I have been making some videos instruction and promotion videos for my app using the mobile app Kinemaster. (recommended at EMDC)
When I try to import a video made with the Verse on Image feature it says ‘unsupported video codec’. Does anyone know why this is? The same happens when I try to open it with another app called Video Compressor, it even lists supported formats (mp4, etc.) which clearly isn’t the problem as the saved videos are mp4. I have tried renaming the files so there are only standard Latin characters but that doesn’t help.
The videos open fine from the the gallery or in WhatsApp or anywhere else.
Is there anything that can be done to the way the files are exported to fix this? If the error code was more specific about the problem that would be helpful.
If there is any more information from my end that would be helpful let me know.
Others can speak to this better, but in my limited understanding MP4s are containers that can hold audio, video, images and subtitles, and can support several different video codecs (like h.264). I’m not sure which codec SAB outputs to, but it sounds like could possibly be one your programs don’t support. This does seem strange, though. Someone else can confirm what SAB uses, but you could search under MP4 codecs for your Kinemaster and see what you find.
Using MediaInfo on Win 10 machine I got the info below about a video I created in a SAB app.
The KineMaster specs are pretty sparse but It does give the following formats for export:
- MP4 (H.264 Baseline/Main/High Profile + AAC LC / PCM)
- 3GP (H.264 Baseline/Main/High Profile + AAC LC / PCM)
- MOV (H.264 Baseline/Main/High Profile + AAC LC / PCM)
And the this format for export:
- MP4 (H.264 Baseline + AAC LC)
So looking at the exported file, it is in a mp4 container
The audio is the same as the KineMaster exported file.
But the Format Profile is: Simple@L1 which compares to the KineMaaster export that has: Baseline@L3.1
So Is it really the codec or another part I’m not sure.
A quick google said that PowerDirector can convert SAB video to one acceptable by KineMaster.
If we change the settings to generate for KineMaster will it break for other users?
