Thanks. How did I miss those avchd 1280 x 720p preset?
Anyhow, using the correct preset doesn't solve the problem. After putting a certain number of avchd files from the project window onto the sequence, the thumbnails of the last few clips turn into solid green, and the app is on the verge of freezing (I couldn't even exit). All clips play fine while still in the project window before dropping onto the sequence.
After killing premiere to exit, the "importprocessserver" had to be killed separately.
Try deleting your media cache. Then close and reopen your project and let the conforming and indexing of your files finish before trying to edit.
have you tried putting half on one timeline and the other on a second timeline then nesting those 2 timelines in a third ?
try that and see if it works.
not really fixing the problem but it might work.
My gut feeling is that the media cache still contains material from the previous and incorrect HDV project. I think/hope that cleaning this up will result in only AVCHD cached files and remove the problem. Since the clips all play OK in the project window, it does not look like there is anything wrong with the material as such.That could be easily checked by creating a new timeline and only moving the latest clips, that cause green screens, into the new timeline or playing these clips in the source monitor.
The question should also be asked; are you waiting for the files to be fully indexed/conformed before you work?
In post #3 I told the OP to wait until indexing and conforming is finished before starting to edit. I just hope he listens.
Ah, I missed that.
I ran memtest86 and it found 2 bad addresses after running for 15 minutes
I guess there's no point in continuing this thread until I fix the memory. Sorry I should have tried this sooner.
Thanks for all the help.
Too very often, users miss that little progress bar at the lower-right, and begin happily editing. Often, they get hangs, and crashes, or the "Media Pending" message, and become highly concerned. Would be good, if there was some message, that suggested "patience," and maybe even suggust that this would be a good time for a cup of coffee, or tea.
Fixing the memory problem unfortunately does not fix the premiere problem. I also deleted the swap file (actually set the swap file to another drive).
I ran another premiere test. First I deleted all files from the preview folder.
This time, I found that after dropping the 70+ avchd files into the project, the system is already unstable. Some files are already playing as a solid green screen from the project folder before I put anything on the timeline.
I rebooted and started a new test. This time I import 10 files at a time. After each import, I verified each of the 10 files play fine in the project window. After importing 50 files, I found that the first 20 files no longer play correctly. Sometime they stutters, sometimes they play backward, sometimes they turn into a green screen.
Any more ideas?
You still haven't indicated whether or not you're letting the indexing/conforming process finish before you start editing.
I drop 10 files at a time into the project. I wait for indexing to finish -- actually, it takes less than 1 second to do the indexing so it's very difficult to not wait for them to finish.
Then I drop another 10 files, and so on.
This time, after dropping files 31 to 40, file 32 to file 40 all have problematic playback (stutters, turns green momentarily, etc). The earlier files still play fine.
Then I try to exit premiere, and answered no to save project. It hangs after that dialog without completely exiting. I have to kill it.
In this project, I purposely did NOT create a sequence. The problem occurs just by dropping files into the project.
just as an experment try converting the AVCHD file to DV AVI II ( or use one you already have )
once you have the AVI tri copying that file and re-naming it to different names and then importing it.
maybe it has nothing to do with AVCHD and it is a bug with importing files ?
I know this doesnt fix the problem. ( just an experment )
Sucks when things dont go the way we want them to go.
This is a bit of a long shot, but worth a test: do you have the "Write XMP ID to files on import" option checked? It's found in Edit > Preferences > Media. If it's checked, uncheck it and try the import process again. I've found that, while this option generally causes no problems, with some formats (particularly those that are temporally-compressed or otherwise "non-standard") it can wreak havoc. Premiere will attempt to write the IDs to the imported files, but sometimes this is flaky and what actually ends up happening is that Premiere corrupts/breaks the files. If nothing else, it can get caught in a feedback loop as it will try to write the ID, can't, and then tries again, either during the same session or on a revisit to the project. Incidentally, this is a good reason to NOT work on your original, irreplaceable footage files.
Again, no guarantees, but it's worth a test.
I used adobe media encoder to convert all 70+ avchd into dv avi (wide screen 720 x 480).
Then I created a new project and imported those 70+ avi files. No problem. I further put those clips on a timeline -- no problem either.
The only problem is this conversion lowered the quality of the video to worse than average DV clip. I can see large pixels (or artifacts). If I can find a better file format to convert these avchd files into, that may be a good workaround to the problem.
Still, I'd like to know why importing 40 avchd files would destablize premiere. I was thinking of buying a nicer avchd camcorder ($1000) but would have to put off that idea until the editing issue is resolved.
good to know that you can get all the files in after converting.
bad that the quality dropped.
did you ever try nesting so you only had half on each timeline ?
you said that you can get 40 on before it crashes.
make 2 timelines then nest them if you can.
I was wrong saying the files are avchd files. They have .mp4 extension and according to the camcorder manufacturer they are 720p HD mpeg-4 avc/h.264 format.
I found that as long as I don't preview or generate a thumbnail of the clips, I can import all 76 clips no problem. This can be achieved by turning off the preview area and turning off thumbnails. I can save this project and load it back no problem.
But if I turn on preview area and then click on (select) different clips in the project window, after 22 thumbnails or previews appear, the next thumbnails would be solid green, and then premiere becomes unstable. Also, the 22nd thumbnail takes a fraction of a second longer to preview than the previous 21.
BTW, not just mp4 files, wmv files also has the same symtom.
If you want to reproduce this, try:
(1) in premiere, create a 2 second or longer video clip of 1280 x 720, 30p (easiest way is to generate a universal countdown).
(2) export this video to H.264 or wmv format (audio does not affect the problem)
(3) go to the folder with the file, copy and then paste it 70 times to create 70 mp4 (or wmv) files
(4) create a new premiere project, select and drop 70 files
The length of the video clip may have some effect on whether you can reproduce this or not.
Now if you cause 22 (this number may vary) files' thumbnail to appear or be previewed, you should start to see video clips becoming solid green.
Using clips with no audio track does not solve the problem.
Turning off multicore CPU (i.e. use only 1 core) does not solve the problem, but now instead of 22 I can see 52 previews/thumbnails before the next one turns green. And if I delete 26 clips I can work with 50 clips with no problem (I could put them on a timeline and scrub around back and forth).
I turned off the other 3 cores by adding "/onecpu" to the boot.ini file.
I ended up joining the 76 mp4 files into 8 larger files using mp4box. This allows me to import those files into premiere without the green screen or hangs.
Perhaps this should be added to the premiere tips.
I reproduced the problem while checking memory usage of importprocessserver.exe. I loaded a test project with 76 files imported but NOT previewed.
The importprocessserver.exe use up about 230MB of memory. As soon as I click on the first clip (this causes its thumbnail to show in the preview window), the memory usage jumps to 743MB. Each time I click on a new clip, this process uses up additional 35MB memory. After clicking 22 files the memory usage is 1436MB and clicking on the next clip causes the green preview. Premiere process itself uses about 303MB.
