iOS 应用预览视频未保存在 iTunes Connect 中

Question

I created a video of my iOS game using quicktime, processed it & exported it with iMovie iOS App Preview settings. Though I'm able to upload the video to iTunes Connect and successfully play it there, could select poster frame but it says " Your file could not be loaded, try again " & when I save the page, the video doesn't get saved.

I recorded in iPhone 5C at Resolution : 1136 × 640 @ 30fps, Codecs : AAC, H.264, Duration : 0.29 seconds.

I had already followed the handbrake and other approaches mentioned here - Unable to load app preview in iTunes connect but in vain.

Please let me know if there's any sure shot method of uploading App preview video.

Answer 1

I experienced this problem too and ended up by using free app called HandBrake to re-encode my mp4 video with specs described in the developer.apple.com

Basically I just changed these settings :

• Video Codec (FPS) to : H.264(x264)
• Video Framerate (FPS) to : 30
• Audio Codec to : AAC (Core Audio)
• Audio Mixdown to : Stereo
• Audio Sample rate to : 44.1
• Audio Bitrate to : 256

Answer 2

We ended up having this problem as well and couldn't for the life of us come up with a file that would work.

As it turns out, the video was fine all along, but iTunes Connect has a very short upload time window. Uploading a 39MB file on an ADSL connection with 800kbit/s upload is apparently not good enough. (it didn't even work with a shorter, lower-quality 13MB file) It all worked fine first try via the iPhone's 3G personal hotspot with a 4Mbit/s upload speed.

Of course, that's not what the error message says. Sigh.

convert your videos online using this site http://video.online-convert.com/convert-to-mp4

and set the following

vid bitrate : 10240

frame rate: 30

audio quality: 256

Answer 4

If you're using ffmpeg:

ffmpeg -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=44100 -i input.mov -vf scale=886:1920 -map 0:0 -map 1:0 -shortest -strict experimental -r 30 -y appstore.mp4

I've used in on videos recorded using QuickTime

Answer 5

Tried everything explained in other answers regarding Video settings. Still did not work for me.

I just restarted Safari and it worked. 😔

Answer 6

For me the problem was that the clip was 14.8 sec long, which is below the required 15 sec minimum, but somehow the „uploaded clip is too short” error didn't fire either. Making the video 1 sec longer solved it.

Answer 7

Quic tips. Try with safari. I have resolved similar.

• Recorded video from simulator.
• Edit in iMovie App Preview feature
• Upload via Chrome Error:one or more of your app previews contain unsupported or corrupted audio
• Then try with safari and its working properly

这是因为互联网连接不佳，您必须等待几分钟，直到“保存”按钮突出显示，所以让它进行处理，当“保存”按钮突出显示时保存它，即上传成功。
