How to Improve your home videos
1 Open your video Open Video-Grade, tap Start Editing and grant access to your photos. It’ll find local and shared videos. Tap an album to see its videos with their durations and resolutions. Tap one to open it. (If it’s in iCloud, there’s a wait while it downloads.)
2 Test the video Tap the Exposure filter (bottom-left) then drag the thumb on its slider to adjust this attribute. When done, tap the tick (top-left), then Export. If this fails, use the Dropbox method from the intro to transfer this video clip to your iPad.
3 Choose a frame You can pick which frame is shown as you try out changes. Tap the video navigator icon (fifth down on the left), then drag the video strip to pick a frame. Note the tools at the bottom left, which allow you to trim your footage at export.
4 Adjust sharpness Older, low-resolution footage can benefit from being less sharp. Select the Sharpness filter (a hollow triangle), then drag the slider’s thumb left. Low-light videos can benefit from a sharpness increase – move the thumb right.
5 Remove colour casts If your footage has a colour cast (blue is common in snowy shots), tap the Channel Mixer icon (three circles), select the relevant channel, and very carefully adjust the sliders to make the colours look more natural.
6 Improve lighting Outdoor shots can be washed out. In the Temperature filter (a thermometer) tap the sun icon. Next, in the Recover filter (a plaster), reduce highlights. Finally, tap the crayons icon and boost saturation slightly to make colours more vivid.
7 Get creative Some footage will be too low-quality to rescue, but you can still make it interesting. Try using the Monochrome filter (the chequerboard icon) and Effects (the photo icon) to turn grainy footage into charming black and white or sepia.
8 Save and preview If you make a lot of adjustments, save them as a preset (tap the fourth icon down on the left) in case something goes wrong during preview or export. To preview your work, tap Video Preview (the play icon, fifth down on the right).
9 Compare and export At any point, see how your effects compare with the original look by turning on a comparison preview (the third and fourth icons down on the right). When you’re happy, export (as in step 2), ideally at the original resolution and frame rate.
