Uploading Large Media Files
If you try to load a video or picture into your WordPress blog using the Media menu, you will find that you can only do files up to 64Mb.
So what do you do with larger files?
First lets get the file in there before worrying about the rest.
Next you have to select the directory where your files are stored, don't worry it points you to the default directory so unless you have moved the files this will be right and you can just click on the OK button.
Once inside that directory you are going into the year directory, again double click to get you to the months directory where you want to select the current month. When you get in here you are ready to upload your file.
Uploading the file
There you have it a large file unloaded into your media directory. The only thing left is to let your post / page know where it is. You need to record where the file is and what it is called so you will have the URL of the file. This will be something like - http://YOURDOMAIN.COM/wp-content/uploads/2015/01/FILE-NAME.JPG you are going to need this when using it in your post.
Using the file in a post.
From the main post screen click on the Add Media button this will take you into the load media screen.
When this is loaded you will want to enter the address of the file you uploaded in the space provided and click on the Insert in Post button at the bottom.
What to do with video files?
Some times we need to in-bed a video on a post or page, so how can we do that with a large file. Again you follow the steps to get the file into your media library and then you use the shortcode
You can change the width and height to suit your video and theme. Now you have the video in your post or page.
That is that you now have a large file uploaded to your media library and positioned in one of your posts.
