StaxRip - Help with getting smaller files.

[Jynks]

Hi there...

I'm trying to find a way to make small video files for uploading to uTube. I record most of my video with a Sony HandyCam that saves as a .TS file.. I use TSMuxer to stitch them together onto my Hdrive and edit in Adobe Premier. Then I render it out to a preset that is in cs6 where it dose a youtube 1080p.

The problem is that these files are still pretty large for my connection out here in the country. The videos are about 20-40mins and I would like to get them to be around 200-300megs.

I ran StaxRip using the settings I found on this youtube video...

The results were very good I thought, but still around 500meg. I would like to try and get it smaller but I am not a encoder, just a noob using "click an encode" systems.

Can anyone help me with the settings to make it smaller. There is a preset called MEDIUM and a QUAILTY values (22) as well as something called TUNE I have set to none... also there is like a billion options in advanced I have no idea what they do.

To get smaller files, and I realise there will be a slight drop in quality, but I hope not to much.. should I drop the "quality slider" or change the "speed" thing?

Any other tips would be cool.. I wish to end up with a 1080p file.

Thanks!

Some thoughts:

- given that you are encoding to mkv for audio you could use opus 96kbits instead of aac 115kbits. Quality is still excellent, and you save about 20kbits/sec

- you can certainly save a lot of space by denoising your clip. I would say, use knlmeanscl to denoise if you have a decent video card. Start with d=1,a=1,h=2.0 and increase or decrease h trying to obtain a well-denoised clip. If you denoise too much you loose too much detail.

- if you are not satisfied with the results of knlmeanscl you could try other alternatives for denoising, I would say try smdegrain or QTGMC with InputType=1 Ezdenoise = 2.0 starting options

- if size is still too large after these things you could try slower x265 presets (but the slower ones are REALLY slow). You should gain some more compressibility

- also, in x265 options try increase bframes (+2), put deblock at 1:1, increase ref. This should help with compressibility

- as a last resort, if you still need a smaller file, increase quality crf. Try 23 or 24 instead of 22, but be aware that the higher you go the worse quality you get.

The best way to save bandwidth is to use a lower resolution and lower fps.

I fail to see why people upload "FullHD Quality" as the macroblocks and smearing make them look worse than a "DVD Quality"...

The rule of thumb is to set the quality you want (ie CRF22) and then use the slowest speed preset you can stand. The slower presets don't necessarily reduce the file size compared to medium, but they should improve the quality a little for a given bitrate or CRF value. The tunings will very likely increase the file size for a given CRF value. Tune Film should retain a little more fine detail than no tuning but it'll increase the bitrate.

How shaky is your camera work? Lots of motion will cause the bitrate to increase as it's harder to compress.I think Premier has some sort of stabilising option but I don't know how good it is. There's ways to do it in Avisynth but it's not something I've done myself.

Aside from that, I'd much prefer to watch good quality 720p than low quality 1080p. There's a line where reducing the resolution to save bitrate is preferable to reducing the quality in further. It's probably in a different place for everyone.

You don't want YouTube preset from premiere, you want fat and big file from there. Either lossless (ut-video) or some hiq intermediate (Iam using cineform, but that is not in cs6).

Then in stax you want deinterlacer (if video was interlaced) and some 2 pass encoding preset, so the final will be exactly as big as you want.

I am sure youtube has somewhere a list of "Best Practice" and this has some restrictions for the video and/or audio - any non-compliant video (and audio) would be reencoded! YOU DO NOT WANT THIS :) so stick to these instructions....

Knowledgeable people will tell you some of these if needed.

Youtube will always re-encode even if you stick to the recommended upload formats.
