Thanks!

Sorry, no we don´t. I have never used Bulk Mode, I simply have no use for it...

A..ok. Auto gain in bulk mode was requested some posts up. It basically normalize all the audio files and you can put an offset to it if you want.

Regarding chapters i will think of something...
Until then you can edit an text file and add the metadata to the output file.

The file should be formated like the one from attachment.
Addit to source files and then put in "More" at "Other Out", "map_chapters 1" Where 1 is the index of the source file, the metadata txt file that you add it.
It is convoluted, i know.

When batch transcoding, would it be possible to set "autogain" so every audio is normalized?

Thanx for considering !

Hi. Could you test the requested functionality and provide some feedback please?
Use the file from a couple of posts up.
Thanks.

Thanks, but your attachment has not been approved so far. Please correct me if I am wrong, but AFAIK FFmpeg uses a very different method to name chapter points than most othere methods I am aware of.

The FFmpeg chapter points are based on frame numbers while all other methods I am aware of are based on absolute time codes. This makes the FFmpeg method hard to use, the chapter point values will change whenever source and target fps are not identical, and for variable frame rate clips this is a total nightmare.

The other methods I am aware of use absolute time stamps for the chapters which are independent from the frame rate. Much easier to handle.

MkvToolNix can use either fixed chapters at a defined time distance, or it can use chapter files in either the OGM or the XML format. For my needs the simple OGM format is all I need.

So I think that you should not waste any time on implementing chapters in dmMediaConverter, use the existing implementations instead...

Hi!
This was in atachment:

;FFMETADATA1
[CHAPTER]
TIMEBASE=1/1000000000
START=0
END=1200000000
title=TitleXXX
[CHAPTER]
TIMEBASE=1/1000000000
START=1200000000
END=25500000000
title=title2
[CHAPTER]
TIMEBASE=1/1000000000
START=25500000000
END=60200000000
title=title3

So, it is time based in ffmpeg, no worry here.
As far as i can see ffmpeg does not support sub chapters...Chapters in chapters. Is something that is used in real world?
Another thing that does not make sense for me is end time of a chapter.
Can chapter be interlaced and not sequential?
Thx

Hi manolito.
I have implemented a basic chapter editor.
Please test it an tell me how it fits your workflow. Is it any good?
You can
1. Drop chapter information
2. Copy chapters from another file or the same file
3. Manual add chapters or import them from a source file and than edit them.
FFMPEG does not support sub-chapters.

Just redownload dmMediaConverter.exe from here:

Thank you.

Hi Marius,

spent some time this morning with your latest test version, a little rough at the edges, but much potential...

I did not test the first option "Drop Chapters Information". Which format does this option expect for the chacters?

The second option did not do much for my needs, too.

The last option "Manual Add Chapters" is probably the one I need. Scrolling through source video and select chapter points visually is very useful and works well. The feature I miss is a very simple option "Create Chapter every XX minutes". Should be easy to add such an option.


Otherwise there are some stability issues, it was easy to crash the software by clicking an option which was not supported in this mode. But the worst what happened was that the software shut itself down, no corrupted HDD or worse.

Also a few times after the conversion had finished, the software shut itself down. But the conversion result was fine, so I am not sure if this new behavior is intentional...

One cosmetic thing I noticed was an incomplete chapter result in MediaInfo. The chapter times were displayed, but the fields for the chapter numbers were empty. No big deal.


I believe this chapters feature will be very useful, thanks again.

Cheers
manolito

Hi! Thank you for testing this!
Drop means that ffmpeg will not do the default behavior and copy chapter information from the first source file, but discard all chapters, basically output file will have no chapters information.
Please redownload from the same source and test it again, if this stability of the software is ok now.
I will think of something in the following weeks about adding this option to add chapters every X seconds.
There is no field in ffmpeg regarding chapter number, it is done automatically by ffmoeg.
Thanks and waiting four your feedback.

Thanks for the clarification, I completely misinterpreted the meaning of this option. When I saw the word "Drop" I saw it as "Drag and Drop" and looked for information how to take chapter information from a separate file and drop it on the "Drop" field. Sorry for my misinterpretation.

Otherwise the previous instability has been fixed, thanks. I believe that the last "Manual Add Chapters" could be simplified a little bit. IMO chapter end points should be omitted, a chapter always ends when the next chapter begins or EOF is reached. And the "Chapter Name" field could be populated automatically with something like "Chapter 01" where the chapter number is generated automatically.

Hi,

sorry, mail notification does not work, so I did see the post just now...
I will check and get back

Thanx!

Hi Manolito! :-)
I will not remove END times column but it is not required to be completed. The app will do it automatically.
I have added the option to auto add chapter names.
If you insert new chapters, since the list is sorted, chapter names could become mangled. So right click on the list and choose "Remove chapter names" and then choose "Auto complete chapter names" and all will be in proper order.
Also, there you will find two new functions.
The beauty of it is that all of this can be use in Bulk mode!
Please, test it and provide me some much appreciated feedback.
Thank you!
Just redownload the exe file.

Hi Marius,

so far I only had time for a couple of test conversions using my preferred mode of one chapter every 300 or 360 seconds (every 5 or 6 minutes), and this worked perfectly for a couple of source files. Output was either MKV or MP4, no problems with either of these formats.

I believe that this version is a winner, IMO ready for prime time. Maybe others will find some issues, but for me it is time to remove MkvToolNix from my standard conversion chain.


Thank you so much from a happy customer.

I took a DVD out of the shelf with a few audiotracks on them, commentary being very low on volume and AC3 Formats. Good candidate for a test. So tossed it into batch mode window.

All went well. Scanning the Audio Tracks takes a little, after that the job is added to the qeue and is good to go and finishes as expected:


I was wondering about the speed, it was roughly 9x realtime on a 1950 Threaripper with a SATA SSD - with the video simply copied and three AC3 Audio Streams being converted to AAC. This could be faster I guess, but if any, thats an ffmpeg issue and at the end it doesn´t matter a lot. Its working

Thanx for this great addition !! It makes batch encoding even more useful on your nice tool

I just got a new GEN30 Nvidia Card and was toying with the NVENC Encoders. I am used to NVENCC user interfaces and options - not sure about the ffmpeg options, which I beleive are different syntax and settings. Could you take a look at the dropdown options for nvenc encoding ? AFAIK the options listed are outdated.

Thanx!

I did prepare a preset for batch encoding with x264 set to Q=23. While encoding, the status line shows "Q=28". Some mixup with my ffmpeg versions?

Hi. I can not see the picture...attachment pending approval ... since this morning.

I think it is the difference between quantization and CRF

Its only a screenshot of two audiotracks, one being louder than the other
bottom Line: Auto gain of multiple channels in batch mode works
