Resulting file size

[Hattie]

I am tidying up some old home videos.

Would anybody have any advice to try and maintain the file size to nearer the original file size?

Openshot 3.3.0
windows 10 PC

They were shoot on a tape camcorder in the '90s
transferred to dvd then ripped as a .vob files to my pc.

i used Handbrake to trim off some interference from the edges of the videos and convert them to mp4 files.

I have used OpenShot to add a title and a "The End" screen (5 seconds each).

but this has increased the resulting file size a lot from 251 MB to 980 MB

I have tried using different profiles but the resulting file size doesn’t change by much.
converting them from 720 to 1280 doesn't make much sense so i tried some 720 profiles - didn't make much of a difference.

I don't want to upscale them - it just happens!!!

Obviously, it will be a bit bigger because of the extra bits I’m adding but this is only another 10 seconds of title screens.

I did put one through Handbrake again with the picture size set to 720 and this reduced the file size to 110 KB which seems a bit too small but eh video quality seemed ok, lower data rates but it looked ok.

Obviously, the original was not a high spec. to start with so converting it to 1280 is not going to increase the quality so seems pointless.


The original MP4 file is 251 MBytes in size (from the vob file)

frame width: 718
frame height: 566
data rate: 1060 kbps
total bitrate: 1320 kbps
frame rate: 25.00 fames/sec

When I encode it in OpenShot the file size is 980 MBytes

frame width: 1280
frame height: 720
data rate: 4992 kbps
total bitrate: 5121 kbps
frame rate: 25.00 fames/sec
