    Freezing!

    So frustrating. I'm getting random but consistent (same clip) freezing when viewing my timeline playback. I think I've fixed it but then it comes back. Video freezes but sound continues as normal. Just rendered an MP4 and the same thing has happened in the export. Any help please.

    Re: Freezing!

    What source footage are you viewing/exporting? Project settings? What hardware you are using? Need more info :-)

    Re: Freezing!

    I know I'm undergunned! Windows 7, Dual core 3ghz CPU, 4gb RAM, 1600 FSB. Was using this as a mobile DAW with 40 inputs. I know Video is thirsty. Using Studio 20 Ultimate mid range video input, transitions, titles etc created and exporting as good MP4 only. NO other programs running.

    Re: Freezing!

    First question was about the source footage.If the freeze happens in the same place each time, that must be the suspect.

    Re: Freezing!

    Thanks. Funny you should say that I was thinking about deleting and re-importing. I'll try that thanks again.

    Re: Freezing!

    If the format is incompatible, it's variable frame rate (webcam or phone) or a capture with dropped frames then reimporting is unlikely to help.

    Examining the file with mediaInfo and posting the properties may provide a clue.

    Re: Freezing!

     Re the above. 2 small phone clips from my son run fine. All other imports are from video camera files. The troublesome clips did run fine initially but from nowhere developed this freezing issue. I thought it was to do with the progress line (beige>green) updating when adjustments were being made to clips or titles.

    Really silly question. Being new to S20 my imports have created a wagonload of "bins" which are taking up a load of storage/workspace. If I delete all of my bins will my timeline content be safe? Never had to contemplate this before hence the question, I have over 2 weeks work invested in this video.

    Re: Freezing!

    So once those render bars (which are only needed for smooth preview on a slow computer) have completed, does the clip still freeze?

    Re the bins, if you delete them, the project will still be fine, but you won't be able to quickly access the clips in the library for further editing. Better to create a new bin and drag all the contents of the other bins into it, then delete the now empty bins.

    Not sure how you ended up with loads of bins. Did you create a new bin for the project?

    Yes and no! The clip plays half way then freezes for about 20 seconds while sound continues, then video resumes.

    I did create a bin but everytime I imported S20 created a new one. I guess I missed a setting when importing. I tried dragging bin contents using 2 different methods but neither worked. I've totally finished editing so don't really need them.

    BIZARRE! I think I've sussed it but will need more time as the video is 59:59:00 long. The top track in my timeline is an effects animated Dog (channel ID) which because of the speed/time parameters is in 20:14 second clips which are multiply cut and pasted for the duration. On examination the freeze occurred at  the beginning of one of these clips just 3 minutes into the project. When I checked the Dog clips either side they were 20:14, the freeze trigger clip was just 20:13. When I corrected this to 20:14 the video played as per normal with NO freezing. Now I have to find and check the rest of the video.

    I have no idea how this .01 time was clipped or why it should affect playback or rendering that is for greater minds than mine. I will let you know if this does prove to be the uniform solution.

    Re: Freezing!

    So a one frame gap in the timeline? This shouldn't normally cause a freeeze, but it certainly sounds like the culprit. let us know. What frame rate is your project? Yuor camera files are straight imports fro the camera card, or are they analogue/DV capture?

    Re: Freezing!

    Thanks. IT DEFINITELY IS! I've had to redo countless "durations" and redo freshly program created anomalies! I'm guessing that potentially ANY overlay title or similar will have the same effect. EVERY single freeze could be tracked to a .01 reduction in duration created by the program. All the videos were imported as MPG files from explorer, downloaded from the cameras. Having used S20 to download them in the first place. Framerate is 25fps.

    At 59:59 this glitch has cost me a week of my time, so much frustration that I have now given up following my most recent efforts and have published the video anyway without looking at it again.

    Re: Freezing!

    Is that 59 seconds:59 frames? I asked you what your project settings were. if you video is 25 frames a second and your project is 60 frames a second that may explain the discrepancy.

    Re: Freezing!

    No, no, no that's 59minutes 59 seconds project length @25FPS. That's 3600 seconds roughly, divided by 20 second bites = 180 items to be checked for duration after every modification or before any attempts to save or render.
