Thank you for making this program, it's a godsend when it comes to quick-and-dirty video cutting.

Being able to seek directly to a keyframe would make splitting videos much easier and faster. If the user so chooses, this would reduce the number of options you have to deal with.

For example, instead of wondering if you should cut at 10:01, 10:02, or 10:03, you could see that there's a keyframe at 10:02, making the decision pretty easy.

This could be implemented as GUI buttons similar to the seek forward/backward buttons, a keyboard shortcut (ctrl+right, ctrl+left), and/or clicking on the seekbar itself (ctrl click, for example).

Not allowed to load local resource: file:///C:/Users/ndarville/Downloads/#foo\nar\LosslessCut-win32-x64\resources\app.asar/index.html

As you can see, the slashes are both forwards and backwards here; UNIX ones before the # and Windows ones after. Moving the folder to Downloads/ resolves the problem.

I don’t know much about handling paths in JS, otherwise I’d just do a pull request.

This is on Windows 10.

Tiny seek does not advance/go back frame by frame, but rather a few frames at a time. Is it because since the cuts are done without reencoding, tiny seek jumps between keyframes, ignoring b-frames and the like in the process?

A nice addition for lossles-cut would be to add J, K, and L shortcuts like most video editors have.

This isn't per se a video editor but I think it would make sense to integrate these shortcuts to find the perfect in/out point easier without using the mouse.

A bit more specific for each shortcut:

• K: act just like the space bar to play/pause the video
• L: start playing at 50% and increase the speed every time pressed.
• J: start playing backwarts at 50% and increase the speed every time pressed.

Keep up the good work 👍

Minor issue: after cutting one file, I drag in the next one but the title bar still displays the old filename.

Everything else about the new filename is fine - in particular when I perform the cut operation on the new file it gets a correct filename.

lossless-cut 1.9.0.0

By the way - thanks for this utility. It's a very nice tool.

Please consider releasing self-contained portable builds.

Thanks.

Request
Scrolling with the mouse wheel at higher speed (speed parameter adjustable in seconds skipping)
or
Use arrow-keys in combination with shift/ctrl/alt for different speeds (speed parameter in seconds adjustable for each combination)

Both forwards and backwards

First I want to thank you for creating this awesome tool.
It would be nice, to have option to crop video.

Whenever I start LC the initial window is placed with a comparable small window and centered in the mid of the screen.

When I move and resized the window, then exit and restart it the previous window size + position is not remembered.

Could you make LC remember it in the next release?

Thank you

I'm running into an issue where Lossless Cut will not open videos at all. I have tried confirming the FFMPEG path, tried different formats,etc. Is there a definitive list of what media works and what doesn't?

I want to trim an episode of a series, but standard sound is not English. Anyway to change this? If not, this is a feature request.

..Would like to ask if the interface can be changed in other languages? If it can be set to Chinese?

When a video has a # in the filename, you get a "ERR_FILE_NOT_FOUND" error with a console log entry like this:

/Users/jeroenp/tmp/1.0004-0014-Nathans%20Popquiz%20-%20Aflevering%20#69-4B7jYjVBPrw.mp4:1 GET file:///Users/jeroenp/tmp/1.0004-0014-Nathans%20Popquiz%20-%20Aflevering%20 net::ERR_FILE_NOT_FOUND

When playing you then get this error message:

This video format is not supported, maybe you can re-format the file first using ffmpeg

After renaming 1.0004-0014-Nathans Popquiz - Aflevering #69-4B7jYjVBPrw.mp4 to 1.0004-0014-Nathans Popquiz - Aflevering 69-4B7jYjVBPrw.mp4 it loads fine.

Two things:

1. Please correct the error message
2. If possible make loading files having # in them possible

My guess is that 1. is easy, but 2. might be difficult if it's not a URL encoding issue.

It would be great if program could auto-open file passed in command line parameter (we would than start this from another program) - at least for windows version.

example:
LosslessCut.exe X:\cut_135611_136858_Time-2016-10-26_18_00-Nova-TV2016-10-2618-00.mp4

Hi, just found out about lossless-cut and wanted to give it a try...
But any link I try on the downloads page gives me an error page about an XLM file instead of a file ?
TIA,

hi there

    I am trying to run lossless cut on win 10 pro x64, no matter what video i load i get the same response after a few seconds, please find a screenshot attached, be happy if you could let me know how to fix it or make an update for your app tnx !

Tried to trim a MKV file I made in Handbrake. The error message I get is "this video format is not supported, maybe you can re-format the file first using ffmpeg"

Here's the log

I have no idea what I'm doing™, but I see that the team that built Kap was able to vendor ffmpeg in their app:

https://github.com/wulkano/kap/search?utf8=%E2%9C%93&q=ffmpeg

It would be pretty nice for users not to have to set this up.

Auto update has been requested.
Or possibly download the latest file when pressing the menu. This requires us to build into the binary which release link it should download. (Linux has multiple types)

Video shot with Sony A7R II camera does not seem to be supported properly. After loading the video, only the initial frame is visible. Playback and other controls don't respond in any way. Taking a snapshot works but produces a jpeg file with just black.

I experimented re-encoding ffmpeg -i C0001.MP4 test.mp4 and with the resulting file lossless-cut playback and preview work but exporting results in just an audio file.

If we set a start time but not an end time, and try to export, we get this message:

However, if we set an end time but not a start time, and try to export, it simply assumes the start time is the beginning of the video, which makes perfect sense and is expected. Similarly, then, the end time should be interpreted as the end of the video, if none is set.

Possibly also other special characters

This applies only to html5 video tag. It tries to load file://your/#path#/#withhashes/file.mp4 and fails.
Possible fix: (this.state.filePath || '').replace(/#/g, '%23')

On Linux, exporting a screenshot creates a file called ****.jpg, however, trying to open that with an image viewer file results in the following error:

Error interpreting JPEG image file (Not a JPEG file: starts with 0x89 0x50)

After renaming the file from .JPG to .PNG, it works.

When playing the clipped video in VLC, the beginning is not displayed, only the audio. After a few seconds it starts to display the video.

In Windows Media Player, the end of the video is frozen and audio loses sync with the video.

Example attached.

Would it be possible to set multiple in and out points for videos, so that one can create a clip containing of multiple parts of the original video?

This could, e.g., be helpful to cut out commercials etc.

When using multiple video cameras and recorders it would be very useful to have the tool keep "Recorded date" timestamp metadata intact relative to the original video file, so that the exported clip would have timestamp with added offset relative to the starting point of the clipping. This way the clips from separate cameras could be easily/automatically synced in timeline.

Related issue #33

Maybe in the title bar?

Would make things less confusing when cutting bunch of files.

Thanks for the great tool btw!

Hi,LosslessCut 1.9.0 appears to be exactly the App I have been seeking for a long time, if only I could Run it! I have Downloaded LosslessCut-darwin-x64.zip numerous times, from github.com and videohelp.com. Whenever I Extract All on the downloaded Zip file there is no .EXE present.
I have atempted this Download & Extract on Windows 7 and 10 Systems, running Kaspersky or AVAST AV, using Chrome, Firefox, IE and Edge Browsers, all to no avail. I believe I have read of this issue arising before. Can you offer any suggestions to resolve please?

merging multiple videos could be also a good feature

I'm using a linux OS (not a distro): Solus os 1.2.1
The app is launched well, but when I select the area that I want, the video generated is empty but the file is created.

Hi, when I use LosslesCut on a Mac (macOS Sierra 10.12.23 (16D32) some edited videos have the following problem: video starts, I can hear sound but no video yet, only after a few seconds the video can be seen. From that moment the video plays correct (in sync). Publishing such clips on YouTube is not possible. The file can be uploaded, but can't be processed.
I have included a sample of such video.
uhlvjd.mp4-00.32.16.547-00.33.04.956.mp4.zip

Hi
I have a computer which doesn't have the greatest CPU (i3-4500U), when I run screen records from my FHD phone it plays smoothly on VLC but Lossless-Cut gets stuck with it (like about 3-5 seconds to response when trying to jump to some point in the video), so it would be very useful for me if I can just watch the video with VLC and then just feed the in and out time textually.
Since clicking on the in/out time is already reserved for seeking the video to that time maybe a double click can be set for manual setting.
Thanks
Ezra

Enhancement request: Display progress of cut operation, either with progress bar, percentage complete, or estimated time to completion.

Any plan to add audio waveform and a scrollbar with zoom in/out for time scale and thumbnails?
I ask because I'm currently using another app to cut long streaming files into pieces. Finding gaps between content is easier with a waveform (I look for empty regions) and thumbnails which can show standard intro/outro sections.

It would be nice to be able to press ? and have the list of shortcuts appear. It could also be an option in the top menu.

Enhancement: Set point in, set point out, set point in, set point out, etc.

Export = Multiple clips base on in-out points.

One thing I really like about other video editors when cutting is that when transversing the file they still play a fraction of the sound at the moment of movement. This is particularly useful when trying to cut a piece of video where the audio also matters, as you can have a better sense of when the important part actually starts (or end).

For a precise cutter like LosslessCut, where no reencoding happens, that would be extremely welcome.

great and fast software, thank you.
but there are some videos show "no valid source found" in handbrake after cut.

It would be great if this worked on audio files too. I get the error:

Whoops! ffmpeg was unable to cut this video. It may be of an unknown format or codec combination

I confirmed that FFmpeg could losslessly cut this particular file:
ffmpeg -i iKey_002.m4a -ss 00:46:30.094 -to 01:12:56.649 -c copy OutputFile.m4a

Thanks for making a very useful program. It allows non-tech people to do an extraordinary thing!

See #13 (comment)

@gleddamax So what you're saying is that if you cut from exactly 0 (the very beginning of the video), we should exclude the arguments -ss 0? That's easy to fix, just have to whether it breaks anything.

v1.9.0

Tried x32 and x64, it just basically closes itself automatically or something, it shows up on task manager for a split second and then vanishes.

Tried compatibility mode, executing as admin and to no avail.

Please fix.
--Thanks

I believe you can fix this by adding arguments to electron-packager like --win32metadata.ProductName='LosslessCut' --win32metadata.FileDescription='Simple, cross platform video editor for lossless trimming / cutting of videos' (see https://github.com/electron-userland/electron-packager/blob/master/usage.txt).

I'm not 100% sure which fields should have which strings.

I was going to make a PR but I am unable to test it as extract-ffmpeg errors with mv: cannot stat 'extracted/linux_ia32/ffmpeg-3.2-32bit-static/ffmpeg': No such file or directory on Arch Linux and NixOS, and the VAR=val command shell syntax isn't supported on Windows.

option to save as a lossless image format please

Hey! Thanks for the great app. I love the minimalistic design and the overall speed.
I just have a problem with some lost tag information in mp4 files. Thinks like cover, publisher, etc. get lost after cutting a mp4 file.

Here you see the original tag information in the mp4 file, created via MusicBrainz Picard:

And after putting it through LosslessCut the following happens:

I didn't test ist with any other video file formats.
I hope this get's fixed sometime in the near feature. Thanks!

i've made a pkgbuild for arch linux: https://aur.archlinux.org/packages/losslesscut/ but icon is sorely missing. currently an ugly placeholder is displayed instead. anyone able to make a nice looking icon?
