Framerate Mismatch on Desktop Recording

Wed Mar 25, 2015 9:46 pm

Bandicam could not record WQHD desktop at 60 FPS. Instead, it came up with 26 FPS and 30 FPS.

Oh. It turns out to be your shitload of software cuts the video at the end beacuse it can not sync the fucking frame rate!

Cool. Have you tried emailing tech support? You are posting in a section called "General Discussion." This is for user responses. Tech support comes in occasionally and should NOT be expected to even notice this topic, or at least not for a few days. And I think your vocabulary is scaring off people who may be able to help; I know I wouldn't want to help if I had any ideas.

If you really want to get anything on the move, it would be of great help to someone if they knew anything about your computer, your video settings, your Bandicam settings, etc. You know, the usual troubleshooting stuff.

Frame rate : 30.479 fps
Original frame rate : 60.000 fps
If you still can't get 60 fps, you can't always get constant 60 FPS if your computer isn't good enough.

(We can't increase the FPS on Windows because we use the GDI method for screen capture. You may reduce the screen size or use the 'DirectX/OpenGL window' mode to increase the FPS.)

Please choose the 'Prefer CFR' option and try it again.

You will get constant 60 FPS.

Hi cool_recep.
I got the same problem with the MP4 format setting.
Tried setting 50fps output was 29fps, when setting 30fps output was 26fps.

With the AVI settings there is no problem: set 50 get 50, set 30 get 30.

cool_recep, I'm impressed of the code you have attached - how du you get the code?
I only know how to use Properties on the filename to see the fps.

Cheers, Anja

You can use MediaInfo to get the code. It comes with KLMCP. Thanks for the AVI tip but AVI is like ages old...

Thanks for Mediainfo tip :-) Yes AVI is ages old like me - but I had a job that hurried and my video editing program (PowerDirector) either: could not load the MP4 / if loaded - reported error code 2 and so on. Thats why I tried the AVI profile - and yes, I was not proud of the result...
I don't like the answer you got from the Bandisoft employee:
"Even though you set 60 FPS at the format settings, you can't always get 60 FPS when your computer isn't good enough or your recording target moves slowly."
Especially because I know that my PC can handle heavy video editing and I have the same problem. So maybe it has been a waste of money to buy Bandicam.
Have you tried to contact their support department?

Did you try to play with MP4 format options? Bandicam saves into very small MP4 files, so its MP4 codec settings are optimized for faster encoding speed and small file size on a low end PC. It does provide some options though in MP4 output settings you can change. The codec may analyze input quality real time and optimally drop data that doesn't add much to output pic quality, for example when capturing static scenes. The numbers aren't everything, you need to compare MP4 video quality, and keep in mind file size trade-off.

You're forgetting that MP4 is a container and does not exactly dictate quality or size.

I never use(d) MP4 as I prefer AVI for editing. I've tried feeding it an almost stable 60fps source and the results were identical to AVI.

The framerate was correct and so was the playback. AVI container will show that it's 60fps even if most of the frames were dropped.

So the question here is... is the playback correct? If there's no activity on the screen then the duped frames can simply be dropped. Lastly, if AVI also drops a lot of frames (can be checked in such software as VirtualDub) then it's not a container issue at all.

Lastly, I captured a 1440p60 desktop/browser that was playing a 60fps video.

You're forgetting that MP4 is a container and does not exactly dictate quality or size.
I'm not OP, and neither forget anything. Your post complements mine, despite you try for some reason to make it look like you say something different.

Bandicam has on-purpose simplified GUI, and Video Settings show Codec MPEG-4 (i.e. container, while MPEG4 AVC - codec), with limited options to change. Your last capture shows frame rate variation 20 to 60 fps, and its
either codec or hardware controlled based on whether extra frames carry additional payload useful for the codec or on-screen video quality. It sounds normal for static scenes. Important is output quality, not merely the file media info. ;)

If the OP doesn't like the output file playback quality or file size seems to be too large, and he can't change it by limited codec controls via Bandicam UI, that may require some digging. Otherwise its largely irrelevant what MediaInfo shows for fps. Comparison video may help to see if any problem exists.

Any official support ? Ticket system ?

'm not OP, and neither forget anything.
The first line was directed towards your "Bandicam saves into very small MP4 files, so its MP4 codec settings are optimized for faster encoding speed and small file size on a low end PC".

The rest is directed towards OP.
And to OP again. You already got reply from the staff that the codec will drop frames if the screen isn't moving.
You can also e-mail them directly.

:roll:

Bandicam is primarily a GUI with some optimization presets. Encoding and multiplexing is done by installed with it or OS provided encoders you choose and muxer. It may be a good idea to offer some manual settings in the GUI for audio delay. Some playback software can't handle properly Variable Video Frame Rate resulting in audio syncing problems.

Why doesn't Adobe Premiere handle variable frame rate video? Bandicam may need a setting to record at constant frame rate, but it may increase recorded file size. Did you read this: Bandicam - Best settings for Adobe Premiere?

I also have some issues with Bandicam if you care to read the forum, but to be fare it offers a working trial with some restrictions not relevant to above issue. Why didn't you try it for your tasks before buying, and also do some web research (see above)? One work around that comes to mind is to record the game to RGB24&PCM, and than re-encode to MP4 with an external encoder.

Also, your language and the way to address issues pisses off other forum members. What I'd like to hear is Bandicam's support view on why it can record only with variable frame rate - any advantages and tech details?

Hi sambul,
agree with your kind of view - I have been stupid too :-( bought before visiting this forum - didn't find time to use trial version because of urgent job - wanted a fair price desktop screen recorder to use with my video editing program, PowerDirector 11, where my Projects use 50fps and PAL (Denmark). I'm producing my videose in m2ts files (mp4).
In future I might work with 4k and 3D videoes options which the program provides.
Still my problem is I can't get the MP4 files generated by Bandicam to Work in the video editing program even if I choose settings in Bandicam that match the editing program. If I managed to import the MP4 file Iget a frame rate conflict plus other problems, please see my former post.
just, all I want is some help to solve the problem so it will end with - happy editing :-)

Hi anja,

Miracles seldom happen. Bandicam is popular for lower size capture files it writes at lower CPU load. But it comes with a price - it seems to use older xvid encoder rather than H264 for MP4 files. If that was your priority at buy time, here we go. Other capture programs are available possibly more suitable for your task, but they may require a bit more research and involvement from you. Another solution for PowerDirector is given in this thread.

Of course you can ask the company to allow users select more advanced MP4 codecs in GUI, but H264 comes with higher CPU load, especially on older PCs without GPU hardware encoding acceleration. So if a user selects that codec, he may get slower choppy ride, and again start screaming "Bandicam is no more". :lol:
