Introduction The bait and switch method of importing DVD footage into Adobe Premiere is designed to allow users to edit with lower quality files, rather than high quality DVD footage. By doing this, users can edit faster and more efficiently, even without a fast computer. This tutorial is designed for people who do not have a background in video editing and gives step-by-step instructions on how to use this method.

Chapter One–Preparation Preparation is the step in which your computer must be set up in a particular way, with the correct software, to edit with DVD footage in Adobe Premiere. The first step is touninstallevery codec pack, encoder, decoder, media player (not including windows media player as it comes with windows) and program that could interfere with editing software and playback codecs. If your computer is brand new and has not had any external video editing or playback software installed then ignore this step. Install Adobe Premiere (/Programs/Adobe Premiere Pro v2.0 Trial):Install Adobe Premiere onto your computer. Install AMVapp v.3b (/Programs/AMVapp):Install AMVapp, making sure that everything is selected when prompted. When installing AviSynth 2.5.7, be sure to select Associate AVS with Notepad. Run tests to confirm everything is working. (If the installationdoesn’t tell you that it failed then everything has passed). If tests fail, try uninstalling AMVapp, rebooting and installing it again. If that fails download an older version of AMVapp from http://www.animemusicvideos.org/guides/avtech/amvapp.html (AMVapp Installation requiresdotnet v2.0 or higher, run dotnetfx.exe if the installation indicates you do not have a sufficient version of dotnet framework) Install MJPEG Codec (/Programs/MJPEG/):Install the Motion JPEG (MJPEG) codec from the Picvideo.exe file. Install CCCP (/Programs/CCCP):Combined Community Codec Pack has nothing to do with editing, however, it will enable complete playback compatibility with any videos and prevent the need to download other codec packs that could interfere with the editing process. Show extensions for known file types:Changing this option inwindows explorerallows you to see file types in the names of files. For example, before changing this option you would see a word document as “Untitled”, after it would appear as “Untitled.doc”. This option is necessary to create text documents that can be converted to AVS scripts later in the tutorial. To change this option,Openwindows explorer (ie. My Computer, My Documents, etc.), select theToolsmenu, followed byFolder Options.... Select theViewtab and under “Advanced settings:” uncheck “Hide extensions for known file types”. Other useful tools used for video editing, located in the/Programs/directory of the DVD include: oGspot–A program that analyses AVI files and determines which codecs were used to encode the video. oVirtual Dub–Virtual Dub Mod comes with AMVapp, however, it is always good to have the vanilla version of the software as well. oVLC–VLC is a common media player that will not affect your video editing. oAbsoluteDestiny & ErMaC's Technical Guides to All Things Audio and Video mk2– Found athttp://www.animemusicvideos.org/guides/avtech/, this is the most in- depth technical guide for video editing that has ever been created.

Chapter Two–Ripping the DVD Ripping a DVD entails copying the DVD files from the DVD to your computer. Due to the way that DVDs are authored you must use software to do this correctly and not just copy and paste the files. OpenDVD Decrypter(installed with AMVapp). Click theModemenu and change it toFile(other modes can be used if required). Select the DVD drive containing the Anime DVD you wish to rip onto your computer. Anime DVDs contain many variousVOBfiles. However, it is not difficult to locate the VOB files which contain the anime episodes or movie that must be ripped. They will be located with the same filename sequence (ie. VTS_01_1.VOB, VTS_01_2.VOB, VTS_01_3.VOB) and will be the largest files on the DVD, normally split into 1gb blocks. Sometimes stray VOB files are also required for the movie or episode, it’s a good rule of thumb to just rip everything you think is necessary and then cut back unnecessary files when creating the project file (.d2v) inDGIndex(see Chapter Three). Select a location to place the VOB files, preferably somewhere with a large amount of free storage space. Once all the requiredVOBfiles have been selected hit theDVD->HDDbutton on the bottom right. Repeat this process for each DVD.

Chapter Three–Creating D2V Project Files D2V files are created to tell the AVS scripts (made in the next chapter) which VOB files you are going to use. This, along with the AVS scripts, creates the foundation of the editing files you are going to use in Adobe Premiere. OpenDGIndex(installed in AMVApp, can be found in the Start menu under Programs/AMVApp/DGMPEGDec). Under theAudiomenu select Output Method -> Disable. This will stop the program from exporting the audio from the DVD, which you do not need as you will be using the video. Open theVOBfiles for a single DVD (collected in the previous chapter) inDGIndex. SelectSave Projectunder theFilemenu and chose a place to save the project file (D2V file). Repeat this process for each DVD.

Chapter Four–Creating AVISynth Scripts (AVS) AVS scripts, using the D2V files, customize the video options. This allows the user to resize and deinterlace the DVD footage, among other things. Createa new text document inwindows explorer(preferably in the same directory as the VOB and D2V files for the specific DVD). This can be done by right clicking the background of the directory (ie. Any place other than the files in the directory) and selectingText DocumentunderNew. Rename the file, with .avs at the end of the new filename (ie. DVD1.avs) The first line of your script should include the following: Mpeg2Source(“C:\YourAMVFolder\Project.d2v”) Substitute “YourAMVFolder” for the directory where your .d2v file is and “Project” to what your .d2v is named. The second line of your script should include the following: Telecide(order=1) Telecide is a method of deinterlacing commonly used on American (Region 1) and Japanese (Region 2) DVDs. If this does not deinterlace your video you can try other deinterlacing methods such as: Fielddeinterlace() tomsmocomp(1,5,1) For Australian DVDs use: tomsmocomp(1,5,1) For more information on what interlacing is and what deinterlaces do, see VicBond007’s guide at (http://www.animemusicvideos.org/guides/working_with_dvd.pdf) The third line of your script should include the following: Crop(4,4,-4,-4) This will crop the first four frames off each side of your video. This line is used to get rid of black borders that certain DVDs have and will not affect your video quality what so ever. The fourth line of your script should include the following: Lanczosresize(640, 480)orLanczosresize(640,360) This will resize the video to the correct aspect ratio and give it a more generic resolution. If your DVD footages is not widescreen you will use Lanczosresize(640, 480). If your DVD footage is widescreen you will have to use Lanczosresize(640,360). Repeatthis process for each D2V file created in chapter three.

Chapter Five–Creating MJPEG encoded AVI files for editing Using the MJPEG codec installed in the first chapter, this chapter will explain how to create an AVI file encoded in MJPEG format, using the AVS scripts created in chapter four. OpenVirtualDubMod(installed in AMVApp, can be found in the Start menu under Programs/AMVApp/VirtualDubMod). Under theFilemenu selectOpen Video File...and select the AVS script created in chapter four. Under theVideomenu selectCompression..., select thePICVideo M-JPEG 3 VfWCodecand pressOk. Under theFilemenu selectSave As...and then pressSave. The video file will have a logo encoded onto it. This will not affect the final product and will only be seen during the editing process. Repeat this process for each AVS file created in chapter four.

Chapter Six–Creating an Adobe Premiere Project File Premiere project files must be created very carefully as some settings selected during creation can’t be changed. Therefore if you discover a setting is wrong half way through a project you will not be able to change it and will be forced to start again. For this reason the following chapter should be followed very thoroughly. OpenAdobe Premiere. A shortcut for the application will be located in the Start menu under Programs. SelectNew Project. There are two tabs at the top of the window, Load Preset and Custom Settings. Select the Custom Settingstab. Under the General Settings select the following options: oEditing Mode:Desktop oTimebase:25.00 or 29.97 depending on the source. (This can be determined by opening the AVS file in Virtual Dub Mod and selectingFrame Rate...under theVideo menu. DVDs manufactured in Australia are PAL format and have a frame rate of 25.00fps. DVDs manufactured in the US are NTSC format and have a frame rate of 29.97fps). oFrame Size:640 and 480 for normal video and 640 and 360 for widescreen video. oPixel Aspect Ratio:Square Pixels (1.0) oFields:No Fields (Progressive Scan) oDisplay Format:Frames oTitle Safe Area:Do Not Change oAction Safe Area:Do Not Change oAudio Settings:Do Not Change Do not change the Capture Settings. Under Video Rendering Settings Change theCompressortoHuffyuv v2.1.1–CCESP Patch v0.2.5. Do not change the Default Sequence Settings. SelectImportunder theFilemenu. Find the MJPEG encoded AVI files created in chapter five and select them. You can now edit your video using the MJPEG files.

Chapter Seven–Bait and Switch Using this method you can make Premiere use the AVS script files instead of the MJPEG files once you have finished editing your video. You can switch between the AVS and MJPEG files as many times as you like, however editing with AVS files requires a powerful computer, which is why you use the MJPEG files to edit with. InAdobe Premiere, right click one of the video files in your project bin, where all your imported files are stored (this will be one of the MJPEG files you have imported). Select Make Offline...and then, making sure thatMedia Files Remain on Diskis selected, press Ok. Right click the same file again and selectLink Media.... Find the AVS script file that correlates with the MJPEG file you have selected and clickSelect(this is the AVS file you used to create the MJPEG file). Repeat this process for each MJPEG video file in the project bin.

Chapter Seven (2)–Alternatives if Bait and Switch crashes If Premiere crashes while attempting to use the first bait and switch method, try using this method, as it has also been proven to work. OpenVFAPIConvwhich can be found in the start menu under Programs\AMVApp\Support Tools. SelectAdd Joband find the AVS Script files created in chapter four and pressOk. SelectConvert. Repeatthe Bait and Switch method discussed previously in the chapter, however, instead of linking to the AVS Scripts,linkto the newly created VFAPI AVI files.

Chapter Eight–Exporting Once you have linked all the video files in Premiere to the AVS scripts you are ready to export the video from Premiere, to be encoded into files that can be played by general media players. In Adobe Premiere, Under theFilemenu, selectExport -> Movie. Premiere will use the settings you have from the project file and you will not need to change them while exporting. These settings can be changed under theSettingsbutton in the Export Moviewindow. If you like, you can select awork areato export rather than theentire sequence. If Premiere crashes during an export you canchange the compressor to “None” or try exporting inseparate work areasandcombiningthem in aseparate sequencein Premiere.

Chapter Nine–Encoding an XviD compressed AVI File XviD compressed AVI files are larger in file size but more compatible. OpenVirtual Dub Modand open the video file exported from Adobe Premiere. Under theVideomenu selectCompression..., select theXviD MPEG-4 Codecfollowed by theConfigurebutton. ChangeProfile @ Levelto Advanced Simple @ L5. ChangeEncoding Typeto Twopass–1st pass. Select theMore...button next to this, uncheck Discard first pass and select Full quality first pass. Under theMoreOptions, Quality Preset, select theMore...button. When Virtual Dub Mod asks if you would like to copy the values of the selected preset, selectYes. Ensure that Motion search precisionis set to 6–Ultra High andVHQ modeis set to 4–Wide Search. Press theOkbutton. Under theStreamsmenu selectStream List.Right click the stream in the list and selectFull Processing Mode. Right click the stream again and selectCompression.... SelectLame MP3 and make sure the 320kbps CBR option is selected. Under theFilemenu selectSave As, label your video and selectSave.

Chapter Nine(2)–Encoding into an x264 compressed MP4 File X264 compressed MP4 files are smaller in file size and are much higher quality. However, they require a faster computer to run and hence are not as compatible as AVI files. In the same directory as the exported AVI file from Premiere, create a newAVS Scriptfile, as described in chapter four. The first line of the script should be: AVISource(“C:\YourAMVFolder\AMV.avi”) Substitute “YourAMVFolder” for the directory where your .avi file is (exported from Premiere) and “AMV” to what your .avi is named. OpenZarx264gui. This can be found in the Start menu under Programs\AMVApp\H264 Tools. Select the folder icon next toInput Videoand find the AVS Script you have just created, which links to the AVI file exported from Premiere. Change theModeto Constant Quantizer and theQuantizerto 18. Set theAudio Bitrateto 320 Kbps

If you are using a computer with a dual core processor go to theAdvancedtab and check Use Multithreading. If you are unsure, leave this option unchecked. Go back to theMaintab and click theEncodebutton.
