Hello, I wanted to make this a quick thing but problems cant be avoided.
I wanted to make a quick video for Youtube containing pc screen record of a game ( importing works) and a phone screen record. After trying import the phone screen record my lightworks freezes and crashes. Pc game recorded at 30 fps, flv but converted to mp3 with yamb and flv extractor.. Phone screen record is set to record at 30 fps but on mediainfo it says 13.492 fps.
Now posting all the mediainfo information about the phone screen record video.
Thanks in advance.. I dont know where to ask for advice.

Hello and welcome!

"Something.mp4" shows a non standard frame rate 13.492 and a variablity which I've never seen before.

Frame rate mode : Variable
Frame rate : 13.492 FPS
Minimum frame rate : 0.993 FPS
Maximum frame rate : 106.132 FPS

What device and software has this file been recorded with?

You conveted a flash video file to the audio format mp3, does it contain only audio? If that's a typo and you mean MP4, would you mind posting mediainfo of the original .flv file?

I recorded it with Screen Record software build in my Xiaomi Mi Mix 2.
But that phone screen record video I didnt convert. I only converted the pc game record but it is fine.. I tought it would be fun to do a little recording editing and posting on youtube but it seems not the case here

You could try converting the flv with Handbrake, ensuring that it's set for a constant frame rate.

There was another recent games recoding which had an extreme frame rate variation, it had an even higher top frame rate. It ran into difficulties when tried on V14.5 beta.

To stay away from further future trouble with your workflow and devices, I'd suggest using this procedure to transcode to MPEG2 I-Frame HD format using Eyeframe Converter

Please specify 30 fps for both recordings explicitly when converting and use a 30 fps project for editing (not mixed rates, not 24 fps).
