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

The preview stay within the screen bounds for the problematic 720 x 576 VOB, 640 x 480 MPG and the 1080 x 1920 mobile video. Excelent!

NEW: I get an error when I preview a 6 h video. The preview is normal when I click Next at the error window but starts at 20 seconds.
Seams to be a problem with the 5% calculation for the preview start.

Exact. The max value is currently 1000 seconds. It will be increased.

I hope in next release i can change just 'height' and keep aspect ratio.

Will be done.

> The only limit atm is that HDR to SDR tone mapping cannot be previewed; however, if you use LUTs for this (e.g. PQ_to_BT709_v1.cube), the preview is possible.
But I am working on a solution.

You are right. When I use LUTs, the preview of HRD content is working, including other filters.

If you frequently work with HDR sources, it can be helpful to have the LUT automatically activated when the app detects HDR files upon opening. An entry in the settings could therefore point to your preferred .cube file. If one is specified, it will be used. If none is specified, no LUT will be loaded, like for standard files.
If the LUT is not suitable for the current film type, you can change it under "Filters & More" or switch to HDR filters.

I think that you do not need HDR output for the other previews like cut, crop or chapters.

[ProWo]

I think that you do not need HDR output for the other previews like cut, crop or chapters.

FFplay is a simple player and cannot play HDR content correctly.
But because I want to stay with this player, I have solved this as follows:
Any content can now be previewed.
For HDR/HLG/Dolby vision without filter/LUT's, a message indicates incorrect color reproduction.
HDR to SDR with tonemapping can now be previewed correctly.
Will release v3.4.0 soon.

@ProWo I was just wondering why I might be getting these Unhandled exception errors when I go through the initial start up of adding the ffmpeg bin folder & target folder, when the Unhandled exception error pops up & I press continue, it goes straight to the Multiplex screen & the "This is the first launch. Welcome" dialog box screen remains for some strange reason, I've tried using the latest ffmpeg 7.1.1 Static & Shared builds here https://forum.videohelp.com/threads/414767-ffmpeg-7-0-1-and-Windows-7#post2769089 which is where you had suggested I try as Windows 7 no longer supports Static or Shared builds officially only Essentials builds which is problematic with your program as we had discovered previously when certain functions didn't work properly, I've also tried the latest v3.3.9.05 Beta with the same Unhandled exception error, not quite sure what has possibly changed since I last used one of your Betas from around September or October of last year.

1) Delete the file portable.config (in the folder with clever-FFmpeg-GUI.exe).
2) Restart clever FFmpeg GUI.exe and follow the instructions (The programm ask for the bin folder with ffmpeg.exe, ffprobe.exe, and ffplay.exe in).

Yeah I've tried that unsuccessfully, this is the error with v3.3.9.05 Beta, it mentions "Cannot start process because a file name has not been provided."

[Attachment 86351 - Click to enlarge]

I wish I held on to that previous Beta of yours, don't quite remember the version I had from around September or October as it was working fine with the non official FFmpeg builds for Windows 7, I guess it may have been something in your code that you have changed since then that will now no longer work with Windows 7.

I've tried to use the program but it appears it won't let me when I try to add a source file, another Unhandled exception error pops up with this message "Index was outside the bounds of array."

Do you have this files in your ffmpeg bin folder?

You are the first to report such a problem.

Yes those files are in the FFmpeg bin folder, is it possibly something that was changed in your code that Windows 7 no longer accepts, what exactly do these error messages "Cannot start process because a file name has not been provided." & "Index was outside the bounds of array." mean?

Those builds should be fine as I tried the one listed here https://forum.videohelp.com/threads/414767-ffmpeg-7-0-1-and-Windows-7#post2749956, the FFmpeg 7.1 Static 64bit build back in October 2024 & there were no issues with your program, it must be something that was changed since then that is affecting Windows 7 usage, I tried the Static build just now with only the 3 files in the bin folder, no such luck unfortunately the Unhandled exception error still pops up, I click continue & then it brings me to the Multiplex screen, it's a shame I deleted that October Beta release as at least I could've still used your program, do you know what the "Label 4" in the bottom left corner of the Multiplex screen means?

[Attachment 86356 - Click to enlarge]

[ProWo]

do you know what the "Label 4" in the bottom left corner of the Multiplex screen means?

Label4 is the label name, without info, because the program isn't fully working.
As i said, try to add the .exe suffix to the 3 files.
If this not works, retry with the last full release v3.3.9.

Yeah I just tried that but it returns a "files missing!" error, I don't think the .exe suffix is necessary in this case, those 3 files have always been simply

Thanks so much for that, the official v3.3.0 version actually works fine with FFmpeg 7.1 Static build, would you be able to have v3.3.1 which was your official October 2024 release, what could be the issue then with your more recent builds, it's definitely a head scratcher?

Thanks for that, I didn't realise you kept an archive of previous versions, I can confirm v3.3.0 to v3.3.6 has no such issues, something changed with v3.3.7 to v3.4.0 as I get that Unhandled exception error message that I had attached earlier, the issue is present from your January 2025 releases right up to the latest Official v3.4.0 release.

[oniiz86]

@ProWo I was wondering if these changes mentioned in v3.3.7, Added "Check in reading BT_open.txt if the file exists." & "Many little cosmetics and code improvements.", perhaps the code improvements that were made has made your program with Windows 7 no longer compatible after v3.3.6? I just tried the latest FFmpeg 7.1.1 Static 64 Bit build with v3.3.6 & it works absolutely fine, so those non-official Windows 7 FFmpeg 7.1/7.1.1 builds appear to be okay, just no such luck with v3.3.7 onwards.

With 3.3.7 I have added full portability.
That gives me a doubt. Did you extract all files from the downloaded zip archive or just the exe?
I think you are missing the two files:
PortableSettingsProvider.dll and
clever FFmpeg GUI.exe.config

Download the latest release v3.4.0 again and
Extract all files to the same folder where you want.
Then start clever FFmpeg GUI.exe.

I don't believe that is the case as v3.3.6 & v3.3.7 both share the exact same files, both these files PortableSettingsProvider.dll and

When you abort the encoding of a video sample, the partly processed file remains and does not get deleted.

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.

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.

> Video preview for unfiltered HDR/HLG/DV content. (Display can remain blocked with older CPU's).

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.

This information isn't visible, its used only for the encoding process.

Bug, will be fixed.

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.
