Encoding a Home Video to Blu-Ray
Just to Preface: I began this project with absolutely no knowledge of video editing, formats, encoding, etc. Everything I know I have pieced together from various internet sources. If any of my assumptions are incorrect, please don't hesitate to correct me. I want to learn.
Over the past few months I have been carefully editing video of my parents trip to china. The initial video was captured in full HD using the AVCHD format and edited in Pinnacle Studio 14 Ultimate. The end product is 158 minutes long. A sample of this video has been encoded using the Windows Media file type with the Preset of HDV 180/60i 1440x1080, 5.1 surround. This sample was streamed over our home network (capable of up to 100 Mbps I believe) and watched through an XBox 360 on a 46 in flat screen (sorry I don't have the exact specs). The video appeared to suffer from the "combing" effect typically associated with progressive encoding vs interlacing. The entirety of this home video has been burned to a standard 4.7 GB DVD. Pinnacle Studio doesn't appear to specify a file type, but a Video_TS folder was created containing .BUP .IFO and .VOB files. Progressive encoding was not checked, so I assume interlacing was used. I was happy with the function of the DVD. No "combing" appeared. However, the quality of the video had to be reduced to %40 and basicly defeats the purpose of having captured in HD. This brings us to my current dilemma. I am planning to re-encode the project to a file (I have no Blu-Ray capable drives in my computer, so it will have to be written elsewhere). There are a number of settings available to me, and I'm not sure which is best to go with: Use Progressive Encoding? (y/n) The only TV in our house with a Blu-Ray player is the flat screen mentioned above. (I assume anywhere else we may watch it will have a comparable TV if they have a Blu-Ray player). Will it benefit from Progressive encoding, if the DVD appeared fine without it? Should I do it anyways? Always Re-Encode Entire Movie? (y/n) Not entirely sure what this is for. Should it be necessary? Image Type: BDMV (AVC) or BDMV (MPEG2) Not entirely sure what difference this will make. Should this be necessary? Thanks so much for your time. |
What is the original file extension name?
Do you still have the original file? The reason I ask is to find out what progs. would be best for editing and compressing (if needed). You can make either or both a DVD and blu-ray compatible file. I have read where videoredo HD can do edits on HD files without re-encoding and perhaps a very basic menu. Whatever editor you use, make sure it isn't re-encoding while making the cuts. If your file can be accepted by BD Rebuilder, that may be the best program for compressing. It can make either a blu-ray file or DVD structure file or both. Another program is called MultiAVCHD, it can do the same plus make menus. Since my knowledge is extremely limited IRT HD camcorder files, hopefully others can contribute ideas for you. You probably need to supply the bitrate of your original files also. You will have to decide whether you will use dual-layer on both your Blu-ray and DVD copies. I have been using BD Rebuilder for compressing a blu-ray to BD-25 and also use it to compress the blu-ray to DVD single layer. Output is very good with this program. That is a long run time for DVD, you may need to use a dual layer or split it on 2 single layers. For Blu-ray, it will likely depend on bitrate whether to use 2 discs or one. I am not sure about blu-ray dual layer, others may have suggestions IRT. I don't use them, too expensive. Use IMGburn for writing to disc(s). |

An HDTV always then scales to the native resolution of that HDTV. In most cases, 720p for older sets, or 1090p for newer sets. Everybody is always watching technically "HD" video, even if the source is much lower quality. To illustrate this, draw a picture on a piece of paper. Cut it up. Now cut it up some more. Did the quality change by making it into more pieces? (i.e., "more resolution). No, of course not. Quote:
Blu-ray specs have changed, had addendums/updates several times, but I don't believe the lack of HDV/1080i has changed. It's not legal, not a valid spec for the BDMV/BDAV formats. Quote:
MPEG-2 is larger file, to achieve same quality as AVC, assuming there's enough space on the disc to do so. Also realize not all authoring programs can use both AVC or MPEG-2, for authoring Blu-ray media. TMPGEnc Authoring Works, for example, is MPEG-2 only. Ideally you'd want AVC, but it depends on which one is allowed by your video workflow (i.e., the authoring tool is the weakest link here). I've also not joined the world of Blu-ray production just yet, but that day is coming. (A need is finally here.) I have, however, been working with HD video for a few years now. Mostly for streaming apps, streaming sites, and other content producers (who would burn their own Blu-ray media, from the HD files delivered on hard drives). |

I've leaned some new stuff, and actually have a clue what I'm doing with these settings. Thanks very much for your help. |
