or problems during audio decompression ...

Of course. You are supporting them. Wink

In case you don't know, it was precisely due to Sonic's superior software that I started using TMPGEnc and it was precisely because of Sonic's superior suppor ...

For some reason I didn't see this message until today. Sorry for the delay, but here goes:

Do you make these for sale (meaning you need a format that's easy to distribute) or for exhibitions where you have more control over the format and playback equipment?

By the way, I had a similar ...

Without much in the way of useful results, though. Smile I've tried other decoders and the same thing happens, although the exact banding pattern varies slightly (which might indicate that the issue is i ...

I've used your first frame to make a few tests, and I found that there is no change in the banding even when creating a HP@HL 11-bit MPEG-2 file, which is odd. At 11 bits per DC coefficient there shou ...

The size (in bytes) of the original files has no influence on quality. Regardless of their format, the frames always need to be decoded (in other words, converted into uncompressed bitmaps) before any ...

It's odd that the "CG" matrix worked better than the "MPEG Standard". It should be significantly better at preserving hard edges, but worse at smooth colour transitions. Then again ...
