    Hi guys,

    I was wondering if anyone else is has this occur? I just noticed that if recording MP4 (1080p60) the videos are being clipped short by about 2-3 secs.

    In AVCHD (1080p60) the same occurs but only about half a second.

    Just a warning that if you are recording speech, don't button off right away, keep recording for a few more seconds or you might you lose the end :(

    Strange! Cutting off at the front is common but not on the tail end.

    Strange indeed. Does anyone else have this issue?

    Easy way to test yours: Film a static shot for 5 secs then quickly re-frame for a further 2 seconds, then stop recording. Check the recorded clip to see if the second shot is there.

    Perhaps it's something a firmware update can fix.

    As a matter of course I always "pre-roll" for about 5-10 seconds before calling "action" and I always let it roll about the same before calling "cut". Gives a bit of room for transitions at both ends and much more freedom in the editing process.

    Good suggestion and is standard procedure for on set filming BUT it doesn't work that way for shooting the kid's birthday party or what have you.

    Can anybody else confirm this is happening with theirs? I'd like to know if my camera is faulty. Thanks in advance.

    There is a slight delay between hitting the shutter button to stop recording, and the beep that says it stopped, so its hard to be sure, but I'm certainly not losing 2 seconds. It seems to stop right when I press the button, but when operating the camera it doesn't appear to stop for about a half a second. Tested both MP4 and AVCHD. Maybe I lost a half second to a second... but just maybe. Again, its hard to tell just by playing with it in my living room.

    Thank you.
    On mine, if I hit record, count to 5 out loud slowly, then hit stop, the resulting video only makes it to "three" then cuts out. It's kind of annoying.
    Recording mp4 1080p60.

    If it is still under warranty I would send it in for service. I have used a lot of video cameras and have never seen it cut on the tail end of the video.

    My OM-D E-M5 does the same thing!!! (Cuts the end short by a second or two). It's really annoying!

    Interesting. Well I suppose it's not that big a deal, as long as you keep rolling for a few seconds after your intended shot. Or shoot using the AVCHD codec, which on the GX7 seems to not suffer this problem as badly.

    Yeah, that's the easy solution...except, usually when I'm shooting, I forget that it's going to get clipped if I stop it at the proper time.

    I just tried again, counting "One-one thousand, two-one thousand...." and hitting the shutter button right after "five-one thousand". On both MP4 and AVCHD it cuts out at "Five-one", so I lose about a half second.

    Could this be related to the SD card write speed?

    Most recommend at least a Class 10 card for video.

    It is possible. I just tried it on my E-P3 with a class 4 card and it cut off the last second but it didn't do it with a class 10 card. So it does seem that the write speed of the card does have some part of this. Yes for HD video it is best to use class 10 cards.

    I'm using SanDisk Extreme 32GB Class 10 cards...shouldn't be an issue...

    Same here, Class 10 sandisk. Consistent 2 seconds missing from end of movies.

    Also, I just had a VERY long lag (5+ secs) opening the playback screen. For a brand new camera this thing seems super laggy. Will see how the performance goes over the next week but it looks like I might have to take this one in for warranty. Firmware is current and up to date, for anyone who is wondering if that was the issue.

    Not quite the same problem, but I just made a stupid little stop motion film, 326 frames, 25fps, 13 seconds. Have to save as mp4.

    It plays back in full in-camera, in Lightroom and in Windows movie maker, but in VLC player, although the length is given as 0.13 it cuts off the last bit. And the jelly baby doesn't fall off the table.

    What if you export the clip from LR? is it still shortened?
