I understand.

However, I wonder why you don't share Mediainfo reports of material you wish using without converting, but a file exported with Lightworks?

Ow I see apologies, I can show mediainfo for the clips before Handbrake, the last video I shot was broken up into small 5 minute clips whereas most of the time I might film a continuous 15-20 minute clip, does it matter if I just show one of the small clips mediainfo or would it need to be longer? Thanks again.

Mediainfo uses the time stamps of a few ten frames of MP4 and comparable formats to verify the frame rate mode (constant vs variable), but I'm not aware of any documented lower limit for media duration, but it isn't hard to find out on your side, just try.

Alongside with the mediainfo, please explain how the file has been captured/recorded.

Hi.

this is the mediainfo for a file prior to sending to Handbrake. I use a papalook webcam 1080p, I also use a Samsung Galaxy S10 also which films in 1920 x 1080 at 30 FPS.

Beside of performance, you won't be able to edit this material unconverted, without risking sync issues between audio and video. That's because it shows a non-standard frame rate of 23.942 FPS, which isn't supported. The closes standard frame rate is 23.98 fps(more precise: 24000/1001). In other words, even with your new computer, you will have to convert to a standard frame rate prior to import.

This might apply to recordings from your Samsung phone as well, because Android phones are know to create non-standard frame rates quite often.

I see, I don't mind massively that I will need to convert file FPS as a lot of things film in variable frame rates, my main concern was just if Lightworks would operate with the specifications mentioned earlier in the thread, again this could be subjective as every video is different and different sizes but wanted to check that I could do a simple video from the spec given.

I think the configuration you show is by far more powerful than your current Dell Inspiron 153000 and you'll see better editing performance with the same media. Also, converting media with third party software and creating proxies with Lightworks will be faster.

Just one point: Personally, I would add a second internal hard drive for backups and archives, 4 TB or above.

I would lean towards more memory, more storage and a faster, newer GPU.

16GB or more of memory, a 512GB or 1TB system drive and at least 8TB of media storage (it will fill up MUCH faster than you think), and on of the Nvidia RTX 2000 Super series cards.

Remember, though, that I'm a professional editor and I can justify spending more on some things because I can deduct them from my taxable income. For me it's more a matter of how cost effective is the extra efficiency I'm paying for than the initial cost of the equipment.
I work in Manhattan, USA, but at night I cross the waters to sleep in Brooklyn, USA.

Also, post production is not an afterthought!
