I don’t have any problem with normal AVCHD files. They have always worked perfectly on my Intel iMacs in the past and the M2 and M4 minis I use now.

FCP 12 handles them perfectly so long as I don’t rewrap them.

That’s correct. That is what it does with me and the problem is caused because FCP doesn’t like rewrapped files or at least those rewrapped by Shutter Encoder.

Anyway it doesn’t matter to me as I only shoot progressive AVCHD nowadays which does not have that problem.

I just raised the matter originally out of curiosity to see whether anyone else had…

I have discovered the problem . . . I uploaded the dodgy .mp4 instead of the original .mts

Here is a new link . . . .

Ignore my earlier reply.

I have just downloaded the file and it is jerking as badly as ever.

There is something wrong with the file I uploaded. Maybe I uploaded the bad one or maybe the cloud storage has corrupted it?

I can’t explain why you are having problems with the original file.

Joema in the link I provided has found the same results as me . . . normal AVCHD files play perfectly in FCP but those rewrapped in Shutter Encoder don’t.

In the ASC FCP forum joema has tested some old interlaced AVCHD files in Shutter Encoder and confirmed that they don’t work in FCP.

I have just CONVERTED the .mts file to H.265 in Shutter Encoder and it plays perfectly in FCP . . . BUT that is not the point.

I always knew it would work that way as a progressive file but it should also work as a rewrapped interlaced file. FCP is crazy but I have always known that as well. 🧐

I wonder if earlier versions of FCP X would be able to…

Thanks! Everything back to normal now.

Just noticed the file plays awfully online but seems OK once downloaded.

It works perfectly in DaVinci, QT Player, VLC and Quick Look.

Anyway, as I said I am not really bothered as I don’t need to do it . . . I just hate being beaten!

I have uploaded one AVCHD file from 2012 that has been converted to .mp4 in Shutter Encoder.

Maybe you or someone else could download it and see what…

I just tried to send a reply but it was blocked and considered as Spam!

I transcoded to ProRes 422 but the jitters were the same.

It does not matter as it was just an experiment to see if I could find a better way.

For the last few years I have been shooting 1080p50 on my Panasonic SD800 which seems immune to the problem so it looks as though the…

I managed to get a reply to Mads by creating a new discussion but I could only send the first couple of sentences. What is going on?

I just tried to send a reply but it was blocked and considered as Spam!

I transcoded to ProRes 422 but the jitters were the same.

I think that might work Mads but the whole point of my experiment was to see if I could keep the files small and in a more compatible format.

It’s not a problem as such because I am quite content with the way I have been storing them for the past few years but I thought I might try rewrapping them. It was just an experiment which has unfortunately failed.

Thanks Devrim but I tried all those before posting . . . many times.

I keep all the memory cards from my Panasonic SD800 camcorder together with backup copies of them on SSDs. Yesterday I decided to try out Shutter Encoder’s ability to rewrap the AVCHD/.mts files as mp4s. The originals were shot as 1080/50i (interlaced).

Shutter Encoder did a fine job and the new .mp4 files played flawlessly in QT Player, VLC and…

I got this from a web search.

If you encounter the error message “This item cannot be shared while it is still referencing media on the camera” while using Apple Final Cut Pro X, there are a few possible solutions. One solution is to go to File / Import / Re-Import from Camera Archive, where FCPX automatically finds and re-imports the files that…

Thanks for the Shift-Z information. I knew about using it in the timeline but not in the browser.

A strange thing just happened. I launched FCP and to my surprise all the long clips were small single icons. I couldn’t believe it so I quit and launched several times more and each time the single icons were there.

Eventually I launched again and they…

I prefer to have my clips display in the browser as a single icon regardless of their length and have set them accordingly.

However, each time I launch FCP X they have reverted to the default setting and are extremely stretched out.

This has been going on for years and currently I have a 2012 Mac mini (Catalina) and a 2017 27″ iMac (Monterey) both…
