Using OBS 1080p60 50 000 bitrate. Recording for 5 mins, so I watch the 5 min long rec.mp4 in VLC. If I just let it play it works good. If I try to go forward in the clip it just buffer for like 20-30 seconds before it jumps to the time I forwarded to... Same in VLC and Mediaplayer.

Question / Help NVENC extreme buffering when watching the recorded videos in VLC
- Thread starter Darker
- Start date
There may be 2 possible problems:
1. Very high key frames intervals may slow down seeking a lot. Higher key frame intervals have slower seeking.
2. FLV may need to read all the time stamps from the start when seeking forward which may be slow. The bigger the FLV filesize, the longer it will take to seek to the end.
If they are FLV file, it can be converted to MP4 or other formats using FFMpeg, OBS-MP, or other tools.

The files are mp4.
The first possible problem (key frame interval) still applies to H264 encoder in MP4/flv/something.The files are mp4.
It may help if you can show us your log file as it shows lots of information to look for possible wrong configuration.

If I lower the bitrate from 50 000 to 3500 it works much much better. Here is the latest log file, recorded with 1080p48 and around 30 000 bitrate this time (same issue though): https://gist.github.com/anonymous/7c8a1046cc1dafe937b3

Change keyframe intervals in advanced settings? I found another thread you may want to look at.
