    Hello folk.

    I wanted to ask you kind folk if you could help me with a slight problem which I'm having. I'm new to video editing and I only do basic stuff for my videos since the videos I am working on are gameplay videos I upload to Youtube.

    Now what my problem is that my recordings are split into few files and I want to group them all into a single video, which I do simply by adding new clips to the end of the previous ones, however when I do that there appears to be some sort of sound cut where it's kinda obvious that the clips are added one after another and I'd rather fix this.

    Does anyone know what causes this and how to fix it ?

    My video editing program is Vegas Pro 13.

    I downloaded and recorded the problem with OBS:

    PC Specifications are:

    CPU: i5 2500K (Overclocked to 4.5 GHz)

    GPU: GTX 980 Ti

    SSD: Samsung 850 EVO (where Vegas Pro is)

    HDD: Samsung Spinpoint 1 TB (where my videos are)

    RAM: 8 GB

    Don't record into multiple files :-/

    Easier said than done, Shadowplay does it by itself when the file reaches 4 GB.

    In that case, you might want to look into recording the audio separately into a single file with another tool, and set shadowplay to not record audio. This might result in audio desync though. But it's worth a try.

    Also, have you tried doing a LOSSLESS concatenation of the mp4 files? With something like:

    http://www.mp4joiner.org/en/

    If you combine the files with that, does the resulting mp4 still have the audio gap?

    Nice, it seems after there is no audio gap or there is very little of it (maybe just my imagination tho), thank you for this, I'm just going to test if the quality changed.

    It's a lossless merge of files. "Lossless" means a 1:1 copy. Same data, no re-encoding of the video.
