The only place I have used is this:

https://aeroquartet.com/movierepair/download

They saved two files for me and have been completely reliable. They send you a small application, as I recall, which samples your file. You send it back to them. They then send you an application which is set up to fix your file.

This is from their site:

What can Aero Quartet offer you?

Very reasonable prices and they are fast. It worked for me – twice.

I used something called “Free AVCHD to .MOV”. You can Google it. Amazingly, it worked. I transcoded to ProRes422 LT. At first I saw nasty interlacing and messed around with various de-interlacers. But, mysteriously, the problem went away. I just hope it doesn’t return.

By the way, after transcoding it to ProRes422 LT, per above in Free ACV etc, I imported the files (which were continuous) into FCP 7.03 and then exported them as one QT ProRes422 LT file. This was to make a Multiclip.

It may be that the weird interlaced artifacts magically disappeared during the export. I can’t remember.

Anyway, Free AVCHD to .MOV is free. And it’s good quality too.

Let me know how you get on. Curious to know your results.

Hail, O Wise One …

Thanks so much for responding. OK. I will do as you command. I do use SuperDuper to back up my zillions of TBs of movie files to a massive set of eSATA drives which reside in a forest of red hot toasters, so will take your advice and do the System drive the same way and eschew the Nazi Time Machine in future.

And thanks for the advice about Yosemite … I’m moving over to (gulp) Premiere Pro and have received nothing but bad advice from the Adobe people, so it’s a relief to get reliable advice for once. Of course, this presupposes that you have not taken leave of your senses.

Excitingly, I am upgrading from my Mac 2,1 to a 4,1 from OWC. The choice to remain in the Mac dark ages was made simply because I enjoy opening up the side of the Mac towers and fooling around with the wiring when I have nothing special to do. Plus, it’s easy on the wallet. So it’s a huge temporal leap for me of 2 full years in Mac construction – from 2007 to 2009. Phew.

Trust all is well with you and that you are, largely, behaving sensibly.

Pip pip.

Best, Harry.

Tim,

Thank you so much for having the patience to reply and explain.

I greatly appreciate it.

Best, Harry.

Thank you very much for the response. Although I could shift the tracks around to get them into sync, Premiere Pro is supposed to be able to do this for me and I am almost certain that it is me who has made a mistake somewhere in the process.

Thanks anyway,

Harry.

Thank you for the reply.

As I said in my original post, there are 4 files involved. So I am attempting to sync up 4 audio/video files. There are no audio gaps. There are no gaps of any kind. They are contiguous files which synched up just fine in Pluraleyes.

Many thanks for your time,

Harry.

[Harry Bromley-davenport]

Thank you very much for your response and suggestion.

I can see that the 4 video/audio files have staggered start points. This is good and what I would expect.

Also, the start points of each one of the video/audio tracks appear to be in sync with themselves in that video and audio appear at the same moment on the timeline.

By a process of soloing and muting the 4 individual video and audio tracks, I find that all the audio is synched up ok. However, none of the 4 video tracks is in sync with this perfectly synched audio.

However, Video tracks 1 and 2 are in sync with each other – but those 2 video tracks are not in sync with the audio – nor are they in sync with video tracks 3 & 4. Video 3 & 4 are also out of sync with each other

Clearly I am making a major mistake.

Perhaps you have an idea? Or another test for me to do?

Thank you again for your time. I truly appreciate your response and apologize for my stupidity. By the way, I’m an experienced editor who has been with FCP from around the year 2000. So I’m attempting to jump ship.

Harry.

I’m trying to sync by audio waveform. There is definitely audio on the tracks and these 4 files sync up ok in Pluraleyes.

I go to the “Create Multi-Camera Source Sequence window and check the AUDIO button. For “Track Channel” I have tried both “Mix Down” and “1”.

I have tried with and without “Move Source clips to processed clips bin” checked.

Below, where there is a box marked “Audio”, I have not experimented but have left the defaults: “Sequence settings – camera 1” and “Audio Channels Preset – Automatic”

Any ideas?

Many thanks for the response.

Harry.
