Using the filmstrip style there's a glitch appearing in Capture.

The album .vexe was ok and ran fine but whilst converting it to a video file theres an error as the 3rd strip of film comes in (the 1st vertical strip) and again just before its gone.

The problem is the top of the vertical film strip flashing onto screen for a 1/100th of a second just before the "real" strip comes in.
It happens again as that strip has nearly gone.

OK, could someone please explain fps to me.

I thought it meant frames per second, and therefore one second of video would include 25 "picture" frames per second.
If that's the case, how is it possible to edit out 1/100 of a second of video?

I've just done it twice and got rid of the above glitch to perfection, but i'm confused. Assuming the glitch is on 1/100 of a second of video, are there 4 frames to 1 frame, if you know what i mean? Very Happy

What exactly did i edit out Confused

It is my understanding that fps means frames per second. NTSC uses 29.97 frames per second and PAL uses 25 frames per second.

I haven't tried editing out individual frames using CS. I do that in my video editor where it shows the time in hours:minutes:seconds.frame number. Being able to step through a video clip frame by frame makes it easy to find and delete a frame or frames that are causing an undesireable effect.

I used ulead VS9 which shows the time down to 1/100 of a second, which is precisely how much i cut out.

I cut the video into 3 sections.
0 - 34.07 secs, 34.09 - 48.15 secs and 48.17secs to the end.
I would have thought the glitchs would cover 1/25 of a second at least(PAL), or a full "frame".

I'm glad it doesnt because the edit would be noticable i expect.

That's an interesting approach. It never occured to me to try and cut a frame in half. I guess that is because in NTSC I've never noticed removing one frame was noticable unless that frame contained a glaring bad spot. My most common thing has been in editing video taken where other folks were using still cameras with flash. I edit out the frames where the flash has caused the scene to be washed out. Usually it is just one frame for each instance where the flash went off. In the final result I do not see any noticable difference as far as the movement or the sound.

I'm curious as to how Ulead handles a partial frame.

Andz, the times you give aren't "100th" of a second, they are frames. Pretty much all editing programs will cut on the frame; some older linear video editors will cut on the field (1/2 frame).

Step through any clip one frame at a time. Does the last two digits go from xx.29 to xx.00 to xx.01? If so, these are frames, 30 frames to the second, (despite the "official" 29.97 frames per second rate).

Oh for god sake,,,,,,,,,,my mistake again Laughing

Yeah sorry, i've just noticed it stops counting at 24 and goes to zero. I just assumed because the numbers were next to the hours, minutes and seconds counter they were 100th's.

Another lesson learned Very Happy

Andz,

One other thing. You are using 25 FPS. This is a PAL setting. NTSC DVD uses 29.7 FPS (30 FPS).

Your profile doesn't indicate what part of the world you live in. If you are in North America, best to use NTSC. If in Europe, PAL. Some parts of Asia use both.

Your profile doesn't indicate your location. Therefore, make sure you are using the right format for your part of the world.

I'm in the UK Michael ~ PAL 25 fps.

Most of the time i know what i'm doing, or think i do, but every now and then something comes along which confuses me ..lol

Andz,

Makes sense now.

I do a lot of business in the U.K., and produce video in both PAL and NTSC. While I use expensive workstations and complex video editing programs for most commercial work, my staff and I also use high end PC's with entry level video editors like Ulead's Studio9. I think you will be very pleased with its capabilites. When combined with 3D Album, 3D Time, and various other 3rd party utilities, you will be able to produce very meaningful work.

Cheers
