Every 5-6 seconds the cpu spikes and frame freezes. For imported media the "make proxy" menu is greyed out.

system is a Ryzen 2400G with SSDs and quiet capable of playing 4K footage with low cpu.

How to fix this?

Thanks

Trouble Importing GoPro Hero 4 Silver Footage - by: mlee11 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=197771&Itemid=81#197771 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=197771&Itemid=81#197771
I've attached my MediaInfo report of the file. The rest of my videos from the same camera (a decently old GoPro Hero 4 Silver). This isn't a vital clip to my project, which is due tomorrow (procrastination is killer), so I just want to learn a little more about the software and how to prevent this in the future. Thanks!]]>

Issues with DV Avi (corrupted sound) - by: AlexShemp https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=197440&Itemid=81#197440 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=197440&Itemid=81#197440
apologies if this has been answered, but I couldn't find anything via the search function.

I'm currently testing the free version. Mainly I want to edit my transferred (Mini-) DV files. I presumed that LWKS doesn't support type1-DV (because it won't import it), so I transferred some files to type2-DV. These work flawlessly in Avidemux. After importing them in LWKS, however, the sound is a mess, probably sped up or something to that effect. My project settings indicate 48 kHz and that should match my imported video.

Edit: I should add that I'm using Linux Arch.

Here are the specifications of my test file:

Video turns black, but you can still hear me - by: BalchDk https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=197246&Itemid=81#197246 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=197246&Itemid=81#197246
I would like to have some background music and then have the video texted, so hope to find a solution to that SMIL from Denmark]]>

Is There a way to transport a video that you are still editing on another computer? - by: 20008815 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=197148&Itemid=81#197148 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=197148&Itemid=81#197148 Codecs / Importing / Exporting / Transcoding Mon, 06 May 2019 15:36:03 +0000 Cannot import videos - by: jadach1 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=197112&limit=15&limitstart=15&Itemid=81#197112 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=197112&limit=15&limitstart=15&Itemid=81#197112
Even though the file is listed as 30FPS and is about 8GB large and I can watch it however, Lightworks will not recognize the file and hence I cannot import it.

I have attached 2 screens to show the file description and what is shown when I try to import the video.

If anyone can please help solve this issue that would be great.

Thank you.]]>
