taking one frame at a time since 1999

Hello. I was wondering if someone on here could help me with my PC specs for editing RAW image files for my new Stop Motion. So I recently upgraded my PCs Motherboard and Processor because I thought I needed a new Processor to help make editing RAW image files easier, but even with my new processor my PC still struggles to play back the pics in the editing software. It's so laggy that I basically can't edit. Can anyone on here tell me why this is? Do I need an EVEN better Processor then the one I just bought? Are RAW files just to big to edit with? Am I doing something wrong with my settings that's making it hard for my PC to handle it?

The Processor is the Intel Core i7-10700 Comet Lake 8-Core 2.9 GHz LGA 1200 65W BX8070110700 Desktop Processor Intel UHD Graphics 630

The Motherboard is the MSI B460M PRO-VDH WIFI LGA 1200 Intel B460 SATA 6Gb/s Micro ATX Intel Motherboard

I have 16 gigs of RAM 

I edit with Vegas Pro 18.

Thanks :)

Someone who uses Vegas on a PC will probably know more about this.  But I think Raw files at 16, 18, or 24 megapixels (water your camera resolution is) are probably just too huge for any computer to play them at video speed.  Have a look at the file size of an individual frame.  

None of my video or image editing programs actually work directly with Raw files anyway - when you import them into After Effects/Photoshop a window pops up where you can adjust the brightness, contrast exposure etc, using all that extra information in the raw files - then it imports them as uncompressed image files that it can work with.  But even then, there is a lag of a second or two when you advance from one frame to another.  It can play a very pixilated low res preview so you can see the movement, but not the details.  (This is on a 2013 iMac with 3.5 Ghz quad-core i7 processor and 32 Gb of RAM.)  

I don't normally load my full size DSLR images into my video editing program (Final Cut Pro 6 or Da Vinci Resolve 17) either.  Even if they were shot as Large Fine Jpgs, they are 5184x3456 pixels, which is too big, and the wrong shape for video.   After doing any green screen keying, rig removal, or other fix-ups in After Effects or TV Paint at full size, I scale them down to 3840x2560, then crop the top and bottom so I get a 16:9 ratio, 4k 3840x2160.  Usually I scale them down again to HD 1920x1080, as Lossless or Apple Pro Res mov files, before importing them into my editor.  And it can play those smoothly.  

So i would expect Vegas on your PC to handle HD 1080 video perfectly well, and maybe 4k video too.  If it is a couple of generations later than my processor it might manage a bit bigger.  But I didn't think any editor would actually load RAW images, keep them in that format, and be able to export them as RAW.   If they are not still RAW files once they are in Vegas then it must be just the size of the images that is too much to handle.  Let's hope a Vegas/PC user can jump in here with some better information.

 What software do you use to lower your images to 1920x1080?

I have no experience of Vegas and I use a Mac, but it seems to me that what you need is proxies. These are small video files that enable you to edit easily. They should be linked to the big RAW files so that when all is completed, you can export from the RAW files rather than from the proxies. I know that Davinci Resolve has a system like this.

This is effectively what Nick was talking about although he didn't use the term proxy.

I just went ahead and am preediting my pictures in an other program and shrinking them from 25mb each to like lees then 1mb. That seems to be working.

Christian - I use a fairly odd program to do my re-sizing and cropping, and a lot of other post production tasks.  It is a  French 2d animation program called TV Paint Animation.   It is more like Photoshop in the way it works than Adobe's After Effects is, except it is designed for working on a sequence of images in layers rather than a single image at a time.  The main exception is that I use After Effects for green screen, and after keying I sometimes reduce the size in AE as well before saving the sequence.  But I decide exactly where to crop the top and bottom in TV Paint.  I use it because I've had it a long time, since it was the nearest equivalent to Photoshop on an Amiga computer, don't know that I would recommend it to someone who has to learn it from scratch, there are many alternatives. 

Simon - I am not actually editing with proxies, as far as I know.  Or am I?  I load 1920 x 1080 QT mov files in Apple Pro Res HQ codec into Da Vinci Resolve, set the project size to the same format, cut the shots together and do a bit of colour grading, then export a single mov file of the finished film in the same format.  That seems to be well within Resolve's capabilities. (Or is Resolve actually working with a smaller resolution, but referencing those HD files when it exports?  It does need to do a Render so that would make sense.)  i don't think I could reference the RAW files in the edit.  My RAW files have not gone through the wire removal, compositing, or fix-up stages, since I don't know of a way to work directly in Raw format and save changes as Raw files.  But I could reference a higher res finished version of each shot.  For my next project I may decide to make a finished master of each shot in Ultra HD/"4K" 3840 x 2160, and if that is too much for Resolve to play smoothly I will edit with proxies.  

I am basically doing something like that now Nick. Thanks for the help everyone!

Nick -sorry just seen your reply. I am far from an expert, and seem to have to remind myself why to do each time, but the principle I think I am trying to adhere to is to render as few times as possible, ideally only once. DR seems to allow one to bring in large JPEGs, process them through Fusion (which works on the originals, not on a 1920 X 1080 reduction), edit and colour grade before exporting just the once. This should maintain the maximum quality. The different workspaces -Edit, Fusion, Color etc do not operate sequentially, so an effect done in Fusion can get seen in the Edit page; this would seem to mean that one can trim a shot to eliminate having to remove rigs from frames that are subsequently cut, then do the rig removal (at full original resolution), then go back to the Edit page and continue....

Because it can be difficult to view the stack of JPEGs in real time, opting for proxies or optimized media plus reducing the playback quality allows the editing page to give a smooth playback. Then when it is rendered out at the end of the whole process, it is possible (but I haven't yet tried it) to export at ultra HD or HD, because the render process finds the original images and renders from them, not the small ones used for editing convenience.

I am mostly using large fine JPEGs as the RAW files are so huge, but at least in theory the DR process should be capable of taking in and processing RAW files. Should probably be using RAWs.

Take a look at this video - it explains how to setup DaVinci Resolve to use the proxies. Or in other words, how to edit your raw material, without crashing all the time.
