FRAMERATE CONVERSION????

[comet_104]

Hey ya'll:

Do I need to do a framerate conversion if I have an avi file with a framerate of 14 frames/sec? I wonder if I need to convert it to 23 ro 25 before I encode it to NTSC. I tried asking this question earlier on the newby forum and someone was nice enough to direct me to some help topics on this site which I read, but it didn't answer my question.

Thanks,

Comet

VirtualDub

open the avi
VIDEO -> FRAME RATE -> CHANGE IT TO THE RIGHT FRAME RATE
OK
FILE -> SAVE AS AVI
done

I know you were looking for a simple answer but with an fps that low I'm not sure one exists.

Certain framerate conversions work better in vdub because it speeds up or slows down the playback speed, rather than adding or removing frames like what TMPGenc can do. However in this case if you sped 14fps up to even 23.976fps then I think it would be completely unwatchable. Everything would move so fast that it would just look silly.

I would suggest one of two things. First, try encoding a sample in TMPGenc with the framerate set at 23.976fps. Burn a test disk and view it on your dvd player and see if the quality is acceptable, because I can assure you that the playback is going to be very choppy. You need to actually test it on a hardware player, not a software player because it will perform the necessary telecine to 29.97fps.

If the quality is unacceptable, which I suspect it probably will be, then try using the 15fps internal (played back at 30fps) framerate option in TMPGenc. (It's named something like that, I'm doing this from memory. This will create a non-standard disk but, there is a good chance that if your dvd player supports it, you will actually have very smooth and acceptable playback.

The audio is another concern, and ultimately might be what makes this project futile. When you speed the audio up, in this case its going to be running twice as fast, you also increase the pitch. With this conversion your audio is literally going to sound like Alvin and the Chipmunks. All you can do is lower the pitch manually to offset this but then, in your case, it will probably sound demonic.

Give it a shot and see if you can handle the choppy playback and strange audio effects. You may want to consider just watching this on your pc and finding a better source to make a vcd with.

Hi Adam:

I think you are right. Maybe I'll find a better source of avi files. Got any suggestions where I could possibly down load them from? Maybe a website that I can join and pay a monthly fee instead of kazaa where I get them?

Thanks,

Sorry, these things should not be discussed on this board.

Hello:

Sorry..no problem. I'll remember that in the future.

Thanks again,

I too converted a 14 fps movie, but i just did standard vcd in tmpge @29fps and it worked. No speeding up of anything.Of course it looks shitty,but wut do you expect with a movie filmed in a theatre with video camera them downloaded off kazaa. It was watchable though,like i lived in the 50's or somethin

hello:

I wonder if all of the 14fps movies are filmed in the theatre with a camcorder like that? I had one that worked..but mine looked crappy also and I thought maybe it was because I needed to convert the frame rates? When you download these movies what is the best format to download them in so that you can convert them to a good vcd/svcd format?

Thanks,
