Hello everyone. I have not changed any Screen record setting in program and running like this

Framerate 60 (auto)
Resolution: 1920x1080
Keyframe 150
H264 HVENC
Gtx 1060
7700k Intel Cpu
32gb ram
Ssd disk(s) from samsung x 850 and 950

Problem im having: described
I recorded just fine on Netflix and filesize around 4 - 7GB /hour. Then wanted to record a few shows and movies on Amazon Prime but got blackscreen and only audio (Firefox) so i switched between H264 in Settings menu to Mpeg4 and HEnc and tried also H264(CPU). Before i realised i could try with Google Chrome.... This worked so i switched browser.

1. Started recording Flintstone cartoon. 1h 30min and was schocked when filesize was 51gb...... I figured something was off so i tried changing between the default settings again and no success.

Compared the filesize from an Recording just an hour before on another cartoon movie that also is 1h 25min. Filesize there 7.8GB :/???

Tried recording this 50gb movie in only 1minute and getting a file of 400mb. What is happening? Is bandicam having difficult time here or... Something weird.

Tried install / update to latest Bandicam still no success on why filesize suddenly went berzerk for a normal movie length. Any tip?

Data are
mpeg4 part10 HVenc (av1) 24.03 fps

#1 1st movie
7,8 GB
1h 30min

#2 2nd movie
51 GB
1h 28min

I used the exact same preset and also tried Switching around but cant understand this. Is something broken. Or are this particular movie so "cartoon grainy" That the codec are having difficult processing the material that im capping?...

Sorry i posted on my phone and in the wrong section. Could any moderator change it to [Bandicam] thread section instead?

*update*
Here i have recordings made with Bandicam before everything gets so big. These are normal Screen Recorded content with no edit or any settings changed. Does anyone know why this is getting so big suddenly after i switched Encoding setting back and fourth in the menu... then switched browser and realised that settings was not the issue. And now ive gotten this issue instead where it seems to save my screen recording Uncompressed all of the sudden. Where i earlier was recording just fine with much much smaller files.

Hello paddingtonbear,

The file size is variable depending on the target fps, scene, codec and etc.
