Testing fullscreen video capturing @ 60 FPS

[UEZ]

Can someone with a 2K+ monitor test whether screen recording works at 60 fps? The previous version used the GDI API to send frames to the codec, which is too slow at high screen resolutions. Windows build 18362+ required!

Link to: ScreenRecorder2_vfw

Please unzip the 7-Zip archive and run one of the executable files. Recording will begin on the main screen as soon as the CMD window appears and a yellow rectangle is displayed.

 

Please run “Configure_x264vfw.cmd” (default is the x64 DLL version), adjust the settings according to this screenshot, and then click “OK”:

Once the recording is complete, the “Actual Time” should be roughly equal to the “Target Time,” which is 15 seconds (900 frames).

 

Can you please post your screen size and the “actual time”?

My result:

1920x1200

Actual time  : 15.01514229999849 seconds

 

The closer the actual time is to the recorded time, the more accurate the recording was.

 

Thanks.

@AndyG Were there any problems with the player? @Danyfirex reported problems with VLC Player playing AVI file.

It does work but before play with VLC it says this:

Should be fixed now - you may try it again. x64 should work - x86 may have some issues and may crash!

 

Btw, I renamed the GraphicsCaptureWrapper DLLs and record time is now 20 seconds. You don't need Ultrafast, Superfast should be ok, too.

Hello. X64 works fine for me. But for x86 I just get this.
 

It just exits after one or two seconds.

Saludos

I had no trouble playing the .avi file with the windows media player, It doesn't matter whether it's x86 or x64 (Win11 pro 24H2)

No video problems with Cyberlink PowerDVD Player, IrfanView (x64) , MS Clipchamp, Winamp....

Thank you both for testing. 👍

@AndyG my previous version is ok for x86 because I didn't use threading. With lasted update I changed it to threading, ergo encoding is executed in a separate thread but for some reason it doesn't work for x86. Actually I cannot find the issue - maybe VfW‑Thread‑Affinity‑Problem under x86.

Both are working perfect to me already

Salut UEZ

With the desired settings ,

And no problem for read video with VLC, except the reading speed which is 2 times faster
I saw my desktop Clock changing second too fast

@wakillon thanks for testing. vfw is now replaced with x264 dll.

 

@All:

Can you please test: ScreenRecorder.7z

 

It is now GUI driven. Limitations: 2GB AVI file and Windows10+.

You're welcome 😉

 

First problem, your graphical interface is hard to read as if you were using transparency

Second problem, If there is no user activity the  duration of the video is almost the same as the real duration, but if i open and minimize several windows while recording, your display timer is late ( example 1m42 for 2 min recording)

 

[Gianni]

I recorded for about a minute just by pressing the Start button and without changing any settings, but when I open the file, the media player displays this message: "Cannot open Capture_..._... It's using unsupported encoding settings." (win11 x64)
Am I doing something wrong?

Yes, I can reduce transparency. When the background is dark it looks nice but on brighter background it becomes harder to read. Let me check if it is possible to get the recording time rather than a parallel timer.

Obviously Windows cannot play AVI file because of missing decoder for H264 - MPEG-4 AV (part 10) (h264) (same on my Win11). You can use VLC Player, MediaPlayer Classic or any other app which supports this codec.

 

Thanks for testing. 👍

 

Btw, defaults are 30 fps and Region doesn't work properly yet because of some unknown stride settings...
