Unusual fps conversion (20 fps to 29.97)

[Heflink]

I come with help for anyone who has ever dl'd a divx clip that had some odd fps. I had this happen to me two days ago when I wanted to convert a Divx (I think 3.1) to a VCD that I had just downloaded. But it appeared that whoever authored it set the fps to 20. I scoured google and Vcdhelp trying to figure out how to deal with this.

After days of searching, my mind left numb and barely sentient, I found someone here (maybe not this particular forum) saying that to convert you simply need to speed up the Audio with CoolEdit then when TMPGEnc speeds up the framerate to comensate it will all be in sync.. This was not very much fun to do and it sounded sped up (ie. like crap).

Much time spent typing and clicking later (my body now famished and gasping for fresh air) I figured out a very easy way of doing this.

(note: All of this wasn't so much "figured out" as was "read in help file")

In Adobe Premier I opened the divx file, I placed it on the timeline. I Selected
Clip>Video Options>Frame Hold
Here you can set the fps to whatever you want but it defaults to NTSC so it doesnt really matter that much. Then File>Export Timeline>Movie.
Make sure before you save the file you click settings and Edit the video settings so you have a Divx (or some other Codec) selected, otherwise the file will amass to much more room then my HD has.

After that I did the usual Divx to VCD hooplah with TMPGEnc and it's right as rain, looks beautiful.

Well I hope this isn't me just telling everyone here something they already know, and it actually saves someone a lot of time, and/or quality.

Doesn't this simply re-encode the avi (in divx or whatever codec you selected)?

[Heflink]

No, in fact you dont have to compress the file at all (which I found out the hard way). And if you did simply re encode the file with a Divx Codec it would still be in 20 fps. Adobe Premier changes the framerate, and quite unnoticably as well, though I did realize that your frame rate has to be either 29.97 or a two digit number (so you could never convert to NTSC Film) but it would work for PAL to NTSC and vice versa nicely.

[secretagent]

all you have to do is open file in vdub and frameserve it to tmpgenc and it will encode to any template ntsc film, pal or whatever

[Heflink]

When you do that all the program converts it simply by playing the movie faster.. then the audio gets slowly out of sync.

[secretagent]

audio will not get out of sync if you put the audiio in full processing mode then choose conversion and use 44100, 16 bit hiquality stereo

[DivXExpert]

Yes is will. The video is playing faster than the audio.

audio will still get out of sync even if you put the audio in full processing mode then choose conversion and use 44100. VD

i tried that. but my problem is slightly different, frame rate is 29/s. thanks for the suggestion, Heflink.
