File sizes and codec help

so i am currently planning prequel edit of TPM AOTC and ROTS. i have already almost completed my AOTC edit and i am going to be working on TPM. however, the file i am working with for this project is KK650’s regraded version since he has color corrected and added film grain to it (which saves me some time). this file is 22gb and to edit it i have to re-encode it with Lagorith Lossless codec, which will make the file size bigger, but i am not sure how much bigger it will be though. the version of AOTC that i am using is KK650’s as well but it is the 8gb version so after the LAGS encode it was only 70gb, which is manageable. but a 22gb file is going to be well over that and i am worried that i may run out of space. my only option is to re-encode the 22gb file with an encoder where i can control the file size, and then re-encode again with LAGS.

i guess my question is, is there a way to find out about how big 22gb file size will be after encoding with LAGS?

Is the 22gb the same res as the 8gb? If so, the Lags output might be similar at around 70-80GB. Don’t bother with encoding that down and then reencoding that with Lags, as the final filesize will probably be the same, UNLESS you apply some DSP such as: denoising, colour reduction, which makes the frames easier to predict.

Right. If you’re going to be using these as a source for anything, use the 22gb versions and not the highly compressed 8gb one, because the lagarith encode will be roughly the same size.

If you’re only making a few small edits and have a decent machine, you can import the 264 streams from KK650’s release directly into editing software like Adobe’s. If you’re going to do something that has hundreds of cuts, different sources, and lots of effects applied, things will get bogged down and you’ll probably want to go the lossless route.

im not sure about the res (i am assuming you mean resolution?). they are both 1080p, so i dont know if that is what you mean by res? but that would be awesome if the file size came out to be the same.

how exactly would i go about doing this (importing the 264 streams)? The file is an MKV

i am planning on putting these edits on a DL DVD at the highest quality i can

What are you using? Premiere? Just demux the mkv using something like tsmuxer. It’ll give you a .264 file that can be imported into premiere.

That’s what he means by res, yes. If you take an 8gb or 22 gb and convert it to a lossless format, of the same resolution and duration, it’ll end up being roughly the same size. Though lagarith is compressed (but lossless) so difference in artifacts and grain from the two sources might have minor effects.

great! that is good to know. i was really worried that i would have this 500gb file and no space on my HD to edit. thanx Towne
