Thanks, however, the link you provided does not apply to the same issue or error message. It discussed a different problem regarding audio. As described in detail, this is not the issue I am having.

Also, it is a bit annoying for the error message to indicate: Unknown Error. So if the software is not able to determine the error, how must the user then resolve it?

Here is the media info:

@Eon-deKoker Try another graphics hardware in the program settings (for example switch from GPU to iGPU) or re-encode the video with a free software like XMedia Recode to a format that can be imported.

Sorry, I pasted the wrong link, it should be https://www.magix.info/us/forum/mxmpeg2-error-0110-no-media-decoder-found--1330504/#ca1897264 (I know that the topic refers to MEP 2021)

That said, I think the problem is indeed the VP09 codec; I'm sure others that have in depth knowledge of codecs etc. will correct me if I'm wrong and point you in the right direction.

Edit - I have the same error message when trying to load a VP9 file into MS 2024

@Eon-deKoker

Hi

As @me_again commented the issue is with the VP09 codec, it is not supported by MMS 2023, you need to convert the video to a supported format, eg h.264 video and AAC audio using a video converter such as Handbrake or Avidemux.

Edit:

For future recordings on the iPhone, use h.264/AVC format recording, if storage space is limited, or the iPhone does not support h.264/AVC, use h.265/HEVC if available.

VP09 is a not a good format for editing due to its high compression.

All I want to do is edit an iPhone video. If software cannot do something this basic for all the iPhone users then something is wrong. As SP proposed, I recoded the file with XMedia Recode to MP4 and this works fine. But why it this not supported by default?

FYI, the iPhone video settings was Most Compatible and shows H.264. The only other option was High Efficiency HEIF/HEVC.

Hi and welcome to the user to user forums.

Apple developed the mov file wrapper for Apple and as with all their products would prefer to make anything they provide only fully compatible with other Apple products.

That is deliberate as they want an enclosed ecosystem and people to not just buy their phones but computers, iPads etc. File conversion is the only option if working on a Windows computer. Even Adobe Premier has to be run on an Apple machine to work with the files in their native form.

In the past Apple made their QuickTime player available for a brief while to Windows so that the mov file format could be edited but that has long past. Apple keeps changing the mov wrapper and codecs contained within them. They say it is done to make the ecosystem secure. It's just the way Apple works.

Hi

. . . . why it this not supported by default . . . .

You would have to ask Magix that question.

In terms of usage, despite being available for 10 years the codec, is not that popular, other than being used by some streaming services eg Youtube.

VP09 (VP9) is being replaced by the AV1 codec which is becoming more popular, and is supported by Movie Studio 2024.

. . . . iPhone video settings was Most Compatible and shows H.264. . . . .

Agreed, that is one of the two codecs supported by the iPhone XS the other being HEVC (h.265). VP09 is not an iPhone XS, or any other iPhone I know of, codec.

However, that is not what the MediaInfo data shows, additionally in the MediaInfo analysis this line:

Title: ISO Media file produced by Google Inc.

Suggest the video has been converted and is not the original iPhone file, which leads to the question of where has this file been, eg uploaded to, for it to be converted?
