¿ using FitCD ?

[SnookayDCC]

hey im trying to use fitcd but with all the stuff on the program it is slightly hard to understand. I'm trying to use this program so when i auther my DVD ill be able to resize it properly and be able to see the subtitles in Anime I downloaded clearly. which i posted about here https://www.videohelp.com/forum/viewtopic.php?t=244487&start=0&postdays=0&postorder=asc...ighlight=fitcd

anyone who used or mastered it should compile some info here then an admin can Sticky it. All help will be appreciated.

Ok so I'm assuming you need to do some resizing to your source anyway to make it DVD compliant, and you also want to add borders to keep your subs from being partially lost due to overscanning?

Load your source into Fitcd and it should detect its resolution. Under destination choose either DVD 720 (720x480), DVD 704 (704x480) or 1/2 D1 (352x480) depending on your source's resolution. You want to upsize as little as possible. Of course if you need PAL then check the PAL button. Under "blocks overscan" set this to 0 (for now.) One last thing, there are 3 "round to" sliders. For the sake of simplicity, set all of these to 1. I can explain how to use these but for your purposes you can achieve what you want by just disabling these, which is done by setting all sliders to 1. Just make sure that you don't see any red numbers under the "real aspect" setting. If you do, read my post below. If you now look to the lower left this will be your avisynth script just for resizing.

Now you need to account for overscan, but fitcd's overscan settings are not meant to be used for what you want. By default, increasing the overscan option crops your picture by the designated amount of pixels, and then adds borders over this part. The idea is that the video is going to be cut off anyway so its more efficient to encode black rather then actual picture. You simply want to add borders without cropping anything. So what I would do is save out your avisynth script as is, without adjusting overscan (leave it at 0). Now use the "blocks overscan" option and take just the resulting AddBorders(x,y,x,y) line and copy and paste it into your saved avs file, placing it after your resize line. Just open the avs file in notepad to do the editing.

You'll have to play with the overscan option because different tv's overscan by different amounts. Try a sample encode at 2 first and then go up from there. There are alot more options that you can use in FitCD to tweak your encode, and there are ALOT more available in the full Fit2disk version, but for your purposes this is all you need to mess with.

Now if you are interested in really tweaking your encodes then you need to adjust the "round to" sliders that I mentioned before. You see, during mpeg encoding the picture is grouped into 16x16 macroblocks. FitCD allows you to resize and crop to mod16 which just means that after breaking the picture up into macroblocks there are no left over pixels. This makes encoding more efficient meaning quality will be higher and encoding will be faster. The difficulty is that by rounding your resolution by a pixel here and a pixel there, you can sometimes throw the aspect ratio off. So here's what you do.

There are 3 "round to" sliders. The two on the left affect the X and Y (resolution) after cropping. The one on the right affects the final resolution that you resize to. You ideally want the one on the right set to 32. This provides optimum effiiciency. You ideally want the ones on the left as low as possible. Now what you have to look at is the "real aspect" settings. Again, there's 3 of them. The one closest to the source button (where you loaded your source) is naturally your source's aspect ratio. Just to the right of this is your output aspect ratio after cropping and resizing. If you aspect ratio is off by a noticable amount then this number will turn red. This is what you want to avoid so just play with the sliders until you get within a safe margin of error. The bottom "real aspect" setting is just the aspect ratio after cropping but before resizing. Basically, you are just trying to get all 3 numbers as close to each other as possible, but as long as you don't get the red warning then you are fine.

The full version (Fit2disk) makes all of this much easier since it can actually analyze the pixel aspect ratio of your source and pretty much make most of the necessary decisions itself. If you do alot of encoding then I strongly recommend you purchase it.

Let me know if you have anymore questions, I've been using FitCD and Fit2disk for years.

thanks man. i saved my avis file and did what you said and then i went to read up one what avisynth does. i understand the concept and can sorta see how it will help me. problem is I'm trying to follow the steps posted on the avisynth website for using tmpgenc xpress.

http://www.avisynth.org/Section+2%3A+AviSynth+and+frameserving#q2.4

problem is i cant get the files it says i need "read_avs.dll" i have codecs but thats it. i DLed the mpeg2dec2 file though. can u upload the readavs file?

[adam]

I found this link for readavs http://www.christian-behrens.de/video/download/tmpgenc-readavs.zip

but I'm not sure why its needed. TMPGenc reads avs files just fine without any additional codecs as long as avisynth is installed. Just click on video source, set it to all files, and point it to your avs files.

But, since you are using TMPGenc, which only supports RGB input, there is one additional line you need to add to the end of your avs file.

ConvertToRGB24()

In the future you can add this line in FitCD by clicking the RGB-output option.

BTW: if TMPGenc gives you any errors then play the .avs file in windows media player and note the error message it gives you. It should tell you which line of your script has the problem. This is good for problem solving.
