Hello,
I've been doing some test encodes in the trial version.
I set the dvd template and then modified it so:
Max bitrate from 9200 > 9000
min from 2 > 300 (with padding)
avg bitrate 6700 (1st attempt) 5600 (2nd attempt)
I find the resulting m2v files to be consistently 5 - 7 % undersized.
Why is it doing this? I though the whole point of 2-pass VBR is that
it can hit the target size accurately.
I don't think VBR will ever be totally accurate because the results depend on the content. If you want a truly accurate output size, then you must use CBR, since that looks only at the bitrate regardless of content.
Yes, I understand. But surely, the information gained during the first pass
tell the program everything about the content, complexity, compressibility,
etc,etc. IT *should* be possible to get closer to the target, than 5%.
Other encoders can do it.
Well, I'd say the file size estimate is the more inaccurate number since at that point, the software hasn't examined the video content yet. Maybe other software is better at guessing.
I also have noticed consistent undersizing of the encoded video.
Knowing this, I now generally use a more aggressive bitrate (e.g. slightly more than the expected output size)
In my opinion, it would be more problematic if the 2-pass encoding would cause oversized encodes (one would absolutely need to re-encode if e.g. the target disc size has been exceeded)
I've inserted my own background picture for a single page DVD menu. I have added fade in and fade out to the Background Picture Effects and selected Motion Menu. However, in Simulation motion, the menu neither fades in or fades to play.
Did you render the motion menu preview? I forget what the button is called, but you will need to render the preview in order to see what the motion menu will look like.
Will this software enable me to cnvert my video to these specifications? I'm new at this.
Stream Type: MPEG 2 or 4
Video Bit rate: 4-6 Mbps (CBR)
Frame rate: 29.97
Chroma: 4.2.0
Interlacing: Upper Field First/Progressive if MP4
Aspect ratio: 4:3
Width/ Height: 720x480
Audio Type: LPCM or MPEG1 Layer 2
Audio Channels: 2 Channels duel mono(mixed)
Audio Bit rate:192Kbps
Avg Audio Level: 20 Dbfs
You can do most of these. The only one I'm not sure of is the Chroma setting. I can't find it, but maybe it's because I'm not familiar with it.
For Avg Audio Level, there is a Volume Adjustment filter that lets you set a base audio level at a specific dB level.
All other settings are available in the format/output settings.
Hopefully someone can help me... will this software TMPGEnc Video Mastering Works 5 BBS) help me to convert my video to these specifications?

I have a Samsung HMX-Q10 camcorder which records HD video in H.264/MP4 format. While attempting to put together a DVD of my videos in TMPGEnc Authoring Works 4, I try to edit each video clip, but the preview playback only plays the first half second or so normally, and then it stops moving completely. The audio continues to play. It seems the program chokes on it. I can play the videos smoothly through Windows Media Player. I also have the latest version of Quicktime installed on my computer. I have the "low resolution" option checked, but the help says that may not work with certain video formats. It seems to make no difference, so I assume the H.264 is one of those exceptions.
I am running an AMD A4-4000 Richland 3.2GHz Dual-Core CPU, with 4GB of DDR3 1333 RAM. My main hard drive is a 1TB, 7200RPM w/64MB cache, SATA, 6GB/sec Western Digital. The videos reside on a secondary SATA drive.
Does anyone have suggestions on how to get the preview video to play back smoothly? I upgraded my computer JUST for the purpose of editing my HD home movies, so it is quite a bummer to find it still not working. Would upgrading to version 5 work? Or should I install a specific codec to decode the H.265 video faster? Would moving the video to the main hard drive be better? Thank you!
Hi,
I need to get a new pc for 90% Surfing and 10% editing home Videos from my playsport ZX5 (once a month).
As for space-saving reasons i'm thinking on a System something like the following:
Hard to say. TMPGEnc software is generally optimized for Intel processors, but that AMD processor looks faster than the the Intel processor, so it might be faster processing.
I'm considering moving from DVDitProHD to TAW5. Currently in DVDit I'm able to construct a plain, no-frills menu by creating title text over black background at the top frame, typing "chapter 1" "chapter 2" etc. or other text identifying the chapter along the bottom of the menu frame, leaving space between for the motion/video to loop in the menu. I haven't yet found that totally-custom option in the trial version I just installed. Is one available if I don't want to use a fancy template?
There is an issue where 24 bit pcm audio using mpeg2 or h.264/avc video format created in authoring works 4 and 5 will no longer play using vlc player. the format used to play in previous versions of VLC player. 16 bit plays fine as always. please advise if you know of a setting change.
I suggest asking why on VLC's site (forum), considering that its a VLC matter and its lack of support of a video and audio codec. http://forum.videolan.org/
Update.
I uninstalled the current version of vlc player and installed V2.0.0.0. The VLC player played the 24 bit pcm blu ray audio with no issues. Therefore there is a bug in the vlc software somewhere after V2.0.0.0. I posted the issue at the vlc forum. hopefully they will figure it out and create a fix. In the meantime I am going to use v2.0.0.0 because I do not want to risk infecting my computer with malware from downloading older versions from the internet.
Not the first time i hear about bugs in that player. I abandoned it a long time ago because of constant bugs in it and its lack of propper HD support.
Today i use Media Player Classic - Home Cinema 64bit version.
I have 2 video clips that I want to email to a friend. The original size is was more than 100 MB. I used the template settings, (960x540), 25 fps, VBR, etc. Audio-AAC, bitrate 128. The size of both clips reduced to approximately 70MB each. I then changed settings: reduced bitrate to 2000 in stead of 4000- the size of the output clips basically remained the same, also when I changed the 960x540 to 640x360.
What settings are recommended to reduce the size of each clip to less than 5 MB?
Another question, since I have previously just used editing programmes with "fixed" conversion settings. To reduce for instance AVI to MPEG 2 for DVD, what are the best settings to use? I have a Canon Legria HV40, which is a HDV camera and I capture on 1920x1080, "comp out 1080i", which I presume is 1080 interlaced.
I have never been completely happy with the image quality of the DVDs and would appreciate comments about these settings as well.
I would not reduce the size by that huge factor, because it will severely impact the image quality of it.
Instead i would use a free filesharing service from where friends and family then can download the video clips from.
Personally i always use Multiupload to upload homevideo clips to, if i want to share it with friends and family.
Then all i have to do, is to mail them the download link.
But i am afraid i can't help you with the other matter. I always keep videos in original pixel size and try not to touch the bitrate to much. I have a Blu-ray burner, so if i want to burn something in HD to a disc, i always use Blu-ray media.
I guess this is because the MKV's has DTS audio in them, by them selves the TMPGEnc softwares does not support DTS.
Try browsing thrue the other pages of the forum. The solution was posted a while ago on how to get DTS support, input only, not output, by using 3rd party software for rendering.
