![]() Would that make any difference because I read that quality 18 is higher quality for blu-ray MP4 files than it is for DVD MP4 files. ![]() Would this help HandBrake to make a better quality MP4 file? Also, I'm using quality 18 for both blu-ray and DVD. On the other hand, the blu-ray MKV source file will be higher quality. On the one hand, the finished MP4 file will be the same resolution as the DVD. So my question is if I use MakeMKV to rip the exact same movie from a blu-ray source and a DVD source, and then I use HandBrake to compress both files with the exact same settings (720x576 quality 18), will the MP4 file compressed from the blu-ray source be better quality than the MP4 file compressed from the DVD source? Or will there be no difference? However, I'm thinking to myself, if I rip my blu-rays with the same HandBrake settings that I use for ripping DVDs (720x576 quality 18), am I any better off paying extra and waiting longer for blu-ray discs at all or should I just buy DVD discs like I always did before? The file size is fine now and the quality seems ok (watching on 1280x720 display which is all I have). So I compressed the blu-ray ripped MKV files to the same settings that I use for DVDs (720x576 quality 18). Using any resolution higher than a DVD resolution (720x576) results in a file which is too big and blu-rays are higher resolution by default. It seems that the main reason for this is the resolution. But when I use quality 18 with blu-ray, the MP4 files are way too big (for me). When I rip DVDs, I use quality 18 and this has always been fine. MakeMKV did a perfect job as always but obviously I need to compress the files with HandBrake. So I have ripped a blu-ray movie with my paid copy of MakeMKV. But I recently got into ripping blu-rays. But it’s also a VERY grainy film that just won’t compress much).I am used to ripping DVDs and have no problems. Films with lots of detail and/or grain can be huge (Black Hawk Down is around 17GB even Handbraked – about 70% of the original. Some films compress much better than others. But remember, this size is just a ballpark average. Typically I factor around 7GB for a blu-ray encoded film (at 20) – I can reduce this to 5GB if I go to 22. But I’m probably one of the few people who have a 9’ HD TV, so it may be overkill for just about anyone else. I’m one of the few who advocates 20 only because I have seen a difference – but again, only a very slight difference, and not with all materials. ![]() Most folks on the Handbrake forum recommend 22 for blu-ray material (and some even higher). ![]() For many blu-rays I actually do lower the quality (raise the RF) to 22 because it doesn’t really matter (comedies, for example – I’d never see any difference with them even on the big screen). At 22 I could see *slight* differences when the material was digital (i.e. I did A/B tests on my 9’ HD screen and could literally not tell the difference between the original blu-ray disc (playing on my PS3) versus a Handbrake encoded original (at 20). Some folks early on thought they’d be “smart” and lower the RF down to 17 or less – and ended up with files that were LARGER than the original. Blu-ray is actually a VERY inefficient format, so it compresses much better than even DVD (which itself is an inefficient format) when encoded to H264. You aren’t just trying to compress to a smaller size, you’re trying to achieve the same quality as the original. The file size increase is around 20% for each two steps (22 to 20, for example).īut file size isn’t the only issue. (Subtitles are a whole different aspect but we can cover them as well as when a blu-ray is more than just the one M2TS file in another post). I would not change ANYTHING else – leave things alone. And there are *some* movies that do need them on (Apollo 13 immediately comes to mind). It won’t hurt to turn them off, but if you ever do any television work (for example, the blu-ray of Star-Trek the Original Series, or Band of Brothers) you will need them on. You can leave Decome/Detelecine at default – they won’t do anything if they aren’t needed and only add a TINY amount of time (a few minutes at most) to the encoding process. I like using 20 for both because it’s one less thing I need to worry about. RF 19 (no lower) is all right for DVD material (not blu-ray) but even then 20 is probably as much as anyone will ever need. But for most people even 22 is just fine (and will be around 20% smaller). Most folks use 22, but I like 20 because I have a 9’ HD projection unit and can indeed see a slight difference. I would NOT change the RF rate to be any lower than 20 for blu-ray material. For encoding blu-ray materials, just use the High Profile preset but change the output type to MKV and (if you have DTS and AC3 decoding receiver(s)) pass through the DTS or AC3 track.
