Better Render Presets for YouTube

Hi there

I have submitted 5 H.264 presets recently. They are awaiting approval.

Here is one of them if you what to test one:

I named it: H.264 1280x720 HQ slow
acodec=mp2 ab=192k ar=44100 ac=2 vcodec=libx264 crf=21 rc-lookahead=40 coder=1 flags=+loop cmp=+chroma partitions=+parti8x8+parti4x4+partp8x8+partb8x8-partp4x4 me_method=hex subq=7 me_range=16 g=250 keyint_min=25 sc_threshold=40 i_qfactor=0.71 b_strategy=1 qcomp=0.6 qmin=0 qmax=51 qdiff=4 bf=3 refs=3 directpred=1 flags2=+mixed_refs+dct8x8+fastpskip+mbtree cqp=0 wpredp=2 trellis=1 weightp=2 deblock=1:0:0 direct=spatial muxer=auto aspect=%dar

Uses mp2 audio because my openSUSE 12.1 ffmpeg does not support faac and ac3 does crash some players. I think mp2 is fairly save because most ffmpeg should support that one.
I think this gives good H.264 video up to the HD 1280x720 format. Maybe higher resolution as well but I havn't tested that.

Any feedback would be appreciated.

Kind regards,
Zebulon

Here is a suggestion for HD 720p using H264 and faac.

f=mp4 acodec=libfaac ar=48000 ab=128k ac=2 vcodec=libx264 minrate=0 b=5000k flags=+loop me_method=umh g=250 qcomp=0.6 qmin=10 qmax=51 qdiff=4 bf=3 b_strategy=1 i_qfactor=0.71 cmp=+chroma subq=8 me_range=16 coder=1 sc_threshold=40 flags2=+bpyramid+wpred+mixed_refs+dct8x8+fastpskip keyint_min=25 refs=3 trellis=1 directpred=3 partitions=+parti8x8+parti4x4+partp8x8+partb8x8 aspect=%dar

If you don't have libfaac, you can change to use libmp3lame.

Hope it can help (let me know).

Hi zebulon,

EDIT >
maybe I´m I was not focused enough ... , but I find it difficult to find your setup among all others, but that is not your fault. Kdenlive should give more Information in the Rendering selection. I think this is really annoying.

I've found your mp2 setup above tomorrow morning. I will do a rendering test right now.

Your Setup ist for 1280x720, so I have to scale my Movie. That´s ok for a test, but the default scaling of Kdenlive isn´t that nice. I prefer the Lanczos method. Every scaling gives a slight blur on the edges.
I will upload all the stuff to my server, as soon as possible.
I will make a package including the original scene.

I think this scene isn´t the best material to do test renderings, but on the other hand, usually I have no perfect Clips :) so it is a good average test.

yours truly,
yt
