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!

That's 1,000,000 new users in 9 months!

I remain the only person behind everything related to Shutter Encoder 😉

Long life to Shutter Encoder!

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
