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 interlacing on the old footage is upsetting FCP and iMovie.

Strange that other playback apps and NLEs are immune.

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 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 need to be imported. Another solution is to delete the FCPX cache and restart FCPX to fix transient red clips caused by a “stale cache” problem. This can happen due to a drive going off line or multiple external drives mounting in a different order after restart.

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 were spread out so I was able to verify that Shift-Z did work.

Thanks for both your responses.

A short time ago I managed to contact a shop specialising in these bulbs and was assured that the advice was purely for preventing mechanical damage when screwing in the bulb.

They said there was no problem with fingers touching and handling the glass other than making it mucky . . . but as we are not likely to be draining the oil in our car engines at the same time, there should be nothing to worry about!

Thanks for your valued input Andy and Jeff.

The point about editing initially in 50p is interesting.

I think the reason I plumped for 25p is that I’m using a 2008 Core2Duo iMac with 4GB RAM so rightly or wrongly I assumed that to edit in 25p would be easier for the computer.

My delivery comes in 3 forms . . . 25p for DVD/BD and the internet for other people, with 50p for my personal viewing using my BD player as an .mp4/h.264 media player.

Use this free app to automatically trash preferences.

https://www.digitalrebellion.com/prefman/

Shut down FCP 7, open PreferenceManager and in the window that appears:-

1. Ensure that only FCP 7 is selected.

2. Click Trash

The job is done instantly and you can re-open FCP 7.

There is absolutely no danger in trashing preferences and you can do it as often as you like.

The preferences are kept separately from FCP and if there aren’t any when FCP opens it automatically creates new ones . . . instantly.

Many weird things happen as a result of corrupt preferences which can create a vast range of different symptoms, so whenever FCP stops working properly in any way, trashing the preferences should be the first thing you do.

Although the problem arises with FCP X and QT X there is an obvious difference in the video files as you can see in my first screenshot.

The “good” ones have a poster frame and the “bad” ones don’t.

In an effort to track down the cause I captured some analogue PAL using my DataVideo 100 and FCP 7 but the results were perfect.

If I get time tomorrow I will try the same using my Canon HV20 as a converter to see whether that is the culprit or not.

[Ian Brown]

My DataVideo converter and Canon HV20 are both set to capture DV PAL.

They were used connected to my iMac running FCP 7 at the time.

The only variation that I am aware of is that some of the 20 odd tapes were captured with the DataVideo and some with the Canon.

It would be enticing to think that the 5 dodgy ones were captured with just one device and the rest with the other.

I haven’t had the opportunity to test both devices to see if this is the case.

However, the dodgy files are not really dodgy as they work perfectly with FCP 7 and QT 7 . . . . . its just that they throw a wobbly when used with their successors.

They must also contain all the video and audio info otherwise Save As would not be able to make perfect working copies.
