H264 to Proress422(HQ) Final Cut Pro 7 without Log/Transfer
on Nov 8, 2012 at 8:36:53 am

Will try to make it short.

Shot a feature film on Canon 5D. Converted to Prores Proxy and edited. Finishing film and tried to use Log/Transfer to upres to Prores422 (HQ). No luck. Searched forums and for many technical reasons I believe I will not get the Log/Transfer function to work. Horrible but...I seemed to have found a solution but it is something I have not seen on threads and I feel I maybe missing something.

If I bring the prores FCP project file onto my Macbook pro and open it without the prores proxy drive attached to the Macbook FCP of course asks to reconnect the media. If I connect the h264 drive (camera original files) and point FCP to reconnect the media in the sequence to the h264 files it reconnects the files almost perfectly in the Sequence. I then simply changed the sequence setting from Prores Proxy to H264 in FCP and it seems then I have a h264 Sequence of my picture lock sequence.

Now if I export a 422(HQ) movie from this H264 sequence timeline it would seem then I have solved the problem and have a prores 422(HQ) movie. It seems simple, to simple and I have not heard of this process before. Since the project is heading for festivals, I of course want to try to keep as much of the original quality as possible.

Am I missing something?

Also as another option I may have found...I was able to export an XML after creating the H264 Sequence to Adobe Premire and also open it up using the H264 files. Is this a better option? I hear a lot that it is since Adobe is 32bit? This is pushing limits of my knowledge.

I'd ideally just like to stay in Final Cut as I am familiar with the program but if there is a really big difference, which I'm guessing there not, I'd try to maybe take the leap into Premiere.

Any feedback would be greatly appreciated!

Thanks,
Chanho

[Chanho Kim] "Shot a feature film on Canon 5D. Converted to Prores Proxy and edited"
the problem is how do you converted the H264 to Prores Proxy in the first time.
If I'm not wrong the way to go is through a FC Canon plugin that lets you L&T and reconnect to the original media.
The problem with that media is that has no TC, so reconnecting without that plugin may work or may not work.

If you are able to reconnect the original h264, why don't you change the sequence codec to Prores HQ?
The H264 > Prores conversion will be done on rendering the time-line.

Hi Rafael,

Thanks for the info. Prores proxy was actually created through FCP Log/Transfer and Canon plugin. Problem is names of drives and folder I believe have changed as several different parties were involved in the post. Possible drive or folder changes I think maybe the fatal mistake. Did a bit of research and tinkering and was only able to get a few files reconnected but the majority would not reconnect. Problem with not recognizing volumes in Log/Transfer, which is covered a bit in the forum and seems like a common problem when file names are switched. Seems like Log/Transfer function a bit touchie from the post I read anyway.

Changing sequence settings seems like it would work also but similar export times as exporting.

It sounds like workflow I'm trying will work. The real pain without working with the re-conformed sequence from Log/Transfer is exporting individual clips for After Effects for some effects and slow motion. Adds an extra step and FCP really does hate H264!

Thanks,
Chanho

OK a few things to cover here, because judging from the post I'm not sure how much you understand the whole H264/ Prores thing.

For a start, unless specifically asked, don't bother with Prores HQ. Standard Prores is just as good for H264- you cant add quality where there isn't any, and HQ will just give you bigger file sizes with no extra gain- remember, you can't 'upscale' into prores 422. Something which shoot natively in Prores422 is a very different ball game.

Secondly, you may not quite get why we do this- its not that Final Cut can't handle H264 files at all, its that theyre terrible to edit with, for various reasons. The whole point of importing as prores BEFORE you start an edit is because if anything's going to corrupt a sequence, it will be H264, and that plus rendering and colour space etc, its worth bringing them in as prores. By Changing the sequence to prores and exporting that, again you wont gain any quality- H264 is a good format to provide the final product in anyway (indeed bluray is H264 if I remember rightly)-so there's no point in doing that. Again, this isnt about losing or gaining quality, its about making it a faster and smoother editing experience. For example, a minute of footage that needs rendered when all the footage is prores could render in say 10 seconds, whilst if the footage and sequence is all H264, it could take a minute.

As for the Premier thing, no its not a better option, although a few may tell you different. Premier is a 64 bit application, and it also renders in the background, but if you are not familiar with it then leave it alone IMO- its not doing anything FCP cant do other than render in the background, which sounds great but I know in my case my knowledge of FCP is enough to make up for the time it takes to transcode everything to prores and edit.

If you are having trouble with the log and transfer tool, use mpeg streamclip to transcode everything into prores then just reconnect to that.

Hi Thomas,

Thanks for the response.

Log/Transfer of all the footage was done a 4 months ago and we are actually getting ready to upres the picture lock. Log/Tranfer is not working so the the steps I explained was a work around that I figured out and asked for feedback.

Thanks,
Chanho

Hiya,

Thats cool, the workflow you suggested would work, but my question is why do you need to supply a prores HQ film? Have you been asked for that? Because you can't 'upres' really as the footage is the footage. It seems a bit of a redundant thing to do is all :)
