I've been having lots of crashes lately (v19.0.2.58), during playback video suddenly stops and the program freezes, but sound continues until the end of the movie. Force closing the program and restarting works fine, until it crashes again after a few minutes. Anyone recognize this behavior, particularly that the sound continues playing?
Hi
In order to help you please provide all the information requested in your previous topic.

Here is my system spec:
AMD Ryzen7 2700X (no overclocking)
32 GB ram
Nvidia GTX 1080 (no OC, most recent Studio Driver)
ROG Strix X470F using onboard sound card (Realtek)
Samsung EVO SSD drives
Windows 10 v1809.
Using Movie Edit Pro Premium v19.0.2.58, video footage is 1440p 30 fps.
I have been experiencing random crashes before, but not this frequently.
Can you also tell us the exact format of the video files you are using? The mention of 1440 30fps suggests they may be AVCHD. This is a format which can cause problems for video editing programs because they are "compressed" and must be decompressed "on the fly" in order to play smoothly. Have you tried the option of Creating proxy (reduced resolution) files? These are used to smooth the playback in the editor but the full version of the file is used to create the export.
If you're not sure of the file format, the free MediaInfo will give you this information. Then you can post the results of the Text view here.

Hi
Thanks for the information.
. . . . during playback video suddenly stops and the program freezes . . . .
The issue you are having is most likely due to the lack of Hardware Acceleration (HWA) that Movie Edit Pro (MEP) uses to ensure smooth preview playback, particularly with video resolutions of 1920x1080 or greater.
The MEP system specs specify:
'Graphics card: Onboard, min. resolution 1280 x 1024, 512 MB VRAM and DirectX 11 support (recommended: Intel Graphics HD 520 for MPEG2/AVC/HEVC)'
As you can see there is no mention of support for NVidia graphics cards, from experience with a RTX 2060 MEP does not use the RTX for HWA of the preview monitor.
The 8 core Ryzen is probably running at 100% CPU usage and is struggling to ensure smooth playback with GoPro video, hence the 'freezing and 'stops' - the processor cannot keep up with the amount of data being processed to produce to achieve smooth playback.
Proxy files are the way to go in this instance. However if these are the 360 deg video files mention in your previous topic then you may still get some pausing during preview playback.
Another aid to smooth playback is to pre-render the sections of the timeline where the freezing occurs - how to do this is in the PDF manual available under Help do note that if you re-edit a pre-rendered section then the re-render will have to be redone.
