parts stacking and multi-version movies at the same time

[joshinils 13]

I have a TV-recording of Schindler's list and a two-part two-DVD version.

Can I have both as a grouped version visible?

Currently, I have a (sub-)folder "1993" with the following sub-folders:

├── Schindlers Liste_1993 - DVD
│   ├── Schindlers Liste_1993 - DVD - part1-320-10.bif
│   ├── Schindlers Liste_1993 - DVD - part1.mp4
│   └── Schindlers Liste_1993 - DVD - part2.mp4
├── Schindlers Liste_1993 - RTL II
│   ├── Schindlers Liste_1993 - RTL II-320-10.bif
│   └── Schindlers Liste_1993 - RTL II.mp4

However, when the auto-grouping add-on puts these together, I can only select the RTL version, or the part1, there never is a part2.

I'd also like for the version to include the whole part after the dash, i.e. `RTL II` and `DVD - part1`, now it shows only `Schindlers Liste` and `part1`.
Which may be confusing for someone who can not see the filenames at the bottom.

Hi.  Why not combine the two DVD parts into a single file?

There was a black border which I removed with handbrake, the border was different on the two parts.

I never experimented with combining parts like this. I don't know what will happen to the video, audio and subtitle streams when combining with ffmpeg, and if I can do it without having to re-encode them. What happens to the different resolution because of the differently sized black bars?

Redo the removal setting the cropping manually to be the same for bath parts.  Use MKVToolNix to join them - easy to do, no transcoding, and it verifies that the two parts match before going ahead.

That would involve having the DVD, which I don't. And would also mean re-doing the handbrake compression, i.e. re-muxing the video and re-normalizing the audio with ffmpeg-normalize.

I have to look at that, thanks. Maybe I will re-do one of the parts, adding a matching black border.
I guess simply concatenating them when the resolution is different will not work.
Swapping to mkv container was on my todo-list anyway (because of Blu-ray subtitles), so any new media ingested is in MKV nowadays.

The ability to use these two features together should be a little improved in the upcoming 4.8 server release, but we'd still always suggest joining multi-part files whenever possible.

Yeah I get why, autoplay for parts was not a thing last time I checked.

Are there reasons I don't know of for when parts-merging is not possible?

 

For example, I have to re-encode the second part, avidemux shows there is no I-frame after the 1 second of black in the beginning, the tv recording shows there is no pause, so I want to remove it. The first part has an I-frame there, so I was able to remove the end without re-encoding.

It looked like mkvmerge lost the metadata when appending the parts, and display-aspect-ratio and/or pixel aspect-ratio, is that normal? Can I keep that somehow?

I think O can set the metadata title with vlc of ffmpeg, but ffmpeg means copying the file, why idk.

Well if they were different formats then then you'd have to convert at least one first. If you're handy enough, no reasons I can think of.
