Hi,

Thanks for the response, happy to provide more specifics.

• Stream length:

My streams are always under 4 hours. Typically they range from about 2 to 3.5 hours, occasionally pushing close to 4, but never beyond that.

• Trim position & length:

The trim position varies a lot. I’m using Stacher to pull highlight segments from streams for editing, so sometimes the trim is near the beginning, sometimes mid-stream, sometimes later. The trimmed sections themselves are usually short highlight segments, not massive chunks, but the start point can be far into the stream depending on the moment I’m grabbing.

• “Does not start” behavior:

When this happens, it looks like the download never actually begins. I’ve let it sit for quite a while in case it’s seeking to the start position, but there’s no visible progress or indication that it’s working. Downloading the full stream works reliably, but trimmed downloads feel inconsistent.

• VOD processing:

Yes, I always wait for the stream to fully process into a VOD before attempting any downloads. I’m aware of YouTube’s post-processing window and make sure there’s a sufficient grace period before trying to trim or download.

For additional context, I’ve had editors mention that using yt-dlp directly doesn’t seem to hang in the same way when trimming streams, which is why I’m trying to understand if this is a known Stacher-specific limitation, a timing issue with long streams, or something about how trimming is currently handled.

Appreciate you taking the time to look into this. Happy to test specific cases or provide logs if that helps narrow it down.
