Batch splitting many video files into smaller parts

[manav]

Hi,
I have about a thousand .flv files, the size of each of which varies from 1 GB to 11 GB. I don't want any file to be bigger than 512 MB, and thus, I would like to split all of these files into smaller pieces, without any re-encoding. Is there any tool that allows me to do so?

What I would like to do is select all the files, enter the size that I want each part to be of (512 MB), and just batch split all of them in one go.

Below are the details about one of the video files:

What is the reason for the split?
Do you want independently playing pieces, or do you simply want individually sized pieces that can be later recombined into its original self?

Thanks for taking the time to reply. The reason is that these files are huge live streams, downloaded using Streamlink. I wanted all the parts to be playable independently. I am constantly uploading these to a cloud storage service called Degoo, which doesn't allow its free users to upload files larger than 512 MB. In addition, having smaller and equal sized parts makes it easier to organize them and to find any specific part from the downloaded streams that I am looking for.
I have already found a solution in another post.

You can use mkv merge. Just add in the file size for the split.

You'll have to split them on keyframes if you want to avoid re-encoding. And that means they very likely WON'T be the exact same filesize, as it will be content- (read: bitrate) dependent.
