Dropped frames

Hello!

I have a big problem again. It's a problem with dropped frames in many codecs when I set FPS limit at 30. I used a lot of codecs: H.264 AMD APP (VBR and CBR), Xvid (VBR and CBR), MPEG-1 (VBR and CBR) and Motion JPEG. In all of this codecs I have dropped frames. In game I have a stable 30 FPS. Please, fix it! I use Bandicam 1.9.2.455.

I can actually say that I had these kind of problems. I was capturing Tomb Raider 3 and from time to time the video's framerate goes choppy for quite a while. Note that the game is running at solid 30 and there's more than enough CPU/GPU juice to handle this. Pretty sure that the codec doesn't even matter.

Here's probably one of the obvious samples:

The framerate starts to jump from 20 to 30. (eventually it does lock back to 30, not shown in the vid).

Try choosing an external codec: Lagarith.

I've set mine to Lagarith, using RGBA colourspace, multithreading and I turned off (unticked) "Prevent upsampling" setting, so that it works with editing software without problems. You may choose a different colour space than RGBA, try it out.

I tried use Lagarith. It's the same.

Developers, please, don't ignore this problem! It's important!

The problem with dropped frames is very difficult to recreate/fix.
If we can recreate the problem in our PC, we will fix it...

We're sorry that we couldn't give you a good answer.

Please, try to test Assasin's Creed 4, Battlefield 3, Metro: Last Light, for example. Important! - Set fps limit in Bandicam at 30! Use this settings:
Full Size, 30.00fps, codec - H.264 amd app (VBR 100q and CBR at 30000 kbps) or xvid (VBR 100q and CBR at 30000 kbps) or motion jpeg 100q.
My problem: When I record video in all of these games I have STABLE 30 fps when I set fps limit at 30. But in recorded video fps dropped from 30 to 20 in some moments. I converted this video and it has the same dropped frames. And I tried to use an external codec, and recorded video has the same dropped frames at the same settings.

Hmm I'm still unsure what the problem is. Bandicam making the game lag?

What you could do is use your phone to film the monitor, then start the capture, play a game and upload both videos. Then we could see the issues easier :)

Maybe edit the videos side by side and sync for easy visual comparison.

No. The game runs fine. That's the problem. However, the captured video files at some points has low framerate.
Sometimes happens when I capture 20-30 minute long videos. It's not easy to recreate, but it happens.
I have a speculation. Could be related to hard drive fragmentation. In this case - free space "fragmentation".
The raw of the sample I posted was split into 16 fragments. But this is unconfirmed, because I have even more fragmented videos and they're fine.

I didn't post about this because I didn't think that it was a problem on my end. But it seems that I'm not alone.

Are you recording to a dedicated hard drive (used ONLY for recordings, not used by the system and the game)? If not, give it a shot. If yes... then yeah, it does seem like an issue to me.
