Hey there! I just discovered this great app. Could you tell me how to change stab parameters? ChatGPT gave me some code (mostly how to reduce accuracy) to type but problem is that analysis and encoding are two different passes and the app does it all at once so i can't type both parameters in the same line and am stuck.. How to deal with this?
Hello,
I am experiencing an issue with Shutter Encoder on Arch Linux where the "Hardware acceleration" dropdown menu is greyed out and stuck on "none". I am unable to select Intel QSV, despite it working perfectly on my system.
System Information:
The Issue:
On Arch Linux, the "Hardware acceleration" option in Shutter Encoder is greyed out and cannot be changed from "none". Therefore, I cannot use Intel QSV to encode. However, on my Windows 11 partition on the exact same machine, the Intel QSV option is available and works flawlessly.
I have verified that this is not a driver or system-level issue on my Linux installation:
i915 driver, intel-media-driver, and oneVPL-intel-gpu (required for 12th Gen Intel QSV) are all correctly installed on my Arch Linux.-init_hw_device qsv=hw).--enable-libvpl. When I run encoding directly from the terminal using the system FFmpeg, Intel QSV works perfectly and utilizes the iGPU: ffmpeg -i input.mp4 -c:v h264_qsv -global_quality 23 -c:a copy output.mp4 (This encodes at a much higher FPS using the Intel GPU, proving the hardware and drivers are fully functional).libvpl and QSV). However, the GUI dropdown remained greyed out.how to fix this?
Thank you for your time and for this great software!

Bonjour, souci avec la dernière version, je n'ai plus d'image dans le player, j'ai essayé différents fichiers avec différents codecs, mais toujours pas d'image. Suis sous Windows 11.
it clicks for that button but not the rest
Hi Paul,
First of all, thank you for creating Shutter Encoder — it's an excellent tool!
I have a vertical video (2160×3840) that I want to downscale to exactly 1080×1920 while keeping the original aspect ratio. I don’t want any stretching, cropping, or black bars — I just want a clean downscale of the original content.
I tried setting:
Scale → 1080x1920 or 1080:1920
Scale mode → Adapt
Force display → 9:16 (and also tried without it)
But the video still comes out stretched/distorted.
Could you please tell me the correct step-by-step settings to achieve a proper downscale in this case?
Thank you very much in advance for your help!

I remain the only person behind everything related to Shutter Encoder 😉
Long life to Shutter Encoder!
So I learned how to put the images and turn it into a mp4 in the right framerate, the only problem i have is that the animation I'm making is in 480 x 270 and when the program upscales it to 1920 x 1080 gets a bit blurry. Does anyone knows what setting I could use to keep all quality?
When converting multiple clips, some of them get randomly shortened (it seems to shorten longer clips the most) for example 40sec clips is converted with duration of 23sec only.
Is this a bug or am I missing something?
I just want to convert my LongGOP H265 clips to Prores for faster editing. Not changing much.
ever since switching to linux (kubuntu) shutter encoder just hangs after i run a function. it completes the function perfectly fine but the app freezes and loads forever until i kill the process.
its just stuck at zero percent
