Resize and combine lots of videos

Brooklynite 4,725 615 January 2, 2016 at 07:23 PM
Hi there,

Can someone please help me find a software that can take like 150 x 1080p videos that I have taken with my cellphone, during 2015, and combine them all in one video files, sorted by date, compress in h.265, and reduce to 480p and save it to disc as a single video file?

Just to compare, Irfanview does a perfect job doing the exact same thing with images, but not for videos.

Edit: forget about my silly idea, seems HandBreak supports h.265 now.

i don't know any converter.
but PotPlayer can record VP9, in real time, not good if lag, but can pause. can mute in system, minimize to do other things. bad idea if the length of that 150 videos are too long.

playlist should be ok, but if want more smooth, i like to combine with tsMuxerGUI

higher compress codec better at high resolution, maybe set to 720p at same bitrate?

i don't like single file, harder to seek.

I'm guessing a lot of these videos are fairly short. The best option is probably to feed them into a proper video editing program and sort them by date and drag them onto the timeline. Edit as required and export. I'd export 1080p and then convert that down to 480p.

Here are two free video editing programs:
http://shotcut.org
http://www.lwks.com/ *free version can only export up to 720p

If you want something more basic, you're probably looking at command line scripting of ffmpeg or similar. This might not be easier than a video editing program.

You can use handbrake or adapter to convert the files

I'd agree that you should look at this as a two step process: Combine the videos using video editing software at a high bitrate, then resize / reencode using something like handbrake.

This can be done using ffmpeg using the convert filter, but the command line syntax is a pain in the *** (you need your shell to spit out -i -i ... -i, unless your files match a very specific naming structure). I could tell you how to do it in bash, but I actually don't know how to do it in a windows command prompt.
