Does anyone know how to fix this problem? "Could not initialize the playback engine for sequence" I was editing fine yesterday but today I have this error. Repairing Hitfilm did not fix it and deleting and reinstalling also did not work.

    First of all, Win 11 is not a currently supported OS for HFE (I assume you are on Express). And I believe your laptop's integrated GPU might be under spec? Even though you may have a "new" laptop that doesn't mean it has the beef to be a video editing machine.

    Integrated GPU's are often allowed to steal regular machine RAM and use it for VRAM since they often have little if any of their own. Since you only have 8 GB that could cause issues if the GPU chip gets hungry for VRAM. This results in stealing RAM away from the OS and other applications.

    Also, make sure you have downloaded the latest version of HFE that contains a patch for media handling (Version 2021.3 (PATCH #2)) :

    However, running under Win 11 is still problematic.

    In addition, more information on the video file would be helpful. Please list a MediaInfo text report on it. How to use that here.

    Could be that the video file is wonky and you may need to transcode to something more standard. If you don't already have it, get a copy of Handbrake. Try transcoding the video and see if that helps. How to use Handbrake here.

    Thank you! I think Windows update may be the problem then because my Hitfilm worked fine before the Windows 11 update even with the 8GB RAM. Will try to get an older windows and see if it works properly.

    As Stargazer has indicated, should be editing in constant frame rate, so say, 29.97 constant for your clips, and set the timeline to the same, but it may be by the looks of previous comments here in this thread, you may be a bit under spec, though in this case, the latest version, if that's what you have for HF, be it Express or Pro says you can use the Intel graphics from 2016, or greater, and you have a later processor so you may be OK, but again, if you ARE using the latest, then you may be OK with Win 11. Older versions were not built with 11 in mind, that means 2021.2 and earlier variants.

    Also, be certain you are not using the drivers from Windows as they may not be the absolute latest versions, best to go to the source of your graphics card, in this case, Intel to ensure you have the latest, and agree, best to up the memory to 16GB, at minimum. .

    Read here on how to update the GPU - https://fxhome.com/faqs/view/10

    As @littlehausbigcity said, you want the drivers from the manufacturer (in this case Intel) and not from Win updates.

    I went back to an earlier version on Windows 11 and hitfilm works properly again.
