问题
I have done an iOS App Preview (Video) using iPhone 6 and Quicktime in Yosemite, but I cannot upload it for iPhone 6+ in iTunes Connect, and I don't have an iPhone 6+ Device.
Is there a way to make an App Preview (Video) for iPhone 6+ without the device ?
回答1:
I have found a good solution!
In Keynote app, I changed the document size to be the same as iPhone 6+ size and imported the iPhone 6 video and resizes it. I have resived the video to fit the document and exported it as a video. That's it!
It is not a perfect solution, but it is good.

Solution how to upscale video using iMovie 10:
Create screen recording using QuickTime player. As a result you will have a video with 1334x750 resolution (or 750x1334, depends on screen orientation).
Find any sample video with resolution 1920x1080 (or 1080x1920). It can be preview of some other application or any other video.
Open iMovie 10 and create new App Preview (File -> New App Preview).
Drag-and-drop sample (from step#2) clip from Finder to the timeline (first imported clip's resolution will be used in export)
Drag-and-drop your actual video clip from Finder to the timeline.
Remove sample clip from the timeline (you don't need it anymore, final resolution already set)
Click on
Select your preview project, Share Project -> App preview
You will see that export resolution will be 1920x1080 (or 1080x1920)
Success! I used this trick several times already.

Disclaimer: This solution only work for downsampliing, if you know how to upsample video please share it with us
Hi iphoner, unfortunately you need to record it using a higher resolution device and use Handbrake to convert your videos.
I used a iPhone 6+ to record the video using Quicktime and encountered the same issue.
To upload a video for iPhone 6+, you need to upload a video with this format size 1920x1080.
1) Change "Anamorphic" to "custom"
2) unselect "keep aspect ratio"
3) Set the size (width and height) you want (Warning u can only downsample it/ you need a large resolution as your base video)
Other device acceptable formats:
ipad: 1200x900, 900x1200
iPhone 5.5inch/iPhone 3.5inch: 1920x1080,1080x1920
iPhone 4.7inch: 1334x750, 750x1334
For a more comprehensive guide please refer to this document by apple

You can generate the video from the simulator by running through the following steps.
- Get your app running in the simulator.
I believe you will need to run the simulator at 100% scale to ensure 1080:1920
Open up Terminal and run the following command
$ xcrun simctl io booted recordVideo /path/Video.mov
Switch to your simulator window and run through your demo
When you have finished your demo switch back to your terminal window and Press CTL+C to stop the recording
Edit the movie in iMovie
- In order to upload as an App Preview then it will need to be < 30 seconds. You can cut the video down a little, or speed some sections up in order to get it under 30 seconds.
- Once you have finished editing the movie you can then export it (File->Share->iTunes)
This will save it to your iTunes library:
/Users/marcbeavan/Music/iTunes/iTunes Media/Home Videos/This file is ready to be uploaded to iTunes Connect
File info for my video is shown below

I make a lot of app previews and in all sizes. The easiest way is to have all the devices, but that's definitely not practical for most people. You could also edit the dimensions post production to "simulate" the actual device, even iPad. I would also recommend avoiding the problem all together by having someone like snappdemo.com do it for you pretty cheap.

This command line works perfectly for me every time. It comes from an answer to a similar question (link):
ffmpeg -i input.mp4 -acodec copy -crf 12 -vf scale=1080:1920,setsar=1:1 output.mp4
It will take the input.mp4 file, resize it and output ouput.mp4. You need to install ffmpeg before running the command.
Of course, upscaling leads to quality loss. But if you do not have a Plus screen, this is much better than not having a video app preview at all.

If you have any way to record higher resolution, like an iPhone X and need 1080*1920, just follow these steps:
- Open your higher resolution video in Quicktime.
- Go to Edit -> rotate right.
- Go to File -> Export as -> 1080p.
- Open exported File in Quicktime.
- Go to Edit -> Rotate Left.
Worked great for me.
