  1. Hi,

    I am using Cinema Craft Encoder, 4 Pass, VBR and I was wondering if anyone has experience with setting the max, average and min bitrates in the settings?

    If you have sucessfully encoded AVI's to be encoded to MPEG2 and used in SVCD's/DVD's could you please post some of the bitrates you determined to work the best? (I'm capturing VHS to Avi using the huffy codec)

    I am in the process of making lots of test files to try on my dvd player - maybe this is the only way.....

    Thx in advance!

    Your min should be the lowest amount of bitrate you think any given scene will require, (credits?) You can safely use a min of 0-500 for both SVCDs and DVDs. Unless you run into any playback problems (skipping, freezing) or see any obvious artifiacts during flat scenes (scene changes) than stick to a min of 500 or less.

    As for max, you have two options. If compatibility is of any concern than just use the maximum bitrate allowed in the respective standard you are encoding to. For SVCD the max total bitrate is 2778kbits, so minus your audio bitrate and some multiplexing overhead you are going to be using a max around 2500kbits.

    For DVD use 9800kbits minus total bitrate of all audio tracks.

    If you want exact numbers than use something like FitCD/Fit2Disk to calculate the exact max to use taking into account all overhead for your source, ie: subs, multiplexor, etc...

    Your second option is to go outside of the standards in an effort to increase quality at the risk of decreasing compatibility. This is really only applicable for SVCD, and you will just have to experiment to see what your dvd player will accept and how far you are willing to push it.

    Finally, your average bitrate should be calculated using a bitrate calculator. I prefer to use FitCD/Fit2Disk. With a bitrate calculator you can determine the bitrate to use to make your movie completely fill the desired number of disks. For analogue captures you are probably going to want to shoot for between 45-55 mins per cd in SVCD format and for DVD you are going to be able to fit several captures to disk.

    For DVD I recommend encoding to 352x480/576 and using a bitrate of around 2.5 to 3mbits.

    i thought if you set min bitrate as 0, the encoder automatically chooses like 300 or something as the min bitrate....

    0=automatic.

    It could be 300 or it could be 3mbits, it all depends on the complexity of your source, but if your source is of any length then the resulting min will be low, around 300-500.

    I say to use a min of between 0-500 because regardless of what number you use in this interval the result is probably going to be the same, a min of around 500kbits. People get too hung up with this setting. Just set it to 0 and you should be fine.

  5. I never go below 700 for the minimum setting (SVCD), my player can freeze up the picture from time to time when bitrate drops too low. I dont know of any other players with this problem. Mine is a Pioneer DV-444, used to be a popular player so i guess its lots of them around. Go for 700 when making SVCD if you are concerned with maximum player compatibility.

  6. Thanks for all of your replies,

    Time to make some more test files!
