Need Quality Type That I must choose

[cyberlion]

Hi,

avi is most popular but it takes lot of pain to reencode it

Please can you tell me some good quality type of movie extension or is it called codec.

I found mkv reencoding is double faster than avi.

I would like comment on which codec is good in quality - best in conversion

[greymalkin]

best quality in a small file size is h.264..you can use the free x264 encoder to create. Any good quality encoder is going to take time, however. even on a fast machine.

A little information about your desired end result would help in offering suggestions.

[cyberlion]

No i don't want to mingle with the resolution and quality - Any x264 offer how much resolution.

I want good resolution - Min. of what i can go is MKV. Any thing in par with it.

AVI, MKV, MP4, MPG, TS, M2TS, MOV, etc are containers -- "boxes" that hold video and audio that may or may not be compressed with any of a number number of codecs. But not all containers are suitable for all codecs. So what you really want to know is what codec will give you good quality with a small file size (and fast conversion times), and what container(s) is suitable for that codec. You may also need to consider what your playback device(s) supports.

h.264/AVC/Mpeg4Part4 has the best compression but it takes the most CPU power to convert. It's also pretty CPU intensive to play back. MKV or MP4 are most common and suitable for this. But AVI can be used too.

Divx/Xvid/Mpeg4Part2 doesn't compress as well as h.264 but takes a lot less CPU power. This is most commonly found in an AVI container.

Mpeg2 compresses even less and takes even less CPU power. You typically find this in an MPG container.

A rough estimate of how much compression you can get: h.264 can compress about twice as much as Divx/Xvid and still maintain the same quality. Divx/Xvid can compress about twice as much as MPEG 2 with the same quality.

A rough estimate of CPU power required: h.264 will require 4 times the CPU power of Divx/Xvid. Divx/Xvid take about twice as much CPU power as MPEG 2.

But a lot of this will depend on the settings used in the codecs and how many cores/threads your CPU has. There's about a 10 fold difference in the slowest (and hence highest quality) settings and the fastest (and hence lowest quality) settings of each codec. h.264 encoders (x264 for example) are usually able to take better advantage of multicore CPU's. So, even though x264 takes 4x longer than Divx on a single core CPU, it may be faster than Divx on a four core, eight thread CPU (Intel i7 for example).

Nice i have sent you an PM. Please Read it.

[lordsmurf]

Quality mostly depends on the source first, the encoding comes second.

ok

I want add Watermark using this -
https://forum.videohelp.com/threads/191496-Put-a-custom-watermark-on-your-video

With that i want to add textsub

I successfully did it.

But i dont file comes out to be 116 MB.

I think it something related to an pop up coming while loading the .avi file saying VBR audio stream detected

I have to use VirtualDubMod. I have no problem with VirtualDub but it doesn't save as MKV as compared to VirtualDubMod

File size = bitrate * running time.

Use a bitrate calculater to determine what bitrate you should use.

It has nothing to do with that.

I have to use VirtualDubMod. I have no problem with VirtualDub but it doesn't save as MKV as compared to VirtualDubMod

VirtualDubMod's MKV output is antiquated. Output as AVI with either program then use MkvMergeGUI to remux into a proper MKV file.

[cyberlion]

ok Now i am confused i used MkvMergeGUI - It did in 9-10 sec. and pop MKV file made.

Well that is nice.

This are my needs-

1)I want to add subtitle - .srt or .sub
2)I want to add watermark with this method.
https://forum.videohelp.com/threads/191496-Put-a-custom-watermark-on-your-video

An Video Movie File of 700 MB i want to re-encode with above needs.

At the least size + Quality must be ok. If the file is around 600-700 MB no problem.

But re-encoding makes time for it to convert is problem.

So it is the deal is between lowering the time limit by using "I don't know encoder" and "Quality Preserved[Pixel Wise]"

I am going to do 3-4 Movies at a time in i7 920 core 8 GB RAM DDR3 with music encoding in background.

I wish this 3-4 movies to be in >60 mins.

That's the thing i want. I added every info. that i wish.

I don't whether it is .mkv or .avi - time and quality is important.

Thanks guys you are really helping me a lot. I will truly like to help if i am able to once.

Please Give exact procedure of how should i do it.

[lordsmurf]

Got the PM. I don't do subs outside of DVDs, so can't help here.

Personally, I'd resize video and encode out to lossless AVI.
Then re-encode with H.264 encoder to mp4 file (I use MainConcept Reference, expensive pro software -- x264 is free alternative)

I don't know that this is possible: "I wish this 3-4 movies to be in >60 mins."

[jagabo]

Use VirtualDub or VirtualDubMod (as per the guide you posted earlier) to make AVI files with hard subs/logos. Use MkvMerge only if you want to remux the resulting AVI files to MKV files.

To match your other requirements (3 or 4 files per hour on an i7 920, 700 MB each) you will want to use Xvid as your encoder, with only moderate motion search settings, single pass, bitrate based encoding (use a bitrate calculator to determine what bitrate will deliver the size you want). X264 will be far too slow and Divx has the multitasking problem I spelled out earlier. If you want to maximize quality with bitrate based encoding you have to use 2 pass encoding -- doubling your encoding time. Your expectations are unrealistic.

[cyberlion]

moderate motion search settings

How? Please any pic with explaination

bitrate based encoding (use a bitrate calculator to determine what bitrate will deliver the size you want

How? Please any pic with explaination. Or any Tutorial of how to choose the bitrate. What exactly does bitrate mean?

I don't understand all its components https://www.videohelp.com/calc.htm

If you want to maximize quality with bitrate based encoding

No moderate quality is well good - no special - i just want it to remain within 700 MB and with moderate quality with subs and watermark.

[jagabo]

moderate motion search settings

How? Please any pic with explaination

The Motion Search Precision and VHQ Mode settings have the most effect on encoding time, especially the latter. The higher you set them the better the quality with bitrate based encoding, or the smaller the file with quality (Target Quantizer) based encoding. But encoding time increases along with those settings. Shown are the default "General Purpose" preset settings. Those will probably be suitable for you (you'll have to test for yourself to see how fast four simultaneos encodes will run with those settings). VHQ can go up to 4 but the difference between 1 and 4 is usually very small. If that isn't fast enough for you try reducing the Motion Search Precision setting a bit. I wouldn't take VHQ Mode down to 0 -- the quality (or file size with constant quality encoding) hit will probably be too big.

bitrate based encoding (use a bitrate calculator to determine what bitrate will deliver the size you want

How? Please any pic with explaination. Or any Tutorial of how to choose the bitrate. What exactly does bitrate mean?

The bitrate determines how big you file is going to be:

file size = bitrate * running time

Or, restated:

bitrate = file size / running time

Since the running time for a particular movie is fixed, the bitrate determines how big the resulting file will be. Ie, if you want a particular file size you need to use the calculated bitrate.

If you want to maximize quality with bitrate based encoding

No moderate quality is well good - no special - i just want it to remain within 700 MB and with moderate quality with subs and watermark.

Why are you so obsessed with 700 MB files? Are you burning to CDs? If you are interested in quality, and not restricted to CD size, you should be using quality based encoding. Let the files turn out whatever size is necessary for the quality you specify. With 1.5 TB drives selling for $100 who cares exactly how big the files turn out.

[cowboyup910]

really good stuff on this thread! thanks

[cyberlion]

Ok i ran 4 movies at once by watermarking and adding subtitles at once. I chose matrix reloaded. I finished with this 4 within 30 mins.
This is First Screen when i started and following sequence-

This is my computer specs-


Ok i dubbed many movies like this. Matrix reloaded was a big success all running well.

I found problem with an another movie Named Night At The Museum 2.

Think the movie is at 00:25:00 - 25 mins. with ongoing audio track name it X1 when i fast forward to 00:45:00 It should have the audio sequence according to the time. But it plays ongoing track of X1. As such only Video got fast forwarded not the audio with it lol!

Any solutions!

[jagabo]

I see you switched to Target Quantizer encoding. Good move.

You might be able to squeeze a little more performance out of the system by limiting Xvid to 2 or 3 threads when running four simultaneous encodes. Otherwise, Xvid may use 8 threads per instance, a total of 32 threads, because it doesn't know their are 4 instances running. Too many threads may slow the system down a bit simply because it's having to juggle so many threads.

Regarding the audio problem, you may have to reencode the audio. Or even demux it with some other tool, fix and reencode it, then mux it back into the video.

[cyberlion]

Sorry Jagado.

I ain't much knowledgeable on Target Quantizer. Is it the best?

I just reserched a bit to find Target Quantizer and Target Bitrate. Still Dumb of what they are.

Why i have problems with each and other avi movies while encoding.

If you say i can do 2 movies at once to improve quality. I have no issue. Though this is at AMD x4 965.

Main system which i am going to have is i7 920. Which will be much better. So Quality within 700 MB.

So my need for quality is increased a bit since i am getting performance @ less than 30 mins.

I have time limit of 60 mins. Thanks.

[jagabo]

It's obvious from your screen caps that you had Xvid set to encode in Target Quantizer mode (constant quality), not bitrate mode.

In Target Quantizer mode (constant quality) you select the quality (indirectly via the "quantizer"). The encoder uses whatever bitrate is necessary at each frame to deliver the quality you asked for. You don't know how big the video will be until it's done.

In bitrate mode you pick the bitrate and the encoder gives you whatever quality it can for that bitrate. It may be low quality or high quality. You won't know what the quality will be until it's done.

With bitrate based encoding you have two basic options: single pass constant bitrate (CBR), and multi pass variable bitrate (VBR). In single pass CBR mode each scene gets the same bitrate. That means some scenes may get more than the need and others may not get enough. In multi pass VBR the encoder uses less bits for scenes that don't need it, and more bitrate for scenes that do need it. Of these two options, multi pass VBR delivers better overall quality but requires at least two passes -- meaning it takes twice as long to encode.

Single pass CBR and Target Qantizer encoding take about the same amount of time because they both work in a single pass.

[cowboyup910]

is just like the encoding use in ConvertxtoDVD 4. i think its producing good quality outputs (very close to the source)

Why i have problems with each and other avi movies while encoding. And how to re-encode audio stream

[jagabo]

Why i have problems with each and other avi movies while encoding.

Because when you download stuff there's no telling what you'll get.

And how to re-encode audio stream

In VirtualDub you can use:

Audio -> Full Processing Mode
Audio -> Conversion... (if necessary)
Audio -> Compression... set codec and parameters

Then encode along with the video.

You can use VirtualDub to export audio for another program:

File -> Open Video File
Audio -> Full Processing Mode
Audio -> Conversion... (if necessary)
File -> Save WAV...

[cyberlion]

1)What is AVI- Open DML and AVI - Legacy.

2)I just made Target tranquilizer to 1.00 and my file size increase more than 40 GB+ and keep increasing in Virtual Dub.


But in VirtualDubMod it converts 700 MB to 2.4 GB with Target tranquilizer to 1.00 which works.

3)What is difference between VirtualDub and VirtualDubMod.

4)Is .ssa better or .srt. I don't want watermarks and subtitles to be removed by any programs.

5)For better audio stream i must choose MP3- VBR and Full audio processing mode. And any more filters in VirtualDub to make it more proper

Since i am able to dub in 30 mins. I have another 30 mins. to refine quality more properly so what do you suggest for this. Any other software to use or any more filters in VirtualDub to make it more proper

EDIT:I just dubbed an movie which had audio problem with Full audio processing mode. Result was excellent. But file comes to about 1.9 GB. That is not at all i want. How to improve that.

EDITED this post around 6 times

[jagabo]

Target Quantizer 1 is too low. Try 3.

VirtualDub: up to date, source plugins, only one audio track
VirtaulDubMod: outdated, no source plugins, but supports multiple audio tracks, built in MPEG2 decoder

[cyberlion]

What about other questions. How can i do Full audio Processing Mode with being under 700MB

[jagabo]

file size = (video bitrate + audio bitrate) * running time

use a bitrate calculater

[cyberlion]

1)What is AVI- Open DML and AVI - Legacy.

2)Is .ssa better or .srt. I don't want watermarks and subtitles to be removed by any programs.

3)How can i do Full audio Processing Mode with being under 700MB. Sorry But how to set it on VirtualDub any filters.

[jagabo]

1) The original AVI spec couldn't handle files over 4GB. ODML added the ability to go over 4GB and some other stuff that's never used.

2) SSA and SRT are just two different text based subtitle formats. If you're burning subtitles into the video it doesn't matter which you use. SSA does allow you to specify properties of the subtitles like font, size, color, etc.

3) file size = (video bitrate + audio bitrate) * running time. For example, with a 100 minute (6000 seconds) movie:

700MB = (video bitrate + audio bitrate) * running time

(rearranging:)

700MB/running time = (video bitrate + audio bitrate)

(convert MB to KB, running time in seconds:)

700,000KB/6000 seconds = (video bitrate + audio bitrate)

(do the math:)

117 KB/s = video bitrate + audio bitrate

(1 byte = 8 bits, multiply by 8 to convert KB/s to Kb/s)

936 Kb/s = video bitrate + audio bitrate

So if you use 128 kbps audio that leaves 808 kbps for the video.

To make your life easy, use a bitrate calculator to get the bitrates. Set the audio and video codecs to use those bitrates. There are many guides here on how to encode with VirtualDub:

Ok i found a way to decompress the audio streaming by lame MP3 compression. Is it the best?

Now i have questions regarding Hard-burned subtitles and watermark.

[jagabo]

Ok i found a way to decompress the audio streaming by lame MP3 compression. Is it the best?

It depends on what you mean by best. It's suitable for your purposes.

[cyberlion]

I just want movies to be reencoded with No-Software Removable Subtitles and Watermark with 750 MB.

So i think i just used Target BitRate with 750 so it auto tweek all the settings right?.

So is that the best.
