PinballX 4.69 + Create Videos = Videos Playing Back Very Fast

[Tom Speirs]

Please try 4.70 and let me know results.

Hi @Tom Speirs

Didn't work, 0 byte mpeg created.

So, I went to another clean pc, installed latest PinballX and then FFmpeg I had, no video created at all. Then I downloaded latest version of ffmpeg and still no video created.

Here's the log file from the clean pc where I tried to create video for AC/DC.

Can you post the log file after trying to create videos (or is that it)? Ta

[TheProdigyUK]

That is it

[Tom Speirs]

That really cant be it. Its not even launching a game.

Hi @Tom Speirs

I relaunched and of course it overwrote the log, sorry.

I just re-installed the LAV Filters / CODECS, still creates fast video.

So, back on the Pinball machine, I have just re-installed the CODECs and created a video for AC/DC and still fast video for Backglass and Playfield.

Log.txt file attached.

From the log timings the duration of recording for the backglass video looks ok, so i suspect that is not speeded up  in playback(?)

For the playfield the recording went on a lot longer than 20secs. What refresh rate are you running the playfield screen at?, that may be a factor throwing ffmpeg out.

Hi scutters

Backglass looks sped up too. The main playfield is 60Hz and VPX is also set to 60Hz.

I just tried setting monitor to 75 and VPX and then re-recording but same fast video problem.

Can you post videos that speed up ?

Hi @Mike_da_Spike

There's two examples at the top of this thread  

Again:

Algar and The Addams Family

Sorry, didnt noticed the small link in the begin of your post.

I will try to set this up as well to check

I see you have an nvidia card, so you are able to use gpu capture as well.its not a solution, but a workaround 

 

[Tom Speirs]

In 4.70 and above, as another workaround just delete hardgrab.exe from the installation folder. This will force FFMPEG GDI capture.

[Mike_da_Spike]

I tried it on my test machine as well.
Recording in H264 results in a tmp**.mp4 of 0kb for playfield.
Properly because FFmpeg  tries to capture with H264_nvenc instead of libx264 (no nvidia driver/hardware on my test pc)
Recording on H265 creates files, but indeed playfield is twice as fast . Although the recorded video is 20seconds, it plays way to fast
Renaming/removing hardgrab.exe, results in a video that only has a couple of frames (total of 20seconds). Reverting back to 4.67 give me the same issue, so not a good test (or as @scutters says, its a crappy system :p ) 

If I have some time today (pretty busy) i will test more

Hi @Tom Speirs & @Mike_da_Spike

The Log file with Nvidia drivers if from the clean laptop which was just a test on another PC (other than my Pinball machine), so please disregard.

I deleted hardgrab.exe and now it works! I've recorded 5 videos of various tables and all are 'normal' speed, including backglass. Thank you so much for the workaround  

I'm going to leave it to do a bulk video creation of all my tables now.

If you get a code fix and want me to BETA test it then I'm happy to oblige.

Thanks again

Mark
