Thanks so much for that, I initially had no luck with your 3.4.0.01 Beta, the same Unhandled exception error occurred again but then I noticed a previously muxed file appeared in the Multiplex screen for some strange reason, so I had a look in my set Target folder & came across a PE_open & SWF text files along with previously muxed files that I had created with earlier versions of your program, I deleted those & would you believe it, the program works perfectly fine now, I tried v3.3.7 & the latest v3.4.0 also the v3.4.0.01 Beta you sent via PM without any issues at all, I'm so terribly sorry to have troubled you about this, thanks for being so gracious & very patient with a noobie like me, not quite sure why it mattered that I had previously muxed files in the Target folder made with earlier versions of your program that caused v3.3.7 onwards to falter & not work at all, anyway thanks so much again for your time.

I'm glad it's working now.
Have fun with it.

Okay. I checked the vob file with MediaInfo:

Width : 720 pixels
Height : 576 pixels
Display aspect ratio : 4:3

720 / 1,33 makes a height of 540. No problem!

>> Video preview for unfiltered HDR/HLG/DV content. (Display can remain blocked with older CPU's).
The new pale information window appears.
The HDR to SDR preview looks like HDR because it has a huge color range.
> I cannot confirm this; corrected HDR sources (either HDR to SDR or with LUTs) are displayed correctly in color.

Example with LUT

I thought a 10 to 8 bit reduction (HDR to SDR) would look like the pale example.

>> When I use a HDR source with PQ_to_BT709_v1.cube or an other HDR LUT and switch encoder to none hevc and click preview, I get an error:
> Should not happen, because the LUT's transformation is independent from the encoder.
Have to investigate on this.

This might help:
When I load PQ_to_BT709_v1.cube, the encoder change automatically to x265 (hevc).
When I load BT601_PAL_to_BT709.cube, the encoder change automatically to x264 (avc).

HDR video encoding with h264_amf and hevc_amf gives an error message when the profile is set to auto:

[vost#0:0/h264_amf @ 00000198194df5c0] Error while opening encoder - maybe incorrect parameters such as bit_rate, rate, width or height.

[vost#0:0/hevc_amf @ 000001dc37fa87c0] Error while opening encoder - maybe incorrect parameters such as bit_rate, rate, width or height.

No problems with profile main or main 10.
My hardware does not support av1-amd.
x264 (avc) and x265 (hevc) works fine with auto for all encoder settings.

When set to auto, doesn't the encoder select the appropriate setting itself?

Btw, my old Nvidia Kepler GPU does not support HDR.

How about the idea to add an info textbox for the different subtitel typs you can convert to?

Is there a reason why chapters and attachments get ignored for added files in multiplex?

How about the idea to add a "Remove streams" button between "Swap streams" and "Attachements" on the multiplex page to clear the table from the selected streams? No fles will be deleted.
Maybe a combined button is possible. "Swap/Remove streams" will remove when there is no Idx change.

---

On the Multiplex page, you use the green text line
Muxed Chapters: E (Textbox: Embedded chapters are muxed)
and
Muxed Chapters: C (Textbox: Created chapters are muxed)

How about a simple:
Mux embedded chapters
and
Mux created chapters

Would it be possible to add a "Start at second" option in the video encoding Sample window?
To be able to define start and duration of the sample.
If you want to compare encoder settings/quality based on samples, you can then skip the intro and select specific video parts whitch could be found using a time code in the preview like for cut.
Values for start and duration should remain till you close the page.

Where? In the convert subtitle section, all options are already entered in the convert to box.

Yes, because chapters and attachments need a special way of muxing, not like the other streams with streamcopy.

I don't want to change that; it's clear enough, and there's a lot of background code attached to it.

Video encoding sample processing:
Is there a reason why To batch and Stay open is hiding when you check Sample?

I would expect that the target file name get a _sample extension when you check Sample.
Currently, you need to change the encoder after you checked Sample for that.

[ProWo]

Video encoding sample processing:

With sample encoding, I assume that this is done immediately and therefore batch is unnecessary.
Stay open is not necessary, as the current screen remains open after encoding so that further samples can be encoded.

I would expect that the target file name get a _sample extension when you check Sample.
Currently, you need to change the encoder after you checked Sample for that.

This is a bug that has already been fixed.
If you want, I can send you the current version via PM for testing.

Bug with target file name extension _sample has been fixed.

Good idea to check propper values for "Start at" and "Duration" also for short videos. Standard is 180/60.

Start and duration values ​​are retained until the page is closed. Good.

The processed samples match the values ​​used. Good.

A small thing! "Progressive encoding" disappears "after" the click on OK, and not before!

How about adding the current timecode to the video preview to identify the start time of certain scenes?

The Multiplex page only show "Muxed Chapters:"
The E or C is missing.

Bug. Will be fixed.

That's superfluous, I think.
The sample function is not frame accurate, but starts with the keyframe before the specified start second. So it wouldn't be accurate anyway.

Okay!

But the intention is not the accuracy of the start/end time of the samples themselves, they are more likely to be deleted afterwards because they only contain video.
It is to use the apps preview (back/forward) to find the approximate start time of a certain scene (with lot of movement/panning or very light/dark shots) that you want to use as a sample to proof/compare encoder settings/quality.
So you don't need a separate video player to find this time codes.

Another objection:
PTS is displayed in the format HH:MM:SS, which means you would have to convert the displayed time into seconds.
All very time-consuming.

EDIT:
I will insert the timestamps in the video preview.

EDIT2:

Thank you for inserting the timestamps in the video preview. Other players also use the format HH:MM:SS.

No problems found at Video encoding -> Sample. Great!

The new Multiplex -> Clear streams button is working as expected. Thank you!

The new Sample -> "Sart at" also works in Multiplex.

But there is a bug when you open the Multiplex page. The Attachments button is always visible when you open the page. It does'nt matter of the source or the container. It will disappear if you change the container to none mkv.

Missing E or C after "Muxed Chapters:", still need to be fixed.

Maybe "Change target file name" can be shorten to "Change". Because the button text is clear enough.

Multiplex page:

The thing is that you can see the Attachments button disappear when the source has attachments and the container is not mkv.

Set/change for "Target file name" is okay.
Did you know that you can also change the directory for that file?
But all get reset after the Multiplex or when you select Simple remux or Sample after you change name and/or directory.
But you can select Sample and change name and directory afterwards.
I'm not sure if it makes sense to keep the changes till you close the Multiplex page!

When I would like to add an audio stream lets say from the english version of a movie to the italian movie, I have to find the audio delay manually.
Can you force ffplay to use a delay for a preview without muxing?

[ProWo]

The thing is that you can see the Attachments button disappear when the source has attachments and the container is not mkv.

This should be the case because attachments can only be muxed in mkv.

Can you force ffplay to use a delay for a preview without muxing?

This can be done much better with other programs, such as VLC player.

[Findu]

>> The thing is that you can see the Attachments button disappear when the source has attachments and the container is not mkv.

Yes, I know.
I mean, if the source contains attachments and the container isn't in MKV format, and you open the multiplex page, you'll see the "Attachments" button for half a second before it disappears.

I never see it with other versions.
You might see it if your laptop is in power saving mode and reducing CPU performance.
