How do you compress a 700MB video to 300MB?

Answer 1

To reduce a 700MB video to 300MB, I would re-encode it with a more effecient video codec - H.265/HEVC, or AV1, VP9. These codecs can shrink file size by 50%. To compress furher, you can downscale the resolution, from 4K to 1080p/720p, lower the bitrate, etc.

The program I often use is VideoProc for it can compress video files with the least quality loss.

Answer 2

you can download a tool call Format factory. You can use it to compress your DVD disk into an mpeg , avi and many other format movie. It supports many, many formats including mp4, avi , ipods , psp, wii, phones and MORE.

Answer 3

You can use Winrar, Winzip or other file compressers. If it doesn't compress enough, try compressing the compressed folder one more time.
