In some games perhaps there is another voice chat user that starts using really unacceptable words or even have inappropriate images (e.g using an in game custom "spraypaint" that is basically ****, or a profile picture).

I would like to suggest adding a "VOD Editor" which, like the highlight editor, you can select a range of the video (and zoom in, to narrow the ranges), and be able to soft-censor or hard censor the video.

A soft-sensor on the video would apply a blurring effect to it, where the entire video becomes blurry.

A hard-censor would be replacing the video with a black screen, if the offensive imagery would be obvious even with a blurring effect.

A censor for the audio (e.g complete silence, muted like if there is copyright music detected) would also be nice for if people in game start spouting unacceptable filth that you would like to protect your viewers from.

At the minute the only way to do this is to download a VOD, edit it locally, then re-upload it. These blurring, blackscreen and audio mute effects, could be applied by the vod player in real time, rather than hard coded into the video, to prevent any need to download, edit and recompress before uploading, or even some other processor intensive version of this on the twitch servers.

This would be useful in all manner of cases:
= In game players using harmful imagery or speech.
= If a streamer ALT-TABS mid-stream and for a split second their personal information is displayed.
= If a channel viewer redeems a text to speech reward which makes the TTS say vile things before this can be stopped.
= Anything else where the streamer is suddenly subject to any visual or audio abuse which puts their VOD in violation of the twitch TOS, which otherwise means deleting their WHOLE vod.
