Srt subtitle extracted from EIA 608/708 still retain Closed Captioning format with the "Fontface monospace" stuff. Normal srt subtitles don't have that. During playback, the subtitle stays in the upper left corner and is not adjustable like a normal srt sub. Can you fix it so it behaves like a true srt subtitle? Thanks.

The subtitles are correctly extracted.
If you do not like the formatting, remove it in Subtitle edit.

Files with two video streams:

The video encoding and cup previews always show stream 1, even if stream 0 is selected.

When you cut/join such a file, both streams are preserved in the cuts/joins, which makes sense.

The previews in cut search cut points & preview, chapters video and various crop also show only stream 1.

What about all the "Various" options like crop when the two streams have different resolutions?
Metadata crop only works for stream 0.
Metadata rotate for both.
Maybe a text on the Various page could inform about the limitations of files with multiple video streams!

Videos with several video tracks are very rare because they are actually unmanageable, unless it is the same content but from different angles, for example.
If the content is different, how should the audio and subtitle tracks be handled?
I will still work on handling these video tracks correctly.

@ ProWo
NEW ffmpeg version 7.1.1
Would it make sense to offer an automatic install/update (W10/11 64 bit only) for ffmpeg?

I won't do that because there are too many different builds and I don't want to favor just one provider.

[ProWo]

Just an error message at start of the app when the ffmpeg path does not match the entry in portable.config.
It's not a big problem because you can still adjust the path in the app.

To do this, the user must intentionally move the ffmpeg folder. But I will add an additional check.

I don't have such files either!
For testing purposes, I muxed the second stream in grayscale.

Some older movies have cutted scenes. These cuts do not have the national dubbing from the past.
In the DVD menu, you can choose between the short national version and the extended version including the cut parts in original video, original audio, and subtitles.
The DVD may use chapters to skip that scenes for the short version. However, this only requires one video stream.

But I had an animated movie in which all the scenes with signs or text were in English, German, and Italian.
I'm not sure how this DVD was structured. Perhaps separate streams or even chapters for that short scenes.

You are right. I'll restore this possibility.

Just a question, not a requirement. Is not possible to set CRF or variable bitrate in H265-NVenc enconding?

[ProWo]

Just a question, not a requirement. Is not possible to set CRF or variable bitrate in H265-NVenc enconding?

I intentionally stick with CRF because that is the setting recommended by the FFmpeg developers.
In addition, CRF does not encode everything with the same bitrate, as is wrongly assumed, but the bitrate is automatically adapted to the content by the encoder itself.
If you watch the FFmpeg line during encoding, you can see this.

Hello Prowo.
Your program is wonderful and is being enriched with new functions thanks to the suggestions of users that you listen to very kindly.
For me many functions are unknown as I am a neophyte.
I kindly ask you if in the future you plan to make a tutorial on all the functions for beginners like me.

[superballs69]

Hello,
I think it would be nice if it had CBR options for the x264 avc encoder. I record my videos in CBR.
Also, the program uses 100% of the CPU. Would be nice if there was a way to limit CPU usage.
Other than that, pretty good. I spent a couple hours trying to find a program that could convert I444 to I420 with quite literally zero meaningful results, because DaVinci can't process I444 video. Then I found this at last. Very helpful.

I'm glad you like it.
The program has a lot of functions, most of which are self-explanatory. I have also included many tooltips to help you.
Probably the most important thing is that, unlike most others, my program handles the different streams separately.
For example, you can only change the video stream and leave the audio and subtitles as they are.
I myself use the program daily to reduce the file size, i.e. I recode the video stream and then mux the remaining streams.
To come back to your question, creating a complete tutorial with all the functions is honestly too much work for me.
But if you have any questions, ask them here and I will answer them.

New findings:

If you cut a source with more than one video stream, “Use Virtualdub for KF search” is grayed out.

When rotating 90 degrees, some 1280x720 videos don't maintain their aspect ratio in the preview window. The video will be fully expanded in the 16:9 window, as the preview window does not use portrait itself. Other image/preview sizes and the encoding seem to be fine. The metadata seams to be okay!

When you crop and resize a video, it would be nice to use the new crop DAR for resizing. Could the checkbox for "source DAR is retained" switch to "crop DAR is retained" after you set values for cropping?
It should switch back when you click Cancel Crops.

I am not abel to enter values for Various -> Crop any longer.

Can meatdata crop not be set for each video stream?

Is "Keyframe cut" the only option?

If you cut a source with more than one video stream, “Use Virtualdub for KF search” is grayed out.

This is ok so, because Virtualdub has no possibility to select the videostream.

When rotating 90 degrees, some 1280x720 videos don't maintain their aspect ratio in the preview window. The video will be fully expanded in the 16:9 window, as the preview window does not use portrait itself. Other image/preview sizes and the encoding seem to be fine. The metadata seams to be okay!

Tested with many 1280x720, 16:9 videos, I can't reproduce that here. Please post a pic.

You can change the values with the controls. This way is impossible to insert wrong values.

No, for h264 and hevc only

Is "Keyframe cut" the only option?

Yes at the moment; in my beta I'm testing frame accurate cutting for h264 and hevc.

I can not cut MPG files any longer: Error

This happens with videos with videostream index 1 instead of 0.

I can't drag and drop when the program keeps minimizing/disappearing to the background of a bigger program. It would be so nice to have a "stay on top" capability.

CRB encoding is an inefficient encoding because the same bit rate is always used regardless of the content.
For this reason, I do not use it.
To get around the 100% cpu problem, you could use an encoder that uses hardware support, e.g. h264_qsv for newer Intel platforms.
Other encoders with hardware support are h264_amf (AMD hardware) or h264_nvenc (Nvidia hardware).
Experiment for yourself.

The problematic videos now maintain the aspect ratio when the preview is rotated 90 degrees.
However, the previous control of the height of the preview window is bypassed by rotating it 90 degrees. Because the rotated preview window is now too large and parts of the W11 menu bar covers it.
