The bitrate used is relative to the original bitrate (and size) for that file.
For the DVD conversion, the bitrate stayed within about 300kbps which isn't much in the grand scheme of things. But occasionally when creating quick play playlists from different sourced anime fan subs, file size can vary greatly - my last project has a 2gb HEVC 80 minute video and a 3 GB AVC 20 minute video - the second video was calculated at a much higher bitrate.

In the same vein, flac is a popular anime sub release format, since a lot of sources are Japanese with LPCM.

Trying to IVTC some Pokemon DVDs and am getting combing artifacts. Tried to add FieldDeinterlace as added AVS script, but anything added is placed before the plugins being loaded and the IVTC. Is there a reason for this?

Then tried to compare the results using just the default program deinterlace. Hidden options says that default is SmoothDeinterlace, and no field blending, but the workfiles script shows deinterlacing defaults to FieldDeinterlace with blend=true.

The real question here is why was the audio out of sync the first time you tried it? What kind of audio was it?
6 channel E-AC-3 JOC. BD_RB converted it to ac3.

I kept going back to my project of making episode blu-rays of 24 FPS files. I found out that the length of the imported files in the pseudo bluray is 4 or 5 seconds longer than the original files. That never happens with PAL or NTSC 23,976 of 29,97 episodes. With the use of ''IMPORT_FORCE_FRAMERATE=24'' the length of the episodes stays the same.

I wasn't aware of the ''IMPORT_FORCE_FRAMERATE=24'' option. Nice! Guess it's time to download the latest build. That will come in handy. Will eliminate the extra step I'm taking now when encoding menu background videos that are in 24fps.

The question is are the DVDs true 29.97 fps with 3:2 pulldown? If there is 3:2 pulldown, is the cadence there or was the source material edited 29.97 such that the pulldown cadence is drastically lost. If the 3:2 pulldown cadence is drastically lost, IVTC isn't going to be able to recover the 23.976 frame rate cleanly.

There are other reasons that could be causing the issue. You need to supply us with the technical info regarding the DVD.
