Dropped frames.do you have answers?

[skychic68 0]

With dropped frames all over the place, what is a person to do????? I have reinstalled the program and I think all my settings are correct. What the hell!!! (ADS PYRO PRO with Media Studio)

I can't get a clean capture for nothin'.

Any suggestions??

Burn the application, perhaps!!!! Ergo, the need for a better computer....or will this do the trick?

That's it, I'm going to computer school!!!!!!

What OS are you using?
What kind of processor?
How much RAM do you have?


With my original editing software, I had to enable DMA (direct memory access) to keep up with the high data rate.

I don't have the answer to your problem, but I bet the above questions will help someone help you.

I have a few more questions:

on top of what OS you're running ...
and what CPU you're using (type and speed)
What kind of Harddrive are you using ? and are you using different harddrives for capturing footage, and diferent harddrive for your OS and applications ?

there are alot of factors in NLE that can cause dropped frame, let us know what you've got, and we'll let you know where you might wanna put some efforts into.

I use AVID, and I have had similar problems. It ended up being linked to unsupported Firewire hardware (not AVID certified).

Don't have a clue if your NLE has a supported hardware list, but if so, I would consult it.

Additionally, make sure to check the support website for patches and conflicts. I spent a few days trying to debug a problem that turned out to be a Windows XP security update issue -- AVID wouldn't work with the update, so I had to back it out (and stay vulnerable )

EDITED TO ADD:
Just thought of other issues to check -- be sure to separate your system drive (with virtual memory files) from your footage drive.

And shut down any or all other unnecessary programs while running the NLE program.

A few regular things to try out.
Go to the canopus site and download 'raptest', install it and check your hard drive read write speed.
you should be sustaining at least 5mb/s
http://www.canopus.com/US/products/free_utilities/pm_free_utilities.asp
Google for 'enditall' use that to shutdown background applications.
Make sure you are writing the captured files to a separate partition, or a different physical disc to your one housing your applications and o/s.
Empty your recycle bins and defragment your storage hard drive.

Run a head cleaner in your camera once or twice. We get dropped frames in Premiere after a few weeks on the TRV20 we use for capturing. Once through with a miniDV head cleaner stops the problem, most time. Otherwise, the camera person's camcorder (needing cleaning) or lousy tape (Maxell, for instance) tend to be to blame.

i would also add that they way you capture footage can lead to dropped frames. If you capture from one start-stop sequence to another, and have left space on the tape, then capturing over this "gap" can lead to dropped frames. Best thing to do is try to work out what instance is causing the dropped frames and work from there - easier said than done i know, but that's the best advice i can give really

One other thing on that thread: Many NLEs can compensate with jogged timecodes (that go back and forth) with assemle-edited footage on a tape, however, all the ones that I have used will have a problem with no-timecode footage (e.g. you have a gap in footage on a blank tape).

Best solution is to put timecode on a blank tape before use. That way if you have an 2 or 3 frame gap, it will use the timecode on the tape that you dubbed previously. Easiest way is to set the camera up, and record from beginning to end on the tape.

yup i forgot to add this to my post - good point. Always "black" your tapes before hand like jm said (just hit record and tape the entire cassette with the lens cap on)

When I think about it, I try to blank it with a picture of clouds or a skydiving bumpersticker or something. That way, if I mis-cue a tape while shooting a tandem video, it doesn't look as much like a screwup..

thats a cool idea. I dont even wear a camera at the moment, but i'll bear that in mind when i start shooting for others.
You could always do a "Fight Club" and black the tape to a porn pic or something and give them the odd 1 frame of some of the other kind of "tandem" video

I'll try all the suggestions here. But I'm inclined to believe that the dropped frames are due to my slow processor. Who the hell knows. I will keep at it. What about transfering video to PC via USB. Perhaps trying this would be better for the slower processor speed?????

Que sera sera

[skychic68 0]

You know, I'm in the process of getting a quote for a custom built desktop. Hopefully with a faster processor and all the video setup I could possible want will at least settle many of the issues I have.

I will, however, in the meatime try these suggestions. I sure hope something will work. It's especiialy difficult when your knowledge base is very slim when it comes to these issues.

What are the specs of your current machine?

I manage fairly well on a PIII 450 (not overclocked), ADS Pyro & Sony PC101 with zero dropped frames but I have to capture with premier 6.0 and edit with Premier 6.5. I have a separate 7200RPM hard drive for capturing. I shut down every other application and tread carefully but it can be done. I wouldn't bother with anything slower than mine but any newer machine should be very straight forward. Search in Google groups ("rec.video.desktop" is a good start) for "dropped frames" and you'll have better luck.

"What about transfering video to PC via USB"

USB is way too slow for full res minidv editing, plus very few cams have a USB (USB2?) connection that will spit out decent quality video.
As for machine specs....I have produced two formal movies on a system with a PII 266 on Prem 4.2, though I dunno what the current minimum specs are for Prem 6.

I think specs for newer versions of Premiere are more stringent.

As far as the dropped frames, well, I am having other issues in other programs as well. I am having a quote done for me by a guy I work with who builds puters. He's really going to hook me up. I need updates so badly.
Check this out:

P4 at 2.6 GHZs478 800 front bus
Intel 865 GLCLK 800 mhz (includes extreme graphics 64 mb onboard)
512 MB memory
7200RPM
DVD ROM
4x DVD+R/2x+RW
and some other little things

Beats the Plll at 500 I'm running on now

watcha think?

Que sera sera

[skychic68 0]

Take a look in the thread to see my specs. I'm going to be getting updated, you know, living in the present. HOOORAY!!!!

It sure costs big bucks to keep up witht he Jones'.

Perhaps with a new system I won't have to deal with as many glitches in the programs.

If your buying a new computer mostly for the purpose of video editing then buy a mac!!
An emac for example is much much better then any windows machine http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/70803/wo/8M667DtrJ10w3F8IeeW1BOJb9FO/0.0.7.1.0.5.21.1.2.1.0.0.0.1.0

[nacmacfeegle 0]

When the dude builds your new pooter, keep te old one for post whoring, and other non-video work.
Use the new one for editing only, and be careful what you put on it, eg Find Fast which comes with MS Office will slow up your system........

With the specs you have in mind, that should be able to run real time cards, if your taking this really seriously.

[kallend 1,920]

Here's another question for the experts:

I took a video of a ride in a Stearman biplane. The capture (TRV33 - firewire - Premiere 6.5) works fine up until the point that the engine noise gets very loud, then it starts dropping frames all over the place.

What's with that????

...

The only sure way to survive a canopy collision is not to have one.

[d15859 0]

Kallend,
I have heard that the microphone can get too much input,(sound) and can cause a type of feedback internally in the camera....I also have a TRV33,and just last weekend stuffed the bonehead box full of foam around the microphone area. made quite a difference, you can still hear just fine, but it's toned down quite a bit. Might just help...

Skychic;
I Just installed a Canopus AVDC1394 card with the front bay inputs, works really good. The hook ups are much easier now too being in front! So I suggest a good capture card as well as a good video, (Graphics) card, they are different but work together. Also get as much RAM as you can afford, 512 is thin, get a Gig if you can.

[skychic68 0]

I'll see if 512 is enough for now. I can always add on. My co-worker can get parts at wholesale.

I think I'm gunna like my new set-up

FAST>>>>>>>>>>>>>>

Where on your shell does the firewire install in the front?

Que sera sera

[d15859 0]

It sets in one of the front bays that you are not using..., has a fire wire, S-Video,(anaolog) and the usual RCA plugs. Check out canopus.com they have some pictures there.
