As stated in the title, we have a video added as an input. When we switch to that input, it skips the first 5 seconds and the continues playing the rest. Any ideas? I see there are in and out points and I have reset these.

Could be a corrupted header. I would convert to mpeg2 and see if it is still there....

I have the same issue using an external drive on USB3. I always attributed that problem to being an external source. Are you using one by any chance ?

I actually saw similar problem once, but I can't remember if the video file were located on a external drive..

Have you guys verified that the solution were simply to put it to a local drive?

I guess it's incorrect keyframe in this video.
Try re-indexing it and make sure you have keyframes every 2 seconds for example and especially one on the very first frame.

Oh, You know what? The video might have been on a USB flash drive. I'll check that.

Not sure what keyframes are but I suspect if I Google it, I'll find something.

And the idea of converting to MPEG2...... I guess I would use handbrake for that?....

I moved the video to the local disk. The first time I played it back, it worked, but each time after that it still skips about 5 seconds. I converted to mpeg-2, but it looks like that reduced the quality. I haven't gotten to test if the issue persists with mpeg-2.

Even with Mpeg-2 it seems to have a problem.

I removed .mp4 from the list of formats that playback with FFMPEG and that fixed it. Any ideas on why this would be the case?
