Reduce file from 16GB to less than 5?

newmexd ha scritto il 08.06.2016 ore 03:17

Hello, can anyone please give me some suggestions to reduce my video to les than 5GB but retain quality? I am using MAGIX Movie Edit Pro 2016 and have a 1:45 movie that I am exporting with the standard settings for MPEG4 1080 29fps. This video will be a product I am placing on my website that my customers will have the ability to view online or download and the file size as is, is at 16GB! Too large for anyone to download.... I read that full length HD movies from Itunes are less than 5GB. It takes me like 5 hours to export so any suggestions would save me a whole lot of time playing with settings.

THANKS!

Devon

Hi,

To export a vidéo on your own website use custom parameters, my standard quality is mp4, progressive, codec H.264 and the size for HD is 854 x 480p and bit rate is between 200 to 500 kbs, if you need more quality for TV may be an iPad with Apple TV viewing use 1280 x 720p and use a bitrate to accomodate your quality if you use 5000 to 6000 you jump at 40Mb per minute if you cut the bitrate you cut in MB and quality.

If your video is made you can use a video converter to reduce the size and the bitrate. In 2 minutes you are ready to upload. I just start a new website and all video are 854 x 480p and the first video on Home page is about 1 MB per minute. Check this on www.protuto.com

. . . . suggestions to reduce my video to les than 5GB but retain quality . . .

On my websites I reduce the resolution to 720p for playing fullscreen, there is very little reduction in quality compared to the large reduction in file size.

See this post for the settings which you can save as a Custom export preset

If the video is played in a confined player ie I do not what them played full screen then I reduce resolution down to 480p.

I also create OGV and WEBM versions to cater for mobile devices.

Thanks! My problem is not with the posting of the video. I can reduce size for online. My issue is with the downloadable version for my coustomers. I want full HD and read that there is not a huge file reduction when going from 1080 to 720? Full HD movies from Itunes seem to maintin HD quality when viewing full screen but file sizes are less than 5GB. With mine currently at 16GB, I don't see how going to 720 will get me to under 5GB? Maybe going to 720 and then using a video converter to get the file size smaller?

Uptade: Exported the same 1:45 video as 720*480 and got 15GB file size!!! This is not making sense to me...

In my experience, the video dimensions eg 1280x720 or 1920x1080 has no bearing on the MB size of the file. The only thing that affects the MB size of the video is the bitrate. The dimensions of the video may/will have a bearing on how it displays for the user eg VLC Player can be set to display "actual size" verses "fit in the window". Obviously, with the same bitrate, the bigger the view, the lesser quality. That's why videos on phones look so good; they have all that datarate squashed down into a small viewing screen.

So, wind your video bitrate down. You should be able to get it down to around 2,000kbps using MP4 format. That'll give you a file size of around 2gb for 1hr 45min. As well, set the dimensions to suit your viewing audience. For a PC/tablet, use 1280x720. If you want to make a phone version, you could wind the bitrate way down to 800kbps and still get reasonable quality.

Experiment with the bitrate by exporting say 10 minutes of your movie. Then when you're happy with the quality and size for the 10 minutes, extrapolated to 1:45), export the whole thing. Nothing worse than waiting 5 hours and it doesn't work out properly...
