Question

Bluray compression issues, glitches & artefacts

Hi, I have been authoring a blu-ray for the master of my film and the quality is very low. There are hundreds of very detailed paintings and drawings and there are glitches and digital artefacts that appear on the blu-ray in nearly every image. I exported both H264 Blu-Ray and MPEG Blu-Ray from premiere at maximum render quality and authored in Encore. The H264 version is marginally better but it's definitely not good enough to be screened.

I exported a regular H264 to compare and the quality is much better. I don't know if it's the H264 Blu-Ray codec that is causing the issue or if the problems come from Encore.

Can anyone please help? This is urgent.

I'm a registered user of x264 pro and unfortunately after an upgrade of my system, the 3am Studios licensing server is not available anymore. So I had to look for alternatives. The recommended tmpgEnc plug-in seems to be a solid solution, but I'm missing the picture profiles of x264pro (I always used 'retain grain'). I have no clue of which advanced settings have to be changed in pegasys' plug-in for realizing the same results.

I've found another plug-in, open source and very powerful, with full x264 (others also) support. Voukoder ( https://www.voukoder.org/ ) It seems to be a very good successor for my good old x264 pro. What do you folks think about it?

Thanks for the encoder tip - interesting it may also do ProRes for me as well - which Adobe cannot unless I change to Windows 10, which means building a new NLE and right now I have not got the money to do this as £5k is a large chunk of change plus needing time to learn W10 and in all honesty I just don't want to be forced into an OS I do not like. So greatly appreciate the tip.

It's a shame Edward has gone dark, although as soon as his copy protection was hacked he was screwed at that point because so many people seem to think that using hacked software is okay, is somehow not stealing or victimless - it isn't, it is still theft and it kills people's businesses and destroys livelihoods.

You're right, it would have been nice if he had informed his customers and gave them an option of using the software without licensing server back-check. I used the software for years and was very pleased with it, but it was no low-cost software product. These are the cases where you think about better buying software of the reputed manufacturers...sadly!

Okay - things are not what they seem I suspect.

We need more information here though:

1 - What is the source of the material used?

2 - What is it's resolution (in DPI if stills)

3 - What is the codec of your source footage, it's resolution & frame rate?

4 - What are your target settings?

I have a sneaking suspicion that you have got something badly wrong, as Blu-ray authoring is NOT something you can do from presets & clicking a mouse. You really do need to know what you are doing or else you can easily get exactly these issues - it is all about the asset preparation.

Hi everyone, thanks for the replies. I tried many different export settings yesterday and finally fixed the issues by doing the following:

Importing the pro-res HQ export back in premiere

Applying "Flicker removal" to the prores in premiere

Exporting a MGPEG 2 bluray at 40mbps/s

Creating a .iso file in Encore

Authoring disks from .iso

For some reason, the previous MPEG 2 bluray and H264 bluray exports had enormous amounts of aliasing (there was none in the pro-res) and the flicker removal option is the only thing that seems to have helped.

Another question - I exported the bluray in PAL 25fps as the film master is in 25fps. The film is going to be screened worldwide and I have concerns about NTSC regions, especially in the US. Will they be able to play a Blu-Ray at 25fps? It seems as if some blu-ray players handle both and some don't, but can anyone advise please?

If not, what is the best workflow for creating a NTSC - 24fps bluray from a 25fps master?

Thanks in advance!

All UK players will play NTSC discs, unfortunately most US players will not play PAL discs. The Blurays I make I shoot in 25i and then use a standards converter to make the 29.97i version. The best converters, like the Snell Alchemist, are very expensive and even sending the work out to a post house can cost £1000+. I have a teranex device and if you would like to Dropbox a sample of your film I would be happy to show you the quality it produces.

I don't know if it's the H264 Blu-Ray codec that is causing the issue or if the problems come from Encore.

When it comes to fine details the H.264 Blu-ray encoder can be really bad. Try the TMPGEnc Movie Plug-in AVC for Premiere Pro and export directly from the timeline using one of the Blu-ray presets and use a decent bit rate. The TMPGenc AVC plu-in is superiour to the standard H.264 Blu-ray exporter.

As Stan Jones writes, post a screen shot of your export settings since a mismatch/wrong settings can be as problematic.

And even better than that encoder is the x264 Pro plugin.

Sadly the website is down at the moment which is a real shame as it is seriously good.

neil wilkes, have you compared the two?

I have both and have found that x.264 Pro has more macro blocking artefacts than the TMPGenc AVC Plug-in. When going forward frame by frame those issues can be discovered easily with x.264 Pro. So no, x264 is not the better one.

x.264 Pro has not worked properly since CC2015, lot´s of Low-level errors, missing chapters at export, no updates of the plug-in, etc. The homepage is down and the product seems to be EOL. I did send support mails that never got answers. It seem that x.264 Pro is history since it has vanished. I hope Edward is ok and well.

Better encoding results, it works with CC2019, aviable to buy, being updated makes TMPGenc AVC Plug-in the winner.

"Maximum render quality" is not what you think. What is the bitrate you used?

Post a screenshot of your export settings.
