Hi,
I've just used onlocation for the first time and was very enthusiastic about the program. However, now that I try working with the files in Premiere Pro CS3, it crashes every time I try to import the mpg's from onlocation. Before crashing, if I try to scrub through the clip, it goes all jittery from side to side.
I tried importing the clips into MPEGstreamclip to re-encode, but I get only the first second of the clip, regardless of how long it actually is.
Any clues to what is going wrong?
I just press record/stop, and then eject the clips before exiting onlocation.
Many thanks,
Jon.

clip are mpg 1440x1080, 1.333 par , 1.778 dar, 25 fps at 50i tff
audio is MPEG-1 Layer 2, 48000Hz 384 kb/s tot , Stereo
seems normal to me unless I am missing something.
I forgot to mention I am using the sony v1e, in progressive mode (maybe that's messing up onlocation?)
I haven't tried saving the clips as m2t, maybe that will help.
For now, as the edit are very short, I am doing them straight in AE, which can handle them without crashing (too much), but I would love to find a way to import them into premiere, without re-encoding them.
maybe it's some timecode break problem?

Wow, tht suprises me as PPro captures as mpg too. I know m2t files work fine with PPro so give that a shot and let us know. Have you captured with PPro and does it work with those files? There's a free utility called Gspot that will tell you every little detail about a video file, and if there's a difference between the OL and PPro captured mpgs. Danny Hays

no problems with mpegs captured from tape in PP, no problems with m2ts captured from tape in HDVsplit, no problems with mpgs converted from m2ts in mpgstreamclip.
I did actually use gspot to check the details of the onlocation mpgs, but for some reason did not think about using it to check an mpeg captured in PP. Now that you mention it I can see the mpegs in PP are labled m2pt transport stream, while the onlocation ones are program streams. (not that it matters probably, but PP saves "mpeg" files, while onlocation saves "mpg")
I also rechecked a 30 sec file's stream info in MPGstreaclip and it says:
Type: MPEG program stream
Duration: 0:00:00
Data Size: 90.90 MB
Readable: 1.98 MB
Bit Rate: 23.63 Mbps
Video Tracks:
224 MPEG-2, 1440 x 1080, 16:9, 25 fps, 25.00 Mbps, upper field first
Audio Tracks:
192 MP2 stereo, 48 kHz, 384 kbps
I tried using "fix timecode breaks" but doesn't work :(

anyone has a clue why these files are corrupt, or how to fix them? how to avoid the problem reoccuring next time?
or why AE and VitualdubMod can handle them while PP and MPEGstreamclip cannot?

Using MainConcept H.264 Encoder, I saved the files as mpg transport streams, and now the clips now work in PP without crashing.
Judging by the encoding speed, the "use smart rendering if possible" option that is enabled, I'm hoping that no lossy re-encoding was performed. I don't notice any degradation in the new files, anyway.
Note that I never had problems with programs stream mpgs before in PP so I don't think that's the problem.
If anybody still has any idea how to avoid this mess in the future, please let me know.
