We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

Free video compressors, which work to output file size? (alien.top)

I currently use Handbrake to compress oversized video files. It's very good, but I find myself having to run a few test outputs to find the best balance between size and quality. But, maybe that's just best practice anyway.

I would like to have a function where you can specify an output size (plus a few other parameters), and it just does the rest. Freemake Video Converter has a pretty good interface and does this, but it requires a subscription.

Can anyone recommend any good free video compressors for Windows, which have an output size option?

If you know the play time and the size you want, you can calculate the total bitrate you need to set. Subtract the audio bitrate from the total, and you get the video bitrate to set. Make a spreadsheet and fill in the numbers.

Depending on the contents and aspect ratio, you may get bad results. Setting a lowest acceptable quality is better, but then size can vary a lot.
