    Good day,

    Yes, I find this funny myself.

    I have a total of 13 video files, I will edit them using Final Cut then I have to compress all that to 50MB so I can upload it to a website as a memory of a person that died. That website will only accept 50 MB for the video file and only 1 file per "profile".

    Of course, I will cut a lot of stuff.

    I would like suggestion regarding what software I should use to compress my video.

    Thank you very much

    Why not just use Youtube for the video? Far more freedom, and less need for cutting things out. Plus if you want to include textual information (a profile of the person), you can just add that into the video when you edit it in Final Cut.

    Compressing a 1GB video into 50Mb is going to yield horrible results.

    So, in short, I'd find another site that accepts larger files, or Youtube.

    You can use Dropbox to host the video file in the "Public" folder which will give you a public URL on the web for the video, although it's pretty uncommon to link directly to a video file.

    It would probably be better to use YouTube or Vimeo. They both have privacy options you can explore with a test file such as the ability to hide the video from the general website and search functions. This is called "unlisted" video on YouTube.

    No need to be limited by 50 MB for video in 2015, there are many options

    Have you looked at other videos on the website?

    I can't help with the software side except to suggest the old standard, Handbrake.

    The reason I ask about having looked at other videos is this will allow you to gauge what resolution is suitable and length: according to Wikipedia, bitrate for h.264 480p YouTube video is about 1 Mb/s which would give you a 400 second video. Not much for a lifetime but you'll have an idea how much cutting will be needed, assuming you haven't already done the editing. Perhaps including some stills will allow you to stretch it a bit?

    If you're unhappy with the low res video, trade off will be length. It really is that simple.

    I think you already know that you won't be uploading 1080p Blu-ray DVD video (MPEG4 is 40 Mb/s according to same article) and that it won't be very long so perhaps that 1 GB of video can be cut down pretty quick.

    Ps: condolences if this was someone close to you

    Thank you. He was close.

    It's now a 2,5 minute video file but is 2GB. I have to bring it down to 50MB and I definitely understand that there will be quality loss but this is only for the family to see online.

    A 2.5 minute video should be able to fit in 50MB. Try encoding it in a high compression codec like h.265/264. I don't know much about video encoding, I clicked the link because of your title. I have seen 2.5 minute videos at 50mb or less, though.

    It sounds like your video is uncompressed ProRes.

    Try converting to 720p H.264 video using HandBrake; if it doesn't get down to 50 MB try again with either a lower resolution or fixed bit rate (I believe this is possible but I haven't used it in quite a while).

    I routinely post smaller mp4 files for the bandwidth disadvantaged. A 2GB QT Mov file (what you get when you share a master video out of FCPX) will compress into a good looking 960x540 file of 70MB. ~50MB may not be much of a stretch, but you will have to fiddle a bit. I use Apple's compressor to create the mp4 file as it does a good job, but handbreak may work well enough. When I want to squeeze the most video into a file I use handbreak, but quality is sometimes pushing it. There are also FCPX presets to play with, although some of the presets result in very small dimensioned video. In years past, I've easily squeezed 30 minute clips into 250MB for SD home movie DVDs. Just saying that 2.5 minutes into a 50MB SD video its not completely unreasonable. It'll look great on an iPhone or iPad, probably no so great on a 60 inch screen :).

    Sorry for your loss

    Thanks everyone, I was able to fit 2,5GB mov to 25MB mp4 with a free software on the app store, forgot the name and I'm on a PC... right now hehe!

    Nice to hear, I didn't think you would have a problem. I routinely use the free handbrake app to compress 20 minutes of SD video (5GB) down to a 200MB file that plays nicely on appleTVs (better than DVD quality). True HD video takes a bit more space.
