One of my friend wants to take some WP transfered 8mm footage as dv-avi to USA and edit it there. I use Dodcap and captured today a short R8-example using NTSC 18 fps -option in Dodcap. I'd be happy to know, if it's possible to use this avi for videoediting.
This is from 1967 and there is some computer equipments, filmed in Helsinki. Quality of these pictures is bad because the original film is very underexposed.

Here is one still picture from the original capture (238 KB):

From Pal-environment to NTSC?
Moderator: Andreas Wideroe
I didn't get answers to my NTSC question...
Perhaps it's not so easy to get ntsc ready material straight from Pal system. I found some PAL-NTSC converters but they are fairly expensive (aDVantage PAL/NTSC Converter, Canopus DVFormat Converter...).
How about still pictures? It seems to be not possible to get still frames straight from Dodcap, but I can import Dodcap-avi for instance to iMovie and then export numbered bmps, jpegs or pngs (and burn them to dvd). It might be easy to make ntsc avi from stills. This seems to be good solution if you are not sure about ready made avi:s.

I'm suprised nobody has answered you.
My suspicion is that this will work just fine!
If you have captured it into the computer asNTSC then presumably it is now an ntsc file and will work on ntsc based systems.
I guess the file would need to be tested on an ntsc tv and maybe that is why people are nervous to say it would work.
I think the computers themselves are fairly agnostic about tv system.
Certainly if it didn't work then it could be transcoded digitally. Most mpeg converters can go from pal to ntsc and vis a viz.
You could try importing your NTSC clip as Pal into an NLE or as NTSC and see what happens in both instances?

Hey Atta,
I haven't answered before because I know nothing of Dodcap.
I have, however, experimented with PAL to NTSC conversion.
What framerate is the avi you got from the capture?
Most software converters are crap, even expensive ones. Best results I got was with Twixtor's plug in for After effects, but I wasn't pleased with the results, eventhough Mattias tried hard to help me.
There's a demo on the web, sp you moght try that.
If Dodcap can capture 29.97, 23.96 fps or even 24 you'll be allright, and the conversion is smooth. If 25 fps is your only solution, the motion will most likely jump.
Again, I know nothing of Dodcap. So what are the possibilities according to framerate?
Cheers

It's originally 25 fps. In Dodcap there are 15,18 and 24 fps pulldown options on NTSC video. Petteri (active member in this forum too) told that AviSynth + VirtualDub can make this conversion well. I'll try them later. Jukka Sillanpaa recommended the use of Raptoredit if you have still frames as source material.sunrise wrote:Hey Atta,

I see I don't really understand the differences between these systems and what is needed if you want to edit wp transfered pal footage with ntsc NLE... I found many different comments about this question and someone saw it very problematic: "The big(gest) problem in standard conversion is good motion interpolation--how to convert 25 frames to 30 or vice-versa. Some very sophisticated and expensive machinery is needed to do this process well."
To Freya:
This footage was from my father, so there were no copyright problems
The original is longer but because of the space avi needs I cropped it ...Atta,
as I understand Dodcap it is not concerned with framerate. This means that you can capture to any framerate you like and change it within the program.
Was the original footage 25fps, 24fps or 18 fps?
Anyway, capture at 25 fps, so that you'll have a frame accurate transfer (1 filmframe = 1 videoframe). You can then change the speed and use the 18 or 24 pulldown in NTSC.
The only real problem with conversions between PAL and NTSC is the framerate. Because of the frame rate you cannot get a frame accurate conversion. Some software let's you do the conversion with interpolation, but they are not very good.
For best result you should go to a post house and run it through a hardware converter, but that's if the budget allows it.

Perhaps it's then better to let the avis be as they are (25 fps) and leave the conversion problem to editor in USA

Hi,
Just got back. My PC system is NTSC avi or analog. However my set has the Panasonic DV Codec, so, Premiere can use your file, as well as Virtual Dub.
Your file has some frame doubling, that is, not every frame is unique.
I capture using VidCap and get an avi file that contains every frame unique. Then I adjust the speed in Premiere.
I don't have much experience with DV, but, it plays and edits easily in Premiere 5.1 with the Panasonic DV codec.

Thanks Michael! Good to know. I can then work as I planned.regular8mm wrote:Hi,

Pal
Hmmmmm
Perhaps I [i]could[/i] use a Pal camera.
Here is a ntsc mpg dv TMPGEnc conversion of your source made according to Mattia's instructions.
