I have Quicktime 7.7.9 installed. As I said, what I can't understand is why files like the one above load into MEP 17 Plus with no problem on this machine, but not the latest MEP version.

Hi

. . . . what I can't understand is why files like the one above load into MEP 17 Plus . . . .

Does the above file load in to MEP 17?

I suspect it will not as from the MediaInfo analysis

Format                                   : ProRes
Format version                           : Version 0
Format profile                           : 422 HQ

Prores 422HQ is not supported by Movie Edit Pro, if this is a codec format you will be using regularly you may want to consider moving up to Video Pro X which does, on my testing, support ProRes 422HQ video - try the trial version first.

Check the MOV files that MEP 17 does import - I suspect they will be either AVC, h.264 or JPEG encoded video.

The file details I sent you are for a video that imports into MEP17 no problem. I just checked it again. There is an error message reading: "Unknown error occurred during audio extraction", but that is simply because the video is of a silent film - so no soundtrack at all. In fact, I have many video files of this type and I have been using them with MEP17 without difficulty for about four years.

Just some additional information. The version I of MEP17 I have is the PlusHD one. Also the MOV file plays perfectly well on Quicktime.

Hi.

That seems a very odd frame rate being reported. Is that correct?

Can I ask what device the file comes from? You say the older version of MEP is handling it but it seems like a new format of an existing file type. Most unusual an puzzling. Really high bit rate as well for a 1080p file. Quite impressive.

[Edit] Can I also ask the recording medium? What type of card and write speed is needed please?

Ray.

All my ProRes files are of old cine film of various gauges and they were transferred by a commercial company. The frame rate chosen by the company was the lowest usual rate for silent standard 8 mm gauge film, although some of the films had soundtracks and therefore were filmed at a higher frame rate. The details I sent you were for a silent film so 16 fps was quite normal. I don't know why the bit rate is the way it is. I'm sorry, but I don't understand the rest of your questions. What exactly do you mean by recording medium? Is that the original film? If it is then I have answered the question above. As regards the card and write speed, do you mean the graphics card? If so, it is an AMD Radeon RX550, I hope that makes sense. I couldn't see any information about write speed.

I really think this must be a bug in the new program, because once I have created a project in MEP17 with the ProRes file I can then load it into MEP 2020 with no problems and it reads the file flawlessly and allows me to edit and apply effects as usual. I can even delete the ProRes file in the project and then load it in again without any trouble. If I try to load any other ProRes file into it, however, I again get the error message.

Hi.

That may be useful information to others, hence my questions.

First, we didn't know the origins of the files so the info you gave on your files have nothing to do with the original recording medium and were the result of having them professionally transferred from film into a digital format.

That is information we didn't have before and may help someone else here understand the problem better.

The rest of my questions were centred around thinking they files had come from a digital camera of some sort. So no longer relevant as you have now clarified the situation of the original source of the files.

The high bit rate I referred to was probably the result of the transfer method trying to extract as much detail from the film images as possible.

It would seem from what you have further described that there may be a bug or problem that you have found and would be best dealt with by the Magix technical department than here.

Equally there could be a member here that has had a similar problem and solution that has not looked at the forum post yet but my bet would be to get in touch with Magix through your Magix email account and raise a ticket for a reply.
