The VideoLAN Forums

I've done a bit of searching around for this, and haven't found anything similar, so either I am doing something wrong, repeatedly, or other's don't mind/care.

Using latest version of VLC, on Windows, with no special settings or other weird uses. This problem is not version specific, I've noticed it happening for a while. If memory serves me right, this did not used to happen, once upon a time, but my memory is hazy.

I am using SRT subtitles, and noticed a couple odd behaviours.

When a subtitle entry has 3 lines, they will sometimes get collapsed into 2 lines. Not sure why, or what the criteria might be. It's not a huge deal, but often a separate line means it is a separate piece of dialogue, spoken by a different character. So this is a problem, but the actual problem is that when this collapsing happens on a subtitle that is in italics, there will be no space inserted between the two collapsed lines, whereas when there is no markup, there is a space. This makes the subtitles look like a real mistake.

The second problem is alignment. I have the subtitles positioned at "bottom", which is the default setting. Create a simple SRT file with one entry consisting of 3 identical lines, when displayed (assuming they don't get collapsed), the first 2 will be perfectly aligned vertically, but the last line will be noticeably offset to the right a few pixels.

Mostly, I'd just like to know what I am doing or not doing that is causing the concatenating of that 3rd line sometimes.

Please share a sample.

Ok, I've been doing some more checking on this, it seems the "line collapsing" thing is something Handbrake might be doing when encoding the mkv file. I'm supplying an .srt file as a subtitles input. When I extract the subtitle stream from the mkv, the lines are actually collapsed, vs the original source where they are as intended. I will just have to mux in the subtitles afterwards using other tools that will not mangle the lines.

However, this does not explain the removal of a space.

Here is what a "collapsed" subtitle entry looks like:
There is a space between the two italics markup tags, but during playback no space is apparent between "darling" and "all".

That should be registered in the bug tracker.

Code: Select all

You should create a new ticket on the VLC Trac with your sample file and the link to this thread.
