Does anybody know the best/easiest way to transcode a quicktime movie to a divx5 movie? It must be possible, no?

Best? Easiest? That's open to interpretation. Try searching on "quicktime" or "mov" and see what pops up.

I've done it when necessary, using RAD Video Tools and Virtual Dub.

I'm sure that you'll be able to find additional methods.

it is possible using avisynth to frameserve to vdub.the avs script need to be told the fps though.and you need to have quicktime player installed because it installs the codecs that qt uses.

eg

DirectShowSource("C:\yourmovie.mov",29.97fps)

Another method that I've used to convert the Spiderman Trailers and some Fan Films with, requires you to have QuickTime Pro. You can load the QT file, export the movie as an uncompressed avi then use VDub to make a Divx file. This may not work with files bigger than a trailer as the uncompressed avi files are HUGE. You can also extract video streams and audio streams from QT files. I've tried other methods but this is the way I've had the most success and best quality of conversion.

The easiest way I have found was to is use the TMPGenc QTreader (http://www.dvd-digest.tv/downloads/files/encode/QTReader.zip).
Then open the mov in TMPGenc, File->Output to file->AVI file and encode as you would anything else. (Just so you know, the box for selecting the codec is almost cut off, but you can see part of the left side, click on that to choose a codec)
The best part of this is there is no intermediate uncompressed avi.

Frameserving with avisynth do I need an input plugin for avisynth to make it compatible with quicktime? Also how do I find out about the framerate?

no plugin needed.to find the frame rate in qicktime you need the pro version.if you have the latest tmpegenc and qt reader and open it with the wizard it should tell you the rate.most trailers are low frame rate like 12fps.
Getting the audio is more difficult.but is easy if you have the pro version.just use the "export"function under"file"menu.
sorry i can't be more help as i don't have qt installed and can't remember all the options.
media player 6.4 should play qt files if qt is installed.it can tell you the frame rate if you right click on the playback screen and select the video renderer under properties.

I've tried this, but it doesn't work, Although I have installed quicktime 5.0.2 pro & windows media player 6.4

Only some quicktime files work with DirectShowSource, I don't think Sorenson video works with AviSynth, which is probably what the file is.

I have another problem, I used the tmpegenc way, but while quicktime says it's a 24 fps source, when using tmpegenc it encodes it as a 60 fps source!

What should I do about this?

Under settings change the framerate to whatever Quicktime says it is.

LoadVFAPIPlugin("C:\QTReader\QTReader.vfp", "QTReader")
QTReader("C:\quicktime.mov")
ConvertToYUY2()
FlipVertical()
SelectEvery(25,1)

That's what I use. You need to download the QTReader plugin for avisynth though. it's in the downloads section. If you fast recompress quality-based 100%, you'll have a nearly lossless conversion, at about the same size.

ConvertToYUY2()
FlipVertical()
SelectEvery(25,1)

why are these necessary?

Also will this take care of a good framerate automatticaly?

Two problems with that, it costs money(or is illegal), and you have to create an intermediate AVI.

CharlyAR

Well, about expensive of illegal... let's say that I have no comments.

About the intermediate .avi, maybe i'm wrong, but i think that you can export directly to divx codec.

Sorry guys, but, isn't it easyer, and maybe even better to convert the Quicktime format using the Quicktime Software???

If you go to File -> Export (Ctrl-E), you can export the movie to a standard avi file...

Carlos.

Nope. Limited compression options, no DivX codec. For audio, you have a choice of aLaw or uLaw. I'd much rather do a -V 0 of the audio in lame, to make sure it's less lossy. Chaos, who knows. It seems to work, though.

I'm using the settings you gave me, but I would really like more info about the selectevery thing (because the info on the avisynth site is hard to understand)

Here is a guide by Nicky (@ digital-digest) that works with any codec, it's free and you don't need to install any crapy quickTime software here (http://nickyguides.digital-digest.com/mov2avi.htm)

That's a long way of doing it. And the audio is still uncompressed WAV.

philippas

23rd April 2002, 23:04

Well the method in Nicky's page works well and you can do a 2-pass encoding very easily. The audio yes has to be converted to wav, you can use beesweet for the encoding to achieve very good quality, much higher than using acm codecs.
The avisynth method fails alot of the time and you can't get the audio, you will need to use total recorder for that.
As for installing quickTime software for me is not an option i dislike quickTime software.

Neo Sapien I have been using your way, for a few encodes, but now I want to transcode a 15fps Quicktime movie & not a 24 fps one, the avisynth script you gave me, always creates 24 fps output. What changes should I make?

Stabmaster-Arson

26th April 2002, 10:13

This is how to do it
best way I found, works great, use the Vfapi plugin in tmpgenc with the quicktiume import plugin. Just save the job, convert to vfapi and bamoo recompress whereever and however you wish. If its 60 FPS you may want to decimate to 30 fps BTW, save some filesize and no quality loss to speak of.

@ stab, could you explain this more thoroughly plz? I really don't get it completely... The ones I want to do now are 15 fps.

Head Hunter

26th April 2002, 15:51

just open them in TMPG with the quicktime import filter, select 15 as the fps and you can follow the rest of what he said, or just do it all from inside TMPG.
