Real Media Converting to mpeg4

I have some video's I'd like to convert to mpeg4 so I can place them in iMovie and put them on DVD. I drop the .rm file into ffmpegx and after awhile it shows up. I then set the preferences and click "Encode", but the encoding is really quick and produces a file that doesn't work......here is the info on noe of the .rm's

I don't know if this has anything to do with it, but when I click play in ffmpegx, I hear the sound of the video but for some reason mplayer does not open up to show the video. I'm running on a Mac OSX 2.16 GHz Intel Core 2 Duo. Any help would be greatly appreciated.....really want to get these vids on DVD.

First be sure to have an Intel version of the Real codecs installed in the "ffmpegX" folder in "Application Support".

Then try the "Invert mapping " option as your file seems to have the audio track coming first instead of the video track.

where would I find an intel one?

You have to download them on the mplayer main website. Scroll down to the "Binary Codec Package" section and download the package "Mac OS X x86 20060611".

Inside the zip file you'll find the installer for mplayer, that means it will install the files in usr/local/lib. Open the installer and proceed with the installation.

Under the finder choose "Go to folder..." in the "Go" menu. Type usr/local/lib and press return. This will open a new window where you will find the "codecs" folder containing the Real binaries. Copy this folder in Library/Application Support/ffmpegX and rename it "reallib". That should make it..

I downloaded the codec pack but can't find the usr/local/lib folder. I didn't open the zip file, I just followed the Installation and now I have no idea where it installed it to. Thanks for responding so quick.

I assume the .zip has been automatically decoded by Safari at then end of the download. As for the "codecs" folder, you can't "find" it just by browsing or using Spotlight. It's an invisible Unix folder. The only way to access its content is to use the "Go to folder..." command in the "Go" menu, then type "/usr/local/lib/" (I forgot the initial slash in my previous message).

Sweet some progress......the video now plays in mplayer but when I try to encode to mpg4, it finishes to quickly. I clicked on the Invert mapping option and it finishes quickly and it says failed. Here is the info. from the failed attempt:

You can *only* transcode Realmedia files when using mencoder based settings/presets, not ffmpeg settings/presets.

Sweet Daddy.......Thanks.....IT WORKS!!!!!!

I even tried with spotlight, I tried to look for "codec" folder, no chance.
Any help?
Because until now, FFmpgX says my ".rm" files are invalide....

Thanks!

C'est normal, /usr/local/lib c'est un chemin d'accès vers les dossiers systèmes cachés (de type Unix), et ils portent ce nom quelle que soit la langue de Mac Os X. Ils sont normalement invisibles afin que l'utilisateur lambda ne s'embarasse pas des racines Unix de Mac OS X. Ils ne sont pas référencés par Spotlight. Il faut donc obligatoirement taper tel quel "/usr/local/lib" dans le menu "Aller>Aller au dossier..." pour accéder à cet emplacement.

The folders are called "usr", "local", and "lib" no matter the language of your system. These Unix folders are normally invisible to the user (even with Spotlight). They are completely different elements from the regular "Users" and "Library" folders. To access this path, you have to type exactly "/usr/local/lib" using the "Go>Go to folder..." menu item.

What's the next step, then?

Le chemin d'accès complet au fichier à convertir, ainsi que le nom du fichier à convertir, ne doit pas contenir de caractères spéciaux : points d'interrogation/exclamation, virgules, parenthèses et, le plus fréquent dans les pays francophones, des accents... La présence de ces caractères est la cause la plus fréquente de ce type d'erreur.

The entire file path and filename mustn't have any special character (quotation marks, brackets, etc...)

But it says "non lisible"....

En premier lieu, essaie de faire un test avec un autre clip, par exemple l'un de ceux-là (sans oublier de renommer le .ram en .rm). Dépose ce fichier sur le bureau avant de le traiter avec ffmpegX.
Si il t'affiche toujours "non lisible", c'est qu'il y a un problème avec l'installation des codec Real :
-> vérifie que tu as installé au préalable la bonne version du package de codec (Intel dans ton cas)
-> vérifie que tu diposes bien d'une version Universal de ffmpegX (via la fenêtre "Lire les informations" du Finder)
-> vérifie que tu as bien copié le dossier "codecs" dans le dossier Bibliothèque/Application Support/ffmpegX (il s'agit de la Bibliothèque générale, pas de celle dans ton dossier utilisateur)
-> vérifie que tu as bien renommé cette copie du dossier codecs en reallib avec deux L (ça m'est déjà arrivé de faire l'erreur)
-> vérifie que ffmpegX est bien directement dans le dossier "Applications" et pas dans un sous-dossier quelconque

First try with a sample .rm clip in order to check if it's a probleme specific to your own video, or if it's a general problem. Put the file on the Desktop before trying to process it with ffmpegX.
If you still get the "unable to read" message, then there is probably a problem with your installation of the Real codec package.
-> check that you have installed the correct version on the binary package (Intel in your cas)
-> check that you have an Universal version of ffmpegX (via the Get info window in the Finder)
-> Check that you made a copy of the "codecs" folder in "Library/Application Support/ffmpegX" (this is the general Library folder, not the Library folder in you User folder)
-> check if you correctly renamed this copy as reallib with two L
-> make sure that ffmpegX is located in your "Applications" folder, and not nested in any sub-folder.

In the "Résumé"/"Summary" tab, on the left, you have three fields "format destination"/"output format" (or something like that). In the first field, you can click on the little black triangle ("Réglage rapide") and you will see an array of presets : if you're using these quick settings to do the conversion you can only use a preset using mencoder. These "presets" are included with ffmpegX, there is nothing to find or to upload.

When I'm talking about "settings", I'm talking about the setting of the "video codec" in the "Video" tab, when you are manually fine-tuning the settings (which is the method I usually prefer). But here again, there is nothing to upload, I'm just talking about the choice of the video codec which has to be mencoder based.

Thanks! It worked! Well, it worked... At least draging the .rm file onto the desktop.
Because after that, I tried all encoding combinations possible, but none seems to work...

Tu ne facilites pas la tâche pour déterminer ce qui ne marche pas Parce que là, du coup, je ne sais pas si, finalement, je dois comprendre que c'est juste la conversion qui merdoie, ou si tu n'as même pas réussi à faire identifier le fichier Real par ffmpegX...
It worked ? You mean you actually succeded in having ffmpegX identifying the Real files ? If identfication is OK, but the conversion fails, what is the error message reported
1/ by ffmpegX progress
2/ by the terminal if you check the option "open a terminal window" in ffmpegX
