Play only current segment

[DanielSWolf]

• I have tested the newest version from GitHub: https://github.com/mifi/lossless-cut/releases/latest
• I have checked readme and Known issues / Troubleshooting
• I have searched for similar issues

I sometimes want to check whether the start and end point of a segment are correct. To do that, it would be helpful to have a way to play just the current segment: start playback at the start of the segment, end playback at the end of the segment.

For long segments, it would start playback at the start of the segment, then manually jump to a later part of the segment and listen to the rest until it stops at the end.

see #253

Thanks! I saw that issue, but it explicitly mentions previewing "the merge", that is, all segments as one seamless playthrough. My use case is previewing a single segment in isolation.

[markusd1984]

I suggested the playback of segments e.g. 10 secs of the beginning and ending to check them, thus I agree it's useful.

#253 (comment)

An option to just check the selected segment Vs all would be great.

[DanielSWolf]

I agree that both might be useful.

I'll leave this issue open for the time being. @mifi Feel free to close it if you feel that the two topics are sufficiently similar.

Maybe a loop icon that can be cycled through to change playback mode

1. loop selected segment in full
2. loop through all segments in full
3. loop beginning and end 10secs of all segments
4. loop off

(Ideally for # 3 a setting to select the in/out preview length in seconds)

yeah IMO 10 seconds is way too long.. 1-2 seconds before/after would be good (to quickly check accuracy of the cut).

[markusd1984]

Sometimes 1-2 seconds are fine and sometimes one might need a few more to get the feel of the clip beginning/ending, but that's why a setting for the duration would be ideal.

But yeah this would help a lot because currently one has to export the segments and then open all files individually and seek for the beginning/endings.

That's why even better I suggested if it where possible to have a more accurate preview by letting it export and play back the exported video file in LC in sync with the timeline (roughly).

[markusd1984]

Didn't realise the create chapters during export allows for importing the new merged file with the segments displayed as chapters (even utilises the labels if present) #253 (comment), thanks @mifi !

which could be a good approach for a export results preview/review workflow and enhancement to have 1) an export setting to auto load the new merged file with chapters and then 2) a playback mode to play only current segment or all segments as well as a playback mode to play only a couple of seconds of the beginning and ending of all segments/selected segment.

[mifi]

have now implemented:

• Play current segment
• Loop current segment
• Loop beginning and end of current segment

They will be avail as bindable keyboard actions

has this been implemented yet?
