AVI Framerate coversion, please help

[oOGoldenSunOo]

Hi, I'm so sorry but I looked and looked but I can't seem to find a guide that helps with what I want. What I need to do is change an AVI file that is 23 fps(PAL) to an 29 fps (NTSC) AVI file. Is there anyway I can do this? Cuz the guides I look at talk about coverting VCD framerates, but I need to convert AVI framerates. It would be great if you could tell me how, or just provide a link, thank you!

23 is not pal. 25 is pal. 23.97 is film framerate. that is what movies are filmed at. what you need to do is apply 3:2 pulldown to the 23.97 movie for your dvd player to play them.

I have a similar dilemma, converting a 25 fps (PAL) .avi (and separated .wav) to a NTSC SVCD format. I have tried using besweet but I use XP and all my DOS windows terminate as soon as they are finished launching. I have considered creating a bin/cue of the PAL movie and then using the TMPGenc method of converting it to NTSC, but that would mean encoding it twice, which sucks. Any ideas?

Messing with frame rate isn't very easy, especially for newbies. First of all, I don't think 23 or 23.97 fps AVI to 29.97 fps AVI change is necessary at all. You are playing it on computer, which accepts any frame rate.

If you are converting to VCD/SVCD/DVD, changing frame rate might be mandatory, because these formates can only accept certain frame rates. You can do it with TMPG, or AVISynth. A/V sync is always a problem, if you are not careful.

You don't need to change the avi from 25fps to 29fps if your target format is is DVD. What you actually need to do is use the 25fps avi as the input video to the encoder and somehow end up with an NTSC framerate DVD.

NTSC can use 29.976fps OR 23.976fps with 3:2 pulldown. Pulldown adds flags to the 23.976fps video that tells your player to repeat certain fields in the video to achieve smooth 29.97fps playback.

There are several guides on this site and many forum threads explaining how to do this. Tak a good look around.

Let me repeat, you do NOT need to change your avi to 29fps.

You might want to consider my reply to a previous post of yours (5 June, 2003 15:34h) on the same topic. Let me add: PAL<>NTSC conversion is a whole art in itself, which in realtime can range from, in the broadcast world involve system converters from, say, Snell & Wilcox that cost upwards of $10000, down to an Aiwa multisystem, multiconverter VHS VCR that costs $600 with results that match. While to newbies it may look easy and natural, it is never an area to trifle with if even acceptable results are to be expected. It all depends on how important your delivery media is to who u will give it. If a store-bought DVD is PAL and only in that system I will accept that as a given and try to play it on PAL-capable DVD players and TVs (backups included and notwithstanding), and convince those I will give it to of the same; trying to convert it to true-blue 29.97fps NTSC will not be worth all the time & effort. On the other hand if I have made a corporate video and am required to distribute it to different branches of x company worldwide then it has to legitimately be in both true PAL and NTSC DVDs, and so far with DV AVI material (that make the bulk of my captures and NLEs) the best cost-to-performance ratio, IMHO, is met only by aDVanced PAL/NTSC converter from www.dvunlimited.com.

Only two posts ever made on this board and both reccomending a single product. Be careful, you might be accused of advertising which is a strict no-no

[turk690]

I'm sorry if recommending a single product is how it appeared. It's just that I couldn't contain my joy at finally being liberated from the confines of creating only PAL DVDs from my PAL DV sources, finally being able to produce true NTSC DVDs as well with quality infinitely better compared with those obtained through procedures that involve TMPGenc, for one.

turk 690 - I want to go from mpgs/VCDs at 29.97(NTSC) to PAL(25fps) since although my new DVD player can play everything, my crappy portable TV only bought about a year ago can only play PAL.

I've tried to follow the numerous guides and have ended up more confused.

I have 2 options:

1. Buy a NTSC to PAL converter box for about £35 to let me play the NTSC stuff on my PAL TV or

2. tryt The program you recommend DVunlimited?

Which do you reckon would be the easier option?


Cheers
