@ jozee
The easiest way to do this is manually... That is, right click the playhead of the video clip (preferably while in Preview) to set your IN and OUT points. Alternatively, you could set-up "Shortcuts" to do this, but I don't think it would be any more convenient. Hope that helps.

Ice thanks ice but that wasn't my question, i need to move frame by frame to get a finer ins and outs, i want to mark in to e specific frame. it is next to impossible with the mouse thanks

It is not optimized for media playing or playout management. It's a live production software

DWAM- I do not think the OP is trying to do anything extraordinary. Tricaster can do it. Others can too.

It's a live production software I disagree, a playout software does automation, scheduling and commercial brakes, moving frame by frame its basics for VTR player, vmix is a professional program, this is not VLC or media player, vmix should have the option of scrubbing frame by frame with keyboard or external controller. i saw somewhere that the vmix replay software can do it using shuttle pro, will it work with vmix?

vMix features for Instant Replay are for instant replay only with specific codec being used.
Frame to frame accuracy is not available for Mp4 files using Long GOP compression. Mark IN can only be on I frames

Why don't you just trim your videos so that they match exactly what you need?

Well simply because it's not implemented Richard and not so many video editors, apart from leading NLEs are able to do this. Moreover vMix is not an NLE, it cannot work as an NLE (which might use previous keyframe transparently in the background in order to render from any "in-between" image), vMix has to focus on realtime. I'm not saying it's impossible, I'm saying there are technical reasons why vMix does not allow this so far. It's not MP4 (which is a container, not a codec) but long GOP compression which makes it difficult. In a Group Of Pictures, only the first one is a reference image, called I for Intra, is allowing to be marked for index. If you use intermediate codecs or AVC-Intra, you can mark in/out any image, but with such codecs the footprint on CPU is not the same. If you want more information, read this: http://www.tiliam.com/Bl...se-long-gop-video-codecsor https://en.wikipedia.org/wiki/Group_of_pictures

thanks DWAM for the clarification. I am still not convinced that vMix cannot do it, and understand that it would be at a cost (in developer time and CPU load).

It would seem to involve taking a video and forcing key frames at the desired spot which would be cpu intensive.... although for a brief duration. http://www.videoredo.com/en/index.htmDoes this better than any software I have ever used. Its really remarkable- allows us to edit 3 hrs of video and output 2 minutes with no rendering. I would recommend to the OP to use this to trim videos.
