I use avg bitrate and 2-encoding, should i check turbo first pass??

[botdvd]

Hello.

I use coustom settings and use avg bitrate (3580) and 2-pass encoding. Was told to ckeck turbo first pass.

My two questions are.

If i don`t use turbo first pass, will the encode time be much longer then if i do? Know it take a long time With 2-pass but With or without turbo checked will there be much difference?

I want quality first, will buy a coustom pc for this work. So if i don`t use turbo first pass will the quality be better? If turbo cuts the encode time and With no loss of quality then i will check turbo first pass

Please help me out here, searched and found nothing that say it clearly like i asked.

Thanks.

You asked the same thing on the handbrake forum....

1. If I hadn't known the same message was on the other forum how would I know what program you are talking about? - You haven't mentioned it in your post.
2. Your answer rests with yourself, do an encode/transcode and check the result and time taken e.t.c. Is the result and time acceptable to you?
3. Advice... Stop using two pass bitrate and switch to CRF like everyone else did 10 years ago.

Sorry, not trying to come across as an ass, just trying to help

Thank You. Ok when using CRF on BluRay i want quality but not to big files either, standard is RF20 but checked a sample at 18 and looked pretty good. Any advice what RF setting i should shoot for? All my encodes are 1280x720 and AC3 audio, Wanna burn the encodes on discs for Collection. Length of title will make the encode go up or Down in size, but would like to use same CRF on all encodes.

Yes everyone wants quality but not too big file sizes, you can't have both, usually.

Acceptable file size is down to you, that also goes for quality. 'Standard' on the HandBrake forums if I remember correctly is CRF 20 for 'DVD', not Blu-ray, which would be '22'. The problem is different sources will yield different results. Some things at CRF 22 will look as good as the original, some not. There's no magic number.

The good thing is HandBrake gives you the options to just encode a chapter. Maybe try a few from a few sources and see what you feel happy with.

1pass CRF encoding is a different ball game as oppose 2 pass (pressing any content into same bucket). Every Blu-Ray is different, lenght is different, each movie needs different bitrate to keep same quality, you cannot make any elaborate decision after encoding one or even 5 Blu-Ray movies encoding CRF. So average volume per movie is something you aim for.

To be concrete, I use CRF 18, down-resize 1280x720, like you (it is just stupid movies anyway and originals are always there if needed), also getting 640kbps audio.
Average volume for latest 20 encoded Blu-Rays was 3.39GB. So you might think something like that, again I do not know what content you prefer. To judge resulting volume using CRF after encoding couple of Blu-Rays makes no sense. Of course keeping original audios get volume higher.

i use crf 18 but keep res at 1080. i'm happy with the results.

Many people still use 2 pass encoding, and I do see better results from two pass encoding. On Handbrake I always use turbo-first pass when using 2 pass encoding. I would not worry about that, but if you don't mind the extra time, you can turn off the turbo 1st pass.

If you have a slow computer, or you are encoding a large amount of video, CRF will be a lot faster, because it is only one pass.

But it all comes down to personal preference. You can always experiment with different settings and see which yields better results for you.
