Keep Subtitles When Cutting

[Mr. Fanservice]

What are some frame-by-frame video cutters that support and keep subtitles after cutting, and can encode them to lossless video codecs?

As far as I know, all but one form of subtitling must be edited separately from the video and audio using a subtitle editor. EIA-608 closed captioning (used in North America and (I think) Korea) is the one exception I am aware of, and most video editing software strips them when exporting the edited video. The only video editors I have used that preserve them are VideoReDo (no longer available for sale) and TS-Doctor (only for editing video and audio in a TS container).

Can LosslessCut encode videos to lossless formats?

Can LosslessCut encode videos to lossless formats?

The version I have installed is over a year old, but as far as I can see,
it doesn't encode at all, it copies the stream to compatible containers, with the bonus of
having a "smart" capability for the start and end when the source cut point is not on an "I" frame

[Mr. Fanservice]

Can mpv and ffmpeg do it, then? How do you get a video preview for the latter while doing it?

I don't know, I'm not familiar with mpv.
Can't you just use vdub2? See the in and out cut points, set video compression to a lossless format (eg. ffv1) and encode

You're talking about soft subs? I don't think it will work but you can try.
Have you thought about burning in the subs? Then you can edit easily

I mean embedded subtitles.

[davexnet]

Strictly speaking the subtitles can be soft or hard embedded. Which type is it?

They are pgs files, not hardcoded, and not on forced display.

If by "embedded subs" you mean a separate subtitle stream stored in the same container file with the audio and video (for example, an mp4 or mkv), you still need to edit those subtitles separately with a subtitle editor to match the clips that you export.

[Mr. Fanservice]

Does your program work for pgs subtitles? Can it cut videos frame by frame? Does it have a video preview?

There are no video editors that can cut PGS subtitles that I know of.

I haven't tried cutting PGS subs myself but I seem to remember a thread that said it can be done with Subtitle Edit. However, I think subtitles have to be demultiplexed first.

You can use clever FFmpeg-GUI for cutting and preserve all embedded subtitles, but on keyframes only.
The cut is done with streamcopy, so no reencode is done.

After cutting, you can of course re-encode as you wish.

Do I get a preview while I'm cutting?

You can preview while searching the keyframes.
You can also watch the video in any player and make a note of the desired cut times.
clever FFmpeg-GUI then searches for the closest keyframes and cuts to them.
The cut is fast because it is done with streamcopy.

Does it support precise cutting? I'm fine with lossy cutting.

[ProWo]

Accurate cutting and lossless cutting are two different things. As I said before, clever FFmpeg-GUI can cut on keyframes lossless that it runs as streamcopy.
But something else.
You ask and ask and ask, I won't answer you anymore unless you ask for a well-defined problem.

All right, how about this? I originally wanted to burn in pgs subtitles, but I realized that .ass is better so I decided to convert them and then burn them in using Avidemux. Now how do I use the tool to split my video into multiple fragments, and save one selection as an image sequence of png files?

[cjketle]

Solveig Video Splitter can do this (been doing it for years with H264/SRT in MKV). Unfortunately it has now gone subscription only which makes it a bit pricey for occasional use so I stick with the old version I purchased some time ago. Does frame accurate cutting encoding only the balance of cut I frames which makes it fast.

Can it encode videos to lossless formats like FFV1?

[cjketle]

Not on their current codec list (H265/HEVC, H264/AVC, MPEG-1, MPEG-2, MPEG-4, DIVX, XVID, MJPEG, WMV1, WMV2, WMV3, MPEG Audio, PCM, AC3, AAC).

Have you tried Lossless Cut? This uses FFMPEG as the engine and claims 'Experimental Smart Cutting' though I could never get that to work. That certainly keeps subtitles when cutting TS files, YMMV.

Solveig Video Splitter dont re-encode the video . If the input MP4 AVC output is MP4 AVC. If its MPEG TS, output is MPEG TS
