Reduce video size

[Chuckster]

Is there a software that can reduce the file size of vids and also replace the original file much like an Image Resizer can?

 

We have terabytes of vids and the majority could do with being reduced.

 

Thanks in advance.

I use prism. Download Video Converter Free. Convert 40+ video file formats.

I use handbrake https://handbrake.fr/

If you have that many I would script the conversion using ffmpeg.

 

I can post some examples if that helps?

That would immensely help if you could :-)

I've always used Nero recode, seems to do a nice enough job.

https://github.com/mavhc/shrink-video-recursive-python is my script to recursively search a folder you drag onto the .py file, uses ffmpeg and python 3. It adds a tag to the file to say it's been recompressed so you don't start compressing things again and again Edited March 20, 2018 by mavhc

+1 for Handbrake.

use this i use all time Freetime software and its free

[chazzy2501]

format factory is free, you can set batch jobs and quality settings.

 

it can also rip DVDs (not copy protected ones)

[ReadTheNetwork]

Must admit, not sure if handbrake would be able to handle it.

+1 for FormatFactory. It's amazing, but watch out for bundled tatware during installation.

I use XmediaRecode which is freeware:

Converts practically any format and can do batch jobs

[mavhc]

But which will identify videos that have already been recompressed?

[themightymrp]

Xmedia has the option to save back to the source folder and overwrite the original. So if you were to load up a list of files to convert, it will just progress through them one at a time. However there is no option to import files from multiple sub-folders all in one go, so if your videos are scattered across the drive it might not be too easy to build the initial list?

This is the script I use to find any file in a folder with a .mp4 extension and encode it to h.265 with mp3

 

find . -iname "*.mp4" -exec [b]ffmpeg[/b] -i {} -vcodec libx265 -acodec mp3 -threads 8  {}.mp4 \; 

 

I've been using it on dance/drama moderator video and crunched 1GB+ videos to tens of megabytes

try this one https://www.dvdvideosoft.com/free-dvd-video-software.htm ist free as well put can upgrade as well

[jthompson]

When using FormatFactory, I tend to run a Windows search for files that are 720p or higher (e.g. "frameheight:>700") and then drag all the results onto FormatFactory to create a batch. That tends to catch most stuff that I haven't already done.

Obviously, more detail search patterns can get more specific, or a scripted solution like others have suggested here could go a bit further.

Been using Handbrake here as well. I use the following settings if it is of any use.

 

Video Container = mp4

Video Codec = H.264 (H.265 doesn't seem to be worth the added encode time)

x264 Preset = Slow

2-Pass Encoding (makes a significant difference IMHO)

1080p Average Bit rate = 4000 kbps

720p Average Bit rate = 2400 kbps

480p Average Bit rate = 1600 kbps

 

This reduces iPad videos to about a 1/4 their original file size with out much noticeable difference in quality.

WinFF, although it's basically just a gui front end for ffmpeg

Hi Arthur,

 

I would be interested in some script examples. We have multiple ipad 1080P videos in multiple folders I would like to script down to 480P but save the output to the source folder. A bonus would then to be to delete the original 1080P version which will considerably reduce the size of them. Trying to get the PE staff to do this is just impossible no matter how many times we show them.

 

 

Thanks,

 

Alan.

This looks promising going to take a look

[FishCustard]

Here's a PowerShell script that'll use ffmpeg to compress MOVs during the small hours (you can obviously change the target file types and run time to whatever you want). Set a scheduled task to kick it off at midnight and it'll automatically stop processing files at the hour you specify.

 

I find that a CRF of 29 still results in more than good enough video quality. I target MOVs because that's what people dump off their iPads.

Drop then in Google Drive

@FishCustard this is working really well apart from when it runs again it finds the existing compressed file and ask to overwrite y/n which pauses the script? Any suggestions?
