I'm not convinced you're actually experiencing the AVCHD bug in CC. Let's take a look at that and see if we can get it working for you.
Let's start with your hardware specs, and go from there.
Other compressed formats, such as MOV files, don't give me any playback issues. But I'm open to whatever solutions you may have in mind.
Here are my hardware specs:
Intel Core2 Quad 9550 (Overclocked to 3.2Ghz)
Nvidia GTX 560 with 2GB video RAM (have done "the hack" to allow CUDA support)
16GB DDR3 System RAM
Hard Drives (all 7200RPM WD Caviar Black)
- 500 GB System/Programs
- 500 GB Media Cache
- 2 x 1000GB (Raid 0) Video Projects
- 1000GB Storage
Gigabyte ga-ep45-ud3p motherboard
Intel Core2 Quad 9550 (Overclocked to 3.2Ghz)
Well, there's your problem. You won't get buttery smooth performance with that relic. It'll be even worse with multicam work.
You really do want an i7 3770K or an i7 3930K for this stuff.
I really don't think my CPU is the problem. I do multicam work all the time on shorter MTS clips. Up to four cameras with hardly ever any choppy playback. Typically anything less than 20 minutes or so is fine. It's only the longer clips that give me problems. And the performance didn't improve with CC.
On the other hand, I can take just-as-compressed footage in H.264(mov) and play longer multicam sequences just fine. I only get the playback issues with AVCHD-compressed footage.
Regardless of whether this is actually the AVCHD bug or just some bottleneck in my system (which I firmly believe it is not), I'm still left with the task of re-linking footage with a different file extension. Did Adobe only expect us to relink to footage with the same extension, or am I missing something here?
I feel like we got off track here. Is there really no way to batch re-link to media with a different extension?
Maybe someone from Adobe can chime in here?
I haven't tested CC yet, but... What happens if you uncheck 'File Extension' while keeping 'Relink others automatically' checked in the 'Link Media' dialog?
If I do this, it only links the first file with the version I'm trying to link to. The rest of the files get linked back to the last location they were linked to (in this case, the proxy versions).

The new relinking feature is designed to find the original files; it is not really intended to support a proxy workflow. That said, if the program cannot find the original files, it will look for others that match certain properties and ask if the ones you find are what you want to link to.
So for your workflow, try "hiding" the original clips from Premiere by either keeping them on an external drive that you turn off or by moving the folder. If you go the latter route, I believe you will get better results by moving the original folder up rather than down because the code is designed to drill down deeper from the last known location.

I tried your suggestion of moving the original folder up a level to throw off the programmed behavior, and it was able to batch-relink to the alternate files I was pointing it to. So this definitely does provide a workaround for relinking proxy files.
I can also see how the relink feature could be made to work with a proxy workflow by leaving the file extension off of the referenced file name. So, for instance, instead of referencing "Clip001.avi", Premiere would search for "Clip001" with whatever extension it might have.
It seems redundant to have a checkbox for "File Extension" under the search parameters when the referenced file name already includes the extension, and there is no existing option to not include it.
I'm sure there are plenty of other editors out there who would like to use proxy workflows on Premiere, and would welcome this change.
I have the same problem. AVCHD files corrupted by premiere and need to convert in other extensions, and relink proxy files. (Problems that didn't exist in Cs5).
Have you fixed the problem moving the original folder? It doesn't work for me.
I moved the original folder up a level and then relinked to another folder containing my proxy media. You'll also want to make sure the "File Extension" box is unchecked and your file names are exactly the same.
AVCHD files corrupted by premiere
What makes you think that?
AVCHD files shooted with Panasonic Lumix GH2 (hacked) worked well since Premiere Cs5. From Cs6 to CC editing creates orrible artifacts above the video, and everyone shooting with Gh2 is obliged in converting files in other formats. It's a big issue, a lot of forum talks about it and a lot of videomakers are asking to Adobe to solve this problem.
ps. excuse me for my poor english
I use the GH2 myself and have had no problems with my footage using either CS6 or CC7.
Are you talking about the 'rain' problem?
I have done some work with proxys in premiere cs5 when avchd would not play. Trick is to create the proxies with mpeg extension rather than avi. (I used media encoder). Then rename the extension of avchd clips to mpg. Premiere doesn'y mind avchd files ending with .mpg
Yes the rain effect. I have it in every single project. I'm using Flowmotion hack. Anyway it's a random effect, one day you don't have it and the next one yes, it's very boring.
Did you rename the extensions in batch? (if yes what program did you use?) Or manually?
I'm using Flowmotion hack.
Try Nick's Moon Trial 7. It beats Flowmotion 2 in quality, and being an I-frame hack, doesn't seem to suffer from the 'rain'.
(By the way, PP isn't really 'corrupting' those clips, which would mean they were somehow changed by PP and are no longer playable anywhere.)
batching changing filename extensions can be done in adobe bridge (select all files/ right click/batch rename/settings there) but I also use a freeware utility called rename. It's excellent.There are others which are equally good.
Is it 100% stable as Flowmotion? I need it even for weddings, shootting almost 40 Gb per day.
Give it a test with your cards. I'll be using it for my first wedding on Saturday.
I have edited on GH2 files and on Canon C100 files. It's the same junk. AVCHD is a pain. I have CC and I put my files in Media Encoder. I transcode the following way.
I batch convert everything to "FORMAT: QUICKTIME"
PRESET: CUSTOM (so choose 720p and then change the VIDEO CODEC: I change to DNxHD (I work on a PC with Windows 7) Before someone chimes in with "get a new computer or buy a MAC" we use both, so that argument doesn't fly. So when I use a PC where ProRes is not available I do this.
OK back to the next step: Under "CODEC SETTINGS" I choose
COLOR SPACE: 709 "NONE"
1080p/original frame rate DNxHD 36 8 bit
Then it batch converts it all and I save it to a separate hard drive in my tower.
I use a hard drive dedicated to just putting my proxy footage in there for editing. When any computer whether it be your Mac Pro or PC tower tries to read the files all from the save drive it'll put more stress in one place making your editing a lagging nightmare. Spread it out and keep organized.
I then import my footage into Bins and name the Bin "blah blah proxy footage" Then I edit and the footage is buttery smooth. I have 16gb of ram and it's more than enough for this type of thing. Ok Here's where my issue comes in.
After I've added my cross dissolves and my color corrections, and I'm done rendering my footage, I've yet to figure out how to automatically relink everything to the original .mts files such that it'll be in the same place for each clip. Meaning if I click "replace with " and select any of the three options, it throws in all the .mts clips but assumes that it the clips all start from their recorded starting point rather than my in and out points. So what I've had to do thus far with CC is go through each clip individually and look with my eye for the place where it lines up. It's a lot of guess work and I use timecode and it takes FOREVER! I didn't have this problem in previous versions. I've attempted to delete the .mov footage to make everything go offline and reconnect to my .mts files and it still puts the wrong in and out points on each clip. Needing to fix this!
I'm pretty sure you can do in now in Premiere CC.
I just re-linked footage that was proxyed with a small mp4 file with an mov file.
Just unclick the "match extension". It re-linked the footage. I was even able to flip back and fourth. If all of your footage is proxyed in one folder and source from another, it should work to relink them all.
After you have a no folder with the footage you want replaced, trash the folder with your original footage. After everything is relinked correctly, take the original footage out of the trash and put it back to where it belongs. Voila!
Hi I hope this thread is still answered.
Your (Adobe) explanation and workflow is not working here!
I had a big project with .mts files. Then I transcoded them into .mxf and deleted the mts. So the folder and file structure is still the same, only the extensions changed.
I now can relink every file, file by file. I can not figure out how to do them all at once, folder by folder.
In the relink dialog box I uncheck "file extension" and i check "relink others automaticaly", but it only changes the first, selected, file.

Thanks a lot
Okay, I have just found a work around that completely solved this issue for me, thank goodness!
I was trying to replace my MOV proxies with the original R3D and MXF files, but I couldn't do more than one file at a time. When I had "relink others automatically" selected, it would only connect the first file, and then the rest would default to my proxies EVEN IF I renamed the proxy folder so Premiere shouldn't have known where they were.
The trick is to move the proxy folder upwards in the file system. This stops premiere from finding the old proxies.
BUT, I was still having issues with my RED footage because it splits up some of the clips into multiple R3D files. So I unchecked "extension" and "name" in the locate window and checked "media start" instead. It takes a little while to connect, but it sure beats doing it manually one by one! I found too that if you change the file structure of the original footage to match the proxies, this also speeds things up.
Excellent tutorial for figuring this stuff out. Watch the whole series including the video descriptions and comments for other troubleshooting. Good luck!
I have the same requirement- to use proxies to offline and then relink to masters with a different file extension (...I'm actually surprised this isn't easy.) I have followed the steps outlined by Monkeyeatsmonkey and Mark but I still can't get PP to see the files even with "File Extension" unchecked.
I have shot ProRes HQ 422 and am finding this isn't working in my system (Windows 10.) So I have made DNxHD files that I want to use as proxies. Of course the ProRes have the .MOV extension and the DNxHD are .mxf files.
I can't figure out what I am doing wrong- can anyone help me figure this out? Maybe walk me through it step by step.
Okay, I have solved my problem relinking proxy media to original media with different extension name.
here are my steps
1. Make media off-line
2. Select footage and link media
3. On "match file properties" only select "CLIP ID"
4. Now locate your folder with the original media and everything should relink automatically.
I hope this works for every body, if you have any trouble try to move the proxy folder up a level and repeat steps 1 - 3
