Windows: Opening image sequences from the cli

[pleprince]

Describe the bug

The docs states you can open image sequences on Windows using:

C:\Program Files\xSTUDIO\bin\xstudio.exe C:\Users\JaneSmith\Media\exrs\exr_sequence.####.exr

it actually fails:

E:\Ynput>h:\programs\xstudio_1.0.0\bin\xstudio.exe H:\AYON\projects\AY_CG_demo\shots\sh010\publish\render\renderLightingMain_beauty\v001\cg_sh010_renderLightingMain_beauty_v001.####.exr

[2025-08-27 18:35:34.239] [xstudio] [error] Failed to load media 'No frames specified.'

It doesn't work until the frame range is specified:

C:\Program Files\xSTUDIO\bin\xstudio.exe C:\Users\JaneSmith\Media\exrs\exr_sequence.####.exr=1001-1050

Also note that passing only the first frame resulted in an exception:

E:\...\programs\xstudio_1.0.0\bin\xstudio.exe H:\AYON\projects\AY_CG_demo\shots\sh010\publish\render\renderLightingMain_beauty\v001\cg_sh010_renderLightingMain_beauty_v001.1001.exr

To Reproduce

1. Use any windows machine.
2. Locate an image sequence.
3. try all formats and see which works.

Expected behavior

• The generic /path/to/frame.####.exr should open the entire image sequence.
• /path/to/frame.####.exr=0010-0030 should only be necessary when you want to limit the frame range.

Desktop (please complete the following information):
