"The problem"
On Twitch, there is a button called "Watch full video" under clips. Its purpose is simple and very useful: it allows users to find the exact moment in the original VOD where the clip comes from.
The issue is that this button currently works poorly and is not precise.
Right now, Twitch relies on the clip creation date and time to determine where to redirect in the VOD. However, the time a clip is created does not necessarily match the moment where the clip actually starts in the live.

Concrete example:
A moment happens during the live at 2:32:02.
Someone creates the clip 30 seconds later.
As a result, the "Watch full video" button redirects to 2:32:32, which is the wrong moment.

Even worse:
If a clip is created hours or even a day after the live ends, the "Watch full video" button is sometimes not available at all, even though the VOD still exists.

"Impact"
This button is heavily used by streamers, video editors, and people who simply want to have the global context of a clip.
Because of this behavior, the redirect is often inaccurate, users have to search manually in the VOD, and the feature becomes unreliable or useless in many cases.

"Solution 1 – Use chat messages instead of the clip creation time"
The idea is to stop relying on the clip creation timestamp and instead use the chat, which is already perfectly synchronized with the VOD.
When a clip is created, chat messages usually appear inside the clip. The system could take the first chat message visible in the clip.
Then, it would identify the exact moment when this message appears inside the clip, calculate the time difference between the start of the clip and that message, and find the same message in the original VOD chat, which has an exact timestamp.
Once this is done, the same time difference can be applied in the VOD to find the real start of the clip, with much better accuracy.

This would work even if the clip is created long after the live ended, rely on data that already exists (chat), and make the "Watch full video" button accurate and actually useful.

"Solution 2 – Time-based ID tagging inside the VOD"
This solution is based on a simple tagging system inside the VOD.
During the live, the VOD would be internally marked with unique identifiers at regular intervals, for example every 10 seconds. Each identifier would be unique to that live and tied to a precise moment in time.
When someone creates a clip, in addition to capturing the video and audio, the clip would also capture the identifiers corresponding to the segment it comes from.
Later, to find the clip’s position in the VOD, Twitch would simply match the identifiers contained in the clip with those in the VOD. This instantly gives the exact timecode where the clip starts in the original live.

Because the identifiers are generated during the live itself, the result is extremely precise, it does not depend on when the clip was created, and it works even if the clip is created days later.

"Conclusion"
The "Watch full video" button is a great idea, but its current implementation makes it inaccurate or unusable in many situations. Changing the way clips are matched to VODs would significantly improve this feature and make it reliable again.
I want to clarify that I am not an expert and this is not my field. I don’t know what implementing this would technically involve, but I hope this issue can be addressed, because this feature is important and widely used.
