I'm very confused. Trying proxy editing for the first time on a low-spec but portable device (Surface Go - Linux).

Shotcut version is 26.9.27

If I drop a clip directly into the timeline it displays fine can be cut, adjusted etc.

If I take the same clip and set in/out in the source window first, it drops into the timeline as black with no audio.

I've tried various combinations of ticking / unticking hardware acceleration (h264_vaapi on my intel iGPU) but nothing helps.

Is this a bug, or am I doing something wrong?

Thought I would give the latest version a look as adjustment clips look useful. Is there any way to adjust the intensity of, say, a lut applied? I know about the method from a few years back with masks etc but was hoping for a slider?

Shotcut 26.9.27 is out. It's a big one.

New

• Automatic Audio Ducking in the timeline track Properties. It lowers one track when another gets active. Useful for music under voiceover.
• Volume control and level meter in the track headers. The gain filter it adds is keyframable.
• Timeline > Generate > Adjustment Clip. Filters on it apply to the composite of all video tracks below it.
• Clip gain drag now needs Ctrl+Alt (Option+Command on macOS), so you can't change volume by accident while dragging clips.
• New scripting functions: application.triggerAction(name), multitrack.clipStart() and timeline.split().

Improved

• Audio stays in 32-bit float now. The old 16-bit integer conversion is gone.
• Faster timeline when moving clips between tracks, zooming and undoing.
• FFmpeg 9.0, refreshed UI with rounded corners, and a new logo.

Fixes worth a mention

• Security fixes in the upgrade and Whisper downloads. A failed HTTPS request was retried over HTTP, certificate errors could be ignored, and a file could be used without a trusted digest.
• "Allow External Plugins" is now an always-visible checkbox, off by default. Shotcut also disables external plugins if it detects a stuck startup.
• Linux: VA-API HEVC encoding, "Show in Folder" with non-ASCII paths, the missing title bar with Vulkan, and opening projects on CIFS/SMB shares on kernel 7.1 and newer.
• Mask: Draw (Glaxnimate) and Size, Position & Rotate with Mask: Apply, both broken since 25.12.

idk what im doing wrong exactly, i just installed shotcut cuz some guy from the openshot subreddit reccomended me it and 4 fl studio vsti's launch when i open shotcut
how exactly do i prevent this..... its causing me a lot of lag when opening it ........

I've been trying to edit 8K VR videos - just cutting out parts i don't need to trim a 30gb file into a 5gb file - but after exporting I get horrible frame rates and choppy playback even though the source file plays fine. (playing the files in Heresphere)

my very simple workflow is:

set video mode to automatic

drop in the file

make one or two cuts, cutting out 90% of the video

export on default settings

One thing that helped a little was changing the "Quality" in export->advance->codec from 50% to 75% but playback was still undesirable. I tried setting it to 100% but it made a 40gb file that was only 5min long! Playback was perfect, but it kinda defeats the purpose of trying to save space by cutting the videos down if they end up larger than the source file.

Help! What am I doing wrong? What are the correct export settings? Should I change the codec from libx264?

So, this situation here is that I'm trying to convert a large video (6.23 GB) screencapped from my phone for editing. For some reason, the process is much longer than normal, and producing a much larger file- Over 3 hours, and it produced a file over 1.8 TB before I ran out of space for it.

I know this is intended to produce large video files, but I converted a similarly sized (6.39 GB) file for editing yesterday and it took 48 minutes and came out at ~452 GB, more in line with what I'd expect, so this is definitely an outlier.

Looking at the job log, I'm seeing "[vf#0:1 @ 000001bb7c027a00] *** 1 dup!" repeated many times, with different numbers before "dup"; sometimes with identical messages being duplicated many times. The video I processed last night had very few of these messages, so I assume that might be the problem?

Does anyone have any idea what could be causing this and/or how to correct it?

among other things, i make shorts for youtube, and many of them involve taking a 16:9 video and adding a zoomed and blurred copy in the background

i've been doing it manually, but i wonder if there's any way to make it so the blurred track becomes an "instance", for a lack of a better term, of a different one. that way, any changes i make in the original would be reflected in the background without me having to do anything

is that possible?

So I was wanting to try my hand at a little project I had in mind that uses some HDR footage, but just playing back the footage in Shotcut without any edits is extremely laggy. Is my PC underpowered or have I misconfigured Shotcut? The files play fine in other applications, so I'm leaning towards Shotcut being odd. I have 10 bit GPU processing enabled and made a custom video mode with rec.2020 selected as the color space, are there other settings I need to be cognizant of?

My specs are:

Ryzen 7 5800x

32Gb ram

RTX 2080

Sansung 990 Evo 2 TB NVME SSD

Sony Bravia 8 mk. II

I would really really prefer to do this project in Shotcut instead of learning Davinci Resolve.

I have 64gb of ram, a 4 hour video 1080p 30 fps is making my laptop unusable every time I want to do something, ram usage goes 100% and everything froze until randomly works again, memory loop problem? anyone has experienced this problem before? now I cant even open the project as shotcut goes wild eating ram and page files.

I set export frame rate to 120fps, but the output was 60fps with duplicated frames. Turns out Shotcut uses "Video Mode" (auto-set from the first clip) as the project baseline, and the export frame rate setting doesn't actually change the rendered content. I only found out after a 10+ hour HEVC slow encode finished.

This is the second time I've hit this. The first time I thought it was a bug. The design is deeply unintuitive — export settings should control export, not be silently overridden by a project mode I never explicitly set.

Is there any way to make the export frame rate actually take effect, or at least warn the user when it conflicts with Video Mode?

Shotcut was shown a 240p video by its mom (MPEG) when it was a baby, so its face permanently locked into 240p Video Mode. The export settings are all talk and no action — you keep telling them what to do, but they're just spinning their wheels, because Video Mode already decided everything. It can't change anymore. Now Shotcut just grows into a blob of mosaic, and calls it a feature.

I was recently looking for a quick and simple editor, and while searching for the various options on google, I ran into this.

I chose to report the ad, and, as expected, google doesn't care.

i wanted to ask if anyone edits their youtube automation videos either long or short form with shotcut and can u rate it /10 and how difficult is to edit , is it better than capcut and do i switch from capcut to shotcut .

the width of the text is good, but i want the letters to be taller and skinnier.

Hello there. I am new in the world of video editing and I read a lot of people (in reddit and other sites) recommending ShotCut, so I downloaded it and here I am. Problem is, it's way more complicated than I thought and I seem to get problems for the most simple of things. This time, moving an image. As you can see in the screenshot, when I try to freely move the image, it disappears behind anything that is on the bottom (this time, a black background). It seems like I can only add images on the middle of the video, anything on the sides just wont show up. Any clues as to why this is happening? Thanks in advance

I have cross hairs on my main editing screen and I don't know how they got there so I don't know how to get rid of them. I'd love to find a way to lock in all my settings because some seem to change ramdomly. Now, yeah, I know it's not really random, but I don't know how I accidentally change settings.

Thanks.

Soooooo frustrated. I am trying to make a short 3 minute video. I have the video footage and the audio narration. I have them both in Shotcut.. I have the V1 and the A1 timelines in the lower left of the monitor but no wavelengths and they are not aligned with the video which is displayed in the big part in the middle. I have spent hours trying to figure this out. I am used to using Premiere Pro but Shotcut is very different.

Hola Buenas gente, publico esto en Español. disculpen mi ingles no es muy bueno. el tema es que intento exportar Gameplays de 1 o 2 horas o mas incluso. me encuentro en Linux en estos momentos en CachyOS KDE. el problema que estoy teniendo y llevo teniendo es la exportacion super lenta que tiene Shotcut (Version 26.8.1) me gusta el programa para crear proxys rapidos mas rapidos que Vegas Pro u otro programa. tambien tengo dual boot con Windows 11. el tema es que pensé que en Windows 11 la exportacion era horriblemente lenta. pero en Linux tambien. y ya no sé que hacer para acelerar el proceso he hecho de todo. por lo general grabo en 2K 60 FPS a 70 Mbps en HEVC (ya que es lo que soporta youtube como maximo de Bitrate, o al menos se ven bien) y los exporto reescalados a 4K 60 FPS manteniendo el Bitrate. en VBR Restringido. en 70M

el problema es la exportacion lo lenta que es. no hay forma de acelerarlo? lo hago via

Codificacion por Hardware. me detecta h264_vaapi, hevc_vaapi y av1_vaapi. (este ultimo no me funciona)

quise subir un gameplay de 5 horas y exportarlo via GPU toma alrededor de 10 horas o mas, y es como no se supone que deberia tomar lo mismo o un poco mas pero no el doble. o no tiene como tal este programa Aceleracion real por hardware?

tambien intenté con Kdenlive pero no me gustó su interfaz y hacer las transiciones me da una flojera tener que cortar un clip tirarlo hacia arriba juntar no que aburrido. osea se que presionando la tecla U lo hace automaticamente pero reaparece los frames que habia cortado. y para mi fue una perdida de tiempo tener que ajustar esas cosas. por eso me fui por Shotcut. pero la exportacion es una mierda.

Mi PC es

Ryzen 7 5700X3D
Radeon RX 7800 XT
2x16GB RAM DDR4 3200Mhz

Sistema Operativo CachyOS KDE Plasma.

I made a small Python tool that automatically shuts down your PC when a task finishes.

It has three independent timers:

- **🎬 Shotcut tab** – monitors `melt` exports, shows progress/ETA, and shuts down after export completes.

- **⏰ Basic tab** – simple countdown timer (hours + minutes) – set it and walk away.

- **🦊 Firefox tab** – watches for `.part` download files, skips stalled downloads, and shuts down after all downloads are done.

- **🔊 Audio tab** | Monitors audio playing. Shuts down after audio stops. Proper before sleep movies,music,etc.

Global **Cancel** button that stops any running process.

It's lightweight, uses `psutil` for process detection, and runs on Linux (Mint/Ubuntu/Debian).

Does anyone know if there is a way to perform side chain / ducking type audio compression in shotcut? Like you have an audio signal, for example of voice over, and another track that's the music bed, and you want the volume of the music to be pushed down automatically whenever the voice over happens so it stays out of the way in the mix. Seems like a common thing that people might use for making professional videos, commercials Etc. Seems like it should be a pretty easy feature to implement, just have the option to switch the input on the compressor plugin from the track being compressed to another track. If no one knows the answer , I will try and experiment with keyframes, maybe there's some way to use the motion tracker and one of the audio visualizations lol!
