Recording only plays from beginning. Cant skip through video.

[ams ken]

Hi everyone!

I am currently wanting to start using OBS over ScreenFlow but I have some issues. I read that its best to record in MKV or FLV over mp4 so I have changed to recording with that and I am also recording on to an external Lacie Hd (I was told less strain on the computer)

Now, when I come to playback the recording its fine if I just watch from beginning to the end but as soon as I try to skip through the video to check it, it starts to freeze and glitch. How can this be fixed? I have attached some screenshots of my screenflow settings to help...

I also need to be able to convert to mp4 so any advice on the best way to do that would also be much appreciated!

Thanks in advance!

Upon further looking it looks like when I skip it will play but it takes up to 5 seconds to start playing...
