I use a intel i7 notebook with a geforce GT 635m graphics adapter.
PrPro CS6 is not able to render smoothly the sony avchd (*mts) material shot with my sony nex vg50. Changing the resolution does not change anything.
There is no problem for ex. with stuff like xdcam ex or using mpeg 2.
GPU processing is activated, but also using software renderer does not change anything.
The sequence shows a green line, so nothing has to be rendered in advance, but playing back the timeline does not work smoothly.
Has anybody specific experience editing stuff shot with a nex?
Thank you for your support
The method of import can sometimes affect how certain codecs perform in Premiere. The best method is to copy the entire contents of the camera memory card to the edit computer hard drive. Do not modify that data at all; do not use Sony Transfer utility, and be sure to copy entire folder structure. Then in Premiere, use the "Media Browser" panel to Import the footage, rather than "File > Import". This ensures that Premiere will correctly interpret the format being imported.
Hope this helps

I think this could be the right idea. All files were copied to the hard dive using Prelude CS6 to avoid errors concerning the metadata structure of the avchd files. But I always used "import" to get the files into the project. Checking now the files using Media Browser inside Premiere Pro, I found not even one directory, where Media Browser recognized "AVCHD", but only "data directory" (=transl. for german "datenverzeichnis"). Therefore I guess the metadata structure of the files was corrupted while transmitting data from the memory-chip. I will check it tomorrow and give you an instant reply if I succeeded.
checked it already, but there was no difference. Now Premiere Pro recognizes the files as AVCHD, but importing them through Media Browser does not change anything. The file play constantly within the preview monitor, but arranging them into the timeline causes severe problems. Constant Playback is not possible. What can I do now?
(Additon: I use the latest available version of PPro CS6 (6.0.5).
HD = SSD internal
Sequence Preview: Change it from FullHD to SD (PAL). No changes.

Is Mercury Hardware Acceleration enabled on the notebook? This is critical for performance. Note that the display card must have at least 1GB RAM for this to work, then even if not on Adobe approved list, it should work. First thing to do is update the Nvidia driver for the display card, as factory installed driver is usually very out of date. Do that, and then find the Programs/Adobe/Premiere folder on C: drive and look for "cuda_supported_cards.txt" file and rename that file, add "backup" to the name or something.
The other thing is that whether on a laptop or desktop, one should never use the C: drive for video storage, always recommended to use a fast, dedicated drive. If external, USB 2.0 is too slow, look for USB 3.0, or eSATA or Firewire for instance.
You mentioned the timeline being green, that suggests that you had rendered the timeline (hitting enter key does that). What is the Preview codec set to?

Mercury Hardware is enabled, the Graphics card comes along with 2GB of RAM. But nevertheless I tried the software renderer without any difference. The Nvidia dirver is up to date, which causes by the way some trouble, because ASUS provides their own driver. But now the driver works properly (think so). As far as the Mercury Engine works you can see, that cuda is supported. I checked it also with cuda disabled and renaming the txt-file with the supported cuda display cards. But this does not change anything.
I work on this notebook with a internal ssd-drive, but this drive is only for editing-purposes. I checked now also an external USB 3.0 drive, without any difference.
So I do nat have any idea what can cause the troubles. As remarked above, it is a bit strange that every clip I copy into the timeline was marked with a green line. Normally that means the stuff has to be rendered, but rendering was already done. Normally I expect, that no line has to appear. But: I know this behaviour already from a lot of editing work I did with XDCAM EX-stuff. Sometimes there appears also a green line, but this does not effect the performance of replay in any way. Also the NEX material (*.mts) runs properly in the preview-monitor, so I can not imagine that it is a problem of the codec itself or its implementation.
Thank you for your support.
The preview codec is MPEG I-frame. I tried it with different resolutions. No difference.
Of course the green line means, that a clip has been rendered. But in the moment I insert the clip into the timeline it was marked with the green line (not red). And that means, that rendering was finished in the moment I insert the clip into the timeline.
I am really thankful for your input, because I am really a bit desperate for the moment. It would be very helpful, if anybody could confirm that working with sony *mts-files shot with a nex works properly inside premiere pro CS6.
I would expect that format to work fine, even on some older systems.
I'm thinking this may be a hard drive issue. Laptops are not the best option for editing. Ideally you want a minimum of five internal drives for best performance.
Thanks for staying with me.
I will check this matter on my professional editing machine with two Raid 5-Storages attached, each with 8 Hard Disks inside. But of course I do not expect any difference. I work on the notebook normally with XDCAM EX material encoded with 35mb/s (720/50p) or MOV-Files (H.264/38mb/s) shot with a Canon 5D. I never have had to face these problems. Sony AVCHD 2.0 stuff was encoded with 24mb/s. So I expect, the storage will not have a problem. Nevertheless the strange behaviour points into this direction. The stuff works fine playing it inside the preview window. The problem occurs when I copy some clips into the timeline. This could be a hardware issue (HD) or a problem with the Codec itself. If I copy six clips to the timeline, each 10s long and I start playback of the timeline from the beginning, the video starts to be jerky from the 2nd. or 3rd. clip onwards. If I start the playback from the middle of the 5th clip, the playback of the 6th clip ist quite normal. So the playback performance depends from the number (not the length) of clips that have to be played. I think the reason could also be a problem with finding an In-Point for Premiere into AVCHD-stuff shot with a Nex.
