General MKV question re. file size and compression
Posted: Tue Dec 20, 2016 5:42 am
I'm in the midst of re-organizing my collection of animated short films and I've come upon a strange circumstance that I'm hoping someone might be able to lend some insight into...
I've got several duplicate film shorts of roughly 7 min. lengths from different sources. I'm currently sorting through these to replace certain films that are incomplete or less than ideal (i.e. lacking original title and end cards, etc). While doing so, I've been able to "upgrade" certain standard definition films with new BD-Rips.
In analyzing and comparing the films, I've noticed that a 7 min. animated short in SD has a file size of 1.89 GB while the same 7 min. animated short in 1080P has a file size of 291 MB. Is this entirely the result of advances in encoding technology?
I'm trying to understand how an MKV file which is of considerably higher resolution can be so much smaller in size than one of much lesser quality?
This might sound dumb, but I'm almost hesitant to delete and replace the SD files out of paranoia that there must be some flaw that I'm overlooking.
I also don't completely understand how or why an MKV rip of a 7 min. theatrical cartoon can exceed 1 GB in file size; roughly the equivalent of a feature length SD-Rip, depending on encoding methods?
Can anyone please shed some light on this.
