I have a MTS file (HD 60i video) taken from my camcorder.
I put this MTS into Premiere timeline.
Then directly export the timeline using Premiere Preset "HD 1080p 29.97" in H264, named the file : file-A.
Here is the file-A media info :
I also export the same file using Premiere H264 "Match Source - High Bitrate", named the file : file-B.Code:General Complete name : D:\Video\Koko - Bali Juni 2018\KokoClip.mp4 Format : MPEG-4 Format profile : Base Media / Version 2 Codec ID : mp42 (mp42/mp41) File size : 236 MiB Duration : 1 min 0 s Overall bit rate mode : Variable Overall bit rate : 32.8 Mb/s Encoded date : UTC 2018-10-21 07:21:06 Tagged date : UTC 2018-10-21 07:21:11 ©TIM : 00:00:02:25 ©TSC : 30000 ©TSZ : 1001 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : Main@L4.2 Format settings, CABAC : Yes Format settings, ReFrames : 3 frames Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 1 min 0 s Bit rate mode : Variable Bit rate : 32.6 Mb/s Maximum bit rate : 40.0 Mb/s Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 29.970 (30000/1001) FPS Minimum frame rate : 29.970 FPS Maximum frame rate : 30.000 FPS Standard : NTSC Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.525 Stream size : 235 MiB (99%) Language : English Encoded date : UTC 2018-10-21 07:21:06 Tagged date : UTC 2018-10-21 07:21:06 Color range : Limited

file-A bitrate is around 32 Mbps, 29.97 fps progressive. File size is around 236 MB.
file-B bitrate is around 6 Mbps, 29.97 fps interlaced. File size is around 48 MB.
I can see the quality difference between file-A and file-B when watching it in 42 inch LED-TV connected to my computer via hdmi.
Anyway, because I want to reduce the file size, so I use Handbrake to do it.
I put file-A into Handbrake, with a setting :
Constant Quality (RF) : 30
X-264 Preset : Medium
Filters : OFF
Name the file : HB-file-A.

Next, I put file-B into Handbrake, with a setting :
Constant Quality (RF) : 30
X-264 Preset : Medium
Filters : De-comb Bob
Name the file : HB-file-B
HB-file-B media info :

HB-file-A bitrate is around 3 Mbps, 29.97 fps progressive. Stream size : 22 MB
HB-file-B bitrate is around 3.4 Mbps, 59.97 fps progressive. Stream size : 24.7 MB
The problem in me :
I thought that the quality of HB-file-A will be better than HB-file-B, because the source (which is file-A) has a high bitrate.
But I cannot see the quality difference between these two files when I watch it in 42 inch LED-TV.
So then I thought "oh... maybe it's because the bitrate is different". (HB-file-A bitrate is lower than HB-file-B)
So I encoded again file-A with Handbrake, this time with Constant Quality 29, named the file : HB-file-A1.
HB-file-A1 bitrate is 3.5 Mbps, 29.97 fps progressive. Stream size : 25.7 MB
Now HB-file-A1 bitrate is almost the same (slightly higher) with HB-file-B.
But again, I cannot see the quality difference between these two files when I watch it in 42 inch LED-TV.
A. The problem is within me. e.g : I have a "common" eyes not a "high definition" eyes.
The "high definition" eyes will be able to see the quality difference.
or
B. The Handbrake encoded quality file will be the same quality from a high bitrate (32 Mbps) or a lower bitrate (6.3 Mbps) source.
So... is it A ? or is it B ?
Thank you in advance.

Why don't you use Voukoder plugin to export directly from Premiere with x264 and skip additional step with Handbrake?
Also, if you ask me, CRF 30 and 29 is too low quality for 1080p. And why is first file progressive and second file interlaced? Makes no sense. -
Thank you for the respond, badyu.
Because I don't know Voukoder plugin, and just now heard it from you, badyu.Originally Posted by badyu17
I realize that. My steps I describe in the post is just a test.Also, if you ask me, CRF 30 and 29 is too low quality for 1080p.
As in Handbrake, there is to use 20 to 23 Constant Quality for HD source.
Because :And why is first file progressive and second file interlaced?
1. I want the final file is progressive
2. I want to see if there is a big difference between :
A. export to progressive from Premiere (HD 1080p 29.97) so in Handbrake encoding, the Filter can be off (that's why the first file is progressive)
B. leave the interlaced MTS when export from Premiere (Match Source) then use Handbrake encoding with the Filter Decomb Bob (that's why the second file is interlaced).
Will it work with my old Premiere Pro CC 7.2.1 ? My Windows 7 is 64bit.Voukoder plugin to export directly from Premiere with x264
I've downloaded the Voukoder.prm file and put it in C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore as instructed on the Voukoder website.
But I cannot find an option to export media with Voukoder in Premiere. Maybe I don't know how to export media with Voukoder in Premiere or maybe my Premiere is outdated so it's not compatible with Voukoder.prm ?
Thank you.
