Did you use AVI or MP4? and what codec, video and audio?

Mostly of my job is done recording as Motion JPEG and PCM audio, then Bandicam wraps it as AVI.

Editing is done with Premiere, Pro CC 2014 for complicated things, but if only doing a funny tutorial or clip about a battle I found that Premiere Elements is more than enough and very quick. It just misses the 2 pass option when encoding. But you can compensate that giving an extra 5 Mhz to your planned quality.

To the OP -

I think the issue is that you're putting "100% quality".

With H.264 codec, you don't need 100% quality. You can reduce it to say, 80% or even less, and the quality will look fine. Of course, "quality" is subjective and everyone's threshold is different. For me personally, if I use nvidia's H.264, I find that I can drop quality to around 60% and I still find the image "good enough" for me. With other codecs, such as MPG or MJPG, I might need to dial it up to 90% or so to get it looking similar.

The higher "quality" you specify, the more CPU needs to work to "get the image looking good".

If you're looking for "lossless" recording, I think you can use the built-in RGB or YUV methods. I haven't played with those yet so I am not sure what settings to use, but if you're sticking to H264 you don't really need 100% for sure.

ps: I record videos exceeding 45 mins normally and haven't found audio loss in any of them yet. Since I now have a nvidia GPU, I use the native H264 in the GPU instead of vfw's codec. The difference in CPU usage is night and day - there is almost no impact at all on the game during recording if using the native GPU H264.

Thanks everyone.
I will certainly try to down the quality with h.264 codec.
Today I did alot of testing with different codecs, and found that lagarith lossless codec are recording very well, no frames skipped at all. And the quality are awesome as well. Now I will test dropping quality on h.264.
