clever FFmpeg-GUI, small FFmpeg UI, fully portable, no installation.

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.

>> When I use a 720x576 DVD rip and click retain DAR, the resolution change to 720x540. The source DAR is given as 1,33.
Common 16:9 resolution changes work normal.
> With DVD resolutions, there is no universal concept, because you don't know what the user's goal is.
If he resizes a DVD source, then manual intervention is required anyway.

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

HDR to SDR

Pale

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).

3.4.0 Feedback 2, more HDR testing

When you click No at this dialog, Stay open does not reappear.

When you see this dialog, you will see two instances of the app and the missing encoder settings.

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.

3.4.0 Feedback 3

Is it possible to reactivate the audio output during the preview?
I would especially need it for cut.

The preview in Various -> Crop does not work any longer.

3.4.0.01 Feedback

Cut help screen disappears when opening the Cut page. Is fixed.

Aborting of a video sample does not delete partly processed file. Is fixed.

Preview cause error with HDR source plus LUT after switch encoder to none hevc. Is fixed.

Stay open and Main Page botton does not reappear when encoding or encoding a sample in the same case from above. Is fixed.

Stay open does not reappear when you click No at HDR10 dialog. Is fixed.

Mastering display metadata dialog, cause two instances of the app and missing encoder settings. Is fixed.

The preview in Various -> Crop does not work any longer. Is fixed.

h264_amf and hevc_amf HDR encoding cause error message with profile auto. Is fixed, because auto has been removed.

Reactivate the audio output during the preview. Is working. Thank you.

NEW: When using LUT, the Color space option disapper from the page. Is definitely intentional!


As always, thank you for all your fixes

Newest beta (v3.4.0.01), online now.
(Changelog will follow in the next full release).

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.
