HD to SD conversion from premiere cs6 have poor quality

[avid]

my project in premiere is progressive and the video is 960x720 with 50fps

Again, 50p is not supported by DVD

But you need a 50p project to make an interlaced 50 fields per second DVD

I see chroma 4:2:2 - is this valid for DVD ?

No, but HCEnc will downsample it properly to 4:2:0, provided the correct interlaced/progressive switches are used

50fps is speed frame per sec not 50p project

Yes, but in the image above you can see that 422 is actually selected for the encode.

In the video world 50fps means 50 frames per second, or 50 progressive frames per second , i.e 50p

An interlaced project would be called 25i (25 interlaced frames per second, or 50 fields per second) , or 50i (50 fields per second) . Both "25i" and "50i" the same thing, just different naming conventions

The setting is here, lower left. DVD compliant button does not fix it.

[poisondeathray]

The "make DVD compliant" button fixes it in HC026 when feeding 4:2:2 input . But you have to specify interlaced or progressive downsampling, or you get the wrong one and chroma artifacts

Does HCEnc convert 50p to 50i (25i) correctly ? I don't think so. If not, he should do that in the script, unless he wants a 25p DVD ?

chroma downsampling interlaced or progressive?

Did you decide on what kind of dvd you're making ?

use interlaced for interlaced dvd
use progressive for progressive dvd


For PAL DVD, your only options are 25p (progessive) , or 50i (interlaced) . 50p is not supported . 50i will have smooth motion, but aliasing/deinterlacing artifacts when viewed. 25p will have choppy motion but better picture quality

You should do those manipulations and resizing in the avs script, along with SD color conversion (Rec601), if frameserving HD intermediate

can you help me to make avs script for pal mpeg 2 for dvd the project is 720p 50fps the capture video is mxf from p2 Panasonic camera

First thing to go from before you start with script, debug mode frame server exports Premiere project, so you have to decide if Premiere will make your 50p turn into 50i by setting your project to 50i. Or you let Avisynth to change it.

If you leave it 50p, project settings, you need to add line in Avisynth to change 50p into 50i:
AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave()

i don't understand why leave 50p project and make 50i i have all videos is progressive and some clips from dslr in progressive

[_Al_]

Your original is 50 full frames per second is that right?
So you should go with 50i DVD because if you go with 25p you will loose temporal resolution, meaning, video could stutter (more or less depending what was your shutter speed when you shot your video) , you simply disregard every other frame converting frame rate from 50p to 25p.
Well, this might not be entirely true, some videoeditors might convert 50p to 25p with frame blending. Not sure what Premiere would do. You might like that or not.

The thing is, with frame server you can do all kinds of tricks. If you like NLE frame blending, you might set project to 25p and let Premiere to convert video from 50p to 25p.

But I'd say 50p to 50i (25i) would look superior. More fluent.

Perhaps you can try to understand the following:

PAL DVD frame size is 720x576, not "720p". Full-farme PAL DVD cannot be any other frame size.

PAL DVD is either 25 frames per second progressive, or 25 frames per second interlaced. You cannot have 50 progressive frames per second in a PAL DVD.

PAL DVD can have only one of two display aspect ratios: these must be either 16:9 or 4:3. You cannot have any other display aspect ratio in a PAL DVD.

I am now under the impression that "DVD" is not what you want. However, if your set top player is a "DVD player" and not a BluRay player, then for DVD you want PAL at the frame size and at one of the frame rates quoted above. You cannot use any other frame size or frame speeds for full-frame PAL DVD.

[poisondeathray]

Your 960x720 video is not a 16:9 frame. That frame size is a 4:3 aspect ratio. Therefore, you should resize the 960x720 to PAL 720x576, convert the colorspace to YV12, and encode it for a 4:3 display aspect ratio.

The P2 MXF (probably DVCPROHD) is not a full raster format (not square pixels). The 960x720 has a DAR 16:9, with a PAR of 4:3. The square pixel equivalent is 1280x720

[sanlyn]

OK, thanks for correcting. 16:9 DAR, then. I'll correct my post.

[avid]

I'm confused enough with 50p 50i 25i 25p end a thousand formats
the first seg have the size of my video 960x720 WHY upscale to 1440x1080

[_Al_]

Not sure what you are trying to say. Do you have more than one type of video on your timeline ?

So far it was established that you use 960x720 only, so all you need to do is frame serve it (if you use frame server), set project properties to 960x720 (first image), then resize it make it interlace in Avisynth. Avisynth script looading into HcEncoder might look like this:

Avisource("signpost_from_frame_server.avi")
ConvertToYV12() # you get it 4:2:0 here
Spline36resize(720,576)
Blur(0.0,1.2) # low pass filter to blur it vertically, to prevent shimmering of interlace lines
Sharpen(0.0,0.5)
#until here video is still 50p progressive
AssumeBFF().SeparateFields().SelectEvery(4, 0, 3).Weave() #this line makes it interlace 50i for DVD from 50p
ColorMatrix(mode="Rec.709->Rec.601", interlaced=true) #changing BT.709 to BT.601 for standard resolution

ColorMatrix you have to download from here and put it in Avisyth plugin folder.

You load that script into HcEncoder and press "Make DVD compliant" and flag it 16:9, in settings 1 for interlace options check "interlace" and "TFF"

i make this test with your script,ColorMatrix is ok which plugin still need more for this script?

[pandy]

You load that script

Excessive blurring - 0.5 - 0.75 should be sufficient to reduce line flicker and flutter. Perhaps even less than 0.5 - depend from content nature.
Resize and matrix conversion should be performed before Blur, Sharpen after Blur is weird and can produce worse result (increase quantizer as bitrate limitations), ConvertToYV12 should be last in chain and it should have flag Interlaced=True.

how I will do that

I have no experience in Script Can someone do it for me

[smrpix]

Keep it simple. 960x720 is DVCProHD P2. That is what your project settings should be. DVCProHD50.

I'm getting the sense that the main thing "wrong" with your DVD is that you've gone from HD to SD and it doesn't look as sharp.

#it is up to You 704 or 720 pixels horizontally i suggest 704 - comment/un-comment one of the lines with #

Spline36resize(704,528).AddBorders(0,24,0,24,color = $000000).Blur(0.0,0.75)
#Spline36resize(720,540).AddBorders(0,18,0,18,color = $000000).Blur(0.0,0.75)

#until here video is still 50p progressive
AssumeBFF().SeparateFields().SelectEvery(4, 0, 3).Weave() #this line makes it interlace 50i for DVD from 50p

ConvertToYV12(Interlaced=True) # you get it 4:2:0 here

[sanlyn]

I doubt we'll get any sort of input or output sample to analyze with or to make a demo for the O.P.. The problem could be the owner's settings, bitrate, resizing, or other factor. Best I could do here is link to a sample of progressive 1920x1080 AVCHD source downsampled to NTSC MPEG. The source AVCHD is from a TV broadcast, captured with Hauppauge HD PVR. The AVCHD source was progressive with 3:2 pulldown interlaced frames. It was inverse telecined and resized in Avisynth, then re-encoded with TMPGenc Plus 2.5, audio resampled to Dolby AC3 with TMPGenc Smart Renderer. The MPEG is 23.976 fps re-telecined for 29.972 playback, which means that 2 of every 5 frames is interlaced, soft-coded pulldown.

The O.P. can view it in a deinterlacing player like MPC-BE or even Windows Media Player to see if he thinks the quality is "bad" using the methods we suggest. The MPEG is about 35 MB.

I get that feeling too. I get the feeling that "too blurry, noise and no sharp" is from making an interlaced DVD and watching it with a blend deinterlace .

Some people expect their DVD to look like their HD source... not going to happen

Premiere is clearly worse for interlaced scaling, but when you have a progressive source, it's fine . AME's h.264 encoder (Mainconcept/Rovi) is clearly worse, but it's MPEG2 encoder isn't that bad. I doubt he will see huge improvement by using HCEnc or something else


@Sanlyn - not a "fair" comparison, because he is in "PAL" land, and an interlaced PAL DVD is going to look worse than a progressive NTSC DVD in terms of picture quality, but smoother in terms of motion . If he were making a 25p DVD, then it would be a closer comparison. And maybe that's what he wants ? Getting information from this guy is like pulling teeth

[sanlyn]

An example of using a smart renderer, proper resizing, and proper re-encoding AVCHD->DVD is all the link is. Interlaced PAL will obviously have differences, but it should at least look clean and undamaged. I don't think we'll get more info from the owner.

Spline36resize(720,540).AddBorders(0,18,0,18,color = $000000)

Why would you do that? Just 720x576 and flag it 16:9 in encoder should be fine. As I understand he has 4:3 anamorphic video, it is 16:9. And any overscan could be a pretty nuisance today.

[avid]

_Al_ your script is best my output file mpeg is beter now,"interlace" and "BFF NOT TFF with TFF have flickering when move camera.
i make it from premiere with frame server,(not export avi) and convert the mpeg2 with HCqui for one hour with some effects the HC convert for 4.30 hour,
audio export from premiere as wav and convert ac3 with TMPGEnc Video Mastering Works 5.
thanks to all

PS:What is the shortest for encoding export as avi with lagarith codec and then encode to mpeg2 in HC or TMPGEnc, what do you suggest for faster encoding?

[sanlyn]

Lagarith is a very fast lossless compressor, fast enough for real-time capturing with lossless compression.

HCenc and TMPGenc Plus 2.5 will both run at about the same speed. HCenc has somewhat of an edge in processing speed with certain types of video. HCenc is more configurable for special purposes (but you have to know what you're doing and why you are changing the default settings). TMPgenc 2.5 comes with excellent image adjustment filters, but they aren't always necessary for digital sources like yours. In any case, both encoders are more configurable and precise than lesser encoders found in most consumer NLE's. These "consumer" encoders are scaled-down versions of more expensive products.

Using HCenc and TMPGenc means that you have to understand the nature of video encoding; they are not one-button automated devices. But they do have good documentation and are not terribly difficult. All of the better quality encoders are slower than the less-than-wonderful encoders in most NLE products. Frankly, HCenc and TMPGEnc do better work, and good work takes time. You can get faster high quality with strictly professional, multi-function encoders -- but they are extremely expensive and require very powerful computers.

Adobe's encoders are decent if not absolutely great, as long as you encode at appropriately high bitrates with 2-pass encoding. Low bitrates mean lower quality. This might have been a problem with some of your early encodes.

TMPGenc Mastering Works is an encoder, with a few features such as adding transitions, dissolves, etc. It also has a time line editor feature. However, it is designed for best quality with lossless AVI for input. It can encode DVD, AVCHD, and BluRay. It is not smart-rendering with video that is already encoded. If all you want for smart-rendering editing is to combine video with AC3 audio for DVD, you are better off with the TMPGEnc Smart Renderer, which does not encode and does not re-encode. There are free apps that can combine audio + video and encode with HCenc, and they will accept losslessly compressed Lagarith AVI. AVS2DVD is a free app that is often recommended. Other members would be familiar with other free software that does the same things.

If you feel that learning more about encoding is not something you want to go into, you can have your lossless Lagarith AVI ready for import into the software you already own. You can use that software to encode and author your AVI input, with audio properly resampled.

I just notice it, after I read your input, in Avisynth script I used BFF and then I told to set TFF in HcEncoder, ....., it has to be same in both instances, sorry.

Source aspect was not clear to me (as was clear for You) thus i assumed it is 4:3 (5:4) thus to prevent aspect distortion such syntax. 704 allow to save few bits and usually is out of visible area anyway.
