VideoStudio 12 temporarilly freezes during project playback

Post by barrydauber1 »

Describe your problem: While I am trying to playback in Project mode to review clip, title, music edits, the program will freeze for a while. It does come back to life a few seconds or a couple minutes later. If I keep clicking, then I get "Not Responding." It seems more common when playing back videos with titles or music. I am able to render the project to files and DVD's successfully. It's just that editing gets very tedious with the freezes.

I installed the program last month with the DirectX updates and Patch 1.

The computer is an HP a6720f with Vista 64, AMD 9550 Quad-Core 2.2 GHz, 6.0 GB RAM, nVidia GForce 9100 video card.

Properties of your source files, including video, audio, image files (format, file size, where did you get it?): Two videos from Kodak digital camera - MOV format. Each video is about 25 MB. About 300 JPG pictures, each about 1.1 MB for a slide show. Audio is portions of six WAV songs. Each song is about 25 MB, but there is probably only half of the songs on there.

What devices are involved and their mode of connection?: No external devices are connected to computer.

Project Properties (important): NTSC drop frame (29.97 fps)
MPEG files
24 bits, 720 x 480, 29.97 fps
Lower Field First
(DVD-NTSC), 16:9
Video data rate: Variable (Max. 8000 kbps)
LPCM Audio, 48000 Hz, Stereo

Output format (file, DVD, VCD, SVCD): DVD

Output Properties (cogwheel in lower left of burn screen): NTSC drop frame (29.97 fps)
MPEG files
24 bits, 720 x 480, 29.97 fps
Lower Field First
(DVD-NTSC), 16:9
Video data rate: Variable (Max. 8000 kbps)
LPCM Audio, 48000 Hz, Stereo

PAL or NTSC: NTSC

Error Codes (if any): None

Product Version: VS 12.0.98.1 Pro

It's probably your MOV file. (Video Studio has trouble with some files, and the more-compressed formats tend to cause the most trouble.*)

Usually, the only solution is to convert to another format (i.e. MPEG-2 or DV/AVI**) before editing. Open the MOV files one at a time and save-as MPEG-2 or DV/AVI before editing. Then open & edit the new files.

If you can't do that without freezing/crashing, you can use a 3rd-party program like SUPER (FREE!!!) to convert the files first.



* It could also be a problem with one or more of your stills, or one or more of the audio files, but MOV is the most-likely suspect.

** DV/AVI (13Gb per hour) is less-compressed and is the most trouble-free format. But, since you're making a DVD, it will need to be converted to MPEG-2 eventually anyway. If you choose DVD-compatible settings (like your output settings) you can check the box that says Do Not Convert Compliant MPEGs. This will preserve quality and save time during the render/burn stage.

EDIT: I see that DVDDoug beat me to the punch, but I will leave my post as it is as it is not inconsistent with Doug's advice...

Hi Barry -- welcome to the forums! :lol:

I think we need to start off with a few home truths... First -- Video editing is tedious, period! :wink: That's probably why we masochistic types like it so much!!! :lol: :lol:

Second, not unrelated to the above, is that you have to be patient with Video Studio. It does not like to be 'pushed'. In other words, clicking repeatedly, as you have found, will only cause the program to freeze and/or crash. So just give it time.

Playback in Project mode means that the program is trying to hastily put together all your material and edits and play them back in real time, and this can take a little while and imposes considerable demand even on a powerful computer such as yours. But check in Preferences > General to make sure you have chosen Instant Playback, instead of High Quality Playback, in Playback Method. The latter can slow things down considerably further...

Third, the video you are using is .mov and VS seems to have a particular dislike of that format. Or should I say formats? That is because .mov is just a wrapper extension which covers a variety of video formats used in digital still cameras such as yours. Kodak often uses the MJPEG codec (Motion JPEG) but disguises it as .mov. But other cameras will also use mpeg-4 and a new high definition format, AVCHD-Lite (which VS was never written to work with). You will need to right click on one of your .mov files, please, either in the timeline or library window of VS, and copy down all its Properties here. That way we will have a better idea of exactly which codec is involved.

But one alternative is to use a third party conversion program such as the freeware program SUPER (www.erightsoft.com/SUPER.html ) to convert the .mov to a format which VS prefers. Given that you are producing a DVD, I would convert it to DVD-compatible mpeg-2 with similar properties to those of your Project and output. Using this mpeg-2 in your project could also speed things up a bit in Project playback.

Overall, however, given that you say you can produce your DVDs OK, I would say that you just have to be a bit patient if none of the above things I have suggested speed things up much. I too have a Quad and I know you think things should be faster with such a beast. But I guess I have been editing long enough to know when it is time to go make a cup of coffee and let VS do its thing at its own speed. :wink: :lol:
